ObjectiveTo establish a hereditary deafness genetic screening cohort and conduct prospective follow-up to evaluate the effectiveness of the Nantong newborn genetic deafness screening program. MethodsA study based on traditional screening of newborn hearing was conducted from January 2016 to June 2021. Newborns in six hospitals in Nantong were screened for 15 hotspot mutation loci in four common deafness genes. Cohort follow-up was conducted. ResultsA total of 40 403 newborns were included, with a carrier rate of 39.5 per 1 000 for the four common deafness genes. In total, 168 children with hearing loss (HL) were identified at screening and follow-up, of which 56.5% (95 cases) had severe or very severe HL. The detection rate of HL was significantly higher with combined screening than with traditional screening (3.0‰ vs. 3.9‰, P<0.001). All four carriers of pathogenic mutations with normal hearing developed late-onset HL within 2 years of age. At the end of follow-up, six of the polygenic heterozygous mutation carriers had congenital HL and five had late-onset HL. Carriers of polygenic heterozygous mutations were more common as compared to other carrier mutation populations (2.1% vs. 68.8%, P<0.001). In addition, 525 carriers of the SLC26A4 mutation and 118 carriers of the MT-RNR1 mutation were identified and their parents were counselled during the combined screening, and no children with HL was identified during the follow-up period. ConclusionGenetic screening for deafness improves the detection of HL at birth. It is recommended that carriers of pathogenic mutations with normal hearing at birth be followed up every 3 to 6 months until the age of 2 years. Carriers of polygenic heterozygous mutations should undergo extended screening for deafness genes and have their hearing monitored more intensively for early detection of late-onset or progressive HL.
Objective To investigate the application of free flaps in combinedtransplantation and its clinical outcome. Methods From January 1991 to December 2003, 56 cases of combined transplantation involving cutaneous or myocutaneous flaps were performed to repair extremely large soft tissue defects, large-sized skin and segmental bone defects and to simultaneously reconstruct the missing thumb andrepair the associated skin defects in the first web space.Of the 56 patients, 37 were males, 19 were females. Their ages ranged from 5 to 41, 27.6 in average.The transplants included latissimus dorsi myocutaneous flap, scapular flap, lateral femoral flap, big toe skin-nail flap, and fibula. To establish blood circulation in the transplants, the common vascular pedicle was anastomosed directly to the vessels in the recipient site in 35 cases but to the selected vessels in the healthy limb in 21through a cross-bridge procedure. Results With failure in 2 cases of combined transplantation of latissimus dorsi myocutaneous flap and vascularized fibula, all the transplants survived well. In the 32 cases of long bone defects with successful repair, the transplanted fibulas united with host bones 14.5 weeks after operation on the average. A mean follow-up of 28 (10-128) months revealed thatfunction in all cases was recovered, while one patient, who underwent a successful combined transplantation of latissimus dorsi myocutaneous flap and vascularized fibula, required amputation of the involved leg 3 years after repair because of the repeated ulcers in the toes. Conclusion The application of free flaps incombined transplantation can lead to an effective repair of complicated tissue defects of the limb and to a successful reconstruction of the associated missing thumb.
ObjectiveTo investigate the decision of combined liver and kidney transplantation (CLKT) after renal transplantation, provide surgical therapeutic experience for those patients with liver and renal insufficiencies and hepatorenal syndrome and summarize the risk factors, demerits and merits, and operative indications of CLKT.
MethodsThe data of three successful CLKT cases of our centre from Feb. 2014 to Jan 2015 were retrospectively analyzed, and these three patients had kidney transplantation before. We also reviewed the latest associated literatures.
ResultsThree patients got successful operations of CLKT and had very good recovery of renal function several days ofter operaton. Two of them discharged a few weeks after surgery, and one of these two patients got severe pulmonary infection of fungus two month after CLKT but recovered under proper therapy finally. The third patient died of severe mixed infection one month after CLKT.
ConclusionsThe surgical techniques and rejection are not the main impact factor to the prognosis of CLKT after renal transplantation. Infection is the biggest trouble to which we should pay most of our attention. We should decide whether to do synchronous or nonsynchronous CLKT according to the situation before surgery. Moreover, the systematic therapy administration after CLKT is very necessary for the patients' long-term survival.
Objective To systematically review the influence of frailty on the prognosis of non-cardiovascular surgery heart failure (HF) patients and to provide references for its prevention and management. Methods CNKI, VIP, CBM, WanFang Data, PubMed, EMbase, Web of Science, and The Cochrane Library were searched to collect cohort studies on the prognosis of non-cardiovascular surgery HF patients with frailty from inception to November 1st, 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Then, meta-analysis was performed using RevMan 5.3 software and Stata 14.0 software. Results A total of 20 studies involving 11 127 patients were included. The results of meta-analysis showed that frailty increased the risk of all-cause mortality (HR=1.72, 95%CI 1.61 to 1.84, P<0.000 01), hospitalization (HR=2.06, 95%CI 1.26 to 3.37, P=0.004), and combined endpoint (HR=1.59, 95%CI 1.37 to 1.84, P<0.000 01) in non-cardiovascular surgery HF patients. Conclusion Current evidence shows that frailty can increase the risk of all-cause mortality, hospitalization, and combined endpoints in non-cardiovascular surgery HF patients. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo discuss the CT characteristics of combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC), and analyze the reasons for its misdiagnosis.
MethodWe retrospectively analyzed the CT data of 7 patients diagnosed to have combined hepatocellular carcinoma and cholangiocarcinoma by postoperative pathological analysis between January 2009 and February 2015. We analyzed such characteristics as location, shape, density, enhanced features, surrounding invasion, mediastinal lymph node metastasis, cirrhosis and pyoperitoneum of the disease.
ResultsThere were 7 tumors among the 7 patients. Plain scan showed slightly lower density nodules or masses. After the enhancement of arterial phase, 5 tumors showed obvious inhomogeneous enhancement but 2 mild marginal enhancement. During the portal venous phase and the delay stage, the regional degree of tumor foci was significantly decreased, but some regions sustained annular or nodular and patchy enhancement. Among the 7 cases, the portal vein was invaded in 2, bile duct in 1, lymph node metastasis in 2, cirrhosis in 1, and peritoneal effusion in 1. Preoperative diagnosis was correct in only 2 cases and the other 5 cases were misdiagnosed by CT.
ConclusionsThe cHCC-CC possesses some characteristic appearances on CT. Analyzing the characteristics carefully combining with symptom and cytological examination of hydrothorax can reduce the incidence of misdiagnosis.
Objective To discuss the performance of multi-disciplinary team (MDT) of colorectal cancer treatment within West China Hospital in Sichuan University. Methods To compare the therapeutic effect between groups of MDT model and non-MDT model by retrospectively analyzing the data of patients who diagnosed colorectal cancer and accepted in-hospital therapy during December 2006 and May 2007. Results The in-hospital days of the MDT model group during the perioperative period and in the surgical ward were less than that of the non-MDT model group ( Plt; 0. 05) , but there was no significant difference between the two groups about the total hospitalization time. And the MDT model group had a higher rate of cancer resection ( P lt; 0. 05) . Although the incidence of anastomotic leakage and bleeding as early postoperative complications didn’t show any variations between the two groups , the non-MDT model groupencountered more early postoperative ileus ( Plt; 0. 05) . During the 5－ 10 months follow-up , there came out less cancer recurrence rate in the MDT model group than the other ( P lt; 0. 05) . And the morbidity of anastomotic stricture and ileus didn’t show any statistical difference between the two groups. Conclusion The combined-therapy st rategy ofcolorectal cancer has showed a priority to routine ways , not only the more reasonable time arrangement for therapy , but also the more satisfied surgical outcomes. However , the factors correlated to the efficacy of the MDT model are not clear ; the MDT model still needs to be improved that a morereasonable and effective perioperative MDT model may come t rue.
Objective To construct an evaluation index system of the competitiveness of private hospitals, and to provide references for guiding, supervising, and managing the high-quality development of private hospitals. Methods An index pool was constructed by the literature analysis method. Index screening was completed using the modified Delphi method. The analytic hierarchy process, entropy weight method, and combination weight method were used to determine the index weight. Results The competitiveness evaluation index system of private hospitals was constructed, which included 5 primary indexes and 36 secondary indexes. The combination weight methods were resource allocation (0.366 8), service capacity (0.470 8), service efficiency (0.033 7), quality and safety (0.121 3), and financial management (0.007 3). Conclusion The constructed evaluation index system of competitiveness of private hospitals is scientific, targeted, and operable.
【Abstract】Objective To study the clinical application of laparoscopic operation. Methods The clinical findings from 13 840 cases of laparoscopic surgery in this hospital from 1992 to 2005 were reviewed retrospectively.Results Laparoscopic operation were performed successfully in 13 653（98.6%）,187 cases were transferred to open operation. Complications were occurred in 115 cases, including common bile duct injury in 3 cases. Combined treatment with laparoscope and endoscope were performed in 162 cases. Eleven thousand three hundred and fiftytwo patients had been succeeded in followup survey. Over 90.0 percent of patients recovered smoothly. Conclusion Laparoscopic operation may be applied in a more extensive scope. The major complications can be reduced by strict procedures of laparoscopic operation. The combined treatment of laparoscope and endoscope should be further studied and widely used.

ObjectiveTo observe the clinical efficacy of ulinastatin combined with low-dose arginine vasopressin in treating severe pulmonary contusion.
MethodSixty patients with severe pulmonary contusion were enrolled in our hospital between April 2012 to June 2014 year. All the patients were randomly divided into three groups. They were respectively defined as a routine treatment group (group A, n=20), an ulinastatin treatment group (group B, n=20), and a combined treatment group (group C, n=20). The respiratory frequency (RR), oxygenation index, partial pressure of carbon dioxide (PaCO2), the change of chest X-ray and the change of serum interleukin-6 (IL-6), IL-8 levels were compared among three groups before and after therapy.
ResultThe respiration frequency(RR) and the concentration of serum IL-6, IL-8 levels were decreased in the group C before and after treatment with statistical differences (P=0.000, 0.000, 0.000). PaO2/FiO2 and PaCO2 were significantly increased in the group C before and after treatment (P=0.000, 0.000). After treatment for 7 d, the respiration frequency (RR) and the concentration of serum IL-6, IL-8 of patients in the group B decreased significantly compared with those in the group A (P=0.000, 0.043, 0.000). While PaO2/FiO2, PaCO 2 and the score of chest X-ray increased significantly in the group B (P=0.010, 0.000, 0.000). Compared with those in the group B, RR and the concentration of serum IL-6, IL-8 of patients in the group C decreased significantly (P=0.000, 0.045, 0.000), while PaO2/FiO2, PaCO2 and the score of chest X-ray increased significantly (P=0.043, 0.010, 0.001).
ConclusionUlinastatin combined with low-dose arginine vasopressin shows obvious effects in the patients with severe pulmonary contusion. And its therapeutical effects are better than that of the other two treatment options.
