ObjectivesTo systematically review the efficacy and safety of local endometrial mechanical stimulation in patients with recurrent embryo implantation failure in vitro fertilization.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect clinical controlled studies on the efficacy and safety of local endometrial mechanical stimulation in patients with recurrent embryo implantation failure from inception to March 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 10 studies, including 8 randomized controlled trials and 2 case-control studies, and involving 1 274 patients were included. The results of meta-analysis showed that: the clinical pregnancy rate of endometrial mechanical stimulation group was higher than that of control group (RR=1.40, 95%CI 1.04 to 1.89, P=0.03). However, no significant differences were found in implantation rate (RR=0.75, 95%CI 0.50 to 1.13, P=0.17), live births rate (RR=1.38, 95%CI 0.99 to 1.93, P=0.06), miscarriage rate (RR=0.83, 95%CI 0.55 to 1.24, P=0.36) and rate of multiple pregnancy (RR=0.90, 95%CI 0.61 to 1.35, P=0.63).ConclusionCurrent evidence shows that, for patients with repeated implantation failure, mechanical endometrial stimulation before re-transplantation may help to improve the clinical pregnancy rate of test-tube infants, however, it has no significant effects on implantation rate, live birth rate, abortion rate, multiple pregnancy rate and ectopic pregnancy rate. Due to limited quality and quantity of the included studies, more high quality studies are needed required to verify above conclusions.
Objective To investigate the clinical features, chest imaging manifestations, pathological changes, diagnosis and treatment of sarcoidosis with pleural effusion as the initial manifestation, and to analyze the possible causes of misdiagnosis, so as to help clinicians improve their understanding of sarcoidosis with pleural effusion as the initial manifestation, and reduce the rate of clinical misdiagnosis and missed diagnosis. Methods The general data, clinical manifestations, imaging examinations, pathological findings and outcomes of 4 patients with sarcoidosis with pleural effusion as the first manifestation admitted to Ningxia Medical University General Hospital from January 2019 to December 2020 were retrospectively analyzed. Results Out of these patients, 3 were female and 1 was male, with an average age of 50.3 years. The main clinical features were cough, expectoration, chest tightness, shortness of breath and other common respiratory symptoms. Chest CT indicated right pleural effusion. After admission, closed thoracic drainage, tracheoscopy, thoracoscopy, pleural biopsy and cervical lymph node biopsy were performed to obtain pathology. Combined with imaging and pathology, diagnosis was made. After hormone therapy, symptoms and imaging were improved. Conclusions Sarcoidity-related pleural effusion is relatively rare as the first episode, with no specific clinical symptoms and no specific physical and chemical properties of pleural effusion. Non-caseous granulomatous lesions can be found pathologically, and the diagnosis needs to rely on clinical, imaging and pathological comprehensive judgment.
ObjectiveTo explore the feasibility and clinical efficacy of laparoscopic sentinel lymph node biopsy combined with endoscopic submucosal dissection(ESD) for patients with early gastric cancer(EGC).
MethodsThe clinical data of 26 cases who received ESD combined with laparoscopic sentinel lymph node biopsy for EGC between March 2009 to August 2013 in Affiliated Hospital of Jiangnan University were analyzed retrospectively. These patients first underwent laparoscopic sentinel lymph node(SLN) biopsy. If frozen sectioning examination suggested there was lymph node metastasis, laparoscopic D2 radical gastrectomy would be operated. However, the ESD would be operated if the frozen sectioning examination was negative.
ResultsThe total numbers of SLN were 95, and mean numbers of SLN were 3.7±1.4(range from 1 to 6). Two patients with positive SLN underwent laparoscopic-assisted distal gastrectomy and 24 patients with negative SLN underwent ESD. The disease free survival(DFS) and local recurrence rate after ESD for EGC was 91.7%(22/24) and 4.2%(1/24), respectively. And the total DFS for all patients was 96.2% (25/26).
ConclusionESD for EGC is a safe and feasible procedure, combined with laparoscopic sentinel lymph node biopsy conforms more to the concept of principle of radical operation.

Objective To summarize the basic principle of electrical impedance spectrum technology and the latest progress in the diagnosis of thyroid carcinoma. Methods By the domestic and overseas literatures review， medical application and diagnostic prospect in thyroid carcinoma of electrical impedance spectrum were summarized. Results Electrical impedance spectrum was a kind of somatic function imaging， whose measurement results was objective， and it could diagnose thyroid carcinoma in early stage effectively. In addition， it could be used as a complementary form of fine needle aspiration biopsy， improving the diagnostic accuracy rate of thyroid carcinoma， thereby reducing the unessential thyroid operations. Conclusion Electrical impedance spectrum technology is a potentially useful imaging modality for diagnosing thyroid carcinoma in early stage， and functions as a auxiliary clinical diagnosis method for fine needle aspiration biopsy.
The present study was to develop and design a new sonography rigid bronchoscopy and corollary vacuum-assisted biopsy device system with less injury and complication. The system combined ultrasonic-probe with ultrasound catheter, a new medical ultrasound technique, and rigid bronchoscopy (RB) which is improved with an auxiliary vacuum-assisted biopsy device. The principle of the device is vacuum suction and rotary knife. The reduced outer diameter of the RB led to less pain and lower complications for the patient. With the help of ultrasonic-probe (30 MHz), lesions and blood vessels can be identified clearly and unintentional puncture and damage to blood vessels can be avoided. Plenty of lesions can be obtained quickly through the vacuum-assisted biopsy device without getting puncture needle in and out repeatedly. The novel endobronchial sonography rigid bronchoscopy and matched vacuum-assisted biopsy device has many remarkable advantages. It can enlarge the applied range of the RB from endobronchial to mediastinal lesions, avoiding unintentional puncture of vessels. Obtaining multiple samples with a higher accuracy rate than that by other sampling techniques, minimizing operation time, alleviating pain and decreasing the complication rate, the system makes up the technical deficiency for the diagnosis and treatment of the mediastinal lesions, to a certain degree.

The serum CA19-9 had moderately elevated in 2 patients. the ferroprotein was obviously increased in 2 patients. All the patients were confirmed under the abdominal CT scans and the liver pathological biopsy.
ConclusionPatients with fever and liver area pain as intial symptoms, and with chronic hepatitis B and space-occupying lesions, who should be alert for ICC.
ObjectiveTo evaluate the difference between the tracheal intubation connected to conventional ventilation (TI-CV) and rigid bronchoscopy connected to high frequency ventilation (RB-HFV) under general anesthesia on patients with transbronchial cryobiopsy (TBCB).MethodA prospective, randomized, controlled trial was conducted in interstitial lung disease patients with TBCB from August 2018 to February 2019 in the First Affiliated Hospital of Guangzhou Medical University. According to the different methods of intubation, the patients were divided to a TI-CV group and a RB-HFV group randomly. The operating duration, extubation duration, total anesthesia time, heart rate, blood pressure and arterial blood gas analysis were collected and analyzed.ResultsSixty-five patients were enrolled. There were 33 patients with an average age of (48.0±15.0) years in TI-CV group and 32 patients with an average age of (48.8±10.8) years in RB-HFV group. The basic line of body mass index, pulmonary function (FEV1, FVC and DLCO), arterial blood gas (pH, PaO2 and PaCO2) and heart rate (HR), mean arterial pressure (MAP) had no significant differences between two groups. At the first 5 minutes of operation, the pH was (7.34±0.06) and (7.26±0.06), and the PaCO2 was (48.82±9.53) and (62.76±9.80) mm Hg in TI-CV group and RB-HFV group respectively, with significant differences (P=0.000). At the end of operation, the pH was (7.33±0.06) and (7.21±0.08), the PaCO2 was (48.91±10.49) and (70.93±14.83) mm Hg, the HR were (79.6±21.1) and (93.8±18.7) bpm, the MAP were (72.15±13.03) and (82.63±15.65) mm Hg in TI-CV group and RB-HFV group respectively, with significant differences (P<0.05). There were no differences in the operating duration and extubation duration between two groups. The total anesthesia time was (47.4±8.8) and (53.3±11.6) min with significant difference (P=0.017). Five minutes after the extubation, there were no significant difference in the pH, PaO2, PaCO2, HR and MAP between two groups. No serious complications occurred in either group.ConclusionsCompared with rigid bronchoscopy, TI-CV under general anesthesia is more conducive to maintain effective ventilation, and maintain the HR and MAP stable during the TBCB procedure. TBCB procedure should be performed by TI-CV under general anesthesia in patients with poor cardiopulmonary function.

ObjectiveTo investigate the metastatic status and risk factors of axillary non-sentinel lymph node (NSLN) in breast cancer patients with 1–2 positive sentinel lymph nodes (SLN), and to provide theoretical basis for exemption of axillary lymph node dissection (ALND) in these patients. Methods A retrospective analysis was performed on 54 patients diagnosed with breast cancer who underwent sentinel lymph node biopsy (SLNB) and confirmed to have 1–2 positive sentinel lymph nodes (SLNS) and received ALND in the Department of Thyroid and Breast Surgery of Tongling People’s Hospital from January 2018 to April 2023. The patients were divided into NSLN metastatic group (17 cases) and NSLN non-metastatic group (37 cases) according to whether there was metastasis. Chi-square test was used to compare the basic information and clinicpathological features of the two groups. The independent risk factors for axillary NSLN metastasis were screened out by multivariate binary logistic regression model. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of independent risk factors combined with axillary NSLN metastasis. Results There were 54 cases with 1–2 metastasis of SLN, 17 cases with axillary NSLN metastasis (31.5%). The incidence of axillary NSLN metastasis in patients with tumor at T1 stage (maximum diameter ≤2 cm) was only 14.3% (4/28), however, the metastatic rate of axillary NSLN in patients with tumor in T2–T3 stage (maximum diameter >2 cm) was as high as 50.0% (13/26). The axillary NSLN metastasis rate was only 21.2% (7/33) with 1 SLN metastasis, while the axillary NSLN metastasis rate was 47.6% (10/21) with 2 SLN metastasis. Univariate analysis showed that T stage (tumor diameter >2 cm), 2 SLN metastases, number of SLN >5 and tumor with vascular embolus were more likely to develop axillary NSLN metastases (P<0.05). Multivariate binary logistic regression analysis showed that T stage (tumor diameter >2 cm) and 2 SLN metastases were independent risk factors for axillary NSLN metastasis in breast cancer patients, the area under ROC curve of combined prediction of axillary NSLN metastasis by the two was 0.747, 95%CI was (0.657, 0.917), sensitivity was 0.765 and specificity was 0.649. Conclusions The combination of tumor T stage and the number of SLN metastases can better predict axillary NSLN metastasis in breast cancer patients. ALND is recommended for breast cancer patients with T stage (tumor diameter >2 cm) and 2 SLN metastases to reduce the risk of residual axillary NSLN metastasis.
