Selective dorsal neurotomy (SDN) is a surgical treatment for primary premature ejaculation (PE), but there is still no standard surgical procedure for selecting the branches of the dorsal penile nerves to be removed. We performed this study to explore the value of intraoperative neurophysiological monitoring (IONM) of the penile sensory-evoked potential (PSEP) for standard surgical procedures in SDN. One hundred and twenty primary PE patients undergoing SDN were selected as the PE group and 120 non-PE patients were selected as the normal group. The PSEP was monitored and compared between the two groups under both natural and general anesthesia (GA) states. In addition, patients in the PE group were randomly divided into the IONM group and the non-IONM group. During SDN surgery, PSEP parameters of the IONM group were recorded and analyzed. The differences in PE-related outcome measurements between the perioperative period and 3 months' postoperation were compared for the PE patients, and the differences in effectiveness and complications between the IONM group and the non-IONM group were compared. The results showed that the average latency of the PSEP in the PE group was shorter than that in the normal group under both natural and GA states (P < 0.001). Three months after surgery, the significant effective rates in the IONM and non-IONM groups were 63.6% and 34.0%, respectively (P < 0.01), and the difference in complications between the two groups was significant (P < 0.05). IONM might be useful in improving the short-term therapeutic effectiveness and reducing the complications of SDN.

OBJECTIVE To put forward suggestions on strengthening the quality supervision of Chinese patent drugs and preventing and controlling safety risks by analyzing the current quality situation and quality risks of sampling inspection of Chinese patent drugs. METHODS Reviewed the quality status of Chinese patent drugs for national drug sampling and testing over the past years, introduced the supervision concept and mode of Chinese patent drugs, conducted an overall analysis of the overall quality of Chinese patent drugs for national drug sampling and testing in 2021, focused on the mining and analysis of the main quality problems and risks identified. RESULTS Although the qualified rate of sampling inspection of Chinese patent medicines had shown a positive trend year by year, through exploratory research, it was found that there were still some potential quality risks in the quality of Chinese patent medicines in terms of process prescriptions, internal control standards, raw medicinal materials, excipients, harmful substance residues, illegal addition, etc. CONCLUSION Drug quality sampling and testing plays an important role in strengthening the quality and safety supervision of traditional Chinese medicine. According to the characteristics of different industrial chains of traditional Chinese medicine, different regulatory strategies should adopt, build a more scientific and reasonable regulatory model for Chinese patent medicine, and improve the quality control level and industry standards of Chinese patent medicine.

The adjacent anatomy of the pelvis is complicated, with digestive, urinary, reproductive and other organs as well as important blood vessels and nerves. Therefore, accurate resection of pelvic tumors and precise reconstruction of defects after resection are extremely difficult. The development of medical 3D printing technology provides new ideas for precise resection and personalized reconstruction of pelvic tumors. The “triune” application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis in pelvic tumor limb salvage reconstruction treatment has achieved good clinical results. However, the current lack of normative guidance standards such as preparation and application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis restricts its promotion and application. The formulation of this consensus provides normative guidance for 3D printing personalized pelvic tumor limb salvage reconstruction treatment.

One 24 years old female patient who suffered extremely severe burn in the third trimester of pregnancy was admitted to the Department of Burns and Skin Repair Surgery of the Third Affiliated Hospital of Wenzhou Medical University on 9th May, 2015. Intrauterine distress occurred after injury and stillbirth was confirmed within 12 hours. In cooperation with the obstetrician, the labor was induced on post injury day (PID) 5. Septic shock and multiple organ dysfunction syndrome occurred on PID 8. Through treatments including anti-infection, ventilator-assisted ventilation, cardiotonic diuresis, and escharectomy and skin grafting, the patient was finally cured. This case indicates that it is crucial to grasp the right time and choose a reasonable induction of labor to deal with stillbirth. The scheme of transvaginal induction of labor after shock is a worthy question to explore. The main characteristics of this patient include the extreme paroxysmal changes in breath, circulation, and urine volume within 24 hours after induced labor, which should be monitored dynamically for effective and timely adjustment of respiratory circulation support. This may be another key point for the rescue of this type of patient. To seize the opportunities to perform escharectomy, cover the wound with xenogenic skin graft, and perform skin grafting in time for wound repair remain the top priority.

Coactosin-like protein 1 (Cotl1), a member of the actin-depolymerizing factor (ADF)/cofilin family, was first purified from a soluble fraction of Dictyostelium discoideum cells. Neuronal migration requires cytoskeletal remodeling and actin regulation. Although Cotl1 strongly binds to F-actin, the role of Cotl1 in neuronal migration remains undescribed. In this study, we revealed that Cotl1 overexpression impaired migration of both early- and late-born neurons during mouse corticogenesis. Moreover, Cotl1 overexpression delayed, rather than blocked, neuronal migration in late-born neurons. Cotl1 expression disturbed the morphology of migrating neurons, lengthening the leading processes. This study is the first to investigate the function of Cotl1, and the results indicate that Cotl1 is involved in the regulation of neuronal migration and morphogenesis.

Objective To evaluate the performance of serum small dense low-density lipoprotein cholesterol(sdLDL-C)kit using enzymic method and evaluate the relationship with the severity of coronary heart disease.Methods Performance verification methodology. The analytical performance consisted of accuracy, precision and linearity of serum sdLDL-C kit using enzymic method was assessed. One hundred and twenty healthy persons were recruited to establish serum sdLDL-C reference interval. Two hundred and twelve patients underwent coronary angiography were enrolled in the study.Among them 110 cases were positive for coronary angiography, where as 102 cases were negative. We examined serum levels of sdLDL-C in 110 patients with positive angiography, 102 patients with negative angiography and 120 healthy volunteers. Positive group was classfied into severe group(Gensini score>30) and mild group (Gensini score≤30).Results The accuracy and precision of sdLDL-C examination were in compliance with manufacturer′s statement and there was a good linear correlation(Y=0.9937X-0.1063,R2=0.99) in range of 0.06-2.45 mmol/L. The reference interval of sdLDL-C was 0.15-0.97 mmol/L and without gender and age specificity. The level of sdLDL-C was higher in positive angiography group than in negative angiography group and healthy control group(P<0.01). The level of sdLDL-C was higher in severe group than in mild group(P<0.05). Binary stepwise regression analysis demonstrated that sdLDL-C was independently associated with the severity of coronary heart disease(OR=3.101,P<0.05).ConclusionsExperiment data demonstrated that serum sdLDL-C kit using enzymic method has good performance in the accuracy, precision and linearity. SdLDL-C that plays an important role in the occurrence and progression of coronary heart disease, is an independent important risk of the severity of coronary heart disease.

Objective To evaluate the short-term prediction of high-sensitivity cardiac troponin T (hs-cTnT) and other cardiovascular risk biomarkers in patients undergoing maintenance hemodialysis (MHD).Methods We conducted a cohort survey in 296 consecutive MHD patients whose clinical data were retrospectively analyzed.Before MHD,hs-cTnT and other relative cardiovascular biomarkers were detected.The end point (all-cause death) and time of occurring were recorded in the next 13 months.The differences between survival and all-cause death were analyzed by t-test,Mann-Whitney test and x2 test.The best two percentile cutoff point was calculated by X-tile and the survival rate was calculated by Kaplan-Meier Logistic regression analysis was applied to analyze the odd ratio between high risk and non-high risk hs-cTnT group.Non-high risk group was divided into intermediate risk and low risk group based on the 99th percentile of hs-cTnT in healthy population,to further evaluate its short-term prediction value for MHD patients.The short-term significance of hs-cTnT was proved to be independently associated with all-cause death by Logistic regression analysis.Results The mean value of serum hs-cTnT in survival group was 0.05 (0.03～0.07) ng/mL,while in the death group it was 0.07 (0.04～0.14) ng/mL,which had statistical significance (P =0.027).The best two percentile cutoff of hs-cTnT in MHD patients was 0.1 ng/mL.The survival rate in high risk group (hs-cTnT＞0.1 ng/mL) is lower than it in non-high risk group (hs-cTnT≤0.1 ng/mL) (76.67％ vs.96.62％,P ＜0.05).The odd ratios for high risk group and non-high risk group was 7.288 (P＜ 0.001).Moreover,further grouping the non-high risk group by hs-cTnT =0.014 ng/mL,intermediate risk group (hs-cTnT＞0.014 ng/mL) group has lower survival rate than low risk group (hs-cTnT≤0.014ng/mL),while there wasn't any death case occurred in the low risk group.Conclusions Hs-cTnT is an independent risk factor to all-cause death.Thus hs-cTnT can be a strong indicator of short-term prediction and prognostic evaluation.

OBJECTIVETo explore Chinese medicine (CM) syndrome distribution of chronic hepatitis B virus (HBV) carriers in immunotolerant phase (ITP).

METHODSOne hundred and eighty-five chronic HBV carriers in ITP, seen in the Third Affiliated Hospital of Sun Yat-sen University from May 2009 to December 2010, were admitted in an observational study under the guidance of CM. Patients' CM symptoms and signs, demographics, liver biochemistries, and qualitative HBV DNA were recorded in the questionnaires. CM syndromes were then differentiated to 15 detailed types and analyzed by generalization. Lastly, the location, pathogenic factors and nature of the disease were also assessed.

RESULTSWhen CM syndrome patterns were differentiated to 15 types, there were 27 (15%) no syndrome cases, 94 (50%) single syndrome cases and 64 (35%) compound syndromes cases. The main detailed syndromes included Liver (Gan)-qi depression (LQD), Kidney (Shen)-qi deficiency (KQD), Spleen (Pi)-qi deficiency (SQD) and Kidney-yang deficiency (KYAD). After CM syndromes generalized to five types, their frequency was Spleen-Kidney deficiency (SKD)>LQD>inner dampness-heat retention (IDHR)>Liver-Kidney deficiency (LKD)>blood stasis blocking collateral (BSBC). SKD and LQD occupied 64%. The disease location included Liver, Gallbladder (Dan), Spleen, Stomach (Wei) and Kidney. The pathogenic factors were mainly qi stagnation, qi deficiency, yang deficiency, concurrently dampness-heat and blood stasis. The deficiency syndrome was more than excess syndrome in its nature.

CONCLUSIONSMost of chronic HBV carriers in ITP have their CM syndrome, and the most common types are SKAD, LQD. This study suggests that the natural history may be improved through breaking the state of immune tolerance or shorten the time of ITP by strengthening Spleen-Kidney and reliving Liver qi.
