Vasectomy reversal in China during the recent decade: insights from a multicenter retrospective investigation / 亚洲男科学杂志(英文版)

To date, there is little information about the demography of vasectomy reversal (VR) patients or the factors currently influencing VR effectiveness in China, especially after the universal two-child policy was released in 2015. In this research, demographic data and perioperative medical records of VR patients were extracted from seven major hospitals in different provinces or municipalities of China. Meanwhile, a telephone survey of the patients was conducted to collect follow-up information. Eventually, 448 VR cases from the past 13 years were included. The results were analyzed by stratified comparison to investigate factors that can influence postoperative vas deferens patency and pregnancy rate. Appropriately statistical methods were used, and all of the protocols were approved by the Ethics Committees of the institutes in this research. The results showed that the annual operation volume of VR quadrupled after the two-child policy was implemented. Nonmicrosurgery and a long duration of vasectomy were significantly associated with a lower patency rate. A follow-up survey showed that the general postoperative pregnancy rate was 27.2%. For female partners over the age of 35 years, the postoperative pregnancy rate showed a more severe decline, but only 35.5% of them had been given a fertility examination before their husbands' VR surgery. Our work revealed that more patients in China have been demanding VR in recent years. High-quality microsurgery and a short duration of vasectomy are crucial for restoring patency by VR. Clinical andrologists should perform a preoperative fertility evaluation of the patients' female partners.

Analysis of natural regression and influencing factors of HSIL in the cervix of childbearing age patients / 中华妇产科杂志

Objective: To investigate the natural regression and related factors of high-grade squamous intraepithelial lesion (HSIL) in the cervix of childbearing age women, and to evaluate the applicability of conservative management for future fertility needs. Methods: This study included 275 patients of reproductive age with fertility needs, who were diagnosed as HSIL by biopsy from April 30, 2015 to April 30, 2022, including 229 cases (83.3%) cervical intraepithelial neoplasia (CIN) Ⅱ and 46 cases (16.7%) CIN Ⅱ-Ⅲ. They were followed-up without immediate surgery in the First Affiliated Hospital of Nanjing Medical University. The median follow-up time was 12 months (range: 3-66 months). The regression, persistence and progression of lesions in patients with HSIL were analyzed during the follow-up period, the influencing factors related to regression and the time of regression were analyzed. Results: (1) Of the 275 HSIL patients, 213 cases (77.5%, 213/275) experienced regression of the lesion during the follow-up period. In 229 CIN Ⅱ patients, 180 cases (78.6%) regressed, 21 cases (9.2%) persisted, and 28 cases (12.2%) progressed. In 46 CIN Ⅱ-Ⅲ patients, 33 cases (71.7%) regressed, 12 cases (26.1%) persisted, and 1 case (2.2%) progressed to invasive squamous cell carcinoma stage Ⅰ a1. There was no significant difference in the regression rate between the two groups (χ2=1.03, P=0.309). (2) The average age at diagnosis, age <25 years old at diagnosis were independent influencing factor of HSIL regression in univariate analysis (all P<0.05). There was no significant difference between HSIL regression and pathological grading, the severity of screening results, human papillomavirus (HPV) genotype, colposcopy image characteristics, number of biopsies during follow-up and pregnancy experience (all P>0.05). (3) The median regression times for patients aged ≥25 years and <25 years at diagnosis were 15 and 12 months, respectively. Kaplan-Meier analysis showed that age ≥25 years at diagnosis significantly increased the median regression time compared to <25 years (χ2=6.02, P=0.014). Conclusions: For HSIL patients of childbearing age, conservative management without immediate surgical intervention is preferred if CINⅡ is fully evaluated through colposcopy examination. Age ≥25 years at diagnosis is a risk factor affecting the prognosis of HSIL patients.

Effect of electroacupuncture combined with Donepezil on learning-memory ability and expression of hippocampal β-amyloid clearance-related genes in SAMP8 mice / 针刺研究

OBJECTIVE: To investigate the effect of electroacupuncture (EA) combined with Donepezil on learning-memory ability and gene expression of β-amyloid (Aβ) clearance-related factors in the hippocampus in senescence-accelerated mouse prone 8 (SAMP8) mice, so as to explore their synthetic effect in improving dementia of Alzheimer's disease (AD)．. METHODS: Male SAMP8 mice (30-week-old) were randomly divided into model, medication and EA＋medication groups (n＝6 mice in each group), and other 6 senescence-resistant 1 (SAMR1) mice were used as the control group. Mice of the medication and EA＋medication group received gavage of Donepezil (1.3 mg•kg－1•d－1) once daily for 4 weeks. EA (2 Hz, 1 mA) was applied to "Baihui"(GV20) and "Yintang" (EX-HN3) for 15 min, once daily, 6 days a week for 4 weeks for rats in the EA＋medication group. The Morris water maze (MWM) task (including place navigation tests and space exploration trials) was used to assess the mouse's learning-memory ability. Histopathological changes of hippocampus tissue were observed by H．E. staining. The expression levels of matrix metalloprotein 9 (MMP-9), low density lipoprotein receptor-related protein-1 (LRP-1), P-glycoprotein (Pgp, an important drug transporter responsible for multidrug resistance), Claudin-5 (a component of tight junction strands that serves as a physical barrier to prevent solutes and water from passing freely through the paracellular space between epithelial or endothelial cell sheets of blood-brain barrier, BBB) and Aβ mRNAs of the hippocampus tissue were detected by quantitative real-time PCR. RESULTS: Compared with the control group, the average escape latency of place navigation tests, and the expression levels of MMP-9 and Aβ mRNAs were significantly increased (P<0.01), and the number of platform quadrant-crossing times of space exploration trials, and the expression levels of LRP-1, Pgp and Claudin-5 mRNAs considerably decreased in the model group (P<0.01). After the intervention, the learning-memory ability was significantly improved in the medication and EA＋medication groups (P<0.01，P<0.05), the expression levels of Aβ mRNAs in the medication and EA＋medication groups and MMP-9 mRNA in the EA＋medication group were obviously down-regulated (P<0.01), and those of LRP-1 and Pgp mRNAs in the medication and EA＋medication groups and Claudin-5 mRNA in the EA＋medication group were remarkably up-regulated (P<0.05, P<0.01). The therapeutic effect of EA＋medication was apparently superior to that of simple medication in shortening the escape latency (P<0.05，P<0.01) and in down-regulating the expression of MMP-9 and Aβ mRNAs(P<0.01), and in increasing the number of platform quadrant-crossing times(P<0.01), and expression levels of LRP-1, Pgp and Claudin-5 mRNAs (P<0.01). H．E. staining showed scatted and loose arrangement of neurons in the hippocampus, with reduction of number of cell layers and unclear nucleoli, which was relatively milder in the medication and EA＋medication groups. CONCLUSION: EA can enhance the effect of Donepezil in improving learning-memory ability in AD mice possibly by regulating expression of MMP-9, LRP-1, Pgp and Claudin-5 mRNAs and strengthening the effect of Donepezil in transporting Aβ via BBB.

Effect of Electroacupuncture on Blood-brain Barrier in SAMP8 Mice / 中国康复理论与实践

Objective:To investigate the effects of electroacupuncture on blood-brain barrier to promote intake of drugs into brain of SAMP8 mice. Methods:The male SAMP8 mice (30-week-old) were randomly divided into model group (n = 7), drug group (n = 7), acupuncture group (n = 7) and combined group (n = 7). Other SAMR1 mice were as control group (n = 7). The acupuncture group and the combined group accepted electroacupuncture at Baihui (DU20) and Yintang (EX-HN3), the drug group and the combined group accepted Donepezil, for four weeks. They were observed hippocampus tight junction (TJ) under transmission electron microscope. The activities of acetylcholinesterase (AChE) in hippocampus were detected with immunohistochemistry. The mRNA expression of ZO-1, Claudin-5 and Occludin was detected with real-time quantitative polymerase chain reaction. Results:TJ and basement membrane in the control group, the acupuncture group and the combined group were better than those in the model group and the drug group. AChE was the most in the combined group, and then the drug group and the control group, the acupuncture group and the model group (P < 0.001). The expression of mRNA of ZO-1, Claudin-5 and Occludin was more in the acupuncture group and the combined group than in the drug group (P < 0.01). Conclusion:Electroacupuncture could ameliorate blood-brain barrier disruption and promote drug to enter the brain in SAMP8 mice, which may relate to the adjustion of ZO-1, Claudin-5 and Occludin.

Exploration of Ento-II plastic on analgesic and promoting blood circulation and removing stasis / 中草药

Objective To study the analgesic, activating blood and resolving stasis effect of Ento-II plastic. Methods Hot plate procedure and torsion body method were used as analgesic experimental model to observe the analgesic effect of Ento-II plastic. The acute blood stasis rats experimental model was established through rat subcutaneous injection of high-dose adrenaline hydrochloride and soaked in ice water. Then, the blood stasis focal cerebral ischemia-reperfusion models were established by suture method on the rats. The hemorrheologic indicators were determined. Results Compared with control group, Ento-II plastic could significantly prolong pain thresholds in mice at 30, 60, and 90 min after final administration (P < 0.01). Ento-II plastics 20, 10, and 5 mg/kg dose groups could reduce aceticacid-induced mice writhing times and prolong the incubation period (P < 0.01). The experimental result of rats blood stasis focal cerebral ischemia-reperfusion at 24 h after reperfusion showed that Ento-II plastics 6.67, 3.33, and 1.67 mg/kg dose groups could obviously reduce the neurological function score and whole blood viscosity (P < 0.01). 3.33 mg/kg dose group could significantly reduce plasma viscosity, erythrocyte aggregation index, and casson viscosity (P < 0.05). The effect were similar to that of ligustrazine. 6.67 and 3.33 mg/kg dose groups could significantly reduce casson viscosity (P < 0.01). Conclusion Ento-II plastic has obvious analgesic effect and activating blood and resolving stasis effect.

Clinical outcomes of transperitoneal laparoscopic unroofing and fenestration under seminal vesiculoscopy for seminal vesicle cysts / 亚洲男科学杂志(英文版)

Symptomatic seminal vesicle cysts (SVCs), especially those of a large size, can be removed by surgical treatments. Currently, open surgeries for SVC are rarely performed due to their extensive surgical trauma, and minimally invasive surgical therapies for treating seminal vesicle cysts are still in the early stages. In addition, relevant studies are mostly confined to case reports. In this study, we retrospectively reviewed 53 patients who had received transperitoneal laparoscopic unroofing or fenestration under seminal vesiculoscopy for SVC in our institution. Both surgeries decreased the cyst volume to a significant extent; however, according to the remnant lesion size after rechecking images, seminal vesiculoscopic fenestration tended to have a higher recurrence than laparoscopic unroofing. Regarding complications, two individuals in the laparoscopic unroofing group experienced ureteral injury and rectal injury, while patients in the fenestration group only had temporary hemospermia, which indicates that fenestration surgery tends to have less severe complications than laparoscopic unroofing. There was no solid evidence confirming semen improvement after these surgical therapies in our study. Future studies with a prospective design, larger sample size, and longer follow-up period are required to verify and further explore our findings.

Objective: To explore the relationship between ABO blood group and acute non-ST-segment elevation myocardial infarction (NSTEMI) occurrence. Methods: Our research included 2 groups: NSTEMI group, 1039 relevant patients treated in Anzhen hospital from 2013-01 to 2014-12 were retrospectively enrolled; Control group, 1039 subjects with normal coronary artery which was confirmed by coronary angiography. The Baseline condition including age, previous disease history and ABO blood group was studied. Logistic regression model was used to conduct single and multivariate analysis. Results: In NSTEMI group and Control group, blood type A was 287/1039 (27.6％) vs 259 (24.9％), type B was 345 (33.3％) vs 356 (34.3％), type AB was 102 (9.8％) vs 114 (11.0％) and type O was 305 (29.4％) vs 310 (29.8％), ABO blood group distribution for A and non-A, B and non-B, AB and non-AB blood group, O and non-O had no statistic meaning between 2 groups, P>0.05. Logistic regression analysis indicated that with adjusted risk factors of MI such as age, gender, hypertension, diabetes, hyperlipemia, cerebrovascular disease and smoking, the patients with blood types A, B and AB had the similar risk for NSTEMI occurrence than type O patients; there was no relationship between ABO blood group and NSTEMI occurrence. Conclusion: ABO blood group had no relationship to NSTEMI occurrence.

Effect of electroacupuncture on expressions of VEGF and CD31 in MCAO model rats / 针灸推拿医学（英文版）

Objective:To investigate the effect of electroacupuncture (EA) at Ganshu (BL 18) and Shenshu (BL 23) on vascular endothelial growth factor (VEGF) and platelet endothelial cell adhesion molecule-1 (PECAM-1)/CD31 around the cerebral infarction focus in middle cerebral artery occlusion (MCAO) rats and the possible mechanism, thus to provide a new strategy for the treatment of cerebral ischemic stroke by acupuncture. Methods:A total of 180 healthy male Sprague-Dawley (SD) rats were randomly divided into a sham operation group, a model group, an acupoint group and a non-acupoint group, 45 rats in each group. MCAO model was established using the modified line-embolus method in all rats except for those in the sham operation group; rats in the acupoint group were treated with EA at Ganshu (BL 18) and Shenshu (BL 23); rats in the non-acupoint group were treated with EA at the control points; rats in other 2 groups were only subjected to bundling without treatment. Ten rats in each group were randomly selected on the 3rd day, the 14th day and the 21st day after acupuncture stimulation to test the neurological function impairment. The expression levels of CD31 and VEGF were also detected. Results:Compared with the model group and non-acupoint group, the neurological function score of the acupoint group was decreased at each time point, and the differences were statistically significant (P<0.05,P<0.01). The expressions of VEGF and CD31 in each group were the lowest on the 3rd day, reached the peak on the 14th day and still remained at high level on the 21st day. And the differences among groups were statistically significant both on the 14th day and the 21st day (P<0.05,P<0.01). Compared with the model group and the non-acupoint group, the expressions of VEGF and CD31 in the acupoint group were increased, and the differences were statistically significant (allP<0.05). Conclusion: EA at Ganshu (BL 18) and Shenshu (BL 23) can significantly improve the neurological function score of MCAO model rats, and shows protective effect on cerebral ischemia. The protective mechanism may be related to the up-regulation of CD31 and VEGF expression around the cerebral infarction focus in the MCAO model rats and induction of angiogenesis.

Laparoscopic permanent sigmoid stoma creation through the extraperitoneal route versus transperitoneal route, [A meta-analysis of stoma-related complications]

To compare laparoscopic extraperitoneal colostomy with transperitoneal colostomy for construction of a permanent stoma by measuring the incidence of parastomal hernia, and other postoperative complications related to colostomy. The meta-analysis was carried out in the General Surgery Department of the Second Affiliated Hospital of Soochow University, Suzhou, Jiangsu Province, China in 2014. A literature search of Medline, EMBASE, Cochrane database, and the Chinese Biomedical Literature Database [CBM] from the years 1990 to 2014 was performed. The literature searches were carried out using medical subject headings and free-text words: extraperitoneal colostomy, transperitoneal colostomy, laparoscopic extraperitoneal colostomy, rectal cancer, laparoscopic abdominoperineal resection, parastomal hernia, permanent stoma, and colostomy-related complications. Two different reviewers carried out the search and evaluated studies independently. One randomized controlled trial and 6 retrospective studies were included. A total of 378 patients [209 extraperitoneal colostomy and 169 transperitoneal colostomy] were identified. Our analysis showed that there was a significantly lower rate of parastomal hernia [odds ratio 0.10; 95% confidence interval 0.03-0.29, p<0.0001] in the extraperitoneal colostomy group. However, the other stoma-related complications were not significantly different between the 2 groups. Colostomy construction via the extraperitoneal route using a laparoscopic approach can largely reduce the incidence of parastomal hernia. Laparoscopic permanent sigmoid stoma creation through the extraperitoneal route should be the first choice after laparoscopic abdominoperineal resection

Naloxone Postconditioning Alleviates Rat Myocardial Ischemia Reperfusion Injury by Inhibiting JNK Activity

To investigate the alteration of c-Jun N-terminal kinase (JNK) activity after myocardial ischemia reperfusion injury (MIRI) and further explore the effect of naloxone postconditioning on MIRI. Forty male Sprague Dawley rats were randomly divided into five groups: sham operation (sham, n=8); ischemia reperfusion (IR, n=8); IR+naloxone 0.5 mg/kg (Nal L, n=8); IR+naloxone 1.0 mg/kg (Nal M, n=8); IR+naloxone 2.0 mg/kg (Nal H, n=8). Pathological changes of myocardial tissue were visualized by HE staining. The expression of p-JNK, and the apoptosis of cardiomyocytes were investigated with Western blotting and the TUNEL assay, respectively. Irregular arrangement and aberrant structure of myocardial fibers, cardiomyocytes with granular or vacuolar degeneration, and inflammatory cells infiltrating the myocardial interstitial regions characterized MIRI in the IR group. Signs of myocardial injury and inflammatory infiltration were less prominent in the Nal-treated groups. The expression of p-JNK in the sham group and in all Nal-treated groups was significantly lower than that in the IR group (p<0.01). The apoptosis index of cardiomyocytes in the IR group was significantly higher than in the sham group (p< 0.01). The apoptosis indices of cardiomyocytes in all Nal-treated groups were significantly reduced to 55.4%, 26.2%, and 27.6%, respectively, of the IR group (p< 0.01). This study revealed that Naloxone postconditioning before reperfusion inhibits p-JNK expression and decreases cell apoptosis, thus alleviating MIRI.

The control group was treated with mini-invasive surgery by arthroscopic mopping, followed with post-operational intra-articular cavity injection with sodium hyaluronate injection, 20 mg every week for 5 times continuously. The therapeutic effect and the changes in scores of clinical symptoms and signs before and after treatment in the two groups were observed and compared.</p><p><b>RESULTS</b>Outcome of 3-month follow-up showed the effective rate was 90% in the treatment group and 93.33% in the control group; scores of clinical symptoms and signs effectively improved in both groups, but the improvement on the 4 items (joint pain, swelling, soreness of loin and knee, and cold aversion of knee) was superior in the treatment group, while that on the other 4 items (pain during squatting or half-squatting, up stairs or down stairs, joint stiffiness and joint kinetic capacity) was superior in the control group (P < 0.05).</p><p><b>CONCLUSION</b>Both MSW and mini-invasive surgery have definite curative effect on KOA but with different particularities.</p>

Clinical observation of arthroscopic medial patellofemoral ligament overlap and lateral patellar retinaculum release in treatment of patellofemoral pain syndrome / 中国骨伤

<p><b>OBJECTIVE</b>To explore the therapeutic results of surgical treatment for patellofemoral pain syndrome.</p><p><b>METHODS</b>One hundred patients (35 males and 65 females, ranging from 50 to 70 years old with an average age of 63 years) with patellofemoral pain syndrome were randomly and equally divided into treatment group and control group. All patients underwent arthroscopic treatment. The patients in treatment group were treated with medial patellofemoral ligament overlap and lateral patellar retinaculum release, and the patients in control group were just treated with lateral patella retinaculum release which is a current widespread operation.</p><p><b>RESULTS</b>All patients were followed-up with the mean time of 13 months, and were evaluated with HSS (hospital for special surgery) scoring system for the therapeutic effect. The mean score of treatment group (73.52+/-11.17) and control group (65.50+/-13.70) had statistical difference (P<0.05), which indicated that the therapeutic effect of medial patellofemoral ligament overlap and lateral patellar retinaculum release for treatment of patellofemoral pain syndrome was satisfying.</p><p><b>CONCLUSION</b>Compared with lateral patellar retinaculum release, this procedure is superior in correcting the abnormal movement of patellofemoral joint, easily balancing patellofemoral joint space, effectively relieving the pain of anterior knee. No postoperative complications occur, such as intraarticular haematoma, necrosis and dislocation of patella and so on.</p>
