Objective To explore the effect of hemorrhage on cell apoptosis in the hippocampal CA1 region of rats under controlled hypotension (CH).Methods A total of 36 Sprague Dawley rats were randomly divided into 2 groups: Group C (with no CH) and Group H (with CH).According to different ratios of blood loss to total blood volume, Group C and Group H were redivided into 6 subgroups (6 in each group):C_1,H_1(10%);C_2,H_2(20%);C_3,H_3 (30%). Induced by so-dium nitroprusside and esmolol, the mean aterial pressure in Group H was decreased to 50～55 mmHg and kept for 10 minutes, and then blood loss was started, keeping the pump speed. Without CH, the same style of hemorrhage was performed in Group C. The aterial pressure was increased 60 minutes later after the hemorrhage.Expression of bcl-2 and caspase-3 protein was detected by immunohistochemical method, and apoptosis cells were detected by TUNEL staining. Results The average optical density of bcl-2 and caspase-3 was higher in Group H_3 than that in Group C_3(P＜0.05). There were more apoptosis cells examined by TUNEL in Group H_3 than in Group C_3(P＜0.05).Conclusion Thirty percent blood loss under controlled hypotension can induce cell apoptosis in hippocampal CA1 region in rats.

Objective To study on the relationship between psychological harmony and mental health of health care providers. Methods Surveys on psychological harmony and mental health were conducted in 313 health care providers in Heibei Province by psychological harmony and SCL-90 questionnaire. Results The general psychological harmony,and mental health level of health care providers is lower than the national level; The psychological harmony and its dimensionality of health care providers is affected mainly by many factors such as emotional stability, the level of patients' cooperation, on-duty situation in holiday time, salary, the rate of solving difficult miscellaneous diseases, the number of medical tangle and paranoid symptoms.etc., among which solving difficult miscellaneous diseases effectively is the most important factor. Conclusion The general psychological harmony situation does not affect health care providers' mental health.

Objective To evaluate the effect of stent implantation using Multimodal CT in patients with MCA and ICA stenosis. Methods Twenty-six patients with ischemic cerebrovascular disease who received MCA or ICA stent implantation in ChongQing xinqiao Hospital were recruited. Multimodal Stroke Assessment Using CT Score (MOSAIC) was used to evaluate the Neuroimaging data before stent implantation and Alberta Stroke Program Early CT Score (ASPECTS) to evaluate the time to peak (TTP) of CTP before and after stent implantation. Results Patients were divided into 4 groups based on scores: 4 scores, 5 scores, 6 scores, and 7 scores groups. the improvement degree was increase by 31.7%±14.17%、38.6%±15.73%、43.3%±10.3%、358.6%±13.45% in 4 scores, 5 scores, 6 scores, and 7 scores groups, respectively. The paired t test demonstrated that there were a statistically significant difference among four groups(H=10.673, P <0.05). Preoperative MOSAIC score was positively correlated with the improvement of ASPECT score for TTP, with a correlation coefficient of 0.579 ( P <0.002). Conclusions Multimodal CT is a sensitive assessment for the evaluation of ischemic cerebrovascular disease and patients with a higher MOSAIC score may benefit more from stent implantation.

Objective To investigate the preoperative management and the clinical effeciency of Lichtenstein tension-free hernioplasty in adult patients with inguinal incarcerated hernia.Methods Clinical data of 86 patients with inguinal incarcerated hernia were analyzed retrospectively.Hernia was repaired with Lichtenstein tension free after reposition.Results There were 59 male patients and 27 female patients with median age of (63 ± 18) years.There were 8 patients with liver cirrhosis.The operation was performed successfully in all patients.Segmental bowel resection with end-to-end anastomosis was performed in 38 emergency cases.Operative time was 20-120 min,with an average time of 54 min.The postoperative hospitalization was 5-17 d,with an average of 8 d.There were 7 cases of skin ecchymosis at the scrotum,there were no intestinal perforation,hepatic encephalopathy and upper gastrointestinal hemorrhage after operation.In early series of 24 cases without drainage tube left in place,there were 10 cases of fat liquefaction,10 cases of hydrops of hernial sac,6 cases of seroma and 3 cases of wound infection after operation.After 12 to 48 months of follow-up,there was no mortality after 2 years,no hernia recurrence.Conclusions Tension free repair in the treatment of incarcerated inguinal hernia is safe and feasible.

Objective The objective of this study was to investigate the effect of Wnt pathway inhibitor-ETC-159 on pro-liferation and migration of oral squamous cell carcinoma(SCC-15)cells and to explore its mechanism.Methods SCC-15 cells were treated with DMSO and ETC-159 for 12 h or 24 h.Cell proliferation was detected by CCK8 kit.Transwell assay was used to de-tect the ability of cell migration.Western blotting was used to detect cell migration related to proteins i.e.Wnt3a and β-catenin,pro-liferation and migration related proteins i.e.c-Myc,cyclin D1,CD146.Results After treated with ETC-159 for 12 or 24 h,the proliferation,migration and expression of Wnt3a,β-catenin,c-Myc,cyclin D1 and CD146 in SCC-15 cells were significantly de-creased when compared to the DMSO group(P<0.05).Conclusion Wnt signaling pathway inhibitor-ETC-159 can inhibit the proliferation and migration of SCC-15 cells by decreased levels of c-Myc,cyclin D1 and CD146.

Objective To assess the long-term effectiveness of the transvaginal high uterosacral ligament suspension (HUS) in women suffering from advanced pelvic organ prolapse (POP).Methods A retrospective review of records identified 118 women who underwent transvaginal HUS with or without additional concomitant anterior and (or) posterior repairs from June 2003 to August 2009 in the First Affiliated Hospital,General Hospital of People's Liberation Army.Of 118 women,104 women completed the follow-up during study period;these 104 women were analysed.Follow-up visits were performed 2,6 and 12 months after surgery and then annually.Anatomic results of POP was established by pelvic examination using pelvic organ prolapse quantitation system (POP-Q) staging.Funtional results were obtained by patient global impression of improvement (PGI-I),pelvic floor distress inventory-short form 20 (PFDI-20) and pelvic floor impact questionnaire short form (PFIQ-7).Surgical success required the fulfillment of all 3 criteria:(1) prolapse leading edge of 0 cm or less and apex of 1/2 total vaginal length or less;(2) the absence of pelvic organ prolapse symptoms as reported on the PFDI-20 question No.3 (Do you usually have a bulge or something falling out that you can see or feel in your vaginal area?);and (3) no prolapse reoperations or pessary use during the study period.Results The mean follow-up time was (9.1 ± 1.5) years.The overall surgery success rate was 91.3％ (95/104) according to above all 3 criteria.Prolapse recurrence rates were isolated anterior 6.7％ (7/104),isolated apical 0,isolated posterior 2.9％ (3/104) and multiple compartments 1.0％ (1/104).Five women (4.8％,5/104) developed bothersome vaginal bulge symptoms.None of recurrent women underwent retreatment,including either surgery or use of a pessary at last follow-up.The subjective satisfaction rate was 90.4％ (94/104).PFDI-20 and PFIQ-7 scores showed a statistically significant improvement from preoperative 72 and 65 points to postoperative 17 and 9 points respectively (all P＜0.01).There was a 2.9％ (3/104) rate of intraoperative ureteral kinking and 3.8％ (4/104) rate of postoperative morbidity.Conclusions The transvaginal HUS for vault prolapse offers good long-term anatomical results with excellent vault suspension.With additional concomitant anterior and (or) posterior repairs,it will be a reconstructive surgery for the majority of advanced POP.It is minimal traumatic and appropriate for different type of POP,especially for the eldly patients.It is worthy of being popularized for clinical application.

An effective, reliable and practical staging is of great help to the diagnosis and treatment of malignant tumors. Cervical cancer is a malignant tumor using clinical stage in gynecological tumors, but staging lacks objectivity in judging the tumor size, para-uterine invasion, vaginal margin, vascular invasion and so on. By October 2018, the International Federation of Obstetrics and Gynecology (FIGO) had revised the 2009 FIGO cervical cancer staging that had been used before.However, the changed points of the 2018 FIGO cervical cancer staging are controversial.

Objective:To investigate the short-term effects of articular injection of hyaluronic acid combined with glucocorticoid in patients with knee osteoarthritis.Methods:From October 2017 to June 2018, a total of 188 patients diagnosed with knee osteoarthritis received parallel articular injection. There were 60 cases with mild knee osteoarthritis, 72 with moderate and 56 with severe according to the WOMAC knee functional score. There patients were divided into group rank Ⅰ48 cases, Ⅱ 49 cases, Ⅲ 45 cases, Ⅳ 46 cases according to the knee joint X-ray Kellgren-Lawrence classification. The unified treatment regimen was 2.5 ml Sodium Hyaluronate (SHA) injection for the first time, SHA 2.5 ml and compound betamethasone injection (CBI) 1 ml for the second week, and 2.5 ml of SHA for the third week. WOMAC score and Lequesne index were used to evaluate joint function before the first injection and after SHA and SHA+CBI injection. The improvement rate of Lequesne index ≥30% or improvement rate of WOMAC score ≥25% was regarded as effective treatment.Results:Lequesne index and WOMAC score decreased gradually in the mild, moderate and severe groups after 3 weeks of injection. Among these patients, the improvement rates of Lequesne index after SHA injection and SHA+CBI injection were 36.44%±8.46% and 49.26%±13.75% in the mild group, 23.09%±12.61% and 30.66%±14.95% in the moderate group, and 10.50%±8.78% and 11.07%±6.52% in the severe group. The improvement rate of WOMAC score in the mild group after SHA injection and after SHA+CBI injection was greater than 25%. After SHA injection, the improvement rate of WOMAC score was 13.06%±10.21% in the moderate group, and 27.49%±13.61% after SHA+CBI injection. Those in severe group were all less than 25%. Kendall's staub correlation analysis results showed that there was a strong positive correlation between WOMAC function score and X-ray Kellgren-Lawrence classification ( r=0.744, P<0.001). The Lequesne index and WOMAC scores of the Kellgren-Lawrence X-ray classification decreased gradually after 3 weeks of injection. The improvement rate of Lequesne index period in group rank Ⅰ after SHA and SHA+CBI injection was 36.64%±10.05% and 52.00%±8.19%, respectively. That for group rank Ⅱ was 32.05%±8.09% and 41.95%±10.53%, group rank Ⅲ 16.93%±10.34% and 27.77%±10.25%, group rank Ⅳ 7.52%±5.53% and 7.60%±6.66%. The improvement rate of WOMAC score period in group rank Ⅰ after SHA and SHA+CBI injection was 29.48%±11.77% and 42.59%±13.55%, respectively. That for group rank Ⅱ was 26.72%±10.21% and 30.49%±16.90%, group rank Ⅲ 13.78%±5.96% and 23.05%±9.52%, group rank Ⅳ 4.77%±3.80% and 4.27%±4.23%. Conclusion:For mild or X-ray classification Ⅰ, Ⅱ knee osteoarthritis patients, articular injection SHA or SHA+CBI are effective. Further, SHA+CBI is better than single injection of SHA. SHA+CBI injection was effective for moderate knee osteoarthritis patients. For severe or X-ray classification Ⅲ, Ⅳ patients, SHA or SHA+CBI injection at interval are invalid.

Objective To explore the clinical management and outcomes of polypropylene mesh and sling exposure after reconstructive pelvic surgery(RPS). Methods A total of 110 cases of mesh and sling exposure after RPS were analyzed, who admitted between Jan. 2002 and Oct. 2017 in First Affiliated Hospital of PLA General Hospital, in which 3 cases were referred from other hospitals. Mesh and sling exposures were identified in the outpatient clinic and categorized and managed according to International Continence Society and International Urogynecology Association(ICS-IUGA)classification about category, time and site(CTS)of mesh complication. Outpatient management included observation, topical estrogen use and mesh removal. Management in hospital included surgical removal of exposed mesh and repair of the resulting defects under the anesthesia. Seventy-four cases were managed in the outpatient setting, and 36 cases required inpatient management. Follow-up was consecutively performed from 1 month to 10 years. Objective outcome included the surgeon′s assessment of the healing state of the vaginal mucosa. Subjective outcome was evaluated with patient global impression of improvement questionnaire(PGI-I). Results One hundred and ten patients with mesh exposure were classified according to the different RPS underwent. There were 95 cases from transvaginal mesh surgery, 5 cases from anti-stress urinary incontinence sling surgery, and 10 cases from sacrocolpopxy. The outpatient group healed at an average of(3.0 ± 1.8)months. Of the 36 patients who required inpatient management, 21 cases healed completely at an average of 7 days after one surgery. The remaining 8 cases required either two or three times surgeries or conservative management. In the outpatient group, the PGI-I scale very much better was found in 65 cases(87.8％)and much better in 9 cases(12.2％). In the inpatient surgery group, the scale was very much better in 30 cases (83.3％), and much better in 6 cases(16.7％). Conclusions Among patients with mesh exposure after mesh-augmented RPS, 2/3 of patients with a CTS classification 1-3 could be managed in the office,and remaining 1/3 with CTS classification 4-6 need operation under anesthesia in hospital. If the mesh and sling exposure could be scientifically classified, according to the size, site and accompany symptoms, as well as pain, most of the mesh complications after explosure could be resolved. Using the pelvic floor repair and polypropylene mesh sling, the majority of the patients could get a better outcome, without affecting the effect of the original operation.

Objective To evaluate the indications and clinic outcomes of vaginal high uterosacral ligament suspension (HUS) for treatment of recurrent advanced pelvic organ prolapse (POP). Methods This retrospective study analyzed 42 women with recurrent advanced POP who were referred to Fourth Medical Center of PLA General Hospital and underwent transvaginal HUS between November 2005 and January 2018. Primary surgeries included 30 vaginal colporrhaphy, 5 Manchester operation, 5 transvaginal mesh repair,2 sacrospinous ligament fixation.The median time for recurrence from primary pelvic floor repair surgery was 9 months, including 14 cases (33%, 14/42)≤3 months (median time was 2 months) and 25 cases (67%, 28/42) longer than 3 months (median time was 18 months).The rate of recurrent prolapse in stageⅢorⅣ was 79% (33 cases), 45% (19 cases) and 17%(7 cases) in anterior, apical and posterior compartment respectively. Results Transvaginal high bilateral uterosacral ligaments were identified and used for successful vaginal vault suspension after vaginal hysterectomy and residual cervical resection in all 42 consecutive patients. The cases of transvaginal mesh used in anterior wall and posterior wall were 25 (60%, 25/42) and 3 (7%, 3/42) respectively. There was no major intra-and postoperative complications,such as ureter and other pelvic organ injury. The median time of follow-up was 5.3 years after transvaginal HUS. The points of pelvic organ prolapse quantification system reduced significantly and point C improved from+0.3 cm to-8.2 cm after reoperation (P<0.01). The objective cure rate were 100% (42/42) both in apex and posterior compartment,while 93% (39/42) in anterior compartment. None had reoperation or pessary usage for recurrence of prolapse. Conclusion Transvaginal HUS with vaginal wall repair could be as a safety, cost-effective, minimal traumatic and durable procedure for recurrent POP in the most of cases.
