Objective To observe the clinical effect of traditional Chinese medicine bone-setting technique using spinal,pelvi-lower extremity line to treat patients with knee osteoarthritis(KOA).Methods 426 patients with KOA were all from the First Affiliated Hospital of Hebei University of Traditional Chinese Medicine.They were randomly divided into experimental group(384 cases,57 cases of elimination,shedding and termination)by computer generated sequence.Traditional Chinese bone setting techniques were applied with spinal-pelvic-lower limb force line(divided into three parts:lumbar fixed point reduction method,hip joint push-pull and extension method and knee peripheral tendon recovery method every 3 days.2 weeks)treatment;The control group was the waiting treatment group(48 cases,6 cases were eliminated,abscission,termination),which was only used for clinical observation for 2 weeks.The main outcome index was WOMAC pain score.Secondary outcome measures were WOMAC stiffness score,functional score,standardized score and quality of life score(SF-12).The test time points were baseline,2 weeks after enrollment,and follow-up(14 weeks after enrollment).The control group was at baseline and 2 weeks after enrollment.Results Compared with baseline,WOMAC pain score,stiffness score,functional score and standardized score were all decreased in 2 groups 2 weeks after enrollment(P<0.05),but the experimental group was significantly decreased compared with the control group(P<0.001).SF-12 quality of life scores were all higher than before(P<0.001),but the experimental group was significantly higher than the control group(P<0.001).At follow-up,compared with 2 weeks after enrollment,WOMAC pain scores were increased(P<0.001),WOMAC stiffness,joint function and standardized scores were decreased(P<0.001),and SF-12 scores were increased(P<0.001).Conclusion The use of spinal-pelvi-lower extremity line of traditional Chinese medicine bone-setting technique in the treatment of KOA is effective in improving the knee joint function and improving the quality of life of patients,but the short-term effect of pain relief is good,and the long-term effect is not good.Its safety is good,and it can be considered in clinical application for KOA patients with joint dysfunction as the main manifestation.

Objective To investigate the occurrence of maternal stress under the epidemic, and analyze its relevant factors, to provide a reference for improving pregnancy quality and psychological counseling services during pregnancy. Methods From April to July 2020, 293 pregnant women from maternity and childcare hospital in Wuhan and Huanggang were selected as the subjects of the cross-sectional survey. Results The average score of the PSS pressure scale for pregnant women was (17.75±6.07), among which no/mild, moderate and severe stress accounted for 22.8%, 63.1% and 14.1%, respectively. According to multiple linear regression analysis, the factors affecting the maternal stress level of pregnant women are poor psychological resilience (β=-0.206, 95% CI: -0.288~-0.124), low family income (β=-0.370, 95% CI: -0.729~-0.012), excessively fearful about their babies (β=1.775, 95% CI: 0.640~2.910) and themselves (β=1.695, 95% CI: 0.625~2.766) about infected with the new virus. Conclusion The present study explores the factors related to maternal stress and depression during the epidemic. For pregnant women with high psychological stress, it is recommended that medical staff and family members should take care of them in a timely manner, strengthen their social support, and provide psychological counseling positively in order to improve pregnant women's psychological mood and promote maternal and infant health.

Objective:To evaluate the safety, efficacy and long-term survival of endoscopic submucosal dissection (ESD) for colorectal precancerous lesions and early cancer in the elderly over 80 years old.Methods:Clinical data of colorectal precancerous lesions and early cancer treated with ESD from January 2007 to December 2014 at Endoscopy Center of Zhongshan Hospital, Fudan University were retrospectively analyzed. A total of 721 patients with 778 lesions were included in this study. These patients were stratified by age: the super-elderly group (≥80 years old, 55 patients, 7.6%) and the non-super-elderly group (<80 years old, 666 patients, 92.4%). The outcomes of ESD, complication incidences, pathological characteristics, and long-term survival were compared between the two groups.Results:Except that the incidence of chronic concomitant diseases in the super-elderly group was significantly higher than that in the non-super-elderly group [54.5% (30/55) VS 31.5% (210/666), P<0.001], other baseline characteristics were not significantly different ( P>0.05). There were no significant differences in the complete resection rate [93.1%(54/58) VS 95.3%(686/720)], the R0 resection rate [89.7% (52/58) VS 93.2% (671/720)], the curative resection rate [84.5% (49/58) VS 90.3% (650/720)], the complication incidence [5.5% (3/55) VS 2.7%(18/666)], or the median hospitalization (2.98 days VS 2.54 days) between the two groups (all P>0.05). The three-year overall survival rates of the super-elderly group and non-super-elderly group were 95.8% and 98.0%, respectively, and the five-year overall survival rates were 85.1% and 97.4%, respectively. Conclusion:Colorectal ESD is safe and effective for elderly patients (age ≥80 years old) despite a significantly higher incidence of chronic concomitant diseases than that in the non-super-elderly patients.

Objective To evaluate the efficacy and safety of endoscopic balloon dilation (EBD) on treatment of benign colorectal anastomotic stenosis.Methods Data of 36 patients with benign colorectal anastomotic stenosis undergoing EBD at Zhongshan Hospital from 2011 to 2015 were reviewed retrospectively.The number of dilation,complications rate,short-term effects and recurrence rate of stenosis were analyzed.Results Thirty-six patients had post-surgery anastomotic stenosis within 2-49 months (median 6 months),including 10 (27.8％) patients of grade 1 stenosis,15 (41.7％) of grade 2 stenosis,and 11 (30.5％) of grade 3 stenosis.The anastomotic distance from anus was 3-24 cm (median 6 cm).The 36 patients underwent 80 times of EBD with mean time of 2.22.Among them,69.4％ (25/36) cases received 1-2 times and 30.6％ (11/36) received 3 times or more.During the EBD operation,14 (17.5％) patients had minor bleeding,and intraoperative or postoperative perforation did not appeared.Postoperative obstructive symptoms were relieved in all patients.The anastomotic diameter was greater than 20 mm and EBD treatment was successful.Postoperative follow-up was 22-76 months (median 44 months).Four (11.1％) patients had recurrence of anastomotic benign stenosis at 7,11,18,and 63 months after the last time of EBD,respectively,and the symptoms were improved after the second treatment.Conclusion EBD is safe and effective in treating benign colorectal anastomotic stenosis,with better short-term and long-term outcomes.

Objective: To evaluate the safety and efficacy of dental floss traction-assisted endoscopic submucosal dissection (DFS-ESD) for rectal neuroendocrine neoplasm (NEN). Methods: A retrospective cohort study was performed. Clinical data of rectal NEN patients undergoing ESD at Endoscopy Center of Zhongshan Hospital, Fudan University from January 2016 to December 2017 were retrospectively analyzed. Inclusion criteria: 1) age of 18 to 80 years old; 2) maximal diameter of lesions <1.5 cm; 3) tumor locating in the submucosa without invasion into the muscularis propria; 4) no enlarged lymph nodes around bowel and in abdominal cavity; 5) ESD requested actively by patients. A total of 37 patients were enrolled, including 23 male and 14 female cases with mean age of (56.0±11.3) years. All the lesions were single tumor of stage T1, and the mean size was 0.8±0.2(0.5-1.2) cm. Postoperative pathology revealed all samples as neuroendocrine tumors (NET). Seventeen patients received DFS-ESD treatment (DFS-ESD group) and 20 patient received conventional ESD treatment (conventional ESD group). In DFS-ESD group, after the mucosa was partly incised along the marker dots, the endoscopy was extracted, and the dental floss was tied to one arm of the metallic clip. When the endoscope was reinserted, the hemoclip was attached onto the incised mucosa; another hemoclip was attached onto normal mucosa opposite to the lesion in the same way. The submucosa was clearly exposed with the traction of dental floss and the resection could proceed. The conventional ESD group received the traditional ESD operation procedure. The operation time, modified operation time (remaining time after excluding the assembly time of dental floss traction in DFS-ESD group), en bloc resection rate, R0 resection rate, morbidity of operative complication, recurrence and metastasis were compared between two groups. Results: The average tumor size was (0.8±0.2) cm in DFS-ESD group and (0.7±0.2) cm in conventional ESD group (t=0.425, P=0.673). According to postoperative pathological grading of rectal neuroendocrine neoplasm, 13 were G1 and 4 were G2 in DFS-ESD group, while 17 cases were G1 and 3 cases were G2 in conventional ESD group without significant difference (P=0.680). There were no significant differences in baseline data between in the two groups (all P>0.05). All the basal resection margins were negative, the en bloc resection rate was 100% and the R0 resection rate was 100%. Pathological results showed tumor tissue close to the burning margin in 5 cases of conventional ESD group and in 2 cases of DFS-ESD group (P=0.416). The operation time was (17.9±6.6) minutes in conventional ESD group and (14.7±3.3) minutes in DFS-ESD group (t=1.776, P=0.084). The modified operation time of DFS-ESD group was (11.9±2.8) minutes, which was significantly shorter than (17.9±6.6) minutes in conventional ESD group (t=3.425, P=0.002). The hospital stay was (2.3±0.6) days and (2.0±0.5) days in conventional ESD group and DFS-ESD group, respectively, without significant difference (t=1.436, P=0.160). No patient was transferred to surgery, and no delayed bleeding or perforation occurred in either group. There was no recurrence or primary tumor-related death, and all the patients recovered well during a follow-up period of 14(1-24) months. Conclusion Dental floss traction-assisted ESD for rectal neuroendocrine neoplasm can simplify operation and ensure negative basal margin.

Objective To explore the feasibility, safety and effectiveness of endoscopic submucosal dissection ( ESD) in the treatment of the synchronous multiple early cancer or precancerous lesions in esophageal and stomach. Methods A retrospective study was conducted on the data of 5 patients with synchronous multiple early cancer or precancerous lesions in esophageal and stomach who were treated by ESD in Endoscopy Center of Zhongshan Hospital from January 2008 to December 2013. The characteristics of lesions, and results of therapy and follow-up were analyzed. Results All 5 patients were male with mean age of 67. 8±13. 1 years. The mean size of esophageal lesions was 2. 1±0. 9 cm with 1 lesion located in the upper esophagus and 4 in the middle. The mean size of gastric lesions was 2. 5±1. 5 cm with 2 lesions in the antrum, 2 in the gastric angle and 1 in cardia. Lesions in 4 cases were removed at the same time and 1 at different times. All lesions achieved complete resection. Postoperative pathological results showed that there were 2 cases of esophageal precancerous lesions with gastric precancerous lesions, 2 cases of esophageal precancerous lesions with early gastric cancer, and 1 case of early esophageal cancer with early gastric cancer. The 5 patients with 10 lesions all achieved curative resection. Postoperative esophageal stricture occurred in 1 case, which was improved after dilation. Median follow-up time was 72 months, when 3 patients survived and 2 patients died. However, the cause of death was not associated with the treatment. Conclusion ESD is a minimally invasive endoscopic method for treating synchronous multiple primary early cancers in esophagus and stomach.

Objective To explore the clinical value of dental floss traction-assisted endoscopic full-thickness resection ( EFTR) for muscularis propria tumor in gastric fundus. Methods Twenty-four patients with muscularis propria tumor in gastric fundus and undergoing EFTR with traction of dental floss from January to December in 2016 in Endoscopy Center of Zhongshan Hospital were enrolled in the trial group. Another 24 patients undergoing traditional EFTR from January to December in 2015 were enrolled in the control group. The control group was paired with the trial group according to tumor size. The differences in tumor resection time, hospitalization time, and complication rate were compared between the two groups. Results There were no significant differences in the mean age and gender composition between the two groups ( both P>0. 05) . The tumor resection time of the trial group was shorter than that of the control group ( 10. 8 ± 2. 8 min VS 19. 0 ± 4. 7 min, t = 7. 298, P<0. 05 ) . There was no significant difference in postoperative hospital stay between the two groups ( 3. 2 ± 0. 5 days VS 3. 2 ± 0. 5 days, t=0. 291, P=0. 772) . No postoperative delayed bleeding or perforation and other complications occurred in the two groups. Conclusion Dental floss traction-assisted EFTR is safe and effective to treatment of muscularis propria tumors in gastric fundus, which can expose the tumor boundary, so that the surgical level may be clearer to simplify the operation and reduce the tumor resection time.

With the rapid development of tumor subjects and the advance of medical technology,tumor mortality is declining in spite of the increase in tumor incidence.The male survivors pay more and more attention to their prognosis to improve the quality of their life.In the meantime,whether they could produce their own offspring become the main concern of tumor patients with good prognosis.However,until now,male tumor patients,their relatives,different social sectors and even some of our health workers,havent noticed the importance of fertility preservation and long-term fertility desires of male patients with tumor which will lead to declined or even irreversible sterility induced by the lack of fertility preservation before anti-tumor therapy.It's an important way to do fertility counseling,learn the risk of their treatment plans and choose the appropriate technique of fertility preservation which will improve prognosis quality of life of male tumor patients.This article will review the effects of tumor and the treatment on male fertility,their subjective needs and concerns,main methods for fertility preservation and the domestic and foreign research present situation.
