Objective To observe the clinical efficacy of bamboo-circled salt-partitioned moxibustion in treating arthritis of temporomandibular joint.Method Eighty patients were randomized into two groups. Forty cases in the bamboo-circled salt-partitioned moxibustion group received bamboo-circled salt-partitioned moxibustion at temporomandibular joint; forty cases in the warm needling group were intervened by selecting Xiaguan (ST7), Ashi point, etc. at the affected side. For the two groups, 3-day treatment was taken as a treatment course, and the therapeutic efficacy was analyzed after 2 treatment courses. The improvements in pain and mouth opening were observed before and after the treatment, and the treatment efficacy was evaluated by a 1-month follow-up study.Result The bamboo-circled salt-partitioned moxibustion group was superior to the warm needling group in comparing the real-time analgesic effect (P<0.05) and in the improvement of mouth opening (P<0.05); the comprehensive markedly effective rate was respectively 67.5% and 45.0% in the bamboo-circled salt-partitioned moxibustion group and warm needling group, and the between-group difference was statistically significant (P<0.05), indicating that bamboo-circled salt-partitioned moxibustion is better than warm needling in treating arthritis of temporomandibular joint; the follow-up study revealed satisfactory therapeutic efficacies in both groups: the effective rate was 92.5% in the bamboo-circled salt-partitioned moxibustion group versus 87.5% in the warm needling group, and the difference was statistically insignificant (P>0.05).Conclusion Bamboo-circled salt-partitioned moxibustion can produce a real-time analgesic effect and improve mouth opening; it's especially suitable to treat the patients who are afraid of needling, as it's significantly effective, safe, non-invasive,and easy-to-operate.

OBJECTIVETo measure uric acid of seminal plasma in fertile and infertile males.

METHODSOne hundred and sixty-three infertile males were divided into an obstructive azoospermic group (15 cases), a non-obstructive azoospermic group (36 cases), an oligozoospermic group (43 cases), and an asthenozoospermic group (69 cases). Twenty fertile males were included in the control group. Uric acid concentrations of seminal plasma in the fertile and infertile men were assessed by spectrophotometer, and sperm parameters were analyzed by computer-assisted semen analysis (CASA) system.

RESULTSUric acid concentration of seminal plasma in the control group was significantly higher than all the infertile groups (P < 0.01), and that of the obstructive azoospermic group significantly lower than the other infertile groups (P < 0.1), but no significant difference was observed among the other infertile groups (P > 0.05).

CONCLUSIONUric acid may play an important role in male reproduction because of its antioxidative property.

Objective:To study the relation ship between the branch patterns of inferior mesenteric artery (IMA) and imaging pelvic measurement parameters for anastomotic leakage (AL) after anterior resection (AR) of rectal cancer.Methods:Five hundred thirty-four patient were enrolled from Jan 2008 to Dec 2018 at the General Surgery Department of Guizhou Provincial People's Hospital. The AL related imaging risk factors were analyzed by chi-square test or Fisher's exact test.Results:AL was found in 36 (6.7%) patients. AL related mortality rate was 11.1% (4/36) compared to 0.4% (2/498) in those without the complications of no AL cases ( P<0.001). Seven pelvic imaging measurement results were attained in 412 patients including anteroposterior diameter of the inlet of the pelvis, anteroposterior diameter of the outlet of the pelvis, upper edge of the symphysis pubis to the tip of the coccyx, sacrococcygeal distance angle from the lower edge of the pubis to the upper edge of the pubis to the sacral promontory, distance between the ischial spines and that of ischial tuberosity. Univariate analysis showed that there was no significant relationship between the above 7 pelvic measurement parameters and the occurrence of AL (all P>0.05). There was no significant relationship between branch patterns of IMA and AL after rectal cancer surgery ( P=0.712). Conclusion:AL as a severe postoperative complication in rectal cancer patients undergoing AR procedure were caused by multiple factors. Neither IMA branch patters nor pelvic imaging measurement seem to be related to the occurrence of AL after AR for rectal cancer.

Objective:To analyze the clinicopathological features and prognostic factors of alpha‐fetoprotein‐producing gastric carcinoma (AFPGC).Methods:A retrospective analysis was made on 2 671 GC patients admitted from Jan 1998 to Dec 2018 , AFPGC patients and matching AFP negative GC cases were enrolled and their clinicopathological features and prognostic factors were analyzed. The survival curve was drawn by Kaplan-Meier method. Log-rank test was used to test the significance, Univariate analysis was performed by using COX proportional hazard model.Results:There were 98 AFPGC in this study accounting for 4.5% of all GC of the corresponding time period. The proportion of male to female was 2.16∶1, the average age was (65±12) years. The serum AFP levels significantly decreased after operation in most patients (median: 52 ng/ml vs. 5 ng/ml, Ｚ=-2.736, P=0.001). Serum AFP and CEA levels in patients with AFPGC before treatment were significantly higher than that in patients with AFP negative GC (both P<0.05) . Vascular invasion(62.71% vs. 40.68%) and liver metastasis (31.63% vs .6.12%) were more likely to occur in AFPGC groups (both P<0.05). However, there was no significant difference between the two groups in tumor size, location, differentiation and lymph node metastasis (all P>0.05). The prognosis of AFPGC was significant pooer than that in AFP negative GC ( P<0.05). Prognosis of AFPGC patients was significantly correlated with preoperative serum AFP level, TNM stage, lymph node metastasis, simultaneous liver metastasis and vascular invasion (all P<0.05) . COX multivariate survival analysis found that preoperative serum AFP level was independent risk factors of patients with AFPGC ( P<0.05). Conclusion:AFPGC is a special GC charactering poor prognosis .

OBJECTIVETo compare the safety and efficacy of the medial approach(MA) and the lateral approach (LA) in the treatment of colorectal disease.

METHODSStudies published from January 1994 to April 2013 that compared MA to LA in laparoscopic colorectal resection were collected. Publications in English were mainly identified from Medline, Embase, Cochrane Library, and those in Chinese from Wanfang database and CNKI database. Conversion rate, operative time, blood loss, number of harvested lymph nodes, hospital stay, complication, mortality, recurrence, and hospitalization costs of MA and LA were meta-analyzed using fixed-effect and random-effect models.

RESULTSFive cohort studies (2 randomized controlled trials and 3 retrospective studies) including 881 patients were enrolled and analyzed. Of these patients, 416 and 465 underwent laparoscopic colorectal resection with MA and LA respectively. As compared to LA, MA had significantly lower conversion rate (OR=0.42, 95%CI:0.25-0.72, P=0.001), shorter operative time (WMD=-52.62, 95%CI:-63.23--42.01, P<0.01), less number of harvested lymph nodes (WMD=-1.17, 95%CI:-1.89--0.45, P=0.001), while blood loss was less and hospitalization cost lower. Significant differences in intraoperative complications and postoperative complications were not found between the two group (OR:0.57, 95%CI:0.15-2.18, P=0.41; OR:0.78, 95%CI:0.52-1.17, P=0.23).

CONCLUSIONSCompared with LA, MA has the advantages of shorter operative time and lower conversion rate with similar safety. Differences in blood loss, hospitalization cost and oncological safety between the two approaches warrant further investigation.

Objective:To investigate the safety and efficacy of J-valve transapical catheter aortic Valve replacement(TA-TAVI) in the early treatment of aortic stenosis with low coronary ostium.Methods:From January 2020 to April 2022, 20 patients with aortic stenosis with coronary opening height ≤10 mm who underwent TA-TAVI treatment in the Valve Surgery Center of Beijing Anzhen Hospital Affiliated to Capital Medical University were enrolled retrospectively. All patients underwent preoperative imaging screening, and 5 patients underwent preoperative coronary artery protection: The height of coronary artery opening was less than 5 mm in 3 cases. 2 cases had stent stenosis & LT after coronary artery stenting 50%, and the position of the coronary artery opening was less than 8mm. The postoperative complications, mortality and cardiac function prognosis of TA-TAVI were analyzed.Results:There were 5 males and 15 females. The average age of the whole group was(73.00±6.20) years. Transthoracic echocardiography showed that all patients had severe aortic valve stenosis, and 85% of the patients had NYHA grade Ⅲ-Ⅳ, and 80% of the patients had aortic valve stenosis with insufficiency. The mean height of left coronary artery opening was(9.07±3.70) mm. RCA(11.39±3.00) mm; The opening height of coronary artery was ≤5 mm in 3 cases(left 7.5%), 5-8 mm in 5 cases(12.5%), and 8-10mm in 16 cases(40.0%). Mean aortic sinus(valsalva) diameter: Left(30.06±5.90) mm; Right(28.50±5.68) mm; Non(29.96±6.15) mm. J-valve Valve was successfully implanted through apical catheter in all patients, most of whom were size 23. CPB was performed in 2 patients at the same time, permanent pacemaker was inserted in 2 patients, and moderate or above perivalvular leakage was found in 0 patients. All patients had TNI( P=0.12) and MYO( P=0.03) before and 24 hours after operation. None of the 5 patients underwent coronary artery stenting. None of the 5 patients died within 30 days after the operation. Ta-tavi is effective 30 days after operation, with low complication rate and good prognosis of cardiac function. Conclusion:J-valve transapical catheter aortic Valve replacement is safe and effective in the treatment of aortic stenosis with low coronary ostium.
