Objective:To investigate the role of survivin in the regulation of leptin expression and its sensitivity.Methods:Survivin was overexpressed in adipocytes via lentivirus, and the RNA-sequencing(RNA-seq) was used to explore the effect of survivin on the regulation of adipocyte secretory proteins. Survivin was overexpressed in the inguinal adipose tissue(iWAT) of mice by targeted injection of adeno-associated virus(AAV). The transcription levels of leptin and adiponectin were detected by realtime quantitative PCR(RT-qPCR), and the secretion levels of leptin and adiponectin in cellular supernatants and mice serum were detected by enzyme-linked immunosorbent assay(ELISA). The protein level of phosphorylated signal transducer and activator of transcription 3(STAT3) in hypothalamus was detected by Western blotting to investigate the effect of survivin on central leptin sensitivity.Results:Survivin overexpression in both 3T3-L1 and primary white adipocyte significantly down-regulated the leptin transcriptional expression without affecting the adipocyte differentiation( P<0.01). Overexpression of survivin significantly decreased leptin level without affecting the adiponectin levels in the cellular supernatant( P<0.001). Overexpression of survivin in iWAT via AAV injection, not only specifically down-regulated leptin transcriptional level in a dose dependent manner in local adipose tissue, but also led to a decrease in serum leptin level( P<0.05). In mice fed short-term high-fat diet, STAT3 phosphorylation level in hypothalamus significantly increased, suggesting improved central leptin sensitivity. Conclusion:Survivin could downregulate leptin expression and improve leptin sensitivity in high-fat diet induced obese mice.

Objective:To compare the effect of percutaneous screw-rod system combined with sacroiliac screw internal fixation and non-operation of type II-IV fragility fracture of the pelvis (FFP).Methods:A retrospective multicentral cohort study was performed to analyze the clinical data of 74 patients with FFP treated in Jiangjin Central Hospital of Chongqing and Hechuan People′s Hospital of Chongqing from January 2017 to June 2021, including 23 males and 51 females, aged 62-95 years [(79.3±7.3)years]. A total of 41 patients received non-surgical treatment (non-operation group). and 33 patients received percutaneous screw-rod system combined with sacroiliac screw internal fixation (operation group). The time to get out of bed, visual analog scale (VAS) and Majeed score on admission and at 1, 3, 6, 12 months after treatment, fracture healing time and complications were evaluated in the two groups.Results:Except for 9 patients who died at 3-9 months after treatment, the remaining patients were followed up for 12-24 months [(13.5±3.2)months]. The time to get out of bed was (11.4±2.8)days in operation group and was (67.4±4.4)days in non-operation group ( P<0.01). The VAS and Majeed score at 1, 3, 6 and 12 months after treatment were significantly improved in both groups compared with those on admission (all P<0.05). There was no significant difference in VAS and Majeed score between the two groups on admission (all P>0.05). The VAS was (3.2±0.7)points in operation group compared to (4.2±0.8)points in non-operation group at 1 month after treatment, and was (1.8±0.5)points in operation group compared to (2.9±0.7)points in non-operation group at 3 months after treatment (all P<0.01). The Majeed score was (56.0±2.4)points in operation group compared to (40.4±2.7)points in non-operation group at 1 month after treatment; the score was (77.3±2.6)points in operation group compared to (57.7±4.2)points in non-operation group at 3 months after treatment; the score was (86.5±1.8)points in operation group compared to (79.6±2.8)points in non-operation group at 6 months after treatment (all P<0.01). In contrast, the two groups had no statistically significant difference in VAS at 6 months and 12 months after treatment and Majeed score at 12 months after treatment (all P>0.05). There was no statistically significant difference in the fracture healing time between the two groups ( P>0.05). There was no statistically significant difference in the incidence of complications related to fixation methods between the two groups ( P>0.05). The incidence of bed-related complications was 24.2% (8/33) in operation group and was 51.2% (21/41) in non-operation group ( P<0.05). The 1-year fatality rate was 3.0% (1/33) in operation group and 19.5% (8/41) in non-operation group ( P<0.05). Conclusion:Compared with non-operative treatment, percutaneous screw-rod system combined with sacroiliac screw internal fixation in the treatment of type II-IV FFP can allow early off-bed movement, effectively relieve pain, improve quality of life of the patients, and reduce complication rate.

Objective:To analyze the in vitro inhibitory effects of resveratrol on rabies virus. Methods:The challenge virus standard (CVS)-11 strain of rabies virus and BHK-21 cells were used to establish the infection model. In vitro inhibitory effects of resveratrol on rabies virus were analyzed at different stages of infection by direct immunofluorescence and cell fluorescence focus unit assay. Results:Without affecting cell growth, resveratrol could block the adsorption of virus, interfere with the entry of virus into cells and inhibit virus proliferation in a concentration-dependent manner. The inhibition rate could reach up to about 95%. The results of co-incubation experiment showed that 40 μmol/L resveratrol could directly kill the virus.Conclusions:This study indicated that resveratrol inhibited the activity of rabies virus in a concentration-dependent manner.

Network Meta-analysis was used to compare the efficacy and safety of Chinese patent medicines in the treatment of unstable angina pectoris. PubMed, Cochrane Library, CNKI, Wanfang, VIP and other databases were retrieved by computers from the establishment of the databases to June 2020. Randomized controlled trials(RCTs) of Chinese patent medicines for the treatment of unstable angina pectoris were collected. Two investigators independently screened out the literatures, and extracted data according to the inclusion and exclusion criteria. The quality of the included RCTs was evaluated according to the bias risk assessment tool recommended by the Cochrane System Reviewer Manual, and the Stata 13.0 software was used for data analysis and mapping. Through screening, 28 eligible studies were finally included, with the sample size of 2 885 cases, involving 8 Chinese patent medicines. The results of the network Meta-analysis showed that in terms of total effective rate for angina symptom improvement, the order was as follows: Shenshao Capsules > Naoxintong Capsules > Ginkgo Ketone Ester Dripping Pills > Compound Danshen Dripping Pills > Ginkgo Leaf Tablets > Shexiang Baoxin Pills > Tongxinluo Capsules > Yindan Xinnaotong Soft Capsules; in terms of total effective rate for ECG curative effect, the order was as follows: Ginkgo Ketone Ester Dripping Pills>Compound Danshen Dripping Pills > Tongxinluo Capsules > Shenshao Capsules > Shexiang Baoxin Pills > Yindan Xinnaotong Soft Capsules; in terms of hypersensitivity-C-reactive protein curative effect, the order was as follows: Tongxinluo Capsules > Shenshao Capsules > Ginkgo Leaf Tablets>Compound Danshen Dropping Pills> Shexiang Baoxin Pills > Naoxintong Capsules > Yindan Xinnaotong Soft Capsules > Ginkgo Ketone Ester Dropping Pills. Chinese patent medicine combined with conventional therapy can improve the clinical efficacy of unstable angina pectoris. Due to the differences in the quantity and quality of the included studies, the order results of Chinese patent medicines need to be further verified.

BACKGROUND: Chronic soft tissue injury is easy to occur during daily living, sports training, treatment and rehabilitation of various acute and chronic diseases. Chronic soft tissue injury can cause pain. If there is no good treatment for the injured soft tissue, it is easy to develop limb dysfunctions (such as limited joint movements) due to have cicatricial contraction and adhesion, limited human activity and participation ability, affecting the quality of daily life activities. It can also reduce the effect of sports training or rehabilitation treatment for athletes and patients with various acute and chronic diseases. In recent years, the treatment of chronic soft tissue injury by instrument-assisted soft tissue mobilization has been widely concerned, which has a positive effect on pain relief after chronic soft tissue injury. This technology has been widely studied abroad, but less in China. OBJECTIVE: To summarize the progress of instrument-assisted soft tissue mobilization in the treatment of chronic soft tissue injury. METHODS: PubMed, WanFang, and CNKI were searched. Relevant literature concerning instrument-assisted soft tissue mobilization, chronic soft tissue injury and pain was retrieved and summarized. RESULTS AND CONCLUSION: Instrument-assisted soft tissue mobilization has a positive effect on the improvement of pain and joint limitation caused by chronic soft tissue injury. It has been proved that instrument-assisted soft tissue mobilization can also improve the soft tissue function of healthy people. Instrument-assisted soft tissue mobilization is suggested to be used in clinical treatment and sports training as a means of treatment and prevention. Current basic research on this technology is still insufficient. In the future, in addition to a large number of clinical randomized controlled studies, we should deeply explore its action mechanism to provide theoretical support for clinical application.

Objective: To evaluate the safety and efficacy of transurethral enucleation of bladder tumor(TUEBT) in the treatment of non muscle-invasive bladder cancer (NMIBC). Methods: The clinical and pathological data of 82 NMIBC patients treated between No-vember 2015 and January 2018 in the First Affiliated Hospital of the Jinzhou Medical University were retrospectively analyzed. The 82 NMIBC patients were divided into a TUEBT group (38 cases) and a transurethral resection of bladder tumor (TURBT) group (44 cases). The differences in intraoperative indices, postoperative indices, and pathological staging between the two groups were compared. Re-sults: The bladder irrigation, indwelling catheter, and postoperative hospitalization times in the TUEBT group were (21.00 ± 3.55) h, (4.34±0.81) d, and (5.29±0.96) d, respectively, compared with (27.57±3.87) h, (5.32±0.83) d, and (6.32±0.86) d in the TURBT group, and the differences between groups were statistically significant (P<0.05). The operative time in the TUEBT group [(29.55±4.13) min] was longer than in the TURBT group [(25.30±4.01) min]. The hemoglobin decrease in the TUEBT group [(2.00±0.38) g/dL] was less than that in the TURBT group [(2.30±0.32) g/dL]. The incidence of obturator nerve reflex in the TUEBT group was 13.16% (5/38), compared to 34.09% (15/44) in the TURBT group. The recurrence rate in the TUEBT group was 10.53% (4/38), compared to 29.55% (13/44) in the TURBT group. The detrusor deletion rate in the TUEBT group was 0 (0/38), compared to 31.82% (14/44) in the TURBT group. The re-peat transurethral resection (ReTUR) standard was met in 22 cases in the TUEBT group and 33 in the TURBT group. ReTUR due to lack of a detrusor was required in 0 cases in the TUEBT group and 14 in the TURBT group. The differences in the above clinical characteris-tics were statistically significant (P<0.05). Conclusions: TUEBT can remove a tumor completely, while preserving the detrusor, improv-ing the accuracy of pathological staging, and reducing the probability of ReTUR. For NMIBC, TUEBT can obtain satisfactory clinical effi-cacy, with surgical safety and long-term efficacy superior to those of TURBT.

Objective: To investigate the inactivating effect of soap solution on rabies virus and to explore the concentration of soap solutions which could be effective in post-exposure prophylaxis (PEP) of rabies virus infection. Methods: The BSR and N2a cells were respectively infected by the mixture of different concentrations of soap solution and rabies virus CVS-11. Based on the direct immunofluorescent method (DFA) and reverse transcription PCR (RT-PCR), the inactivating effects of soap solutions on rabies viruse in BSR and N2a cells were detected, respectively. Results: This experiment established the BSR or N2a cells model in 24 well cell culture plates, and we found that the upper limit of soap solution concentration which BSR or N2a cells could tolerate was 1%. The inhibitory effect test of different soap solution on rabies virus showed that the 0.5% concentration of soap solution could completely inhibit the survival of CVS-11 strain in both the BSR and N2a cells, but the 0.1% concentration of soap solution could not inhibit the rabies viruses completely. Conclusions The 0.5%-1% concentration of soap solutions could inhibit the survival of CVS-11 strain in three minutes in vivo experiment.

Objective To investigate the clinical efficacy of prucalopride in the treatment of severe chronic constipation.Methods The clinical data of 60 patients with severe chronic constipation [slow transit constipation (STC), functional defecation disorder (FDD) and constipation-predominant irritable bowel syndrome (IBS-C)] who were admitted to the Third Affiliated Hospital of Nanjing University of Chinese Medicine from February to August 2014 were prospectively analyzed.A prospective, clinical observational study was performed.Treatment plans included that patients withdrew the initial treatments of laxative and exema and took orally 2 mg prucalopride once daily for 2 weeks, and continued to be treated by oral prucalopride if frequency of the spontaneous complete bowel movement (SCBM) per week was satisfactory (or improvement of symptoms was more than 50％) till 4 weeks, and then were followed up after stopping prucalopride.If improvement of symptoms was less than 50％ after 2-week treatment, other treatment plans were performed according to symptoms of patients from week 3 to week 6 : (1) for patients with STC, prucalopride + two chain bacillus subtilis probiotic capsules were administered orally if patients were satisfied with frequency of SCBM per week and without improvement of abdominal distension;prucalopride + Chinese herb decoction were administered orally if patients had improvement of frequency of SCBM per week with abdominal distension or poor stool output;oral prucalopride + acupuncture were administered if patients were unsatisfied with frequency of SCBM per week or less bowel movements and without improvement of abdominal distension or poor stool output.(2) For patients with FDD, oral prucalopride + acupuncture + biofeed-back therapy were administered.(3) For patients with IBS-C, prucalopride + two chain bacillus subtilis probiotic capsules were administered orally if patients had abdominal distension;prucalopride Chinese herb decoction were administered orally if patients had improvement of frequency of SCBM per week and no improvement of abdominal distension or poor stool output.All patients used a diary for recording the frequency of SCBM per week, stool consistence, exertion in defecation and adverse reactions, which was submitted to doctors for inputting data at the return visit weekly.Results There was good overall medicine compliance in patients.Of 60 patients, 43 patients completed treatments (21 with STC, 11 with FDD and 11 with IBS-C).After 2-week treatment, there were 19 patients with satisfied therapeutic effects, 14 with improvement of constipation and 10 with poor therapeutic effects.After 4-week treatment, constipation in 17 patients was cured, constipation in 18 patients was improved,and constipation in 8 patients was not improved.Nineteen of 60 patients were complicated with adverse reactions within 1 week of the medication, including 6 patients dropping out of the trial due to medication withdrawal and others with improvement by symptomatic treatment or spontaneous remission.Conclusions Prucalopride is effective for the treatment of severe chronic constipation with a good toleration, and it can improve the overall satisfaction of patients combined with Chinese herb decoction and acupuncture.

We have assessed the relationships between immune trait (antibody titers of Sheep red blood cell, SRBC; Avian influenza, AI; Newcastle disease, ND) and varieties of MHC B-LBHII Gene in local chicken breeds (Wenshang Barred chicken, LH; Laiwu Black chicken, LWH; and Jining Bairi chicken, BR). We selected 300 chickens randomly from the three indigenous chicken populations. The variations of MHC B-L BII gene were detected by directly DNA sequencing and polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP). The results indicated that there were about 19-22 nucleotide mutations in the three local breeds, which could affect 16-18 amino acid variations. Another results indicated that there was significantly relationship between seven to eight SNPs of the MHC B-LBII region and some immune traits (P < 0.05 or P < 0.01). Both locus G97A and locus T138A were found in the three species, which were significantly related to the antibodies of SRBC, ND and AI antibody titers (P < 0.05). Among them, the locus G97A was significantly associated with ND antibody titers (P < 0.05) in BR chicken, with SRBC antibody titers (P < 0.05) in LWH chicken, and with H9 antibody titers (P < 0.05) in LH chicken. Furthermore, locus T138A was significantly associated with H9 antibody titers in BR and LH chickens (P < 0.05). All those results suggest relationships among the different varieties of MHC B-LBII and immune traits in the three local breeds.
