ObjectiveTo compare the therapeutic effects of percutaneous cervical discectomy (PCD group),percutaneous cervical disc nucleoplasty(PCN) and the association of them (PCDN) for the treatment of cervical intervertebral disk displacement and instability of cervical vertebral column.Methods From February 2003 to April 2011,171 consecutive patients with cervical disc herniation have presented at the authors' hospital and were retrospectively studied.The average age of patients was 47.8 years(ranged,21-74).Ninety-seven cases were treated with PCD,50 cases with PCN,and the other 24 cases with PCDN.Clinical result and the stability of cervical vertebral column after operation were evaluated and compared among the 3 groups.ResultsAll cases had been followed up for a median of 4.1 years.There was significant difference in the pre- and post-operation the Japanese Orthopaedic Association(JOA) scoring system on within 3groups (PCD:t=21.85,P＜0.05; PCN:t=14.50,P＜0.05; PCDN:t=8.56,P＜0.05).All cases had been successfully operated.There was no significant difference between groups among the 3 groups in terms of the clinical outcomes(The recovery rate of JOA standard evaluation,F=2.19,P=0.12).According to Odom criteria,the excellent and good rate are as follows:81.35％ in PCD,82.44％ in PCN,83.19％ in PCDN,respectively.There was no significant difference between groups among the 3 groups in terms of the clinical success rate (P＞0.05).There was no instability of cervical vertebral column cases in 3 groups after operation(P＞0.05),and no significant difference was found in terms of cervical vertebral column stability in pre- and post-operation in each group.ConclusionAll the three operations including PCN,PCD and PCDN are safe,minimally invasive spine surgery for the treatment of cervical intervertebral disk displacement; they achieve good clinical outcomes and there are no difference on the stability of cervical vertebral column between preoperation and postoperation.

Objective To evaluate the intervention effects of systemic rehabilitation training on postoperative disuse shoulder dysfunction in hand injury patients received abdominal pedicled skin flap transplantation. Methods The 92 patients received same operation of abdominal pedicled skin flap surgery for unilateral hand in Hand and Foot Surgery Department of Provincial Hospital Affiliated to Shandong University and were divided into two groups, in which 45 patients as control group from March to April 2014 and 47 patients as experimental group from June to July 2014. The patients of control group received conventional therapy and nursing, while the ones of experimental group received systematic rehabilitation training by nurses and doctors before, during and after operation. Shoulder function was scored at the day 1 and day 7 after the pedicle division operation according to the shoulder joint function assessment scale, and we employed SPSS 20. 0 to analyze the results. Results The shoulder function scores of experimental group patients were (72. 96 ± 4. 72) and (87. 91 ± 4. 74) at the day 1 and day 7 after the pedicle division operation, which were better than the scores of control group patients, [(65. 11 ± 6. 74) and (79. 38 ± 7. 31)] (t =6. 492,6. 677;P <0. 01). Conclusions The systemic rehabilitation training program, which requirements were definite, and guidance was standard and easy to perform, can significantly improve the shoulder function of the patients received abdominal pedicled skin flap transplantation.

Background::Differentiated thyroid cancer (DTC) is commonly diagnosed in women of child-bearing age, but whether pregnancy influences the prognosis of DTC remains controversial. This study aimed to summarize existing evidence regarding the association of pregnancy with recurrence risk in patients previously treated for DTC.Methods::We searched PubMed, Embase, Web of Science, Cochrane, and Scopus based on the prespecified protocol registered at PROSPERO (CRD42022367896). After study selection, two researchers independently extracted data from the included studies. For quantitative data synthesis, we used random-effects meta-analysis models to pool the proportion of recurrence (for pregnant women only) and odds ratio (OR; comparing the risk of recurrence between the pregnancy group and the nonpregnancy group), respectively. Then we conducted subgroup analyses to explore whether risk of recurrence differed by response to therapy status or duration of follow-up time. We also assessed quality of the included studies.Results::A total of ten studies were included. The sample size ranged from 8 to 235, with participants’ age at pregnancy or delivery ranging from 28 to 35 years. The follow-up time varied from 0.1 to 36.0 years. The pooled proportion of recurrence in all pregnant patients was 0.13 (95% confidence intervals [CI]: 0.06-0.25; I2: 0.58). Among six included studies reporting response to therapy status before pregnancy, we observed a trend for increasingly higher risk of recurrence from excellent, indeterminate, and biochemically incomplete to structurally incomplete response to therapy ( Ptrend <0.05). The pooled risk of recurrence in the pregnancy group showed no evidence of a significant difference from that in the nonpregnancy group (OR: 0.75; 95% CI: 0.45-1.23; I2: 0). The difference in follow-up time (below/above five years) was not associated with either the proportion of recurrence in all pregnant patients ( P >0.05) or the OR of recurrence in studies with a comparison group ( P >0.05). Two included studies that focused on patients with distant metastasis also did not show a significant difference in disease recurrence between pregnancy and nonpregnancy groups (OR: 0.51 [95% CI: 0.14-1.87; I2: 59%]). Conclusion::In general, pregnancy appears to have a minimal association with the disease recurrence of DTC with initial treatment. Clinicians should pay more attention to progression of DTC among pregnant women with biochemical and/or structural persistence.Registration::PROSPERO, https://www.crd.york.ac.uk/PROSPERO/; No. CRD42022367896.

Objective To illustrate the clinical and pathological features of Chinese upper tract urothelial carcinoma (UTUC) patients and to investigate the regional difference and the possible prognostic factors.Methods A retrospective study was performed on 2 628 patients from 9 centers of three different regions (Beijing:2 centers with 1 022 cases,Shanghai:1 center with 814 cases,Sichuan:6 center with 792 cases).The median age was 68 (range 20 to 93) and the mean age was 66.3.There were 1 447 male patients (55.1％) and 1 181 female patients (44.9％).The clinical information,pathological outcomes and prognosis were collected and analyzed based on South (Shanghai and Sichuan) and North (Beijing)region.Results The distribution of Ta + T1,T2,T3 and T4 was 914 (34.8％),715 (27.2％),857(32.6％) and 142(5.4％).Patients from North were more likely to be female (55.9％ vs.38.0％,P＜0.001) and suffer from ureteral tumors (43.4％ vs.35.9％,P ＜ 0.001);while in patients from South higher tumor stage(T3 or T4,42.5％ vs.31.0％,P ＜ 0.001),high grade(72.0％ vs.34.0％,P ＜0.001) and larger tumor size [(3.73 ±2.17) cm vs.(3.36 ±2.02) cm,P＜0.001] were more prevalent.Subgroup indicated that female patients in North had obviously lower tumor stage (T3 or T4,27.2％ vs.35.9％,P =0.014),while relatively higher tumor stage were noticed in female patients in South (T3 or T4,48.2％ vs.38.9％,P =0.004).The median follow-up was 41 (1-206) months,and 963 patients (36.6％) died including 815 (31.0％) died from cancer.In North female patients had better 5-year overall survival (75.5％ vs.62.2％,P ＜0.001) and cancer-specific survival (78.3％ vs.65.0％,P＜0.001),but in South gender had no impact on overall survival (58.5％ vs.60.1％,P =0.927) or cancer-specific survival (62.0％ vs.65.8％,P =0.345).Conclusions This study demonstrated that in Chinese patients with UTUC,those from North were featured for lower tumor stage and grade,higher proportion of females and females had better survival.High age,high tumor stage and grade,large tumor diameter,and the presence of lymph node metastasis or lymphovascular invasion were risk factors for poor prognosis in Chinese UTUC patients.

Increased intestinal barrier permeability, leaky gut, has been reported in patients with autism. However, its contribution to the development of autism has not been determined. We selected dextran sulfate sodium (DSS) to disrupt and metformin to repair the intestinal barrier in BTBR T⁺tf/J autistic mice to test this hypothesis. DSS treatment resulted in a decreased affinity for social proximity; however, autistic behaviors in mice were improved after the administration of metformin. We found an increased affinity for social proximity/social memory and decreased repetitive and anxiety-related behaviors. The concentration of lipopolysaccharides in blood decreased after the administration of metformin. The expression levels of the key molecules in the toll-like receptor 4 (TLR4)-myeloid differentiation factor 88 (MyD88)-nuclear factor kappa B (NF-κB) pathway and their downstream inflammatory cytokines in the cerebral cortex were both repressed. Thus, "leaky gut" could be a trigger for the development of autism via activation of the lipopolysaccharide-mediated TLR4-MyD88-NF-κB pathway.
