【Objective】To observe the therapeutic effect of lifting-pulling-rotating and oblique-pulling manipulation in treating lumbar interverbral disc herniation(LIDH).【Methods】A multi-center prospective control trial was carried out in 181 LIDH patients.The patients were randomized into two groups: group A(N=90)was treated with lifting-pulling-rotating and oblique-pulling manipulation,and group B(N=91)with traditional massage manipulations.Scores of symptoms and signs were examined to evaluate the therapeutic effect after 2-week treatment and after 3-month,6-month and 12-month follow-up respectivel in the two groups.Meanwhile,the changes of myoelectrogram were compared after treatment in the two groups.【Results】Evaluated by the symptoms scores,77(85.6%)patients were cured,10(11.1%)markedly effective and 3(3.3%)ineffective in group A after 2-week treatment,and 45(45.4%),32(35.2%)and 14(15.4%)respectively in group B,the difference being significant(P0.05).【Conclusion】The effect of lifting-pulling-rotating and oblique-pulling manipulation is better than that of traditional massage manipulations for lumbar interverbral disc herniation.

Objective To investigate the changes of IL-6, IL-10 and TNF-αafter cholecystectomy.Methods 46 cases with cholecystolithiasis were selected and divided into 2 groups.23 in control group were treated with open cholecystectomy, experimental group were treated with laparoscopic cholecystectomy.The levels of IL-6, TNF-α, IL-10 and CD4 +/CD8 +T were compared in the two groups pre-and post-treatment.ResuIts Compared with pre-treatment, two groups of patients with IL-10, TNF-α, IL-6 and CD4 +T and CD4 +/CD8 +T increased (P<0.05), compared with control group, experimental group IL-10, TNF-α, IL-6, CD4 +/CD8 +T levels were higher (P<0.05).ConcIusion Laparoscopic cholecystectomy can significantly reduce the IL-6, TNF-αand IL-10 levels, reduce the body′s stress response to surgery, and reduce blood flow, shorten the operation time.

Objective:To explore the value of preablative stimulated thyroglobulin (ps-Tg) in predicting distant metastasis (DM) at the time of 131I therapy in children and adolescents with differentiated thyroid cancer (DTC). Methods:From January 2016 to March 2020, 54 children and adolescents who underwent total thyroidectomy due to DTC in Peking Union Medical College Hospital were retrospectively reviewed and divided into 2 groups according to the presence of DM or not: M0 group( n=29, 10 males, 19 females, age (16.3±3.8) years) and M1 group( n=25, 13 males, 12 females, age (12.4±4.3) years). Independent-sample t test, χ2 test (or Fisher′s exact test) and Mann-Whitney U test were used to analyze the general characteristics between the two groups. According to status of regional lymph node (RLN) at the time of 131I therapy, the two groups were further divided into M1RLN+ ( n=8) and M1RLN-( n=17), M0RLN+ ( n=5) and M0RLN-( n=24) subgroups. Mann-Whitney U test was used to analyze the different ps-Tg levels between M0 and M1, M1RLN+ and M1RLN-, as well as M0RLN+ and M0RLN-groups. The receiver operating characteristic (ROC) curve analysis was employed to obtain a cut-off value of ps-Tg as a predictor of DM. Results:Patients with DM tended to have higher ps-Tg level (medians: 406.80 μg/L vs 7.90 μg/L, U=690.000, P<0.001), younger age ( t=-3.559, P=0.001), larger tumor size ( t=3.523, P=0.001), more advanced T stage ( U=506.500, P=0.010) and more multifocality( P=0.013) in comparison with those without DM. Though ps-Tg did not significantly differ between M1RLN+ group and M1RLN-group ( U=98.500, P>0.05) or between M0RLN+ group and M0RLN-group ( U=63.000, P>0.05), the two RLN+ groups tended to hold higher medians than the two RLN-groups (18.05 vs 5.71 μg/L; 1 698.50 vs 216.40 μg/L). In order to avoid the possible influence on the ps-Tg cut-off value, 13 RLN+ samples were removed, and the area under the ROC curve was 0.946 (95% CI: 0.883-1.000). The ps-Tg level of 55.87 μg/L was established as the optimal cut-off value to distinguish M0RLN- from M1RLN-, with the sensitivity and specificity of 14/17 and 95.8%(23/24), respectively. Conclusion:Ps-Tg holds a high predictive value in identifying DM, which may be of great help in avoiding inadequate 131I treatment in children and adolescents with metastatic DTC ignored by radiological examinations.

ObjectiveTo evaluate the factors implicated in the diagnosis and treatment of early gastric caner.Methods Fifty Patients early gastric caner with diagnosed from March 2004 to May 2006,were investigated in the study retrospectively.ResultsAll of the patients were diagnosed accurately by the gastroscopy,among which 2 had atrophic gastritis history for 6 or 10 years,respectively.Twenty-four masses were located in gastric pylorus,12 in gastic angular incisure,14 in gastric body.D2 radical mastectomy was performed in 41 cases,and D1 radical mastectomy in 9 cases.In 10 cases the diameter of tumors was ＜1 cm,17 cases 1 -2 cm,14 cases 2-3 cm,9 cases ＞3 cm.Lymph node involvements were observed in five cases ( 10％ ).Follow data were available in 48 cases.Among them,3 died from local recurrence and metastasis at postoperative 10,12,19 months respectively. Conclusions Although endosopic mucosal resection or limited surgical resection is a reasonable treatment for some early gastric caner patients,D2 radical mastectomy is necessary for most early gastric caner patients.

Objective To explore the clinical effect and side-effect of oxaliplatin(L-OHP)-containing regimen and cisplatin (DDP)-containing regimen in TACE of advanced hepatocellular carcinoma (HCC). Methods 108 patients with advanced HCC were randomly divided into experimental group(n=55) and control group (n =53). The experimental group were treated with TACE using L-OHP. After dilute with glucose solution, L-OHP(130 mg/m2) and FT207 (500-750 mg/m2) were injected into blood vessel respectively. ADM (40 mg/m2) and LP (10～30 ml) were emulsified and then used for vessel embolism according to the size of focus. The control group received TACE with DDP, DDP (40 mg/m2) and F]'207(500～750 mg,/m2) were diluted with glucose solution, and also according to the size of tumor' s focus, ADM(40 mg/m2) and LP(10～30 ml) were emulsified for vessel embolism, and then diuretic. Results The total effective rate of experimental group was 67.3 % (37/55), and that of control group was 47.2 % (25/53), and the difference was with statistical significance (P <0.05). The descent rate of AFP of experimental group was 73.1%(31/43), and that of control group was 44.7 % (17/38), and the difference was with statistical significance (P <0.05). The main side effects were gastrointestinal reactions, the incidence rate of nausea and vomiting in experimental group were lower than control group, and the difference was with statistical significance. The incidence rate of leucopenia, damage of hepatic function and peripheral neuritis were not significant. Damage of heart and kidney were not found in the two sets. Conclusion L-OHP -containing regimen in TACE of advanced HCC is an efficient method, with good security and good tolerance to patients.

This paper reports the establishment of a model of turbulent flow separation area for experiment on the downstream of tubal stenosis, and adjust it to cooperate with the velocity and turbulent shear stress (TSS) detection by means of the particle image velocimetry (PIV), and with the pressure detection of pressure sensor in vitro. The velocity, TSS and wall pressure characteristics of the downstream of tubal stenosis were quantitatively detected and analyzed via the PIV and pressure sensor. And the hydrodynamic characteristics of the velocity, TSS and wall pressure in the flow separation area were primarily understood. The model can cooperate smoothly with the PIV and pressure sensor to detect the velocity, TSS and wall pressure; there exist low velocity, low TSS and low pressure in the flow separation area downstream of tubal stenosis.

Objective To evaluate the clinical efficacy and safety of immunosuppression of calcineurin inhibitor monotherapy (AiCNIm)after alemtuzumab induction following renal transplantation.Methods Randomized control clinical trials related to application of AiCNIm (AiCNIm group ) and conventional triple regimes (Triple group ) for immunosupression after renal transplantation,published from 1 980 to December 31 201 4,were searched online from PubMed,Embase,Web of Science,Cochrance library and China National Knowledge Infrastructure (CNKI) databases.Meta-analysis was performed by Rev Man 5.2 software.Results Five randomized control studies consisting of 421 renal transplant recipients were included.The results of follow up for 6-1 2 months revealed that compared with the Triple group, the incidence of rejection response confirmed by acute rejection or aspiration biopsy in the AiCNIm group was significantly lower [relative risk (RR) =0.59,95% confidence interval (CI):0.40-0.89 ].However,there was no significant difference in the risk of renal allograft dysfunction (RR =0.85,95%CI:0.38-1 .87),death of recipient (RR =0.89,95%CI:0.30-2.67),infection (RR =1 .03,95%CI:0.91 -1 .1 7)and new-onset diabetes after transplantation (RR =0.62, 95%CI:0.29-1 .30)between two groups (all in P >0.05).Conclusions According to the existing evidence,application of calcineurin inhibitor monotherapy after renal transplantation exerts short-term immunosuppressive effect and high safety after alemtuzumab induction.

Objective:To evaluate the efficacy by using domestic recombinant human thyroid-stimulating hormone (rhTSH) in patients with differentiated thyroid cancer (DTC) before or after 131I therapy. Methods:From May 2019 to November 2020, a total of 24 patients with DTC (5 males, 19 females, median age 41 years) in Peking Union Medical College Hospital and Affiliated Tumor Hospital of Zhengzhou University were enrolled into the open-label, dose escalation phase Ⅰ study. All patients were divided into 4 domestic rhTSH dose groups: 0.9 mg×1 d (group A), 0.9 mg×2 d (group B), 1.8 mg×1 d (group C), 1.8 mg×2 d (group D) in succession, with 6 patients in each group. Each patient underwent rhTSH phase and thyroid hormone withdrawal (THW) phase. The end point included safety, tolerability, the quality of life (hypothyroidism symptom and sign score (Billewicz score), profile of mood states (POMS)), effectiveness (thyroid-stimulating hormone (TSH) and thyroglobulin (Tg) levels, diagnostic whole-body scan (Dx-WBS)) and pharmacokinetic characteristics (peak time, peak concentration) of rhTSH. Paired t test and Wilcoxon signed rank test were used for statistical analysis. Results:There were no dose-limiting toxicities, serious adverse events, or no grade ≥3 adverse events reported. The quality of life in rhTSH phase was significantly better than those in THW phase, including the lower Billewicz score (-53.00(-53.00, -53.00) vs -39.50(-47.00, -23.00); S=119.50, P<0.001) and the lower POMS score (91.92±12.06 vs 99.67±19.13; t=0.95, P=0.025). Serum TSH level was increased from 0.04(0.02, 0.11) mU/L (baseline) to 150.00(105.20, 173.31) mU/L 24 h after the last rhTSH administration, which was increased along with the elevation of rhTSH doses. In the THW phase, patients′ TSH levels were≥30 mU/L after 23 d (median) of THW, with the median of 73.51(57.22, 106.22) mU/L. Median Tg level of baseline was 0.10(0.10, 0.41) μg/L, which reached a peak of 0.85(0.12, 3.01) μg/L at 48 h after rhTSH administration. The peak Tg level in the THW phase was 0.88(0.15, 8.04) μg/L. The Dx-WBS consistency rate between rhTSH and THW phase was 95.8%(23/24). Conclusion:rhTSH is a safe and effective method to stimulate the serum Tg level and radioiodine uptake in patients undergoing post-operation or post- 131I assessment for DTC, as well as maintain a higher quality of life in comparison to THW phase.
