Objective To study the surgical diagnosis and treatment of renal tuberculosis(TB). Methods The clinical data of 42 cases with renal TB were analyzed retrospectively and the experiences of clinical diagnostic and treatment were summarized. Results Cystic irritation symptoms(78.6% ,33/42)and gross hematuria(64. 3%,27/42)were the most common symptoms in these patients. Abnormal urine were found in 83.3 % cases. Acid-fast stains on urinary sediment were positive in 28.6%(12/42)of cases. The diagnostic accuracy of B-ultrasonicgraphy,IVU,retrograde pyelography and CT examination in these patients were 19.0%(8/42),33.3% (14/42),26.2%(11/42)and 71.4%(30/42)respectively. Among all cases enrolled in the study,6 patients received antiphthisic medicine treatment,3 of them were cured and the other 3 accepted nephrectomy and partial ureterectomy after 6-12 months because of severe renal function impairment 36 cases received surgical treatment. In the 39 cases treated with operation,all of them were proved to carry renal tuberculosis by the postoperative pathological examinations. Conclusions The medical history,urine analysis,image examination should be considered synthetically in the clinical diagnosis of renal tuberculosis. The patients should be followed up closely during antiphthisic treatment period. Seriously damaged or nonfunctioning kidney should be removed promptly.

OBJECTIVE:To evaluate the effects of different doses of flurbiprofen axetil on analgesia effects of patients after laparoscopic cholecystectomy. METHODS:120 patients undergoing laparoscopic cholecystectomy were selected and randomly divid-ed into group A,B and C,with 40 cases in each group. Group A,B and C were given the mixture 100 ml of flurbiprofen axetil 100,150 and 200 mg combined with tramadol 600 mg and ondansetron 4 mg respectively and 0.9% Sodium chloride injection for patient controlled intravenous analgesia(PCIA)at the end of operation. Mean arterial pressure(MAP),heart rate(HR)and static and dynamic visual analogue scale(VAS)scores were observed in 3 groups at the end of operation,4,8,24 and 36 h after sur-gery. The incidence of incision pain,neck-shoulder pain and hypochondrium,the occurrence of ADR were recorded 36 h after oper-ation. RESULTS:After operation,There was no statistical significance in comparison of 3 groups with MAP,HR,static and dynam-ic VAS(P>0.05),4,8,24,and 36 h after operation,MAP,HR,static and dynamic VAS score of group B and C decreased sig-nificantly,there was statistical significance,compared with group A(P<0.05);there was no statistical significance in above indi-cators between group B and group C(P>0.05). After operation,the incidence of incision pain,neck-shoulder pain and hypochon-drium in group A were significantly higher than group B and C,with statistical significance(P<0.05),but there was no statistical significance between group B and group C(P>0.05). After operation,the incidence of ADR in group A and B were significantly lower than in group C,with statistical significance(P<0.05),but there was no statistical significance between group A and group B(P>0.05). CONCLUSIONS:Flurbiprofen axetil 150 mg combined with tramadol 600 mg and ondansetron 4 mg can improve he-modynamics and patient controlled intravenous analgesia in patients underwent laparoscopic cholecystectomy with lower incidence of ADR.

Objective To investigate the change of inferior vena cava pressure (IVCP) in type Ⅱ Budd-Chiari syndrome patients undergoing atrial caval shunting and its relationship with postoperative artificial blood vessel (ABV) patency rate.Methods We recruited 209 patients who had undergone atrial caval shunting for type Ⅱ Budd-Chiari syndrome and evaluated IVCP,right atrial pressure (RAP) and free portal vein pressure (PFP) before and after ABV opening.Presure changes were compared by t-test.These patients were followed up by color Doppler ultrasonograthy for ABV patency.The correlation between IVCP and postoperative ABV patency were analyzed By Kaplan-Meier test.Results IVCP (t =0.56,P ＜ 0.05)and PFP (t =0.72,P ＜ 0.05) decreased and RAP increased significantly after ABV opening (t =0.52,P ＜ 0.05).Follow up result showed that ABV patency rate was lower in patients with IVCP descent ＜ 1 kPa than those with IVCP descent ＞ 1 kPa (P ＜ 0.05).Conclusions Significant IVCP descent correlates with high ABV patency rate after atrial caval shunting in type Ⅱ Budd-Chiari syndrome patients.

Objective To investigate the influence of diameter of liver outflow vein on portal hypertension and artificial blood vessel (ABV) patency rate in Budd-Chiari syndrome (BCS) patients undergoing atrial caval shunting (ACS).Methods We recruited 209 patients,who had undergone ACS for Ⅱ type of BCS.Those patients with unobstructed liver outflow vein were included into group A and the patients with stenosed liver outflow vein into group B.Free portal pressure (FPP) was measured before and after ABV opening.Portal vein velocity (Vpv),liver function,spleen volume and function,esophagogastric varices and ABV patency were evaluated postoperatively.Results After ABV opening,FPP decreased significantly in group A than group B (t =10.45,P ＜ 0.05).Vpv accelerated significantly in group A 2 weeks after operation than group B (t =12.81,P ＜ 0.05).Apparent improvement of liver function,spleen function and esophagogastric varices and reduction of spleen volume were observed in group A patients than group B patients (P ＜ 0.05).Reduction of esophagogastric varices in group A was better than in group B (x2 =44.73,P ＜ 0.05).By postoperative follow up,ABV patency of group A was higher than group B (P ＜ 0.05).Conclusions Patency status of liver outflow vein significantly influences postoperative portal vein pressure and closely correlats to ABV patency rate after ACS.

ObjectiveTo analyze the relationship between expressions of Indoleamine 2,3-dioxygenase (IDO) and B7-H1 with clinico-pathological features and their prognostic significance in pancreatic cancer (PC).Method95 patients who underwent radical pancreaticoduodenectomy for PC were studied.The IDO and B7-H1 expressions in tissue specimens were determined by immunohistochemistry.ResultsIDO and B7-H1 expressions were higher in pancreatic carcinoma tissues than in normal pancreatic tissues (P＜0.05).IDO and B7-H1 expressions positively and significantly correlated with pathological grades and tumour-node-metastasis (TNM) stages (P＜0.05).They were prognostic of poor cancer-specific survival.After adjusting by the Cox proportional hazards regression models (P＜0.05),only a combined IDO/B7-H1 expression served as an independent prognostic marker.ConclusionsIDO and B7-H1 were expressed in PC,and they were important markers for malignant progression of PC.A combined IDO/B7-H1 expression served as an independent prognostic marker for PC.

Objective: To investigate the prognostic value of dynamic monitoring of RUNX1-RUNX1T1 transcript in pediatric patients with t (8;21) acute myeloid leukemia (AML) . Methods: The clinical features and RUNX1-RUNX1T1 transcript levels of 55 pediatric t (8;21) AML patients, newly diagnosed from Jan. 2010 to Apr. 2016, were analyzed retrospectively. The relationship between the minimal residual disease (MRD) and prognosis was analysed by dynamic monitoring of RUNX1-RUNX1T1 transcript levels using real-time quantitative PCR (RQ-PCR) technology. Results: The RUNX1-RUNX1T1 transcript levels in bone marrow cells at diagnosis was not related to relapse. After one course of induction therapy, patients with a more than 2 Log reduction of RUNX1-RUNX1T1 transcript levels (>2 Log) had lower 5 years cumulative incidence of relapse (CIR) [ (24.3±8.4) % vs (52.6±9.7) %, χ²=9.046, P=0.003], relapse-free survival (RFS) [ (71.6±12.7) % vs (48.1±13.2) %, χ²=5.814, P=0.016], and better overall survival (OS) [ (76.9±12.5) % vs (48.9±14.7) %, χ²=6.346, P=0.012], compared to patients with a less than 2 Log reduction (a<2 Log) . Multivariate Cox survival analysis suggested that a>2 Log reduction in RUNX1-RUNX1T1 transcript levels after a course of induction therapy was an independent prognostic factor for RFS (HR=0.263, 95%CI 0.081-0.851, P=0.026) and OS (HR=0.214, 95% CI 0.057-0.808, P=0.023) . During consolidation therapy and follow-up period, molecular relapse of 16 cases and hematologic relapse of 13 cases were identified by continuous dynamic monitoring of RUNX1-RUNX1T1 transcript levels, with a median interval of 4.0 (1.5-5.8) months from the molecular relapse to hematologic relapse. 2 cases of molecular relapse who received timely allogeneic hematopoietic stem cell transplantation did not experience hematologic relapse. Conclusion Dynamic monitoring RUNX1-RUNX1T1 transcript levels by RQ-PCR technique can subdivide patients into relatively low and high risk group, early screen patients at high risk of relapse and provide a scientific basis for precision stratification and risk-adapted therapy for pediatric t (8;21) AML children.

Objective:To investigate the association between plasma uric acid and hypertension and the gender difference in community-dwelling middle-aged and elderly population.Methods:A community-based cross-sectional study was conducted in Beijing Tongzhou Yongshun Community Health Service Center from June to December 2021, among residents aged 45 years or older selected by cluster sampling method. According to plasma uric acid (UA) level in quartiles, the subjects were divided into 4 groups; and stratified by gender, the subjects were further divided into subgroups. Multivariate logistic regression model was used to analyze the related factors of hypertension, and restricted cubic spline fitting logistic regression model was used to analyze the nonlinear association between uric acid and hypertension and the cut-off values of uric acid.Results:A total of 6 229 residents with the age of (63.2±7.3) years were enrolled in the study. In 1 874 male participants (30.1%), 946 participants (50.5%) had hypertension, and the uric acid level was 359 (309, 418)μmol/L; in 4 355 female participants (69.9%), 2 003 participants (46.0%) had hypertension, and the uric acid level was 306 (261, 359)μmol/L. Multivariate logistic regression analysis showed that after adjusting for factors that were statistically significant in univariate analyses or potentially clinically relevant (including age, body mass index, diabetes mellitus, coronary heart disease, cerebrovascular disease, albumin, estimated glomerular filtration rate, and cholesterol), uric acid was independently associated with hypertension ( P<0.001), for total participants the risk of hypertension in Q4 group was 1.33 times of that in Q1 group ( OR=1.33,95% CI 1.13-1.56, P=0.001); while for females the risk of hypertension in Q4 group was 1.38 times of that in Q1 group ( OR=1.38,95% CI 1.13-1.68, P=0.002), but no significant association was observed for males ( P>0.05). The results of restricted cubic spline fitting logistic regression analysis showed that there was a linear association between uric acid level and hypertension in the total population and males, and the risk of hypertension increased with uric acid level ( P<0.001 for the total population, P=0.016 for male). However, there was a non-linear association in females. When uric acid>307 μmol/L in females, the risk of hypertension increased significantly as the level of uric acid increased ( P<0.001). Conclusions:Uric acid level was independently associated with hypertension in the community-dwelling middle-aged and elderly population, and there was a gender difference in the correlation. The association was nonlinear in females and the cut-off value of uric acid in females was 307 μmol/L.

[Abstract] Objective: To observe the short-term efficacy and safety of Apatinib combined with radiotherapy and concurrent docetaxel and cisplatin chemotherapy in driver-gene-negative non-small cell lung cancer (NSCLC) patients with brain metastases. Methods: A total of 72 NSCLC patients with brain metastases, who were treated in our hospital from June 2018 to June 2019, were enrolled in this study. The driver gene was proved to be negative by next generation sequencing (NGS). The patients were divided into control group (36 cases) and treatment group (36 cases) by Digital random grouping method.The control group received 2 cycles of chemotherapy with docetaxel and cisplatin and concurrent radiotherapy for brain metastases, and the treatment group was given Apatinib anti-angiogenic treatment based on the regimen in control group. Primary study endpoints: confirmed objective response rate (cORR) and disease control rate (DCR); Secondary study endpoints: progression-free survival (PFS), quality of life (QOL) score, serum carcinoembryonic antigen (CEA), vascular endothelial growth factor (VEGF), and incidence of adverse drug events (AE). Results: Compared with the control group, cORR and DCR in treatment group were significantly improved [41.67% (15/36) vs 33.33% (12/36), 80.56% (29/36) vs 69.44% (25/36), all P<0.05], the median PFS was significantly prolonged (5.9 vs 4.6 months, P<0.05), and serum CEA and VEGF levels were significantly reduced [(16.5±2.3) vs (22.9±3.7) ng/ml, (291.6±42.6) vs (479.3±50.2) ng/L, all P<0.05], while the QOL score was slightly increased, but the difference was not statistically significant [(69.5±8.5) points vs (64.1±7.3) points, P>0.05]. There was no statistically significant difference in the incidence of acute brain edema, gastrointestinal reaction, bone marrow suppression, and liver dysfunction between the two groups of patients (all P>0.05); however, the incidences of oral mucositis, hand-foot syndrome, hypertension and proteinuria in the treatment group were significantly higher than those in the control group (all P<0.05). Conclusion: The efficacy of Apatinib combined with radiochemotherapy in driver-negative NSCLC patients with brain metastases is significantly better than that of radiochemotherapy alone, and the adverse reactions can be controlled. It is worthy of clinical recommendation.

OBJECTIVE: To evaluate the effectiveness of limited internal fixation combined with a hinged external fixator in the treatment of peri-elbow bone infection. METHODS: The clinical data of 19 patients with peri-elbow bone infection treated with limited internal fixation combined with a hinged external fixator between May 2018 and May 2021 were retrospectively analyzed. There were 15 males and 4 females with an average age of 44.6 years (range, 28-61 years). There were 13 cases of distal humerus fractures and 6 cases of proximal ulna fractures. All the 19 cases were infected after internal fixation of fracture, and 2 cases were complicated with radial nerve injury. According to Cierny-Mader anatomical classification, 11 cases were type Ⅱ, 6 cases were type Ⅲ, and 2 cases were type Ⅳ. The duration of bone infection was 1-3 years. After primary debridement, the bone defect was (3.04±0.28) cm, and the antibiotic bone cement was implanted into the defect area, and the external fixator was installed; 3 cases were repaired with latissimus dorsi myocutaneous flap, and 2 cases were repaired with lateral brachial fascial flap. Bone defects repair and reconstruction were performed after 6-8 weeks of infection control. The wound healing was observed, and white blood cell (WBC), erythrocyte sedimentation rate (ESR), and C-reaction protein (CRP) were reexamined regularly after operation to evaluate the infection control. X-ray films of the affected limb were taken regularly after operation to observe the bone healing in the defect area. At last follow-up, the flexion and extension range of motion and the total range of motion of the elbow joint were observed and recorded, and compared with those before operation, and the function of the elbow joint was evaluated by Mayo score. RESULTS: All patients were followed up 12-34 months (mean, 26.2 months). The wounds healed in 5 cases after skin flap repair. Two cases of recurrent infection were effectively controlled by debridement again and replacement of antibiotic bone cement. The infection control rate was 89.47% (17/19) in the first stage. Two patients with radial nerve injury had poor muscle strength of the affected limb, and the muscle strength of the affected limb recovered from grade Ⅲ to about grade Ⅳ after rehabilitation exercise. During the follow-up period, there was no complication such as incision ulceration, exudation, bone nonunion, infection recurrence, or infection in the bone harvesting area. Bone healing time ranged from 16 to 37 weeks, with an average of 24.2 weeks. WBC, ESR, CRP, PCT, and elbow flexion, extension, and total range of motions significantly improved at last follow-up ( P<0.05). According to Mayo elbow scoring system, the results were excellent in 14 cases, good in 3 cases, and fair in 2 cases, and the excellent and good rate was 89.47%. CONCLUSION Limited internal fixation combined with a hinged external fixator in the treatment of the peri-elbow bone infection can effectively control infection and restore the function of the elbow joint.

ObjectiveTo decipher the mechanism of Wenxiao powder in alleviating corticosterone-induced depression-like behaviors in mice. MethodMale ICR mice were randomized into normal， model， paroxetine （20 mg·kg^-1）， and low- and high-dose （3.27， 6.54 g·kg^-1， respectively） Wenxiao powder groups. The mice in normal and model groups received equal volume of saline. Other groups except the normal group were injected with corticosterone subcutaneously 0.5 h after gavage to induce depression. Mice were tested for depression-like behaviors after drug administration. Enzyme-linked immunosorbent assay （ELISA） was performed to measure the corticosterone content in the serum. Nissl staining was performed to observe the damage of hippocampal neurons. Immunofluorescence staining was employed to observe the expression of double cortin （DCX） in the dentate gyrus （DG） of the hippocampus. Western blot was employed to determine the expression of proteins in the brain-derived neurotrophic factor （BDNF）/tyrosine kinase receptor B （TrkB）/extracellular signal-regulated kinase （ERK）/cAMP-response element-binding protein （CREB） pathway in the hippocampus. ResultCompared with the normal group， the model group showed decreased sucrose preference rate， increased immobility time in the tail suspension test （P<0.01）， and reduced residence time in the central area of the open field and the total movement distance （P<0.05， P<0.01）. In addition， the modeling elevated the corticosterone level in the serum （P<0.01）， decreased the volume and intensified the nuclear staining of hippocampal neurons in the DG area， reduced the expression of DCX in the DG area， and down-regulated the protein levels of BDNF， phosphorylated （p）-TrkB， p-ERK， and p-CREB in the hippocampus （P<0.05， P<0.01）. Compared with the model group， low-dose Wenxiao powder improved the mouse behavivors in the sucrose preference， open field， and tail suspension tests （P<0.05， P<0.01）， and high-dose Wenxiao powder improved the behaviors in the sucrose preference and open field tests （P<0.05， P<0.01）. In addition， Wenxiao powder lowered the serum corticosterone level （P<0.01） and recovered the structure and morphology of neurons with obvious nuclei and presence of Nissl bodies in the DG area of the hippocampus. Moreover， Wenxiao powder at both doses promoted the expression of DCX in the DG area， and high-dose Wenxiao powder up-regulated the protein levels of BDNF， p-TrkB， p-ERK， and p-CREB in the hippocampus （P<0.05， P<0.01）. ConclusionWenxiao powder can alleviate corticosterone-induced depression-like behaviors and promote neurogenesis in mice possibly by activating the BDNF/TrkB/ERK/CREB signaling pathway.
