Objective To investigate the clinical characteristics on diagnosis and treatment of renal tubercu- losis.Methods Clinical data of 82 patients with renal tuberculosis were retrospectively reviewed.Results All of the 18 cases who received medication recovered completely.64 cases undergoing surgery were pathologically diagnosed to have renal tuberculosis,of which 2 cases developed ureteral stump syndrome.Conclusion Urine PCR-TB-DNA re- mained the primary diagnostic method before operation.Computed tomography(CT)and magnetic resonance urogra- phy(MRU)could be used in diagnosis of renal tuberculosis.When the non-functioning kidney was resected,per- inephrit fat and the involved ureter should be concomitantly resected as much as possible.

Objective To investigate the effect of sodium fluoride(NaF) on proliferation, differentiation and the mRNA expression of osteoprotegerin (OPG) and receptor activator of nuclear factor κβ ligand (RAN KL) of mouse osteoblasts. Methods Osteoblasts were isolated from calvarias of Kunming mice born in 1 - 2 d and cultured. Various concentrations of NaF(0, 10-8, 10-7, 10-6, 10-5, 10-4, 10-3mol/L) were added to the culture medium, the proliferation and activity of alkaline phosphatase(ALP) was determined after 72 h or 120 h. The expression of OPG mRNA and RANKL mRNA was analyzed by semi-quantification RT-PCR. Difference among groups was analyzed by One-Way AN0VA. Difference between two groups was analyzed by LSD-t test. Results There was significant difference in cell proliferation among groups after 72 h(F = 13.806, P < 0.05). Compared with control group(0.434 ± 0.010) , the proliferation was significantly induced in 10-7 - 10-4 mol/L groups treated osteoblasts (0.448 ± 0.010, 0.453 ± 0.013, 0.454 ± 0.016, 0.449 ± 0.018, all P< 0.05), and was significantly suppressed in 10-3 mol/L group(0.401 ± 0.009, P < 0.05). There was statistic difference in the activity of ALP among groups(F = 9.021, P < 0.05). Compared with control group (1.677 ± 0.682), the activity of ALP significantly increased in 10-7 - 10-5 mol/L groups[ (2.447 ± 0.756) × 106, (2603 ± 0.183) × 106, (2.687 ± 0.886) × 106 U/L, P < 0.05 or P < 0.01 ] and significantly decreased in 10-4 mol/L group[ (1.479 ± 0.366) × 106 U/L, P < 0.05 ]. There was significant difference in the expression of OPG mRNA among groups(F = 11.299, P< 0.05). Compared with control group (1.000 ± 0.000), the expression of OPG mRNA was significantly increased in 10-7 - 10-4 mol/L groups( 1.058 ± 0.027, 1.053 ± 0.026, 1.088 ± 0.055, 1.069 ± 0.008, P < 0.05 or P < 0.01) , while significantly decreased in 10-3 mol/L group (0.941 ± 0.029, P< 0.05). There was no difference in RANKL mRNA expression among groups (F= 1.311, P> 0.05). The ratio of RANKL/OPG decreased with increasing doses of fluoride and increased in 10-4, 10-3 mol/L groups, but there was no difference between groups(F = 1.376, P> 0.05). Conclusions A biphasic pattern of proliferation and differentiation has been induced in mouse osteoblasts, which manifests stimulation effect in low doses and suppression in higher doses. Low doses of sodium fluoride suppress differentiation and maturation of osteoblasts by increasing expression of OPG mRNA, while high doses of sodium fluoride enhance differentiation and maturation of osteoblasts by decreasing expression of OPG mRNA.

The equity in mental health resources allocated by geographical area was lower than that by population in Shanghai Municipality.

Objective To evaluate the performance of ELISA by detecting low quantitative HBsAg in serums.Methods 305 serum samples that the quantitation range was from 0.05 IU/ml to 9.99 IU/ml were collected,and then detected by ELISA. Results The rate of patients with low quantitation of HBsAg was 18.12% in patients with positive HBsAg.The total de-tected rate of ELISA was 87.87%,and the rate of 0.05~0.11,0.12~0.20,0.21 ~0.50,0.51 ~ 1.00,1.01~5.00 IU/ml and 5.01~9.99IU/ml were 36.00%,61.11%,78.38%,84.62%,99.11% and 100.00%,respectively.The differences were statistically significant between the detected rates of each group(χ2 =99.84,P =0.000).There was high correlation coeffi-cient between the results detected by ELISA and by CMIA(r = 0.874,P = 0.000).Conclusion The clinical laboratory should be careful to apply the method of ELISA to detect HBsAg for its missing detection in samples with low quantitation of HBsAg.

OBJECTIVETo find out an effective therapy for obesity induced by antipsychotic agents.

METHODSOne hundred and one cases of obesity who were being treated with antipsychotic agents were randomly divided into an observation group and a control group. The observation group were treated with electroacupuncture at Quchi (LI 11), Zusanli (ST 36), Fenglong (ST 40), Shangjuxu (ST 37) and Xiajuxu (ST 39), once a day for 8 weeks; and no treatment was given to the control group. The Brief Psychiatric Rating Scale (BPRS) was used for assessment of therapeutic effect and the Treatment Emergent Symptom Scale (TESS) for adverse effects.

RESULTSThe clinically effective rate of the observation group (54.9%) was superior to the control group (10.0%) with a significant difference between the two groups (P<0.05). The BPRS score-reducing rate was 24.92% and 28.62% in the both groups respectively, and with no adverse effects.

CONCLUSIONElectroacupuncture has a good therapeutic effect on obesity induced by antipsychotic agents, and it improves the patient's compliance with no adverse effect.

OBJECTIVE:To investigate the condition and characteristics of drug-induced liver injury (DILI) of anti-infective agents and provide reference for the prevention and treatment of anti-infective agents related DILI. METHODS:Based on retrospective analysis,a total of 572 DILI reports of anti-infective agents were collected from PLA ADR monitoring center during 2009 to 2013, and then analyzed statistically in terms of patient’s age and gender,main diagonosis,categories of DILI-inducing drugs,type,route of administration,occurrence time,lab indicator,DILI types and clinical manifestations,the application of liver protective drugs,out-comes,etc. RESULTS:Among 572 DILI cases,there were 412 cases(72.03%)of male patients and 160 cases(27.97%)of female patients,and average age of the patients was(44.54±23.75)years old. ADRs were related to 57 kinds of anti-infective agents in 6 cat-egories. Rifampin was the most frequent in suspected drugs,followed by isoniazid,moxifloxacin,fluconazole,azithromycin,cefurox-ime, cefoperazone/sulbactam, levofloxacin, cefoxitin and voriconazole. Intravenous infusion was the main administration route (74.48%). The occurrence time of ADRs was mainly within two weeks (86.19%). Hepatocellular damage (93.33%) was the main type in 360 cases of ADR for evaluation of liver injury types. The majority of cases(82.17%)were cured or improved after drug with-drawal and symptomatic treatment. CONCLUSIONS:Cephalosporin,fluoroquinolones,antituberculosis and antifungal drugs might be the common agents which caused liver injury. Hepatocellular damage is the most frequent type. Most of patients have a favourable prognosis. Clinical medical staffs should strengthen the awareness of DILI caused by anti-infective agents and ehance the prevetion of it.

OBJECTIVETo investigate the influence of early enteral immunonutrition on immunological function of body and intestine in severely scalded rats.

METHODSSixty-four healthy adult SD rats were subjected to 30% TBSA full-thickness scald and randomly divided into enteral nutrition group (EN, n = 32) and enteral immunonutrition group (EIN, n = 32). Another 8 healthy rats were enrolled as normal controls. The changes in CD3+, CD4+, CD8+ T lymphocyte subsets, the PCNA expression in intestinal mucosa,the amount of plasmocytes in lamina propria of small intestine and the content of s-IgA in small intestine were determined on 1, 4, 7 and 10 post-burn days (PBD).

RESULTS(1) CD3+, CD4+ and the ratio of CD4+/CD8+ were remarkably declined, while CD8+ was obviously raised after scald in EN group, and there were statistically significant differences at most of time-points when compared with those in control group (P < 0.05 or P < 0.01). CD3+, CD4+ and the ratio of CD4+/CD8+ on 7 and 10 PBD in EIN group were obviously higher (increased from 4 PBD on, and it was 1.86 +/- 0.25 on 10 PBD) than those in EN group (CD4+/CD8+ was 1.26 +/- 0.10 on 10 PBD), while CD8+ in EIN group was evidently lower than that in EN group (P < 0.01). (2) The level of PCNA expression in intestinal mucosa, the amount of plasmocytes in lamina propria of small intestine and the content of s-IgA in small intestine in EIN group were increased significantly compared with EN group on 4, 7, 10 PBD (P < 0.05 or P < 0.01).

CONCLUSIONEarly enteral immunonutrition can improve immunological function of body and intestine after severe scald, with better results than enteral nutrition.
