Objective: The relationship of antipsychotics and the risk of refracture in treated patients is unclear. The aim of this study is to evaluate the association between prolonged antipsychotic and the incidences of bone fractures and refractures in schizophrenia. Methods: This is a retrospective nested case-control study using Taiwan National Health Insurance Research Database recorded from 2000 to 2005, with cases followed up to end of 2011. Total of 7,842 schizophrenic patients, 3,955 had developed bone fractures were compared with 3,887 control subjects matched in age, sex, and index date.Antipsychotic drug exposure was classified based on the drug type and medication duration. Conditional logistic regression analyses were performed. Odds ratio (OR) and confidence interval (CI) were calculated. Results: We found (after adjustments) higher risks of developing fractures under continued use of typical (OR = 1.70; 95% CI, 1.51−1.91) or atypical antipsychotics (OR = 1.43; 95% CI, 1.28−1.60) were found. Additionally, continued use typical (OR = 1.84; 95% CI, 1.35−2.50) or atypical antipsychotics (OR = 1.44; 95% CI, 1.06−1.95) was positively associated with refracture risks. Moreover, refractures were associated with continuous use of chlorpromazine (one typical antipsychotics, OR = 2.45; 95% CI, 1.14−5.25), and risperidone (OR = 1.48; 95% CI, 1.01−2.16) or zotepine (OR = 2.15; 95% CI, 1.06−4.36) (two atypical antipsychotics). Conclusion Higher risks of bone fracture and refracture were found in schizophrenia under prolonged medication with typical or atypical antipsychotics. We therefore recommend that clinicians should pay more attention on bone density monitoring for patients using long-term antipsychotics.

OBJECTIVETo observe the anti-renal fibrosis effect of Paidu Baoshen Pill (PBP) on 5/6 nephrectomized rats and to explore its mechanism.

METHODSTotally 50 SD male healthy rats were randomly divided into the normal control group (n = 10), the sham-operation group (n = 10), and the nephrectomy model group (n = 30) according to the proportion of 1:1:3. Rats in the sham-operation group had their renal capsule isolated without nephrectomy. Rats in the nephrectomy model group had their kidneys 5/6 nephrectomized. Then 24 h urine was collected and 24 h urinary protein (24 h UP) detected. Serum blood urea nitrogen (BUN) and serum creatitine (SCr) were also tested. According to the SCr level 30 rats of the model group were further randomly divided into the model group, the PBP group, and the Niaoduqing Granule (NG) group, 10 in each group. Rats in the PBP group and the NG group were respectively administered with PBP (at the daily dose of 1.0 g/kg) and NG (at the daily dose of 3.33 g/kg) by gastrogavage (they were dissolved in distilled water). At the same time, 2 mL distilled water was administered by gastrogavage to rats in the normal control group, the sham-operation group, and the nephrectomy model group, once daily for 4 successive weeks. Mental conditions, activities, hair color, shape of stool, and the body weight were observed during administration. After 4 weeks, urine was collected to detect 24 h UP. Blood was sampled to detect SCr, BUN, transforming growth factor β1 (TGF-β1), type III procollagen (PC III), collagen type IV (Col IV), laminin (LN), and fibronectin (FN). After rats were killed, their left remnant renal tissues were collected for pathological examinations. The protein expression quantity of TGF-β1 and FN was detected by immunohistochemical method. mRNA expression levels of TGF-β1 and FN were detected using real time fluorescent quantitative PCR.

RESULTSThere was no statistical difference in the above indices between the normal control group and the sham-operation group (P > 0.05). Compared with the sham-operation group, rats' general condition was poorer in the model group, their body weight grew slower, and 24 h UP increased; serum levels of BUN, SCr, TGF-β1, PC III, Col IV, LN, and FN increased; the residual renal pathological lesion was serious; expression levels of TGF-β1, TGF-β1, mRNA, FN, and FN mRNA increased in the renal tissue (all P < 0.01). Compared with the model group, rats' general condition was better, their body weight grew faster, 24 h UP reduced (P < 0.05), blood levels of BUN and SCr decreased significantly (P < 0.01), serum levels of TGF-β1, PC III, CoL IV, LN, and FN decreased (P < 0.05, P < 0.01); the residual renal pathological lesion was attenuated in the PBP group and the NG group; expression levels of TGF-β1, TGF-β1, mRNA, FN, and FN mRNA decreased (P < 0.01). Compared with the NG group, blood levels of SCr and FN, and expression levels of FN and FN mRNA decreased more in the PBP group (P < 0.05).

CONCLUSIONSPBP had the effect of anti-renal fibro- sis in 5/6 nephrectomized rats. Down-regulating expression levels of TGF-β1, and FN from gene transcription and protein translation levels might be one of its mechanisms.

OBJECTIVETo investigate the effect of preoperative radiotherapy or chemoradiotherapy on the sphincter preservation and local tumor control as well as survival for the patient with locally advanced middle-low rectal cancer.

METHODS121 locally advanced middle-low rectal cancer patients were treated with preoperative radiotherapy or chemoradiotherapy followed by surgery after rest of 4 to 6 weeks. 103 of these patients who underwent radical surgery were finally included in this study. The irradiation regimen was: 40 Gy/4 - 5 weeks, whereas 57 of these 103 patients received concurrent chemotherapy of 5-Fu or Xeloda. Sphincter-preserving surgery was performed in 59 patients and abdominoperineal resection in 44 patients. The survival was estimated by Kaplan-Meier model, and the differences between groups were compared using Log rank test. Multivariate analysis was performed by Cox's model.

RESULTSTen patients (9.7%) achieved a complete pathological response (pCR) to preoperative radiotherapy or chemoradiotherapy. The sphincter preservation rate was 57.3%. The 3-year overall survival (OS) and disease free survival (DFS) was 66.3% and 59.5%, respectively. Univariate analysis showed that pCR and postoperative pTNM stage were prognostic factors affecting survival, whereas, only pTNM stage was an independent prognostic factor (P = 0.003) by multivariate analysis.

CONCLUSIONNeoadjuvant preoperative radiotherapy and chemoradiotherapy is effective in local tumor control and improving survival for locally advanced middle-low rectal cancer, which can raise the rate of sphincter-preserving surgery, and achieve comparable result to abdominoperineal resection.

Objective To explore the effects of p53 up-regulated modulator of apoptosis (PUMA)-α protein on the apoptosis and fibrosis of human peritoneal mesothelial cells (HPMCs) induced by high glucose.Methods HPMCs were induced by 50mmol/L D type glucose or mannitol for 72 hours respectively,flow cytometry was employed to detect the rate of apoptotic cells,and theexpression levels of apoptosis-and fibrosis-related proteins were detected by Western blotting.The untreated HPMCs were transfected with Lenti-PUMA-α,and the treated cells were transfected with shRNA-PUMA-α,the number of apoptotic cells and the expression levels of apoptosis-and fibrosis-related proteins were detected with the methods mentioned above.Results Flow cytometry showed that the rate of apoptotic HPMCs increased after being induced by high glucose for 72 hours,and Western blotting revealed that the expression levels of pro-apoptotic and pro-fibrotic related proteins increased,but the arrestins of apoptosis and fibrosis-related proteins decreased.Up-regulation of PUMA-α promoted apoptosis and fibrosis,while down-regulation of PUMA-α alleviated apoptosis and fibrosis of HPMCs.Conclusion High glucose may accelerate apoptosis and fibrosis of HPMCs by up-regulating the expression of PUMA-α.

Objective:To establish a new molecular typing method for Treponema pallidum (TP) based on TP0136 protein sequence heterogeneity. Methods:The amino acid sequences of TP0136 open reading frame (ORF) of 9 strains of Treponema pallidum ssp. Pallidum (TPA) , 3 strains of Treponema pallidum ssp. Pertenue (TPE) , 1 unclassified simian strain of Treponema Fribourg-Blanc (FB) and 1 strain of Treponema pallidum ssp. Endemicum (TEN) were searched from Genbank, and multiple sequence comparisons were performed to obtain the molecular typing results of TP0136 protein. The TP0136 protein-based molecular typing method was used to classify 23 TPA clinical isolates, which were collected from Dermatology Hospital of Southern Medical University from January 2015 to December 2018, and the typing results were compared with those by the traditional typing method based on the tp0548/Arp/Tpr genes. Results:TP0136 protein was highly heterogeneous in different TP strains. According to the amino acid sequence of TP0136, TPE, FB and TEN strains were divided into 4 subtypes of Ⅰ- Ⅳ, TPA strains were divided into 6 subtypes of Ⅴ-Ⅹ, and TPA clinical strains were classified into 4 subtypes of Ⅶ, Ⅸ, Ⅹ, Ⅺ. Through the traditional typing method described above, 23 TPA clinical strains could be divided into 5 types (13D/d, 14D/f, 14D/g, 15D/f, 16A/e) . By using the TP0136 protein-based typing method combined with traditional typing method, the above clinical strains could be further subdivided into 10 types, and the 14D/f type could be further divided into 3 subtypes by using the TP0136 protein-based typing method.Conclusion:The TP0136 protein-based molecular typing method can be used to distinguish TP species, which is helpful for further improvement of traditional TPA molecular typing.
