Objective To investigate the correlation between vitamin D receptor gene and bone mass and obesity phenotypes in patients with type 2 diabetes mellitus.Methods 318 patients with type 2 diabetes were chosen as diabetes group,and 50 healthy people were selected as healthy control group.Vitamin D receptor gene Apa Ⅰ type was detected in the two groups.Height,weight and body mass index(BMI)biochemical index,fat content(FM),lean tissue content(LM)and bone mineral density were detected in patients with type 2 diabetes mellitus.The relationship between vitamin D receptor gene(Apa Ⅰ)polymorphism and BMD and obesity phenotypes in type 2 diabetes was analyzed.Results The VDR gene distribution between the diabetes group and healthy control group showed no signif-icant difference(Z =0.561,P >0.05).The vitamin D receptor genotype in the diabetes group included AA 31 cases (9.7%),Aa type 108 cases(34.0%),aa type 179 cases(56.3%),while the vitamin D receptor genotype in the healthy control group comprised AA 7 cases(9.3%),Aa type 29 cases(38.7%),aa type 39 cases(52.0%).The percentage of AA in both groups was significantly less than that of Aa and aa(χ2 diabetic group =4.127,3.976,all P <0.05;χ2 healthy control group =5.129,4.213,all P <0.05).Proportion of normal bone mass and average bone density in AA,Aa,aa type decreased(χ2 =15.552,P <0.05;F =5.127,P <0.05),the genotype AA was not detec-ted in osteoporosis group.BMI and FM were the highest in AA,which were significantly higher than those of Aa,aa (F =4.319,4.263,all P <0.05).Conclusion Vitamin D receptor gene Apa Ⅰ type polymorphism is related with BMD and obesity in type 2 diabetes mellitus,and it has predictive value on bone mass changes.The increase of BMI and FMmay be beneficial to bone mineral density.

Objective To investigate the changes of monocyte chemoattractant protein-1(MCP-1)in serum and urine of lupus nephritis(LN)patients in active phase and remission phase.Methods The levels of MCP-1 in serum and urine of 58 LN patients(27 of active phase and 31 of remission phase)were measured by ELISA.The correlation between the levels of MCP-1 in variant phase of LN and other relevant factors were analyzed.Results The MCP-1 levels in sera of both active phase and remission phase of LN patients were markedly higher than those in controls(548.5?347.2 ng/L and 469.1?298.4 ng/L vs 273.3?146.7 ng/L,P0.05).Conclusion The MCP-1 levels in urine of LN patients is more suitable to evaluate the activity of disease as a sensitive marker.

Objective To investigate the protective effect and it's possible mechanism of Tanshinone ⅡA in radiation-induced pulmonary fibrosis.Methods Having the right hemithorax of female Wistar rats irradiated(30?Gy) in 10 fractions within 14 days by 6 ?MV photons,the radiation-induced pulmonary fibrosis animal model was established.In the treatment group,sodium Tanshinone ⅡA sulfonate(15?mg/kg) was given by intraperitoneal injection 1 hour before each fraction of irradiation.Five months after irradiation,the difference of the histopathological changes,the hydroxyproline content and expression of TGF-?1 between the radiation alone group,tanshinone plus radiation and control group were analyzed by HE stain,Massion stain,immunohistochemical methor and reverse transcriptase polymerase chain reaction(RT-PCR) method.Results The histopathological comparison revealed the protective effect of Tanshinone ⅡA.The content of hydroxyproline was(21.99?3.96),((38.25?)(7.18)),(28.94?4.29)??g/g in the control group,radiation alone group and radiation plus Tanshinone ⅡA.The expression of TGF-?1(mRNA and protein) was reduced by Tanshinone ⅡA.Pathological changes of the pulmonary fibrosis was reduced by Tanshinone ⅡA yet.Conclusions Our study shows that Tanshinone ⅡA can inhibit radiation-induced pulmonary fibrosis,and the possible mechanism of its may be made possible through down-regulating the expression of TGF-?1 in the irritated lung tissue.

Objective To evaluate the safety and efficacy of Voriconazole on invasive fungal infections in very elderly patients.Methods Clinical data of 24 very elderly patients with invasive fungal infections who had sought treatment at the Department of Geriatrics of our hospital from April 2013 to April 2014 were retrospectively investigated.The classifications and quantities of fungi,accompanying symptoms,adverse reactions,blood tests,and liver and kidney function indicators were recorded and analyzed before and after treatment.Results Each of the 24 cases was found to have been infected with one or more of 17 fungal strains belonging to the genus of Candida.The rate of complete fungal elimination after treatment was 70％ (12/17).Of the 24 cases,5 achieved a full recovery(20.8 ％),10 (41.7 ％) had significant improvement,5 (20.8 ％) had some improvement,and 4 cases(16.7％)showed no therapeutic benefits,with a total effectiveness rate of 62.5 ％.There was no significant difference in liver and kidney function before and after treatment(P＞0.05).A transient increase in serum creatinine occurred in 1 case and defective vision in another patient during Voriconazole treatment.Conclusions The incidence of invasive fungal infections is high in very elderly patients,with Candida as the main pathogen.Voriconazole is effective in treating invasive fungal infections in very elderly patients,and close monitoring of liver and kidney function is required during voriconazole treatment.

Objective To evaluate the relationship between fragile histidine triad(FHIT) transcription abnormalities and HPV16 infection and human cervical tumorigenesis.Methods Total RNA from 5 cervical carcinoma cell lines(SiHa,HeLa,RJC-1,CS1213 and C4-1),58 primary cervical cancer specimens and 18 normal cervical epithelial tissues were extracted and FHIT transcripts were characterized by a two-step(nested) reverse transcription(RT)-PCR.The seven of the PCR products with different size were purified and sequenced.HPV16 infection was assessed by PCR.Results ① There were altered FHIT transcripts in SiHa,HeLa and C4-1 cells.Aberrant FHIT transcripts were detected in 39 out of the 58 cervical cancer samples(67.2%),but none out of 18 in the normal cervix tissue specimens(0%);HPV16 infections were identified in 37 of the 58 cervical cancer tissues(63.8%),but 1 in the 18 normal cervical epithelial tissues(5%),which showed a significant difference between these two groups(P0.05).③ The exon 5 and exon 6 were mainly deleted in the altered FHIT transcripts and no insertion and point mutation were found by DNA sequencing.Conclusion Aberrant FHIT expression was significantly common in cervical cancers and was correlated with HPV16 infection.These findings suggest that the tumor suppressor gene FHIT and high risk HPV16 may play a very important role in human cervical carcinogenesis.

Methods A total of 128 patients underwent mini-cholecystectomy by using a modified Bookwalter retractor, a self-made deep-site tying tool and an L-shape electrotome from September 1998 to June 2003. Results That the length of incision ≤ 6 cm was regarded as a surgical success. Out of the 128 patients, the surgical success was achieved in 110 patients (85 9%). Conclusions In mini-cholecystectomy, the use of the modified Bookwalter retractor greatly improves the visualization of operation field, and the use of the self-made tying tool facilitates deep-site manual knot tying.

Objective To compare fentanyl and sufentanil in total intravenous anesthesia for liver resection. Methods 100 patients undergoing liver resection were randomly received either sufentanil (group S, n = 50) anesthesia or fentanyl (group C, n = 50). Hemodynamic variables, time to spontaneous eye opening and extubation were recorded. VAS-scale was used to assess postoperative pain. The incidence of nausea & vomiting, agitation and respiratory depression was recorded and compared. Results Patients in group S had a more stable hemodynamic variables, and the incidence of postoperative pain (VAS: group S 4. 2± 1.1, group C 6. 1 ± 1.2), agitation (group S 2 cases, group C 11 cases) and respiratory depression (group S 1 case, group C 5 cases)was lower. Conclusions Both sufentanil and fentanyl were safe and efficacious in total intravenous anesthesia for liver resection. Compared with fentanyl, Sufentanil had higher hemodynamic stability, and lower incidence of postoperative pain, respiratory depression and agitation.
