Objective To clone human beta-2 adrenoceptor gene from human bladder smooth muscle and to construct its antisense eukaryotic expression vector. Methods The ?_2-AR full length cDNA was cloned from human detrusor cells through RT-PCR and subcloned into clone vector (pUC18).The objective gene was then cut from ClaⅠ/HindⅢ sites of pUC18 with restriction endonulcease and subcloned into pLNCX vector in trans-direction.Finally the constructed ?_2-AR gene antisense expresstion vector was identified through restriction endonuclease analysis and sequencing. Results The sequence of cloned ?_2-AR full length cDNA was certified by comparison with the database of the Genebank.The constructed antisense eukaryotic expression vector was proved to be same with designed by restriction endonuclease analysis and sequencing. Conclusions ?_2-AR full length cDNA was cloned and its antisense eukaryotic expression vector was successfully constructed.This technique establishs the foundation for the further research on drug treatment of bladder dysfunction.

Objective To explore the influence of hyperbaric oxygen(HBO)on the life-spans of tumor-bearing mice. Methods Twenty-eight male Balb/c mice were randomly and evenly divided into:a celiac-tumorgroup(inoculated with tumor cells in the abdominal cavity);a celiac-tumor-HBO group(inoculated and then ex-posed to hyperbaric oxygen);a back-tumor group(inoculated under the skin of the back);and a back-tumor-HBOgroup(inoeulatedunder the skin of the back and then exposed to hyperbaric oxygen).S-180 carcinoma cells were in-oeulated,and then HBO was administered once a day.The life-spans and any skin ulceration were observed. Re-sults The average life-spans were(27.6±4.5)days in the celiac.tumor group,(24.0±2.9)days in the celiac-tumor-HBO group,(63.0±21.8)days in the back.tumor group and(35.0±8.9)days in the back-tumor-HBOgroup.The difference in average life-span between the celiac-tumor group and the celiac-tumor-HBO gmup was not significant.The difference in life-span between the back-tumor group and the back.tumor.HBO group was significant.Ulcers occurred in 4 mice in the back-tumor group and 4 in the back-tumor-HBO group.The times of ulcer formation were significantly different between the back-tumor group and the back-tumor-HBO group. Conclusions The life-spans of mice in the back-tumor-HBO group were shortened by HBO exposure,but life-spans in celiac-tumor-HBOgroup were not.Ulcer formation was postponed by HBO in the back-tumor-HBO group.

Objective To explore the cause and effective management and prevention of septic shock after minimally invasive percutaneous nephrolithotomy (MPCNL) in the elderly.Methods Clinical data of 13 patients with septic shock after MPCNL in our hospital were retrospectively analyzed,and the cause,prevention and treatment of septic shock were investigated.Results The incidence of septic shock in patients undergoing MPCNL was 3.54％ in this study.Single-factor analysis and logistic regression analysis showed that the risk factors for post-MPCNL septic shock were female and the history of diabetes (both P＜0.05).Conclusions Septic shock is a serious complication after MPCNL.Intensive perioperative prevention measures can reduce the incidence of septic shock.Early diagnosis and proper treatment are the keys to successful treatment of septic shock.

The incidence of venous thromboembolism in patients with ovarian cancer is much higher than other gynecologic cancers. Approximate 20%of ovarian cancer patients have hypercoagulable status during different phases of their disease. Ovarian cancer itself can induce hypercoagulability, but meanwhile the over activated coagulation system may promote disease progression. Coagulation system disorder is one of the most important prognostic factors in ovarian cancer. Recently, hypercoagulability becomes a hot spot in the ovarian cancer research ifeld. This article reviews the mechanism of hypercoagulability, its clinical implication and correlated treatment in ovarian cancer patients.

Objective To explore the clinical value of glycosylated hemoglobin A1(HbA1c) ,C-reactive protein(CRP) ,interleu-kin-6(IL-6) and ischemia modified albumin(IMA) in patients with type 2 diabetes nephropathy .Methods 64 patients with type 2 diabetes mellitus were divided into simple diabetic mellitus group(34 patients) and diabetic nephropathy group(30 patients) .In ad-dition ,40 healthy subjects were chosen as control group .The levels of HbA1c ,CRP ,IL-6 and IMA were detected .Results The lev-els of HbA1c ,CRP ,IL-6 and IMA in simple diabetic mellitus group were all significantly higher than those in control group(P<0 .05) .The levels of HbA1c ,CRP ,IL-6 and IMA in diabetic nephropathy group were all significantly higher than those in simple di-abetic mellitus group(P<0 .05) .There were a positive correlations between the HbA1c level and the levels of CRP ,IL-6 ,IMA(P<0 .05) .The positive rate of combined detection of HbA1c ,CRP ,IL-6 and IMA was significantly higher than separate index detection (P<0 .05) .Conclusion The combined detection of HbA1c ,CRP ,IL-6 and IMA may be beneficial to the early diagnosis of diabetic nephropathy ,which will delay the progress of diabetic nephropathy .

Objective To study risk factors with the occurrence of the mesh exposure after pelvic floor reconstruction.Methods From Mar.2007 to Mar.2011,a retrospective study was made on the clinical data of 353 patients undergoing vaginal mesh pelvic floor reconstruction.The related complications of the mesh were surveyed,and risk factors associated with the mesh's exposure were studied by single factor and multiple factors logistic regression.Results It was found that the exposure rate was 9.6％ (34/353) after 1 year postoperative follow-up.Single factor analysis showed that patients who were not less than 70 years old,patients who were on their menopause stage,the occurrence of not less than three parturition,history of pelvic surgery,diabetes and smoking had a significant correlation (all P ＜ 0.05) with the occurrence of the mesh exposure after pelvic floor reconstruction.Multiple factors logistic regression analysis showed that patients who were not less than 70 years of age (OR =2.389),the occurrence of not less than three parturition (OR =2.688),the history of diabetes (OR =3.545),the history of pelvic surgery (OR =5.385) were the independent risk factors,and the operation experience was the protection factors (OR =0.134).Conclusions Mesh exposure is a common complication after pelvic floor reconstruction.Old age,multiple delivery,history of diabetes and history of pelvic surgery are the risk factors of mesh exposure.Preoperative full assessment and the quality of training contribute to reduce the incidence.

Objective:To investigate the expression of solute carrier family 35 member E1 (SLC35E1) and SLC35E2B in skin lesions of patients with Mycobacterium infections. Methods:Paraffin-embedded skin tissues of 31 patients confirmedly diagnosed with Mycobacterium infections were collected from Dermatology Hospital of Southern Medical University from 2014 to 2018, including 10 cases of multibacillary leprosy, 9 of nontuberculous mycobacterial infection, 7 of cutaneous tuberculosis, and 5 of erythema induratum. Meanwhile, paraffin-embedded skin tissues of 10 healthy individuals were collected, and served as normal control group. Immunohistochemical staining was performed to determine the expression of SLC35E1 and SLC35E2B in the lesional and normal control skin specimens, and immunofluorescence staining to observe the co-expression of CD68 and S100 with SLC35E1 and SLC35E2B in the skin lesions. Results:Neither SLC35E1 nor SLC35E2B was expressed in the normal control group, but high expression of SLC35E1 and SLC35E2B was observed in the dermis of skin lesions from the patients with leprosy, nontuberculous mycobacterial infection, cutaneous tuberculosis or erythema induratum. Immunohistochemical staining showed that the expression of SLC35E1 and SLC35E2B (expressed as average optical density) was significantly higher in the multibacillary leprosy group (0.143 ± 0.010, 0.169 ± 0.004, respectively) , nontuberculous mycobacterial infection group (0.278 ± 0.015, 0.229 ± 0.088, respectively) , cutaneous tuberculosis group (0.171 ± 0.010, 0.103 ± 0.016, respectively) and erythema induratum group (0.200 ± 0.015, 0.118 ± 0.021, respectively) than in the normal control group (both 0, all P < 0.05) . Immunofluorescence staining showed co-expression of SLC35E1 and SLC35E2B with CD68 in skin lesions of the patients with leprosy, nontuberculous mycobacterial infection, cutaneous tuberculosis. Conclusion:Both SLC35E1 and SLCE2B were markedly highly expressed in skin lesions of patients with Mycobacterium infections.
