The role of autophagy is known to be highly complex and context-dependent, and may be characterized as both tumor suppression and tumor promotion in some tumors, such as breast cancer and prostate cancer. This review outlines recent advances in the studies of the involvement of autophagy in the development, progression and treatment of prostate cancer, focusing on autophagy modulation during androgen deprivation, with a special discussion on the regulatory effect of androgens on the autophagy of prostate cancer cells. A critical evaluation and analysis of the studies suggests that autophagy inhibition combined with androgen deprivation therapy is a promising approach to the treatment of prostate cancer.

OBJECTIVETo explore the improvement of the method for the treatment of supracondylar fractures of humerus in order to prevent and decrease the occurrence of cubitus varus.

METHODSOne hundred and ninety-seven patients with supracondylar fractures of humerus included 167 males and 30 females with an average age of 8.7 years old ranging from 3 to 12 years. There were 179 cases of extention and 18 cases of flexion. Six cases were open fractures. Thirty-four patients of fractures underwent fixation by only plaster slab, 53 underwent manipulative reduction and fixation by plaster slab, 23 underwent traction reduction and fixation by plaster slab, 87 underwent surgical operation. Among the cases of operation, 29 cases adopted anterior-lateral incision of elbow and 85 adopted posterior-interior incision of elbow.

RESULTSAmong the 197 cases, 191 cases were followed up for 1 to 5 years with an average of 3.7 years. According to the correlated curative effect evaluation of supracondylar fractures of humerus, the results were excellent in 142 cases, good in 27, fair in 13, poor in 9. Cubitus varus occurred in 8 cases.

CONCLUSIONThe objective factors for the occurrence of elbow varus do exist. However, during the treatment of these fracture, if strict correction of the ulnar deviation and stability are maintained during the reduction, the rate of occurrence of elbow varus could made to decreased a minimum.

To comparatively evaluate the efficacy and post-operative complications of the Madigan's prostatectomy (MPC) and suprapubic prostatectomy (SPPC). Methods: A total of 43 patients with benign prostatic hyperplasia were divided into two groups: 21 underwent MPC and 22, SPPC. In all the patients, the international prostate symptom score (IPSS) and urinary pressure-flow studies were assessed before and 6 months after operation. The International Continence Society (ICS) nomogram, Abrams-Griffiths (AG) number and linear passive urethral resistance relation analysis (L-PURR) were used to diagnose and grade bladder outlet obstruction (BOO). The IPSS and the urodynamic parameters before and after operation, as well as the advantages and post-operative complications were recorded and compared. Results: Patients of both the MPC and SPPC groups had a significant improvement in IPSS and urodynamic parameters. Obstruction was relieved in 81.0% of MPC and 86.4 % of SPPC patients. MPC has the advantages of the absence of postoperative hematuria and post-catheter stricture, a shorter period of hospitalization, and lower incidence of retrograde ejaculation and erectile dysfunction. Conclusion: Both MPC and SPPC can effectively relieve BOO. MPC has certain advantages and a lower incidence of complications as compared with SPPC.

In adipose tissues from sreater omentum of patients with type 2 diabetes,the mRNA and protein expressions of human rearranged immunoglobulin?light chain (HSIGVL) 022 were measured by the fluorescent quantitative RT-PCR and immunohistochemistry respectively.The results showed that mRNA and protein levels of HSIGVL022 were up-regulated in patients with type 2 diabetes.The mRNA level of HSIGVL022 was linearly correlated with insulin resistance index,suggesting that this gene may play a role in the pathogenesis of insulin resistance and type 2 diabetes.

Objective To investigate the therapeutic method of metabolic acidosis in long-term sur- vival patients undergoing simultaneous pancreas and kidney transplantation.Methods A 45-year-old fe- male patient,who had undergone simultaneous pancreas and kidney transplantation(due to diabetic ne- phropathy and uremia)with bladder drainage 2 years before,developed severe metabolic acidosis,and thus underwent surgical conversion from bladder to ileal drainage.The procedure was as follows.The stoma of duo- denocystostomy was isolated and resected.The site of cystostomy was closed in two layers.The graft duode- num was then anastomosed to a loop of the recipient's ileum,which was proximal 40 cm from the ileocecum in a side-to-side manner.Results The metabolic acidosis resolved postoperatively.The patient received conventional immunosuppressants.The hospital stay was 30d.Follow-up of 4 years showed normal pancreas and kidney functions.Conclusions Conversion from bladder to ileal drainage is safe and effective for metabolic acidosis related to the exocrine secretions of bladder drained pancreas graft in simultaneous pancre- as and kidney transplant recipients.

Aim The therapeutic effect of "shen-bing NQ 5", a preparation of traditional Chi-nese medicine on adenine-induced chronic nephritis in rats was studied. MethodsChronic nephritis in rats was induced by giving adenine 80 mg?kg-1?d-1 orally. Themodel rats were treated by "shen-bing No 5" in different dosages. Levels of urea ni-trogen(BUN), creatinine (Cr), total protein(TP), and Na+ in serum and or urine weredetected and the changes of kidney were obseraed. Results The "shen-bing No 5"markedly lowered the levels of urine protein in 24 hours, BUN in urine and BUN, Na+in serum (P

· ATM:To analyze bacterial spectrum and drug sensitivity in conjunctival sac of cataract patients of Kazak.
· METHODS:A total of 538 cases of conjunctival sac secretion in cataract patients of Kazak were collected.The samples were cultured and their sensibilities to antibiotics were tested.
· RESULTS: The bacterial culture was positive in 214 cases.The positive rate was 39.8%. The variety of pathogenic bacteria were mainly made up of gram positive cocci ( 88.3%), and most of them were Staphylococcus epidermidis ( 66.4%), followed by Micrococcus(9.8%).Sex had no effect on conjunctival bacteria rate in the cataract patients of Kazak, while age, place of residence had an effect on camier rate. The camier rate of conjunctival bacteria was significantly higher in people over 60 years old than that in people with age between 40 to 59 years old.And the people from city had a significant lower bacteria positive rate than those from countryside and pastoral. Most of grams were sensitive to Vancomycin, Teicoplanin, Rifampicin, Duly cloth mildew mutual and Amikacin, the tolerance was less than 20%, and they usually had higher tolerance to Penicillin, Erythromycin, Tetracycline and Chloramphenicol (>70%) .
·CONCLUSlON:Gram positivecocci is the most common bacteria in conjunctival sac in cataract patients of Kazak. Staphylococcus epidermidis was most common, followed by Micrococcus.The germ-carrying rate of conjunctival SAC in Kazakh population is associated with the patient’s age and area of residence.The clinical use of antibacterial drugs should be strictly grasp the indications, to reduce the incidence of bacterial resistance.

OBJECTIVETo develop an effective and feasible method to construct three-dimensional finite element model of the whole edentulous maxilla and cranial skeleton.

METHODSBased on three-dimensional computer aided design model which was constructed by multi-slices helical CT scanning data of a male's head in specialized software, three-dimensional finite element model of edentulous maxillary and cranial skeleton was established; the stresses distribution in maxilla was investigated under occlusal load with computer simulated a complete overdenture.

RESULTSThe three-dimensional finite element model of edentulous maxilla and cranial skeleton had favorite similarity in geometry, the distributions of stresses in maxilla and the wall of maxillary sinus could be clearly observed.

CONCLUSIONSThe study verifies that this three-dimensional finite element modeling method is feasible and effective.
