Objective:To investigate the morphology character of sagittally unstable intertrochanteric fractures and reduction methods.Methods: A retrospective study was used to analyze the clinical data of sagittally unstable intertrochanteric fractures cases,which were treated with proximal femoral nail anti-rotation (PFNA) fixation from March 2009 to June 2016.In the study,36 cases were followed up completely,in which 17 cases accepted open reduction,and the other 19 cases accepted minimally invasive reduction.The operation time,amount of bleeding,the fluoroscopy times,postoperative radiographic measurements,such as tip-apex distance (TAD) and sliding distance of the spiral screw,and hip Harris scores were analyzed.The morphology character of the fractures was documented and investigated.Results: The average follow-up time was 15 months.The amount of bleeding of the open reduction group was (170.5±19.7) mL,and the amount of bleeding of the minimally invasive group was (54.7±12.5) mL.The amount of bleeding of the minimally invasive group was significantly less than that of the open reduction group (P<0.001).Between the two groups,there were no significant differences in other evaluation parameter,including operation time (P=0.054),the fluoroscopy times (P=0.053),fracture healing time (P=0.305),postoperative radiographic measurements,such as TAD (P=0.317) and sliding distance of the spiral screw (P=0.206),and hip Harris scores (P=0.459).In regard to morphology character of the fractures,the proximal anterior unstable fractures with separation displacement were more common than the proximal posterior unstable fractures with impaction.The characteristic feature of the proximal anterior unstable fractures was the proximal anterior and medial long oblique fracture,and a V shape cortical defect in the distal fracture fragment on the externally rotation X-ray.Conclusion: Sagittally unstable intertrochanteric fractures can be divided into the proximal anterior unstable fractures with separation displacement,and the proximal posterior unstable fractures with impaction.The two types have their own morphology character individually.The reduction should be performed by minimally invasive techniques.

Background Lensectomy with anterior capsule preserving is still advisable under specific conditions during vitrectomy.Although lens epithelial cells were polished off during surgery,opacification in varying degrees could be observed.Understanding the composition of proliferative anterior capsule membrane is of an important clinical significance for the prevention and manegement.Objective This study was to investigate the management and pathology of the pupillary area membranous opacity underling preserved anterior capsule after lensectomy in diabetic eyes with silicone oil tamponade.Methods Twenty-three eyes of 21 patients with proliferative diabetic retinopathy (PDR) and cataract received vitrectomy combined with lensectomy preserved anterior capsule in China-Japan Friendship Hospital from January to December 2013,and the proliferative anterior capsular membrane specimens with the opacification grade C or D were obtained.The fibrotic membrane underlying anterior capsules were removed in order to make a clear optical area during the operation of silicone oil removal.The proliferative membrane at pupillary area was cut off by cutter probe for the eyes with the membrane attaching tightly or partial capsule laceration occurred.The available specimens were examined under the optical microscope and polarized microscope respectively after hemotoxylin and eosin staining,Van Gieson collagen staining,Masson collagen staining and Picrosirius staining.Results The proliferative fibrosis membranes were pilled to get a clear pupillary area in 15 eyes,with the successfully rate 65.2％ (15/23).In 14 eyes with degree C opacity,the proliferative fibrosis membranes were pilled in 9 eyes,with the successfully rate 64.3 ％ (9/14),and 5 eyes received anterior capsule cutthrough by cutter in pupillary area,with a diameter of 3-4 mm,and available specimens were obtained in 3 eyes.In 9 eyes with degree D opacity,the proliferative membranes were pilled in 6 eyes,with the successfully rate of 66.7％ (6/9),and 3 eyes underwent cut-through by cutter,and available specimens were obtained in 7 eyes.The best corrected visual acuity was obviously improved in 20 eyes and unchanged in 3 eyes after surgery.The histopathological examination showed fibroblasts,pigment particles and intracellular and extracellular vacuolus formation by hemotoxylin and eosin staining,fibril tissue with the pinke staining by Van Gieson,collage formation with green color by Masson staining in the specimens.Picrosirius staining plus polarization microscopy observation revealed that the collagen consisted of abundant type Ⅰ collagen with stronger reddish yellow color and small amount of type Ⅲ collagen with green color.Conclusions A combination of silicon oil removal with proliferative mambrane pelling is a available way to restore pupillary transparency in the eyes of PDR with cataract and silicone oil tamponade eyes.Proliferative residual lens epithelial cells,pigment epithelial cells and silicon oil granules are the main composition of opacity mambrane.The type Ⅰ collagen is dominant in proliferative collagen tissue.

Objective Prostate cancer is one of the most common cancer in males .The article was to investigate the expres-sion and clinicopathological significance of VEGF-C mRNA in prostate cancer , finding the molecular marker for early diagnosis and prognosis assessment of prostate cancer . Methods TaqMan real-time polymerase chain reaction ( PCR) analysis was used to detect the expression of VEGF-C mRNA in 3 prostate cancer cell lines(PC-3, DU145 and LNCap), 32 cases of prostate cancer (Pca) sam-ples and 15 cases of benign prostatic hyperplasia (BPH).Analysis was also made on the correlations of VEGF-C mRNA expression, clinicopathological features and prognosis . Results High levels of VEGF-C mRNA were detected in PC-3 ( 153 .31 ±26 .24 ) and DU145(194.62 ±41.36)compared to LNcap(1.00 ±0.00).The expression of VEGF-C mRNA in prostate cancer tissues was 3.43 folds higher than that in the benign prostatic hyperplasia tissues ([13.67 ±1.95] vs [11.89 ±1.63], P=0.004).The high expres-sion of VEGF-C mRNA in prostate cancer was associated with high Gleason score ( P =0.004 ) and lymph node metastasis ( P =0.015).In patients with high expression and low expression of VEGF-C mRNA, the 3-year survival rate was 12.5%and 40.0%re-spectively(P=0.033). Conclusion The VEGF-C mRNA expression may be related to the biological behavior of prostate cancer .It is suggested that VEGF-C mRNA can be used as a prognostic marker for prostate cancer .

Objective To explore the short and long term curative effects of percutaneous transhepatic cholangioscopic lithotomy (PTCSL) in the treatment of intrahepatic stone (IHS).Methods 38 IHS patients were enrolled,who were treated with PTCSL between January 2008 and July 2013.Results PTCSL was successfully completed in all the 38 IHS cases.Stone clearance rate was 84.2％ and the average episode of stone removal was (2.6 ± 0.9) times.Average diameter of percutaneous transhepatic fistula was (18.4 ± 0.6) F and the average time from percutaneous transhepatic puncture and fistulization to cholangioscopic lithotomy was (7.2 ± 0.7)d.The average operation time was (68 ± 20) min,intraoperative blood loss was (20 ± 13) ml,and hospitalization was (4 ± 2) days.The hepatolith recurrence rate in patients with stones completely removed was 37.5％ (12/32),and 1 case developed into biliary cirrhosis.Patients with calculi residual suffered from higher hepatolith recurrence rate of 83.8％ (5/6),with biliary cirrhosis found in 1 case.Conclusions PTCSL is safe and effective in treating primary IHS,which is indicated in multiple recurrent IHS especially in after biliary surgery patients.It has the advantages of minimally invasion,less bleeding,less postoperative pain,less complications,and fast postoperative recovery.

Lactic acid bacteria (LAB) are traditional dairy strains which have a long history of safe use. They are a kind of food-grade microorganisms that can be used in industry to produce lots of food and drink, such as yoghourt. In the last two decades the physiology and genetics of these bacteria have been thoroughly studied. Because of their genetic accessibility and easy to handle, LAB, in addition to their traditional applications, have been extensively developed and used for the expression of heterologous genes. So they have an important foreground in agricultural, medical and many other fields. People have developed a series of food-grade gene expression systems of LAB. LAB, especially their model strain Lactococcus lactis and their most useful food-grade induced expression system--nisin controlled gene expression system NICE and its food-grade inducer nisin, food-grade host, expressing vectors and applications in expressing heterologous proteins of NICE will be introduced.
