? AIM: To investigate the efficacy and safety of phacoemulsification combined with intraocular lens implantation in the treatment of shallow anterior chamber with cataract.?METHODS: Retrospective case series. From February 2014 to July 2015 in our hospital,65 eyes in 65 patients with cataract were enrolled and divided into mild and high risk of shallow anterior chamber group. Best-corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) , central anterior chamber dept ( CACD ) , angle opening distance ( AOD ) , complications pre- and post treatment, were observed and analyzed as outcome measures.?RESULTS: In this study, the mild shallow anterior chamber group included 34 eyes; postoperative BCVA were improved in 29 eyes, with 4 eyes remaining stable and decreased in 1 eye; BCVA was improved in 16 eyes, with 10 eyes remaining stable and decreased in 5 eyes in high risk of shallow anterior chamber group postoperatively. BCVA had a better prognosis in the mild shallow anterior chamber group than another group ( t=-2. 956, P<0. 05). Meanwhile, IOP decreased by 5. 71± 2. 07mmHg and CACD increased by 1. 37 ± 0. 38mm in the mild shallow anterior chamber group, by 9. 77±4. 04mmHg and 1. 67±0. 43mm respectively in high risk group, and the difference has statistical significance ( t=-5. 02,-3. 04; P<0. 05). The mean preoperative nasal AOD500 was 200. 57± 33. 74μm, and they were 346. 62 ± 101. 37μm and 410. 75 ± 137. 48μm and 398. 69 ± 122. 28μm respectively at postoperative 1d, 1 and 3mo, and all nAOD500 comparing with preoperative were increased obviously, and the difference has statistical significance (F=203. 75, P<0. 01). And AOD500 at temporal, superior and inferior presented similar trends. Complications were corneal edema ( 5 eyes ) , transient intraocular hypertension ( 2 eyes ) , posterior capsular opacification ( 4 eyes ) , and posterior capsular rupture (1 eye).?CONCLUSION:Micro incision cataract surgery is useful, effective and safe in patients with cataract and shallow anterior chamber which can stabilize or improve BCVA, reduce IOP, deepen CACD and open the anterior chamber angle.

Objeetive To investigate the expression of claudin-4 in the eutopic and ectopic endometfium of women with endometriosis and evaluate the role of clandin-4 in the pathogenesis of endometriosis.Methods Thiny-five women with endometriosis and 35 controls were studied.Expression of elaudin-4 was investigated using immunohistochemistry,western blot and RT.PCR,respectively.Morphologic change of tight junction was also observed in different kinds of endometria.Results (1)G1andular epithelial cells of control endometrium and eutopic endometrium showed intact tight iunctions in electron micrographs,whereas the morphology of tight junctions in ovarian endometriotic tissue was disrupted and collagen bundles could be easily detected.(2)The immunohistochemical staining of claudin-4 was localized to the glandular epithelial cell membrane.Deftcient or weak staining Wag found in ovarian endometriotic tissues. In control endometrium.eutopic and ectopic endometrium of women with endometriosis,the expression of clandin-4 protein Was 89±24.84±22 and 27±14.respectively.Relative expression of claudin-4 mRNA Was 14.5±6.8,13.8±9.5 and 2.6±2.5.respectively.Expression of claudin-4 Was significantly lower in the ectopic endometriotic tissue than in the eutopic cndometrium and the control at both mRNA and protein levels(P<0.05). N0 significant difference Was foand between eutopic endometrium from women with endometriosis and control endometrium from women without endometriosis (P>0.05).Conclusion Down-regulated expression of claudin-4 might play a pathogenic role in the formation of endometriosis.

[ ABSTRACT ] AIM: To investigate the toxicity and reproductive effect of vascular endothelial growth factor ( VEGF)/basic fibroblast growth factor ( bFGF) complex peptide vaccine ( VBP3) on the female-mice.METHODS:The VBP3 was purified with Ni-NTA affinity chromatography.The female BALB/c mice were immunized with the purified VBP3.The antibody titer in the serum was detected by ELISA.The data of the body weight and the organ weight of the par-ent mice were gathered and analyzed, and the pathological changes of the organs were observed with HE staining to investi-gate the toxicity of VBP3.To investigate the toxicity of VBP3 in the F1 mice, the parent immunized female mice were ma-ted with the parent non-immunized male mice.After the F1 mice were born, the survival rate was calculated, the change of the body weight and the organ weight of the F1 mice were also determined.The pathological changes of the organs in F1 mice were also observed with HE staining.RESULTS: In the parent mice, high titers of the antibodies were detected against VEGF and bFGF, and no difference of the body weight, the organ weight and the pathological change between the immunized mice and control mice was found.In the F1 mice, a low titer of anti-bFGF antibody was detected compared with blank group.The survival rate in control group was higher than that in immunized group.In the 2 groups of the F1 mice, no obvious difference of the weight of the spleen, kidney, lung and heart was observed, and there was some difference in the weight of liver between the 2 groups.The results of the HE staining in the F1 mice showed some difference in the liver between the 2 groups.CONCLUSION:VEGF/bFGF complex peptide vaccine has no obvious organ toxicity in the parent female mice, but has some side effects on the reproductive and the healthy processes of F1 mice.

Objective To describe a technique of closed reduction and percutaneous internal fixation for the treatment of displaced patellar fractures and evaluate the clinical results. Methods Fifteen cases (nine males and six females with mean age of 35.5 years, ranging from 24 to 65 years) with displaced patellar fractures were treated with closed reduction (or an arthroscopic-assisted reduction) and percutaneous cannulated screw fixation (or Kirschner wire tension band wiring technique) under guidance of fluoroscopy or C-arm X-ray tomography. Controlled passive range of motion exercises started on the first postoperative day. The mean follow-up was 28 months (24-35 months). Results All cases healed successfully with healing time of (1.2?2.2) months and mean Lysholm II score of 86.8 (79-96), except for one patient regained full knee range of motion. Compared with the contralateral side, a mean quadriceps atrophy of 0.8 cm was seen in unilateral cases based on Tandogan measurement. There was no implant failure or postoperative infection. Conclusions The technique of closed reduction and percutaneous internal fixation is appropriate for displaced, transverse, longitudinal or oblique patellar fractures and can facilitate early postoperative range of motion exercises and accelerate rehabilitation of the affected knee with few complications and minor incision without disturbing blood supply of the patella. But, this method is not suitable for severely comminuted fractures.

AIM:To investigate the expressions of methylthioadenosine phosphorylase(MTAP)and ornithine decarboxylase(ODC)in human ovarian cancer.METHODS:60 fresh samples of ovarian cancer were collected.The expressions of MTAP mRNA and protein were analyzed by using RT-PCR and Western blotting,respectively.ODC activity was measured by high performance liquid chromatography.RESULTS:The expression levels of MTAP mRNA and protein in ovarian cancer were lower than those of control.In 9 of the 60 samples(15%)there were absence of detectable MTAP mRNA and protein.No significant relevance was found between the expression of MTAP and clinical pathologic features.ODC activity in ovarian cancer was(3.82?1.03)U,which was higher than that of normal ovarian tissues(1.38?0.59)U.ODC activity was related with tumor grade.In MTAP-deficiency ovarian cancer tissues ODC activity was significantly increased when compared with that of MTAP-expressing ovarian cancer samples.CONCLUSION:Down-regulated MTAP expression and up-regulated ODC activity really exist in ovarian cancer.Activation of ODC resulting from MTAP deletion may be one of the pathogenetic factors of ovarian cancer.

OBJECTIVETo evaluate the application of bone turnover markers bone alkaline phosphatase (BALP) and N-MID osteocalcin (N-MID) in monitoring of osteoporosis treatment with recombined parathyroid hormone 1-34 (rhPTH1-34).

METHODSThe bone mineral density (BMD) of the lumbar spine L2-L4 and the proximal femur were examined by dual energy X-ray absorptiometry (DXA) before and 6 and 12 months after rhPTH 1-34 treatment. Meanwhile, serum levels of BALP and N-MID were detected by electro-chemiluminescence assay.

RESULTSSix months after rhPTH 1-34 treatment, the BMD of proximal femur remained unchanged, and the BMD of the lumbar L2-L4 spine increased from 0.753 g/cm(2) to 0.781 g/cm(2) (P<0.05); while serum levels of N-MID increased from 15.46 ng/ml to 27.07 ng/ml(P<0.01), BALP from 14.05 μg/ml to 24.31 μg/ml(P<0.01). Twelve months after drug administration, no significant changes were observed in BMD of proximal femur, and the BMD of the lumbar spine L2-L4 increased from 0.753 g/cm(2) to 0.807 g/cm(2)(P<0.01) while serum levels of N-MID and BALP increased from 15.46 ng/ml and 14.05μg/ml to 49.38 ng/ml and 33.99 μg/ml, respectively (both P<0.01).

CONCLUSIONSerum levels of BALP and N-MID are more sensitive than BMD. Combination of two methods may provide better indicators for monitoring of osteoporosis treatment.

Objective To explore the clinical manifestations,imaging findings,pathological classification and treatment of congenital cystic adenomatoid malformation (CCAM)of the lung.Methods The clinical features,imaging findings,pathology information,diagnosis,treatment method and its prognosis of children with CCAMconfirmed by ope-ration and pathology were retrospectively analyzed in Yuying Children′s Hospital Affiliated to Wenzhou Medical Univer-sity from August 2006 to August 201 4.Results Eleven patients were boys and 4 patients were girls.One case had a-symptomatic clinical features,1 2 cases had pulmonary infection,1 case had recurrent chest pain,and 1 case had de-pressed deformity in sternum inferior segment.Chest CT scanning indicated that 9 cases had multiple gas cysts at unila-teral side of lung,among which 1 case was of funnel chest and pulmonary sequestration,1 case of huge cyst containing air and fluid at inferior lobe of left lung,and 4 cases of high density lung shadow;CT examination indicated that 1 case had recurrent chest pain and eventration of diaphragm of the right side combined with pulmonary sequestration.All ca-ses were treated by surgical resection,of whom 1 case was given cystectomy and sequestrectomy,diaphragmatic plication respectively,1 case complicated with funnel chest disease underwent lesion pulmonary lobectomy,sequestrectomy and minimally invasive corrective surgery in pectus excavatum (Nuss surgery),and the remaining 1 2 cases received lesion pulmonary lobectomy.All of 1 5 cases recovered well without complications.Pathological classification type of CCAMin-cluded 1 1 cases of type Ⅰ,3 cases of type Ⅱ and 1 case of type Ⅲ,among which 2 cases had pulmonary sequestration. Conclusions CCAMis a rare disease which can be discovered along with pulmonary infection.Multiple gas cysts are the most common imaging findings and the preoperative diagnosis of CCAM is mostly based on chest CT examination. Type Ⅰ and type Ⅱ are the most common pathological classification.The surgical resection should be given early surgi-cal resection and the prognosis is usually good.

Objective To investigate the changes in ATPase activity of diaphragm in rats with acute organophosphorus poisoning (AOPP) and to explore the effect of Xuebijing injection on the ATPase activity. Methods 24 clean healthy Spraue-Dawley(SD)rats were divided into control group,model group and Xuebijing treatment group by means of random number table,with 8 rats in each group. AOPP model was established by intra-gastrical administration of 50 mg/kg oxide dimethoate. In Xuebijing treatment group,after oxide dimethoate administration,intraperitoneal injection of Xuebijing(10 mL/kg)was given at the same time,while in control group and model group,equal amount of normal saline(NS)was injected via the same route. The rats were sacrificed at 6 hours after model formation,and their diaphragms were taken sterilely. The activities of Na+-K+-ATPase and Ca2+-ATPsae of diaphragms were detected by enzyme linked immunosorbent assay(ELISA). The histopathological changes in diaphragms of rats were observed with light microscopy. Results 6 hours after intoxication,the diaphragm Na+-K+-ATPase activity of rats in model group was markedly lower than that in control group(mmol?h-1?g-1:5.22±0.74 vs. 9.98±0.37,P<0.01),while the Na+-K+-ATPase activity in Xuebijing treatment group(6.93±1.14) was markedly higher than that in model group(P<0.05). The diaphragm Ca2+-ATPase activity of rats in model group was markedly lower than that in control group(mmol?h-1?g-1:7.45±0.74 vs. 12.08±0.74,P<0.01),while the Ca2+-ATPase activity in Xuebijing treatment group(9.35±1.67)was obviously higher than that in model group(P<0.05)after intoxication for 6 hours. Light microscope observation indicated that there were swelling and necrosis in diaphragm in model group,while in Xuebijing treatment group no necrosis was found. Conclusion The diaphragm was degenerated and necrotic in AOPP rats,Xuebijing injection can lessen the injury in such rats,and the curative effect may be related to the improvement of the Na+-K+-ATPase and Ca2+-ATPsae activities of diaphragm.
