Background Researches showed that the incidence rate of cataract is high in the nickel mining area. Nickel sulphate can apparently inhibit the metabolism and proliferation of human lens epithelium cells. But the study on the injury mechanism of nickel on lens is still seldom. Objective Present study was to investigate the effect of nickel sulphate on the lens of SD rats. Methods Forty-five SPF SD rats aged from 7 to 14 days were grouped randomly into subcutaneous injection group, intraperitoneal injection group and blank group. Nickel sulphate of 2 g/L ( 10 mg/kg) was subcutaneously or intraperitonealy injected for 45 days. The opacity of rat lens was examined under the slit lamp at two-week interval and scored based on the criteria of LOCS II and LOCS III. The rats were sacrificed in 45 days after experiment and the lens were obtained for the pathological examination. Result The mean score of the anterior subcapsule opacity of rat lens was obviously higher in subcutaneous injection group compared with blank control group with a significant difference between them (t= 14. 311, P < 0. 05 ) , but no significant difference in the anterior subcapsule opacity between intraperitoneal injection group and blank control group (t = 4. 355 , P>0. 05 ). The score of posterior subcapsule opacity of lens were evidently higher in both subcutaneous injection group and intraperitoneal injection group than the blank control group (t = 9. 316,P = 0. 004;t = 7. 464, P = 0. 009) ,so was the mean score of the anterior +posterior subcapsule opacities(t = 23. 387,P=0. 000;t= 10. 533,P = 0. 002) and the total score of rat lens opacity ( t = 12. 358 , P = 0. 001; t = 10. 188 , P = 0. 003 ) . No significant differences were found in cortex opacity score and nuclear opacity score among three groups ( P > 0.05 ). Histopathology examination revealed that the degeneration of lens collagen protein was more serious in subcutaneous injection group and intraperitoneal injection group than the blank control group,and the injury degree of lens collagen protein was more dominant in subcutaneous injection group. Conclusion System administration of nickel sulphate induced the injury of anterior and posterior subcapsule of lens in SD rat.

BACKGROUND:The majority of studies focus on the lesions of spinal cord injury, while little evidence is available on the change of morphology and structure of distal nerve, muscle and motor endplates fol owing spinal cord injury.
OBJECTIVE:To investigate the time window change of the morphology of motor neurons and skeletal muscles caudal to the lesion after spinal cord injury in rats.
METHODS:Fifty healthy adult Sprague-Dawley rats were randomly divided into three groups:control group (n=5;without treatment), sham operation group (n=10), and spinal cord injury group (n=35). The sham operated rats only received laminectomy. In the spinal cord injury group, rats were subject to complete T 10 spinal cord injury by total laminectomy and cord transverse resection. Then the morphological change including sciatic nerve, motor endplate and median gastrocnemius was observed for each group at 1, 2, 4, 12, 24 weeks after injury.
RESULTS AND CONCLUSION:(1) The myelin sheath layers of sciatic nerve were separated partial y at 4 weeks in rats with spinal cord injury, the myelin sheaths were fragmented with the regeneration of thin-myelinated and unmyelinated axons at 12 weeks. There was a decrease in myelinated axons and an increase in thin-myelinated and unmyelinated axons at 24 weeks. (2) The synaptic gutters of motor endplate, the presynaptic and postsynaptic membrane and synaptic space were distinct at 4 weeks in rats with spinal cord injury, the degenerated motor endplates coexsisted with the intact ones at 12 weeks. The motor endplate disappeared at 24 weeks. (3) There was a slight decrease in muscle cross-sectional area at 2 weeks in rats with spinal cord injury, but no structural change was found, the membrane of myocytes was partial y weakened at 4 weeks, the border of myocytes was obscure with hyperplasia of connective tissue at 12 weeks, and myocytes gathered and in fusion at 24 weeks. As natural history of completely transected spinal cord injury in rats, there were significant changes in morphology of peripheral nerve, motor endplate and skeletal muscles caudal to the lesion at 12 weeks, and the changes were destructive at 24 weeks.

Objective To explore the clinical treatment of procedure for prolapse and hemorrhoids (PPH) combined with transrectal Block for rectocele (Block procedure).Methods Eighty-six hospitalized patients with rectocele were divided into two groups according the odevity of month:A group (odd month,PPH combined with Block procedure group,49 cases) and B group [even month,stapled trans-anal rectal resection (STARR),37 cases].The treatment conditions were compared between two groups.Results There were no statistical differences in degree of postoperative pain,healing rate between two groups (P ＞ 0.05).The operating time,postoperative hemorrhage rate,cost of hospitalization,patient satisfaction score and rectocele depth after 1 year in A group were significantly better than those in B group [(25.5 ± 2.8) min vs.(36.8 ± 4.6) rmin,2.0％(1/49) vs.13.5％(5/37),(7 359 ± 580) yuan vs.(10 928 ± 610) yuan,(9.1 ± 0.8) scores vs.(8.2 ± 0.7) scores,(5.02 ± 0.71) mm vs.(9.73 ± 1.31) mm],there were statistical differences (P ＜ 0.05).Conclusions PPH combined with Block procedure for rectocele had a significant clinical effect,it is a safe new method with small surgical trauma,a better choice to prevent the recurrence of rectocele,reduces the patients economic pressure obviously.So it is worth to clinical promotion.

Objective To investigate the effect of recipient's pre-transplant triglyceride (TG) abnormalities on early graft function (EGF) after kidney transplantation.Methods According to the inclusion and exclusion criteria,154 identified living-kidney transplant recipients in the 309 Hospital of Chinese PLA from Jan.2011 to Dec.2014 were enrolled in present study,including 124 males and 30 females,and aged of 31.9 ± 8.4 years.The cohort was divided into two groups:TG normal group (0.40＜TG≤1.70mmol/L,n=107) and TG abnormalities group (TG＞l.70mmol/L or require lipid lowering therapy,n=47).The incidences of poor early graft renal function (PEGF),slow graft function (SGF) and delayed graft function (DGF) were compared between the two groups,and then the serum creatinine (Scr) levels were compared among the patients showing immediate graft function (IGF) at 3rd,7th and 30th day after transplantation.The ROC curve was drawn up taking TG as diagnosis index to explore the optimal cut-offvalue for predicting PEGF,SGF and DGF after transplantation.Results Compared with the TG normal group,the TG abnormalities group showed significantly higher incidence of PEGF and DGF (P＜0.05).Among the IGF patients,the TG abnormalities group showed higher Scr level at the 7th and 30th day after transplantation (P＜0.05).The area under ROC curve (AUC) reflected TG levels for PEGF,SGF and DGF were 0.774,0.704 and 0.818,respectively (P＜0.05).The optimal cut-offvalues were all 1.37mmol/L.Conclusions Recipients with abnormal pre-transplant TG level may have worse EGF after renal transplantation.The risk of developing PEGF,S GF and D GF tends to emerge when pre-transplant TG level is higher than 1.37mmol/L.

Objective To investigate whether the donor's glomerular filtration rate (GFR) to recipient's weight ratio (Dg/Rw) is a useful tool to predict early clinical outcome in living-related do-nor transplantation.Methods A total number of 108 living donor transplant recipients in the Chinese Military 309th Hospital from Jan.2014 to July 2015 were enrolled in this study.The patients who had multi-organ transplantation or developed grafts rejection,delayed graft function,hydronephrosis or renal vascular stenosis were excluded.The 90 qualified recipients were divided into G1 group (Dg/Rw ≤0.81),G2 group (Dg/Rw 0.81～1.11),and G3 group (Dg/Rw≥1.12).We respectively analyzed the relationship between recipient's serum creatinine Scr and Dg/Rw at 3-,7-,30-day and 1 year after transplantation.Results Scr at 3-,7-,30-day and 1 year after transplantation had linear correlation with Dg/Rw.As compared with G1 and G2 groups,Scr level was significantly reduced in G3 group at different time points (P＜0.05).Conclusion Dg/Rw has a negative relationship with Scr level after renal transplantation.Pre-transplant Dg/Rw is a potential index to predict the early clinical outcome in living-related donor transplantation.

Objective To investigate the correlation between de nove anti-endothelial cell antibodies (AECA) and adverse events after renal transplantation and the effect of transplanted renal function within six months after operation.Methods The expression of AECA in serum of 85 renal transplant recipients was detected by indirect immunofluorescence assay (ⅡF) before and 1 day,3 days,7 days,15 days and 1 month after renal transplantation.The patients were divided into double positive group (AECA positive before and after surgery),single positive group (postoperative de nove AECA positive) and negative group (preoperative and postoperative AECA negative) according to AECA test results.The occurrence of adverse events in each group such as DGF,rejection,infection and so on,as well as the serum creatinine levels were recorded at each time point within six months.Results Of the 85 recipients,29 were positive for AECA,including 19 in the double positive group,10 in the single positive group,and 56 in the negative group.The incidence of rejection in single positive group (30％) was higher than that in the rest two groups (5.3％ for double positive group,and 17.9％ for negative group),but there was no statistically significant difference (P =0.21).The incidence of DGF in the single positive group,double positive group and negative group was 70.0％,26.3 ％ and 32.1 ％ respectively.The positive rate of the single positive group was significantly higher than that of the rest two groups (P =0.04),and the duration of DGF was significantly longer in the single positive group than that of the rest two groups (P＜0.01).The incidence of infection in the single positive group,double positive group and negative group was 20.0％,21.1％ and 8.9％respectively,and there was no significant difference among the three groups (P =0.31).As compared with the double positive group and the negative group,the serum creatinine level was significantly increased in the single positive group at 1st week,1st month,3rd month and 6th month after operation (P =0.02,P =0.04,P =0.04 and P =0.02 respectively).Conclusion Postoperative AECA can increase the risk of DGF,prolong the duration of DGF,and affect the recovery of renal function within 6 months after renal transplantation.

Objective To study the therapeutic effect of improved STARR (Sehapayak as a control)in the treatment of moderate and severe rectocele.Methods 70 patients diagnosed with rectocele from Jan.2015 to Oct. 2015 were selected and randomly divided into 2 groups,35 cases in each group.They were treated with either improved STARR or Sehapayak surgery.The operation time,intraoperative blood loss,postoperative pain scores, patients'satisfaction and hospitalization days were compared between 2 groups.The ODS scores and therapeutic effects were compared in 1st week,1st month,3rd month and 6th month after treatment.The defecography was implemented and compared between 2 groups before treatment and 1st week and 6th month after treatment.Results The operation time,intraoperative blood loss,postoperative pain scores,hospitalization days and time to return to work were signifi-cantly lower in STARR group than those in Sehapayak group[(29.76 ±8.40)min vs (48.38 ±9.04)min;(14.43 ± 8.16)mL vs (77.80 ±20.58)mL;(4.29 ±1.76)points vs (6.71 ±2.04)points;(6.71 ±1.22)d vs (11.23 ± 3.64)d;(7.20 ±1.36)d vs (13.14 ±2.60)d;t =8.934,16.935,5.338,6.955,11.959,all P <0.05],and the patients'satisfaction was significantly higher in STARR group[(8.83 ±0.98)points vs (7.54 ±1.20)points,t =4.908,P <0.05].There were no significant differences in efficacy between 2 groups at any time point (P >0.05). The ODS score was (20.97 ±4.38)points before treatment,(4.71 ±1.30)points 1week after treatment,(2.94 ± 0.91)points 1month later,(1.68 ±1.04)points 3months later and (0.97 ±0.88)points 6mons later in the observa-tion group.The ODS scores in the control group were (19.88 ±4.09)points,(4.65 ±1.28)points,(3.51 ±1.15) points,(2.88 ±1.67)points,(1.85 ±1.31)points,respectively.The postoperative ODS scores of the two groups of patients were compared with the preoperative decreased significantly (t =20.666,23.904,26.127,26.401,all P <0. 05;t =22.882,24.081,24.032,25.015,all P <0.05),but at 1 week after operation of the two groups of ODS score had no statistically significant difference (P >0.05);1 month,3 months and 6 months after surgery,the differences of ODS score of the two groups were statistically significant(t =2.313,3.585,323.3,all P <0.05).The depth of recto-cele in the observation group was (33.09 ±6.79)mm before treatment,(5.54 ±1.96)mm 1month after treatment and (6.67 ±1.95 )mm 6months after treatment;while (33.57 ±6.46)mm,(7.65 ±2.11 )mm and (9.32 ± 2.74)mm in the control group,respectively.There was no difference between the two groups in the depth of rectocele before treatment (P >0.05).After treatment,they were all significantly decreased (t =21.779,20.646,all P <0.05;t =25.261,20.768,all P <0.05)in the two groups,and compared with the control group,the observation group decreased more significantly(t =4.339,4.565,all P <0.05 ).The two groups of patients at months after the 6th month of the rectal protrusion were significantly higher than the 1st months after the surgery (t =2.864,3.113,all P <0.05).The incidence rate of side effects was significantly higher in STARR group than that in Sehapayak group 1st week after treatment (48.6% vs.22.9%,χ2 =5.040,P =0.025),but there was no difference in 6th month after treatment (8.1% vs.3.0%,P >0.05).Conclusion Compared with Sehapayak,improved STARR surgery has the advantage of excellent curative effects,less trauma,shorter hospitalization,less complications and higher patient satis-faction.Improved STARR surgery is conducive to the prevention of rectocele relapse.

Objective To explore the clinical treatment of Doppler guided hemorrhoid artery ligation (DG-HAL) combined with ultrasound-knife excision for severe hemorrhoids. Methods Eighty-seven patients with sever hemorrhoids were divided into 2 groups by the different admission months, the patients in group A (odd-numbered month) were treated by DG-HAL combined with ultrasound-knife excision, and the patients in Group B (bimonthly) were treated by procedure for prolaps and hemorrhoids. The clinical date were compared between 2 groups. Results There were no statistical differences in postoperative pain score and total efficient rate between 2 groups (P>0.05). The operating time, total hospitalization expenses and the incidences of postoperative bleeding, long term postoperative anal discomfort in group A were significantly lower than those in group B: (25.5 ± 2.8) min vs. (36.8 ± 4.6) min, (7 859 ± 564) yuan vs. (10 728 ± 733) yuan, 0 vs. 12.8%(5/39) and 2.1%(1/48) vs. 17.9%(7/39), the patient satisfaction score was significantly higher than that in group B: (9.3 ± 0.7) scores vs. (8.1 ± 0.6) scores, and there were statistical differences (P<0.05). Conclusions DG-HAL combined with ultrasound-knife excision to treat severe hemorrhoids has the definite treatment, less trauma, fewer complications and cheaper hospitalization expenses.

The strain of Cunninghamella echinulata 9980 was first selected with high aminoacylase activity . In three submerged cultures, the aminoacylase activity in the mycelial cell was compared . A number of factors have effects on the resolution reaction. The results showed that, peptone culture gave the highest aminoacylase activity with 680U/g.The optium temperature,pH,and substrate concentration were 55℃, 7.0,and 0.2mol/L,respectively. The ions in the buffer lowered the activity,but the Co~(2+) in 10~(-4)~10~(-3 )mol/L was necessary for its activity.
