Objective To explore the effect of LPLD (laparoscopic peritoneal lavage and drainage ) on SAP (severe acute pancreatitis), and to compare its effect with that of non- LPLD (conservative medical management). Methods We collected data from 87 consecutive patients with SAP, from January 2009 to May 2014, including LPLD group (n = 46) and non-LPLD group (n = 41). LPLD was performed in the 1st and 2nd week after the disease onset in LPDP group and other treatment in LPDP group was the same as that in non-LPLD group. Data were comparatively analyzed in two groups about the length of hospital stay, ICU stay, cure rate, incidence of complications and in-hospital mortality. Results In LPLD group, hospital stay, and ICU stay were shorter while cure rate was higher than those in non-LPLD group , and the difference was statistically significant (P < 0.05). In terms of the incidence of complications in two groups, only the incidence of sepsis indicated statistical significance (P < 0.05) and in-hospital mortality did not differ significantly between two groups (P > 0.05). Conclusion Compared with non-LPLD, LPLD is effective in short outcome, which is a promising treatment for SAP.

Objective:To discuss the result of treating valgus or varus knee deformity with fixator assist nailing (FAN)technique and distal femur osteotomy(DFO).Methods:In this retrospective study,14 patients with 17 limbs,12 valgus and 5 varus knee deformity were treated with DFO and FAN.The aver-age age of the patients was 23 (17-44)years .The unilateral external fixator was mounted on the lateral side of femur,the minimal invasive distal femoral osteotomy was performed.After the deformity was cor-rected,the intramedully nail was inserted to fix the femur.None of the patients need bone autograft.The preoperation and postoperation lateral distal femur angle (LDFA ),mechanical axis deviation (MAD ) and range of motion (ROM)were measured and analyzed.Results:All the 14 patients were followed-up for 12 -72 months (average 34 months).The osteotomy site united in 3 -5 months (average 3.5 months)post-operatively.According to Paley’s functional scores,12 patients were excellent,2 patients were good.We achieved desired postoperative MAD (from medial 15 mm to lateral 10 mm)in 15 limbs of 12 patients.The LDFA in 1 1 limbs was corrected to normal (84°-90°).The ROM was not signifi-cantly changed before and after operation in the both groups.No infection or neuro-vascular injury oc-curred.Conclusion:The FAN technique is an effective method to treat valgus knee or varus knee de-formity in young patients with DFO.

Rhynchosia volubilis Lour has been a major drug in a folk prescription for contraception in China, whereas its mechanism remains unknown. Its antifertility effects on male mice and antimicrobial activities on sexually transmitted infection (STI) pathogens were previously reported. This study was undertaken to develop the n-Butanol extract of Rhynchosia volubilis Lour (BERVL) as a spermicidal agent with STI prevention. The spermicidal activities of BERVL with different doses were assessed using selected high-motile sperms of normal human semen samples, and their inhibitory effects on Lactobacillus acidophilus were determined. The mechanism of the spermicidal activity was explored by aqueous Eosin Y and Hoechst 33342/PI staining. The results showed spermicidal activities and inhibitory effects of BERVL on Lactobacillus acidophilus were dose-dependent. Dose of 90 mg/mL BERVL terminated all progressive sperm motility within 2 min, and had slight inhibitory effect on Lactobacillus acidophilus, suggesting it was an effective and safe dose for contraception use. About 80% sperms exposed to BERVL displayed changes consistent with high permeability of head membrane. It is concluded that BERVL as spermicide has advantages over N-9 with strong ability to instantaneously kill human sperm and possesses light inhibitory effect on Lactobacillus acidophilus.

Objective To evaluate the effect of fixator-assisted nailing (FAN) technique for the treatment of femoral deformity,nonunion of femoral shaft fracture with deformity and malunion.Methods The data of 8 patients with nonunion of femoral shaft fracture with deformity,3 patients with femoral deformity caused by Rickets disease and 2 patients with femoral fracture malunion who received treatment FAN technique was retrospectively analyzed.There were 11 males and 2 females,with an average age of 33 years (range,16-50 years).One-stage operation was used in 10 patients:after the fracture was distracted and reduced with external fixator,an intramedullary nail was used for final fixation.Two-stage strategy was used in 3 patients.Unilateral external fixator was used in 12 patients,ring fixator was used in 1 patient.Femoral intramedullary nailing was used in 8 patients,retro-femoral intramedullary nailing was used in 5 patients; autograft from callus of fracture site was used in 1 patient.Results The 12 patients were followed up for 12-48months with an average of 21 months.The fractures of 7 patients united 3-6 months (average,3.9 months)later after the operation.The osteotomy site of 5 patients united 3-5 months (average,3.5 months) later after the operation.The results were evaluated according to the Paley classification of functional results.There were 9 cases rated as excellent,2 as good and 1 as fair.The lower leg discrepancy (LLD) before and after operation was (48.2±23.0) mm and (27.3±24.6) mm,individually; the length of limb increased 4.6-41.0 mm (average,23.3 mm).The pre-and post-operative MAD was (27.5±24.4) mm and (6.3±8.3) mm.There was no neurovascular injury or infection occurred in any of the patients.All the patients were satisfied with the result of treatment.Conclusion FAN technique combines the accuracy,minimal invasiveness and safety of external fixation together with patient compliance of IM nail.It is an effective method to manage nonunion of femoral shaft fracture with deformity,malunion of femur,and femoral deformity cause by rickets.

OBJECTIVE:To provide reference for rational drug use in the clinic. METHODS:The cases of disulfiram-like reac-tion collected from the First Affiliated Hospital of Guangzhou University of TCM from July 1st in 2012 to June 30st in 2014,were analyzed and compared retrospectively. The epidemiological characteristics,causes,clinical characteristics and treatment methods were summarized. RESULTS:Disulfiram-like reaction mainly occurred in male(86.59%),mainly in young and middle-aged men aged 21-50 years old (78.05%). It might be induced by using cephalosporin antibiotics (as cefoperazone,cefperazone/sulbactam, etc.),nitroimidazole (as metronidazole,tinidazole,etc.),drinking or contacting beverage,food or drug containing ethanol. This reaction involved the skin and its accessories system,circulatory system,digestive system,nervous system,respiratory system, etc. Its clinical manifestations mainly were skin flush,chest tightness,shortness of breath,palpitation,nausea,vomiting,dizzi-ness,headache,etc.,occasional confusion,drowsiness,xerostomia,etc. Response to the severe disulfiram-like reaction,the foun-dation treatment combined with symptomatic treatment showed a good effect with remission of symptoms in 1 to 3 hours and no deaths. CONCLUSIONS:When the drugs with mercapto-1-methyltetrazole perssad as cephalosporin antibiotics,nitro imidazoles, etc.,are used,we should avoid drinking or taking drugs or food containing ethanol,to prevent the occurrence of disulfiram-like re-action.

Objective To explore if continuous administration of adenosine by peripheral pathway can attenuate myocardial hypertrophy and pulmonary arterial hypertension(PAH)caused by chronic hypoxia and analyze the dose-effect relationships between them.Methods Forty-eight Sprague-Dawley(SD)rats were randomly divided into 8 groups:the hypoxia group(n=6),the hypoxia ade-nosine-treated groups [n=18,adenosine was administrated with different doses 50,100,150 ?g/(kg?min),the hypoxia adenosine-treated group A,B,C],the control group(n=6),the control adenosine-treated control groups [n=18,adenosine was administrated with different doses 50,100,150 ?g/(kg?min),the control adenosine-treated control group A,B,C].On the 21st day of the experiment,the Medlab-U/4CS was used to determined the right ventricular systolic pressure(RVSP)and the mean pulmonary arterial pressure(mPAP)of each rat.The ratio of the weight of right ventricle/left ventricle and septum[RV/(LV+S)] and the ratio of the weight of right ventricle/body weight(RV/BW)were also calculated.The morphological changes in myocardium cells and pulmonary vascular structure were observed.SAS 8.0 software was used to analyze the data.Results Twenty-one days after hypoxia,RVSP,mPAP,RV/(LV+S),RV/BW in hypoxia groups were higher significantly than those in control group and hypoxia adenosine-treated groups(Pa

BACKGROUNDOlder subjects tend to have smaller ocular anterior segment. The present study aimed to measure anterior segment dimensions with optical coherence tomography (OCT) and quantitatively assess the effect of age and other factors.

METHODSAnterior segment OCT images were obtained in normal subjects residing in the greater Los Angeles area. Four line scans were acquired at the 90°, 45°, 0° and 135° meridians of each eye. Computer calipers acquired anterior segment dimensions of corneal diameter, anterior chamber width, corneal vault and anterior chamber depth on OCT images. Measurements from 4 meridians were averaged. Axial length and corneal power were measured by partial coherence interferometry. Univariate and multivariate analyses were performed to assess correlations.

RESULTSSixty-six eyes of 33 normal subjects (aged 22 - 65 years, 19 Asians, 14 Caucasians) were enrolled. For every 1 year of age, corneal diameter was 0.033 mm narrower (P < 0.01), anterior chamber width was 0.031 mm narrower (P < 0.01), corneal vault was 0.016 mm lower (P < 0.01), and anterior chamber depth was 0.025 mm lower (P < 0.01). Asian eyes had smaller corneal diameter (P = 0.035) and anterior chamber width (P = 0.015) compared with those of Caucasian eyes. Body height showed positive correlation with corneal diameter (0.039 mm per centimeter of height, P < 0.01) and corneal vault (0.024 mm per centimetre of height, P < 0.01). Gender did not have an independent effect on anterior segment dimensions.

CONCLUSIONSAnterior segment dimensions were smaller in older subjects. Age-related changes may affect the tolerability of long-term implants such as phakic intraocular lens.
