From the practice of application of PBL teaching in biochemistry,we find that the PBL has obvious advantages in inability training,class course and knowledge application,but the PBL should be applied in limited theory-learning course.

Objective To discuss the correlation between tyre bursting and traffic accidents on highways. Methods A retrospective statistical analysis was carried out on traffic accidents resulted from tyre bursting on the Guangzhou-Shenzhen highway from 1998 to 2000. Results During three years, there occurred 2 484 cases of traffic accidents on the Guangzhou-Shenzhen highway, of which 848 cases resulted from tyre bursting, accounting for 34.14% (848/2 484). During a day, incidence from 10:00 to 16:00 was 55.54% (471/848), which was higher than that in any other time, and the highest incidence was at 14:00, accounting for 9.67% (82/848). During a year, incidence from April to September was 56.84% (482/848), higher than that in any other months. Considering the tyre factor, accidents resulted from burst of single right posterior tyre were 398 cases, occupying 46.93% (398/848) of the total, which was more than those resulted from burst of any other tyres. The second dangerous burst position was on the left posterior tyre, from which accidents reached 295 cases occupying 34.79% ((295/848)) of the total. Of all, 848 cases of tyre bursting accidents resulted in 12 deaths and 200 injuries, which accounted for 22.55% of the total death and wound (212/940). There were 58 cases of craniocerebral trauma, 32 chest trauma, seven abdominal injuries, 25 spinal cord injuries, four pelvic injuries, 52 branches injuries, 127 soft tissue injuries all through the body and 106 combined injuries. Conclusions Tyre bursting is a vital factor for traffic accidents on highways of South China. In order to effectively reduce traffic accidents on the highways, we must prevent overspeed driving, strengthen the regular check of the tyres and normalize corresponding management.

Objective To study the relationship of intestine permeability with post hepatitis cirrhosis. Methods Serum DAO levels were measured by Holt method and lactulose/mannitol absorption tests were performed in 96 patients (Child A, n =11; Child B, n =37; Child C n =48) with post hepatitis cirrhosis and 49 healthy control subjects to evaluate the intestine structure and function of the patients. Lactulose and mannitol levels in 5 hours urine were determined by gaschromatographic assay. Results DAO activity and lactulose/mannitol ratio were higher in each patient group than those in normal control group (DAO Child A 4.68?0.97, Child B 6.05?1.02, Child C 7.80?1.34 vs 3.98?0.93, P

Objective To evaluate ocular surface changes following minimal vitreoretinal surgery in postmenopausal women patients with proliferative diabetic retinopathy (PDR).Methods Sixty-one women PDR patients (61 eyes) underwent vitreous microsurgery were recruited in this prospective study,including 31 postmenopausal women (PMW group) and 30 non-postmenopausal women (non-PMW group).The contralateral eyes were considered as the control group.Corneal fluorescein (FL) staining,tear break-up time (TBUT),Schirmer I test (SIT),central corneal sensitivity and ocular surface disease index (OSDI) were estimated.All tests were carried out 1 day preoperatively and 1 day,10 days,1 month and 3 months postoperatively.The student's t test or Mann-Whitney U and ANOVA for repeat measurements test were used.Results Preoperatively,TBUT of surgery and non-surgery eyes in PMW were shorter than non-PMW (t=-2.115,-2.035;P＜0.05),but higher OSDI scores were found in PMW (t=2.482,2.208;P＜ 0.05).TBUT reduction rate (Z=-2.771,-1.993;P＜0.05) and OSDI rising rate (Z=2.539,2.157;P＜0.05) of surgery eyes in PMW were higher than non-PMW 1 day and 10 days postoperatively.The lower SIT of surgery eyes in PMW were observed at 1 day and 10 days (t=-2.403,-2.029;P＜0.05) after surgery.At 10 days after surgery,FL and OSDI scores of surgery eyes in non-PMW returned to preoperative level (Z=-0.447,-0.513;P＞0.05),but in PMW,the recovery process experienced 1 month (Z=-1.500,-0.853;P＞0.05).TBUT and SIT of surgery eyes in two groups both reached preoperative level at 1 month following surgery (Z=-0.715,-1.266,-1.531,-0.522;P＞ 0.05).Conclnsions PMW with PDR had ocular surface dysfunction,which resulted in aggravated dry eye after minimal vitreoretinal surgery.

Objective To analyze the current situation of institutional care for people with disabilities in Shanghai, China. Methods Sec-ondary data were collected from the synthetical information platform of Shanghai Disabled Persons' Federation, including data about the res-idential institutions and people with disabilities living in the institutions from 2004 to 2015. Results The number of residential institutions and people with disabilities showed an increasing tendency from 2004 to 2015. At the end of 2015, there was 368 residential institutions in Shanghai, providing institutional care for 5821 people with disabilities. People in the institutions were mainly with intelligence disability and mental disability, and mainly in 35 to 59 years old. Conclusion The institutional care for people with disabilities was generally in a good condition in Shanghai and met people's needs.

This paper aims to investigate the regulatory mechanism of blood-activating and stasis-dissipating drugs on fecal metabolic characteristics of rhubarb-peach kernel in mice with adenomyosis (AM) using fecal metabolome method. Adenomyosis was modeled by pituitary transplantation, and after the end of modeling administration, fecal samples were collected from mice. Non-targeted metabolomics studies were performed using liquid chromatography-mass spectrometry (LC-MS) to compare the metabolic characteristics of the feces of mice in each group and to find intestinal differential metabolites and potential differential metabolic pathways. The results showed that compared with the normal group, 5-hydroxy-L-tryptophan, histidine, L-acetylcarnitine, 16-hydroxy hexadecanoic acid, thromboxane B₂, etc. were significantly up-regulated, L-urobilin and prostaglandin D₃ were down-regulated in the feces of the model group, and were reversed after treatment with the rhubarb-peach kernel. The results of metabolic pathway enrichment analysis showed that tryptophan metabolism and histidine metabolism were the main intervention pathways of the rhubarb-peach kernel on AM intestinal metabolism. This study found that the underlying mechanism of the rhubarb-peach kernel in the treatment of AM is related to the intervention of intestinal metabolism of tryptophan, histidine, bile acid, choline and arachidonic acid, and the regulation of pro-inflammatory microenvironment and fatty acid metabolic homeostasis. This study has been approved by the Experimental Animal Ethics Committee of China Three Gorges University (No. 20190801).

OBJECTIVETo explore the clinical effects of internal fixation with lag screws plus an anti-sliding plate for the treatment of Hoffa fractures of the lateral femoral condyle.

METHODSFrom May 2006 to May 2014, 17 patients with Hoffa fractures of the lateral femoral condyle were treated with lag screws plus an anti-sliding plate. There were 13 males and 4 females, ranging in age from 27 to 59 years, with a mean of 32.5 years. All the fractures were fresh and closed fractures. According to the Letenneur's classification, 8 cases were type I, 4 cases were type II, 5 cases were type III. All the patients had no injuries of the cruciate ligament and the another part of the knee. Operative incision and fracture healing time were observed, knee joint function was evaluated by Letenneur system and HSS standard.

RESULTSThe patients were followed up from 10 to 24 months with a mean of 14.6 months. All incisions achieved primary healing, and no internal fixation breakage, malunion, femoral candyle necrosis, deep vein thrombosis of lower extremity were found. Fracture healing time was from 4 to 9 months with an average of 4.7 months. According to Letenneur's functional assessment, 10 patients got an excellent results, 4 good, 3 fair. Total HSS score was 91.1 +/- 4.7 on average,15 cases obtained excellent results, 2 good.

CONCLUSIONInternal fixation with lag screws and an anti-sliding plate can result in excellent effects for Hoffa fractures of the lateral femoral condyle. The key to a successful surgery is an anatomic reduction and rigid fixation of the fracture.
