Preterm birth is the main factor affecting the lives and quality of life for premature infants,which is also the main cause for a large economic burden on family,society and medical system.It has been confirmed that the bad neurodevelopment outcome can be effectively prevented by early intervention programs,which are including therapeutic developmental interventions targeting the infants,as well as psychosocial support and education for parents.This review summarizes early intervention programs for improving developmenr outcome in recent years.

Debates over PBL have never stopped since its introduction to medical education in 1969 and are even becoming more heated.This paper expounds on the origin and definition of PBL,and then describes and analyzes the application of the clinical teaching in orthopedic surgery.

Objective:To study the preventive effect of drinking green tea on serum lipids and obesity of middle aged people. Method:Total of 3 317 middle-aged people were ascertained by a questionnaire, and their serum lipids were measured at their health examination. Results:Consumption of green tea significantly decreased serum total cholesterol (P

Objective To investigate the pathological change in articular cartilages after firearm injury.Methods Four rabbits from 28 New Zealand healthy rabbits were chosen as control group and subjected to joint capsule incision only. Another 24 rabbits were equally divided into 6 experimental groups( groups B to G) and subjected to medial femoral condyle cartilage surface damage by the nail gun.After the operation, their specimens were collected after 6 h,3 d,7 d,14 d,28 d and 56 d, respectively.Tissue sections were observed and stained by HE staining and toluidine blue staining.The histolopathological changes in articular cartilage after firearm injury were detected.Results The color of articular cartilages in experimental groups became lighter, the cell number increased but then decreased, the articular cartilage layer disappeared, the cell shape became uneven, cells began to cluster and the Mankin score increased, and the statistical differences between experimental groups and control group were significant.Conclusion The histological pathological changes in articular cartilages after fiream injury seem to follow some pattern.The degeneration seems obvious after 7 days and then becomes heavier.

Objective To compare sodium supplement and sodium restriction to the effect of the extinction and prognosis of liver cirrhosis ascites, and research the relationship between live cirrhosis ascites and plasma sodium.Methods 119 liver cirrhosis patients were randomly divided into 2 groups :60 cases of sodium supplement and 59 cases of sodium restriction. 60 cases of sodium supplement was kept low-salt diet and intravenous sodium chloride supplement(3 ～5 g/d) ,59 cases of sodium restriction was only kept low-salt diet. Plasma sodium,plasma chloride,urine sodium, urine sodium chloride were detected before treatment, and 6 days, 10 days after treatment respectively. And the urine quantity,extinction of ascites and prognosis were compared. Results There were significant differences on the increase of plasma sodium,plasma chloride,urine sodium,urine chloride and urine quantity after treatment in two groups. Extinction time of ascites was shorter in group of sodium supplement. The morbidity and fatality rate of hepatic encephalopathy, and hepatorenal syndrome in the group of sodium supplement were lower than that in the group of sodium restriction. Conclusion Sodium supplement should be adapted when using diuretic agent to help the extinction of ascites, and to improve recovery.

An LC-MS/MS method was developed to investigate the pharmacokinetic parameters in healthy Chi-nese volunteers following single and multiple oral administration of dimemorfan phosphate. In the Single-dose study,two-period and crossover study was conducted in 12 healthy volunteers,which were administered with single-dose of 10 mg or 40 mg of dimemorfan phosphate. And another 12 volunteers were administered with 20 mg. The values of AUC0-48 h,t1/2,and cmax were (11. 81 ±14. 46),(52. 60 ±96. 01 )and (34. 70 ±29. 59)ng. h/mL,(12. 11 ±2. 54),(12. 16 ±2. 01)and (12. 77 ±1. 27)h,and (0. 9653 ±0. 8178),(3. 150 ±3. 451)and (2. 167 ±1. 650)ng/mL for 10 mg,40 mg and 20 mg oral administration. The same 12 healthy volunteers as the group of single-dose of 20mg were participated in multiple-dose study,which were administered dimemorfan phos-phate 20 mg,three-time a day until the day-8,showed AUC0-48 h,t1/2,and cmax were (115. 9 ±135. 2)ng.h/mL, (11. 22 ±1. 61)h,and (7. 418 ±7. 010)ng/mL. The accumulation parameter Rcmax and RAUC was (3. 14 ±1. 34) and (3. 38 ±1. 22),respectively. Dose proportional of cmax and AUC was not concluded ranging from 10 mg to 40 mg after confidence interval criteria method. An accumulation was occurred after multiple -dose administra-tion with the consequence. And the results demonstrated significant individual difference.

As a crucial part of the DNA damage repair process,the expression of excision repair cross-complementing group 1 (ERCC1 )is closely related to the genesis and development of gastric cancer.Studies find that ERCC1 gene polymorphism can alter the expression of the gene itself,which affects the sensitivity and efficacy of platinum-based chemotherapy.Therefore,the detection of ERCC1 polymorphism may guide the indi-vidualized chemotherapy of the patients with gastric cancer.

Objective To evaluate the effectiveness of discharge planning and home care for patients with peritoneal dialysis (PD).Methods A total of 60 PD patients were randomly divided into the intervention group and control group,30 cases in each group.Discharge planning and home care were carried out in the intervention group, while routine nursing and telephone follow -up service after discharge were implemented in the control group.The patientsˊscores of Zung Self -Rating Anxiety Scale(SAS),Self -Rating Depression Scale(SDS),Self management ability of patients undergoing peritoneal dialysis,complication rate and readmission rate were compared between the two groups at the next day admission,discharge,lth month and 3th after discharge.Results The scores of SAS and SDS in the intervention group were significantly lower than that in the control group at 3th month after discharge,the difference was statistically significant(tSDS =5.263,tSAS =3.812,P <0.05).The Self management ability of patients undergoing peritoneal dialysis was significantly higher than that of the control group at lth and 3th month after discharge,the difference was statistically significant (t =6.845,t =7.231,P <0.05).No significant difference in the re -admission rate (16.67%,6.67%)was found between the two groups (χ2 =0.387,P >0.05).The complication rate in the intervention group was significantly lower than in the control group at 3th month after discharge(χ2 =5.124,P <0.05).Conclusion Discharge planning and home care can effectively relieve depression and anxiety in patients with peritoneal dialysis and improve the abilities of daily life.It is worth promoting and applying in clinic.
