OBJECTIVE:To evaluate the efficacy of methotrexate(MTX) vs.gold salt in treating patients with rheumatoid arthritis(RA).METHODS:7 studies on the efficacy of methotrexate(MTX) vs.gold salt in treating patients with rheumatoid arthritis(RA) were subjected to a meta-analysis using homogeneity test and combined effect test.RESULTS:Homogeneity test showed that the cited studies were homogeneous with ?2=25.14,df=6 and P=0.0003;and by combined test,the combined OR was 2.37(95% confidence interval=1.18～4.78,Z=2.41,P=0.02).CONCLUSION:Methotrexate demonstrated better toleration than gold salt for rheumatoid arthritis.

Objective To investigate the effect of folic acid on the DNA methylation of tumorrelated genes promoters in healthy human peripheral blood mononuclear cells(PBMC). Methods Ten healthy volunteers were divided into two groups, and were randomized to receive either 5 mg folic acid (n=5)or placebo(n = 5) , one time per day for 3 months. The serum folic acid concentration was detected with chemiluminescence enzyme immunoassay kit before and after the intervention. The methylation statuses of five tumor-related genes promoter, including oncogenes c-myc, c-Ha-ras,tumor suppressor genes p16INK4A, E-cadherin and mismatch repair gene hMLH1 in PBMC were detected by bisufite sequencing. Results After folic acid intervention, the level of serum folic acid increased significantly in intervention group (t= -4. 739,P<0. 05) , however no significant difference in control group. After three-month folic acid intervention, the level of methylation of oncogene c-myc promoter increased from 4%, 3. 3%, 4. 1% before intervention, one week after intervention, one month after intervention respectively to 8%(t= -4. 079,P<0. 05), while no significant change in placebo taken group. Before and after the folic acid intervention, there was no significant difference of DNA methylation of other tumor-related genes promoter, including c-Ha-ras、E-cadherin、p16INK4Aand hMLH1. Conclusion Folic acid intervention can up-regulate DNA methylation of oncogene c-myc promoter, but can not affect the promoter methylation status of tumor suppressor genes E-cadherin,p16INK4Aand hMLH1.

OBJECTIVE:To observe therapeutic efficacy and safety of Danshen chuanxiongqin injection combined with flunari-zine hydrochloride in the benign prevention and treatment of paroxysmal positional vertigo (BPPV) and lower extremity deep ve-nous thrombosis (DVT) in post-operative long-term bedridden patients with lower limb fractures. METHODS:300 post-operative long-term bedridden patients with lower limb fractures were selected and randomly divided into observation group and control group,with 150 cases in each group. Control group was given Flunarizine hydrochloride capsules orally 10 mg,qd;observation group was additionally given Danshen chuanxiongqin injection 10 ml+5% Glucose injection 250 ml,ivgtt,qd. The incidence of BPPV and DVT were observed in 2 groups after intervention,and the circumference of lower limb,blood coagulation indexes, blood rheology indexes and inflammatory factor were observed before and after intervention,and the incidence of ADR was com-pared. RESULTS:The incidence of BPPV and DVT in observation group were 18.0% and 16.7%,which were significantly lower than in control group(48.7% and 52.7%),with statistical significance(P<0.05);after intervention,the circumference of lower limb,blood rheology indexes and the levels of inflammatory factors in 2 groups were decreased significantly, while the coagula-tion indicators were significantly improved;the observation group was better than the control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Danshen chuanxiongqin injection combined with flunarizine hydrochloride is effective in the prevention of BPPV and DVT in long-term bed-ridden patients with lower limb fractures,with low incidence of ADR.

Objective To improve the effect of clinical diagnosis and treatment of acetabular fracture with a femoral nerve injury by analyzing the causes of femoral nerve injury following acetabular fractures.Methods From January 1996 to November 2004,146 cases of acetabular fractures were treated operatively.Six cases of them were complicated with femoral nerve injury.The causes of femoral nerve injury were analyzed on the basis of clinical manifestations,CT scan and 3-dimensional reconstruc- tion.All the cases were classified according to Letournel and Judet classification.Three cases had hema- toma compression (2 cases with double column fractures and 1 with transverse-posterior wall fractures);2 cases had femoral nerve injury caused by fracture fragments (1 case with anterior wall fracture following anterior hip dislocation,the another with old fracture of anterior column combined with fracture of superior ramus of pubis);and one case had anterior column fracture combined with fracture of wing of ilium,and the femoral nerve was injured by traction in operation.Clearance of hematoma,nerve tract decompression and epineuria solution were performed in 5 cases,and 1 case was treated conservatively.Results The average follow-up period was 1.8 years(ranging from 1 to 3 years).The muscle power of quadriceps fem- oris recovered from 1-2 grade before operation to 4-5 grade after operation in 5 cases.The function of ex- tensor knee and gait was normal.The function of sensory completely recovered in 4 cases.One case was followed up for 2 years,which showed the patient still suffered from hypoesthesia in the lower 2/3 of the thigh and the medial of the leg.One ease of traction injury was followed up for 1.2 years,showing the muscle power recovered to normal,but still presented with sensory disability.Conclusion Acetabular fractures associated with femoral nerve injury are rare.For complex acetabular fractures and severe trau- ma,attention should be given to the possibility of femoral nerve injury.Fragment stabbing and compres- sion of hematoma around iliopsoas muscle are the common causes of femoral nerve injury following ace- tabular fractures.Iatrogenic injury should not be ignored.

[ ABSTRACT] AIM: To observe the effect of circadian rhythms on wound healing of mouse corneal epithelium. METHODS:The C57BL/6 male mice were used in the study.A part of corneal epithelium (2 mm in diameter) was struck off by a golf-like knife to form a round wound area.The dynamics of epithelial healing in the wound area were ob-served under microscope with fluorescein staining.In addition, with related antibodies and DAPI, the dynamic changes of the neutrophils, platelets and dividing cells were also investigated.RESULTS:The healing rates in LL group (12 h light/12 h light) and DD group (12 h dark/12 h dark) were obviously slower than that in LD group (12 h light/12 h dark), mainly showing delayed re-epithelialization, decreased epithelial cells, increased diameter of blood vessel, and delayed re-cruitment of neutrophils and platelets, but more cell number.CONCLUSION:Disruption of circadian rhythms significant-ly inhibits the wound healing of corneal epithelium, mainly through delaying the inflammation and re-epithelialization, but aggravating the inflammatory responses.

Objective:To analyze the structure modes of general practice teams in community health care cen-ters in order to provide empirical evidence for the transformation of the community health service mode. Method:Pur-posive sampling was adopted. Twelve community health service centers in Beijing, Shanghai, Zhengzhou and Cheng-du, where the transformation of the community health service mode was piloted earlier and representative, were se-lected as the field survey sites. The qualitative method was used to collect the data accompanied by the quantitative method. Results:The structure models of general practice teams could be divided into four types:1) general practi-tioner+nurse+nurse assistant+pharmacist, 2) physician (general practitioner, herbalist physician) +nurse+com-munity volunteers, 3 ) physician ( general practitioner/herbalist physician ) +nurse +assistant +community volun-teers, and 4) general practitioner+nurse+assisting team (professionals of public health and maternal care, etc) +supportive team ( pharmacists, health technician, etc) . Conclusion:The paper verified the common sense conclusion that general practitioners should play an essential role in general practice teamwork. The four general practice team models analyzed above positively contributed to the improvement of efficiency and quality, the relationship between health professionals and patients, the promotion of community participation, and the combination between preventive care and clinical care.

This study was aimed to investigate the genetic characteristics, identification method and transfusion strategy of rare blood type B(A). The rare blood group B(A) was typed by serological technique, PCR-SSP genotyping and sequencing of exon 6, 7 of ABO blood group. The genetic characteristics and molecular mechanism of B(A) blood group were also analyzed. Blood group compatibility test was conducted between blood donors of B(A) and recipients by clinical transfusion. The results showed that both forward and reverse grouping did not match the 3 cases of serological result in their family survey, while all of the 3 cases were grouped as AB blood group by forward grouping, B blood group by reverse grouping with serological result and B(A)04/001 group were genotyped by ABO genotyping. The patient of B blood group was transfused by 1 bag of washed red blood cells of donor of B(A) under closely monitoring, the patient's condition changed, and a mild adverse transfusion reaction was appeared. Washed red blood cell of O blood group was transfused into B(A) patient without blood transfusion reaction. It is concluded that the forward ABO serological grouping and reverse ABO serological grouping are not compatible, that may be verified by family survey and molecular biological methods. If in some cases transfusion therapy was applied, and group B(A) can not be transfused to the patient with group B or AB. Thus, transfusion compatibility or autologous transfusion can be adopted to transfuse to the patient from group B(A).

BACKGROUNDThe research of cancer in patients on hemodialysis (HD) in China has not been reported. The aim of this study was to investigate the clinical and histological features and outcomes of cancer in Chinese HD patients.

METHODSThe study subjects were 49 cancer patients (1.4%) out of 3448 end stage renal disease (ESRD) patients maintained on HD at China-Japan Friendship Hospital from October 1997 to July 2011.

RESULTSUrinary tract cancer (74%) was the most common followed by gastrointestinal tract cancer (12%), breast cancer (6%), lung cancer (4%), thyroid cancer (2%), and hematologic cancer (2%). Thirty-three patients (67%) had urinary tract transitional cell carcinoma (TCC) and 29 of them had aristolochic acid nephropathy (AAN) as underlying disease. Death occurred in eight patients out of 49, and the survival rate of HD patients with cancer was similar to those without cancer (P = 0.120).

CONCLUSIONThe urinary tract TCC is the most common cancer in HD patients with AAN in one of the centers of northern China.

OBJECTIVESTo measure continuously the urine beta-FSH excretion in the patients with male hypogonadism, and to evaluate the significance of urine beta-FSH when used in the clinical practice and pathophysiological study on male hypogonadism.

METHODSFour health male volunteers (aged 19, 22, 27 and 33 years), four patients with the hypogonadotropic hypogonadism (aged 17, 17, 19 and 24 years) and five patients with idiopathy hypogonadism (hypergonadotropic, aged 16, 16, 17, 20 and 22 years) were asked to collect their morning-first urine samples for 30 to 32 days. One normal men collected his urine samples for 63 days. The urine beta-FSH was assayed with the method of EIA, then corrected by creatinine (Cr) concentration.

RESULTSThe urine beta-FSH level of normal men was (1.16 +/- 0.20) micrograms/mg Cr, with the peak variation in their curves, peak level at 2.76 micrograms/mg Cr. The levels of urine beta-FSH of 4 patients with the hypogonadotropic hypogonadism were lower significantly than those of normal men [(0.58 +/- 0.31) (0.93 +/- 0.47) (0.47 +/- 0.33) and (0.60 +/- 0.40) micrograms/mg Cr], without fluctuation in their curves. beta-FSH levels of 5 patients with idiopathy hypogonadism were higher significantly [(3.02 +/- 0.93), (4.36 +/- 1.12), (4.79 +/- 0.78), (4.64 +/- 1.42) and (3.88 +/- 1.42) micrograms/mg Cr], with irregular fluctuation, the highest peak level at 6.83 micrograms/mg Cr. The second sexual characteristics of hypogonadal patients were poor and serum testosterone levels low.

CONCLUSIONSThe urine beta-FSH level raised with irregular fluctuation in patients with idiopathy hypogonadism, while lowed without any fluctuation in patients with the hypogonadism. These findings suggested that the urine beta-FSH excretion was useful for the clinically classified diagnoses and pathophysiological study on male hypogonadism, and for observing the treatment reaction of androgen replacement.
