0.05). The pathological change in myocardial ultrastructure was markedly milder in DM rats. Conclusion Metformin may exert a certain protective effect on cardiomyopathy of diabetes in rats.

Objective To observe the effect of puerarin on the expression of NF-?B65 and TNF-? in kidney of diabetic rats. Methods SD rats were randomly assigned to 5 groups (10 each):normal control group (group A),diabetic group (group B),low-dose,middle-dose and high-dose treatment groups (group C,D and E). After diabetes model was reproduced,animals in group C,D and E were i.p. injected with puerarin in a dose of 40,80 and 160mg/(kg?d),respectively; animals in group A and B were treated with corresponding normal saline. Fasting blood glucose (FBG),urinary albumin excretory rate (UAER),serum creatinine (Scr) and blood urea nitrogen (BUN) were determined at the 8th weekend after treatment. The histological changes in renal cortex were observed with light microscope and electron microscope. The qualitative and semi-quantitative expressions of NF-?B65 and TNF-? in nephridial tissue were determined by immunohistochemical method. Results FBG,UAER,Scr and BUN were higher in group C,D and E than that in group A (P

Objective To investigate the clinical efficacy of Xi-Cleft point acupuncture plus surrounding electro- acupuncture in treating occipital neuralgia.Methods Forty-eight patients with occipital neuralgia were randomly allocated to treatment and control groups, 24 cases each. The treatment group received Xi-Cleft point acupuncture plus surrounding electroacupuncture and the control group, surrounding electroacupuncture alone. The VAS score was recorded in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There was a statistically significant pre-/post-treatment difference in the VAS score in the two groups (P<0.05). There was a statistically significant post-treatment difference in the VAS score between the treatment and control groups (P<0.05). The total efficacy rate was 95.8% in the treatment group and 83.3% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Xi-Cleft point acupuncture plus surrounding electroacupuncture is an effective way to treat occipital neuralgia.

Objective:To explore the expressions of the nuclear factor-?B(NF-?B),C- myc and ICAM-1 in human colon and rectal cancer and the relationship between NF-?B and the occurrence,the metastasis of human colon and rectal cancer.The clinical significance was analyzed.Methods:Fifty human colon and rectal cancer cases ,16 colon and rectal adenomas,9 carcinomatous change of colon and rectal adenoma and 8 normal colon were studied,the expressions of NF-? Bp65,C- myc and ICAM-1 in them were examined by immunohistochemical method.Results:NF-?Bp65,C- myc were strongly expressed in the colon and rectal cancer and carcinomatous change of colon and rectal adenomas than those in colon and retal adenoma;C- myc could not express in normal colon;NF-? Bp65 and C- myc were significantly positive correlation with colon and rectal cancer;NF-?Bp65,ICAM-1 were strongly expressed in the colon and rectal cancer which had metastasis than those had no metastasis,and they had striking positive correlation with colon and rectal cancer which had metastasis.ConclusionTo control the transcription of C- myc and ICAM-1,NF-?B plays an important action in the occurrence and metastasis of colon and rectal cancer.It will become a new target of treatment of colon and rectal cancer.

Objective To study the changes of six sex hormones corresponding to the follicle growth during the normal menstrual cycle of Chinese women.Methods Thirty Chinese women with regular menstrual period and average age of (28.8±3.2) years were selected for the study by Peking Union Medical College Hospital in September,2010.Growth of follicles was monitored by using transvaginal sonography.Six sex hormones,including follicle-stimulating hormone (FSH),luteinizing hormone (LH),estradiol (E2),progesterone (P),testosterone (T),and prolactin (PRL) were measured by chemoluminescence immunoassay every day during a menstrual cycle.Nonparametric statistical analysis was used.ResultsMenstrual cycle of all the patients was in the range of 25 to 39 d,with mean of (29.5 ± 3.1) d.Length of follicular phase and luteal phase was 15.3 and 14.4 d,respectively.Number of days from antral follicle to emergence of dominant follicle,and from the latter to ovulation,was 6.2 and 8.9 d,respectively.Average diameter of preovulatory follicle was 19.33 mm.Both FSH and LH reached peak on the day before ovulation.P started to increase before ovulation and remained at a high plateau from 6th to 9th day after ovulation.Both PRL and T reached peak after ovulation,near the end of a menstrual cycle.Conclusions A small rise of LH and P emerges just 1 to 2 d before ovulation,indicating the maturing of follicle.PRL and T shows cyclic changes as follicle grows.Therefore,PRL and T levels should be measured in the early follicle phases in the clinical practice so that leading the impact of menstrual cycle minimal.

Objective:To evaluate the effects of perioperatively administrated enteral immunonutrition in gastrointestinal cancer patients on immune and inflammatory responses,nutrition states and postoperative morbidity.Methods:Sixty patients with gastrointestinal cancer were divided randomly into two groups.Two groups perioperatively(from preoperative day 5 to postoperative day 7) received an supplemented diet with arginine,RNA,and ?-3fatty acids(immunonutrition group;n=30) or an isoenergetic and isonitrogenous standard diet (standard-nutrition group;n=30).All variables of immune and inflammatory responses,nutrition states and postoperative morbidity were measured on preoperative day 5 and postoperative day 1,4 and 8.Results:On postoperative day 4 and 8,most immune variables and prealbumin in the immuno-group were significantly higher than those in the standard-group(P0.05),and inflammatory variables as CRP in the immunonutrition group were significantly lower than those in the standard group.In the immunonutrition group,there were significantly fewer patients who experienced postoperative complications and shorter days of hospital stay compared with standard group(P0.05).Conclusion:The perioperative administration of enteral immunonutrition in gastrointestinal cancer patients can significantly modulate the postoperative immunosuppressive and inflammatory responses at the early postoperative day,can significantly decrease the occurrence of infectious and overall postoperative complications as well as the length of hospital stay.

Objective To justify the clinical use of traditional Chinese materia medica (TCMM) in the treatment of influenza.Methods The literature on treatment of influenza published before December 31, 2013 was searched in MEDLINE, EMBASE, CBMdisk, Chinese National Knowledge Infrastructure (CNKI) and Wanfang Database.Results A total of 7 randomized controlled trials were identified and reviewed. Based on the meta-analysis, Yinqiao Powder prescription had similar effect to oseltamivir in defervescence [WMD=5.66, 95%CI (-32.02, 43.35), P=0.77] and viral shed-ding [WMD=-6.21, 95%CI (-84.19, 71.76), P=0.88], and Lianhuaqingwen also had similar effect in viral shed-ding [WMD=-0.24, 95%CI (-4.79, 4.31), P=0.92] but was more effective in defervescence [WMD=-4.65, 95%CI (-8.91, -0.38), P=0.03].Conclusion TCMM has a potential positive effect in the treatment of influenza.

ObjectiveTo analyze the effect of Tetrandrine (Tet) on neuronal apoptosis and reletted gene expression after acute spinal cord injury (ASCI) in SD rats so as to provide experimental basis for treatment of ASCI.MethodsA total of 95 adult SD rats were.randomly divided into four groups,ie,control group ( n =5 ),ASCI group ( n =30),Tet treatment group ( Tet group,n =30) and methylprednisolone treatment group ( Mp group,n =30).The ASCI model was established with the aid of modified Allen method.The five rats from each group were sacrificed at postoperative 8 hours and 1,3,7,14,21 days respectively to observe the morphology of the injury spinal cord and expressions of cell apoptosis regulation genes ( Bcl-xl,Bcl-xs).The flow cytometry ( FCM ) was used to semiquantitatively analyze the apoptotic cells. ResultsExcept for the control group,the other three groups had morphological changes.Tissue edema,neuronal degeneration with some necrosis and marked inflammatory cell infiltration were founded in the ASCI group.Tissue injury was alleviated in the Tet group and was relatively much milder in the Mp group,with no obvious necrosis or inflammatory cell infiltration.Except for the control group,the number of Bcl-xs positive cells at the same time point was the most in the ASCI group in comparison with the Tet and Mp groups.Meanwhile,the expression of Bcl-xl in all groups reached the peak at day 7 post-injury.The semiquantitative analysis of the apoptotic cells displayed that,except for the control group,the number of apoptotic neurons in other three groups reached the peak at day 7 postinjury and then declined gradually.At the same time point,the apoptotic neurons in the Tet group were less than that in the ASCI group,but more than that in the Mp group. ConclusionsAfter ASCI,Tet plays an active role in intervening the expression of the apoptosis regulation gene and can evidently decrease neuronal apoptosis.Tet treatment can work within 7 days and should be given for ASCI as early as possible.However,Tet exerts weaker effect on ASCI in comparison with MP.

Objective To explore effects of atorvastatin on the expressions of cyclooxygenase-2(COX-2) and membrane-associated prostaglandin E2 synthase-1 (mPGES-1) in the carotid atherosclerotic plaques of rabbits.Methods Totally 33 male New Zealand white rabbits(≥ 36months of age ) were assigned into normal control group (n=8) and animal model group with carotid atherosclerotic stenosis (n =25).The rabbit models were randomly divided into non-intervention group,celecoxib treatment group (15 mg · kg-1 · d-1,twice daily) and atorvastatin treatment group (5 mg · kg-1 · d-1,once daily) (n=8 each).Four weeks after treatment,the mRNA and protein expressions of COX-2 and mPGES-1 in carotid plaques were determined by RT-PCR and Western blot,respectively.Results The mRNA expressions of COX-2 (0.97±0.09,0.44±0.05,0.60±0.04vs.0.23±0.04,F=66.77,P＜0.01) and mPGES-1 (0.92±0.07,0.41±0.04,0.61±0.03 vs.0.17±0.03,F=54.87,P＜0.01)in carotid atherosclerotic plaques were significantly higher in non intervention group,celecoxib treatment group and atorvastatin treatment group than in normal control group.The mRNA expressions of COX-2 and mPGES-1 were decreased in celecoxib treatment group and atorvastatin treatment group as compared with non-intervention group ( both P ＜ 0.01 ).The protein expressions of COX-2 (0.89±0.06,0.42±0.07,0.62±0.04 vs.0.18±0.05,F=61.75,P ＜0.01) and mPGES-1(0.91±0.05,0.44±0.05,0.63±0.05 vs.0.21±0.04,F=86.44,P＜0.01)in carotid atherosclerotic plaques in non-intervention group,celecoxib treatment group and atorvastatin treatment group were increased as compared with those in normal control group.The mRNA and protein expressions of COX-2 and mPGES-1 were decreased in celecoxib treatment group and atorvastatin treatment group as compared with non-intervention group(all P＜0.01 ).The expressions of COX-2 and mPGES-1 in carotid atherosclerotic plaques were reduced in celecoxib treatment group as compared with atorvastatin treatment group (P ＜ 0.01).Conclusions As COX-2 inhibitor celecoxib,atorvastatin may inhibit the expressions of COX-2 and mPGES-1,and interfere with the inflammatory response which plays key role in the pathological progress of carotid atherosclerotic plaques,and thus slow the progress of carotid atherosclerosis.
