The main acupoints ofZhongwan (CV 12), Tianshu (ST 25), Zusanli (ST 36), Shangjuxu (ST 37), Dachangshu (BL 25) and Shenque (CV 8), in combination with the corresponding acupoints based on the syndrome differentiation, were selected to treat 28 cases of chronic nonspecific ulcerative colitis, the result showed clinical cure in 18 cases, clinical effect in 15 cases, failure in 5 cases. The most treatment times were 46, and the least 25.

AIM: The purpose of this study was to determine whether the signal transduction systems were activated at the molecular atrial tissue level in patients with atrial fibrillation (AF) and whether atrial expression of extracellular-signal regulated kinase (ERK) and protein phosphatases is altered. METHODS: Atrial tissue sample of 30 patients undergoing cardiac surgery were examined. 20 patients had AF, 10 patients had no history of AF. The mRNA expression of calcineurin B and MKP-1 were detected by semi-quantitative RT-PCR. ERK1 and phospho-ERK1 were analyzed at the protein level by Western blot. RESULTS: Western blot analysis showed that atrial fibrillation did not induce significant change in ERK1 expression level in the left atrium. In contrast , phospho-ERK1 content was increased in the patients with AF in comparison with those who had sinus rhythm (SR). The mRNA expression of calcineurin B and MKP-1 in the patients with AF were significantly higher than that in patients with SR. CONCLUSION: The activation of extracellular-signal regulated kinase and protein phosphatases may have correlation with the initiation or maintenance of atrial fibrillation.

BACKGROUND:There are many reports about clinical effect of femoral fractures with intramedul ary nail and distal femoral fractures with locking plate. However, there is less report about clinical effect of femoral and distal femoral fractures.
OBJECTIVE:To investigate the clinical effect of femoral and distal femoral fractures using intramedul ary nail combined with locking plate.
METHODEighteen patients with femoral and distal femoral fractures were treated by internal fixation with intramedul ary nail combined with locking plate. Among them, six cases had femoral and supracondylar fractures, seven cases had femoral and condylar fractures, and five cases had femoral and intercondylar fractures.
According to the AO classification, three cases were type 33A2, three cases were type 33A3, two cases were type 33B1, five cases were type 33B2, one case was type 33C1, three cases were type 33C2, and one case was type 33C3. The fractures union and complications were fol owed up and observed, and knee joint function was judged by HSS score.
RESULTS AND CONCLUSION:Al the 18 patients were fol owed up for 12-24 months. The time for fracture union ranged from 3 to 5 months, average 3.4 months. No infection and disunion, no fracture malunion, no internal fixation loosening and breaking, no refracture happened. The HSS score ranged from 68 to 96 points, average 86.8 points. There were 12 excellent cases, 5 good cases, and 1 common case. The excellent and good rate was 94.4%. The internal fixation using intramedul ary nail combined with locking plate is a good method for treatment of femoral and distal femoral fractures, due to less surgical trauma, simple and reliable fixation, high rate of fracture healing, low rate of complications, and excellent function.

[Objective]To compare the clinical outcomes of fresh embryo transfer of the in vitro fertilization/intracytoplasmic sperm injection and embryo transfer(IVF/ICSI-ET)in different age groups as well as in different responders using gonadotropin-re-leasing hormone agonist(GnRH-a)long protocol or GnRH antagonist(GnRH-ant)protocol.[Methods]A retrospective analysis was performed on 737 IVF/ICSI cycles,including 386 cycles of GnRH-a long protocol(group A)and 351 cycles of GnRH-ant protocol (group B),from August 28,2015 to December 31,2016. Then all the cycles were divided into sub-groups by ages and retrieved oo-cyte numbers:group a1(<38 years),group a2(≥38 years);group b1(n≤5),group b2(6≤n≤15),group b3(n>15). The basic information of patients and clinical outcomes were compared.[Results](1)Comparable results were obtained from group A and group B in these following variables such as fertilization rate,normal fertilization rate,biochemical pregnancy rate and miscarriage rage. But the stimulation period,the total gonadotropin(Gn)dosage,estradiol(E2)level and endometrial thickness on the day of human chorionic gonadotropin(hCG)administration,number of oocytes retrieved and mature oocytes,ovarian hyperstimulation syn-drome(OHSS)rate,implantation rate and clinical pregnancy rate were significantly higher in group A than group B(P<0.05),and significantly higher cancellation rate of fresh embryo transfer was observed in group B(P<0.001).(2)When divided by ages,no mat-ter in sub-group a1 or sub-group a2,the implantation rate was slightly lower in GnRH-ant protocol than in GnRH-a long protocol, although they failed to reach significant difference(sub-group a1:32.6%vs 39.8%,P=0.067;sub-group a2:9.7%vs 17.9%,P=0.066). The clinical pregnancy rate was comparable using these two protocols in sub-group a1(54.8%vs 50.4%,P=0.429),but it was significantly lower by using GnRH-ant protocol than GnRH-a long protocol in sub-group a2(19.6%vs 39.1%,P=0.021).(3) When divided by numbers of oocytes retrieved,the implantation rate was significantly lower when using GnRH-ant protocol in sub-group b1(13.1%vs 26.0%,P=0.026),but we failed to observe significant differences in other two sub-groups. The clinical preg-nancy rates were comparable in all sub-groups ,whereas differed considerably in sub-group b1 (36.6% vs 19.3%,P = 0.056).[Conclusion]Overall,the implantation rate and clinical pregnancy rate were higher in GnRH-a long protocol than those in GnRH-ant protocol. Nevertheless,GnRH-ant protocol could reduce the dosage of Gn,shorten the treatment duration,and effectively reduce the occurrence of OHSS. There were similar pregnancy outcomes in two protocols for normal responders and high responders ,while for advanced patients or other poor responders,the implantation rate and clinical pregnancy rate were higher in GnRH-a protocol.

Objective Analyzing risk factors for gastrointestinal bleeding(GIB) after coronary artery bypass grafting(CABG). Methods 582 cases undergoing CABG from August 2001 to May 2005 were divided into two groups (GIB group ,n=6 ;control group,n=576) . Preoperative , operative and postoperative clinic data were com-pared. Results The ratio of over-aging(age greater than 70), hypertension, cerebrovascular disease, myocardial in-fraction,heart function (NYHA) over Ⅲ and postoperative low output syndrome (LOS) in GIB group were signifi-cantly higher than that in control group;age, blood transfusion and hospitalized time were significantly higher and left ventricular ejective fraction was significantly lower in GIB group than that in control group. Age over 70,history of myocardial infraction and heart function (NYHA) over Ⅲ were selected as risk factors of GIB after CABG by step-wise logistic regression analysis. Conclusions It is very useful for precaution, early diagnosis and early therapy of GIB after CABG to evaluate if patients have the risk factors of GIB after CABG before operations.

The levels of low-density lipoprotein(LDL)glycation from control group,diabetic HbA1C < 7.0%,and HbA1C>7.0% groups were(17.7±2.31),(34.29±5.73),and(48.79±7.82)Glycogroups/LDL by fluorimetry.The LDL binding to its receptor in three groups were(37.65±5.20),(27.36±4.34),and(15.07± 2.23)ng/mg cell protein measured by enzyme-linked immunoreceptor assay.The glycated levels in two diabetic groups were higher than that in control group,and higher in HbA1C>7.0% group than in HbA1C<7.0% group(all P< 0.01).The results of LDL binding capacity to its receptor were just the opposite.

Objective To evaluate the diagnostic and therapeutic role in bladder pain syndrome/interstitial cystitis (BPS/IC) of random bladder biopsy and hydrodistention with cystoscopy under anesthesia.Methods A retrospective review of cases in our BPS/IC center was performed from 2005 to 2010. One hundred and nineteen patients were included who are diagnosed as the bladder pain syndrome/interstitial cystitis (BPS/IC).There were 32 male patients,aged 47 to 64 years,and 56 years on average; 87 female cases,aged 23 to 67 years,49 years on average.Patients with bladder pain symptoms underwent a thorough evaluation which include voiding diary,pelvic pain、urgency and frequency questionnaire,urine culture,cytology,acid fast bacilli and upper tract imaging.Cystoscopy and random bladder biopsy had been undertaken with general anesthesia.Before and after hydrodistention with cystoscopy,the patients daily frequency of urination,the maximum urine volume,pain scores,symptom scores,QOL score were observed to understand whether there are significant improvement. Results One hundred and nineteen BPS/IC cases underwent random bladder biopsy and hydrodistention with cystoscopy under anesthesia,and finally 102 cases were confirmed of IC; 17 cases were not IC. Eight patients who were previously diagnosed as BPS/IC were found bladder transitional cell carcinoma as the cause of bladder pain symptoms( including 4 cases carcinoma in situ,1 case Low grade non-invasive bladder cancer,3 cases High grade invasive bladder cancers),and 4 of whom had no hematuria. Mean time from the occurrence of BPS to diagnosis of transitional cell carcinoma was 10.8 months. Three patients previously diagnosed as BPS/IC were found tuberculous cystitis as the cause of symptoms,and one eosinophilic cystitis,three chemical cystitis,two radiation cystitis were also detected.Before hydrodistention with cystoscopy under anesthesia,the daily frequency of urination in 102 cases diagnosed for IC patients was 42.1 ±5.6; the maximum urine volume was 141.0 ± 8.3 ml; pain score 7.6 ± 3.0; O'Leary-Sant questionnaire symptom score was 27.7 ± 4.2; QOL score was 7.6 ± 2.4.After hydrodistention with cystoscopy under anesthesia,the daily frequency of urination in 102 IC patients was 23.3 ± 3.4,and the maximum urine volume was 352.0 ± 1.7 ml ; pain score was 3.3 ± 4.3 ; O'Leary-Sant questionnaire symptom score was 12.5 ± 7.3 ; QOL score was 3.2 ± 5.1. Before and after hydrodistention with cystoscope under anesthesia,all of the daily frequency of urination,the maximum urine volume,pain scores,symptom scores,QOL score in 102 IC patients were significant improved (P ＜ 0.05 ). Conclusions BPS/IC remains a diagnosis of exclusion.Random bladder biopsy and hydrodistention with cystoscopy under anesthesia play an important diagnostic and therapeutic role in BPS/IC.

Background Antagonists against vascular endothelial growth factor (VECF) play key roles in treating and preventing neovascular ophthalmopathy. As a novel anti-angiogenic factor, insulin-like growth factor binding protein-related protein 1 (IGFBP-rP1) might be an antagonist against VEGF in eye. Objective This study was to explore the inhibitory effect of IGFBP-rP1, a novel anti-angiogenic factor, on VEGF-induced retinal angiogenesis in vitro. Methods The retina-choroid endothelial cell line ( RF/6A ) was cultured in DMEM containing 10% fetal bovine serum. Culture cells were divided into control group(free-serum culture group) ,10mg/L VEGF culture group and different concentrations of IGFBP-rP1 (50,100,200 mg/L) +10 mg/L VEGF group. The expression of IGFBP-rP1 in the cells was detected by immunofluorescence assay. The proliferation and migration of RF/6A cells were evaluated using MTS colorimetric assay and the chemotactic motility assay, respectively. Flow cytometry was used to detect the apoptosis of RF/6A cells. Results The immunofluorescence assay RF/6A cells showed the green fluorescence in cytoplasm and red fluorescence in nuclei after cells were exposed to any concentration of IGFBP-rP1 ,but only red fluorescence was seen in nuclei in control cells. After stimulation of 10 mg/L VEGF,the proliferation value (A490) was elevated and the numbers of cell migration were increased in comparison with control group (t = -15. 191, P = 0. 000; t = -21. 274, P = 0. 000 ) , but the cellular apoptosis rate was lower than the control group (t - 10. 228, P = 0. 000 ) . After treated with various concentrations of IGFBP-rP +10% VEGF, the proliferation and migration of RF/6A cells were significantly decreased in comparison with only 10% VEGF group (F = 534. 158,P = 0. 000;F = 2742. 323,P = 0.000,respectively) ,and the inhibitory effects were gradually enhanced with the increase of IGFBP-rP1 levels (P<0. 05). The apoptosis rate of RF/6A cells in 50,100 and 200 mg/L + 10 mg/L VEGF groups increased by ( 1. 26±0. 04)% ,( 1. 50±0. 07)% and ( 1. 93±0. 27)% respectively,showing significant differences among different groups ( F = 274. 273, P = 0. 000). Conclusion IGFBP-rP1 inhibits the proliferation and activity of retina and choroid endothelial cells induced by VEGF at a concentration-independent manner. It appears to be as a novel endogenous inhibitory factor in retinal angiogenesis.

KK-Ay mice with type 2 diabetes were divided into metformin plus high-fat diet,metformin plus low-fat diet,high fat diet alone and low fat diet alone groups.AMP-activated protein kinase(AMPK)activity was measured in skeletal muscle.The results showed that metformin and low-fat diet were able to increase AMPK activity.However,no additive effect on AMPK activity by metformin and low-fat diet was found.
