OBJECTIVETo explore the clinical efficacy and mechanism of acupuncture and tapping therapy in the treatment of type 2 diabetes of yin deficiency pattern combined with stasis in the patients.

METHODSOne hundred and twelve patients were treated with acupuncture, followed by tapping method. The reinforcing method with lifting, thrusting and rotating needle technique was used at Taixi (KI 3), Shenmen (HT 7), Taibai (SP 3), Taiyuan (LU 9), Sanyinjiao (SP 6) and Zusanli (ST 36); and the even-needling technique was used at Taichong (LR 3), Hegu (LI 4), Xuehai (SP 10) and Fenglong (ST 40). The needles were remained for 30 min. After needle removal, the tapping method with plum-blossom needle was applied to Geshu (BL 17), Yishu (EX-B 3), Ganshu (BL 18), Shenshu (BL 23) and Pishu (BL 20), once every two days. The treatment of 3 months was required. The changes were observed before and after treatment in the relevant indices of fat-islet axis such as fasting plasma glucose (FPG), fasting leptin (FLP), fasting insulin (FINS), insulin sensitivity index (ISI), insulin resistance (Homa IR), insulin secretion index (Homa-beta) and the indices of obesity and blood lipids in the patients.

RESULTSAfter treatment, the total effective rate was 84.8% (95/112), in which the efficacy on the stasis predominated syndrome was better than that of yin deficiency predominated syndrome [92.9% (52/56) vs 76.8% (43/56), P < 0.05]. Before treatment, FPG, FLP, FINS, Homa-IR, total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), body mass, body mass index (BMI), fat percentage (F%) and obesity degree in the patients were higher obviously than those in the normal group (all P < 0.01); high-density lipoprotein cholesterol (HDL-C) and ISI were lower than those in the normal group (both P < 0.01). After treatment, FPG, FLP, FINS, Homa-IR, TC, TG, LDL-C, body mass, BMI, F% and obesity degree were all reduced obviously as compared with those before treatment (all P < 0.01). ISI and HDL-C were increased apparently (both P < 0.01). The efficacy on mild obesity was superior to that on moderate and severe obesity, and the efficacy in the young patients was better than that in the elderly, the efficacy in the males was better than that in the females, but the differences were not significant (all P > 0.05). The efficacy in the cases with 10 years duration of sickness was superior to those with over 10 years duration of sickness (P < 0. 01).

CONCLUSIONAcupuncture and tapping therapy achieves the significant efficacy on type 2 diabetes of yin deficiency pattern combined with stasis and its effect mechanism is related to the positive regulation of glucose, lipid metabolism and fat-islet axis.

Objective To study the clinicopathologieal features and expression of cyclin D1 and p53 in epithelial ovarian tumors,and to investigate the correlation between pathogenesis of ovarian cancer and epithelial borderline tumors.Methods Fifty four cases of ovarian borderline tumors and 45 cases of ovarian carcinomas from the People's Hospital,Peking University were reviewed retrospectively.The clinical data and pathological findings were analyzed.Immunohistochemical study of cyclin D1 and p53 was performed in all 99 cases.Results(1)In borderline tumors,the age of patients ranged from 14-82 (mean age=42.5)years.International Federation of Gynecology and Obstetrics(FIGO)stage of borderline tumors was stage Ⅰ in 48 cases,stage Ⅱ in 3 cases,and stage Ⅲ in 3 cases.In ovarian carcinomas,the age of patients ranged from 26-80(mean age=53.5)years.FIGO stage of carcinoma was stage Ⅰ in 6 cases, stage Ⅱ in 8 cases,stage Ⅲ in 26 cases,and stage Ⅳ in 5 cases.In follow-up of 54 cases with borderline tumors the 5-year survival rate was 98% and of 45 cases with carcinomas a 5-year survival rate of 51% was noted.(2)In 54 cases of borderline tumors,mucinous types accounted for 56%(30/54)and serous types accounted for 30%(16/54).There were 5 cases with micropapillary pattern,3 cases with peritoneal implants,3 cases with lymph node involvement,6 cases with microinvasion,one case with intraepithelial carcinoma,and one case with mural nodules.In 45 cases of carcinomas,serous carcinoma was the most (49%,22/45).The remainder included 3 cases of mucinous types,8 cases of endometrioid types,6 cases of transitional cell types,3 cases of mixed phenotype and 3 cases of undifferentiated types.(3) Overexpression of cyclin D1 and p53 was observed in 31%(14/45)and 56%(25/45)of ovarian carcinomas, respectively.There was a significant association between p53 overexpression and tumor grade.In the borderline tumor group,69%(37/54)had overexpression of cyelin D1 and 6%(3/54)had overexpression of p53.There were significant differences in expression of cyclin D1 and p53 between conventional serous borderline tumors and high-grade serous carcinomas(cyclin D1:91% vs 26%;p53:0 vs 58%).However, micropapillary serous borderline tumors and low-grade serous carcinomas showed remarkably similar expression of cyelin D1 and p53.Conclusions Epithelial ovarian borderline tumors are distinct from ovarian cancer in clinical progress and prognosis,and histological types.Overexpression of cyclin D1 is common in ovarian borderline tumors and low grade carcinomas.And overexpression of p53 is more common in high grade ovarian carcinomas.Conventional serous borderline tumors are distinct from high-grade serous carcinomas in pathogenesis.Micropapillary serous borderline ovarian tumors may be closely related to low grade serous carcinomas.

OBJECTIVETo observe the histocompatibility of a polypropylene matrix implanted subcutaneously for potential hair follicle transplantation in rabbits.

METHODSThe polypropylene matrix for harboring the hair follicles was prepared and implanted subcutaneously at the neck of 5 New Zealand white rabbits by means of hair follicle unit transplantation. At 1 week after the transplantation and then on a monthly basis in the following 6 months, full-thickness skin tissues were sampled at the site of grafting to evaluate the histocompatibility of the matrix material using HE staining and scanning electron microscopy.

RESULTSAt 1 week after implantation of the matrix material, a small number of inflammatory cells and lymphocytic infiltration were observed around the graft, with mild hyperemia in the proliferative capillaries and mild inflammatory responses. In the following 6 months, the inflammatory cells and lymphocytes around the graft decreased obviously or even disappeared, and such graft rejection responses as tissue lysis and necrosis were not observed. A large quantity of collagen fibers were found to encapsulate the polypropylene material.

CONCLUSIONPolypropylene matrix graft has good histocompatibility with the rabbit subcutaneous tissue without producing obvious graft rejection responses, suggesting its feasibility for further experiments of hair follicle transplantation.

OBJECTIVETo observe the effect of obesity on pharmacokinetics and pharmacodynamics of isoflurane.

METHODSTwenty-six patients undergoing cholecystectomy were divided into obese group (Group A, BMI > or = 27, n = 13) and normal body weight group (Group N, BMI < or = 24, n = 13) according to body mass index (BMI). All patients were given to the same isoflurane anesthesia. Inspired and end-expired concentrations of isoflurane were monitored and uptake fraction of isoflurane were calculated.

RESULTSIsoflurane concentrations of vaporizer in Group A [(1.8 +/- 0.3)%] were evidently higher than those in Group N [(1.5 +/- 0.1)%] at all observed points (P < 0.05 or P < 0.01). Uptake fraction of isoflurane in Group A were higher than those in Group N at observed points (P < 0.05, P < 0.01 or P < 0.001), but there were no differences in the time when isoflurane concentration was lowered to 50% and awake time between the two groups after discontinuing inhaling isoflurane.

CONCLUSIONSObese patients demand higher inspired concentration and uptake of isoflurane than those in normal weight patients but discharge of isoflurane was influenced by obesity within the observed period of (66 +/- 33) min.

OBJECTIVETo investigate the protective effect and mechanism of Shenqi Compound on diabetic angiopathy modeled rats.

METHODSTotally 18 SD rats were randomized into 3 groups, i.e., the normal control group, the diabetic mellitus (DM) group, and Shenqi Compound group, 6 in each group. The DM rat model was established by feeding high-fat diet (to induce hyperlipidemia) +intraperitoneal injection of small dose streptozotocin (STZ). Shenqi Compound was given to rats in the Shenqi Compound group at the daily dose of 2 g/kg. Equal volume of normal saline was given to rats in the model group and the normal control group by gastrogavage. All treatment was lasted for 12 weeks. Then 2-D and ultrasonic integrated backscatter technique were used to evaluate structural and functional changes of abdominal aorta in the progression of diabetic macroangiopathy. The fibrosis degree of the aorta vessel and myocardium capillaries were observed by using HE and Masson trichrome staining. The tension of the aortic vascular ring was determined. The transforming growth factor beta (TGF-beta) mRNA expression was detected by real time PCR (RT-PCR). The protein expression of TGF-beta, collagen I, collagen III, connective tissue growth factor (CTGF), and phosphorylation P38 MAPK were detected by Western blot.

RESULTSCompared with the normal control group, abdominal aortic systolic inner diameter, diastolic inner diameter, Peterson elastic modulus, stiffness index, and backscatter integral significantly increased; the rangeability of integral backscatter and the extension coefficient of cross section significantly decreased in the DM group (all P < 0.05). After 12 weeks aforesaid indices were obviously improved in the Shenqi Compound group (P < 0.05). Results of HE and Masson staining showed that the fibrosis degree of the aorta vessel and myocardium capillaries was obviously alleviated in rats of the Shenqi Compound group (P < 0.05). Results of the aortic vascular ring tension showed that acetylcholine induced vasodilatation and maximum diastolic percent were obviously elevated in the Shenqi Compound group (P < 0.05). Compared with the normal control group, the mRNA expression of TGF-beta, and the protein expression of TGF-beta, collagen I, and collagen III, and phosphorylation of P38 MAPK all significantly increased in the DM group (P < 0.05). Compared with the DM group, the mRNA expression of TGF-beta, and the protein expression of TGF-beta, collagen I, and collagen III, and phosphorylation of P38 MAPK all decreased (P < 0.05).

CONCLUSIONSShenqi Compound could effectively improve the arterial function in diabetic marcoangiopathy and microvascular dysfunction. The mechanism might be due to the down-regulating the expression of TGF-beta, and further suppressing the phosphorylation of P38 MAPK, reducing the synthesis of collagen I and collagen III, therefore, ameliorating arterial and myocardial interstitial fibrosis.

Objective To study effects of fluid resuscitation on thoracoabdominal injury combined with hemorrhagic traumatic shock.Method A total of 98 patients,who were treated in Affiliated Zhongshan Hospital of Dalian University from November 2004 to December 2006,were retrospectively analyzed.The patients were diagnozed according to Surgery(fifth edition).Patients were divided into delayed fluid resuscitation group(n= 51)and immediate fluid resuscitation group(n=47).Patients in delayed fluid resuscitation group were given with balanced salt solution for the body to maintain basic requirements.Patients in immediate fluid resuscitation group were rapidly administered with a lot of isotonic crystaUoid and(or)colloid solution after admission. Hemoglobin,platelet count,hematocrit,blood lactic acid,basedeficit,preoperative resuscitation time and mortality were compared between the two groups.Paired t test and variance analysis or x~2 test were used.Results The transfusion fluid volume of delayed group and immediate group was(1586?346)ml,(3520?575)ml, respectively,with P value

Objective To explore the association between estimated glomerular filtration rate (eGFR) and metabolic syndrome (MS) . Method The data were from the China Health and Nutrition Survey (CHNS) . The data included the physical measurement and biochemical markers of adults of CHNS in 2009. Finally, 7309 individual observations were included in the analysis. Results According to the criteria of MS, 2034 patients were diagnosed as MS, and the prevalence was 27.83%. There were 1508 (74.14%) patients had moderate reduced eGFR in MS patients, and 3357 individuals (63.64%) were diagnosed as moderate reduced eGFR in non-MS patients. There was significant difference between two groups (X2=72.13, P<0.001) . The incident of moderate reduced eGFR was positively associated with fasting plasma glucose (OR=1.22, 95%CI: 1.06-1.42, P=0.005), triglyceride (OR=1.21, 95%CI: 1.05-1.38, P=0.005) and negatively associated with HDL-C (OR=1.23, 95% CI: 1.06-1.41, P=0.004) . Conclusion The MS and its components might be the influencing factors of developing moderate reduced eGFR, and the screening should be focused on the population with MS.

OBJECTIVETo set up a platform for phenotype-based primary screening of drug candidates promoting neuronal subtype differentiation in embryonic stem cells (ES) with light microscope.

METHODSHanging drop culture 4-/4+ method was employed to harvest the cells around embryoid body (EB) at differentiation endpoint. Morphological evaluation for neuron-like cells was performed with light microscope. Axons for more than three times of the length of the cell body were considered as neuron-like cells. The compound(s) that promote neuron-like cells was further evaluated. Icariin (ICA, 10(-6)mol/L) and Isobavachin (IBA, 10(-7)mol/L) were selected to screen the differentiation-promoting activity on ES cells. Immunofluorescence staining with specific antibodies (ChAT, GABA) was used to evaluate the neuron subtypes.

RESULTSThe cells treated with IBA showed neuron-like phenotype, but the cells treated with ICA did not exhibit the morphological changes. ES cells treated with IBA was further confirmed to be cholinergic and GABAergic neurons.

CONCLUSIONPhenotypic screening with light microscope for molecules promoting neuronal differentiation is an effective method with advantages of less labor and material consuming and time saving, and false-positive results derived from immunofluorescence can be avoided. The method confirms that IBA is able to facilitate ES cells differentiating into neuronal cells, including cholinergic neurons and GABAergic neurons.
