OBJECTIVE:To develop a method for simultaneous determination of 6 alkaloids in Coptis teeta.METHODS:The determination was performed on XtimateTM C18 with mobile phase consisted of 30 mmol/L ammonium bicarbonate [containing 0.1％ triethylamine and 0.7％ ammonia-acetonitrile (gradient elution)] at the flow rate of 1.0 mL/min.The detection wavelength was set at 270 nm,the column temperature was 30 ℃,and the sample size was 10 μL.RESULTS:The linear ranges of jateorrhizine,columbamine,epiberberine,coptisine,palmatine hydrochloride and berberine hydrochloride were 0.85-16.96 mg/L (r=0.999 9),1.25-24.96 mg/L(r=0.999 8),2.05-40.96 mg/L(r=0.999 9),3.65-72.96 mg/L(r=0.999 9),2.88-57.60 mg/L(r=0.999 9) and 13.25-264.96 mg/L(r=0.999 9),respectively.RSDs of precision,stability and reproducibility tests were all lower than 3.0％.Recoveries were 97.14％-102.14％ (RSD=1.93％,n=6),97.00％-102.00％ (RSD=2.06％,n=6),98.18％-101.82 ％ (RSD=1.79％,n=6),96.15％-101.28％ (RSD=2.06％,n=6),96.88％-101.88％ (RSD=1.87％,n=6),99.31％-103.76％ (RSD=1.89％,n=6),respectively.CONCLUSIONS:The method is simple,accurate,stability and reproducible,and can be used for simultaneous determination of 6 alkaloids in Coptis teeta.

Objective: To observe the clinical efficacy of sinew-bone balancing manipulation in treating lumbar disc herniation (LDH) and offer clinical evidence to support the concept of paying equal attention to sinew and bone. Methods: Sixty LDH patients were randomized into an observation group and a control group, with 30 cases in each group. The observation group was treated with the sinew-bone balancing manipulation, and the control group received conventional Tuina (Chinese therapeutic massage) manipulation. The clinical efficacy and posterior muscle chain tone effect were compared between the two groups by observing the visual analog scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and posture-associated indicators. Results: The total effective rate was 86.7％ in the observation group, higher than 76.7％ in the control group, but the between-group difference in efficacy was statistically insignificant (P>0.05). After treatment, the VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry showed significant changes in both groups (P<0.05). The VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry in the observation group were significantly different from those in the control group after treatment (P<0.05), but the between-group difference in the general posture symmetry was statistically insignificant (P>0.05). Conclusion: Both the sinew-bone balancing and conventional Tuina manipulations can reduce pain in LDH patients, improve lumbar function, and adjust the angle-dependent muscle tone coefficient of the posterior muscle chain and lumbar posture symmetry; except for the general posture symmetry of the posterior muscle chain, the sinew-bone balancing manipulation wins out over the conventional Tuina manipulation.

AIMTo observe the effect of quercetin (Que) on the adhesion of platelets to cultured endothelial cells and adhesion molecule expression by human umbilical vein endothelial cells (HUVEC) and platelets.

METHODS[3H]-Adenine labeled platelets were incubated with HUVEC to investigate the effect of Que on adhesion of platelets to HUVEC. The number of platelets adhering to the HUVEC monolayer was determined by liquid scintillation spectroscopy. TNF-alpha induced HUVEC expression ICAM-1 and thrombin induced platelets expression of P-selectin were measured by flow cytometry.

RESULTSQue (0.3-2.4 mumol.L-1) was shown to inhibit the increase of P-selectin expression of thrombin activated platelets. Pretreatment of HUVEC with tumor necrosis factor (TNF-alpha) significantly increased platelets adhesion to HUVEC and the expression ICAM-1. Que (0.6-2.4 mumol.L-1) inhibited this effect of TNF-alpha in a concentration-dependent manner.

CONCLUSIONQue can inhibit the adhesion of platelets to HUVEC and the expression of adhesion molecules (P-selectin and ICAM-1).

BACKGROUNDThe American Heart Association/American Stroke Association proposed a metric called Life's Simple 7 (LS7) to define cardiovascular health (CVH). The presence of a large number of ideal components of CVH is associated with lower cardiovascular disease and all-cause mortality. We aimed to assess CVH using LS7 in a Chinese population undergoing primary and secondary stroke prevention.

METHODSPatients with either ischemic stroke or cardiovascular risk factors were enrolled in the study from October 2010 to July 2013. LS7 components were scored as poor (0 points), intermediate (1 point), or ideal (2 points). The overall LS7 score was categorized as inadequate (0-4), average (5-9), or optimal (10-14) CVH. The Chi-square test, Mann-Whitney U-test, and Kruskal-Wallis test were used.

RESULTSIn total, 706 patients were enrolled. (1) The distribution of the overall LS7 score (n = 255) indicated that 9.4%, 82.4%, and 8.2% of the patients had inadequate, average, and optimal CVH, respectively. The proportion of patients with optimal CVH undergoing secondary stroke prevention was lower than that for patients undergoing primary stroke prevention (3.8% vs. 12.8%, P = 0.005). The vast majority of participants (76.1%) presented with ≤2 ideal health components. (2) The proportions of patients with poor, intermediate, and ideal status, respectively, for the following LS7 components were assessed : t0 otal cholesterol (n = 275; 5.1%, 73.8%, and 21.1%), blood pressure (n = 351; 32.5%, 59.0%, and 8.5%), blood glucose (n = 280; 9.3%, 39.6%, and 51.1%), physical activity (n = 540; 90.7%, 8.7%, and 0.6%), diet (n = 524; 0.2%, 92.4%, and 7.4%), smoking (n = 619; 20.7%, 2.9%, and 76.4%), and body mass index (n = 259; 6.6%, 35.5%, and 57.9%).

CONCLUSIONSFew Chinese patients undergoing stroke prevention had optimal CVH (determined using LS7). Additionally, fewer patients undergoing secondary prevention had optimal CVH than those undergoing primary prevention. In particular, physical activity and diet status in this population require improvement.

OBJECTIVETo describe the daily consumption of plain water and beverages of primary and middle school students in four cities of China.

METHODSA total of 5914 students from Beijing, Shanghai, Guangzhou and Chengdu were selected using multiple-stage random sampling method, and 5868 students completed the study from September to October 2011. The information on amounts and types of drinking water was recorded using a 24 hour measurement for seven consecutive days. The amount of plain water and beverages was analyzed for subjects in different gender, grades and cities.

RESULTSThe daily consumption of plain water of subjects was (744 ± 484) ml (68.3% of total drinking water) with statistically significant difference among the Guangzhou, Beijing, Shanghai and Chengdu ((869 ± 528), (818 ± 518), (702 ± 471), and (573 ± 333) ml; F = 113.74, P < 0.05). The amount of plain water in boys (809 ± 534) ml was significantly higher than in girls (683 ± 436) ml (Z = 9.58, P < 0.05) while higher in urban (792 ± 531) ml than in rural (695 ± 427) ml (Z = -6.09, P < 0.05). The consumption of plain water in high school students was the highest (829 ± 513) ml, and that in primary students was the lowest (672 ± 426) ml (F = 55.23, P < 0.05). The average daily consumption of beverages was (345 ± 287) ml (31.7% of total drinking water) and the highest in Shanghai (424 ± 304) ml, then in Beijing (347 ± 303) ml and in Guangzhou (316 ± 267) ml, the lowest in Chengdu (293 ± 255) ml (F = 58.94, P < 0.05). The consumption of beverages for students in urban areas (394 ± 301) ml was higher than that in rural areas (296 ± 264) ml (Z = -14.48, P < 0.05), but no significant difference between boys (348 ± 306) ml and girls (342 ± 269) ml (Z = -1.44, P > 0.05). The consumption of beverages of high school students (356 ± 309) ml and middle school students (360 ± 301) ml were higher than primary school students (328 ± 263) ml (F = 8.37, P < 0.05).

CONCLUSIONThe major drinking water of primary and middle school students in four cities of China was plain water. The amounts of consumption of plain water and beverages varied in different cities, urban and rural and levels of education.

OBJECTIVETo investigate the effect of apelin on vasodilatation of isolated pulmonary arterial rings in rats and its relationship to the nitric oxide (NO) pathway, and to observe the difference of vasodilatation between hypoxic rats and normoxic rats.

METHODSThirty-six male Sprague-Dawley (SD) rats were randomly divided into hypoxic group and normoxic group. The effects of accumulated apelin on pulmonary arterial rings preconstricted with norepinephrine (NE) were observed by using tissue organ bath system. After pulmonary arterial rings were pretreated with three methods: removing the endothelium, pretreating with nitric oxide synthase inhibitor L-NAME or soluble guanylatecyclase inhibitor ODQ, the different effect of apelin was observed. In addition, the difference of vasodilatation between hypoxic rats and normal rats were observed.

RESULTS(1) Exposure of intact endothelium pulmonary arterial rings preconstricted by NE to apelin at concentration (0.01 - 100 nmol/L) induced a significant concentration dependent relaxation. The maximal vasorelaxant effect of apelin was 10.62% +/- 2.60%, which was inhibited by removal of the endothelium (P < 0.01), pretreatment with L-NAME (P < 0.01) or ODQ (P < 0.01). (2) Response of pulmonary arterial rings from hypoxic pulmonary hypertension rats was decreased (P < 0.05). Compared to normal rats, at a concentration of 100 nmol/L, the response to apelin on arteries from hypoxic rats decreased 60.45% (P < 0.01). But the values of EC50 were not significantly different (P > 0.05).

CONCLUSIONThese results indicate that apelin relaxes the pulmonary arterial rings of rats in an endothelium dependent manner, which may have a relationship to NO signaling pathway. The response of vasodilatation is decreased in the pulmonary arterial rings from the hypoxic rats.

PURPOSE: To demonstrate the feasibility, safety, and technical strategies of hand-assisted laparoscopic complete mesocolic excision (HAL-CME) and to compare oncological outcomes between HAL-CME and the open approach (O-CME) for right colon cancers. METHODS: Patients who were scheduled to undergo a right hemicolectomy were divided into HAL-CME and O-CME groups. Measured outcomes included demographic variables, perioperative parameters, and follow-up data. Demographic variables included age, sex distribution, body mass index (BMI), American Society of Anesthesiologists (ASA) physical status classification, previous abdominal surgery, tumor localization, and potential comorbidities. Perioperative parameters included incision length, operative time, blood loss, conversion rate, postoperative pain score, postoperative first passage of flatus, duration of hospital stay, total cost, number of lymph nodes retrieved, TNM classification, and postoperative complications. Follow-up data included follow-up time, use of chemotherapy, local recurrence rate, distant metastasis rate, and short-term survival rate. RESULTS: In total, 150 patients (HAL-CME, 78; O-CME, 72) were included. The groups were similar in age, sex distribution, BMI, ASA classification, history of previous abdominal surgeries, tumor localization, and potential comorbidities. Patients in the HAL-CME group had shorter incision lengths, longer operative times, less operative blood loss, lower pain scores, earlier first passage of flatus, shorter hospital stay, higher total costs, similar numbers of lymph nodes retrieved, similar TNM classifications, and a comparable incidence of postoperative complications. The 2 groups were also similar in local recurrence rate, distant metastasis rate, and short-term survival rate. CONCLUSION: The results demonstrate that the HAL-CME procedure is a safe, valid, and feasible surgical method for right hemicolon cancers.

Objective: To observe the blood perfusion volume variation pattern in the body surface microcirculation at the Yuan-Primary and the Xi-Cleft points during the menstrual cycle in female college students with moderate constitution under normal physiological state of the uterus; to explore the specific laws of the body surface microcirculation at the Yuan-Primary and Xi-Cleft points in response to the uterine qi and blood changes under normal physiological conditions, and to provide the experimental basis for the specificity of acupoints reflecting the uterine function. Methods: Forty-three healthy and moderate constitution female college students with regular menstrual cycles, without dysmenorrhea and not yet giving birth were recruited. Bilateral Yuan-Primary points [Taichong (LR 3), Taibai (SP 3) and Taixi (KI 3)] and Xi-Cleft points [Zhongdu (LR 6), Diji (SP 8) and Shuiquan (KI 5)], belonging to the three yin meridians of foot and adjacent to the spinal cord segment of the uterus, were selected as the detection acupoints; the crossing point of the three yin meridians of foot [Sanyinjiao (SP 6)], the uterus-related meridian acupoint [Xuehai (SP 10)], the uterus-non-related meridian acupoint [Xuanzhong (GB 39)], and the non-meridian non-acupoint point were selected as the control points. The laser speckle blood flow imaging technique was used to monitor the blood perfusion volume in skin microcirculation at the above points at the menstrual, follicular, ovulatory, and luteal phases of the subjects. Results: The blood perfusion volume in the body surface microcirculation at the right Zhongdu (LR 6) at the ovulatory phase was higher than that at the menstrual, follicular and luteal phases (all P<0.05); there was no significant difference in the microcirculation blood perfusion volume at the other points among different phases (all P>0.05). Conclusion: The blood perfusion volume in the body surface microcirculation at Zhongdu (LR 6), the Xi-Cleft point of the Liver Meridian, shows a specific response to qi and blood changes in the uterus of women with moderate constitution.
