Objective To evaluate the usage situation and the trend of traditional Chinese medicine injection for activating blood circulation in our hospital. Methods The sales amount and drug use frequency (DDDs) and drug utilization index (DUI) of traditional Chinese medicine injection for activating blood circulation were sorted and analyzed in our hospital from the fourth quarter of 2011 to the third quarter of 2012. Results The total sales amount of traditional Chinese medicine injection for activating blood circulation gradually increased in our hospital during that time. The proportion of varieties with the ratio DUI sum/DDDs sort of closed to 1 (0.75≤order ratio≤1.25) in the three quarters of 2012 accounted for 53.33%, 53.33%, and 66.67%, respectively. This indicated that the usage of traditional Chinese medicine injection for activating blood circulation was more unreasonable, but tended to be reasonable. Conclusion The usage of traditional Chinese medicine injection for activating blood circulation was basically rational in our hospital, and efficacy of clinical pharmacist intervention was obvious. Effective and safe evaluation of traditional Chinese medicine injection can be further strengthened, in order to improve the efficacy and reduce the adverse reaction.

BACKGROUND: Many basic researches and clinical observations prove that compound preparation of gingko extract and dipyridamole has an obvious effect on microcirculation. Methycobal is commonly used to repair nerve on clinic. Combination of compound preparation and methycobal has a great effect on treating diabetic peripheral neuropathy (DPN).OBJECTIVE: To observe the improved effect of combination of compound preparation and methycobal on conduction velocity of common peroneal nerve and hemorheology of DPN patients.DESIGN: Randomized controlled design and validated experiment on the basis of patients.SETTING: Department of Comprehensive Medicine, Tongji Hospital of Tongji Medic.al College, Huazhong University of Science and Technology.PARTICIPANTS: A total of 120 patients with type 2 diabetes mellitus (DM) combined with DPN were selected from the Department of Comprehensive Medicine in Tongji Hospital of Tongji Medical College affiliated to Huazhong University of Science and Technology between January 2002 and January 2005. Subjects were randomly divided into treatment group and control group with 60 in each group. All cases were consent.METHODS: Cases in the treatment group were venously dripped with 25 mL compound preparation and 250 mL saline (Guizhou Yibai Pharmacology Company Limited) once a day; meanwhile, 500 μg methycobal (Eisai Community, Japan) was intramuscularly injected into cases once a day for 4 successive weeks. Cases in the control group were intramuscularly injected with 500 μg methycobal once a day for 4 weeks.MAIN OUTCOME MEASURES: Conduction velocity of peroneal nerve and hemorheological indexes (blood viscosity, hematocrit and aggregative rate of platelet) of patients in the two groups at 1 day before treatment and at 4 weeks after treatment.RESULTS: A total of 120 patients were involved in the final analysis. ① Conduction velocity of motor nerve was faster in treatment group after treatment than that before treatment and that in control group after treatment [(45.6±4.3), (38.5±3.8), (41.4±6.2) m/s, t=9.585, 4.312, P ＜ 0.01]; conduction velocity of sensory nerve was faster in treatment group after treatment than that before treatment and that in control group after treatment [(45.8±4.2), (36.7±4.8), (38.2±4.9) m/s, t=11.047, 9.120, P ＜ 0.01]. ② Values of high-shearing blood viscosity, low-shearing blood viscosity and plasma viscosity were lower in treatment group after treatment than those before treatment and those in control group after treatment (P ＜ 0.01). ③Value of hematocrit was lower in treatment group after treatment than those before treatment and those in control group after treatment [(41.32 ±3.56)%,(46.32±3.43)%, (44.32±4.49)%, t=7.834,4.05, P ＜ 0.01]. ④ Aggregative rate of platelet was lower in treatment group after treatment than those before treatment and those in control group after treatment [(31.35±2.11)%,(48.44±2.68)%, (45.91±3.54)%, t=38.810, 27.367, P ＜ 0.01].CONCLUSION: Combination ofcompound preparation and methycobal can increase nerve conduction velocity and decrease blood viscosity and aggregative rate of platelet, and it is also an effective method for treating DPN.

BACKGROUND: Resistin is an adipocyte-derived polypeptides. While central obesity can result in insulin resistance and type 2 diabetes mellitus.OBJECTIVE: To compare the expression of resistin protein in subcutaneous adipose tissue of normal human abdominal and thigh, and to investigate the role of resistin in central obesity bringing insulin resistance.DESIGN: Controlled observational experiment.SETTING: Department of Endocrinology, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.PARTICIPANTS: Totally 20 patients hospitalized between January and April 2003 at the Department of Surgery of Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology were selected. All cases were divided into abdominal fat group with 12 cases and thigh fat group with 8 cases based on the site of fat tissue.METHODS: ①Blood pressure, height, body mass were measured and body mass index (BMI), percentage of body fat (BF%) in vivo (according to formulas induced by data from white people) were calculated: Male=1.2×body mass (kg)+height-2 (M-2)+0.23×age-16.2; Female =1.2× body mass (kg)×height-2 (m-2)+0.23×age-5.4. ②Fasting blood glucose was measured with glucose oxidase assay. ③Protein was isolated with lysis buffer and protein concentration was identified with Bradford method; The expression of resistin protein was measured with Western-blot method.MAIN OUTCOME MEASURES: Blood pressure, BMI, BF%; fasting blood glucose and expression of resistin protein of all cases of the two groups.RESULTS: Totally 20 patients were involved the result analysis. ①There were no significant difference in fast blood glucose, systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI) and BF%between two groups (P ＞ 0.05). ②Expression levels (A) of resistin protein in abdominal subcutaneous adipose tissues was (14 942±6 076), which was more higher than that in thigh subcutaneous adipose tissues (39 421±6 087). There was markedly significant difference (P ＜ 0.01).CONCLUSION: The expression of resistin protein is much greater in abdominal fat depots than in thigh fat depots, which has evaluative value for studying the episode of central obesity-induced insulin resistance and type 2 diabetes mellitus.

The expression of resistin protein in normal human abdominal, thigh, pregnant women abdominal, non-pregnant women abdominal subcutaneous adipose tissue and placenta and the relationship between obesity, type 2 diabetes mellitus (T2DM), pregnant physiological insulin resistance (IR) and gestational diabetes mellitus (GDM) was investigated. The expression of resistin protein in normal human abdominal, thigh, pregnant women abdominal, non-pregnant women abdominal subcutaneous adipose tissue and placenta was detected by using Western blotting method. Fasting serum glucose concentration was measured by glucose oxidase assay. Serum cholesterol (CHOL), serum triglycerides (TG), serum HDL cholesterol (HDL-C) and serum LDL cholesterol (LDL-C) were determined by full automatic biochemical instrument. Fasting insulin was measured by enzyme immunoassay to calculate insulin resistance index (IRI). Height, weight, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured to calculate body mass index (BMI) and body fat percentage (BF %). Resistin protein expression in pregnant women placental tissue (67 905 +/- 8441) (arbitrary A values) was much higher than that in subcutaneous adipose tissue in pregnant women abdomen (40 718 +/- 3818, P < 0.01), non-pregnant women abdomen (38 288 +/- 2084, P < 0.01), normal human abdomen (39 421 +/- 6087, P < 0.01) and thigh (14 942 +/- 6706, P < 0.001) respectively. The resistin expression in abdominal subcutaneous adipose tissue showed no significant difference among pregnant, non-pregnant women and normal human, but much higher than that in thigh subcutaneous adipose tissue (P < 0.001). Pearson analysis revealed that resistin protein was correlated with BMI (r = 0.42), fasting insulin concentration (r = 0.38), IRI (r = 0.34), BF % (r = 0.43) and fasting glucose (r = 0.39), but not with blood pressure, CHOL, TG, HDL-C and LDL-C. It was suggested that resistin protein expression in human abdominal subcutaneous adipose tissue was much higher than that in human thigh subcutaneous adipose tissue. Resistin was closely related with central obesity, leading to IR, subsequently obesity and T2DM. Resistin protein expression in placental tissue was much higher than that in subcutaneous adipose tissue in normal human abdomen, pregnant abdomen, non-pregnant women abdomen and thigh. It was indicated that resistin protein could be secreted from human placental tissue. Resistin might be one of the factors that lead to pregnant physiological IR and GDM.

Objective: To observe the effect of the outer orbicularis muscle partial resection combined with orbital fat flap or orbicularis muscle flap transfer to block orbicularis muscle for improvement of crow′s feet. Methods: From October 2010 to May 2015, 82 cases of females (aged from 27 to 54 years old) with crow′s feet were treated with new method(n=41) and traditional method(control, n=41). The new method included partial resection and orbital fat flap or orbicularis muscle flap transfer to block orbicularis muscle. The traditional method was performed to lift the skin and orbicularis oculi muscle to improve the crow′s feet. The operation time, the postoperative recovery time, eyes closing function and hematoma, nerve injury and other complications were recorded. 1, 3, 6 and 12 months after operation, the effect was assessed by one cosmetic surgeon who is unkown the groups. Completely correction was assed as 5 points and no improvement or even worse as 0 point. 12 months after operation, the patients satisfactory rate was recorded. Results: 75 cases were followed up, including 39 in new method group and 36 in control group. The operative time and postoperative recovery time were (50±5) min, (58±4) min and (5±1) d, (6.0±1.5) d in the new method group and control group respectively (P<0.05). The two groups both had good eyes closing function, no eyes closing fatigue or difficult or other serious complications such as hematoma, nerve injury. Visual analog scale were 3.2±0.6, 3.5±0.5, 4.2±0.8, 4.3±0.8 and 3.1±0.6, 3.4±0.9, 3.0±0.6, 2.8±0.5 in the new method group and control group at 1, 3, 6, 12 months after surgery respectively . Obviously, the effect in new method group was much better than that in control group after 6 and 12 months with statistical significance (P<0.05). 12 months after surgery, the satisfaction surveys showed satisfactory in 33 cases; fairly satisfactory in 4 cases; dissatisfactory in 2 cases in new method group, and satisfactory in 10 cases; fairly satisfactory in 15 cases; dissatisfactory in 11 cases in the control group, showing significant difference between the 2 groups (P<0.05). Conclusions The outer orbital orbicularis muscle partial resection combined with orbital fat flap or orbicularis muscle flap is reasonable and reliable to correct crow′s feet with short recovery and less complication. It is a worthy new method for recommendation.

Objective:To compare the detection rate of genital Chlamydia trachomatis (CT) DNA between urine and urethral/cervical swab samples. Methods:From December 2018 to December 2019, a total of 1 475 outpatients were collected from sexually transmitted disease clinics in 7 medical institutions, such as Department of Venereology, Guangzhou Institute of Dermatology, including 1 118 males and 357 females. One urethral/cervical swab sample and one urine sample were collected successively from each patient. Real-time fluorescence-based PCR was performed to detect CT DNA in urine and urethral/cervical swab samples, and paired chi-square test was used to compare the positive rate of CT DNA between the 2 kinds of samples. Random- or fixed-effect meta-analysis was conducted for the test of heterogeneity and merging of positive rates of CT DNA in the urine and urethral/cervical swabs among 7 medical institutions.Results:The positive rate of CT DNA in the urine samples was significantly higher than that in the swab samples from 4 medical institutions (all P < 0.05) , while there was no significant difference in the positive rate of CT DNA between the 2 kinds of samples from 3 medical institutions (all P > 0.05) . The heterogeneity ( I2) estimates of the CT-DNA positive rate in urine and swab samples among different medical institutions were 78.6% (95% CI: 55.9% - 89.6%) and 73.7% (95% CI: 43.7% - 87.7%) , respectively; meta-analysis showed that the total merged positive rate of CT DNA in the urine samples was 10.8% (95% CI: 7.2% - 15.9%) , which was significantly higher than that in the swab samples (7.8%, 95% CI: 4.9% - 12.1%; χ2 = 39.2, P < 0.05) . Compared with the swab sample-based CT-DNA detection method, the sensitivity, specificity, positive predictive value, negative predictive value and consistency rate of the urine sample-based CT-DNA detection method were 97.0% (128/132) , 96.3% (1 293/1 343) , 71.9% (128/178) , 99.7% (1 293/1 297) , and 96.3% (1 421/1 475) , respectively. The positive rate of CT DNA in the urine samples from 1 118 male patients was 11.0% (95% CI: 7.2% - 16.5%) , which was significantly higher than that in the swab samples (7.6%, 95% CI: 4.9% - 11.8%; χ2 = 34.3, P < 0.05) . There was no significant difference in the positive rate of CT DNA between the urine (11.9%, 95% CI: 7.7% - 17.9%) and cervical swab samples from 357 female patients (10.4%, 95% CI: 7.6% - 14.0%; χ2 = 3.2, P > 0.05) . Conclusions:The positive rate of CT DNA in urine samples is higher than or similar to that in urethral/cervical swab samples. The urine sample-based CT-DNA detection method has characteristics of convenience, non-invasiveness, painlessness and low cost, and is worthy of clinical promotion.

Objective To evaluate the clinical application of Catalyst system in positioning patients during cervical cancer radiotherapy,and to analyze its correlation with the bladder volume and body mass index (BMI) of patients.Methods A total of 33 patients diagnosed with cervical cancer from July to December 2017 in our hospital were included in the study.All patients were auxiliary positioned by an optical surface imaging system (C-Pad Catalyst) before each treatment.The CBCT imaging was executed twice a week.The setup errors from Catalyst and CBCT in the anterior-posterior (AP),superior-inferior (SI) and leg-fight (LR) directions were recorded.Each patient's bladder volume and BMI were also recorded.Results The setup errors between Catalyst with masks and CBCT had the significant difference in SI (P＜0.05) and LR (P＜0.05).For Catalyst without masks,the setup errors with the bladder volume of 200-300 ml had the significant association in SI (R=-0.316,P＜0.05).For the bladder volume of＞300 ml,the setup errors for Catalyst with masks had the significant association in AP (R=-0.493,P＜0.05),and that without masks had the significant association in SI and LR (R=0.335,P＜0.05,R=-0.348,P＜0.05).For patients of＜25 kg/m2,setup errors for Catalyst with masks had the significant association with the BMI in LR (R=0.197,P＜0.05);for ≥ 25 kg/m2,that with masks had the significant association in AP and SI (R =0.818,P＜0.05;R=-0.498,P＜0.05),that without masks had the significant association in AP and LR (R=0.652,P＜0.05;R=-0.558,P＜0.05).Conclusion Unlike CBCT system,the patient positioning by Catalyst system was easily affected by the bladder volume and BMI of patients.

Objective: To investigate the correlation between skin elasticity and setup error in optical surface image-guided radiotherapy. Methods: The skin elasticity (R7) data of the head, chest and abdomen were extracted and analyzed its correlation with age by systematic literature review. Fifty-four patients diagnosed with nasopharyngeal carcinoma, breast cancer and cervical cancer were recruited in this study. Firstly, the patients were positioned based on the room laser and markers. Subsequently, the patient position was verified by the Varian On-Board Imager, and then C-Rad Catalyst was adopted to obtain surface images in two states (mask or non-mask) as reference images. In the subsequent fraction treatment, after initial positioning, the local calibration was performed by Catalyst, and setup errors in three directions were recorded. Meanwhile, the patient setup was verified by CBCT twice a week. The Pearson correlation analysis was performed to analyze the correlation between setup error and age. Results: The skin elasticity was negatively correlated with aging (P<0.01). The correlation coefficient between random error and age in head-and-neck cancer were 0.645, 0.624 and 0.866 in the AP, SI and LR directions (all P<0.05) for male patients without mask, respectively. The system error was significantly correlated with age in the LR direction (P<0.05) for male patients, and in the AP direction (P<0.05) for female patients with head-and-neck cancer without mask. The setup error had a significant correlation with skin elasticity in male patients with head-and-neck cancer, and the sequence of absolute value of correlation coefficient was LR>SI>AP. Conclusion In optical surface-guided radiotherapy of head and neck cancer, skin elasticity may be a significant index for assessing the setup errors in male patients.
