OBJECTIVETo observe the clinical effect of float needle therapy combined with reperfusion activity for pain induced by cyclomastopathy.

METHODSThirty-five female patients with cyclomastopathy were randomly divided into a comprehensive group (18 cases) and a float needle group (17 cases). In the comprehensive group, float needle manipulation was used at the centre of the biceps brachii belly or the ligature between the affected nipple and breast nodule, about 4 cm beside the exterior margin of the breast, and the reperfusion activity of the affected upper limb and breast was combined. In the float needle group, simple float needle therapy was adopted. In the two groups, treatment was started 7 ± 3 days before menstruation, once every other day. After 3-time treatment, the changes of short form McGill Pain Questionnaire (SF-MPQ) scores before and after treatment, the time of pain relieved during the first treatment, recurrence in 3 months after treatment and the adverse reaction were observed. Also, the clinical effects of the two groups were compared.

RESULTSImmediately at the end of the first treatment,after 3-time treatment and while followed up for one month, each item score and the total score of SF-MPQ were decreased apparently than the scores before treatment (all P < 0.05), and all the scores mentioned above of the comprehensive group were declined more obviously than those of the float needle group (all P < 0.05). The time of pain relieved during the first treatment of the comprehensive group was much shorter than that of the float needle group [(94.72 ± 33.67) s vs (162.06 ± 29.16) s, P < 0.01]. The recurrence rate of the comprehensive group in 3 months after treatment was 5.9% (1/17), which was better than 20.0% (3/15) of the float needle group (P < 0.01).

CONCLUSIONFloat needle therapy combined with reperfusion activity and simple float needle therapy can both safely and effectively improve cyclomastopathy, and the combination therapy is better than simple float needle therapy in the aspects of pain relieving effect at once and the long term effect.

UNLABELLEDOBJECTIVE; To evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) of qi-yin deficiency phlegm-stasis inter-obstruction syndrome (QYDPSIOS), and to observe its effect on inflammatory factors and fibrinolytic factors.

METHODSBy adopting a randomization grouping, parallel control, and prospective study, 73 T2DM patients of QYDPSIOS were assigned to two groups by random digit table, the Pioglitazone Tablet group (36 cases, as the control) and the JTXZC group (37 cases). All patients maintained their basic therapies and lifestyle as previous after recruitment. Patients in the JTXZC group took JTXZC, 4 pills each time, three times per day, while those in control group took Pioglitazone Tablet, 15 mg each time, once daily. The therapeutic course for all was 8 weeks. The body weight (BW), the height, body mass index (BMI), waist circumference (WC), hip circumference, waist-to-hip ratio (WHR), and scoring of Chinese medicine (TCM) symptoms were observed. Levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h PBG), glycated hemoglobin (HbA1c), tumor necrosis factor alpha (TNF-alpha), nuclear factor kappaB (NF-kappaB), and plasminogen activator inhibitor 1 (PAL-1) were detected. The safety indices such as liver and renal functions and adverse reactions were also observed.

RESULTSCompared with before treatment, BW, BMI, HbA1c, and PBG were obviously lower after 8-week treatment than before treatment in the JTXZC group (P < 0.05). There was no statistical difference in post-treatment BW, BMI, HbA1c, or 2 h PBG between the two groups (P < 0.05). Compared with before treatment, levels of TNF-alpha and PAI-1 were lowered after 8 weeks of treatment in both groups (P < 0.01). The level of NF-kappaB was obviously lowered after 8 weeks of treatment in the control groups (P < 0.05), but it also decreased in the JTXZC group with no statistical difference. The scorings of CM symptoms were somewhat improved after treatment in the two groups (P < 0.01). Besides, better effects were obtained in the JTXZC group (P < 0.05). No severe adverse event occurred in either group during the whole therapeutic course.

CONCLUSIONSJTXZC showed similar therapeutic effect to pioglitazone. Both of them could effectively improve patients' clinical symptoms, the inflammation and fibrinolytic activities in different pathways, with no severe adverse reaction.

AIM: To compare the clinical results of suture method and partial eyelash resection treating for pediatric eyelid trichiasis, and screen an effective method for the treatment of pediatric lower eyelid trichiasis.
METHODS: Fifty-six cases of pediatric patients with lower eyelid trichiasis were randomly divided into a control group and an observation group in accordance with the method of drawing lots, and each group was 28 cases. The control group was treated with suture method, and the observation group was treated with partial eyelash resection. The clinical efficacy, patient satisfaction before and after treatment, and the incidence of complications were compared.
RESULTS:(1) The clinically total effective rate was 74%of the control group, which was 89% of the observation group, and there were statistical differences of the clinical efficacy between the two groups ( P<0. 05 ); ( 2 ) the satisfaction scores were (3. 89±1. 22) points and (6. 27±1-86) points of the the control group before and after treatment, which were ( 4. 00±1. 34 ) points and ( 8-95±2-34) points of the observation group, and there were statistical differences of the two groups before and after treatment (P<0. 05), and the scores of the observation group were higher than that of the control group ( P<0-05);(3) complications such as swelling and stitches off appeared in both groups, and the rate was 21% in the control group, which was 11% in the observation group, and there were statistical differences between the two groups (P<0. 05).
CONCLUSION: The treatment of children with lower eyelid trichiasis, suture method is simple and can be performed under local anesthesia in collaboration with children, but with a higher relapse rate, some patients required reoperation;partial resection of eyelashes can be more thoroughly solve the problem of pediatric eyelid trichiasis with low recurrence rate, but children need to be under general anesthesia with some of big risk. So partial resection of eyelashes is unsuitable for using in clinical practice widely and can be used in special cases.

Background Vitronectin is a glycoprotein that has a variety of functions.Its expression was markedly higher in the retina of oxygen induced mice,which was confirmed in our animal model,and also increased in human umbilical vein endothelial cells (人 UVECs) that were cultured in high glucose.However,there was no evidence that showed vitronectin was involved in retinal neovascularization.Objective This study was to observe the influence of vitronectin on cytoskeleton remodeling,cell migration and blood vessel formation in 人 UVECs conditioned by high glucose.Methods 人 UVECs were cultured in high glucose and the expression of vitronectin was knocked down using RNA interference technology.The experiments were divided into the high glucose group (人 UVECs were conditioned with DMEM medium that contained 50 mmol/L glucose),negative interference group (人 UVECs were transfected with control siRNA in advance,and then were conditioned with DMEM medium that contained 50 mmol/L glucose) and positive interference group (HUVEC were transfected with vitronectin siRNA in advance,and then were conditioned with DMEM medium that contained 50 mmol/L glucose).The protein expression of vitronectin was measured by Western blot,and the microfilament cytoskeleton of 人 UVECs was examined by immunofluorescence cytochemical staining followed by fluorescence microscopy.Cell migration ability in a scratch wound assay and blood vessel formation ability in a matrigel assay of 人 UVECs were evaluated.The general differences were analysed by One-Way ANOVA ;further contrasts of the two groups were analysed by the LSD-t test.Results The differences in vitronectin expression of the three groups were not obvious at 0 hour (F=1.064,P＞0.05).After 24 hours,vitronectin expression was highest in the high glucose group,lower in the negative interference group,and the lowest in the positive interference group,and the differences were significant (F =15.519,P＜0.05).After 48 hours,vitronectin expression of the three groups displayed the same pattern,and the differences were also significant (F=37.521,P＜0.05).Immunofluorescence showed that the cytoskeleton structure was most obvious in the high glucose group,moderate in the negative interference group,and was the least obvious in the positive interference group,after both 24 hours and 48 hours.In the scratch wound assay,the cell migration ability of the high glucose group was the highest,lower in the negative interference group,and the lowest in the positive interference group after 24 hours,and the differences were significant (F=90.685,P＜0.05).After 48 hours,the cell migration abilities of the three groups displayed the same pattern,and the differences were also significant (F=67.880,P＜0.05).In the matrigel assay,after 6 hours,the number of blood vessels formed in the high glucose group was more than that in the negative interference group,and the least amount was found in the positive interference group.The differences among of them were significant (F =86.653,P＜0.05).The number of blood vessel formed in the positive interference group was also the lowest after 12 hours,and the differences were also significant (F=18.992,P＜0.05).Conclusions Vitronectin can bring about cytoskeleton remodeling,increase in cell migration,and enhancement of blood vessel formation in 人 UVECs conditioned in high glucose.It may be one of the important influence factors of diabetic retinopathy.

AIM: To test the ability of multifocal visual evoked potential (mfVEP) in the detecting of glaucoma by comparing the mfVEP recorded from normal subjects and glaucoma patients.METHODS: The mfVEP of 32 normal eyes (n =21) and of 58 eyes (n =37) with primary glaucoma were recorded with the Vision Monitor electrophysical apparatus by the second kernel analysis and to determine the correlation of the topographic location between them.RESULTS: There were significant variability (the coefficient of variation was 43.05%) in mfVEP RMS amplitude in the normal subjects; The RMS amplitude of eyes with glaucoma were smaller than that of the normal eyes and significantly statistical difference were found in the relatively center (namely the 0° -10° ring zone) and in superior nasal quadrant (P＜0.05) while there were no significantly statistical differences of the latency time between them.CONCLUSION: The normal subjects have large individual variability of mfVEP responses. The RMS amplitude of the mfVEP of glaucomatous eyes descends, especially in center zone and superior nasal quadrant.
