ObjectiveTo observe the effect of acupuncture plus language function training on the recovery of language function in patients with post-stroke aphasia.MethodNinety patients were divided into an acupuncture-rehabilitation group (intervened by acupuncture plus language function training) of 30 cases, an acupuncture group (intervened by acupuncture alone) of 30 cases, and a control group (intervened by language function training alone) of 30 cases. The Western Aphasia Battery (WAB) was adopted to evaluate the language function, and also taken as criteria for diagnosis and therapeutic efficacy. The aphasia quotient (AQ), and the 4 basic language functions including spontaneous speech, auditory comprehension, repetition and nomination were observed. ResultAfter intervention, AQ, and scores of spontaneous speech, auditory comprehension, repetition and nomination increased significantly in the three groups (P<0.05,P<0.01). there were significant differences in comparing the scores of spontaneous speech, repetition and nomination between the acupuncture-rehabilitation group and the control group (P<0.05). There were no significant differences in comparing the indexes between the acupuncture group and control group (P>0.05).ConclusionAcupuncture plus language function training can produce a positive effect on patients with post-stroke aphasia, showing therapeutic advantage in improvingspontaneous speech, repetition, and nomination.

Objective To evaluate the value of the use of fibrin glue in radical mastectorny for breast cancer. Method 52 patients with breast cancer were divided randomly into two groups. In one group (27 patients) fibrin glue was used during radical mastectomy, while in the other group (25 patients), fibrin glue was not used. The volume of drainage on the first postoperative day and total volume of drainage after the operation were collected and measured. The fluid accumulation underneath the flap was also observed. Result In patients with the use of fibrin glue, the amount of drainage was much less compared with those without the use of fibrin glue. Having marked diversity ( P

ObjectiveTo observe the clinical efficacy of moxibustion plus acupoint autohemotherapy in treating allergic rhinitis due to lung-spleen qi deficiency.MethodTotally 120 eligible subjects were divided by using the random number table into a comprehensive group, a moxibustion group and a Western medication group. The comprehensive group was intervened by moxibustion plus acupoint autohemotherapy, the moxibustion group was by moxibustion,and the Western medication group was by Loratadine tablets. The acupoint autohemotherapy was give twice a week and the rest treatments were given once a day, 7 das a course, for 4 courses in total. A follow-up study was conducted 3 months later. The clinic efficacy was evaluated before and after intervention, as well as in the follow-up study.ResultThe three groups all achieved significant short-term efficacies after intervention, and the comprehensive group was equivalent to the moxibustion group, bothsuperior to the Western medication group(P<0.05). According to the follow-up study, the long-term efficacies of the comprehensive group and moxibustion group were both significantly higher than that of the Western medication group (P<0.01,P<0.05), and the moxibustion group was superior to the comprehensive group in comparing the long-term efficacy (P<0.01).ConclusionMoxibustion plus acupoint autohemotherapy and dry moxibustion both can produce significant short-term and long-term therapeutic efficacies in treating allergic rhinitis due to lung-spleen qi deficiency. The long-term efficacy of moxibustion is higher than that of moxibustion plus acupoint autohemotherapy in treating allergic rhinitis due to lung-spleen qi deficiency. Acupoint autohemotherapy requires strict aseptic operation, which restricts its application in family healthcare. Long-term use of moxibustion can activate yang qi, and thus plays a role in preventing diseases.

OBJECTIVE:To summarize the application of proteomics in the plateau medical research. METHODS:A computer-based online search was conducted in PubMed and Wanfang databases from 1995 to 2015 to screen the relevant literatures using the key words“proteomics, medical research, plateau medicine”in English and Chinese, respectively. A total of approximately 200 English and 60 Chinese relevant literatures were selected and the 59 eligible literatures were included after screening final y. RESULTS AND CONCLUSION:Currently, the human genome has been decoded through the studies on exploring the proteomics changes under the pathological conditions and the underlying mechanisms. Construction of physiological and pathological mapping based on the human proteome contributes to revealing the novel treatment targets, diagnostic markers, and drugs for the prevention and treatment of diseases. Proteomics has become the frontier and hot research field both at home and abroad, including al the proteins expressed in the tissue, cel or organism, and becomes a bridge between the genome and clinical application.

Objective To compare the high risk factors, complications, treatment and prognosis of respiratory distress syndrome (NRDS) in neonates at different gestational age (GA). Methods Between August 2012 and July 2013, 156 neonates with RDS were selected and distributed into 3 groups, 42 early preterm (GA<34weeks), 52 late preterm (GA 35 to 36 weeks), and 62 in term group (GA≥37 weeks). Retrospectively analysis was performed for high risk factors, complications, treatment and prognosis of the three groups. Results In 156 neonates with RDS, the male and female proportion was 2.25:1. All groups had more males, but the gender difference has no statistical signiifcance in three groups (P=0.923). The onset time of RDS and the hospitalization time both show an increasing trend of statistical signiifcance (P<0.05). Comparing the difference of high risk factors for RDS of the 3 groups, birth asphyxia, placental abnormalities, multiple pregnancy, premature rupture of membranes was most common in early preterm group, and followed by late preterm group, and C-section was most common in term group and unexplained preterm was more common in early preterm group than that in late preterm group (all P<0.05). Among the three groups, the ratio of pulmonary surfactant application was the lowest in the term group, the ratio of X-ray grade over II was high-est in early preterm group, oxygen and hospitalization time were the longest in early preterm group (P<0.05). The risks of com-plicated with pulmonary infection, intracranial hemorrhages and bronchopulmonary dysplasia were the highest in early preterm group and the risk of complicated pneumothorax was the highest in term group. Among three groups, the recovery rate was the lowest in the early preterm group (P<0.01). Conclusion The clinical characteristics, high risk factors, complications and treat-ment responses of RDS in neonates with different GA were different, so GA should be considered for diagnose and treatment. For the term infants, the elective caesarean section should be strictly controlled, in order to reduce the incidence of RDS.

Objective: To evaluate the status of loneliness, the influential factors and the relationship between loneliness and family function among bereaved parents in disaster area of 5.12 Earthquake and to provide basis for mental and family reconstruction for those people suffering from the Earthquake. Methods: A total 190 bereaved parents in disaster area of 5.12 Earthquake were enrolled for an across-sectional study. A face-to-face survey was conducted by following scales: General Data Scale, University of California at Los Angels Loneliness Scale, Emotional and Social Loneliness Scale and Family APGAR Index. Results: hTe score of loneliness ranged from 24 to 69 (mean=43.58, SD=9.61), the score of emotional loneliness ranged from 5 to 24 (mean=11.95, SD=3.60) while the social loneliness ranged from 6 to 24 (mean=13.99, SD=3.69). hTe scores of loneliness, social loneliness and emotional loneliness were all increased among bereaved parents compared to people without loss of their child. The results of multivariate analysis showed that family function and status of fertility significantly impacted the loneliness (P<0.05). Furthermore, there was negative correlation between family function and the loneliness, social loneliness and emotional loneliness (P<0.05). Conclusion: The bereaved parents in disaster area of 5.12 Earthquake showed higher level of loneliness. The better of family function indicated the less of loneliness in bereaved parents. Measures should be taken to promote mental and family reconstruction for such people, including providing effective skills to improve emotional communication and family function and offering technical support for having another baby.
