Objective To evaluate the efficacy of topicalJinhuang unction combined with oralSangqin mixture forthe patients with moderate to severe acnevulgaris.Methods A total of 72 patients with moderate to severe acne (Pills bury grade 2 or grade 3) were included and divided into a study group and a control group by random number table method, 36 in each group. The patients were treated for 2 months in the study group with topicalJinhuang unction combined with oralSangqin mixture, and in the control group with topical fusidic acid combined with oralSangqin mixture. The number of lesions and the Global Acne GradingSystem (GAGS) score for each patient were obtained and evaluated. The number offollicularPropionibacterium acnes was determined with real-time fluorescence quantitative polymerase chain reaction.Results After treatment, the number of papule (28.69 ± 10.50vs. 36.61 ± 10.10;t=3.262,P=0.002) was significantly less than that in the control group. The pustules was 1(0, 3) and the nodules was 0 (0, 1) in the study group, which were significantly less than those of 3(0, 15) and 0 (0, 4) in the control group (P<0.01). The GAGS scores was 13(6, 24), which was significantly less than those of 20(17, 32) in the control group significantly lower (Z=-6.482,P<0.01). The number reduction rate of follicular Propionibacterium acnes per unit area in the study group were 43.07% (-57.14%, 86.23%), which was significantly higher than that of 12.68% (-34.52%, 51.11%) in the control group (Z=-2.705,P=0.007). Conclusions TopicalJinhuang unction combined with oralSangqin mixture may reduce the damage of the skin, decrease the numbers of papule, pustules and nodules, depressPropionibacterium acnes in patients with moderate to severe acne vulgaris. TopicalJinhuang unction combined with oralSangqin mixture is superior to topical fusidic acid combined with oralSangqin mixture for the treatment of moderate to severe acne vulgaris.

OBJECTIVE: To explore the significance of the combination of factor analysis and systematic cluster analysis in classification of traditional Chinese medical syndromes in patients with posthepatitic cirrhosis, and to provide a scientific basis for the criterion of the classification. METHODS: We designed a clinical questionnaire according to the clinical characteristics and the demands of traditional Chinese medical information collection for patients with posthepatitic cirrhosis. By means of clinical epidemiological research, with the four diagnosis methods for clinical information collection of traditional Chinese medicine, symptoms, physical signs, tongue conditions and pulse conditions in 310 patients with posthepatitic cirrhosis were collected, and the characteristics of traditional Chinese medical syndromes in these patients were explored with statistical methods, such as factor analysis, varimax and systematic cluster analysis. RESULTS: Analyzed by factor analysis and systematic cluster analysis with SPSS 11.0, the traditional Chinese medical syndromes in 287 of the 310 cases (92.58%) of posthepatitic cirrhosis could be classified. The syndromes could be divided into 7 categories, which were internal accumulation of damp-heat (55 cases), insufficiency of the spleen with overabundance of dampness (74 cases), accumulation of blood stasis plus deficiency of liver-yin and kidney-yin (73 cases), accumulation of blood stasis plus deficiency of both blood and qi (40 cases), deficiency of both blood and qi (16 cases), deficiency of yin and blood heat (6 cases) and stagnation of the liver-qi and deficiency of the spleen (23 cases). The traditional Chinese medical syndromes in the other 23 cases could not be classified. CONCLUSIONS: The clinical information collected with the four diagnostic methods of traditional Chinese medicine can be classified into different categories with the factor analysis and systematic cluster analysis. The factor analysis and systematic cluster analysis can reveal the characteristics and regularity of traditional Chinese medical syndromes in patients with posthepatitic cirrhosis in a way, and have value in researching the syndromes of traditional Chinese medicine.

Objective To analyze the clinicopathological features of gastric stromal tumor with primary gastrointestinal carcinoma.Methods 469 cases of gastrointestinal stromal tumor (GIST) from January 2011 to December 2014 admitted to PLA General Hospital were retrospectively analyzed.Gastric stromal tumor patients with primary gastrointestinal carcinoma were screened.The concomitant gastrointestinal cancer site,stromal tumor size,mitotic activity,immunohistochemistry were also detected.Results The gastric stromal tumor with primary gastrointestinal carcinoma accounted for 14.7 ％ (69/469) of all the GIST,in which the small gastric stromal tumor accounted for 65.2 ％ (45/69) of the total and 9.59 ％ (45/469) of all the GIST.The diameter of all tumors was ＜ 5 cm,and the mitotic was ＜ 5/50 HPF.The positive rates of CD117,CD34,DOG-1 were 92.8 ％ (64/69),92.8 ％ (64/69),94.1％ (65/69).The Fletcher was classified as low-risk and extreme low-risk.Conclusions Gastric stromal tumor with primary gastrointestinal carcinoma has no specific clinical features and pathological immunohistochemical markers.Its malgnant degree is lower than GIST.Its prognosis is associated with primary gastrointestinal cancer staging.

Objective To explore the effectiveness of the timed up and go test (TUGT) and the maximum walking speed test (MWST) in evaluating stroke patients' motor function.Methods Twenty-two stroke patients were assessed using the TUGT and MWST,and the temporal-spatial parameters of their gait were also assessed.The correlations among the TUGT times,walking speed and the gait parameters were quantified using Pearson correlation coefficients.Results The TUGT time was (18.57±7.41) s,significantly correlated with step length and velocity (P＜0.05).Walking speed showed a significant positive correlation with step length,velocity and step length (P＜ 0.05).The TUGT times were negatively correlated with walking speed (r=-0.712,P=0.000).Conclusion The MWST and TUGT both can assess stroke patients' motor function effectively.

Objective To investigate clinical and pathological features of gastrointestinal stromal tumors,the frequency and type of mutation of c-kit and platelet-derived growth factor receptor α (PDGFRA)genes.Methods 340 patients underwent surgical resection and diagnosed as gastrointestinal stromal tumors by postoperative pathology from Junuary 2012 to December 2014 were enrolled,and their tumor tissues were collected.The direct sequencing method was applied to detect the mutation status of c-kit gene (exon 9,11,13 and 17) and PDGFRA gene (exon12 and 18).Results There were 138 males and 192 females,and their median age was 58 years old (37-81 years old).There were 178 patients (52.4 ％) with gastric stromal tumors,21 cases (6.2 ％) with duodenal stromal tumors,82 cases (24.1％) with small intestinal stromal tumor,10 cases (2.9 ％) with colon stromal tumor,15 cases (4.4 ％) with rectal stromal tumors,30 cases (8.8 ％) with parenteral stromal tumor (from the peritoneum,mesentery,retroperitoneum or attachment),4 cases (1.2 ％) of liver tissues (gene detection tissues from the liver biopsy or surgical resection specimens).In the mutation analysis of all 340 patients with gastrointestinal stromal tumor,the total mutation rate was 89.4 ％ (304/340),including 81.2 ％ (276 cases) of c-kit,8.2 ％ (28 cases) of PDGFR and 10.6 ％ (36 cases) of wild type.Among 125 cases underwent the detection of the gene mutation sequences,there were 49 cases of exon11 deletion mutation,4 cases of exon11 insertion mutation,12 cases of exon 11 missense mutation,8 cases of exon9 insertion mutation,1 case of 3xon13 missense mutation,1 case of exon17 missense mutation,24 cases of exon12 synonymous mutation and 20 cases of exon18 synonymous mutation.Conclusions Gene detection is becoming more and more obvious in predicting the therapeutic effect of molecular targeted therapy,the mechanism of drag resistance and the clinical treatment,c-kit exon11 mutation is one of the most common gene mutation types related to the choice of targeted medicine.

OBJECTIVE To discuss the diagnosis and endoscopic treatment of congenital basal encephaloceles in infants.METHODS We retrospectively reviewed the clinical data of 6 infants with congenital basal encephaloceles in Beijing Children's Hospital between January 2014 to September 2016. CT and MRI were performed routinely. All patients underwent endoscopic resection of encephaloceles and repair of skull base defects. RESULTS Five patients presented with transethmoidal encephaloceles and one transsphenoidal encephaloceles. All patients underwent endoscopic procedure successfully. There were no complications except for one 7-month old girl who got purulent meningitis. All patients had favorable clinical outcomes during a follow-up of 3 to 29 months.CONCLUSION For infants with persistent nasal obstruction and nasal neoplasms, congenital basal encephaloceles should be considered. Nasal coronary CT and sagital MRI are of paramount importance in the diagnosis of congenital basal encephaloceles in infants. The endoscopic procedure is the safe and effective method for the management of congenital basal encephaloceles in infants.

Objective To control medical expenses in a rational and effective way by analyzing the main factors influencing hospitalization expenses in TCM hospitals. Methods Based on ICD 10 codes, the top 50 disease entities causing hospitalization, as had been accumulated over the years, were extracted from the hospitalization record data warehouses of the national TCM supervision networks using nationally representative medical record databases, the main factors influencing hospitalization expenses were identified using multi layer BP neural network, and further analyses were made by disease entities and hospital grades. Results When disease entity mix analyses were conducted, it was found that the variables most influencing hospitalization expenses/days were hospital code and disease entity while variables specific to TCM had little influence on the expenses. The results were also true of analyses made by hospital grades and disease entities. Conclusion Under the current circumstances in China, the influence on hospitalization expenses resulting from the difference between hospitals is far greater than any other factor; it is even greater than that resulting from the difference between disease entities. It is therefore imperative to pay attention to the extensiveness and coverage of data sources when conducting research on the control of medical expenses.

Objective The objective of the present study was to establish a template for the self assessment of hearing aids outcomes according to the evaluation of a large group of hearing aid users .Methods In total ,1 724 subjects participated in the study .The Chinese version of International Outcome Inventory for Hearing Aids (IOI-HA) was used as the evaluation tool .IOI -HA is a seven -item questionnaire ,each item is designed to assess a specific outcome domain .Each item was designed with a five -point rating scale ,a higher rating indicates better outcome .According to the subjects'self reported hearing difficulty when they were not wearing hearing aids (unaid-ed) ,the subjects were divided into two groups :self reported hearing difficulty to be no ,mild ,moderate group ,and self reported hearing difficulty to be moderately severe or severe group ,respectively .Templates for each group were established according to the analysis of the item ratings .Results One thousand two hundred and forty -seven sub-jects accept the investigation ,with a response rate of 72 .3% ,and 1203 completed responses were included in the fi-nal analysis .The Chinese version of IOI-HA scores showed a skewed distribution ,with a mean score ranging from 3 .52 to 4 .19 .The total IOI-HA scores ranged from 9 to 35 ,and the mean total score was 26 .30 .Results showed that for the self reported hearing difficulty (unaided) to be none ,mild or moderate group ,the mean scores for the i-tem of daily use ,benefit ,residual activity limitation ,satisfaction ,residual participation restrictions ,impact on others ,and quality of life were 4 .14 ,3 .67 ,3 .76 ,3 .58 ,3 .56 ,3 .93 and 3 .69 ,respectively .The corresponding mean scores for the self reported hearing difficulty (unaided) to be moderately severe or severe group were 4 .19 ,3 .63 ,3 .64 ,3 . 65 ,3 .52 ,3 .89 ,and 3 .79 ,respectively .A template for the Chinese IOI -HA was established according to the above data .Conclusion The template for the Chinese version of IOI -HA could be served as an effective tool to measure the general effectiveness of the hearing aid outcomes and hearing aid fitting in China ,which would also facilitate the international outcome comparison cross culture .

Objective To explore the best vibration frequency for activating human muscles.Methods Nineteen healthy college students accepted vibration stimulation at frequencies between 10 and 50 Hz.Surface electromyograms (sEMG) were recorded.The subjects were sitting,standing,squatting (knee flexion 30°) and recumbent.Their left anterior tibial muscles and the medial heads of the gastrocnemius were targeted as test muscles.The vibration stimulation point was on the surface of the left distal tibia.The sEMG characteristics of the calf muscles were analyzed under vibration stimulation at different frequencies. ResultsThe leg muscles were activated significantly at all vibration frequencies,but the sEMG values of the anterior tibialis were significantly different at different frequencies,except for among 30 Hz,40 Hz and 50 Hz in any position.The gastrocnemius sEMG values were not significantly different at different frequencies. ConclusionVibration at 30 to 50Hz may be the normal human muscle activation frequency.

Objective To evaluate the effect of acupuncture on the quality of recovery during the early period after gynecological laparoscopic surgery using the Quality of Recovery?40 questionnaire ( QoR?40). Methods Sixty patients, aged 20-60 yr, with body mass index of 18.5-28.0 kg∕m2, of American Society of Anesthesiologists physical status ⅠorⅡ, scheduled for elective gynecological laparoscopic surgery, were equally and randomly divided into either control group ( group C ) or acupuncture group (group Acu) using a random number table. Bilateral Neiguan (PC6) and Hegu (L14) acupoints were stimulated for 30 min starting from the time point before skin incision and immediately after the end of surgery. The quality of recovery was assessed using the QoR?40 on 1 day before surgery, and at 24 and 48 h after surgery. The patient′s cognitive function was assessed using Mini?Mental State Examination. The requirement for rescue analgesics was recorded. The occurrence of nausea and vomiting was also recorded. Results Compared with group C, the global QoR?40 and Mini?Mental State Examination scores were significantly increased, and the incidence of nausea and vomiting and requirement for rescue analgesics were decreased at 24 and 48 h after surgery in group Acu ( P<0. 05 ) . Conclusion Acupuncture can improve the quality of recovery during the early period after gynecological laparoscopic surgery using the QoR?40.
