Objective:To observe the clinical effect of acupuncture combined with tuina manipulation for thoracic facet joint disorder. Methods:A total of 93 eligible cases were randomly allocated into an observation group and a control group. Patients in the observation group (n=46) were treated with acupuncture combined with tuina manipulation, whereas patients in the control group (n=47) were treated with tuina manipulation alone. The treatment was done once a day, for a total of 3 times. Therapeutic efficacies were then evaluated according to scores on signs and symptoms.
Results:After treatment, there were intra-group statistically significant differences in scores of eight signs and symptoms (all P<0.01); and the between-group differences were statistically significant in scores of eight signs and symptoms (all P<0.05). After three times of treatment, the recovery rate in the observation group was 54.4%, versus 25.4% in the control group, showing a statistical significance (P<0.05).
Conclusion:Acupuncture combined with tuina manipulation can obtain better effects than tuina manipulation alone for thoracic facet joint disorder and is therefore worth further clinical application.

Objective To explore the diagnosis and treatment of phyllodes tumor of the breast. Methods Clinical data from 30 patients with phyllodes tumor confirmed surgically and pathologically were analyzed retrospectively. Results Of the 30 cases of phyllodes tumor, there were 16 cases of benign tumor, 9 cases of borderline tumor and 5 cases of malignant tumor according to the standard histological criteria. Local mass excision, total mastectomy, modified radical mastectomy and tumor mass excision were performed in 8, 8 and 13 patients, and 1 patient, respectively. A follow up of 20 cases for 1-24 years found 1 death, but all the others survived. Four patients out of the 20 patients underwent total mastectomy or modified radical mastectomy due to tumor recurrence. Conclusion The preoperative diagnosis of phyllodes tumor is difficult. Intraoperative frozen section examination of the suspicious lesions should be conducted. Multiple slices of the specimen should be performed. Surgical options are closely associated with the prognosis. Wide local excision or total mastectomy is recommended in surgical options.

Objective:To explore effect for isoproterenol rising detection rate of paroxysmal supraventricular tachy‐cardia by transesophageal atrial pacing (TEAP) .Methods :A total of 85 patients with suspected PSVT attack history received routine TEAP ( basic stimulate ) ,for those failed to evoke PSVT ,they received additional intravenous infusion of isoproterenol to make heart rate rise to 120 beats/min ,then TEAP was repeated .Results :Routine TEAP evoked PSVT in 29 cases (34.1% ,29/85) ;among the remaining 56 cases un - evoked PSVT ,after intravenous infusion of isoproterenol PSVT was evoked in 54 cases (96.4% ,54/56) by TEAP ,and this detection rate was significantly higher than that of routine TEAP (96.4% vs .34.1% , P = 0.039) .Conclusion :Intravenous infusion of isoproterenol can greatly raise the detection rate of paroxysmal supraventricular tachycardia by transesophageal atrial pacing .

Objective To study the association of ER? expression with the expression of hormonal receptor and prognostic biomarkers.Methods The expressions of ER?,ER?,PR,Ki-67,HER-2/neu and p53 were detected in tissue samples from 109 breast cancer patients by immunohistochemistry on tissue microarray slides.The histologic grade,tumor size and lymph node metastasis status of 109 cases of breast cancer were recorded and served as comparison indexes.Results ER? was expressed in benign epithelium and stroma cells,and breast cancer cells in 59% breast cancer tissues of different histologic types.ER? was coexpressed with ER? in 45% breast cancer tissues.ER? expression was found a statistically significant association with HER-2/neu(P

Nuclear magnetic resonance (1H-NMR) fingerprint of Rhodiola rosea medicinal materials was established, and used to distinguish the quality of raw materials from different sources. Pulse sequence for water peak inhibition was employed to acquire 1H-NMR spectra with the temperature at 298 K and spectrometer frequency of 400.13 MHz. Through subsection integral method, the obtained NMR data was subjected to similarity analysis and principal component analysis (PCA). 10 batches raw materials of Rhodiola rosea from different origins were successfully distinguished by PCA. The statistical results indicated that rhodiola glucoside, butyl alcohol, maleic acid and alanine were the main differential ingredients. This method provides an auxiliary method of Chinese quality approach to evaluate the quality of Rhodiola crenulata without using natural reference substances.

Objective:A study was conducted to observe and compare the efficacy and safety of endostar combined with peme-trexed in elderly patients with advanced lung adenocarcinoma. Methods:Sixty advanced lung adenocarcinoma (ⅢB-Ⅳ) patients who never received any therapy were included. The patients were divided into two groups. One group comprised endostar treatment com-bined with pemetrexed (26 cases of males, 15 cases of females, and 11 cases of individuals aged 65 years old to 78 years old), and the other group comprised pemetrexed only (34 cases of males, 20 cases of female, and 14 cases of individuals aged 65 years old to 78 years old). The two groups were treated for 4 to 6 cycles, and evaluation of treatments was performed every two cycles. Results:The endostar group was re-treated for 80 cycles, and the average cycle was 3.1. The group without endostar was re-treated for 115 cycles. The short-term effects are as follows. The total effective rates (RRs) in the experimental and control groups were 23.1%and 14.7%, re-spectively, and the difference was statistically significant (P<0.05). The disease control rate (DCR) was not significantly different (P>0.05). For pleural effusion, RR and DCR were significantly better in the experimental group than in the control group (P<0.05). In the experimental group, compared with PD, the microvessel density (MVD) in the DCR showed higher expression, and a statistically signif-icant difference (P=0.03) was observed. In the control group, compared with PD, the MVD in the DCR also showed higher expression, but no significant difference (P=0.73) was observed. The long-term effects were as follows: median progression-free survival (PFS), median survival, and side effects between the two groups were not significantly different (P>0.05). Conclusion: Endostar combined with pemetrexed showed increase in total efficiency in elderly patients with lung adenocarcinoma, and malignant pleural effusion was controlled without increasing the toxicity of chemotherapy. MVD can be used as a predictor of Endostar application.

Objective To investigate the efficacy and safety of acute normovolemic hemodilu-tion for pregnant women with total placenta pravia and accreta.Methods Fifty-two pregnant women with placenta praevia and accreta were randomly divided into three groups.Groups A and B received ANH or AHH before the operation while group C received the normal treatment.The total blood loss,transfusion of allogeneic blood and preoperative and postoperative routine blood test were recor-ded;the infants’umblical artery blood samples were taken immediately after birth,and 1 min,5 min Apgar scores and the blood gas was analyzied.Results There were no significant difference in the general condition,operation duration,blood loss among the three groups;the transfusion of allogeneic blood in groups B and C were much more than group A (P <0.05);the postoperative hemoglobin and hematocrit and the count of plateletsin in group A were better than groups B and C (P <0.05),while there were no statistically difference between groups B and C;there were not only seldom difference in the Apgar scores of 1 min and 5 min,but also barely change in the blood gas analysis of umbilical ar-tery in new borns from the three groups.Conclusion ANH could play an important role in the pre-vention of postpartum hemorrhage without doing any harm to the mother and infant.

Objective To explore the influencing factors of disabled elderly caregivers' resilience,and to provide evidence for further intervention studies.Method Totally 221 caregivers in several communities were investigated with self-design general questionnaire,Activity of Daily Living Scale (ADL),ConnerDavidson Resilience Scale(CD-RISC) Chinese version,Simplified Coping Style Questionnaire(SCSQ),General Self-Efficacy Scale(GSES) and Perceived Social Support Scale (PSSS).Results The caregivers' resilience score was 59.99 ± 15.86,at a medium level and lower compared with normal population (t =-5.07,P＜0.01).It was positively correlated with the positive coping(r=0.468,P＜0.01),general self-efficacy (r=0.546,P＜0.01)and perceived (r=0.372,P＜0.01).Multiple stepwise regression analysis showed the positive coping,self-efficacy and social support of caregivers were influencing factors of caregivers' resilience (P＜0.01).Conclusion Disabled elderly caregivers' resilience is lower than the general population,and implementation of the intervention should be taken according to different resilience levels at clinical practice.
