Objective To observe the effect of fructose(Fru),glucose (Glc)and exogenous nitric oxide donor sodium nitroprusside(SNP)on the germination of Psychotria rubra(Lour.)Poir. seeds under drought stress,and to explore the optimal concentration for clearing the drought stress. Methods We established the drought stress model of Psychotria rubra(Lour.)Poir. seeds with 15％(volume fraction)PEG6000 and 0.4 mol/L D-mannitol, measured the germination rate and germination index of Psychotria rubra (Lour.)Poir. seeds under drought stress combined treatment with different concentrations of Fru (0,300,500 μmol/L),Glc (0,300,500 μmol/L) and SNP(0 , 100 , 200 μmol/L). Results The germination process of Psychotria rubra(Lour .) Poir . seeds was significantly suppressed by drought stress. Fru,Glc and SNP could significantly promote the germination of Psychotria rubra (Lour.) Poir. seeds under drought stress. The optimal condition for clearing drought stress induced by 15％ PEG6000 was Fru 300 μmol/L, Glc 500 μmol/Land SNP 200 μmol/L, and the germination rate was 95％ under the optimal condition . The optimal condition for clearing drought stress induced by D-Mannitol was Fru 500 μmol/L, Glc 500 μmol/L and SNP 100 μmol/L, and the germination rate arrived to100％. Conclusion Fru,Glc and SNP can significantly alleviate the negative impact induced by drought stress for the Psychotria rubra(Lour.)Poir. seed germination,improve the drought-resistant ability of the seeds.

Objective To study the antiviral effect of Jin Qiao Tablets on influenza A H1N1 virus in vivo. Methods The mouse pneumonia model was established by nasal inhalation of 15 LD50 of influenza virus. After prophylactic or therapeutic medication for 5 d,mouse lung tissue was taken out and weighed. Viral load in lung tissue was measured by polymerse chain reaction(PCR),and the level of γ-interferon(γ-IFN)in rat serum and lung was detected by double antibody sandwich enzyme-linked immunosorbent assay (ELISA)for evaluating the effect of Jin Qiao Tablets on lung index, viral load and γ-IFN in rats. After prophylactic or therapeutic medication for 7 d,morbidity and mortality within 14 d of mice with pneumonia induced by nasal inhalation of 3 LD50 were observed to evaluate the action of Jin Qiao Tablets for protecting against death and prolonging life span. Results Jin Qiao Tablets markedly decreased the increased lung index,promoted the death-protection rate and life-prolongation rate, decreased viral load, raised the level of γ-IFN in mice (P < 0.05 or P < 0.01). Experimental results in vivo showed that Jin Qiao Tablets had better anti-influenza virus activity than Yinqiao Jiedu Tablets and Lianhua Qingwen Capsules, and the effect of Jin Qiao Tablets was equivalent to that of Tamiflu. The prophylactic effect of Jin Qiao Tablets was stronger than the therapeutic effect, but there was no significant difference between them. Conclusion Jin Qiao Tablets have obvious effect against influenza A H1N1 virus in vivo.

Objective To investigate the effect of early-stage acupuncture therapy on local glucose metabolism in model rats with cerebral ischemia. Methods Eighty three-month-old SD rats were randomly divided into 4 groups,namely normal group,model group,2-h acupuncture group and 24-h acupuncture group,20 rats in each group. Craniotomy was used to establish the rat model of acute cerebral ischemia. Acupuncture treatment was carried out on acupoint of Baihui(GV20)and Renzhong(DU26)with reducing method,needle twirling and rotating frequency being 120 times per minute,once every other 4 min and for one min,and the total needling time for 30 min. Rats in 2-h acupuncture group were given acupuncture 2 h after the successful modeling,and once again after 24 h,two times in total;rats in 24-h acupuncture group were given acupuncture only for one time 24 h after successful modeling. At the end of treatment,the rat neurological function was scored,and the infarction area was measured by 2,3,5-triphenyltetrazole chloride (TTC)staining. The protein expression levels of glucose transporter(GLUT)1 and 3 in ischemic brain tissue were detected by immunohistochemistry. Results Compared with the normal group, the scores of neurological function in the model group were increased;TTC staining results showed that the left hemisphere was swollen,and the infarct volume was significantly larger than that of the contralateral side;immunohistochemical results showed that the GLUT1 and GLUT3 expression levels in the ischemic brain tissue were increased(P < 0.01). Compared with the model group,2-h acupuncture group and 24-h acupuncture group could effectively improve the cerebral ischemia, reduce the neurological function indexes and infarction area showed by TTC staining,and increase the expression levels of GLUT1 and GLUT3 in ischemic brain tissue significantly (P<0.05). And the therapeutic effect of 2-h acupuncture group was superior to that of 24-h acupuncture group(P<0.05). Conclusion Acupuncture can effectively improve cerebral ischemia in rats with acute cerebral ischemia. Acupuncture can improve the energy metabolism of ischemic brain tissue by up-regulating the protein expression of cerebral GLUT1 and GLUT3 and by increasing the blood-brain barrier transport efficiency for glucose,thus to promote glucose metabolism and provide energy for ischemic brain tissue to relieve relatively inadequate energy, and to protect against cerebral ischemic injury. Early acupuncture intervention exerts a positive effect on regulating energy metabolism of rats with cerebral ischemia.

Objective To explore the actions of vagus nerve in electroacupuncture (EA) with unblocking and regulating needling therapy for the treatment of mammary gland hyperplasia(MGH)with liver stagnation type, and to provide experimental evidences for clinical usage of EA with unblocking and regulating needling therapy. Methods Sixty healthy SD rats were randomly divided into 5 groups,namely blank control group,model control group,EA group,EA with disconnection of vagus nerve group,and sham-operation EA group,12 rats in each group. Except for the blank control group, the rats in the remaining groups were modeled. After successful establishment of the model of mammary gland hyperplasia (MGH) with liver stagnation type, the rats in EA group with disconnection of vagus nerve were given disconnection of unilateral vagotomy operation, the rats in sham-operation EA group were given sham operation, and EA group had no treatment, and then all of the 3 treatment groups were given EA with unblocking and regulating needling therapy. At the end of the experiment, the diameter and height of rat nipple were measured,the serum contents of estradiol (E2)and progestin (P)in the rats were detected by enzyme-linked immunoassay(ELISA),and the contents of anti-estrogen receptor alpha (ERα)and anti-progesterone receptor(PR)in the rat breast tissue were detected by immunofluorescence double staining and Western blotting method. Results (1)EA treatment can obviously improve the diameter and height of MGH rat nipple, but the therapeutic effect of EA group with disconnection of vagus nerve was not obvious. (2)Compared with the model control group,the levels of serum E2 and mammary ERαwere markedly reduced(P<0.01),and serum P level and mammary PR content were obviously increased in EA group and sham-operation EA group (P < 0.01). However,the above indexes had no obvious changes in EA group with disconnection of vagus nerve (P>0.05). Conclusion The therapeutic mechanism of EA with unblocking and regulating needling therapy for liver-stagnation MGH may be closely related with the regulation of vagus nerve.

Objective To study the microRNA-related mechanism of acupuncture in promoting postoperative gastrointestinal motility of patients with colorectal cancer. Methods Thirty cases of postoperative gastrointestinal motility disorder patients with colorectal cancer were randomly divided into acupuncture group and control group, 15 cases in each group. The control group received conventional symptomatic and supportive therapy, and acupuncture group received acupuncture at bilateral foot triple points of Zusanli,Sanyinjiao,Taichong daily on postoperative day 1-5 on the basis of conventional therapy for the control group. Time for the first anal exsufflation and time for the first defecation after operation were observed for the evaluation of clinical efficacy. Meanwhile, miR-19a expression level in serum and miR-222 expression level in the cancer tissue were detected by polymerase chain reaction (PCR). Results (1)The total effective rate of acupuncture group was 80.0％,and that of the control group was 46.7％,the difference being significant (P<0.05). (2)Time for the first anal exsufflation and time for the first defecation after operation in acupuncture group were shorter than those in the control group, the difference being significant (P < 0.05). (3) Serum miR-19a expression level in acupuncture group was decreased obviously on postoperative day 5 compared to day 1 (P < 0.05), and the decrease in acupuncture group was superior to that in the control group (P<0.05). (4)The expression of miR-222 in the cancer tissue was positively relevant to time for postoperative first anal exsufflation in both groups (P<0.05),and the expression level in ineffective patients was higher than that in effective patients (P < 0.05). Conclusion Acupuncture can regulate serum miR-19a expression level and promote the recovery in postoperative gastrointestinal motility of patients with colorectal cancer. The recovery of postoperative gastrointestinal motility in patients with colorectal cancer and the acupuncture effect are affected by miR-222 expression in the cancer tissue.

Objective To investigate the curative effect of YU Yun pulse-feeling-based acupuncture therapy for the treatment of middle-late liver cancer. Methods A total of 60 middle-late liver cancer patients were divided into control group and treatment group by stratified randomization method,30 cases in each group. The control group was given integrated Chinese and western medicine therapy according to the clinical pathway, including anti-cancer treatment such as vascular interrention,molecular targeted therapy,chemotherapy,radio therapy, and focal ablation therapy,as well as chinese medicine treatment based on disease differentiation and syndrome differentiation. And the treatment group was given YU Yun pulse-feeling-based acupuncture therapy on the basis of treatment for the control group. The two groups received 12-week treatment, and then their curative effects were compared. Results The treatment group had better effect on increasing the survival rate, prolonging survival time, improving the scores of clinical symptoms, stabilizing tumor size, and increasing the scores of Karnofsky Performance Status (KPS)than the control group,the difference being significant (P < 0.05 or P <0.01). Conclusion YU Yun pulse-feeling-based acupuncture therapy exerts certain curative effect for the treatment of middle-late liver cancer.

Objective To analyze the distribution of traditional Chinese medicine(TCM)syndromes in patients with acute pulmonary embolism(APE)and to summarize the medication rule,so as to supply evidence for the clinical diagnosis and treatment of APE. Methods A retrospective study was carried out in the APE inpatients admitted in the First Affiliated Hospital of Guangzhou University of Chinese Medicine in recent 4 years. The general data, clinical manifestations at the attack of APE, TCM syndromes, treatment and prognosis of the included patients were input into the database for the analysis of TCM syndrome distribution and medication rule. Results A total of 139 cases of APE patients were included into the study. The main manifestations at admission were dominated by dyspnea and chest pain, pale or darkish red tongue, string pulse and deep pulse. TCM syndromes were divided into three types, phlegm turbidity syndrome, blood stasis syndrome and yang collapse syndrome. The blood stasis syndrome accounted for the largest proportion and then came the phlegm turbidity syndrome. In various age groups,the 3 syndrome types accounted the highest proportion in the age group of 51-70 years old, and accounted higher proportion in the age group over 71 years old. Blood stasis syndrome was frequently seen in the age group below 30 years old. Xuefu Zhuyu Decoction and Tao Hong Siwu Decoction were frequently used for the treatment of blood stasis syndrome, Gualou Xiebai Banxia Decoction and Wendan Decoction were often used for the phlegm turbidity syndrome, and Shenfu Injection was often used for yang collapse syndrome. Conclusion APE occurs in various clinical departments, and phlegm turbidity syndrome, blood stasis syndrome and yang collapse syndrome are the main syndrome patterns of APE. Blood stasis syndrome accounts the largest proportion in clinic. Therefore, Xuefu Zhuyu Decoction and Tao Hong Siwu Decoction, Gualou Xiebai Banxia Decoction and Wendan Decoction should be used as the indicated recipes for APE to activate blood and remove stasis, strengthen spleen and resolve phlegm.

Objective To observe the clinical curative effect of meridian skin region drainage therapy for nerve root type of cervical spondylosis by comparing to the conventional acupuncture. Methods A total of 84 cases of cervical spondylosis were randomly divided into acupuncture group and drainage group,42 cases in each group. The drainage group was given meridian skin region drainage therapy including skin scraping, bloodletting combining with I-shaped acupuncture (acupuncture on Fengchi penetrating Fengfu,C3-C6 spinous process, Dazhui, Jianzhongshu, Jianwaishu), once a day. The acupuncture group was given conventional acupuncture mainly on Ashi points, cervical Jiaji acupoints, combining with Tianzhu, Dazhui, and Houxi, once a day. Seven times constituted one treatment course and the treatment for the two groups lasted 3 courses. During the treatment,time for the relief of the primary symptoms and signs of the two groups was observed,and pain index was evaluated with Visual Analogue Scale(VAS). After treatment , the total clinical efficacy and safety were evaluated,and the recurrence rate was investigated during the follow-up. Results(1)The total clinical efficacy of the drainage group was 95.2％ and that of the acupuncture group was 83.3％, and there were significant differences between the two groups(P < 0.05).(2)During the treatment,time for the relief of tenderness, time for the relief of pain, and time for the improvement of range of motion in the drainage group were much shorter than those in the acupuncture group (P<0.01). (3)After treatment,VAS scores of the two groups were decreased(P<0.01 compared with those before treatment),and the decrease in the drainage group was superior to that in the acupuncture group(P < 0.05).(4)The 2-month follow-up showed that the recurrence rate of the drainage group was 17.6％,and that of the acupuncture group was 38.1％,the difference being significant (P<0.05).(5)During the treatment,no obvious adverse event occurred in the two groups. Conclusion Meridian skin region drainage therapy exerts certain therapeutic effect for nerve root type of cervical spondylosis.

Objective To observe the therapeutic effect of Taoshi Jiangu Decoction for osteoporosis(OP). Methods A total of 120 cases of OP patients were randomly divided into treatment group and control group ,60 cases in each group. Patients in the treatment group were treated with Taoshi Jiangu Decoction orally,and those in the control group were treated with Caltrate D and Alendronate Sodium Tablets orally. Four weeks constituted one treatment course, and the treatment for the two groups covered 3 courses. The therapeutic effect of the two groups was evaluated by the changes of traditional Chinese medicine(TCM)syndrome scores,urine hydroxyproline (U-HYP),serum bone Gla-protein (BGP or osteocalcin),serum alkaline phosphatase (ALP),urine calcium (U-Ca),tartrate resistant acid phosphatase (TRAP), bone mass density(BMD) and quantitative CT(QCT) before and after treatment. Results (1)After treatment, the TCM syndrome scores of the two groups were decreased(P<0.05 compared with those before treatment),and the decrease in the treatment group was superior to that of the control group (P < 0.05). (2)After treatment,the levels of bone formation indexes of ALP and BGP were increased,and the levels of bone resorption indexes of U-HYP,U-Ca and TRAP were decreased in the two groups (P<0.05 compared with those before treatment). The effects of the treatment group were superior to those of the control group,the difference being statistically significant(P < 0.05).(3)After treatment,BMD of lumbar vertebrae 2-4 (L2-L4),neck of femur,Wards triangle and trochanter of femur,and QCT values of left neck of femur were obviously increased in the two groups (P < 0.05 compared with those before treatment). The treatment group showed stronger effect on increasing BMD and QCT values than the control group, the difference being statistically significant (P < 0.05). Conclusion Taoshi Jiangu Decoction can restrain bone absorption , promote bone formation and increase BMD, showing certain therapeutic effect for OP.

Objective To observe the effects of Qingyuan Shenghua Decoction on cardiovascular indexes and illness severity in sepsis patients after severe bone trauma. Methods Forty-eight sepsis patients after severe bone trauma were randomly divided into control group(22 cases)and treatment group(26 cases). The two groups were given routine treatment of western medicine according to International Guidelines for Management of Severe Sepsis and Septic Shock (2012). Additionally,the treatment group was treated with oral use or intranasal use of Qingyuan Shenghua Decoction, a herbal medicine recipe mainly composed of Radix Astragali, Radix Salviae Miltiorrhizae,Radix Angelicae Sinensis,Radix Paeoniae Rubra,Radix et Rhizoma Rhei,Rhizoma Curcumae, and Flos Carthami. Before and after treatment,we observed the mean arterial pressure(MAP),central venous pressure(CVP), heart rate(HR), arterial blood lactic acid(Lac), central venous blood oxygen saturation (ScvO2),central venous-arterial blood carbon dioxide partial pressure difference (Pcv-aCO2),acute physiology and chronic health evaluation system Ⅱ(APACHE Ⅱ) scores , sequential organ failure assessment (SOFA) scores, and oxygenation index (PaO2/ FiO2) of the two groups. Results With the prolongation of medication time,MAP,CVP,ScvO2,and Pcv-aCO2 of the two groups were increased gradually,and HR and Lac were decreased gradually (P < 0.05 or P < 0.01 compared with those before treatment) . Compared to the control group at the same time period, the treatment group had higher MAP, ScvO2, Pcv-aCO2 and PaO2/FiO2, and had lower HR, Lac, APACHEⅡ scores and SOFA scores 7 days after treatment, the difference being significant(P < 0.05).
