OBJECTIVETo explore the effect of combination of Epimedii Folium and Ligustri Lucidi Fructus on osteoporosis rats induced by retinoic acid.

METHODSixty three-month-old male Wistar rats were randomly divided into the normal control group, the model group, the Epimedii Folium group, the Ligustri Lucidi Fructus group, the combination group of Epimedii Folium and Ligustri Lucidi Fructus and the raloxifene group. The osteoporosis model was established through oral administration with retinoic acid for two weeks. Meanwhile, all of treatment groups were administered with corresponding drugs for three weeks. The contents of serum calcium (Ca), phosphorus (P), alkaline phosphatase (AKP) and tartrate-resistant acid phosphatase (StrACP) were detected, and the pathomorphological changes of femurs were observed.

RESULTThe model control group showed much lower contents of serum Ca and P than the normal control group, but with significantly higher AKP and StrACP activity than the normal control group. The femoral head area showed reduced, narrow and sparse trabecular bones, with typical osteoporosis-like changes. Compared with the model control group, all of treated groups showed significant increase in Ca and P contents in serum, and down-regulate AKP and StrACP levels, while trabecular bones became more and wider, and densely interweaved as a reticular formation. Among them, the combination group showed the most significant effect.

CONCLUSIONEpimedii Folium and Ligustri Lucidi Fructus could effectively correct the abnormal bone metabolism and improve pathological conditions of bone tissues, so as to show the anti-osteoporosis effect. The combined application of the two drugs showed a better efficacy.

Objective : To evaluate the effectiveness of interventions for human papillomavirus ( HPV ) vaccine hesitancy among female university students based on the precaution adoption process model (PAPM), so as to provide the evidence for improving the coverage of HPV vaccine in this population. Methods : HPV vaccine hesitant female students were selected using a cluster sampling method from Zhejiang Chinese Medical University, and randomly assigned to the PAPM group and control group. Students in the PAPM group received PAPM-based interventions for HPV vaccine hesitancy, while students in the control group were given routine interventions. The HPV-related knowledge, HPV vaccine-related knowledge and HPV vaccine hesitancy scores were collected from both groups prior to interventions ( T0 ), 0 ( T1 ), 1 ( T2 ) and 3 months post-interventions ( T3 ), and the effectiveness of interventions was evaluated using analysis of variance for repeated measures. Results : There were 147 students in the PAPM group and 141 students in the control group. In the PAPM group, 36.73% of the students majored in medical sciences, and 48.23% were freshmen; in the control group, 39.72% majored in medical sciences, and 50.35% were freshmen. The mean scores of HPV- and HPV vaccine-related knowledge were significantly greater in the PAPM group than in the control group, respectively ( T1, 5.29 vs. 4.91; T2, 4.27 vs. 4.22; T3, 4.22 vs. 4.04; P<0.05 ); however, no significant differences were detected in the HPV vaccine hesitancy scores between the two groups, respectively ( T1, 2.98 vs. 2.95; T2, 3.07 vs. 3.07; T3, 3.08 vs. 2.97; P>0.05 ). The mean scores of the confidence dimension ( T1, 3.37 vs. 3.23; T2, 3.48 vs. 3.40; T3, 3.38 vs. 3.25 ) and the dimension of influence by others ( T1, 3.44 vs. 3.33; T2, 3.42 vs. 3.37; T3, 3.46 vs. 3.27 ) were significantly greater in the PAPM group than in the control group (P<0.05), while the mean scores of the complacency dimension were significantly lower in the PAPM group than in the control group ( T1, 1.98 vs. 2.03; T2, 2.06 vs. 2.20; T3, 2.18 vs. 2.15; P<0.05 ). Conclusions PAPM-based interventions for HPV vaccine hesitancy may effectively improve the awareness of HPV and HPV vaccines, reduce complacency, and enhance the influence by others among female university students.

The dynamic of endophytic bacteria at different growth stage of tomato and use of these endophytic bacteria to control tomato bacterial wilt were studied. The results showed that endophytic bacteria could be found in the tomato seeds and their quantities reached the highest peak in the adult plants both in resistant and susceptible cultivars. The amount of endophytic bacteria in adult plants of resistant tomato cultivars was 2.43?10~5CFU/g FW in the root and 22.9?10~4 CFU/g FW in the stem, while the amount of endophytic bacteria in adult plants of susceptible tomato cultivars was 9.8?10~4CFU/g FW in the root and 13.4?10~4CFU/g FW in the stem respectively. Seventeen strains of endophytic bacteria from resistant cultivars and only seven strains from susceptible cultivars were found to be antagonistic to Ralstonia solanacearum. In addition, some strains of endophytic bacteria had the abilities of promoting tomato seed germination and controlling tomato bacterial wilt, among which, strain 5R and 3R had better control effect of 91.7% and 81.3% respectively.

Forty type 2 diabetic patients with diabetic peripheral neuropathy (DPN) were assigned to two groups and treated respectively with?-lipoic acid or mecobalamin for 2 weeks.The results suggested that?-lipoic acid could accelerate the nerve conduction velocity and decrease the plasma level of endothelin and C reactive protein as well as microalbuminceria with a effect similar to mecobalamin therapy on DPN.

Ribavirin is a broad-spectrum antiviral agent and glycyrrhizin has activities of anti-inflammation, immunoregulation and anti-viral infections. To enhance antiviral efficacy and weaken side-effects of ribavirin, antiviral effects of the combination of glycyrrhizin and ribavirin were studied in the present study. Firstly, a mouse model of viral pneumonia was established by inoculation of influenza H1N1 virus. Protective effects of glycyrrhizin and ribavirin used alone or in combination against H1N1 virus infection in mice were evaluated based on the survival rate, lung index and virus titer in lungs of mice. Results showed that the combination of glycyrrhizin and ribavirin significantly inhibited the lung consolidation with a 36% inhibition ratio on the lung swell of infected mice. The combination of the two drugs exhibited synergetic effects on survival of infected mice. The combination of 50 mg · kg(-1) · d(-1) glycyrrhizin and 40 mg · kg(-1) · d(-1) ribavirin resulted a 100% protection for infected mice with a synergetic value of 36, which was significantly higher than the control group and each drug alone. This combination also resulted a significant drop of lung virus titer (P < 0.01), as well as inhibition on the production of proinflammatory cytokines IL-6 (P < 0.01), TNF-α (P < 0.01) and IL-1β (P < 0.05) induced by virus infection compared to the control. The treatment of ribavirin plus glycyrrhizin was more effective in influenza A infection in mice than either compound used alone, which suggested a potential clinical value of the combination of the two agents.

OBJECTIVETo observe the differences of therapeutic effect in primary trigeminal neuralgia (PTN) of hyperactive of liver yang type treated by deep and shallow puncturing at Xiaguan (ST 7).

METHODSSixty-three cases of PTN of hyperactive of liver yang type were randomly divided into a deep puncturing group (32 cases) and a shallow puncturing group (31 cases). Xiaguan (ST 7) of affected region, Hegu (LI 4) and Taichong (LV 3) of bilateral sides, Cuanzhu (BL 2), Sibai (ST 2) and Jiachengjiang (Extra) relevant to the affected branch of nerve stem were selected in both groups. In deep puncturing group, Xiaguan (ST 7) was punctured to the depth of spheno-palatine ganglion (SPG); Cuanzhu (BL 2), Sibai (ST 2) and Jiachengjiang (Extra) were respectively punctured to the depth of supraorbital foramen, infraorbital foramen and mental foramen. In shallow group, routine puncturing was applied; the needles were connected with G6805 electric acupuncture apparatus, and switched on for 30 min every time; the treatment was applied every other day. Pain index, traditional Chinese medicine symptoms index and clinical therapeutic effect were observed after 2 courses of treatment.

RESULTSIn deep puncturing group, the VAS scores and the traditional Chinese medicine symptoms scores (pain degree, pain frequency, upsetting, conjunctival congestion, bitter mouth and hypochondriac pain) after treatment were much more lower than those before treatment (all P < 0.01); in shallow puncturing group, except hypochondriac pain (P > 0.05), other indices above after treatment were obviously lower than those before treatment (P < 0.01, P < 0.05). Compared with the indices in both groups after treatment, the VAS scores, the pain degree, conjunctival congestion and total scores of traditional Chinese medicine symptoms in deep puncturing group were more significant (all P < 0.05). The total effective rate was 93.8% (30/32) in deep puncturing group, superior to that of 87.1% (27/31) in shallow puncturing group (P < 0.05). No any adverse reaction was observed in both groups.

CONCLUSIONThe therapeutic effect of trigeminal neuralgia of hyperactive of liver yang type treated with electroacupuncture is remarkable, and deep puncturing at Xiaguan(ST 7) to SPG is more effective than routine puncturing.
