OBJECTIVETo observe the expressions of human beta-defensin 1 and 2 (hBD-1 and hBD-2) in nasal mucosa before and after the endoscopic sinus surgery and investigate the effects of hBD-1 and hBD-2 on the healing process after the surgery.

METHODSThe patients undergoing endoscopic sinus surgery for chronic sinusitis were divided into 3 groups according to the response to the surgery, namely cured group, response group and non-response group. With those from healthy control subjects as the control, nasal mucosa samples were collected from the patients at 1 week, 2 weeks, 1 month, 3 months and 6 months after the surgery for detection of hBD-1 and hBD-2 mRNA and protein expressions by RT-PCR and Western blotting.

RESULTShBD-1 and hBD-2 were expressed in both normal and chronic sinusitis mucosa, but the expression levels varied significantly between the individuals. The expression levels of hBD-2 was significantly correlated to the patients' response to the surgical treatment (P<0.05). hBD-1 showed slight differences between the individuals, but was not associated with the patients' prognosis.

CONCLUSIONThe expressions of hBD-2 mRNA and protein are significantly increased in patients with good response to endoscopic sinus surgery for chronic sinusitis, suggesting the value of hBD-2 as an indicator of the patients' prognosis.

OBJECTIVETo explore the quality of life and related social support among people living with HIV/AIDS with related factors.

METHODS331 people living with HIV/AIDS and 148 of their family members were selected using a typical sampling method. Questionnaires on general conditions, tables on history of infection, generic quality of life inventory-74 (GQOLI-74) and social support scale (SSS) were used.

RESULTSData from one-way analysis suggested that people living with HIV/AIDS and their family members with the different sexs, different villages and different cultural backgrounds had differences in GQOLI-74 scores (P < 0.05) while people living with HIV/AIDS with the different villages had differences in SSS scores (P < 0.05). Results from Multiple linear regression analysis revealed that being elderly and negative life events were negatively associated with social support (P < 0.05), while factors as more advanced educational background, harmonious neighborhood relationship and having bother pouring nature were the predictive factors (P < 0.05).

CONCLUSIONMany factors might affect dimensions of quality of life among people living with HIV/AIDS and their family members in rural areas of northern Anhui. Community care and social support of HIV/AIDS should still be greatly enhanced in the countryside of China. A community care mode based on family and neighborhood was expected to be developed.

Objective To investigate the effect of recombinant human granulocyte macrophage colony stimulating factor (rhGM-CSF) as adjuvant on immune response in adults of non-and hyporesponders to hepatitis B vaccine. Methods Those who were once immunized with recombined yeast gene hepatitis B vaccine more than one standard scheme in two years and negative for hepatitis B markers were randomly sorted as group A and group B. 33 adults of group A were given hepatitis B vaccine 10 μg each time. The immune procedure was O, 1 and 6month. 34 adults of group B were given rhGM-CSF 300 μg for the first day, then 10 μg each time for routine immune. The blood samples were collected before the first injection and in 1, 2 and 8 months (T1, T2, TS)following the first injection to test Anti-HBs. Results Anti-HBs positive conversion rates of group A and B at T8 was 39.39% and 64.71% respectively(P=0.038). Anti-HBs levels of group B at TI, T2, T8 were(113.85±198.56) mIU/ml, (312.40±349.44) mIU/ml, (427.74±411. 58) mIU/ml (P=0.001). There was significant difference between group A and B in T8 Anti-HBs levels(P=0.010). Conclusion Better immune response was found in the group of rhGM-CSF with hepatitis B vaccine. So rhGM-CSF can induce the immune respond to hepatitis B vaccine.

OBJECTIVETo observe the clinical therapeutic effects on cervical spondylosis of vertebral artery type treated with both acupuncture and mild moxibustion and investigate the mechanism of action.

METHODSSixty cases were randomly divided into the combined therapy group of acupuncture and mild moxibustion (combined therapy group) and the acupuncture group, 30 cases for each group. In combined therapy group, Baihui (GV 20), Fengchi (GB 20) and cervical Jiaji (EX-B 2) were punctured, and Baihui(GV 20), Dazhui (GV 14), Mingmen (GV 4), Shenque (CV 8) and Guanyuan (CV 4) were treated with mild moxibustion; in acupuncture group, acupuncture was simply applied, the acupoints selection and manipulation were the same as those in the combined therapy group. The average velocity meter and the resistive index of vertebral and basal arteries were observed before and after treatment by TCD examination, the therapeutic effects and clinical symptom-sign scores were observed too.

RESULTSThe total effective rate was 93.3% (28/30) in combined therapy group, and 73.3% (22/30) in acupuncture group. The therapeutic effect in combined therapy group was superior to that in acupuncture group (P < 0.05). The improvements of symptom-sign scores in two groups after treatment were more significant than that before treatment, and the score in the combined therapy group was superior to that in acupuncture group (P < 0.05). The average velocity meter and the resistive index of vertebral and basal arteries after treatment were improved in both groups, in which, the improvement in combined therapy group was more apparent (all P < 0.05).

CONCLUSIONThe therapeutic effects on cervical spondylosis of vertebral artery type treated with both acupuncture and mild moxibustion are preferable; by this therapy, the average velocity meter of vertebral and basal arteries are accelerated and the resistive index is decreased.

To research the effect of Ginseng Radix et Rhizoma and Aconiti Lateralis Radix Praeparata compatibility on cardiac toxicity in rats by UPLC-Q-TOF/MS, and explore the endogenous markers and molecule mechanism. Different compatibility of Shenfu decoction were given to male Wistar rats at dosage of 20 g · kg(-1) for 7 days, collected the serum, and analyze the endogenous metabolites effected by Shenfu formulation by principal component analysis and partial least-squares analysis. Results showed that content of glutathione, phosphatidylcholine and citric acid decreased in mixed-decoction group, while ascorbic acid, uric acid, D-galactose, tryptophan, L-phenylalanine increased. The results showed cardiac toxicity of Aconiti Lateralis Radix Praeparata in Shenfu mixed-decoction. Shenfu co-decoction group showed a similar or weaker trend compared with control group, but most of them do not have a statistically significant. The results indicated the scientific basis of Shenfu compatibility by comparison of co-decoction group with mixed-decoction group. Shenfu compatibility can reduce cardiac toxicity induced by Aconiti Lateralis Radix Praeparata, and citric acid, glutathione, phosphatidyl choline, uric acid might be regarded as potential markers of cardiotoxicity.

OBJECTIVETo investigate the expression and the localization of Cathepsin K and IL-6 mRNA in root-resorbing tissue and to elucidate the molecular changes and mechanism of root resorption induced by tooth movement.

METHODSRats were subject to experimental tooth movement to induce root resorption. In situ hybridization was performed to identify the cells in root-resorbing tissue that produced Cathepsin K or IL-6 the difference of CK mRNA or IL-6 mRNA expression between root resorption group and control group was calculated by t-test.

RESULTSCathepsin K mRNA was highly and selectively expressed in multinuclear odontoclast and IL-6 mRNA expressed in fibroblast, osteoblast, osteocyte and cementoblast. The expression of Cathepsin K mRNA and IL-6 mRNA in root-resorbing tissue increased evidently compared with the normal periodontium.

CONCLUSIONSOdontoclast in the root-resorbing tissue expresses Cathepsin K mRNA that participates in proteolysis during root resorption. IL-6 plays a very important role in the root resorption as a multifunctional cytokine.
