ObjectiveTo investigate the effect of Jiuqiang Naoliqing(JNQ) on the TXA2 and PGI2 level in spontaneous hypertension rat (SHR) plasma.MethodsThe plasma was separated after the SHR and Wistar rats were treated with JNQ at the dose of 0.133g/kg,0.265g/kg,0.530g/kg and 1% carboxymethyl cellulose respectively for 5 weeks. The level of TXB2 and 6 keto PGF1α ,stable metabolin of TXA2 and PGI 2,in SHR plasma was tested by radioimmunoassay.ResultsThe level of TXB2 and the ratio of TXB2/6 keto PGF1α (T/P) in SHR plasma increased significantly(P<0.01),and there was no significant difference in the concentration of 6 keto PGF1α between Wistar rats and SHR plasma(P>0.05). JNQ could increase the generation of 6 keto PGF1α and decrease the level of TXB2 and T/P in SHR plasma after treated with different dosages for 5 weeks.ConclusionJNQ may improve the balance between TXA2 and PGI2 in SHR plasma.

Objective: To screen candidate antigen for therapeutic HBV vaccine with a novel adjuvant DC-Chol. Methods: BALB/c mice were injected with DC-Chol liposome and HBsAg prepared from CHO and Yeast respectively. One week later, IL-4, IL-2, IFN-?were measured by ELISA or ELISPOT. Results: The levels of IL-2, IFN-?of HBsAg from Yeast with DC-Chol liposome were 20 and 119 times higher respectively than those of HBsAg from CHO with DC-Chol liposome. ELISPOT assay showed that the counts of spot-forming cells of IL-4 and IFN-?of HBsAg from Yeast with DC-Chol liposome were 2.8 and 46.3 times higher respectively than those of HBsAg from Yeast with Al(OH)3. Conclusion: HBsAg prepared from Yeast together with DC-Chol liposome may be an appropriate candidate for therapeutic HBV vaccine .

Being the unique core of traditional Chinese medicine (TCM), pattern classification exerts a direct effect on the efficacy and safety of herbal interventions. In this article, the authors integrated the pattern classification and disease diagnosis with many approaches from systems biology. Integration of pattern classification with biomedical diagnosis by systems biology is not only a new direction of personalized medicine development, but also provides a new drug development model. In the further study, the pattern classifications of major diseases will be the focus of research.

OBJECTIVETo investigate the relationship between lamivudine-resistant mutants of hepatitis B virus (HBV) and serum HBV DNA loading before antiviral therapy.

METHODSThis study involved 106 patients with hepatitis B receiving lamivudine treatment for an average of 32 months (rang 12-48 months). Serum HBV DNA loadings were measured with PCR before and every 4 to 6 months during lamivudine therapy. HBV YMDD mutants were detected using mismatched PCR-restriction fragment length polymorphism (PCR-RFLP) during lamivudine treatment.

RESULTSHBV DNA loading was significantly higher in patients infected with HBV YMDD mutants during lamivudine therapy than those infected with HBV without YMDD mutation.

CONCLUSIONHigh viral loading in hepatitis B patients before treatment is associated with high likeliness of HBV YMDD mutation during lamivudine treatment. HBV DNA loading may be indicative for the occurrence of YMDD mutation during lamivudine therapy.

Hypospadias is one of the most common congenital malformations, and its main clinical manifestation is the abnormal opening of the urethra. Etiologically, it can be attributed to many factors, mainly including genetic, hormonal, and environmental factors. Recently studies about its genetic etiologies have found a variety of hypospadias-associated genes from the aspects of epidemiology and polymorphism, mainly those involving the formation of the penis, the development of the testis, the anabolism of androgens, and so on. This review focuses on the progress in the studies on the genetic etiology of hypospadias.

A new species of genus shewarella Shewanellade decolorations S12, was isolated from activated sludge of a textile-printing waste-water treatment plant. In the anaerobic condition, S12 could conserve energy for growth by using Fe3 + as the terminal electron acceptor. At the optimal condition of pH8, temperature 30℃, ferric citrate 800mg/L, sodium lactate 2g/ L, yeast extract 0. 5g/ L , the cell growth increased with the raise of the amount of the Fe3+ reduction in 8k The effect of different carbon soucres, nitrogen sources, pH values and growth temperatures on the anaerobic Fe3 + reduction of Shewanella decolorations S12 was investigated. LB was favorable for Fe3 + reduction. Glucose and sodium lactate also were favorable for Fe3+ reduction. The cell growth and Fe3 + reduction increased with the raise of the amount of the yeast extract from 0 to 4g/L The amounts of the sodium lactate of 6g/ L and ferric citrate of 800mg/L were suitable for strain S12 growth and Fe3+ reduction. In the optimum initial pH value range of 6 -8 for Fe3+ reduction, strain S12 growth increased with the raise of the pH val- ue. Strain S12 could growth and reduce Fe3+ at the temperature range of 20 -40℃. The best temperature for strain S12 growth and Fe3 + reduction was 301.

OBJECTIVE: Functional constipation (FC) is a common intestinal disease worldwide. Despite the presence of criteria such as Roman IV, there is no standardized diagnosis and treatment algorithm in Hong Kong that combines both Western and Chinese medicine approaches. This study integrates current effective and safe diagnosis and treatment methods for FC and provides a clear and scientific pathway for clinical professionals and patients. METHODS: A systematic search of the PubMed, Cochrane Library, and China National Knowledge Infrastructure databases was performed from their inception to June 30th, 2022, collecting the current evidence about the efficacious integrative management for FC. We organized a meeting of professionals in fields relevant to treatment and management of FC to develop a consensus agreement on clinical pathway process. RESULTS: We developed a clinical pathway for the treatment of FC based on the most recent published guidelines and consultation with experts. This pathway includes a hierarchy of recommendations for every step of the clinical process, including clinical intake, diagnostic examination, recommended labs, diagnostic flowchart, and guidance for selection of therapeutic drugs. CONCLUSION This pathway establishes clinical standards for the diagnosis and treatment of FC using Chinese medicine and Western medicine; it will help to provide high-quality medical services in Hong Kong for patients with FC.
