Chinese herbal medicine is commonly used as a treatment for benign prostatic hyperplasia （BPH）, but its efficacy and safety remain to be examined. To compare the efficacy and adverse events of Chinese herbal medicine alone or used adjuvantly with Western medications for BPH. Two independent reviewers searched the major electronic databases for randomized controlled trials comparing Chinese herbal medicine, either in single or adjuvant use with Western medication, with placebo or Western medication. Relevant journals and grey literature were also hand-searched. The outcome measures included changes in urological symptoms, urodynamic measures, prostate volume and adverse events. The frequency of commonly used herbs was also identified. Out of 13 922 identified citations of publications, 31 studies were included. Eleven studies with a Jadad score i〉 3 were selected for meta-analysis. Chinese herbal medicine was superior to Western medication in improving quality of life and reducing prostate volume. The frequency of adverse events in Chinese herbal medicine was similar to that of placebo and less than that of Western medication. The evidence is too weak to support the efficacy of Chinese herbal medicine for BPH due to the poor methodological quality and small number of trials included. The commonly used herbs identified here should provide insights for future clinical practice and research. Larger randomized controlled trials of better quality are needed to truly evaluate the efficacy of Chinese herbal medicine.

Type 2 diabetes （T2D） is associated with systemic abnormal bone remodeling and bone loss. Meanwhile, abnormal subchondral bone remodeling induces cartilage degradation, resulting in osteoarthritis （OA）. Accordingly, we investigated alterations in subchondral bone remodeling, microstructure and strength in knees from T2D patients and their association with cartilage degradation. Tibial plateaus were collected from knee OA patients undergoing total knee arthroplasty and divided into non-diabetic （n---70） and diabetes （n = 51） groups. Tibial plateaus were also collected from cadaver donors （n = 20） and used as controls. Subchondral bone microstructure was assessed using micro-computed tomography. Bone strength was evaluated by micro-finite-element analysis. Cartilage degradation was estimated using histology. The expression of tartrate-resistant acidic phosphatase （TRAP）, osterix, and osteocalcin were calculated using immunohistochemistry. Osteoarthritis Research Society International （OARSI） scores of lateral tibial plateau did not differ between non-diabetic and diabetes groups, while higher OARSI scores on medial side were detected in diabetes group. Lower bone volume fraction and trabecular number and higher structure model index were found on both sides in diabetes group. These microstructural alterations translated into lower elastic modulus in diabetes group. Moreover, diabetes group had a larger number of TRAP~ osteoclasts and lower number of Osterix~ osteoprogenitors and Osteocalcin~ osteoblasts. T2D knees are characterized by abnormal subchondral bone remodeling and microstructural and mechanical impairments, which were associated with exacerbated cartilage degradation. In regions with intact cartilage the underlying bone still had abnormal remodeling in diabetes group, suggesting that abnormal bone remodeling may contribute to the early pathogenesis of T2D-associated knee OA.

AIM： To investigate the prevalence and clinical pattern of gastrointestinal stromal tumors （GISTs） in Hong Kong Chinese, and to assess the impact of introduction of CD117 on the disease incidence. METHODS： From the database of the Department of Pathology of Yan Chai Hospital, 47 patients, with GISTs from September 1995 to December 2003 were included in this study. Ten GISTs were diagnosed before the introduction of CD117. The clinical features, tumor characteristics, and treatment were analyzed. Factors predicting tumor related death or recurrence were studied with Cox proportional hazard model. RESULTS： The patients included 26 males and 21 females, with a mean age of 66.6 years （SD 13.1, range 29-87 years）. The estimated prevalence of GISTs was 13.4-15.6 per 100 000 people, with an annual inddence of 1.68-1.96 per 100 000 people. The annual incidence of GISTs before and after the introduction of CD117 was 1.1 per 100 000 people and 2.1 per 100 000 people respectively. Stomach （34 patients, 72.3%） was the most common location for the tumor, followed by the small intestine （8 patients, 17.0%）, esophagus （2 patients, 4.3%）, omentum （2 patients, 4.3%） and colon （1 patient, 2.1%）. Thirty-one patients （66%） had complete tumor resection. Eleven out of 16 deaths （23%） were tumor-related. The median survival time was 26 too. Five-year survival rate was 61.3%. The significant factors associated with tumor-related death or recurrence were incomplete resection, tumor size 5 cm or above, invasion to the adjacent organ or presence of metastasis, CONCLUSION： The incidence of GIST in Hong Kong is comparable to that in the United States but lower than that in Finland. The true incidence of GISTs could be underestimated before the introduction of CD117. Incomplete resection, tumor size 5 cm or above, invasion to the adjacent organ or presence of metastasis are factors predicting tumor-related death or recurrence.

Objective： To further investigate the in vitro effects of an osteoprotective herbal formula ＂ELP＂（Herba Epimedii, Fructus Ligustri Lucidi and Fructus Psora/eae） using seropharmacological approach. Methods： Rats were fed with ELP or its individual component herbs for 2 days. The serum containing the post-absorbed ingredients of the herbal items were collected for cell culture using UMR106 cell, RAW264.7 cell and mesenchymal stem cell （MSC） isolated from the bone marrow of the rats. The effects of the herbal-containing serum on cell toxicity were detected by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay; bromodeoxyuridine assay was conducted to measure the cell proliferation of UMR106 cell and MSC; cell activity was measured using colorimetric method, and mRNA expression of runt-related transcription factor 2 （Runx2）, alkaline phosphatase （ALP） and osteopontin （OPN） of UMR106 and MSC as well as matrix metalloproteinase 9 （MMP-9）, tartrate-resistant acid phosphatase （TRAP） and cathepsin K of RAW264.7 were analyzed using real-time reverse-transcription polymerase chain reaction. Results： ELP and its component serum exhibited no cytotoxic effects on the cells. The ELP-containing serum increased the proliferation of UMR106 cell and MSC by 25.7% and 14.4%, respectively and the alkaline phosphatase activity of MSC was increased by 42.6%. On the contrary, it inhibited the RAW264.7 cell differentiation by 29.2%. ELP serum upregulated the Runx2 expression of UMR and MSC by 1.18 fold and 1.27 fold, respectively. It also upregulated ALP and OPN expression in MSC by 1.69- and 2.12-fold, respectively. On the other hand, ELP serum down-regulated MMP-9 and cathepsin K expression of RAW264.7 cell by 0.46- and 0.36-fold, respectively. Conclusions： The serum of the animals fed with ELP contains active ingredients which are effective in promoting osteogenesis and inhibiting osteoclastogenesis.
