· AIM: To summarize the clinical features of Chinese primary congenital glaucoma and to investigate the discrepancies of the clinical features between the Chinese and Indian patients.congenital glaucoma patients were reviewed. The clinical features were summarized as several quantifiable clinical parameters and the severity of the disease was evaluated. Both the quantified clinical features and severity were statistically compared with those of the Indian patients, which were cited from the previous published articles.included in the study. In Chinese patients, sex ratio (male to female )was about 2:1, family history was presented in 3 patients (7.5%) and consanguinity was found in one patient (2.5%). The main symptoms and signs observed in Chinese patients spanned a wide spectrum of manifestations. The most frequent signs noted on the initial examination were enlarged eyeball (42.5%) and decreased visual acuity (35.0%). Compared with Indian patients, Chinese patients had a later onset, a delayed diagnosis, more severe corneal changes and more severe optic nerve damages (P＜0.01). The combined tabeculectomy and trabeculotomy operation was preferred by both Chinese and Indian doctors whereas a higher proportion of Indian patients received the combined operation (P＜0.01). The proportions of the severity grade were different between Chinese and Indian patients. Most Chinese patients were in the severe grade while most Indian patients were in the very severe grade (P＜0.01).patients were sporadic and non-consanguineous.Compared with Indian patients, Chinese patients had a relative later onset, a delayed diagnosis and treatment.More attempts are needed in Chinese PCG prevention and treatment.

OBJECTIVETo study the distribution laws of Chinese medicine syndromes in patients with chronic heart failure (CHF) by clinical epidemiologic investigation.

METHODS512 CHF patients were studied, including 168 items of symptoms and 48 items of tongue and pulse pictures. A database of Chinese medicine syndromes was established, and 9 disease nature elements and 5 disease location elements were extracted. Frequency analysis was performed on all symptoms, tongue and pulse pictures. The variables with frequency constituent ratio less than 10.0% were deleted. Then the features of clinical epidemiology, syndrome patterns, syndrome elements, main symptoms, as well as tongue and pulse pictures were analyzed.

RESULTS(1) The disease nature elements of CHF covered qi deficiency, yin deficiency, and yang deficiency (categorized as the essential deficiency), as well as blood stasis, turbid phlegm, and the retained fluid (categorized to the superficiality excess). Among them, frequencies of qi deficiency and blood stasis (both more than 85.0%) were the highest. The disease location elements of CHF were ordered in frequency as Xin (97.9%), Pi (88.1%), followed by Shen (43.0%), Fei (30. 1%), and Gan (7.0%). (2) In the distribution of syndrome patterns in CHF patients, qi deficiency phlegm-stasis syndrome was the most (59.2%), followed by qi-yin deficiency with phlegm-stasis intermingle syndrome (20.3%), Xin-yang decline with phlegm-stasis obstruction syndrome (7.0%), and yang-deficiency with water overflowing syndrome (5.5%). (3) Patients with heart function grade II, III, and IV mainly manifested as qi-deficiency with phlegm-stasis syndrome. Besides, qi-yin deficiency with phlegm-stasis intermingle syndrome could be often seen in those with grade III. And Xin-yang decline with phlegm-stasis obstruction syndrome and yang-deficiency with water overflowing syndrome could often be seen in those with grade IV.

CONCLUSIONSThe pathogenesis of CHF is essential deficiency and superficiality excess. The essentiality consists of qi deficiency, yin deficiency, and yang deficiency, and the superficiality consists of blood stasis, turbid phlegm, and retained fluid. The disease was located at the five zang-organs, mainly dominated at Xin and Pi, and associated with Fei, Shen, and Gan. Qi deficiency phlegm-stasis syndrome was dominated in Chinese medicine syndrome patterns. Along with the aggravation of CHF, Chinese medicine syndrome pattern shows certain development laws.

Objective To evaluate the efficacy and safety of sunitinib as post-operative adjuvant therapy in patients with high-risk renal cell carcinoma (RCC).Methods A total of 60 patients with resected,histologically confirmed clear cell RCC were enrolled in this study.Patients received orally sunitinib either at a dose of 50 mg on treatment schedule (once daily for 4 weeks followed by 2 weeks off) or at a dose of 37.5 mg once daily for three 6-week cycles from 1 month after surgery.Results All the 60 patients tolerated Sunitinib treatment well and no patient discontinued treatment due to adverse events.Most adverse events were grade Ⅰ to Ⅱ.The most frequently reported adverse events were neutropenia (56.7％),thrombocytopenia (53.3％),leucopenia (48.3％),hand-foot syndrome (46.7％) and hypertension (36.7％).The most frequently reported grade 3 or 4 toxicities were thrombocytopenia (25.0％),neutropenia (15.0％),hand-foot syndrome (11.7％) and leucopenia (8.3％).The majority of adverse events occurred within the first 1-2 cycles of sunitinib treatment,and was ameliorated 1 month after 3 cycles finished.No irreversible adverse event was observed.As of April 5,2012,no recurrence occurred in patients except one death due to cerebrovascular accident unrelated to treatment,with both 6-month and 9-month disease-free survival rate of 100％.Conclusions Myelosuppression occurred less frequently in high-risk RCC patients treated with sunitinib as operative adjuvant therapy than in advanced RCC patients,with a better benefit trend.However,long-term follow-up data are needed to further confirm the efficacy of sunitinib in the adjuvant setting.

BACKGROUNDDiabetic wound is one of the most serious complications of diabetes mellitus. There are no significantly effective therapies for chronic non-healing diabetes ulcer so far. This study aimed to explore the feasibility of healing impaired wound using artificial dermis constructed with human adipose derived stem cells (ASCs) and poly (L-glutamic acid)/chitosan (PLGA/CS) scaffold in streptozotocin-induced diabetic mice.

METHODSASCs were isolated from fresh human lipoaspirates and expanded ex vivo for three passages, and then cells were seeded onto PLGA/CS scaffold to form artificial dermis. Expression of VEGF and TGFβ1 by ASCs presented in artificial dermis was determined. The artificial dermis was transplanted to treat the 20 mm × 20 mm full-thickness cutaneous wound created on the back of diabetic mice. Wound treated with scaffold alone and without treatment, and wound in normal non-diabetic mice served as control.

RESULTSCells growing within scaffold showed great proliferation potential, depositing abundant collagen matrix. Meanwhile, expression of VEGF and TGF-β1 by seeded ASCs maintained at a consistent high level. After treated with ASC based artificial dermis, diabetic wounds exhibited significantly higher healing rate compared with wounds treated with scaffold alone or without treatment. Histological examination also demonstrated an improvement in cutaneous restoration with matrix deposition and organization. Further quantitative analysis showed that there was a significant increase in dermis thickness and collagen content on artificial dermis treated wounds.

CONCLUSIONASC/PLGA artificial dermis can effectively accelerate diabetic wound healing by promoting angiogenic growth factors and dermal collagen synthesis.
