Efficacy and safety of sunitinib in the treatment of metastatic renal cell carcinoma.
The tyrosine kinase inhibitors (TKIs) sunitinib, the first targeted agent for the first line treatment of metastatic renal cell carcinoma (RCC), targets the vascular endothelial growth factor (VEGF) pathway. The objective of this study was to investigate the efficacy and safety of sunitinib in treating metastatic clear-cell RCC and to confirm if hypertension is an effective predictive factor. ⋯ The results of this study demonstrate the efficacy and manageable adverse event profile of sunitinib as a single agent in first- or second-line therapy for patients with metastatic clear cell RCC. Further, sunitinib-associated hypertension may be a strong predictive marker for treatment efficacy in metastatic RCC.

Multicenter StudyDeterminants for inadequate glycaemic control in Chinese patients with mild-to-moderate type 2 diabetes on oral antidiabetic drugs alone.
Prevalence of inadequate glycaemic control among patients with type 2 diabetes mellitus (T2DM) remains high. We assessed glycaemic control in the real-life practice among people with T2DM in metropolises in China who were treated with oral antidiabetic drugs (OAD) alone and to determine factors associated with inadequate glycaemic control in this population. ⋯ Approximately one half of these outpatients with T2DM from the metropolitan medical centers in China had inadequate glycaemic control treated with OAD alone, which raises the need for more effective educational and therapeutic approaches on management of hypertriglycemia, enhancing physical exercise and weight control, and at the same time, lowering the hypoglycemic risk and diminishing the hypoglycemic fear of patients.

Multicenter StudyCytogenetic characteristics of B cell chronic lymphocytic leukemia in 275 Chinese patients by fluorescence in situ hybridization: a multicenter study.
Under conventional cytogenetic (CC) analysis, only 30% - 50% of B cell chronic lymphocytic leukemia (B-CLL) cases show clonal aberrations. Using fluorescence in situ hybridization (FISH), the percentage of patients with abnormalities rises to almost 80%, among them, the most frequent abnormalities were 13q14, 11q22, p53 deletions and trisomy 12. The aim of this study was to explore the incidence of cytogenetic changes in Chinese patients with B-CLL. ⋯ Chinese CLL patients have the similar frequencies of del(13q), trisomy 12, del(11q) and a higher frequency of del(17p) when compared to literatures. Del(17p) is associated with advanced stage and low levels of Hb and PLT. Patients with p53 deletion, or advanced stage probably have poor survival in China.

Value of P16 expression in the triage of liquid-based cervical cytology with atypical squamous cells of undetermined significance and low-grade squamous intraepithelial lesions.
The management of atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesions (ASCUS/LSIL) is still controversial and it is advisable to make a triage for these two cytological abnormalities. P16(INK4) (P16) has been shown to be a potential biomarker for predicting high-grade cervical intraepithelial neoplasia (CIN) and cervical cancer. The aim of the study was to determine the value of P16 expression by immunostaining method compared with high-risk human papillomavirus (HR-HPV) DNA test in the triage of ASCUS/LSIL women. ⋯ P16 immunostaining had significantly higher specificity and accuracy than HR-HPV DNA test for predicting for high-grade CIN and cervical cancer in ASCUS and LSIL and can be used for the triage of women with ASCUS/LSIL cytological abnormality.

Case ReportsPhenylketonuria in Hong Kong Chinese: a call for hyperphenylalaninemia newborn screening in the Special Administrative Region, China.
Hyperphenylalaninemia is one of the commonest inborn errors of metabolism affecting approximately 1 in 15,000 livebirths. Among Chinese, BH4 deficiency leading to hyperphenylalaninemia is much commoner than in Caucasians. Exact diagnosis is important for the treatment and genetic counseling. ⋯ Furthermore, there is a general lack of awareness of inherited metabolic diseases in the community as well as among the medical professionals. Very often, a low index of clinical suspicion will lead to delay in diagnosis, multiple unnecessary and costly investigations, prolonged morbidity and anxiety to the family affected. We strongly recommend that expanded newborn screening for hyperphenylalaninemia should be implemented for every baby born in the Hong Kong Special Administrative Region, China.
