Purpose: Recent studies in several tumors showed that presence of cancer stem like side population (SP) cells are responsible for chemotherapeutic drugs resistance and tumor relapse. In our present study, we have analyzed the role of SP cells in oral squamous cell carcinoma cell (OSCC) line OSCC-77.

Methods: The oral cancer cell line OSCC-77 was analyzed for the presence of SP cells by FACS using Hoechst 33342 dye exclusion method.

Background And Aims: Roux-en-Y gastric bypass (RYGB) is effective in controlling blood glucose in obese patients with type 2 diabetes (T2DM). The alterations of gut hormones involving in glucose metabolism may play an important role. Our aim was to explore the short-term effects of Billroth II gastrojejunostomy (a similar type of RYGB) on glucose metabolism and gut hormone modulations in nonobese patients with different levels of blood glucose tolerance.

Objective: To search for new potential diabetogenic mtDNA defects by scanning mtDNA genome in mitochondrial DNA diabetes (MDM) pedigrees.

Methods: Blood samples were collected from the family members in two suspected MDM pedigrees, which were both maternal transmitted and early-onset diabetes. The whole mtDNA genome except D-loop was detected by direct sequencing in probands of these two diabetic pedigrees.

Objective: To evaluate the therapeutic effects of bone marrow transplantation (BMT) on ovarian injury induced by chemotherapy in mice.

Methods: Forty-eight mice were randomized equally into normal control group (A), cyclophosphamide and BMT group (B), and cyclophosphamide group (C). The mice in groups B and C were treated with intraperitoneal injection of cyclophosphamide at the daily dose of 150 mg/kg for 3 consecutive days, and allogeneic bone marrow cell transplantation was performed in group B.

Objective: To investigate the prevalence of diabetes and prediabetes mellitus in the first-degree relatives (FDR) of patients with type 2 diabetes (T2DM) in Chengdu.

Methods: A cross-sectional study was undertaken in Chengdu. A total of 2306 adults were recruited, including 535 FDR of T2DM patients and 1771 people without a family history of diabetes.

Objective: A multicenter, randomized, controlled and open-labeled clinical trial was performed to compare the efficacy and safety of recombinant human insulin injection (Yousilin R) and Novolin R in diabetic patients.

Methods: A total of 211 cases were randomized into two groups (1:1) treated with Yousilin R versus Novolin R for 12 weeks respectively.

Results: Compared with baseline, the levels of glycosylated hemoglobin A1c (HbA1c) at the end of 12 weeks treatment decreased from 10.

Objective: To examine the association of the Thr394Thr polymorphism of PPARGC1A gene with type 2 diabetes (T2DM), insulin resistance (IR) and other metabolic disorders in a Chinese population.

Methods: Three hundred and seven subjects including 151 T2DM patients and 156 normal glucose tolerant controls (NC) were enrolled in this study. The Thr394Thr G/A polymorphism was genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

Article Synopsis
  • - The study aimed to assess how common metabolic syndrome (MS) is among adults in Chengdu, surveying over 2,200 residents aged 20 and older using specific diagnostic criteria.
  • - Results indicated that 17.2% of adults had MS, with significant differences between males (15.0%) and females (18.6%), and several components of MS showed notable prevalence rates, including central obesity and hypertension.
  • - The findings highlight important risk factors like age and hypertension, suggesting that MS is a growing issue in Chengdu that requires immediate public health interventions due to potential increases related to socio-economic development and an aging population.

Objective: To investigate the characteristics of glycemic excursions in people with normal glucose tolerance (NGT) in Chengdu.

Methods: A total of 50 non-obese people with normal glucose tolerance (NGT, 23-68 years old), normal blood pressures and lipid profiles participated in the study. The fluctuations of glucose levels in the participants were measured by a continuous glucose monitoring system (CGMS) for three days 72 h.

Article Synopsis
  • The study evaluates how tissue culture impacts the viability and development of follicles in frozen-thawed human fetal ovarian tissue before transplanting it into SCID mice.
  • A total of 20-week-old fetal ovarian tissue samples were cultured for 0, 3, 6, or 9 days, with the results showing that longer culture periods (6 or 9 days) led to more developed follicles post-transplant compared to shorter durations.
  • The findings suggest that pretransplant tissue culture can enhance follicle viability, with 6 days being the optimal duration for effective results.

Background: Autotransplantation of frozen-thawed ovarian tissue has proven to be an effective method to restore endocrine function and fertility. But it remains to be studied which site and which method is most effective and practical. We therefore implanted small pieces of cryopreserved ovarian tissues into different sites in rabbits to find the optimal position.

Objective: To study the relationship between insulin resistance and endothelium-dependent vasodilatation function in obese subjects with normal blood glucose, serum cholesterol and blood pressure and to explore the non-traditional risk factors associated with atherosclerosis.

Methods: 24 euglycemic obese males (OB) and 12 age and sex matched lean controls (Lean) underwent oral glucose tolerance test (OGTT), euglycemic hyperinsulinemia clamp study with an insulin infusion rate of 120 mU/m(2)/min to evaluate the peripheral glucose disposal rate (GDR) in steady-state, brachial artery ultrasound study to assess the endothelium-dependent vasodilation (EDV) and independent vasodilation (EIV), the combined intima-media thickness (IMT) of common carotid arteries examined by high resolution ultrasound, and fasting lipids profile and free fatty acids (FFAs) concentration.

Results: The blood glucose and serum cholesterol levels were all normal in the OB group but the serum FFA and triglyceride concentrations were elevated compared with those of the controls (FFA: 888 microM/l +/- 158 microM/l vs 508 microM/l +/- 137 microM/l, P < 0.
