At present,there is not a clear guideline for residual solvents in the new drugs in our country. In practice,the ICH Q3C is our important reference in general,but in practical research and evaluation of new drugs,some adjustment should be made on principles of ICH Q3C,making it suitable for the reality of the pharmaceutical industry in our country. In this article, we put forward some suggestions to improve the quality control of residual solvents in our country,and some initial ideas were provided to solve the question in practice.

Objective To study the feasibility,safety,and efficacy of hysteroscopic treatment of submucous leiomyomas and endometrial polyps.Methods Hysteroscopic resections were performed in 38 cases of submucous leiomyomas and 40 cases of endometrial polyps from January 2002 to July 2004,including 31 cases of transcervical resection of myoma(TCRM),7 cases of TCRM combined with transcervical resection of the endometrium(TCRE), 35 cases of transcervical resection of polyp(TCRP),and 5 cases of TCRP combined with TCRE.Results The operation was completed smoothly on one session in all the 78 cases.The intraoperative blood loss was ≥ 400 ml in 2 cases.There were 1 case of overhydration.No uterine perforation or infection occurred after operation.The patients were followed at 1,3,6,and 12 months after operation,respectively,and the surgical outcomes were assessed at 12 postoperative months.Follow-up findings revealed 8 cases of amenorrhea(10.3%),12 cases of irregular spotting(15.4%),33 cases of hypomenorrhea(42.3%),22 cases of normal menstrual flow(28.2%),and 3 cases of no improvement(3.8%).Conclusions Hysteroscopic resections for submucous leiomyomas and endometrial polyps offer advantages of good reliability and fewer complications,being worthy of recommendation.

Objective To investigate the mechanism of insulin resistance (IR) with coronary heart disease (CHD) by the relationship study between IR and the risk factors of CHD as well as the severity of coronary lesions. Methods One hundred and twenty three patients with at least one vessel ≥50% luminal narrowing were analyzed from our consecutive angiographic data base, excluding patients concomitant with hepatic, renal, pancreatic diseases, thyroid disorders and diabetes mellitus (DM) with insulin therapy. Oral glucose tolerance test (OGTT), blood lipid, plasma insulin were performed in all patients. Insulin resistance was assessed by homeostasis model assessment (HOMA) to investigate the relationship study between insulin resistance and the risk factors of CHD,severity of coronary lesions as well as the clustering of risk factors (hypertension, overweight, impaired glucose tolerance/DM, high serum triglycerides, low high density lipoprotein cholesterol). Results The level of IR was correlated with the levels of body mass index (BMI), fasting glucose, postprandial glucose, fasting insulin, postprandial insulin, hypertension, serum triglycerides, and high density lipoprotein cholesterol. Meanwhile the level of IR was associated with clustering of risk factors and the extent and the severity of coronary lesions. Conclusion Insulin resistance may be the basis for disease. In the primary and secondary prevention of CHD, we should not only treat syndromes but also reduce the level of IR.

Objective To determine the relationship between subclinical hypothyroidism and asymptomatic myocardial ischemia in type 2 diabetes mellitus.Methods All of 399 asymptomatic subjects who underwent coronary CT angiography with type 2 diabetes mellitus but without thyroid disease were enrolled retrospectively.Totally patients were divided into subclinical hypothyroidism group (17 patients,type 2 diabetes mellitus with subclinical hypothyroidism) and euthyroid group(382 patients,type 2 diabetes mellitus with normal thyroid function).Results The incidence of subclinical hypothyroidism in type 2 diabetes mellitus was 4.3％(17/399).The ratio of male and smoking in subclinical hypothyroidism group was significantly lower than that in euthyroid group (3/17 vs.194/382,P =0.007;2/17 vs.136/382,P =0.043).The incidence of asymptomatic myocardial ischemia in subclinical hypothyroidism group was 5 cases and in euthyroid group was 130 cases,and there was no significant difference(P=0.694).The age,course of type 2 diabetes mellitus,level of glycosylated hemoglobin and low density lipoprotein cholesterol between two groups had no significant difference(P＞ 0.05).Conclusion Subclinical hypothyroidism is not an independent risk factor for asymptomatic myocardial ischemia in type 2 diabetes mellitus.

Objective To study the influence of early intensive blood pressure (BP) lowering treatment on peri-he?matomal secondary neuronal injury and prognosis after acute intracerebral hemorrhage. Methods A randomised con?trolled trial consisting of 36 consecutive patients within 6 h of intracerebral hemorrhage onset were randomly assigned to intensive BP lowering group and guideline BP lowering group. All patients underwent MR spectroscopy at 72 h and were followed up 90 days. N Acetyl Aspartate/Creatine (NAA/Cr) and lactic acid wave around peri-hematomal at 72 h, neuro?logic function at early stage, and death and/or disability at 90d were compared between these two group. Results Spec?trum lines were obtained from thirty-one patients:14 from intensive BP lowing group and 17 from guideline BP lowering group. There was no significant difference in the percentage declines of NAA/Cr at 72 h between the two groups (13.3%± 4.2% vs. 11.9%± 2.8%, P = 0.308). There was no statistical differences either in neurologic function at 7 d or in death and/or disability at 90 d (P>0.05). Conclusions Early intensive BP-lowering treatment had no role on peri-hematomal secondary neuronal injury and prognosis after acute intracerebral hemorrhage. Further high-quality and large-scale ran?domised controlled trial are necessary to verify this result.

Objective To investigate association of pancreatic fat content and lipid levels in individuals with newly diagnosed type 2 diabetes.Methods Fifty four subjects with newly diagnosed type 2 diabetes and 22 volunteers without type 2 diabetes were enrolled in this study.Pancreatic fat content was determined with magnetic resonance imaging.Lipid levels were measured.Results The pancreatic fat content in patients with newly diagnosed type 2 diabetes and control subjects was (17.13 ± 10.35) ％ and (11.62 ±7.15)％, respectively (P =0.025).Median pancreatic fat content of subjects with newly diagnosed type 2 diabetes correlated negatively with total cholesterol level (r =-0.361, P =0.007) and triglycerides level (r =-0.346, P =0.010).Conclusions Increased levels of serum total cholesterol and low density lipoprotein cholesterol might relieve the extent of pancreatic fat content.

Objective To investigate the immunogenicity and cross protective effects of two novel HCV DNA vaccines in a mice model.Methods Two self-replicating alphavirus vector-based HCV DNA vaccines, pSCK CE1E2Y and pSCK H155, were constructed based on the genes encoding the structural pro-teins (Core, E1 and E2) and structural and NS3 fusion proteins (Core, E1 , E2 and NS3) of a HCV strain isolated from a Chinese patient (genotype 1b, Hebei strain), respectively.Western blot analysis was per-formed to detect the expression of fusion antigens.The BALB/c mice were intradermally immunized with the recombinant DNA vaccines by using electroporation.The immune responses induced in mice and the cross protective effects of the recombinant DNA vaccines were evaluated.Results The DNA vaccines effectively expressed the target antigens in vitro.The antigen-specific antibody responses and specific T cell immune re-sponses were induced in mice by the immunization of replicative DNA vaccines.However, no effective cross protection was provided by either of the DNA vaccines in the surrogate challenge model based on a recombi-nant heterologous HCV (JFH1, 2a) vaccinia virus strain.Conclusion Although no effective cross protec-tion was observed, both of the two replicative DNA vaccines could induce strong humoral and cellular im-mune responses against multi-target antigens of HCV strains.This study has paved the way for further inves-tigation on the development of novel HCV vaccines.

Objective To determine the relationship between subclinical hypothyroidism (SCH) and the prevalence of albuminuria in type 2 diabetes mellitus.Methods A total of 826 type 2 diabetes mellitus patients without thyroid disease were enrolled.Participants were evaluated for glycemic control,thyroid function,and albuminuria in a cross-sectional analysis.Results Of 826 type 2 diabetes mellitus,780 subjects were euthyroid(94.44％,780/826) and 46 had SCH (5.56％,46/826).The patients with SCH had a higher proportion in women and higher body mass index compared with the patients with euthyroid [69.6％(32/46) vs.49.7％(388/780),(26.7 ± 4.0) kg/m2 vs.(25.1 ± 3.8) kg/m2],and there was significant difference(P ＜ 0.01).No significant difference in glycated hemoglobin and the prevalence of albuminuria was found between the patients with SCH and the patients with euthyroid (P ＞ 0.05).Conclusion SCH is not a risk factor for albuminuria in type 2 diabetes mellitus.
