OBJECTIVETo compare the clinical efficacy of 3 different treatment programs for oligospermia patients of Shen-essence deficiency syndrome (SEDS).

METHODSTotally 450 male patients were randomly assigned to 3 groups, i.e., the treatment group, the control group 1, and the control group 2, 150 in each group. Patients in the treatment group were treated by Bushen Yijing Decoction (BYD), tamoxifen tablet (TT), Licorzine Capsule (LC), and Vitamin E Soft Capsule (VESC). Those in the control group 1 were treated by BYD, LC, and VESC. Those in the control group 2 were treated by TT, LC, and VESC. All patients were treated for 3 months. Their pregnant rates were compared. Clinical efficacies of each Chinese medical symptom and sperm parameters [sperm density, grade a sperm motility rate, grade (a + b) sperm motility rate, grade (a + b + c) sperm motility rate, and normal sperm morphology rate] were compared before and after treatment.

RESULTSAt 3 months after treatment 61 patients were pregnant in the treatment group, 36 patients were pregnant in the control group 1, and 30 patients were pregnant in the control group 2. The differences in the sperm density, grade a sperm motility rate, and grade (a + b) sperm motility rate, and grade (a + b + c) sperm motility rate between before and after treatment were significantly higher in the treatment group than in the control group 1 and the control group 2 (P < 0.01). The difference in the normal sperm morphology rate between before and after treatment was obviously higher in the treatment group and the control group 1 than in the control group 2 (P < 0.01). Better results were obtained in the treatment group and the control group 1 in improving the sexual apathy, soreness and weakness of waist and knees, impotence, premature ejaculation, seminal emission, dizziness, tinnitus, forgetfulness, alopecia, when compared with the control group 2 (P < 0.01, P < 0.05). There was no statistical difference in the total effective rate of improving Chinese medical symptoms between the treatment group and the control group 1 (P > 0.05).

CONCLUSIONBYD combined with TT, LC, and VESC could significantly improve sperm qualities and clinical Chinese medical symptoms of oligospermia patients of SEDS.

To investigate the influence of Anxin granules combined with tirofiban on acute myocardial infarction (AMI) Patients after elective percutaneous coronary intervention (PCI). One hundred and twenty AMI patients were randomly divided into treatment group and control group. The patients in the two groups were all given Tirofiban 30mins before PCI . The treatment group was added Anxin granules 30 mins before and after PCI. Tissue factor (TF) and von willebrand factor (vWF) were tested at 6 hours after operation. Syndromatology alteration of traditional Chinese medicine (TCM) and bleeding complications were observed at 4 weeks after operation. Both TF and vWF at 6 hours after operation of the treatment group was lower than the control group significantly (P < 0.01), while the condition of myocardial ischemia at 90 mins after operation of the treatment group was better than control group with significance. The syndromatology alteration of TCM especially spontaneous perspiration and hypodynamia of the treatment group were improved significantly compared to control group 4 weeks after operation. All patients in both groups had no bleeding complications and thrombopenia. The study suggests that Anxin granules combined with tirofiba can improve the clinical efficacy and the endothelial function of AMI patients after PCI with no increase in bleeding events.

OBJECTIVETo study the prevalence and clinical characteristics of the A to G mutation at nucleotide 3243 of the mitochondrial tRNA(Leu(UUR)) gene in familial diabetes in Shanghai, Jiangsu and Zhejiang Province of China.

METHODSThe mt3243 A to G mutation in 770 randomly selected, unrelated probands of diabetic pedigrees were screened by PCR-RFLP technique and PCR-direct sequencing. Genetic and clinical analyses were further performed in the probands and their family members.

RESULTSThirteen diabetic patients (13/770, 1.69%) with mt3243 A to G mutation were detected. Eleven diabetic patients and 8 normal glucose tolerance (NGT) first-degree relatives of these 13 probands were also found bearing the mutation. Seventeen patients were associated with sensory hearing loss. In the 24 patients harboring the mutation, the majority had lower body mass index (BMI), 18 showed typical maternal inheritance, 15 had sensory hearing loss, 13 had insulin resistance and 14 required insulin therapy due to secondary failure to oral hypoglycemic agents.

CONCLUSIONThe mutation of mt3243 A to G in the mitochondrial tRNA(Leu(UUR)) gene is an important cause of diabetes in Shanghai, Jiangsu and Zhejiang Province of China. Mitochondrial gene mutation diabetes (MDM) is clinically characterized by early onset, emaciation, maternal inheritance, sensorineural hearing loss, and lower islet beta cell function, and some have insulin resistance.

OBJECTIVETo investigate the efficacy of the Chinese medicine Huzhangdanshenyin on male immune infertility, and provide an effective therapy for this disease.

METHODSNinety men with immune infertility were selected as the research subjects and randomly divided into two groups, 60 in the treatment group, treated by Huzhangdanshenyin, and the other 30 in the control, treated by prednisone, both for 3 months. The improvement of clinical symptoms, immunologic indexes (antisperm antibodies in serum and seminal plasma) and sperm indexes (semen liquefied duration, motility, viability, density and abnormal morphology rate) were observed and the results analyzed.

RESULTSThe total antisperm antibody reversing ratio of the treatment group was higher than that of the control (P < 0.01), especially the serum antisperm antibody reversing ratio. There were significant differences in the clinical cure rate and total validity rate between the treatment group and the control (P < 0.01). After the treatment, the markers of the clinical symptoms (P < 0.01), especially the serum antisperm antibody reversing ratio. There were significant differences in the clinical cure rate and total validity rate between the treatment group and the control (P < 0.01). After the treatment, the markers of the clinical symptoms were lower (P < 0.01), and the improvement of the clinical symptoms was better in the treatment group than in the control (P < 0.01), especially the symptoms of pain in the back and knees, distending and bearing-down sensation of the perineum and testis, hypersexuality and topalgias. Compared with pre-treatment, sperm motility and viability of the treatment group significantly improved (P < 0.01), and so did sperm density (P < 0.05). However, there were no significant differences in sperm density, semen liquefied duration, abnormal morphology rate and pH (P > 0.05) before and after the treatment.

CONCLUSIONThe Chinese medicine Huzhangdanshenyin works more effectively than prednisone in the treatment of male immune infertility. It could improve the antisperm antibody reversing ratio, clinical symptoms and signs and ameliorate sperm indexes with no obvious advierse effects.

OBJECTIVETo investigate the genetic and clinical features of mutations and sequence variations of the transcription factor 1 gene (TCF1, HNF-1A) in Chinese with familial early-onset and/or multiplex diabetes mellitus.

METHODSAll ten exons of the TCF1 gene were screened, including exon and intron junctions, by direct sequencing method in 341 unrelated Chinese subjects, including 80 healthy controls and 261 probands of early-onset and/or multiplex diabetes pedigrees.

RESULTSFive mutations were found in all. Four of the 5 different TCF1 mutations were newly identified novel mutations(T82M, Q130H, G253G, P353fsdelACGGGCCTGGAGC), mean body mass index of mutation carriers was 21.9 kg/m (2), and insulin secretion was impaired in the mutation carriers. In this study, the maturity-onset diabetes of the young type III (MODY3) only accounted for 3% of Chinese early-onset diabetes. Moreover, eleven substitutions were identified in 261 probands. Of them, three variants IVS1-8 (G-->A), IVS1 -128 (T-->G ) and IVS2+21 (G-->A) were not observed in 80 healthy controls and one of them IVS1-8 (G-->A) was not reported previously and the two promoter variants co-segregated with diabetes.

CONCLUSIONTCF1 gene is not a common cause of early-onset and/or multiplex diabetes among Chinese patients.

OBJECTIVETo define the frequency and spectrum of c-kit gene mutations in gastrointestinal stromal tumors (GIST).

METHODSFifty two cases of GIST and 28 cases of other tumors were examined for mutations in exon 11, 9 and 13 of c-kit gene using PCR amplification and DNA sequencing.

RESULTSFourteen out of 25 malignant GIST (56%), while 2 of 27 benign and borderline GIST (7.4%) revealed mutations in exon 11 of c-kit gene (P < 0.01). Most of the mutations consisted of in-frame deletion or replication from 3 to 48 bp in heterozygous and homozygous fashions, but none of the mutations disrupted the downstream reading frame of the gene. Point mutation and deletion concentrated at 550 - 570 codons but replication clustered within 570 - 585 codons. The mutation pattern in recurrence tissues was the same as the primary ones. Normal tissues adjacent to GIST with or without c-kit gene mutations showed wild type c-kit gene sequence. No mutation was found in exon 9 and 13. Neither c-kit gene expression nor gene mutations was found in 3 leiomyomas, 8 leiomyosarcomas, 2 schwannomas, 2 intra-abdomenal fibromitoses and 8 adenocarcinomas.

CONCLUSIONThe mutations in exon 11 of c-kit gene might partially represent one of the molecular mechanisms of GIST. It can be used as a marker for distinguishing benignancy and malignancy of GIST. The mutations did not involve the reading frame. Except for long frame deletion, most mutations also did not affect protein expression. Mutation of c-kit gene in GIST provides a new genotypic marker to distinguish GIST from authentic leiomyomas, leiomyosarcomas, schwannomas and etc.

BACKGROUNDMutations in the hepatocyte nuclear factor-1A gene cause the type 3 form of maturity-onset diabetes of the young (MODY3). This study was undertaken to determine mutations and sequence variations of the HNF-1A gene in Chinese with familial early-onset and/or multiplex diabetes mellitus.

METHODSWe screened all ten exons of the HNF-1A gene, including exon/intron junctions, by direct sequencing in 272 unrelated Chinese, including 80 healthy controls and 192 probands of early-onset and/or multiplex diabetes pedigrees.

RESULTSIn addition to one silent mutation of c.864 G > C [p.G288G] in exon4 at codon 288, which had been reported previously, a total of four novel mutations including two missense mutations (c.245C > T [p.T82M] and c. 390 G > T [p.Q130H]) and one frameshift mutation P353fsdelACGGGCCTGGAGC and one silent mutation c.759 G > T [p.G253G] were identified. Moreover, eleven substitutions were identified in 192 probands. Of these, three variants (-8 G > A, -128 T > G and IVS2 + 21 G > A) were not observed in 80 healthy controls and one of them (-8 G > A) was not reported previously and the two promoter variants co-segregated with diabetes. The genotype and allele frequencies of the other eight variants in the diabetic patients were not significantly different from those in the healthy controls. No significant relationships were observed between the eight variants of the HNF-1A gene and clinical variables (plasma glucose, insulin, C-peptide and fasting lipid profile).

CONCLUSIONThe prevalence of structural mutations in the HNF-1A gene responsible for familial early-onset and/or multiplex diabetes appears to be rare among Chinese patients.

OBJECTIVETo assess the prevalence of mutations or variants of the mitochondrial DNA (mtDNA) in familial diabetes mellitus in Chinese population, and to explore the relationship between mtDNA mutations or variants and diabetes.

METHODSSeven hundred and seventy randomly selected, unrelated probands of diabetes pedigrees and 309 controls over 60 years of age with normal glucose tolerance were recruited. PCR-RFLP and PCR-direct sequencing were applied to the screening of mtDNA mutations or variants, including the mutations at nucleotides 3243, 3256 in tRNALeu region, 12258 in tRNASer region, 14709 in tRNAGlu region, 8296, 8344, 8363 in tRNALys region, 3316, 3394, 3426 in ND1 region and 12026 in ND4 region.

RESULTSIn the diabetic group, 13 (1.69%) had mt3243 A>G mutation, 9(1.17%) had tRNAGlu 14709 T>C variant, 17 (2.21%) carried mt3316 G>A variant, 18 (2.34%) had mt3394 T>C variant, and 28 (3.63%) harbored the 12026 A>G variant. In the control group, the 14709, 3316, 3394, 12026 variants were detected in 5(1.62%), 5(1.62%), 6(1.94%), and 9(2.91%) subjects respectively. The 3256, 8296, 8344, 8363, 3426 and 12258 point mutations were not detected both in the diabetic patients and the controls. In the diabetic group, we found two double mutations, one was A3243G and T3394C, the other was A3243G and A12026G. Except that the A3243G mutation was only observed in the diabetic group, the frequencies of the other variants mentioned above were not statistically different between the diabetic and control groups. Moreover, clinical characteristics such as age of onset, BMI, and insulin resistance index were not different between diabetic patients with and without the variants.

CONCLUSIONThe tRNA (LeuUUR) 3243 A>G mutation may be the major cause of diabetes, representing 1.69% of the familial diabetes mellitus in Chinese. The other variants may be polymorphisms in this population, and the mutations not detected in our studied population may not be common contributors to diabetes mellitus in Chinese.

OBJECTIVETo investigate the prevalence of mutations and sequence variations of glucokinase gene GCK in Chinese early-onset diabetes population.

METHODSThe study was conducted in 174 unrelated Chinese residents, including 80 nondiabetic controls, 94 probands of early-onset diabetes pedigree. Direct sequencing was performed to screen all 10 exons of glucokinase gene, including promoter and exon/intron junctions.

RESULTSNo mutations were identified in coding region, but several previously reported sequence variants were identified. 5'-untranslated region of exon 1a, 84 bp upstream of the translation initiation site GGCGG to GGGGG(early-onset diabetes group G allele frequency 0.106 vs control group 0.075, P=0.355); IVS1b+12 (A-->T) (early-onset diabetes group T allele frequency 0.005 vs non-identity of this variation in control group); IVS 5+29 (G-->T) (early-onset diabetes group T allele frequency 0.027 vs control group 0.019, P=0.731); IVS 9+8 (T-->C) (early-onset diabetes group C allele frequency 0.585 vs 0.694, P=0.044). A novel variation IVS 9+49 (G-->A) (early-onset diabetes group A allele frequency 0.011 vs control 0.006, P=1.000) was identified. There were no significant relationships of the exon 1a 5'-untransted region -84 bp(C-->G), IVS 5+29 (G-->T), IVS 9+8 (T-->C) and IVS 9+49 (G-->A) variants of GCK gene to the clinical variables such as plasma glucose, insulin, C-peptide and fasting lipid profile.

CONCLUSIONThe prevalence of structural mutations in glucokinase gene responsible for early-onset diabetes appears to be rare among Chinese patients.

Many Chinese medicinal materials, vegetable oils and extracts, and even Chinese patent medicines are spicy, which influences the medication compliance of patients, especially children. Different from the sour, sweet, bitter, salty, and umami tastes, it is a painful sensation formed when the spicy substances stimulate the nerve endings. At the moment, there are a few studies on the spicy components and mechanism and masking technology for the spicy flavor of Chinese medicine in the pharmaceutical industry, and the findings in food science are usually taken as a reference, which fail to guide the masking of the spicy flavor in Chinese medicine preparations. According to literature research, the exterior-releasing medicine, dampness-resolving medicine, and interior-warming medicine are spicy, especially some vegetable oils and extracts. Taking Zingiberis Rhizoma and prescriptions containing this medicinal as an example, the spicy components in Chinese medicine and the structure-activity characteristics were analyzed to reveal the mechanism for the spicy flavor: spicy components activate the transient receptor potential vanilloid subfamily member 1(TRPV1). The advantages and disadvantages of separation, neutralization with sugar, and inclusion for the masking of the spicy flavor were summarized and the applicability in Chinese medicine was analyzed. Moreover, the future development direction was put forward. This study is expected to promote the development of spicy masking technology for Chinese medicine prescriptions for children.
