Abstract
Objective: To investigate the association of cardiovascular diseases (CVD) with triglyceride glucose index (TyG) and TyG-related indicators in Uyghur populations of The Xinjiang Production and Construction Corps. Methods: Based on the cohort of the Uygur population of The Xinjiang Production and Construction Corps, 11 833 study subjects were included. The Kaplan-Meier method was used to estimate the cumulative incidence of CVD in each quartile of TyG and TyG-related indicators. Cox proportional hazards regression model was used to evaluate the relationship between TyG and CVD, TyG-related indicators and CVD. Framingham CVD risk score model (Framingham model) was used to evaluate whether the addition of TyG and TyG-related indicators could improve the predictive ability of the model. The potential mediating role of the TyG in the association between obesity and CVD was examined through mediation effect analysis. Results: The average age of the subjects was (37.00±13.67) years-old, and 51.0% were male. The median follow-up time was 5.67 years, with 1 288 CVD events. The cumulative incidence of CVD increased with the increase of TyG and TyG-related indicators quartiles, and compared with the Q1 group, the risk of CVD in the Q4 group of TyG, TyG-BMI, and TyG-WHtR increased by 20% (HR=1.20, 95%CI: 1.01-1.42), 77% (HR=1.77, 95%CI: 1.46-2.16) and 68% (HR=1.68, 95%CI: 1.36-2.09), respectively. After adding TyG, TyG-BMI, and TyG-WHtR to the Framingham model, respectively, the model's area under the curve, net reclassification improvement, and integrated discrimination improvement were improved. In the association between BMI, WHtR, and CVD, the proportion of mediating effects mediated by the TyG index was 10.55% and 11.50%. Conclusions: Elevated levels of TyG and TyG-related indicators were strongly associated with the risk of CVD in the Uyghur population of The Xinjiang Production and Construction Corps, with TyG-BMI being the most closely correlated with CVD. Early monitoring of TyG-BMI helps identify high-risk groups of CVD.

Methods: The Department of allergy, Beijing Shijitan Hospital Affiliated to Capital Medical University conducted a cross-sectional study about monitoring the airborne allergenic pollen from August 1, 2021 to July 31, 2022 by the gravitational method in 4 districts and 5 counties of Hohhot City, which include Yuquan District, Xincheng District, Huimin District, Saihan District, Tuoketuo County, Helingeer County, Tumotezuoqi County, Wuchuan County and Qingshuihe County. Daily pollens were counted and identified by optical microscopy, and the data were analyzed. Results: The airborne allergenic pollen was collected every month all year round in 4 districts and 5 counties of Hohhot city. Through the whole year of the total quantity of pollens ranged from 24 850 to 50 154 grains per 1 000 mm2 and two peaks of pollen concentration in air were observed,which happened in spring (from March to May) and in summer and autumn (from July to September). In spring, the main pollens were tree pollens, which principally distributed in Populus pollen (18.29%), Ulmus pollen (8.36%), Pinus pollen (6.20%), Cupressaceae pollen (5.23%), Betulaceae pollen (2.73%), Salix pollen (1.80%) and Quercus pollen (1.16%). In summer and autumn, the main pollens were weed pollens, which mainly included Artemisia pollen (42.73%), Chenopodiaceae pollen or Amaranthaceae pollen (7.46%), Poaceae pollen (2.26%), Humulus pollen or Cannabis pollen (0.60%). Conclusion: There were two peaks of main airborne allergenic pollen in 4 districts and 5 counties of Hohhot City. In the spring peak of pollen, the main airborne pollens were tree pollens. In the summer and autumn peak of pollen, the main airborne pollens were weed pollens. The Artemisia pollen was the most major airborne pollen in this area.

Abstract
Objective: To analyze whether triglyceride-glucose (TyG) index is associated with increased risk of cardiovascular diseases (CVD) and the value of TyG index in predicting CVD risk among Kazakh and Uighur population of Xinjiang. Methods: In this study, 5 375 Kazakh and Uygur people of Xinyuan county and Jiashi county were selected as the research objects. Subjects were divided into four groups based on the quartile of the TyG index level. Cox regression model was used to analyze the association between TyG index with the risk of CVD. The dose-response relationship between TyG index and CVD risk was described by restricted cubic splines. The area under the receiver operating characteristic curve, net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were used to estimate the value of TyG index for predicting CVD. Mediating effect analysis was conducted to analyze the mediating effect of TyG index in the association between body mass index and CVD. Results: The age of subjects was 41.06(30.11,53.00)years old, with 46.30%(2 489/5 375)was male. After multivariate adjustment, there was an increasing trend between the risk of CVD and the higher TyG index Ptrend<0.001, compared with subjects of TyG index in Q1, the HR (95%CI) of Q2, Q3, and Q4 groups was 1.53, 1.23 and 1.73, respectively. Restricted cubic splines showed that TyG index was the linearly associated with the risk of CVD. TyG index could improve the prediction ability of Framingham model for the risk of CVD (NRI=0.106,P=0.010; IDI=0.003,P=0.030). The mediating effect analysis showed that in the relationship between body mass index and CVD, the TyG index had a mediating effect (P<0.001), and the ratio of mediating effect was 12.69%. Conclusion: TyG index is an independent predictor of CVD risk among kazakh and Uygur population in Xinjiang and has a good predictive value for the risk of CVD.

Abstract
Genetic modification technologies can be used for modifying animal genome to express exogenous genes or affect the function of endogenous genes. In animal breeding, genetic modification technologies allow the rapid generation of germplasms with beneficial traits. It includes traditional genetic modification, virus or sperm carrier-mediated genetic modification and nuclease-mediated genome editing, especially the CRISPR/Cas9, one of the artificial nuclease genome editing technologies, have been applied in genome editing in many domestic animals including sheep (Ovis aries). Compared with conventional strategies used for animal breeding, there is great value for sheep breeding improvement by using genome editing technology, which is more effective and timesaving. In this review, we summarize the approaches of genetic modification in sheep and discuss the possibility of molecular design and breeding of sheep by genome editing technologies. We also identify the potential bottlenecks and challenges of these technologies in sheep breeding.

After nonpermanent residents were excluded, 12 154 individuals were included in this study. Questionnaire and physical examinations were conducted, including collection of fasting blood to detect TG, TC, LDL-C, and HDL-C. The results were calculated after complex weighting and compared according to the prevalence of different gender and age groups. Results: The overall levels of TG, TC, LDL-C, and HDL-C were 1.34±1.09, 4.45±1.16, 2.36±0.86, and 1.37±0.58 mmol/L, respectively. After complex weighting, the overall prevalence of dyslipidemia was 35.4%; that among men (42.9%) was greater than that among women (29.5%; χ2=234.19, P<0.001), and the prevalence was 35.9%, 34.5%, and 35.1% (χ2=1.52, P=0.467) in participants aged 18-44, 45-59, and ≥60 years, respectively. The overall prevalence of hypertriglyceridemia was 11.4%; that among men (13.5%) was greater than that among women (9.8%; χ2= 40.72, P<0.001), and the prevalence was 9.6%, 13.0%, and 13.2% (χ2=38.71, P<0.001) in participants aged 18-44, 45-59, and ≥60 years, respectively. The prevalence of hypercholesterolemia was 5.7%; that among men(5.0%) was greater than that among women (6.2%; χ2=6.95, P=0.008), and the prevalence was 3.5%, 7.4%, and 8.4% (χ2=105.24, P<0.001) in participants aged 18-4, 45-59, and ≥60 years, respectively. The prevalence of high blood LDL-C was 2.8%, and there was no significant difference between men (3.0%) and women (2.4%; χ2=1.43, P=0.231); the prevalence was 3.5%, 7.4%, and 8.4% (χ2=42.81, P<0.001) in participants aged 18-44, 45-59, and ≥60 years, respectively. The prevalence of low blood HDL-C was 24.0%; that among men (31.6%) was greater than that among women (18.0%; χ2=304.02, P<0.001), and the prevalence was 27.8%, 20.6% and 19.5% (χ2=96.61, P<0.001) in participants aged 18-44, 45-59, and ≥ 60 years, respectively. Conclusions: Low blood HDL-C was the main type of dyslipidemia among the population in remote rural areas of Xinjiang. The prevalence of dyslipidemia among men was greater than that among women, and there was a trend of younger men than women showing dyslipidemia.

Abstract
OBJECTIVE To explore the relationship between the polymorphisms and haplotypes in the CETP gene and dyslipidemia among Xinjiang Kazak and Uygur residents. METHODS A population status survey was performed from 2010 to 2011 in Kashgar Xinjiang Uygur and Kazak residents, stratified cluster sampling method was used to select Uygur, Kazak residents with abnormal blood lipid values (n=367 and 345, respectively) as the dyslipidemia groups, and to select residents with normal lipid values as control group from the same area (n=374 and 390, respectively). SNaPshot technology was applied to detect the DNA of CETP gene rs3764261, rs1800775, rs708272 and rs5882 loci in all selected residents, and linkage disequilibrium analysis and haplotype construction were performed. RESULTS (1) In Uygur residents, the dyslipidemia risk of rs708272 CT (OR=0.64, 95%CI 0.46-0.91, P=0.01) and TT genotype (OR=0.60, 95%CI 0.40-0.91, P=0.02) was significantly lower than CC genotype. Dyslipidemia risk of rs3764261 GT (OR=0.55, 95%CI 0.40-0.74, P=0.00) and TT genotype (OR=0.47, 95%CI 0.28-0.78, P<0.01) was significantly lower than GG genetype. Dyslipidemia risk of the rs1800775 CC genotype was higher than AA genotype (OR=1.79, 95%CI 1.17-2.74, P=0.01). There was no statistical significance in CETP gene of the 4 genotype and allele frequency between the dyslipidemia and normal lipid groups in Kazak residents (all P>0.05). (2) In Uighur residents with dyslipidemia, HDL-C level was significantly higher in rs708272 TT genotype carriers than in CC and CT genotypes (all P<0.05) and in rs3764261 TT genotype carriers than in GG genotype carriers (P=0.008), while was significantly lower in rs1800775 CC genotype carriers with AA genotype carriers (P=0.008). (3) Linkage disequilibrium analysis showed that there was strong linkage disequilibrium between rs3764261 and rs708272 (D'=0.869, r(2)=0.869), rs1800775 and rs708272 (D'=0.845, r(2)=0.446) in Uighur residents, and there was strong linkage disequilibrium between rs3764261 and rs708272 (D'=0.963, r(2)=0.963), rs1800775 and rs708272 (D'=0.988, r(2)=0.630) in Kazak residents. (4) Significant differences were observed in frequency distribution of haplotype GACA(OR=0.579, 95%CI 0.388-0.864, P=0.006), GATA (OR=2.183, 95%CI 1.231-3.873, P=0.006), GCCA (OR=0.723, 95%CI 0.549-0.954, P=0.001), TATA (OR=0.723, 95%CI 0.549-0.954, P=0.021) and TATG (OR=0.601, 95%CI 0.429-0.841, P=0.002) in Uighur residents with normal or abnormal lipid profiles, while significant difference was observed in frequency distribution of haplotype GCCG (OR=1.961, 95%CI 1.207-3.188, P=0.005) in Kazak residents with normal or abnormal lipid profiles. CONCLUSION CETP genotype rs708272, rs3764261 and rs1800775 polymorphism is closely related to dyslipidemia and haplotype GACA, TATA and TATG will reduce the risk of dyslipidemia, while haplotype GATA, GCCA will increase the risk of dyslipidemia in Uygur residents. The four CETP polymorphisms are not related to the risk of dyslipidemia, but haplotype GCCG is related to increased risk of dyslipidemia in Kazakhs residents.

Abstract
The aim of this study was to investigate the potential association between apolipoprotein A1 (APOA1) gene rs670, rs5069, and rs2070665 polymorphisms and dyslipidemia in the Kazakh population of Xinjiang, China. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) was used to identify APOA1 (rs670, rs5069, and rs2070665) genotypes in 736 subjects (341 dyslipidemia patients and 395 control subjects). The frequencies of the CC genotype for rs1421085 were found to be 7.2% (obese group), 4.4% (overweight group), and 5.6% (control group). Polymorphisms of the three loci of the APOA1 gene in Kazakh subjects met Hardy-Weinberg equilibrium. The frequencies of the A allele for rs670 were found to be 14.3% (dyslipidemia group) and 12.7% (control group). The frequencies of the T allele for rs5069 and rs2070665 were: dyslipidmia group (7.2 and 30.1%, respectively) and control group (7.7 and 32.5%, respectively). Frequency distributions of the 3 types of genotypes and alleles of the three loci showed no statistically significant difference (P > 0.05). Significant differences were observed in lipoprotein (α) [Lp(α)] between patients with the rs2070665 CT + TT and CC genotypes (P < 0.05); however, none of the other relevant indicators differed significantly between the two genotypes. No significant association was identified between rs670 or rs5069 and the lipid-related metabolic indices assessed in the study. These findings indicate that the polymorphisms in the APOA1 gene (rs670, rs5069, and rs2070665) are not associated with dyslipidemia in the Kazakh population assessed in this study.

Abstract
The aim of this study was to assess the association between three FTO polymorphisms (rs9939609, rs8057044, and rs1421085) and metabolic syndrome (MS)-related outcomes in the low-income, rural, nomadic minority Khazakh population in far western China. A total of 489 subjects (245 MS patients, 244 controls) were included in the study and DNA samples were genotyped for the three polymorphisms by matrix-assisted laser desorption/ionization time of flight mass spectrometry. The frequencies of the rs1421085 and rs9939609 genotypes and alleles did not differ significantly between MS patients and control, while the frequencies of rs8057044 G alleles and GG genotypes were higher in MS patients (P < 0.05) than in control subjects (G: 61.16 vs 53.53%, GG: 39.07 vs 29.05%) and the frequencies of rs8057044 A genotypes and alleles were lower (P < 0.05) in MS patients compared with controls (AA: 17.36 vs 21.99%, A: 38.84 vs 46.47%). Risk analysis of the rs8057044 polymorphism revealed individuals with GA and GG genotypes to have 1.112 and 1.731 times higher risks of developing MS than those with the AA genotype, respectively, while the G allele was found to be associated with a 1.367 times higher risk of developing MS compared with the A allele. These apparent correlations, however, did not hold true when adjusted for BMI. Weight, WC, HC, and BMI differed significantly between rs8057044 GG and AA+GA genotypes (P < 0.05).

Abstract
This study aims to investigate the mechanisms involved in the action of lutein (LU) alleviating arsenic-induced reproductive toxicity using mice model. Forty male Kunming mice were received following treatments by gavage: normal saline solution (control), arsenic trioxide (ATO; 5 mg/kg/day), LU (40 mg/kg/day), and ATO + LU (5 mg/kg/day + 40 mg/kg/day). At the end, the mice were killed by cervical dislocation and weighed. Pathological examination was done on the testis. The biomedical parameters including superoxide dismutase (SOD), glutathione (GSH), total antioxidative capability, malondialdehyde (MDA), 8-hydroxydeoxyguanosine (8-OHdG), and reproductive indexes were analyzed. The messenger RNA (mRNA) and protein expression of Nrf2, heme oxygenase 1 (HO-1), glutathione S-transferase (GST), nicotinamide adenine dinucleotide phosphate dehydrogenase, quinone 1 (NQO1) in testis were detected by real-time polymerase chain reaction and Western blot. We found that there was a decrease in sperm count; testis somatic index; the activities of SOD, GSH, total antioxidative capacity ( p < 0.01, respectively) in ATO-treated mice, while there was an increase in the levels of sperm abnormalities, MDA, and 8-OHdG than control ( p < 0.01, respectively). The groups treated with ATO + LU showed recovery of the measured parameters between those of ATO or saline-treated group. The antagonized interaction between ATO and LU was statistically significant ( p < 0.01). Mice treated with ATO + LU also showed greater mRNA expression of Nrf2, HO-1, NQO1, and GST than ATO or saline-treated groups. These findings suggest that LU alleviates reproductive toxicity induced by arsenic in male mice via Nrf2 signaling, which implicates a possible mechanism of LU in preventing the reproductive injury, and elucidates that consuming the rich plant sources of LU will alleviate the reproductive toxicity induced by chemicals.

Abstract
We investigated the association between polymorphisms rs1801282 and rs3856806 of the PPARγ gene and metabolic syndrome (MS) among Uyghurs and Kazakhs. Mass spectrometry techniques were used to detect the PPARγ genotypes rs1801282 and rs3856806 in 987 subjects, CC genotype and C allele frequencies were 83.6 and 91.7%, respectively, at rs1801282 in Kazakhs, which were higher than those in Uyghurs (72.3 and 85.0%, respectively; P < 0.05). CC genotype and C allele frequencies were 73.6 and 85.3%, respectively, at the rs3856806 loci in Kazakhs, which were higher than those in Uyghurs (60.7 and 77.9%, respectively; P < 0.05). For the rs3856806 polymorphism in Kazakhs, CT/TT genotype and T allele frequencies were 21.2 and 12.4% for MS subjects, which were lower than those for the control group (31.6 and 17.0%, respectively; P < 0.05). Risk analysis of Kazakhs revealed that individuals with the CT and TT genotypes at rs3856806 had an increased risk, 0.524- and 0.770-fold, respectively, of developing MS than those possessing the CC genotype. Individuals with the T allele also had an increase in risk, by 0.699-fold, of developing MS than those with the C allele. For Uyghurs, those with the CC genotype at rs1801282 had higher systolic blood pressure than those with the CG/GG genotype. Among Kazakhs, those with the CC genotype at rs3856806 had higher triglyceride and waist-hip ratio levels but lower high-density lipoprotein cholesterol levels than those with the CT/TT genotype. The rs1801282 and rs3856806 PPARγ polymorphisms differ between Uyghurs and Kazakhs from Xinjiang Province, China.

Abstract
The traditional Chinese medicine Artemisia annua can prevent and treat hepatitis following an unclear mechanism. The aim of this study was to evaluate the effects of A. annua polysaccharides (AAP) on hepatitis C virus (HCV). A pcDNA3.1/NS3 expression vector was constructed. Ninety female BALB/c mice were randomly divided into six groups: high-dose AAP (1 mg/mL) + HCV/NS3 plasmid; middle-dose AAP (0.5 mg/mL) + HCV/NS3 plasmid; low-dose AAP (0.1 mg/mL) + HCV/NS3 plasmid; HCV/NS3 plasmid; high-dose AAP (1 mg/mL); normal saline control (N = 15). Except the control group and the high-dose AAP group, other groups were inoculated with 50 μg pcDNA3.1-HCV/NS3 plasmid. Serum antigenic-specific antibody was detected after the last immunization, and the levels of secreted IFN-γ and IL-4 were measured. pcDNA3.1/NS3 plasmid was successfully constructed, and the extracted product contained HCV/NS3 sequence. Compared with single inoculation with HCV/NS3 DNA vaccine, the specific antibody levels induced by middle-dose AAP plus HCV/NS3 DNA vaccine were significantly different in weeks 1, 3 and 5 (P < 0.05). However, there were no significant differences in the antibody levels induced by high-dose and low-dose AAP as adjuvant compared with those of single inoculation with DNA vaccine (P > 0.05). The level of serum IFN-γ secretion was significantly higher than that of IL-4 secretion. Compared with the single HCV/NS3 DNA vaccine group, AAP plus HCV/NS3 DNA vaccine groups had significant increased IFN-γ levels (P < 0.05), but the IL-4 levels were not significantly different among these groups (P > 0.05). AAP, as the adjuvant of HCV/NS3 DNA vaccine, can widely regulate the humoral immunity and cellular immune function of normal and cyclophosphamide-induced immunocompromised mice. AAP can promote IFN-γ secretion probably by inducing Th1-type cellular immune response.

Abstract
This study investigated the prevalence and distribution of dyslipidemia in adults of Uygur, Kazak, and Han ethnicity in Xinjiang, China. A questionnaire including general data, physical examination (blood pressure, body height, and body weight) and blood lipid [total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C)] was administered to 11,506 adults in Xinjiang, China from 2009 to 2010 using a stratified sampling method. The overall prevalence rates of dyslipidemia in Uygur, Kazak, and Han adults were 42.4, 31.6, and 30.2%, respectively; they were 42.4, 31.8, and 28.2% after age standardization (P < 0.01). After standardization, the overall prevalence rates in Uygur, Kazak, and Han men were 52.6, 35.4, and 33.2%, respectively, which were significantly higher than that in women of the corresponding ethnicities (P < 0.01). In Uygur, Kazak, and Han adults, there were significant differences with respect to the standardized prevalence rates of high TG (9.3, 9.3, and 17.3%), high TC (5.2, 6.9, and 6%), low HDL-C (33.6, 20.8, and 11.1%), and high LDL-C (2.4, 2.9, and 2%) (P < 0.05). The prevalence rates of dyslipidemia in Uygur, Kazak, and Han adults in Xinjiang are higher than the average levels in China, with significant differences in ethnicity, age, and gender. Han adults exhibited the highest prevalence rate of high TG. Meanwhile, Uygur adults had the highest prevalence rate of low HDL-C. Kazak adults had high prevalence rates of high TC, low HDL-C, and high LDL-C.

Abstract
Previous DNA sequencing of BAC clones covering entire ovine MHC (OLA) region resulted in identification of approximately 130 functional genes in the region, of which 8 were predicted by computer software to be exclusively existed in sheep, but not in any other species known to date. In the present study, we successfully identified and cloned cDNA sequence of OaN2, OaN5, and OaN6 from representative sheep tissues, confirmed their existence in reality. The sequences obtained experimentally exactly identical to those predicted previously. The length of cDNA fragments for OaN2, OaN5, and OaN6 was 270 bp, 309 bp, and 205 bp, respectively, with GenBank accession number assigned as JF330782 (OaN2), JF330783 (OaN5), and JF330784 (OaN6). Northern analyses indicated that the mRNA transcripts of OaN2 were mainly seen in ovine mesenteric lymph nodes and spleen, while OaN5 was observed in only in mesenteric lymph nodes. In contrast, OaN6 transcripts were detected in all tissues except for liver and heart. Western blot showed that OaN2 protein expression level was detected in mesenteric lymph nodes, spleen, and liver, essentially consistent with that of mRNA transcripts. Immunohistochemistry analysis showed that OaN2 protein was highly expressed in ovine mesenteric lymph nodes, moderately expressed in, and not expressed in heart, liver, and pancreas, consistent with the results of Western blotting. The cloning and expression analysis of 3 novel genes provide a basis for revealing their specificities and would be helpful to further study of their expression profile and their potential functions.

Abstract
Production of transgenic animals via somatic cell nuclear transfer (SCNT) has been widely used worldwide. However, the application of SCNT is impeded by overall high costs and low efficiency. Here, we reported a modification of the existing technology in order to overcome some of the disadvantages associated with SCNT. Firstly, a marker gene, enhanced green fluorescent gene (EGFP), was transfected into pig fetal fibroblast cells, and was subsequently screened by fluorescent expression to ensure donor cells expressing EGFP. Porcine embryos expressing EGFP were then produced by a method called handmade cloning (HMC), a simplified method for micromanipulation. To demonstrate the concept, we collected a total of 378 fresh swine oocytes, from which 266 with the nucleus removed, obtained a total of 127 viable recombinant oocytes after fusion with EGFP-expressing cells. In vitro incubation of the 127 recombinant oocytes for approximately 144 hours resulted in successful generation of 65 viable embryos, with an average success rate of 52.1±8.3%. Compared with the traditional SCNT, the method of HMC is not only easy to operate, but also increases the rate of recombinant embryo significantly. Furthermore, the modified method no longer relies on expensive instrument like micromanipulator, facilitating the industrialization of transgenic animal production.

Abstract
To detect HPV in genital warts (Condylomata acuminata, CA) for infection rate and association of specific HPV types between males and females, and to provide support for the development of HPV vaccines, we designed HPV type-specific oligonucleotide primers to amplify DNA fragments encoding L1 viral capsule protein. SSP-PCR was conducted in duplication for each CA sample from male and female patients. DNA of TA-cloned HPV was used as positive control, and deionized H2O was used as negative control. A total of 22 clinical samples, 13 from males and 9 from females, was collected from patients diagnosed with CA at hospitals in Beijing and Handan. HPV viral DNA was amplified in all 22 samples analyzed, with 100% detection rate. TA-cloning and sequencing of the PCR products confirmed correct amplification of HPV type-specific fragments. Of the 13 samples from males, 5 were infected with HPV6, 6 with HPV11, and 2 with HPV6 + HPV11. Of the 9 samples from females, 3 were infected with HPV6, 2 with HPV11, and 4 with both HPV6 and HPV11 infection. In addition, high-risk types HPV16, HPV18, HPV33, HPV35, HPV45, HPV54, HPV56 and HPV58 were also detected in 4 female samples that were mixed with cervical cell debris during sample collection. However, no HPV types other than HPV6 and HPV11was detected in all CA-only samples in this study. We have established a sensitive and reliable laboratory procedure for HPV detection and classification. Using the method, we reached 100% detection rate of HPV in the CA samples. Our results confirm that HPV6 and HPV11 are primarily responsible for CA, and there is no specific association of HPV types between warts in males and females.

Abstract
It was found that the level of Calponin h1 (CaP h1) mRNA was significantly up-regulated by Estrogen in the myometrium of sheep towards the end pregnancy. Although the CaP h1 has been widely used as a reference gene to observe the changes of expression level of other genes, the full-length gene in sheep has not been obtained. With the oligo nucleotide primers according to human, mouse and pig CaP h1 mRNA, the full-length cDNA of CaP h1 was cloned by 5'- and 3'-RACE (Genbank accession number = AY327118). The cDNA was 1499bp in length and contained a complete open reading frame of 891 bp, encoding a protein of 297 amino acid residues. 5'-and 3'-UTR was 79 bp and 529bp, respectively. With PCR-SSP approaches,the genomic DNA of sheep CaP h1 was obtained .It showed that the gene has 7 exons and 6 introns, spanning over 8kb(Genbank accession number of introns : AY771807,AY771808, AY771809, AY771810.) Homologous comparison indicated that the cDNA sequences are highly conserved across the species. The highest homology was found in wild pig (92%), followed by human (88%), rat (81%), mouse (81%) and chicken (79%). The intron sequence and length showed a large variation among species (>50%).

Abstract
Nucleotide sequence of fish mitochondria DNA (mtDNA) D-loop region from Leuciscus leuciscus baicalensis, L. merzbacheri, and L. idus in Xinjiang, China, were examined by sequencing 667 - 669 bp length of homological fragments in the D-loop from 24 individuals of the three fish species. DNA divergence ranged from 6.39% - 9.89% among the three fish species in the genius of Leuciscus cuvier. The sequence similarity is high and the variation is low between L. Leuciscus baicalensis and L. idus. In contract, the genetic distance is larger between L. Leuciscus baicalensis and L. merzbacheri. The average nucleotide variation within each of the two geographical populations (Sailimu lake and E' erqis river) of L. leuciscus baicalensis is 1.07% and 1.08%, respectively, and such variation is 1.07% between the two populations. These results demonstrate that the two geographic populations of L. leuciscus baicalensis do not appear to have significant genetic differentiation. Sequencing data showed the existence of sufficient genetic variations among three species of fish, as illustrated by distinct haplotypes for each species. The phylogenetic trees built with MEGA1.02 pointed out that the relationship between L. leuciscus baicalensis and L. idus is close, and L. merzbacheri is ancient among three Leuciscus.

Abstract
Mater encoding an oocyte-specific autoantigen,and is associated with premature autoimmune ovarian dysgenesis (AOD) in mouse. Based on RT-PCR, cDNA cloning, screening, sequencing and analysis, we have detected a total of four Mater splice variants, designated as variant B, E, F and G. All these splicing forms are in frame in terms of expected protein products. Among these, B was consistent with the previous report, whereas E, F, G belong to novel splice variants that have not been reported previously. Variant E lacks exon 6, variant F both lacks exon 10 and retains a part of intron 8, variant G lacks part of exon 14, and variant H lacks part of exon 13. The cDNA sequences at all the exon-intron boundaries confirms to the "GT-AG" splicing rule. Variant B, E, F exist in all the four strains. Variant G exists only in SWR/J. According to the cDNA sequences of these four splice variants, amimo acid sequences of the corresponding expected protein isoforms were deduced, and their potential functional effects were predicted in this thesis. Further identification and characterization of these expected protein isoforms would provide valuable information for their functional importance.

Abstract
We report here the identification of three additional murine SmX5 alternative transcripts, designated SmX5a, b and c. The cDNA of SmX5a possesses intron 1 in its entirety, and SmX5b harbors a part of intron 2. The retained fragment of SmX5c starts at the same position as SmX5b, but the retention extends through the remaining portion of intron 2. The sequence of retained DNA at all the intron-exon boundaries conforms to the "GT-AG" rule. RT-PCR analysis indicates that the three isoforms are stable transcripts, all at low frequency when compared with SmX5. Expression analysis by RT-PCR indicates that SmX5 and its isoforms exist in murine brain, kidney, testis, thymus, liver, spleen and heart. The SmX5a isoform is predominantly expressed in the thymus, while SmX5b and c are expressed in all tissues examined. The presence of alternatively spliced SmX5 isoforms and tissue-specific variation in splicing patterns suggests that SmX5 expression is complex and that the regulation of all four SmX5 mRNA levels may be critical in maintaining proper pre-mRNA splicing machinery in different cell types.

Abstract
The gene encoding a putative mature antitumor-analgesic peptide (AGAP) from the venom of the Chinese scorpion Buthus martensii Karsch was obtained by polymerase chain reaction (PCR) according to its cDNA sequence and expressed in Escherichia coli. While most of the recombinant AGAP was expressed in the form of insoluble inclusion body. The recombinant AGAP was purified to homogeneity by metal chelating affinity chromatography. Pharmaceutical tests showed that the recombinant AGAP has both analgesic and antitumor activities on mice.
