RESUMEN
Objective:To analyze the related factors of neurotoxicity induced by oxaliplatin chemotherapy in patients with colorectal cancer and its prevention and treatment strategies.Methods:A total of 300 patients with colorectal cancer treated with oxaliplatin in Zhejiang Cancer Hospital from January 2018 to December 2020 were randomly selected for baseline collection using the convenience sampling method. The occurrence of oxaliplatin-induced peripheral neurotoxicity (OIPN) was statistically analyzed. The factors that affect the occurrence of OIPN were analyzed using univariate analysis.Results:There was a significant difference in OIPN score between patients of different genders, between patients who had different education levels, between patients who had different occupations, and between patients who lived in different long-term residence places ( t = 7.29, 3.39, 2.53, 18.11, all P < 0.05). There was no significant difference in OIPN score between patients adhering to different religion's beliefs, between patients married and not, between patients who lived with and without members, between patients who paid medical costs and not, and between patients who had a previous history of smoking and not ( t = 3.25, 0.37, 0.69, 2.39, 0.15, all P > 0.05). There was a significant difference in OIPN score between patients with different tumor-node-metastasis stages, between patients who received medication via different administration routes, and between patients who received different times of oxaliplatin administration ( t = 8.40, 3.34, 3.49, all P < 0.05). Conclusion:Medical staff should pay attention to the occurrence of OIPN in patients with colorectal cancer treated with oxaliplatin, focus on the patient's factors related to the disease, and take correct and effective coping strategies promptly to reduce the adverse reactions, improve the quality of life, and ensure the therapeutic effect.

Objective:To investigate the effects of Manchester Pain Management Model (MPMM) on postoperative pain and joint function for patients undergoing rotator cuff repair surgery.Methods:A total of 66 patients undergoing rotator cuff repair surgery from February 2017 to October 2020 in the First People′s Hospital of Hefei were divided into experimental group and control group by random digits table method, with 33 cases in each group. The control group received routine nursing; based on the routine care, the experimental group implemented MPMM-based intervention. The degree of pain and shoulder function of the two groups were assessed by Visual Analogue Scale (VAS) and Constant-Murley Scale (CMS).Results:During the study period, 1 case in the experimental group was lost, 32 cases in the final experimental group and 33 cases in the control group. There was no significant difference in the score of VAS and CMS before surgery between the two groups ( P>0.05). At 1 day, 3 days, 3 weeks and 6 weeks after surgery, VAS scores in the experimental group were 5.47 ± 1.72, 4.63 ± 1.16, 3.25 ± 0.78, 1.81 ± 0.52, lower than those scores in the control group 6.42 ± 1.03, 5.45 ± 1.54, 4.30 ± 0.64, 2.39 ± 0.47, the differences were statistically significant ( t values were 2.36-3.11, all P<0.05). At 3, 6, 12 weeks after surgery, CMS scores in the experimental group were 57.09 ± 4.32, 67.75 ± 4.60, 81.94 ± 4.18, higher than those scores in the control group 52.27 ± 5.39, 64.24 ± 3.76, 78.91 ± 4.36, the differences were statistically significant ( t=3.97, 3.37, 2.89, all P<0.01). Conclusions:MPMM can effectively alleviate the postoperative pain and promote the recovery of joint function in patients undergoing rotator cuff repair surgery.
RESUMEN
Objective To comprae the difference of Sex hormone,serum and follicular fluid anti Mullerian hormone (AMH) level tube,number of retrieved egg,the number of cleavage rate,fertilization oocytes,the number of available embryos and total embryo on in vitro fertilization and embryo transfer (IVF-ET) of different reaction groups,to explore the relationship between AMH and pregnancy outcome of IVF-EH.Methods Eighty-one cases of IVF-ET assisted pregnancy were divided into low ovarian response group,normal ovarian response group and high ovarian response group according to the response of the super ovulation.Serum sex hormone and AMH of all patients were detected on the third day of menstruation,on the day of HCG injection,oocyte pick-up (OPU) and embryo transfer (ET),AMH in FF were detected too.The difference of oocytes,cleavage rate,embryo quality and the indicators mentioned above among the three groups were compared.All of the above indicators were compared between pregnancy group and unpregnancy group.Results (1) The level of AMH on the third day of menstruation ((1.76 ± 0.47) μg/L,(3.45 ± 1.01) μg/L,(6.34 ± 1.29) μg/L,F =2.435,P＜0.001),HCG injection ((1.09±0.13)μg/L,(1.29±0.29)μg/L,(2.64±0.51)μg/L,F=1.542,P=0.001) and embryo planting((1.32±0.33) μg/L,(1.62±0.39) μg/L,(1o 91±0.41) μg/L,F =1.573,P ＜0.001) all were statistically significant in three groups.On day of OPU,the levels of serum AMH ((0.95±0.21)μg/L,(1.15±0.29) μg/L,(1.74±0.41) μg/L,F =12.573,P＜0.001) and AMH in FF((5.82±1.19) μg/L,(6.92±1.05) μg/L,(7.79±1.39) μg/L,F =9.83,P＜0.001) were statistically differences in the three groups.(2)The number of oocytes were positively correlated with AFC,based AMH,levels of E2,P and AMH on the day of HCG injection and OPU,E2 and AMH on the day of ET and AMH in FF(P＜0.05).(3)AMH in FF in pregnancy group was (6.22±0.82)μ g/L,significantly higher than those without pregnancy group ((5.31 ±0.71)μg/L,P =0.037).Conclusions Levels of AMH in serum and follicular fluid are good predictors of ovarian response in IVF-ET.The level of serum AMH can only predict ovarian response,but can not effectively predict pregnancy outcome.The level of AMH in FF is a good predictor of pregnancy outcome.
RESUMEN
Objective To assess the effect of a noninvasive equipment (the human biological stimulation feedback instrument) for the screening of metabolic syndrome (MS). Methods The samples were selected from the International Health Care Center of the Second Affiliated Hospital of Zhejiang University College of Medicine. From January to December 2012, according to the inclusion criteria, a total of 5674 consecutive participants (3 437 men, 2 237 women) without medical history of diabetes mellitus underwent general health screening in this hospital, which included questionnaire investigation, all MS components and the risk assessment of the human biological stimulation feedback instrument. MS was defined according to 2004 the Chinese Diabetes Society (CDS) criteria. Results The 5 674 subjects were divided into three groups in accordance with the human biological stimulation feedback instrument risk score: the normal group, metabolic abnormalities low risk group, metabolic abnormalities high risk group. The detection rate of MS corresponding to the three groups was 8.73% (251/2 876), 29.32% (612/2 087), 32.77% (233/711), respectively (trend χ2=372.14,P<0.001). With the increase of risk score, the detection rate of MS increased. A total of 1 096 (male 879, female 217) were diagnosed MS by CDS criteria. The area under the curve (AUC) of the test was 0.674 (95%CI 0.658-0.691, P<0.000 1)for predicting MS. The corresponding cutoff value was 25.00%, the sensitivity, specificity, positive predictive value and negative predictive value of diagnosis of MS was 77.80%, 56.00%, 30.20%and 91.30%, respectively;409 subjects who had no history of MS and diabetes mellitus follow up for two years, the AUC of the test was 0.719 (95%CI 0.644-0.794)for predicting MS. The corresponding cutoff value was 25.00%, too. And the sensitivity and specificity of diagnosis of MS was 78.00%and 59.80%, respectively. The detection rate of MS was positively correlated with the risk score. Conclusion We found that the human biological stimulation feedback instrument is a potential screening approach for early predicting MS in health checkup with simple and noninvasive procedure and high negative predictive value, although its diagnostic efficiency is not so good. And it might have a warning effect on the progress of MS.
RESUMEN
Objective To investigate the frequeney of four single nucleotide polymorphism (SNP) sites (rs17300539, rs12495941, rs2241766 and rs1501299) of adiponectin gene (ADIPOQ) and to elucidate its role in the pathogenesis of polycystic ovary syndrome (PCOS).Methods A total of 207 women with PCOS and 192 controls were recruited.Four ml whole-blood samples were collected in tubes containing ethylene diamine tetraacetic acid (EDTA) by peripheral venous puncture.Genomic DNA was extracted using a QIAamp DNA mini kit.Four SNP sites (rs17300539, rs12495941, rs2241766 and rs1501299) of ADIPOQ were amplified by PCR and then directly sequenced to screen variants.Results (1) The genotype frequencies of AA of rs17300539 in PCOS was significantly higher than controls [57.5％ (119/207) versus 48.4％ (93/192), P＜0.05].The genotype frequencies of AA of rs1501299 in PCOS was significantly lower than controls [4.8％ (10/207) versus 11.5％ (22/192), P＜0.05].While no significant differences were found in rs2241766 and rs12495941 (P＞0.05).(2) The allele A of rs17300539 [75.8％ (314/414)] and allele C frequeneies of rs1501299 [76.3％ (316/414)] in PCOS were significantly higher than controls [67.7％ (260/ 384), 69.0％ (265/384), respectively;all P＜0.05].While no significant differences were found in rs2241766 and rs12495941 (P＞0.05).(3) Further analysis we found rs17300539 AA genotypes had an increased risk for PCOS compared with GG genotype (OR=2.670, P=0.009), rs1501299 CC genotype had an increased risk for PCOS compared with AA genotypes (OR=2.756, P=0.012);and the difference remained significantly after adjustment for age, testosterone and body mass index (P＜0.05).Conclusions No signifi cant differences were observed in genotype and allele frequencies between PCOS and controls for rs2241766 and rs12495941.However, we observed an association between rs17300539, rs1501299 and PCOS.rs17300539 and rs1501299 of ADIPOQ perhaps are the susceptibility gene locus of PCOS.
RESUMEN
Objective To study the association between three single nucleotide polymorphisms (SNP; rs2241766,rs1501299 and rs12495941) variants of the adiponectin gene (ADIPOQ) and polycystic ovary syndrome (PCOS) in PCOS family trios.Methods A total of 224 unrelated PCOS probands,their biological parents were recruited.Anthropometric variables such as waist circumference (WC),hip circumference (HC),height and weight were measured in all subjects during the first visit to the outpatient department.Body mass index (BMI) and waist-hip ratio (WHR) were calculated.Serum fasting glucose (FBG),fasting insulin (FINS),total cholesterol (TC),triglycerides (TG),low-density lipoprotein and highdensity lipoprotein cholesterol (HDL) levels were measured.PCOS patients were divided into two groups based on BMh group A (BMI＜25 kg/m2) and group B (BMI≥25 kg/m2).Parents of PCOS patients were accordingly categorized into group C,D (fathers) and group E,F (mothers).The transmission disequilibrium test (TDT) was used to analyze the association between three SNP of ADIPOQ and PCOS.Results (1) A significant positive association was detected between SNP rs1501299 and PCOS (x2=7.093,P=0.008).However we failed to find significant overtransmission of the other two SNP rs2241766 and rs12495941 from parents to PCOS offsprings (x2=1.620,P=0.203; x2=0.713,P=0.398).(2) Linkage disequilibrium (LD) was analyzed in the subjects,rs1501299 and rs2241766 were in weak LD (r2=0.063,D'=0.621).(3) The levels of WC,HC,WHR,testosterone,TG,HDL and FINS were significantly differences between obese and lean PCOS patients (P＜0.05).While in fathers we only found WC,HC,TC levels being statistically different (P＜ 0.05).Mothers of obese PCOS patients had increased levels of FINS compared with mothers of lean PCOS patients (P＜0.05).The genotype frequencies of the three SNP were not different in obese and lean PCOS patients and their parents (P＞0.05).Conclusions TDT confirms that SNP rs1501299 in the ADIPOQ is significantly associated with the risk of PCOS in the Chinese Han population.The three SNP of the ADIPOQ were not associated with the obesity of PCOS.
RESUMEN
Acetohydroxyacid synthase (AHAS) catalyses the first reaction in the pathway for synthesis of the branched-chain amino acids. AHAS is the target for sulfonylurea, imidazolinone and other AHAS-inhibitor herbicides. Herbicides-resistant AHAS genes have potential application in plant transgenetic engineering and development of new generation herbicide. The AHAS isozyme genes ilvBN, ilvGM and ilvIH were cloned from metsulfuron-methyl resistant strain Klebsiella sp. HR11 and metsulfuron-methyl sensitive strain Klebsiella pneumoniae MGH 78578. Homologous sequences comparison indicated that the differences in AHAS isozyme genes at amino acid levels between strain HR11 and strain MGH 78578 were mainly on the large subunits of ilvBN and ilvGM. The three AHAS isozyme genes from HR11 and MGH 78578 were ligated into the expression vector pET29a(+) and expressed in Escherichia coli BL21, respectively. The results of enzyme inhibition assay showed that only ilvBN and ilvGM from strain HR11 showed strong resistance to AHAS-inhibitor herbicides, while ilvIH from strain HR11 and ilvBN, ilvGM and ilvIH from strain MGH78578 were sensitive to AHAS-inhibitor herbicides.
