Objective To study the relationship between the prevalence of thyroid dysfunction and components of metabolic syndrome.Methods A total of 10 461 working and retired employees aged 20 to 90 years in a Petrochemical Corporation in Ningbo were included.Body mass index ( BMI),waist circumference,blood pressure,fasting blood glucose,blood lipid profile,serum thyroid-stimulating hormone (TSH),free thyroxine ( FT4 ),and free triiodothyronine (FT3 ) were measured in all subjects. Metabolic syndrome was diagnosed according to the International Diabetes Federation(IDF) criteria.Results ( 1 ) The prevalences of metabolic syndrome and overall thyroid dysfunction were 10.2％ and 4.6％,respectively. ( 2 ) 18.1％ petrochemical employees had abdominal obesity with at least one component of metabolic syndrome.( 3 ) There was no significant difference in the prevalence of metabolic syndrome among the groups with lowered,normal,and elevated TSH. (4) Logistic regression analysis revealed that lowered high density lipoprotein cholesterol ( HDL-C ) was associated with lowered TSH ( OR =0.313,95％ CI 0.184-0.530 ),and raised triglyceride was associated with elevated TSH ( OR =0.767,95％ CI 0.595-0.991 ). ( 5 ) There were significant associations between serum TSH levels and lipid parameters such as total cholesterol in males,triglyceride and low density lipoprotein cholesterol in females,and HDL-C in both genders.Conclusion The prevalence of thyroid dysfunction was not associated with central obesity,hypertension,and hyperglycemia.Lipid disorder was correlated with serum TSH levels.

Objective To explore the relationship between thyroid hormone and colorectal adenomatous polyps (CAP) in middle-aged and elderly people.Methods We surveyed 3 042 middle-aged employees and retirees aged 45 years and over at a petrochemical enterprise of Ningbo.Their colonoscopic findings,body mass index,waist circumference and thyroid function were analyzed.Results Age and serum free triiodothyronine (FT3) of females with CAP were higher than those of the corresponding non-CAP group,so were age and waist circumference of males with CAP (P ＜ 0.05).Furthermore,these differences were statistically significant.The detection rate of CAP was significantly higher in males than in females (x2 =49.418,P ＜ 0.01).The detection rate of CAP was higher in females with higher levels of FT3.Multivariate unconditional logistic regression analyses showed the effects of thyroid hormone on the CAP differed by gender.Age and FT3 (OR =1.60,95％ CI:1.12-2.28,P =0.01) were correlated with CAP in females.However,only age and waist circumference were correlated with CAP in males.Conclusion Elevated FT3 may be a risk factor of CAP in elderly females.The detection rate of CAP may not be affected by FT3 levels in males.

Objective:To study the association between non-syndrome cleft lip and palate (NSCL/P)and MAFB (rs6072081, rs6065259,rs17820943,rs11696257)gene polymorphism in NingXia Hui and Han population.Methods:512 cases of NSCL/P,258 case of Hui nationality and 254 of Han,174 cases of complete 3 core family members(patients and their parents),142 cases of single parents families(patients and their single parents),were collected in patient group.505 cases of healthy newborns were collected in control group.The MAFB gene SNPs were determined with TaqMan SNPs genotyping methods and the data were analyzed by case-con-trol analysis,transmission disequilibrium test(TDT)and family based association test(FBAT).Results:Case-control analysis found that,there was a statistical significance of the genotypes and allele frequency between patients and the controls in MAFB of the 4 locus (P <0.05);but all of the 4 locus showed no difference in patients with cleft palate(P >0.05).Conclusion:The 4 locus single nucle-otide polymorphism was associated with NSCL/P in Ningxia population.

Objective To evaluate the role of multi-slice CT (MSCT) perfusion in early diagnosis of liver fibrosis. Methods Thirty-three subjects underwent CT perfusion of the liver. Among whom, 11 subjects were volunteers without hepatic disease and the other 22 subjects were pathologically confirmed with liver fibrosis who were further divided into slight (n= 10) and severe (n=12)liver fibrosis according to the lshak system. Parameters of CT perfusion were measured and compared among three groups. Results The mean hepatic arterial fraction in controls, light and severe fibrosis tended to increase with the severity of liver fibrosis[(18. 49 ± 9. 69) %, (19. 92 ± 6.01) % and (21.31±7.47)% ,respectively], and the mean mean transit time tended to decrease with the severity of liver fibrosis [(13.80 ± 2. 60) s, (12.35 ± 1.31) s and (12.19 ± 3.33) s, there was no significant difference in all parameters between any two groups (P>0.05). Conclusions Quantitative measurement of hepatic blood supply can be obtained by CT perfusion. Some parameters will be helpful in staging fibrosis to a certain extent. But its clinical usefulness for the evaluation of the early diagnosis may not be affirmed yet.

Objective To evaluate the effect of doxepin on the expression of p38 mitogen-activated protein kinase (p38 MAPK) in the spinal cord of rats with neuropathic pain (NP).Methods Sixty clean-grade male Wistar rats in which intrathecal catheters were successfully implanted,weighing 200-250 g,were divided into 3 groups (n =20 each) by a random number table method:sham operation group (S group),NP group and doxepin group (D group).NP was induced by chronic constriction injury (CCI) to sciatic nerve.Doxepin 20 mmol/L (10 μl) was intrathecally injected at 3,7,14 and 21 days after CCI (T1-4) in group D.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 1 day before CCI (T0) and at T1-4.The rats were sacrificed after measurement of pain threshold at T4,and L4-6 segments of the spinal cord were removed for determination of the expression of p38MAPK protein by Western blot.Results Compared with S group,MWT was significantly decreased and TWL was shortened at T2-4,and the expression of p38MAPK protein was up-regulated in NP and D groups (P＜0.05).Compared with NP group,MWT was significantly increased and TWL was prolonged at T2-4,and the expression of p38MAPK protein was down-regulated in D group (P＜0.05).Conclusion The mechanism by which doxepin mitigates NP is related to down-regulating p38MAPK expression in the spinal cord of rats.

Objective:To investigate the clinical diagnostic value of MRI retention enema cannula enhanced scanning in the high complex anal fistula.Methods:The clinical data of 60 anal fistula patients underwent surgery treatment from May 2020 to May 2022 in Affiliated Hospital of Shanxi University of Traditional Chinese Medicine were retrospectively analyzed. All patients underwent MRI plain scanning and enhanced scanning before operation. Compared with the surgical results, the difference between MRI plain scanning and enhanced scanning in the diagnosis of high complex anal fistula was compared.Results:All of the 60 patients successfully completed surgical treatment, and 58 cases internal orifices, 55 cases complex anal fistulas and 53 cases high anal fistulas were found intraoperatively. MRI plain scanning results showed 32 cases internal orifices, 46 cases complex anal fistulas and 42 cases high anal fistulas were found. MRI enhanced scanning results showed 54 cases internal orifices, 53 cases complex anal fistulas and 50 cases high anal fistulas were found. Based on surgical results, the coincidence rates of internal orifice, complex anal fistula and high anal fistula in MRI enhanced scanning were significantly higher than those in MRI plain scanning: 93.10% (54/58) vs. 55.17% (32/58), 96.36% (53/55) vs. 83.64% (46/55) and 94.34% (50/53) vs. 79.25% (42/53), and there were statistical differences ( χ2 = 21.76, 4.95 and 5.27; P<0.01 or <0.05). Conclusions:The MRI retention enema cannula enhanced scanning has obvious advantages in the diagnosis of high complex anal fistula, which provides scientific reference value for the diagnosis and operation of high complex anal fistula in clinic.

Objective To provide new ideas for promoting wound healing by digging and sorting out the medication rules in ancient classics and modern literatures. Methods The prescriptions for promoting wound healing recorded in literatures were collected to establish the database. The data mining technology was used for the analysis. Results 75 prescriptions and 203 traditional Chinese medicines were recorded in the ancient TCM literatures for promoting wound healing. The core medicines included frankincense, liquorice, angelica sinensis, angelica dahuricae, cortex phellodendri, myrrh, etc. They mainly belong to the class of clearing-heat drugs, promoting-circulation drugs, reinforcing drugs, relieving drugs, detoxification and tissue granulation drugs. Cluster analysis and association rule analysis were conducted for 16 core drugs. 4 cluster combinations ,15 groups of drug pairs and drug group association rules were obtained. Conclusion The prescription rules for wound healing mainly included clearing heat, promoting circulation, reinforcing, relieving, detoxification, and promoting tissue granulation. TCM wound treatment should be based on syndrome differentiation for fever, blood stasis, deficiency, anabrosis, exterior syndrome and poisoning.

Objective: To discuss the affect of glycosylated hemoglobin (HbA1c) level for the onset of nonalcoholic fatty liver disease (NAFLD) in cohort population. Methods: An epidemiological survey of the relationship between HbA1c and NAFLD conducted in 2012 was based at cohort baseline, and three follow-up sessions conducted in 2013, 2014 and 2015. In total 2 811 subjects were included in the study after exclusion of NAFLD patients at baseline and those who lost their lives due to relocation, and death. The Cox proportional hazard model was used to analyze the relationship between glycosylated hemoglobin and other risk factors of NAFLD. Continuous variables were compared using the t-test or the Mann-Whitney test. χ ²-test was used for the measurement of categorical data. Results: A total of 2 811 subjects with mean age of 59 (58.2±9.8) years old, including 1 664 males and 1 147 females. Age, waist circumference, body mass index, systolic blood pressure, γ-glutamyltransferase and fasting blood glucose level of HbA1c abnormal group were higher than normal group. The incidence of NAFLD in the abnormal HbA1c level group (25.4%) was higher than normal group (14.9 %), and diastolic blood pressure, high-density lipoprotein cholesterol was lower than normal group and the differences were statistically significant. During the three follow-up intervals, there were 440 new cases of NAFLD, consisting 285 males and 155 females with cumulative incidence of 15.7% (440/2 811). Multivariate Cox regression analysis showed that patients with elevated HbA1c had a higher risk of developing NAFLD (HR 1.796; 95% CI 1.335~2.418; P < 0.01), and the increased HbA1c level after adjustment for gender, age, and metabolic syndrome-related factors remained an independent risk factors for NAFLD (HR 1.580; 95.0% CI 1.161-2.152; P < 0.01). Conclusion An elevated HbA1c levels have a positive predictive value for the onset of NAFLD.
