Objective:To explore the genotype distribution of lipoprotein lipase polymorphism at Pvu Ⅱ locus and its possible association with serum lipid levels, body mass index (BMI) and dietary intake. Method:Pvu II polymorphism was determined by PCR-PFLP method in 156 adults with hyperlipidemia and 154 adults with normal serum lipid levels as control in Shanghai. Their physical examinations, dietary investigation and the levels of serum lipid profile, including TG, TC, HDL and LDL were analyzed. Results: ⑴ There was no significant difference in frequencies of genotypes or allele between the hyperlipidemia and the control, and between male and female. ⑵ BMI were significantly different between P-P-and P+P+, P+P-genotype groups. The BMI of subjects with genotype P+P+ had the highest levels. The relationship was significant after adjusting several confounding factors such as age, gender and blood lipid (P

Objective To evaluate the chnical value of intervention therapy combined with the foot plastic surgery in the treatment of diabetic foot.Methods 67 patients who accepted the intervention therapy combined with the plastic surgery for occlusive lesion of lower limbs arteries were selected.The clinical symptom,ankle brachial pressure index and hemodynamics were observed before and after treatment.All clinical indicators were compared between the therapeutic group and the control group.Results Among 67 patients,63 cases were successful in clinical treatment (the success rate:94.0％).One month,three months,six months after operation,the skin temperature,anklebrachial index,limp distance,clinical symptom,ankle brachial pressure index and hemodynamics were increased.Compared with preoperation,all above-mentioned indicators were improved obviously (P ＜ 0.05,P ＜ 0.01).Conclusion Intervention therapy for diabetic foot has the merits of less trauma,higher effectiveness of treating diabetic foot ulcers,defect repair,maximally reserved limbs and better shapes of limbs,which made both doctors and patients satisfied.It is a new direction for minimally invasive therapy.

OBJECTIVETo investigate the effects of different concentrations of lipopolysaccharide (LPS), tumor necrosis factor α (TNFα), interleukin-6 (IL-6), dexamethasone (Dex), and insulin on the mRNA and protein expressions of GPR54 in the MCF7 cell line in vitro.

METHODSMCF7 breasr cancer cells were cultured and treated with different concentrations of LPS (10 and 20 µg/ml), TNFα (20 and 100 ng/ml), IL-6 (10 and 20 ng/ml), Dex (10(-6) and 10(-7) mol/L), and insulin (0.01 and 0.1 IU/L). Those treated with culture fluid only served as controls. The mRNA and protein expressions of GPR54 were measured by real-time PCR and Western blot, respectively, after 6, 24, 48, and 72 hours of treatment.

RESULTSCompared with the blank con- trol, LPS (10 and 20 µg/ml), TNFα (20 and 100 ng/ml), IL-6 (10 and 20 ng/ml), Dex (10(-6) and 10(-7) mol/L), and insulin (0.01 and 0.1 IU/L) significantly increased the expressions of GPR54 mRNA (P < 0.05) and protein (P < 0.05).

CONCLUSIONLPS, TNFα, IL-6, Dex, and insulin evidently increase the expression of GPR54 in the MCF7 cell line, indicating their influence on the function of gonads by regulating the GPR54 level.

Objective:To observe the effect of horse-riding squat exercise plus Governor Vessel-regulating Tuina(Chinese therapeutic massage)therapy on static balance function in patients with stroke.Methods:A total of 176 stroke patients were enrolled as the study subjects and divided into four groups by the random number table method,namely horse-riding squat+Tuina group,horse-riding squat group,Tuina group,and control group,with 44 cases in each group.The control group was treated with rehabilitation balance training.The horse-riding squat+Tuina group,horse-riding squat group,and Tuina group were treated with additional horse-riding squat exercise plus Tuina,horse-riding squat exercise,and Tuina treatment,respectively.Four weeks of treatment was regarded as one treatment course.After 1 treatment course,the balance function of the four groups was compared.Results:After treatment,the ellipse area of motion and the length of motion in all four groups were reduced,and the intra-group differences were all statistically significant(P＜0.05).The difference in the ellipse area of motion before and after treatment in the horse-riding squat+Tuina group and the horse-riding squat group was larger than that in the control group,and the differences were statistically significant(P＜0.05).The difference in the ellipse area of motion before and after treatment in the horse-riding squat+Tuina group was larger than that in the Tuina group,and the difference was statistically significant(P＜0.05).The difference in the length of motion before and after treatment in the horse-riding squat+Tuina group,the horse-riding squat group,and the Tuina group was greater than that in the control group,and the differences were statistically significant(P＜0.05).There was no statistically significant difference in the pairwise comparison between the horse-riding squat+Tuina group,the horse-riding squat group,and the Tuina group(P＞0.05).Conclusion:Horse-riding squat exercise plus Governor Vessel-regulating Tuina therapy can effectively improve the static balance function in patients with stroke.Training the affected lower limb weight-bearing exercise,adjusting the center of gravity distribution,and promoting the mutual balance and coordination between muscle groups may be the mechanism of improving the static balance function.

Objective:To observe the clinical effect of electroacupuncture(EA)combined with exercise therapy on balance function in patients with knee osteoarthritis(KOA). Methods:Seventy patients with KOA were randomly divided into a treatment group and a control group,with 35 cases in each group.The treatment group was treated with EA combined with exercise therapy.EA was applied to Dubi(ST35),Neixiyan(EX-LE4),Xuehai(SP10),Liangqiu(ST34),Yanglingquan(GB34),and Zusanli(ST 36).Exercise therapy(muscle strength training and knee mobility training)was applied after EA.The control group only received the same exercise therapy as the treatment group.The two groups were treated with the same course of treatment,3 times a week for 4 consecutive weeks,12 times in total,and followed up for 1 month.The Pro-Kin254P balance test system was used to measure the balance function parameters at 4 time points,including before treatment,after 1 session of treatment,after 12 sessions of treatment,and at 1-month follow-up after treatment.The visual analog scale(VAS)and the Western Ontario and McMaster Universities osteoarthritis index(WOMAC)scores were recorded. Results:The markedly effective rate and total effective rate in the treatment group were higher than those in the control group(P<0.01).The Romberg area,Romberg length,and VAS scores of the two groups decreased significantly after 1 session of treatment,12 sessions of treatment,and 1 month after treatment,and the differences between different time points in the same group were statistically significant(P<0.01).There were significant differences between the two groups at the same time point(P<0.05).The total WOMAC scores of the two groups after 1 session of treatment,12 sessions of treatment,and 1 month after treatment decreased significantly,and there were significant differences between different time points in the same group(P<0.05),but there was no significant difference between the two groups at the same time point(P>0.05). Conclusion:EA combined with exercise therapy or exercise therapy alone can enhance the balance function,relieve joint pain,and improve joint function in patients with KOA.EA combined with exercise therapy is superior to exercise therapy alone in improving balance function and pain,but the two treatment protocols have similar effects in improving joint function.

Objective To analyze the difference in computed tomography (CT) imaging findings between pulmonary alveolar pneumoconiosis Methods proteinosis (PAP) and occupational pneumoconiosis (hereinafter referred to as ). A total of 44 patients with PAP (PAP group) and 44 patients with pneumoconiosis (pneumoconiosis group) were selected as study subjects using Results convenient sampling method. The CT images of these two groups were comparatively analyzed. The detection rates of - - pulmonary CT pattern changes such as map like performance, ground glass opacity, paving stone sign and sphenoid wing like vs vs changes of pulmonary hilum in the PAP group were higher than those in the pneumoconiosis group (77.3% 0.0%, 75.0% vs vs P 2.3%, 56.8% 0.0%, 18.2% 0.0%, all <0.01); the detection rates of lymphadenopathy and calcification of pulmonary hilum, small pulmonary nodules, emphysema and interlobular septal thickening were lower in the PAP group than those in the vs vs vs vs P Conclusion pneumoconiosis group (34.1% 100.0%, 4.5% 100.0%, 2.3% 45.4%, 0.0% 22.7%, all <0.01). Paving - stone sign and map like performance were most commonly found in the CT imaging of patients with PAP, and it is uncommon in pneumoconiosis. These changes could be used as the CT differential diagnosis of the two diseases.

AIM: To explore the relationship between serum uric acid(SUA)and cystatin C(CysC)levels with diabetic retinopathy(DR).METHODS: A prospective study.A total of 53 non-DR patients with type 2 diabetes mellitus(T2DM; T2DM group)and 83 patients with DR admitted to the hospital between May 2019 and May 2021 were enrolled. In DR patients, there were 47 cases with non-proliferative diabetic retinopathy(NPDR)in NPDR group and 36 cases with proliferative diabetic retinopathy(PDR)in PDR group. A total of 48 healthy people in physical examination center during the same period were enrolled as control group. The serological indexes of all subjects were compared. SUA level was detected by urate oxidase method. The level of serum CysC was detected by immunoturbidimetry. The correlation between serum SUA, CysC and the other serological indexes was analyzed by Spearman. The influencing factors of serum SUA and CysC were analyzed by multivariate linear stepwise regression method. The predictive efficiency of serum SUA and CysC for DR was analyzed by receiver operating characteristic(ROC)curves.RESULTS: The body mass index(BMI)and systolic blood pressure(SBP)in T2DM, NPDR and PDR group were significantly higher than those in control group(all P<0.05). SBP in PDR group was significantly higher than that in T2DM and NPDR group(all P<0.05). The course of diabetes mellitus in NPDR and PDR group was significantly longer than that in T2DM group(all P<0.05), and it was significantly higher in PDR group than in NPDR group(P<0.05). The levels of fasting plasma glucose(FPG), hemoglobin Alc(HbA1c), SUA and CysC in control group, T2DM group, NPDR group and PDR group were gradually increased(all P<0.001). The levels of low-density lipoprotein cholesterol(LDL-C)and triglyceride(TG)in PDR group were significantly higher than those in control group(all P<0.05), while level of high-density lipoprotein cholesterol(HDL-C)was significantly lower than that in control group(P<0.05). The levels of serum SUA were positively correlated with FPG, HbA1c, total cholesterol(TC)and TG levels(rs=0.564, 0.631, 0.513, 0.408, P<0.001), but they were not correlated with HDL-C or LDL-C(rs=-0.061, 0.035, P>0.05). The levels of serum CysC were positively correlated with FPG, HbA1c, TC and TG levels(rs=0.524, 0.692, 0.395, 0.435, P<0.001), but they were not correlated with HDL-C or LDL-C(rs=-0.012, 0.049, P>0.05). FPG, HbA1c, TC and TG were influencing factors of serum SUA and CysC levels(P<0.001). The area under the curve(AUC)in the combined detection of SUA and CysC(0.892, 95%CI: 0.840-0.944, sensitivity:71.1%, specificity: 94.3%), was significantly greater than that of AUC [SUA(0.807, 95%CI: 0.735-0.879, sensitivity: 69.9%, specificity: 75.5%)and CysC(0.763, 95%CI: 0.684-0.841, sensitivity: 69.9%, specificity: 75.5%)] alone(all P<0.05).CONCLUSION: The levels of serum SUA and CysC gradually increase with the aggravation of DR. The combined detection of serum SUA and CysC can improve the diagnostic and predictive efficiency for DR.

The study was performed to examine the enterovirus 71(EV71) VP1 genetic feature and the epidemiology of hand-foot-mouth disease (HFMD) in Xinxiang in 2011. Real-time RT-PCR was used for the detection of Pan-enterovirus, Coxsackievirus A 16(CA16) and EV71 from stool specimens of HFMD. The VP1 region was amplified from 10 EV71 positive samples and the products were sequenced. EV71 genotypes were characterized by homology and phylogenetic tree analyses. Additionally, epidemic data of Xinxiang HFMD in 2011 was analyzed. The results revealed that 73% of the specimens from severe cases were determined as EV71 positive, which was significantly higher than CA16-positive ones (19%) (P < 0.01). Ten EV71 strains isolated in Xinxiang belonged to C4a cluster of sub-genotype C4, with 2.8% nucleotide and 0.9% amino acid sequences divergence among them. At position 170 in VP1 gene, an alanine(A) was predominant in 9 isolates, while a valine(V) residue was observed in one isolate. Compared to the representative C4a strains which were closely related to Xinxiang isolates, the amino acid variations of the pre-dominant Xinxiang strains generally occurred at position 292, threonine --> alanine (T --> A). A total of 1118 HFMD cases were reported in Xinxiang in 2011, and 92% of them were younger than 3 years old; the incidence rate peaked in April and December, suggesting that it is very necessary to strengthen HFMD prevention and control even in cold weather.
