Objective　To investigate the expression differences of serum endothelial nitric oxide synthase (NOS3) and glial cell-derived neurotrophic factor (GDNF) in patients with arteriosclerotic cerebral infarction and their role in the prognosis of patients.Methods　A total of 126 patients with atherosclerotic cerebral infarction admitted to our hospital from January 2021 to January 2022 and 130 healthy people in the same period were selected.Patients were divided into groups according to infarct volume,dysfunction and prognosis,and serum NOS3 and GDNF levels were compared between different groups.ROC curve was used to analyze the predictive value of NOS3 and GDNF for poor prognosis.Results　The proportion of diabetes and hypertension in patients with atherosclerotic cerebral infarction increased,and the serum levels of NOS3 and GDNF decreased (P<0.05).There was no significant difference in the levels of NOS3 and GDNF among patients with different infarct volumes (P>0.05).The levels of NOS3 and GDNF in mild dysfunction group,moderate dysfunction group and severe dysfunction group decreased successively (P<0.05).The AUC of NOS3 and GDNF levels in predicting poor prognosis were 0.858 and 0.779,respectively.Conclusion　The serum levels of NOS3 and GDNF in patients with atherosclerotic cerebral infarction are decreased,and their levels are related to the degree of neurological impairment and prognosis of patients,which is expected to be a biological indicator to evaluate the prognosis of patients.

Objective To investigate the efficacy and security of noninvasive ventilator assisted ventilation combined with morphine in treating acute left heart failure.Methods Sixty patients suffering acute left heart failure were divided into two groups:conventional therapy group (thirty cases using morphine and other medicine) and combined group (thirty cases using noninvasive ventilator assisted ventilation combined with morphine).Observe and record clinical results for blood pressure,heart rate,respiratory rate,blood gas analysis,left ventricular ejection fraction (LVEF) as well as occurrence rate of remission time and adverse reaction before treatment,one hour after treatment and remission respectively.Results Clinical results for blood pressure,heart rate,respiratory rate,blood gas analysis,left ventricular ejection fraction (LVEF) have improved after treatment,all clinical indexs have improved obviously except for partial pressure of carbon dioxide in combined group.The difference was significant (P ＜ 0.05) ; Remission time in combined group (6.20 ± 4.12 hours) was shorter than morphine group (8.67 ± 5.28) hours,which has statistically difference (P ＜ 0.05).But occurrence rate of adverse reaction and complication raised slightly in combined group (43.3％ vs.40％).Conclusions Noninvasive ventilator assisted ventilation combined with morphine can relieve clinical symptoms promptly in acute left heart failure,improve prognosis,it is a effectively and safety therapeutic measures.

OBJECTIVE： To investigate the effects of rosuvastatin on in-stent restenosis in middle-aged patients with acute coronary syndrome（ACS）after percutaneous coronary intervention （PCI）. METHODS： Totally 400 middle-aged ACS patients underwent PCI were selected from Xuchang Central Hospital during Mar. 2016 to Apr. 2017， and then divided into control group and observation group according to random number table， with 200 patients in each group. Both groups were given conventional drugs for secondary prevention of coronary heart disease. Control group were given Clopidogrel hydrogen sulfate tablets 75 mg， once a day+Aspirin enteric-coated tablets 100 mg， once a day+Atorvastatin calcium tablets 20 mg， once at bed time every day orally after PCI. Observation group was given Clopidogrel hydrogen sulfate tablets 75 mg， once a day+Aspirin enteric-coated tablets 100 mg， once a day+Rosuvastatin calcium tablets 10 mg， once at bed time every day orally after PCI. Both groups were treated for consecutive 12 months. The serum levels of TG， TC， LDL-C， hs-CRP and IL-35 were recorded in 2 groups before surgery， 1， 3， 6 and 12 months after surgery； in-stent minimum lumen diameter （MLD） was observed immediately after surgery and 12 months after surgery. The occurrence of in-stent restenosis， major adverse cardiovascular events （MACE） and adverse drug reaction （ADR） were recorded. RESULTS： Totally 14 patients dropped out from control group and 18 from observation group， and 368 patients completed the study. Before surgery and immediately after surgery， there was no statistical significance in the serum levels of TG， TC， LDL-C， hs-CRP IL-35 or MLD （P＞0.05）. One day after surgery， the levels of hs-CRP were increased significantly in 2 groups， compared with before surgery （P＜0.05）. One， three， six and twelve months after surgery， the serum levels of TG， TC， LDL-C and hs-CRP were decreased significantly in 2 groups， while the levels of IL-35 were increased significantly， compared with before surgery； and the serum levels of TG and TC （1 and 3 months after surgery）， LDL-C （3 and 6 months after surgery） and hs-CRP （1 month after surgery） in observation group were significantly lower than control group； the level of IL-35 in observation group （1 month after surgery） was significantly higher than control group （P＜0.05）. Twelve months after surgery， MLDs of 2 groups were decreased significantly， and observation group was significantly higher than control group （P＜0.05）. There was no statistical significance in the incidence of in-stent restenosis or the total incidence of MACE and ADR between 2 groups after surgery （P＞0.05）. CONCLUSIONS： Rosuvastatin can effectively improve the levels of blood lipid and inflammatory factor in meddle-aged patients with ACS after PCI， and its effect is better than that of atorvastatin. The drug can delay in-stent restenosis after PCI in these patients， which is better than the effect of atorvastatin. At the same time， rosuvastatin can not increase the risk of MACE and ADR with good safety.

The ratio of Escherichia coli producing extended spectrum beta lactamases (ESBLS)were 13.76%.The ratio of Methicillin resistant Staphylococcus aureus (MRSA)and Methicillin resistant coagulase negative Staphylococcus (MRCNS)were 27.27%and 66.25% respectively.Mycoplasma was most sensitive to minocycline,doxycycline.Conclusion Mycoplasma in-fection was the first,followed by bacteria.clinical should strengthen the surveillance of pathogen infection,and rational use of antibiotics according to the results of drug sensitive test.

OBJECTIVES: To explore the forensic pathological characteristics of corpses in wells, and to summarize the differences in corpses between homicide and suicide, so as to provide references for forensic analysis of such cases. METHODS: Data of 52 corpses found in wells （51 cases） in Xuchang, Henan Province from 2004 to 2016 were retrospectively collected, and descriptive statistics were performed on the dead individuals, time of death, wells, autopsies, and diatom testings. RESULTS: The proportion of males and females in the 52 corpses was 1∶2.5, and 42 people were at the age of >20-50 years （80.8%）. The accuracy of the death time inference were 75.0% and 54.2% within 8 d and 8 d or more after the actual death time, respectively. Most of the wells （84.3%） were small ones with big wellhead diameters of 60-100 cm. The death causes in homicide cases were mainly mechanical injury and suffocation （90.3%） with heads downwards （58.1%）, but that in suicide cases was mostly drow-ning （85.0%） with heads upwards （65.0%） and body surface abrasions （95.0%）. CONCLUSIONS Cases of corpses in wells should be comprehensively analyzed according to scene inspections, autopsies, and auxi-liary tests combined with inspection results.

OBJECTIVES: To investigate the therapeutic effect of recombinant human growth hormone (rhGH) on children with growth hormone deficiency (GHD) and different pituitary developmental conditions. METHODS: A prospective study was performed on 90 children with GHD who were admitted to Xuchang Maternity and Child Health Hospital from June 2020 to December 2021. According to pituitary height on the median sagittal plane, they were divided into three groups: pituitary dysplasia group (n=45), normal pituitary group (n=31), and enlarged pituitary growth group (n=14). The changes in body height, growth velocity, height standard deviation score and serum levels of insulin-like growth factor binding protein-3 (IGFBP-3) and insulin-like growth factor-1 (IGF-1) were examined after treatment in the above three groups, and the differences of the above indices before and after treatment were compared among the three groups. RESULTS: After treatment, all three groups had significant increases in body height, growth velocity, height standard deviation score, and the serum levels of IGFBP-3 and IGF-1 (P<0.05). Compared with the normal pituitary group, the pituitary dysplasia group and the enlarged pituitary growth group had significantly higher values in terms of the differences in body height, growth velocity, height standard deviation score, IGF-1, and IGFBP-3 before and after treatment (P<0.05). There was no significant difference in the incidence rate of adverse reactions among the three groups (P>0.05). CONCLUSIONS In GHD children with different pituitary developmental conditions, rhGH can promote bone growth and increase body height, especially in children with pituitary dysplasia and pituitary hyperplasia, with good safety.

Background: Due to the unavailability of an effective vaccine or antiviral drug against the African swine fever virus (ASFV), rapid diagnosis methods are needed to prevent highly contagious African swine fever. Objectives: The objective of this study was to establish the ladder-shape melting temperature isothermal amplification (LMTIA) assay for the detection of ASFV. Methods: LMTIA primers were designed with the p72 gene of ASFV as the target, and plasmid pUC57 was used to clone the gene. The LMTIA reaction system was optimized with the plasmid as the positive control, and the performance of the LMTIA assay was compared with that of the commercial real-time polymerase chain reaction (PCR) kit in terms of sensitivity and detection rate using 200 serum samples. Results: Our results showed that the LMTIA assay could detect the 10 4 dilution of DNA extracted from the positive reference serum sample, which was the same as that of the commercial real-time PCR kit. The coincidence rate between the two assays was 100%. Conclusions The LMTIA assay had high sensitivity, good detection, and simple operation. Thus, it is suitable for facilitating preliminary and cost-effective surveillance for the prevention and control of ASFV.

Objective: To evaluate the iodine nutritional status of children and pregnant women in non-high iodine areas with different water iodide levels that supplied with standard iodized salt. Methods: In 2016-2018, after excluding high iodine towns, in each county 5 townships were selected according to the east, west, south, north, and middle orientation. If the township was concentrated in water supply, 1 sample of peripheral water was collected; If the water supply was dispersed, collected 10 water well samples in each village to test the water iodine content. And 40 children aged 8-10 years and 20 pregnant women were extracted to collect urine samples and household salt samples, and iodine of urine and salt samples were tested. Children's thyroid volume was examined by B-mode ultrasound. The differences of urinary iodine and child goiter rates among children and pregnant women in different water iodine content areas were analyzed. Results: A total of 1 282 water samples were collected from 30 townships in Xuchang City, and the median water iodine range of townships was 0.80-94.70 μg/L. A total of 1 258 children aged 8-10 years were investigated, and the median salt iodine content of children homes was 26.8 mg/kg, ranging from 0 to 60.9 mg/kg; the median urinary iodine level of children was 211.5 μg/L, and the range was 8.3-833.6 μg/L; 39 children with goiter were examined, and the children's goiter rate was 3.10%. A total of 616 pregnant women were investigated, and the median salt iodine content of pregnant women's homes was 26.9 mg/kg, ranging from 0 to 88.0 mg/kg; the median urinary iodine level of pregnant women was 182.2 μg/L, ranging from 9.7 to 609.6 μg/L. In the areas of the median water iodine 0-< 10, 10-< 50 and 50-100 μg/L, the median urinary iodine of 8-10 years old children were 202.6, 204.0, 320.5 μg/L, respectively, the difference between the three was statistically significant (H=79.89, P < 0.01). And the area of 50-100 μg/L was significantly higher than 0-< 10.0, 10-< 50 μg/L areas (P < 0.01); the children's goiter rate of the three areas was 1.58% (10/634), 4.40% (22/500) and 5.65% (7/124), respectively; the median urinary iodine of pregnant women of the three areas respectively was 177.0, 180.9 and 238.0 μg/L, and the 50-100 μg/L areas was higher than 0-< 10, 10- < 50 μg/L areas(P < 0.01). Conclusion The current standard iodized salt in non-high iodine areas in Xuchang City is basically suitable for most children and pregnant women with iodine nutrition, but the iodine nutrition of children with water iodine greater than 50 μg/L is excessive.

Objective To investigate the correlation of HCV-RNA with detection indexes HCV-Ab and HCV-cAg in its clini-cal application effect among patients with hepatitis C.Methods HCV-cAg and HCV-Ab in 140 cases of HCV-RNA were detected by enzyme linked immunosorbent assay in cases of PCR,which were detected by real-time fluorescence quantitative PCR.Results 127 cases in 140 cases of HCV-RNA positive serum were HCV-cAg positive,in line with the rate of 90.71%,and the cases of 110 HCV-Ab positive,in line with the rate of 78.57%.The positive detection rate of HCV-cAg with different HCV-RNA concentration was increased with the increase of HCV virus content,and the serum of different HCV-RNA concentration had no significant changes in HCV-Ab detection results.Conclusion The detection results of HCV-cAg had a high coincidence rate with HCV-RNA.Therefore detection of HCV-cAg can be as a complementary detec-tion of HCV-Ab,as the window period of HCV infection and infection in immunocompromised persons screening provides a simple,inexpensive method.At the same time it provides rapid screening for HCV infection provide diagnostic basis for those basic medical units who do not have the conditions for detection of HCV-RNA.
