AIM: To compare the measurement of anterior chamber depth(ACD) inclusive of corneal thickness using intrao-cular lens(IOL) master and ultrasound biomicroscopy (UBM) and evaluate the repeatability of each method.METHODS: Two consecutive measurements of ACD were prospectively performed using IOL master and UBM in 60 eyes in 60 individuals. Mean values were compared using the paired t test. For each individual, ACD measure-ments was performed 5 times to estimate the repeatability of each method by a coefficient of variation(CV).RESULTS: The mean ACD was 2.95±0.25mm with the IOL master and 2.96±0.22mm with the UBM. This diffe-rence was not statistically significant (P=0.631).The coefficient of variation (CV) was 0.56%±0.26% and 0.65%± 0.36% in IOL master and UBM, respectively.CONCLUSION: The mean ACD of IOL master was the same as UBM. The repeatability of IOL master is better than UBM.

Objective:To investigate the expression of microRNA-324-5p (miR-324-5p) and transcription factor forkhead box C1 (FOXC1) in glioma and their relationship with the prognosis of patients.Methods:From March 2012 to March 2015, a total of 72 cases of glioma tissues were collected from glioma patients who were admitted to Chongqing Hygeia Tumor Hospital and the People's Hospital of Nanchuan in Chongqing, and 28 cases of normal human brain tissues resected in craniocerebral surgery were also collected. The expressions of miR-324-5p and FOXC1 mRNA were detected by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR), and the expression of FOXC1 protein was detected by immunohistochemistry. Pearson method was used to analyze the correlation between the expressions of miR-324-5p and FOXC1 in glioma tissues; Kaplan-Meier method was used to analyze the survival of patients with glioma; Cox regression analysis was used to analyze the risk factors affecting the prognosis of patients with glioma.Results:FOXC1 protein was mainly located in the cytoplasm of glioma, and its positive expression rate in glioma tissues was 81.94% (59/72), which was significantly higher than that in normal brain tissues [17.86% (5/28)], and the difference was statistically significant ( χ2 = 35.938, P<0.01). Compared with normal brain tissues, the expression of miR-324-5p was down-regulated in glioma tissues (0.62±0.19 vs. 0.98±0.02, t = 9.974, P < 0.05), and the expression of FOXC1 mRNA was up-regulated (1.41±0.29 vs. 0.99±0.02, t = 7.633, P < 0.05). The expressions of miR-324-5p and FOXC1 protein were correlated with the number of primary lesions, differentiation degree, TNM stage and lymph node metastasis of glioma (all P<0.05). Pearson analysis showed that the expressions of miR-324-5p and FOXC1 mRNA were negatively correlated ( r = -0.550, P<0.01). The 5-year overall survival rate of patients in miR-324-5p high-expression group was significantly higher than that of patients in miR-324-5p low-expression group (45.71% vs. 24.33%, χ2 = 6.531, P = 0.011), and the 5-year overall survival rate of patients in FOXC1 protein high-expression group was significantly lower than that of patients in FOXC1 protein low-expression group (30.41% vs. 42.34%, χ2 = 3.631, P = 0.047). Multivariate Cox regression analysis showed that low differentiation, TNM stage Ⅲ-Ⅳ, lymph node metastasis, low expression of miR-324-5p and high expression of FOXC1 protein were independent risk factors for prognosis of glioma patients (all P < 0.05). Conclusions:The expression of miR-324-5p is low and the expression of FOXC1 is high in glioma. They may be involved in the regulation of tumor differentiation and metastasis, and related to the poor prognosis of patients. They may be potential therapeutic targets for glioma.

OBJECTIVETo study the effect of Jiangzhuo Mixture (JZM) on glucose and lipid metabolism, free fatty acid (FFA) and insulin sensitivity index of sodium glutamate (MSG) induced obese rats.

METHODSSixty-four male MSG rats, 8-10 weeks old, were randomly divided into 4 groups equally, the low dose and high dose JZM group were treated respectively with 10 mL/(kg d) and 20 mL/(kg d) JZM, the rosiglitazone (RGZ) group with water solution of RGE 20 mg/(kg d), while the model group fed only with distilled water 10 mL/(kg d) for control, all by gastrogavage for 7 successive weeks. Levels of fasting blood glucose (FBG), triglyceride (TG), cholesterol (TC), and serum fasting insulin (Ins) were measured before and after treatment. Besides, the level of FFA and the proportion of fat weight to body weight (F/B) were measured and insulin sensitivity index (ISI) was calculated after treatment.

RESULTSAfter being treated for 7 weeks, the indexes including TC, FBG, Ins, F/B and FFA were all lower than those in the model group. Compared with before treatment, TC level lowered, FBG and Ins level raised in the two JZM groups and the RGZ group. Comparisons between the three treated group showed a significant lower level of Ins in the RGZ group. Level of ISI was significantly lowered in the 3 groups after treatment (P <0.05), but still higher in the RGZ group than that in the model control group (P <0.05). As for level of FFA, it was 314.81 +/- 110.25 micromol/L in the high dose JZM group and 305.56 +/- 92.33 micromol/L in the RGZ group, which were lower than that in the low dose JZM group (375.00 +/- 219.95 micromol/L, P <0.05).

CONCLUSIONSJZM could decrease the serum levels of TC, FBG, Ins and FFA in MSG rats, and decrease the fat content of organism in rats' growth process. The FFA decreasing action is dose-dependent. But its effect on ISI in MSG rats in the growth stage is insignificant. JZM can not reverse the forming processes of hyperglycemia, hyperinsulinemia, and insulin resistance in MSG rats.

Abstract: Objective　To investigate the distribution and drug resistance of pathogenic bacteria separated from ascites of patients in Children’s Hospital Affiliated to Zhengzhou University from 2015 to 2021, and to provide a basis for rational clinical antimicrobial agents. Methods　Bacterial culture, bacterial identification and drug sensitivity analysis were performed on 1 058 non-duplicate ascites culture specimens from January 2015 to December 2021. The clinica1 and microbiologica1 data were ana1yzed by WHONET 5.6 and SAS 9.4 Results　Of the 1 058 specimens, 586 (55.39%) were positive for pathogenic bacteria, with a total of 781 strains isolated. There was no significant trend of increase or decrease in the positivity rate over different years. Male children (63.99%) were more prevalent than female children. Appendicitis (59.22%) was the most common disease and Escherichia coli was the most common causative bacteria. Among neonates (≤28 d), the bacteria with the highest detection rate were Klebsiella pneumoniae (23.50%) and Enterococcus faecium (23.50%), while among children (>28 d), the highest detection rate was Escherichia coli (35.98%). Gram-negative bacteria accounted for 64.79% of the 781 strains, mainly Escherichia coli (38.28%), Klebsiella pneumoniae (8.58%), and Pseudomonas aeruginosa (5.89%); Gram-positive bacteria accounted for 29.45%, mainly Enterococcus faecium (8.58%), Streptococcus constellatus (2.69%), and Enterococcus avium (2.43%); fungi accounted for 1.66% and anaerobic bacteria accounted for 4.10%. The resistance rates of Escherichia coli to cefoperazone/sulbactam, piperacillin/tazobactam, imipenem and meropenem were 6.02%, 4.35%, 4.35%, and 3.68%, respectively. The resistance rates of Klebsiella pneumoniae to these drugs were 59.70%, 59.70%, 50.75% and 53.73% respectively. Linezolid-resistant strains of Enterococcus faecium were found. Conclusion　Appendicitis is the most common abdominal infection in children, and the distribution of ascites pathogens varies with ages and diseases. The pathogenic bacteria are mainly Gram-negative bacteria, and the drug resistance of Klebsiella pneumoniae was more serious. It is particularly important to use antibiotics correctly and rationally to reduce the emergence of drug resistant bacteria.

OBJECTIVETo study the rules of occurrence and development of TCM syndromes in patients of depression by analysing the population distribution and related factors of it.

METHODSA clinical epidemiologic survey was carried out with the materials collected by the four-diagnostic method from patients of depression to gain the syndrome types of 397 patients through dynamic cluster analysis, factor analysis and TCM syndrome differentiation. The constitution of syndrome types in different population and the relation between TCM syndrome types and the clinical types differentiated by Western medicine of depression was analyzed.

RESULTSSix syndrome types were found in 397 patients with depression. They were, ranging in occurrence order, the Gan-Qi stagnation with mental uneasiness type (108 cases, 27.2%); the Xin-Pi deficiency with dampness retention type (94 cases, 23.7%); the Xin-Gan Qi-stagnation with Phlegm retention type (76 cases, 19.1%); the Xin-Gan Qi stagnation with Jing-Luo disharmony type (57 cases, 14.3%); the Xin-Shen Qi stagnation with collateral obstruction type (34 cases, 8.6%); and the Xin-Gan Qi stagnation with Heat interfering mental type (28 cases, 7.1%). There were statistical significance (P < 0.01) in comparison of the syndrome types constitution among patients of different ages or different Western medicinal types (mild, with or without psychotic symptoms), but no significant difference was shown in that among patients of different sexes, with or without familial history of mental diseases, with monophasic or biphasic, initial or recurrent episode (P > 0.05).

CONCLUSIONThe result obtained in this study is basically in accord with the cognitive rule of TCM theory, it provides a reliable base of syndrome differentiation for treatment.

Objective To evaluate the olfactory functions in patients with Parkinson's disease (PD) with a smell identification test developed for the Chinese population and to examine possible factors contributing to PD patients' olfactory performance.Methods Fifty-five patients with idiopathic and nondementia PD and 55 demographically matched healthy controls (HC) were recruited and their olfactory identification tested using the Chinese Smell Identification Test developed by the Institute of Psychology at Chinese Academy of Sciences.Results Olfactory identification score was significantly lower (t =-6.827,P＜0.01) in the PD group (19.3 ±5.4) as compared with the HC group (26.5 ±5.7).Of all PD patients,63.6％ scored over 1 SD below the age norm.In particular,of those with Hoehn-Yahr ratings between 2 to 3,77.8％ scored over 1 SD below the age norm.Receiver operating characteristic (ROC) curve analysis indicated that a cut-off score of 22.5 on the Chinese Smell Identification Test distinguished between PD patients and HC with a sensitivity of 74.6％ and specificity of 70.9％.Within the PD group,age,education,Hoehn-Yahr rating and Mini-Mental State Examination score were not found to correlate with olfactory performance (all P ＞ 0.05).Conclusion PD patients in China show significant impairment of olfactory identification,which is effectively captured by the Chinese Smell Identification Test.

Objective To investigate the clinical efficacy of scalp acupuncture plus electroacupuncture in treating migraine without aura.Methods Three hundred and twenty-six patients with migraine without aura were randomly allocated to a treatment group of 157 cases and a control group of 169 cases. The treatment group received scalp acupuncture plus electroacupuncture and the control group, medication alone. The Pain Rating Index (PRI) score and the TCM syndrome rating scale score were scored in the two groups of patients before and after treatment. The numbers of taking medicine and the numbers of headache attacks were compared between the two groups of patients during treatment. An analysis was made of factors influencing the therapeutic effect on migraine. Results There were statistically significant differences in the PRI score and the TCM syndrome rating scale score at the end of treatment and at one, two and three months of follow-up compared with before treatment in the two groups (P<0.05). There were statistically significant differences in the PRI score and the TCM syndrome rating scale score at the end of treatment and at one and two months after it between the treatment and control groups (P<0.05). There was a statistically significant difference in the weekly number of taking medicine between the treatment and control groups during treatment (P<0.05). There was a statistically significant difference in the number of headache attacks between the treatment and control groups at two, three and four weeks of treatment (P<0.05). In the treatment group, the therapeutic effect at one, two and three months of follow-up was related to both TCM syndrome type and the VAS score; the therapeutic effect at two months of follow-up was related to the sex; the therapeutic effect at three months of follow-up was related to the educational level.Conclusion Scalp acupuncture plus electroacupuncture is an effective way to treat migraine without aura.

OBJECTIVE: To observe the expression pattern of caspase-3 and HCLS1-associated protein X-1 (HAX-1) at different time after cerebral contusion in rat, and explore the new method for estimating the injury interval. METHODS: The cerebral contusion model was established using adult SD male rats. Then the rats were randomly allocated into 8 groups: 2 h, 6 h, 12 h, 1 d, 3 d, and 7 d after cerebral contusion, sham-operation and normal control. Expression of caspase-3 and HAX-1 protein after cerebral contusion in rat was detected by Western blotting. Laser scanning confocal microscope was used to observe the number of HAX-1 positive cells and TUNEL-stained cells after cerebral contusion. RESULTS: The expression of caspase-3 increased parallelly with the time after cerebral contusion and reached the peak value on 3 d. The expression of caspase-3 decreased gradually and still maintained a high level expression on 7 d (P < 0.05). The expression of HAX-1 positive cell went up after injury, and reached the peak value at 6 h (P < 0.05), then turned down gradually after 12 h and went out of detection after 3 d. The number of TUNEL-stained cells increased obviously at 2 h and reached the peak value on 3 d. The number of TUNEL-stained apoptotic cells decreased gradually and still maintained a high level expression on 7 d (P < 0.05). CONCLUSION The expression of caspase-3 and HAX-1 after cerebral contusion has time sequential regularity, which may provide new evidence for forensic diagnosis of cerebral contusion interval.

Objective To study the balance function of normal persons and to explore the differences in gender and age groups.Methods Forty parameters of 445 normal persons(16-70 years old, 205 of male, 240 of female ) were detected by static posturography while they were in seat, double foot standing with opening and closing eyes, and single foot standing with opening eyes. The results of male and female, standing with opening eyes and closing eyes, left foot standing and right foot standing were compared.Results Everyone's center of gravity was distributed in A zone while they were in seat. At standing with opening eyes and closing eyes, the center of gravity in A zone were in 429 subjects( 96.4%) and 436 subjects( 98.0%). Most parameters showed significant difference between the women and the men, opening eyes and closing eyes, left foot standing and right foot standing, different age groups. The stability in closing eyes was better than that in opening eyes, right foot standing was better than left foot standing. Most values of 20—39 years old group were the best, 70—79 years old group were the worst.Conclusion Static posturography can evaluate human balance function objectively and quantitatively. The stability is related to age and gender. To judge the balance function, the subject's age and sex must be taken into account.
