Objective Motility is an important physiological characteristic of a mature sperm.Nerve growth factor(NGF) is a protein essential for the development,maintenance and survival of the peripheral and central nervous systems.NGF and its receptors TrkA and p75 are widely expressed in the testis,accessory reproductive organ,and the epididymal sperms.In the present study,we investigated the role of NGF on human sperm motility.Methods Use 0.1,1 and 10 μmol/L concentrations of NGF,on sperm motility study to investigate the optimal concentration.Use CASA to detect Sperm motility changes every 10 minutes in an hour after 10 μmol/L NGF was added to the semen.Results The parameters of sperm motility increased after NGF incubation had significant difference, in particular,VAP,VSL,VCL,BCF and LIN mean were significantly increased more than 32%.MAD,STR,ALH and WOB mean had no notable difference.Furthermore,NGF promotes the sperm motility in a time- and dose- dependent manner.In addition,the enhancement of NGF on sperm motility was more stronger than those of sperm culture medium.Conclusion Our findings suggest that NGF plays a promoted role in human sperm motility.

Objective To study the clinical features of acute limited neck motion in children and its differential diagnosis, and to improve doctors' awareness and the early diagnosis of the disease.Methods A total of 420 patients with acute limited neck motion as the chief complaint and atlantoaxial rotary subluxation as the first diagnosis between January 2005 and January 2014 in Nanjing Children's Hospital Affiliated to Nanjing Medical University were enrolled.The clinical manifestations, imaging and consultation data of the 420 patients were retrospectively analyzed.Results There were totally 248 male patients and 172 female patients.The ages ranged from 2 to 14 years old(the mean age was 7.2 years old) ,the course ranged from 2 hours to 2 days.Among 420 patients,353 patients were diagnosed as atlantoaxial rotatory subluxation.Forty-two patients were diagnosed as cervical intervertebral disc calcification.Seven patients were diagnosed as Tourette syndrome.Four patients were diagnosed as intracranial tumors.Three patients were diagnosed as cervical eosinophilic granuloma.Two patients were diagnosed as cervical spinal tuberculosis.Two patients were diagnosed as viral encephalitis.Two patients were diagnosed as benign paroxysmal torticollis.Two patients were diagnosed as Kawasaki disease.One patient was diagnosed as neuroblastoma.One patient was diagnosed as hemophilia A.One patient was diagnosed as drug adverse reaction of metoclopramide.According to Fielding clinical classification,204 patients were type Ⅰ, 122 patients were type Ⅱ,21 patients were type Ⅲ, and 6 patients were type Ⅳ.Conclusions Based on disease distribution of acute limited neck motion in children, atlantoaxial rotatory subluxation seems to be the predominant while non-atlantoaxial rotatory subluxation is not uncommon.Differential diagnoses should be considered to avoid misdiagnosis.For atlantoaxial rotatory subluxation, conservative treatment including continuous mandible occipital belt traction and brace has been proved to be very effective methods.

OBJECTIVE:To explore the effects of inhaled budesonide on the efficacy and related indexes of patients with acute bronchitis. METHODS:102 patients with acute bronchitis were randomly divided into control group and observation group. Control group was given 100 mg/(kg·d) Cefotaxime sodium injection,adding into 150 ml 0.9% Sodium chloride injection intravenously by 2 times,as well as sedation,oxygen inhalation,rehydration,correcting acid-base balance and other conventional treatment;ob-servation group was additionally given 2 ml Inhaled budesonide suspension,twice a day. The treatment course for both groups was 7 d. Clinical efficacy,erythrocyte immune complex rosette(E-ICR),high-sensitivity C-reactive protein(hs-CRP),peak expiratory flow rate(PEF),forced vital capacity(FVC),1 second forced exhaled volume(FEV1),time of body temperature returned to nor-mal,cough disappearance time,rale disappearance time before and after treatment,and incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,time of body temperature returned to normal, cough disappearance time and rale disappearance time were significantly shorter than control group,the differences were statistically significant(P<0.05). Before treatment,there were no significant differences in the E-ICR and hs-CRP levels,PEF,FVC and FEV1 between 2 groups(P>0.05). After treatment,E-ICR and hs-CRP levels were significant-ly lower than before,and observation group was lower than control group,PEF,FVC and FEV1 were significantly higher than be-fore,and observation group was higher than control group,the differences were statistically significant(P<0.05). And there were no adverse reactions during treatment. CONCLUSIONS:Based on conventional treatment,inhaled budesonide has obvious efficacy in the treatment of acute bronchitis,and it can reduce E-ICR and hs-CRP,improve pulmonary functions,with good safety.

Abstract: Objective　To understand the contamination status, drug resistance, virulence gene carrying status, and molecular typing characteristics of Vibrio parahaemolyticus (VP) in aquatic products sold in Nanchang City. Methods　A total of 170 commercial crayfishes, freshwater fish frogs and related smears samples were collected from various farmers' markets in Nanchang from March to September 2021. The strains of V. parahaemolyticus were detected and isolated from the samples. Antibiotic resistance test, virulence gene test, and pulsed-field gel electrophoresis (PFGE) molecular typing analysis were carried out. Results　Among the collected samples, V.parahaemolyticus was only isolated from crayfish and crayfish smear samples, with a total of 35 strains of VP isolated. No V.parahaemolyticus strain was isolated from other freshwater fish, frogs, and their smear samples. Among the 17 common antibiotics tested, only two trains showed resistance to ampicillin, and one strain to streptomycin, , and all were sensitive to other antibiotics; all 35 strains of V. parahaemolyticus carried the gene, but only one strain carried the heat-resistant related hemolysin gene trh, and no direct heat-resistant hemolysin gene tdh positive strain was found; PFGE pattern clustering showed that there was no strain with the same PFGE pattern, and there was no obvious dominant cluster among these strains, and their genetic relationship was relatively distant. Conclusions　The contamination of V. parahaemolyticus in small and medium-sized crayfish sold in the market in Nanchang City is relatively serious. The V. parahaemolyticus isolates in these polluted crayfish generally do not carry key virulence genes such as tdh, are sensitive to common antibiotics, and only have low-level resistance to ampicillin and streptomycin. PFGE pattern clustering showed that V. parahaemolyticus does not have no obvious dominant cluster, and these strains have rich genetic diversity, indicating that they may have different sources.

Objective To study the expression of KAI1 and CD40 in gastric cancer and their correlation with clinicopathologic features and prognosis.Methods The expression of KAI1 and CD40 of 64 gastric cancer tissues was examinated by S-P immunohistochemieal methods.Results The overall positive rate of KAI1 was 22% in gastric cancer.Expression of KAI1 was positively related to the degree of tumor differentiation,it was negatively related to invasion depth and lymph node metastasis and the tumor clinical stage.The 5-year survival rate of cases with positive expression of KAII was significantly higher than that of cases with negative expression(X~2=42.426,P=0.000).The expression rate of CD40 in gastric cancer tissue was 34%.The expression of CD40 was significantly correlated with metastasis and clinical stage of gastric cancer.The 5-year survival rate of cases with positive expression of CD40 was significantly lower than that of cases with negative expression(X~2=4.841,P=0.028).There is no relationship between KAI1 and CD40 expression in gastric cancer.Conclusion KAI1 is associated with gastric cancer differentiation,invasion and metastasis.CD40 status helps to evaluate metastasis,and predict prognosis of gastric cancer.

Objective To study the clinical features and to improve the treatment on the elderly patients with brain tumor.Methods Retrospective analysis of 163 cases with brain tumor which had been confirmed by CT,MRA or pathology.Results Of all the 163 cases,121 were located in supratentorium,most of which were meningiomas and gliomas.Most patients(129 cases)had comorbidity.After operation,symptoms disappeared or obviously improved in 126 cases,moderately improved in 19 cases,and did not changed in 6 patients.Twelve cases died after operation in a month, in which 9 patients were over 75 years old.The death rate of operation was 6.1%.Conclusions It is important to know the atypical manifestation of brain tumor in the elderly,which may prevent clinical misdiagnosis and mistherapy.The perioperative management is indispensable to the prognosis of the patients.The choice of operation and medication should be in individualized.

Objective:To investigate the prognostic value of preoperative red blood cell distribution width (RDW) for hepatocellular carcinoma (HCC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 1 025 HCC patients who were admitted to three medical centers (586 in the First Affiliated Hospital of Xi'an Jiaotong University, 248 in the Second Affiliated Hospital of Xi'an Jiaotong University and 191 in the Qinghai University Affiliated Hospital) between April 2002 and August 2017 were collected. There were 809 males and 216 females, aged (54±11)years, with a range from 16 to 83 years. The average coefficient of variation of RDW (RDW-CV) of 1 025 patients was 14.3%. Of 1 025 patients, 347 cases had high RDW of RDW-CV >14.3%, and 678 had low RDW of RDW-CV ≤14.3%. Observation indicators: (1) clinico-pathological data of HCC patients; (2) influencing factors for prognosis of HCC patients; (3) follow-up and survival. (4) stratified analysis of independent influencing factors. Follow-up was performed by outpatient examination, telephone interview or internet interview to detect postoperative survival of patients up to October 2017. Measurment data with normal distribution were represented as Mean±SD, and measurment data with skewed distribution were described as M (range). Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. The Graphpad Prism 7.0 was used to draw survival curves, and Log-rank test was used for survival analysis. Univariate and multivariate analyses were performed using the COX proportional hazard model. Results:(1) Clinicopathological data of HCC patients: cases with age ≤70 years or >70 years, cases without cirhhosis or with cirhhosis , cases of Child-Pugh grade A or Child-Pugh grade B or C, cases with the level of alpha fetoprotein (AFP) ≤200 μg/L or >200 μg/L, cases with single tumor or multiple tumors were 313, 34, 152, 186, 161, 53, 158, 143, 186, 109 for high RDW patients, versus 641, 37, 359, 310, 415, 48, 367, 227, 547, 131 for low RDW patients, respectively, showing significant differences in above indicators between the two groups ( χ2=6.709, 6.787, 23.906, 7.114, 34.375, P<0.05). (2) Influencing factors for prognosis of HCC patients: results of univariate analysis showed that age, Child-Pugh grade, AFP, RDW-CV, tumor diameter, the number of tumors were related factors for prognosis of patients ( hazard ratio=1.388, 1.432, 1.534, 1.455, 2.813, 1.505, 95% confidence interval as 1.004-1.920, 1.086-1.887, 1.263-1.864, 1.211-1.748, 2.293-3.450, 1.173-1.932, P<0.05 ). Results of multivariate analysis showed that age, RDW-CV, tumor diameter and the number of tumors were independent factors for prognosis of patients ( hazard ratio=1.020, 1.340, 2.427, 1.438, 95% confidence interval as 1.007-1.032, 1.027-1.749, 1.801-3.272, 1.057-1.956, P<0.05). (3) Follow-up and survival: 1 025 patients were followed up for 1-124 months, with a median follow-up time of 25 months. The median survival time was 23 months for high RDW patients, versus 44 months for low RDW patients, showing a significant difference in the overall survival between the two groups ( χ2=11.640, P<0.05). (4) Stratified analysis of independent influencing factors: the results of stratified analysis of 3 independent influencing factors including age, tumor diameter and the number of tumors showed that in the 954 patients with age ≤70 years, the median survival time was 25 months for high RDW patients, versus 48 months for low RDW patients, showing a significant difference in the overall survival between the two groups ( χ2=14.030, P<0.05). In the 71 patients with age >70 years, the median survival time was 11 months for high RDW patients, versus 29 months for low RDW patients, showing no significant difference in the overall survival between the two groups ( χ2=0.933, P>0.05). In the 459 patients with tumor diameter ≤5 cm, the median survival time was 44 months for high RDW patients, versus 76 months for low RDW patients, showing a significant difference in the overall survival between the two groups ( χ2=8.660, P<0.05). In the 487 patients with tumor diameter >5 cm, the median survival time was 14 months for high RDW patients, versus 18 months for low RDW patients, showing no significant difference in the overall survival between the two groups ( χ2=2.950, P>0.05). In the 733 patients with single tumor, the median survival time was 20 months for high RDW patients, versus 48 months for low RDW patients, showing a significant difference in the overall survival between the two groups ( χ2=13.530, P<0.05). In the 240 patients with multiple tumors, the median survival time was 15 months for high RDW patients, versus 20 months for low RDW patients, showing a significant difference in the overall survival between the two groups ( χ2=6.820, P<0.05). Conclusions:Preoperative RDW can be used as a predictive index for prognosis of HCC patients, and patients with high RDW have poorer prognosis. RDW have better predictive value in patients with age ≤70 years or tumor diameter ≤5 cm.

BACKGROUNDTo study oxidative stress in patients with chronic hepatitis B.

METHODSMalondialdehyde (MDA), total anti-oxidative ability and ascorbic acid were measured as markers of oxidative stress in 30 patients with chronic hepatitis B, besides HBV DNA and ALT.

RESULTSMDA was significantly higher in patients with hepatitis B than the controls (P less than 0.05). Ascorbic acid was significantly higher in patients with normal ALT than the controls (P less than 0.01). MDA was significantly higher in patients with increased ALT than the controls and in patients with normal ALT. MDA was significantly positively correlated with ALT (r=0.61), and ascorbic acid was significantly negatively correlated with ALT (r=-0.64) in patients with hepatitis B. No significant relationship was found between HBV DNA and other indices of oxidative stress. No significant difference in total anti-oxidative ability was found among all groups.

CONCLUSIONThere was a disturbance between oxidative stress and anti-oxidative ability in patients with chronic hepatitis B. In patients with increased ALT, oxidative stress became high. In patients with normal ALT, oxidative stress level was low. The indices of oxidative stress should be detected in patients with hepatitis B, in addition to HBV markers.

The present study was designed to investigate the function and mechanism of high-frequency stimulation (HFS) of the parafascicular nucleus (PF) used as a therapeutic approach for Parkinson's disease (PD). PD rat model was built by injecting 6-hydroxydopamine (6-OHDA) into the substartia nigra pars compacta of adult male Sprague-Dawley rats. Using the ethological methods, we examined the effect of electrical stimulation of PF on the apomorphine-induced rotational behavior in PD rats. Moreover, Electrophysiological recordings were made in rats to investigate the effects of electrical stimulation of PF on the neuronal activities of the subthalamic nucleus (STN) and the ventromedial nucleus (VM). Our results showed that one week after HFS (130 Hz, 0.4 mA, 5 s) of PF, there was significant improvement in apomorphine-induced rotational behavior in PD rats. HFS of PF caused an inhibition of the majority of neurons (84%) recorded in the STN in PD rats. The majority of cells recorded in the VM of the thalamus responded to the HFS with an increase in their unitary discharge activity (81%). These effects were in a frequency-dependent manner. Only stimulus frequencies above 50 Hz were effective. Furthermore, employing microelectrophoresis, we demonstrated that glutamatergic and GABAergic afferent nerve fibers converged on the same STN neurons. These results show that the HFS of PF induces a reduction of the excitatory glutamatergic output from the PF which in turn results in deactivation of STN neurons. The reduction in tonic inhibitory drive from the basal ganglia induces a disinhibition of activity in the VM, a motor thalamic nucleus. In conclusion, the results suggest that HFS of PF may produce a therapeutic effect in PD rats, which is mediated by the nuclei of PF, STN and VM.
