Objective To study the effects of semiconductor laser irradiation and high voltage static electric fields on small vessel damage in diabetic rats.Methods Fifty healthy male Wistar rats were randomly divided into two groups:8 rats in a normal group and 42 in a diabetic model group.The diabetic models were created by intrape- ritoneal injection of streptozocin.The diabetic model rats were randomly divided into four subgroups:a diabetes group,a semiconductor laser treatment group,a high voltage static electric field treatment group and a comprehensive treatment group receiving combined semiconductor laser and high voltage static electric field exposure.The rats in each treatment group were subjected to the corresponding intervention.After 20 days of treatment,the venous blood, kidney tissue and myocardium tissue of the rats were collected,and the concentrations of blood glucose,insulin,en- dothelin and tissue were detected.Results Compared with the normal group,a significant increase in blood glu- cose and endothelin was observed in the diabetic model group,along with significantly decreased blood insulin and significant small vessel endothelium proliferation in the kidney tissue.Compared with the diabetes group,endothelin levels were significantly lower in all 3 treatment groups,and blood insulin was also higher in the comprehensive treat- ment group.Conclusion There were severe abnormalities in blood glucose,insulin and endothelin as well as mild impairment of small vessel endothelium proliferation in the diabetic rats.Semiconductor laser and high voltage static electric field exposure have a role in treating and preventing these conditions in diabetic rats.

Objective To investigate the therapeutic action of Taurine in patients with cerebral infarction(CI)induced by hyperhomocysteinemia(Hhcy).Methods The 100 CI patients induced by Hhcy were randomly divided to two therapy groups.One group was administered Taurine,the other group was administered Folacin combined with Vitamine B12 for 8 weeks.Before and after treating,the serum levels of homocysteic acid(Hcy),Folacin and Vitamine B12 were detected,NIHSS and BI were evaluated.Results The serum levels of Hcy were significantly decreased after administering in both two groups(all P

OBJECTIVETo determine the effects of nerve growth factor (NGF) on proliferation of hepatic stellate cells (HSCs) and investigate the related molecular mechanism.

METHODSAfter incubating cultured HSCs for 24 h with different concentrations of NGF (100, 200 or 400 ng/mL), the cell proliferation was observed by XTT colorimetric assay and cell cycle was detected by flow cytometry. Morphological changes in response to a 24 h exposure to 100 ng/mL NGF were observed by transmission electron microscopy.

RESULTSNGF significantly inhibited HSC proliferation (P less than 0.05) in a dose-independent manner. The optical densities of the XTT colorimetric assay were 0.66+/-0.03 for 100 ng/mL NGF, 0.69+/-0.03 for 200 ng/mL NGF, and 0.66+/-0.03 for 400 ng/mL NGF, all of which were significantly lower than that of the control group (0.73+/-0.01; P less than 0.05). All concentrations of NGF led to significantly higher numbers of HSCs in the G2 phase (100 ng/mL: 14.83+/-5.41%, 200 ng/mL: 14.73+/-2.50%, and 400 ng/mL: 14.87+/-2.06%), compared to that detected in the control group (7.47+/-4.39%; P less than 0.05). Twenty-four hours of exposure to 100 ng/mL NGF caused morphological changes indicative of apoptosis.

CONCLUSIONNGF inhibits the proliferation of HSCs, possibly by arresting the cells in the G2 phase of the cell cycle. NGF-inhibited cells may also undergo apoptosis.

Objective To investigate the prognostic sequelae in neontes with hypoxic-ischemic encephalopathy (HIE) and ven-tricnlar dilatation.Methods Seventy-six full term newborns infants with HIE were followed up at the age from 3 to 19 months after therapy. Twenty-five infants among them were followed up by telephone in the epidemic period of SARS.Results Among 76 infants of 88 newborn infants with HIE(84.6%), 73 infants were normal (96.1% ). 1 infant had cerebral palsy (1.3%), 2 infants died (2.6 %).Among 39 cases with mild HIE, none of them had cerebral sequelae; among moderate HIE. 1 infant had cerebral palsy (2.9%) 1 infant died (2. 9 %), interlenkin-4 among severe HIE 50 % died (P00.5 The poor outcome of HIE in those infants were related to intrauterine growth retardation,severe birth asphyxia;and inadequate treatment.Cranial ultra-sonography of 49 infants were done on follow-up,and 12 of them (24.5 % ) had ventricular dilatations, which appeared after birth with 6 infants. Others occurred on follow-up with 1 infant had cerobral palsy,all ventricular dilatations recovered to normal at 12- 19 months except the cerebral palsy.Conclusions The poor outcome of HIE depends on the infants with intranterine growth relarda-tion,severe birth asphyxia and inadequate treatment.The prognosis of transient ventrealar ddatation are good except cerebral palsy.J Appl Clin pediatr,2004,19(12) : 1045- 1047

OBJECTIVETo observe the effects of Huganjiexian decoction on rat hepatic fibrosis and the creation of cytokines.

METHODSRat hepatic fibrosis was induced by intraperitoneally injection of carbon tetrachloride. At the same time, these rats were treated with different dosages of Huganjiexian decoction. Sho-saiko-to compound treating group and Fufangbiejiarangan Tablets treating group were used as positive controls. After twelve weeks, all rats were executed. Histopathologic changes were observed after H.E and Masson stainings. The expression of collagen type I, collagen type III, TGF-beta 1 and PDGF-BB in liver were detected by immunohistochemical staining.

RESULTSCompared with fibrotic group, hepatic fibrosis in decoction groups was significantly improved. In decoction groups, levels of collagen type I, collagen type III, TGFbeta1 and PDGF-BB were decreased, especially in the low-dose curcumin group. The TGF-beta 1 positive percentage were 7.56%+/-2.18%, 29.25%+/-7.84%, 13.54%+/-4.15%, 21.82%+/-6.64%, 20.06%+/-7.14%, 13.78%+/-4.35%, 12.75%+/-3.98% in liver tissues from normal group, model group, low, middle, high curcumin, Sho-saiko-to compound and Fufangbiejiarangan Tablets treating groups respectively (P less than 0.05); while the PDGF-BB positive percentage were 1.68%+/-0.41%, 11.70%+/-2.28%, 3.65%+/-0.76%, 5.24%+/-1.04%, 6.37%+/-1.12%, 4.16%+/-0.61%, 3.38%+/-0.56% in liver tissues from those groups respectively (P less than 0.05).

CONCLUSIONHuganjiexian decoction can improve rat hepatic fibrosis, possibly via inhibiting the expression of collagen type I, collagen type III, TGFbeta1 and PDGF-BB.

Objective To explore the relationship between self-reported chronic disease and smoking behavior among adult males in Jiangsu Province. Methods In 2007, 2010, and 2013 respectively, a multistage stratified cluster sampling method was used to select residents from 14 adult chronic diseases and their risk factor surveillance sites in Jiangsu Province to investigate the relationship between the prevalence of chronic diseases, smoking and smoking cessation behaviors among men aged 18 to 69 years. Results A total of 8 313 men aged 18 to 69 years had a self-reported prevalence of 1.5%, 1.1%, 1.5%, and 2.8% for cardiovascular and cerebrovascular diseases, malignancies, asthma, and chronic obstructive pulmonary disease (COPD), respectively.The self-reported prevalence of all four chronic diseases was higher in ex-smokers than in current smokers and non-smokers (all P<0.05).Multivariate analysis showed that the quit rate was of those suffering from cardiovascular and cerebrovascular diseases, malignancies, asthma, and COPD, respectively 3.356 times (95% CI: 1.966-5.728), 3.864 times (95% CI: 2.277-6.555), 2.103 times (95% CI: 1.321-3.345), and 2.586 times (95% CI: 1.872-3.573) higher, than those without. Conclusion Smoking cessation rates were significantly higher of those with chronic disease than those without, suggesting that illness would promote smoking cessation behaviors among smokers.

The tracheal aspirates and serum samples of a suspected human case of high-pathogenic avian influenza (firstly found in Shenzhen, China) were collected and tested by a series of assays. The results showed that the RNA extracted from the tracheal aspirate specimens of the patient was confirmed positive for H5N1 avian influenza virus by Real-time PCR. The H5N1 avian influenza virus was isolated from patient's tracheal aspirates on MDCK cell and was named A/Guangdong/2/06(H5N1). The viral load of tracheal aspirates collected at different time points were detected by Real-time PCR. The virus microneutralization and the antigenic ratio of human H5N1 isolated were also assayed. It was found that when the virus load decreased gradually after the disease onset, the serum neutralizing antibody titer in the patient increased to 1 : 160 and subsequently decreased gradually. By molecular analysis, the eight gene segments of A/Guangdong/2/06 revealed to be similar to that of H5N1 avian influenza viruses isolated from south China in 2005-2006. However, there were obvious differences in the gene sequence of the detected H5N1 viral RNA as compared with that of the strains isolated from Vietnam, Thailand and Indonesia.

OBJECTIVEIn mid-July 2005, five patients presented with septic shock to a hospital in Ziyang city in Sichuan, China, to identify the etiology of the unknown reason disease, an epidemiological, clinical, and laboratory study were conducted.

METHODSAn enhanced surveillance program were established in Sichuan, the following activities were introduced: active case finding in Sichuan of (a) laboratory diagnosed Streptococcus suis infection and (b) clinically diagnosed probable cases with exposure history; supplemented by (c) monitoring reports on meningococcal meningitis. Streptococcus suis serotype 2 infection was confirmed by culture and biochemical reactions, followed by sequencing for specific genes for serotype and virulence factors.

RESULTSFrom June 10 to August 21, 2005, 68 laboratory confirmed cases of human Streptococcus suis infections were reported. All were villagers who gave a history of direct exposure to deceased or sick pigs in their backyards where slaughtering was performed. Twenty six (38%) presented with toxic shock syndrome of which 15 (58%) died. Other presentations were septicaemia or meningitis. All isolates were tested positive for genes for tuf, species-specific 16S rRNA, cps2J, mrp, ef and sly. There were 136 clinically diagnosed probable cases with similar exposure history but incomplete laboratory investigations.

CONCLUSIONAn outbreak of human Streptococcus suis serotype 2 infections occurred in villagers after direct exposure to deceased or sick pigs in Sichuan. Prohibition of slaughtering in backyards brought the outbreak to a halt. A virulent strain of the bacteria is speculated to be in circulation, and is responsible for the unusual presentation of toxic shock syndrome with high case fatality.

OBJECTIVETo investigate the effect of premature rupture of the membrane (PROM) on neonatal complications in premature infants.

METHODSThe registration information of 7684 preterm infants with gestational age <37 weeks were collected from the cooperative units in the task group between January 1, 2014 to December 31, 2014. Specially trained personnel from each cooperative units filled in the unified form in a standardized format to record the gender, gestational age, birth weight, PROM, placental abruption, antenatal corticosteroid, Apgar score, amniotic fluid pollution, and complications of the infants. The data were analyzed comparatively between the cases with PROM and those without (control).

RESULTSThe preterm mortality rate was significantly lower but the incidences of ICH, NEC, ROP and BPD were significantly higher in PROM group than in the control group (P<0.05). The 95% confidence interval of the OR value was <1 for mortality, and was >1 for ICH, NEC, ROP and BPD. After adjustment for gestational age, birth weight, gender, mode of delivery, placental abruption, placenta previa, prenatal hormones, gestational diabetes mellitus (GDM), gestational period hypertension and 5-min Apgar score <7, the incidences of NEC, ROP and BPD were significantly different between the two groups (P<0.05) with 95% confidence interval of OR value >1, but the mortality rate and incidence of ICH were not significantly different between the two groups (P>0.05).

CONCLUSIONPROM is a risk factor for NEC, ROP and BPD in preterm infants, and adequate intervention of PROM can reduce the incidences of such complications as NEC, ROP and BPD in the infants.
