Objective To investigate the distribution of traditional Chinese medicine (TCM) syndrome types of functional dyspepsia (FD) in Guangzhou, and to explore their correlation with some factors such as residence time in Guangzhou, gender, age, and Helicobacter pylori (Hp) infection. Methods A total of 326 cases of FD patients from Guangzhou were investigated. Database of the related clinical data was built and analyzed. Results The commonly-seen TCM syndrome types of FD patients in Guangzhou were spleen-deficiency and qi stagnation, disharmony of liver and stomach, dampness-heat of spleen and stomach, deficiency-cold in spleen and stomach, and concurrence of cold and heat, accounting for 41.71%, 26.07%, 11.96%, 11.04% and 9.20%, respectively. There were significant differences among the TCM syndromes(P < 0.05). The differences of average age of onset, residence time in Guangzhou, FD subtypes and Hp infection were significant among each syndrome type (P < 0.05). Conclusion The distribution of TCM syndrome types of FD in Guangzhou is dominated by spleen-deficiency and qi stagnation, and the syndrome types are correlated with residence time in Guangzhou, gender, average age of onset, FD subtypes, and Hp infection.

OBJECTIVEThis longitudinal study aimed to investigate the caries status of primary and permanent teeth among 6-year-old children in Sichuan Province from 2010 to 2012.

METHODSA sample that comprised 652 6-year-old children from six different elementary schools (three represented the urban areas, and the other three represented the rural areas) were examined according to a baseline, with follow-up examinations at 1, 2, and 3 years. Eruption and caries experience were re- corded using World Health Organization criteria.

RESULTSThe prevalence rates of primary tooth caries of 6-year-old children in Sichuan Province for 3 years were 74.23% (484/652), 75.61% (493/652), and 81.90% (534/652). The filling rate of the primary teeth was 5.87% (145/2,471) in 2012, with significant differences (P < 0.01) between the urban areas [10.84% (133/ 1,227)] and rural areas [0.96% (12/1,244)]. The total pit and fissure rate of the first molar was 14.11% (92/652) in 2012, with significant differences between the two areas (P < 0.01) [rural: 0.66% (2/303); urban: 25.79% (90/349)].

CONCLUSIONThe pre- valence of caries in the primary and permanent teeth of 6-year-old children was high. An increasing prevalence tendency was observed as the age increased. The prevalence of first molar caries indicated that prevention and control of dental caries should be performed as early as possible.

AIM: To investigate the effect of nitric oxid e (NO) and taurin on hemorrhagic shock /reperfusion injury. METHODS: Twenty-four rabbit s were divided randomly into 3 groups ( n= 8): control group and shock group and taurine group. The model of hemorrhagic shock/reperfusion was used. The activities of ni tric oxide synthase (NOS),superoxide dismutase(SOD),lactate dehydrogenase (LDH)and the contents of malondialdehyde(MDA),nitric oxide pvoducts( NO - 2/NO - 3) in plasma were observed before shock and shock 1.5 h,reper fusion 1 h ,2 h and reperfusion 3 h. RESULTS: ①During shock/reperfusion, the ac tivities of NOS,LDH and the contents of MDA,NO - 2/NO - 3 were significan tly highe r, but the activity of SOD was significantly lower in plasma of shock group than that of before shock and shock 1.5 h. ②At 3 h reperfusion, the activity of NOS and the contents of MDA, NO - 2/NO - 3 were significantly higher,bu t the act ivity of SOD was significantly lower in the lung and heart of shock group than t hat of control group. ③ Taurine(40 mg?kg -1 ,iv) attenuated all the c hanges above mentioned at total time points of reperfusion. ④ A close correlation was shown between MDA content and NO - 2/NO - 3 content in plasma, lung and i n heart. CONCLUSION: These results suggeste that NO may be involved in oxida nt-mediated shock/reperfusion, antagonistic effect of taurine on hemorrhagic shock/reperfusi on injury may be relate d to decreasing the generation of NO and anti-lipoperoxidation.

Objective To observe the clinical efficacy of Qingjinchangfei drink for treating AECOPD.Methods We Used random number table to separate 84 patients in to two groups:treatment group and control group.The treatment group used western medicine conventional treatment and Chinese medicine decoction Qingjinchangfei drink.The control group used western medicine conventional treatment.Both two groups were 14 days treatment.We recorded the improvement of symptoms and signs everyday.We compared the lung function,inflammatory cytokines,such as IL-8、IL-2 before and after treatment in the two groups.Results The total efficient in treatment group was obviously better than that in control group.The indicators such as clinical symptoms,signs,pulmonary function indicators were obviously better than that in control group.Compared with before treatment,IL-8,ET,MDA and TNF-? in sputum and blood were obviously lower but IL-2 was obviously higher.Conclusion Qingjinchangfei drink plus western medicine conventional treatment for treating AECOPD was obviously better than western medicine conventional treatment.

Hemolysins of Leptospira interragans have been shown to be the virulence factor in the pathogenesis of leptospirosis and 10 potential hemolysin genes were charecterized by genomic annotation of L.interrogans serovar.Lai strain 56601. In the present study, the LA0202 gene supposed to encode one of the new potential hemolysin was cloned and the protein encoded was purified. The purified protein was shown to have highly hemolytic activity as demonstrated on the sheep blood agar plate. It was also confirmed that the LA0202 protein-mediated hemolysis on sheep erythrocytes was osmotically protected by PEG6000. Meanwhile, this protein could induce pore formation on sheep erythrocytes and cause damages on the membrane of human L-02 liver cells. In addition, it could induce apoptosis of human L-02 liver cells after treatment of cells with this protein for 24 hours. It is evident that LA0202 protein acting as a pore-formong hemolysin can induce cytotoxic damage on mammalian cells.

Objective To study the efficacy of emergency orthotopic liver transplantation(EOLT) for acute(hepatic) failure(ALT).Methods A retrospective review was undertaken on the clinical data of 8 patients undergoing emergency liver transplantation for ALT.Results The 8 patients completely regained consciousness in 12 to 72 hours after operation.No case developed central nervous complications.One case of severe(hepatitis) complicated by acute renal failure died of respiratory infection and ARDS on postoperative day 7.One case who refused to take medication died from chronic rejection 12 months after operation.One case was(complicated) by bile duct stricture and biliary sludge at 14 months postoperatively and survived for 18 months.Four of the other 5 cases were followed up for 17 months and 1 cases for 14 months,and thir quality of life was excellent.3 of them have returned to work.Conclusions Emergency orthotopic liver thansplantation is an effective means to treat ALF.Intensive care and effective treatment preoperatively are pre-requisite(conditions) to ensure the success of EOLT.

Objective To evaluate the dose distribution in clinical target volume (CTV) and organs-at-risk (OARs) in three dimension therapy plans in patients with squamous cell carcinoma of tongue receiving postoperative intensity-modulated radiotherapy (IMRT) or conventional radiotherapy (CRT) by dosimetric study. Methods Thirty-five patients with squamous cell carcinoma of tongue were divided into CRT group(n=17) and IMRT group(n=18). All patients underwent head-and-neck immobilization with a thermoplastic mask and planning CT scan, and target volume and OARs were contoured. Dose calculation and plan optimization were performed. All three dimension plans passed quality assurance before treatment. The dosimetry of therapy plans with IMRT or CRT in target volume and OARs dose distribution was compared by dose-volume histogram (DVH), conformity index (CI) and homogeneous index (HI). Results There were significant differences in D95 (isodose line to cover 95 percent target volume), CI, HI, minimum dose and maximum dose in CTV of therapy plans between patients with IMRT and CRT(P < 0.01), and there was no significant difference in mean dose of CTV(P > 0.05). The radiation dose on salivary glands (both parotid glands and contralateral submandibular gland) in patients with IMRT was significantly lower than that in patients with CRT(P < 0.01). Conclusion Compared with dose distribution of CRT plans, there are more advantages in improving dose distribution at the target volume and sparing salivary glands in IMRT therapy plans in patients with squamous cell carcinoma of tongue.

Background Hainan Island is a tropical and subtropical area in China,with a suitable climate for fungal growth and breeding.Keratomycosis occurred frequently in this area.It is essential to analyze the causative genus and investigate the sensitive drugs prior to the clinical treatment of fungal keratitis.Objective This study attempted to analyze the fungal population of fungal corneal ulcer patients in Hainan Island of China and examine the susceptibility of antifungal drugs.Methods A series cases observational study was carried out.One hundred and seventy-four eyes of 174 fungal corneal ulcer patients were enrolled in Hainan Eye Hospital from February 2014 to May 2016 based on the diagnosis criteria in Ophthalmology.The specimens at corneal lesions were collected under the aseptic conditions,and fungus was examined by KOH based smear.Mycological culture was performed with potatodextrose agar and Sabourand's agar.The 82 cultured causative strains were identified to characterize the spectrum of the species associated with keratitis infections in Hainan Province.Susceptibilities of these causative strains to ten antifungals were determined in vitro by slip diffusion method.Results By smear microscopy,fungal hyphae and spores were found in 34 specimens of 126 patients,with the positive rate 27.0％.In 174 specimens of fungal culture,82 strains of fungi were found,with the positive rate 47.1％,and typing results revealed that the isolates were distributed among species in the fusarium (47.5％),non-spore fungus (12.2％),aspergillus (9.8％) and phoma (9.8％).Nystatin was proved to be the most effective drug to 77 strains of antifungal drug susceptibility,followed by amphotericin B and terbinafine,with the susceptibility of 88.3 ％,72.7 ％,and 71.4％,respectively.Conclusions Fusarium species,non-spore fungus,aspergillus,and phoma are common pathogenic fungi of keratomycosis around Hainan Island in China,and nystatin,amphotericin B and terbinafine are efficient in the treatment of the fungal corneal ulcer.
