OBJECTIVE:
To objectively evaluate the voice rehabilitation status in different period after treatment of Tis--T1 glottic carcinoma by CO2 laser with voice parameters.
METHOD:
A retrospective review of 41 cases with Tis--T1 glottic carcinoma treated by CO2 laser was performed, 23 cases were stage Tis (Tis group) and 18 cases with stage T1N0M0 (T1 group). The range of excision of the lesion by CO2 laser was according to the different stages of the tumor, and ensured theoperation negative margin was by intraoperative frozen pathological examination. We tested and compared the actual voice (coritaine F0, Jitter, Shimmer, NNE and MPT) of 30 cases of healthy middle-aged and old male(normal group) and all the patients at one day prior to operation, three months, six months and one year after operation respectively, which was to evaluate the voice rehabilitation status in different period after operation objectively.
RESULT:
Postoperative pathological examination revealed, 23 cases were squamous epithelium severe atypical hyperplasia, 16 cases were well differentiated squamous cell carcinoma, and 2 cases were moderately differentiated squamous cell carcinoma. Palatoglossal arch mucosal tear occurred in 3 patients. Respiratory difficulties were not seen in all cases, and normal oral feeding was obtained in all cases in postoperative three days. All patients were followed up for one year. There was statistical significance in F0, Jitter, Shimmer of both Tis group and T1 group after operation in different periods(P<0.05). But there was no statistical significance in NNE and MPT between six months and one years after operation in the two groups(P>0.05).
CONCLUSION
CO2 laser surgery is an effective treatment for early glottic carcinoma. Postoperative vocal function was improved in varying degrees, and voice quality gradually improved with the rehabilitation time. Partly objective parameters reflecting the vocal function gradually stabilized after half a year after operation.

OBJECTIVETo compare the ventricular-dynamic parameters and thoracic aorta tension induced by two septic shock models in rats.
METHODSSeptic shock models were induced by cecal ligation or puncture (CLP) and intraperitoneal injection of lipopolysaccharide (LPS) in rats. The carotid artery was cannulated and connected to a pressure transducer to determine mean arterial blood pressure (MABP). Ventricular dynamic parameters, including heart rate (HR), left ventricular developed pressure (LVDP) and maximal rise/fall velocity of ventricular pressure (± dP/dtmax) were determined. Isolated thoracic rings were mounted on an organ bath and the tension of the vessel was recorded.
RESULTThe mortality was 65.2% in CLP shock rats, but no death in LPS shock rats. The MABP and HR of CLP rats were decreased more prominently than those of LPS rats (P < 0.01). Contraction induced by high K(+) (60 mmol/L) or 10⁻⁶ mol/L phenylephrine (PE) in endothelium-intact and endothelium-denuded aortic rings was all attenuated, but in LPS rats it was more prominent (P < 0.01).
CONCLUSIONTwo rat septic shock models can decrease ventricular-dynamic parameters and vasoconstriction responsiveness of aorta. The ventricular-dynamic parameters decrease more prominently in CLP model, while vasoconstriction responsiveness of aorta changes more in LPS model.

OBJECTIVETo investigate whether activation of mitochondrial aldehyde dehydrogenase 2 (ALDH2) and inhibition of mitochondrial permeability transition pore (mitoPTP) were involved in the cardioprotection of ethanol postconditioning in isolated rat heart.
METHODSHearts isolated from male Sprague-Dawley rats were perfused on a langendorff apparatus and subjected to 30 min of regional ischemia (occlusion of left anterior descending artery) followed by 120 min of reperfusion. The ventricular hemodynamic parameters and lactate dehydrogenase (LDH) release during reperfusion were measured. Infarct size was measured by TTC staining method and the expression of ALDH2 at mRNA level of left anterior myocardium was detected by RT-PCR.
RESULTIn contrast to ischemia and reperfusion, ethanol postconditioning improved the recovery of left ventricular developed pressure, maximal rise/fall rate of left ventricular pressure during reperfusion, reduced LDH release and infarct size. The expression of ALDH2 mRNA level was increased. Administration of mitoPTP activator atractyloside attenuated the effect of ethanol postconditioning, LDH release and infarct size were increased, and the recovery of hemodynamic parameters was inhibited. The expression of ALDH2 mRNA was decreased.
CONCLUSIONEthanol postconditioning has cardioprotection effect, which may be associated with upregulating mitochondrial ALDH2 mRNA expression and inhibiting the opening of mitochondrial permeability transition pore.

OBJECTIVETo look into the serological characteristics of a hepatitis E outbreak.
METHODSSera from the first five patients with acute icteric hepatitis who developed the disease successively within ten days and the 1,675 employees routinely having their lunch in a dining hall of a department (outbreak population) were examined for anti.HEV IgM and IgG at 26th days after the outbreak, and the 883 employees of a neighboring department not having their lunch in the hall were selected as control (control population).
RESULTSThe five patients were all positive for anti-HEV IgM and IgG. The positive rates of anti-HEV IgM and IgG in outbreak population were 8.7% and 38.4% respectively, both significantly higher than those in control population which were only 0.1% and 28.6%. The numbers with abnormal ALT in the 145 individuals with anti-HEV IgM(+) of outbreak population were significantly higher than those in the IgM(-) individuals of the same group as well as in control, while the abnormal ALT ratio in the IgM(-) individuals of the outbreak was not higher than that in control. The results from the four patients' serial sera showed that the anti-HEV IgM titers declined gradually and were undetectable at about 4th month after infection, and the IgG titers increased to peak in about 2-3 months after infection, then declined very slowly. The mean IgG titer of the anti-HEV IgM(+) individuals was significantly higher than that of the IgM(-) but IgG(+) individuals in outbreak population, and the latter was significantly higher than the IgG(+) individuals in control, which suggested that the post-infection individuals' immunities to HEV were boosted during the outbreak. There was no difference between sex or age groups for the anti-HEV IgM(+) ratio, but the abnormal ALT was much more frequent in the anti-HEV IgM(+) male than in the female, and no difference was observed between age groups.
CONCLUSIONThe pathogen of the outbreak of acute icteric hepatitis was hepatitis E virus and associated with food intake. Anti-HEV IgM and IgG were used not only for diagnosis of hepatitis E but also for surveilance in mass population. The attack risk was not associated with age or sex, but the abnormal ALT was much more frequent fresh infectors in male.

OBJECTIVETo identify the prevalence and risk factors of diabetes and prediabetes in the community residents above 18 years old in the suburbs of Guangzhou.
METHODSBetween April and May in 2008, the residents above 18 years living in 6 communities of Guangzhou for 5 or more years were sampled with multistage clustering sampling. The sampled residents were surveyed by questionnaires, and physical examination and glucose determination were carried out.
RESULTSA total of 1532 residents were sampled. The incidence of diabetes mellitus in these community residents was 8.46%, and that of impaired glucose regulation was 6.59%. Age, body mass index, family history of diabetes mellitus, case history of hypertension, hyperlipidemia, hypertension and smoking were all the independent risk factors for impaired glucose regulation and diabetes mellitus.
CONCLUSIONDiabetes and prediabetes are prevalent in the community residents in Guangzhou. Controlling the risk factors such as obesity, hypertension, lipid metabolism disorder among the residents above 40 years with a family history of diabetes mellitus and hypertension is key to prevention of impaired glucose regulation and diabetes mellitus.

OBJECTIVESTo investigate the prevalence of oncogenic type of human papillomavirus (HPV) infection and identify the high risk population for conducting immuno/chemoprevention of cervical cancer.
METHODSAll married women aged 30 to 50 with no history of hysterectomy, pelvic radiation and non-pregnant from certain villages of Xiangyuan and Yangcheng County were invited. This study was conducted through two phases. In phase one, subjects sampled the vaginal secretions using the collectors after signing the informed consent. And physicians sampled exfoliated cells from cervix in the phase two. All the specimens were tested with the Hybrid Capture 2 test. The data was managed and analyzed by VFP and SPSS software.
RESULTSThere were 9,683 women participated in this study. Local women welcomed this study and population compliance rate was 75.4%. In tested population, we found 2,666 subjects of HPV DNA positive and HPV prevalence was 27.5%. The rates of different age group were 24.5% (30-34 yrs), 27.4% (35-39 yrs), 28.2% (40-44 yrs), 27.4% (45-50 yrs) respectively and had no significant differences (P = 0.604). The rates were slightly increased with the higher education level and had no differences (P = 0.106). The rate in mountain areas was higher than that in half-mountain areas (P = 0.001).
CONCLUSIONSThe prevalence of HPV infection is indeed high in this region. Local women and health professionals welcome the activities of cervical cancer screening and prevention. It is an emergent task to improve their sanitary condition and prevent them from cervical cancer in these women. A women health cohort is established successfully among high HPV exposed women in rural China. The extensive biologic specimen repository has been successfully established to simultaneously study the etiology, early detection, and immuno/chemoprevention of cervical cancer.

At present, lung cancer ranks second and first respectively in the incidence and the mortality among malignant tumors. It is urgent to find new effective anti-lung cancer drugs with less side effects and relatively defined mechanisms. Endoplasmic reticulum stress (ERS)-mediated apoptosis pathway is an effective way to promote tumor cell apoptosis; diterpenoid tanshinone (DT), an effective part separated from Salviae Miltiorrhizae Radix et Rhizoma, was found to have an anti-lung cancer effect in previous studies via ERS-induced PERK-EIF2α pathway. In this paper, human lung adenocarcinoma PC9 cell line and nude mouse transplantation tumor model were applied to verify the anti-lung cancer effect of DT in vivo and in vitro, and illuminate the potential mechanism via ERS induced IRE1α/caspase 12 apoptosis pathway. The results showed that in vivo, DT could promote PC9 cell apoptosis in a concentration-dependent manner, up-regulate Bip, IRE1 and TRAF2 protein expressions in tumor tissue, reduce tumor weight and alleviate bodyweight loss. In vitro, DT inhibited the proliferation of PC9 cell line in a concentration-dependent manner, and destroyed the structure of mitochondria in PC9 cell, promoted Bax, IRE1α, Bip, TRAF2 and caspase 12 protein expressions, lower Bcl-2 protein expression in a time-dependent manner. DT shows a good effect on anti-lung cancer both in vivo and in vitro. The mechanism is related to the activation of ERS-induced IRE1α/caspase 12 apoptosis pathway and the promotion of cell apoptosis. ERS-mediated apoptosis pathway may be an important target of DT on anti-lung cancer.

Network Meta-analysis was used to evaluate the efficacy and safety of different oral Chinese patent medicines combined with transcatheter arterial chemoembolization(TACE) in the treatment of primary liver cancer. Randomized controlled trials of oral Chinese patent medicines for primary liver cancer were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library and EMbase databases from inception to May 2020. According to the Cochrane recommendation standard, the quality of the included articles was evaluated, and the data were analyzed by RevMan, R software and GeMTC software. A total of 10 kinds of oral Chinese patent medicines and 68 RCTs were included. Network Meta-analysis results showed that: as compared with TACE alone, 10 kinds of oral Chinese patent medicines combined with TACE showed advantages in effective rate, 1-year survival rate, 2-year survival rate, KPS score improvement rate and reduced adverse reaction incidence. In the pairwise comparison of oral Chinese patent medicines, the results showed that Cidan Capsules were superior to Jinlong Capsules and Xihuang Pills in 1-year survival rate. According to the probabi-lity ranking results: Shenyi Capsules and Ganfule were more obvious in improving the effective rate; Cidan Capsules and Shenyi Capsules were more effective in improving the 1-year survival rate; Pingxiao Capsules and Shenyi Capsules had better efficacy in improving 2-year survival rate; Huaier Granules and Shenyi Capsules had better efficacy in improving the quality of life; Huisheng Oral Liquid and Ganfule were more effective in reducing the incidence of adverse reactions(such as nausea, vomiting and leukocytosis). The current evidence showed that oral Chinese patent medicine combined with TACE was superior to TACE alone in efficacy and safety. In terms of the effective rate, 1-year survival rate, 2-year survival rate, KPS score improvement rate and reduced adverse reaction incidence, the optimal treatment measures were Shenyi Capsules, Cidan Capsules, Pingxiao Capsules, Huaier Granules and Huisheng Oral Liquid in turn. However, due to the limitations of the research, the current level of evidence is not high, and clear conclusions and evi-dence strength still need to be further verified and improved by high-quality researches.

To systematically evaluate the efficacy and safety of Huaier Granules in the adjuvant treatment of primary liver cancer. The databases of CNKI, Wanfang, VIP, CBMdisc, PubMed, Cochrane Library and EMbase were searched by computer to screen out the randomized controlled trial on Huaier Granules combined with Western medicine in the treatment of primary liver cancer from the establishment of the databases to January 2020. Data extraction and quality evaluation were conducted for the included literature. Meta-analysis was conducted with RevMan 5.3 software, and evidence quality evaluation was conducted for the outcomes by GRADE profiler software. A total of 24 articles were included, with a total sample size of 2 664 cases. Meta-analysis showed that as compared with Western medicine alone, Huaier Granules combined with Western medicine could improve the objective remission rate(RR=1.38, 95%CI[1.26, 1.51], P<0.000 01), disease control rate(RR=1.29, 95%CI[1.10, 1.52], P=0.002) and 6-month survival rate(RR=1.20, 95%CI[1.10, 1.32], P<0.000 1), 1-year survival rate(RR=1.39, 95%CI[1.23, 1.58], P<0.000 01), 2-year survival rate(RR=1.95, 95%CI[1.28, 2.96], P=0.002), KPS score(MD=17.15, 95%CI[6.47, 27.83], P=0.002) and the improvement rate of KPS score(RR=2.02, 95%CI[1.47, 2.77], P<0.000 1), AFP decline rate(RR=1.40, 95%CI[1.20, 1.62], P<0.000 1), CD3~+(MD=17.34, 95%CI[9.28, 25.40], P<0.000 1), CD4~+(MD=8.62, 95%CI[1.59, 15.64], P=0.02), CD8~+(MD=1.95, 95%CI[-3.93, 7.82], P=0.52), CD4~+/CD8~+(MD=0.42, 95%CI[-0.33, 1.17], P=0.27); reduce the level of AFP(MD=-71.57, 95%CI[-80.42,-62.72], P<0.000 01), recurrence rate(RR=0.76, 95%CI[0.67, 0.85], P<0.000 01), and incidence of adverse reactions(RR=0.60, 95%CI[0.41, 0.89], P=0.01) in patients with primary liver cancer. According to the GRADE system, the evidence for outcome measures was low to very low. The results show that Huaier Granules have certain efficacy and high safety in adjuvant treatment of primary liver cancer, but its effect in reducing adverse reactions and improve immunity remains to be verified. Due to the poor quality of the included studies and evidences, the conclusions still need to be further verified by multi-center, large sample, and randomized double-blind controlled studies.
