AIM: To evaluate the diagnostic accuracy of macular ganglion cell - inner plexiform layer ( GCIPL ) measurements using high- definition optical coherence tomography ( Cirrus HD - OCT ) ganglion cell analysis algorithm for detecting early and moderate to severe glaucoma.
METHODS:Twenty normal control persons, 26 patients with early glaucoma and 29 patients with moderate to severe glaucoma were enrolled in this study. Macular GCIPL, optic nerve head ( ONH ) parameters and peripapillary retinal nerve fiber layer ( RNFL ) thickness were measured in each subject. Then all measured results of each parameter were calculated using SPSS17. 0. Areas under the receiver operating characteristic curves ( AUC) of each parameter were calculated to compare the diagnostic accuracy for detecting early and moderate to severe glaucoma.
RESULTS: For detecting early glaucoma, AUC of average RNFL and seven clock value of RNFL were the biggest ( 0. 871 and 0. 896 respectively ), the AUC of parameters in GCIPL were also significant, among them,
the average GCIPL showed bigger AUC(0. 847) than the minimum GCIPL (0. 812). For diagnosing moderate to severe glaucoma, the AUC of rim area was 0. 992, which was bigger than that of average RNFL ( 0. 991 ). The minimum GCIPL showed bigger AUC ( 0. 983 ) than the average GCIPL (0. 967). For early glaucoma diagnosis, the sensitivity of average RNFL was the highest (76. 9%), while the average GCIPL has the highest specificity (93. 5%).
CONCLUSION: AS a new diagnostic parameter for detecting glaucoma, GCIPL shows similar diagnostic potential compared with RNFL. For early glaucoma diagnosis, average RNFL is the most important parameter, while screening early glaucoma, average GCIPL should be paid more attention.

Objective: To observe the difference in clinical efficacy between acupuncture with point selection based on syndrome differentiation along the meridians and acupuncture at non-meridian and non-acupoint points for functional dyspepsia (FD). Methods: A total of 74 FD patients were randomized into an observation group and a control group, with 37 cases in each group. Both groups received acupuncture treatment. Zusanli (ST 36) and Neiguan (PC 6) were selected in the observation group, with Taichong (LR 3) and Neiting (ST 44) added for excess syndrome, and Gongsun (SP 4) and Yinlingquan (SP 9) added for deficiency syndrome. Four non-meridian and non-acupoint points were selected in the control group. The treatments in both groups were performed once a day with a 2-day break after 5 consecutive treatments, which constituted one treatment course. A total of 4 courses were performed. The scores of Nepean dyspepsia index (NDI) and Leeds dyspepsia questionnaire (LDQ) were recorded before and after treatment, and during follow-up (8, 12, 16, 20 and 24 weeks after recruitment) to assess the clinical efficacy. Results: The NDI scores in the two groups after treatment and at each time point during follow-up were higher than those before treatment (all P<0.05), and the LDQ scores were lower than those before treatment (all P<0.05). The NDI scores after treatment and at each time point during follow-up in the observation group were higher than those in the control group (all P<0.01); the total LDQ score and scores of upper abdominal pain, postprandial satiety and upper abdominal burning sensation after treatment and at each time point during follow-up in the observation group were significantly lower than those in the control group (P<0.01 or P<0.05).. Conclusion: Acupuncture with point selection based on syndrome differentiation along the meridians has a better curative effect than acupuncture at non meridian and non-acupoint points in the treatment of FD.

OBJECTIVETo investigate the effect of Shengmai Injection (SMI) on blood coagulation in patients with chronic heart failure (CHF).
METHODSSixty patients with CHF were randomly divided into two groups, the 30 patients in the treated group were treated with SMI plus conventional treatment of western medicine, and the 30 in the control group treated with conventional treatment alone. The changes of cardiac function were observed and levels of plasma P-selectin, von Willebrand's factor (vWF) and D-dimer were determined.
RESULTSThe total effective rate and the markedly effective rate in the treated group were higher than those in the control group respectively. The levels of P-selectin, vWF and D-dimer lowered in both groups significantly after treatment, but the effect of lowering was better in the treated group than that in the control group.
CONCLUSIONHypercoagulative state exist in patients with chronic heart failure. SMI could improve the state in patients, which may reduce the occurrence and developing of emboic events to certain extent.

Background:
Vocal cord polyps are commonly encountered in the otorhinolaryngology department. The risk of anesthesia is high in patients with large vocal cord polyps. Awake intubation with appropriate airway tools provides a favorable safety profile.Case: We present the case of a 60-year-old male patient who had been suffering from a large vocal cord polyp for 16 years. Electronic laryngoscopy revealed that the vocal cord polyp was approximately 1.5 cm in diameter. The polyp had a pedicle and demonstrated synchronous motion with respiratory excursion. It covered almost the entire glottic area during inspiration and moved away from the glottis during expiration. A Disposcope endoscope was used for awake tracheal intubation, and the surgery was completed successfully.
Conclusions
The Disposcope endoscope can be a useful option for awake orotracheal intubation in cases of anticipated difficult intubation and difficult facemask ventilation.

OBJECTIVETo determine the effects of Varglaucocalyx on c-fos gene expression during global myocardial ischemia-reperfusion.
METHODForty Wistar rats were divided into 5 groups: group N as control; group CN as ischemia-reperfusion control and group XH, XM and XL treated with Varglaucocalyx 5%, 1%, 0.5% respectively prior to ischemia-reperfusion. The isolated rat hearts were perfused in condition of constant temperature and pressure, and then the left ventricular myocardiums were extracted for use. The expression of c-fos protein was detected by immunochemical method. The expression of c-fos protein were quantified by using computer image analysis system.
RESULTCompared with the values of group N, protein expressions relative area of c-fos gene (PERA) were increased significantly in group CN, XH, XM, XL(P < 0.01), but decreased significantly in group XH, XM, XL, compared with those of group CN (P < 0.05). The PERA of c-fos gene in group XM, XL were significantly lower than in group XH (P < 0.01), and the PERA of c-fos gene in group XM were lower than in group XL(P < 0.05).
CONCLUSIONVarglaucocalyx can effectively depress the expression of c-fos gene in myocardium which may account for its protection against myocardial ischemia-reperfusion injury, and the middle and the low concentrations of Varglaucocalyx are more effective than the high concentrations.

Objective To investigate the prevalence change of drinking water type of endemic fluorosis and the effect of control measures implemented in Huangyuan county of Qinghai province. Methods In 2009, all the endemic fluorosis villages in Huangyuan county were divided into two degrees, light and medium, according to the water fluorosis content before implementing the improving water project, 1 to 2 villages were selected from each degree village, respectively,as monitoring sites, and a total of 3 villages were selected. Source water and tap water samples were collected from each village and water fluoride concentration was determined. Dental fluorosis of all children aged 8 to 12 of monitoring villages was examined, and urine samples were collected by age group of children for determination of urinary fluoride. Clinical skeletal fluorosis of adults over 16 years of age was examined, and 20 copies of adults urine samples were collected to determine urinary fluoride. One village was selected in the 3 villages monitored to conduct X-rays examination of skeletal fluorosis. Water fluoride was tested in accordance with the "Non-metallic Targets Test Methods for Drinking Water" (GB/T 5750.6-2006); urinary fluoride was tested by fluoride ion-selective electrode method (WS/T 89-1996); dental fluorosis was diagnosed using Dean method;adult skeletal fluorosis was diagnosed by "Clinical Diagnostic Criteria for Endemic Skeletal Fluorosis"(WS 192-2008). Results Twelve water samples were assayed, water fluoride was (0.35 ± 0.43) mg/L. The detectable rate of dental fluorosis of 122 children aged 8-12 was 34.43%(42/122) and the geometric mean urinary fluoride was 0.89 mg/L of the 96 children. Of the 834 adults aged 16 and over, clinical detection of skeletal fluorosis was 47.72% (398/836) and geometric mean urinary fluoride was 1.10 mg/L of the 65 cases of adult urine samples assayed, detection rate of X-rays was 31.4% (11/35) in Gangou village of the 35 adults examined.Conclusions In Huangyuan county, water fluoride of the 3 surveyed villages are normal but the endemic fluorosis is still serious. It should strengthen monitoring and analyze the causes and improve prevention measures.

ObjectiveTo investigate the development trend of drinking water type of endemic fluorosis in Qinghai province, and to provide the basis for the prevention and treatment of the disease. MethodsIn 2009, six monitoring counties were chosen by using simple random sampling methods, all diseased villages of the six monitoring counties were classified into light, moderate and severe disease types according to water fluorine content on the historical data, and 1 village was respectively chosen from each type. In monitoring villages with improved water, 3 tap water and one source water samples were collected, respectively. Five water samples were collected randomly in water unimproved monitoring villages according to water well locations of east, west, south, north and center. The fluorine content in water and urine was determined according to the Standard Testing Methods for Drinking Water (GB/T 5750-2006). Children aged 8 to 12 were examined for dental fluorosis by Dean method.Clinical osteofluorosis of all the resident over the age of 16 was examined, 2 village of these counties were randomly selected, and clinically diagnosed patients with skeletal fluorosis were examined again by X-ray using Diagnostic Criteria of Endemic Skeletal Fluorosis (WS 192-2008). Urine sample of 30 children aged 8 to 12 and of 20 adults over the age of 16 were randomly collected and urinary fluoride was determined by F-ion selective electrode method (WS/T 89-2006). ResultsImproving water projects had been implemented in 14 monitoring villages of the 18 villages in 6 counties, the rate of improved-water was 77.78%(14/18). Among the 14 projects, 5 improved-water projects ran normally, and 9 projects ran with intermittently water supply. Seventy-five water samples were tested, themean of water fluoride was 0.48 mg/L. The prevalence of dental fluorosis was 31.95% (285/892), that of clinical skeletal fluorosis was 36.55%(1570/4295) and the X-ray detection rate of skeletal fluorosis was 25.64% (20/78).Five hundred and seventy-one urine samples of children were determined, and geometric mean of urinary fluorine was 1.04 mg/L; 370 adult urine samples were determined, and geometric mean of urinary fluorine was 1.52 mg/L Conclusion Epidemic of drinking water type of endemic fluorosis is still serious in Qinghai province, and drinking water defluoride measures should be further strengthened and improved.

Gastrointestinal stromal tumor (GIST) represents the most common intramural mesenchymal tumor of the gastrointestinal tract, but the synchronous occurrence of GIST in the stomach and gynecological cancer is rare. We present a unique case of a 56-year-old female patient who was diagnosed with the synchronous development of GIST and an isolated parenchymal splenic metastasis of ovarian cancer. She underwent a wide local excision of gastric lesions with splenectomy. A morphological (histological and immunohistochemical) study established a spindle-cell type of gastrointestinal tumor that expressed CD117, and a parenchymal recurrence of ovarian papillary serous adenocarcinoma. The patient has remained alive and disease-free for 30 months since the last operation. A small GIST concomitant with an isolated parenchymal splenic metastasis of ovarian cancer is rarely encountered. The coexistence of GIST with other malignancies constitutes an intriguing oncologic model. Surgeons are advised to be alert against possible primary GIST accompanying other neoplasms.
