Objective To assess the effect of anti- Helicobacter pylori (Hp) treatment on patients with chronic idiopathic thrombocytopenic purpura (cITP). Methods Fifty-nine patients with cITP and positive-Hp were divided into two groups by random digits table:Hp eradication group (30 cases,given a standard anti-Hp treatment) and placebo controlled group (29 cases,received a placebo). The platelet response of two groups was compared after three months' follow-up. Result The platelet response in Hp eradication group (63.3%, 19/30) was significantly higher than that in placebo controlled group (27.6%,8/29 )(χ2 = 7.59, P ＜ 0.05 ), and the increasing level of platelet count in Hp eradication group [ (33.5 ± 21.6)× 109/L] was higher than that in placebo controlled group [(12.6 ± 19.5) × 109/L] (t = 5.52,P ＜0.05).Conclusion Hp eradication treatment can promote the platelet recovery in mild and moderate cITP patients with positive-Hp.

Objective　To explore the relationship of pathological types of lung cancer with sex, age, site, and clinical diagnosis. Methods　The data of 1 310 patients with lung cancer diagnosed with fibrobronchoscopy, was retrospectively analyzed. Results　①The preliminary clinical diagnosed lung cancers which were comfirmed by fibrobronchoscopic biopsy later were mainly small cell lung cancer. ②The percentage of squamous carcinoma was significantly greater in male (78.0%) than in female (49.7%), but the percentage of adenocarcinoma was significantly higher in female (38.1%) than in male (13.1%)(P<0.0001). ③Among the patients with lung cancer, 53.7% was from 40 to 59 years old and 40.2% over 60. The average age of male patients (56.9 years old) was significantly greater than that of female (51.1 years old) (P<0.0001). ④ The average age of patients with squamous carcinoma and adenocarcinoma was greater in male than in female, but that with small cell carcinoma and squamous carcinoma was greater in female than in male. ⑤The percentage of male with lung cancer in the left lung (37.3%) was greater than that of female (26.0%), but the female had lung cancer in the right lung (59.7%) while male had (49.3%). The left and right upper lobe was more (45.4%) in male, but the right upper and lower lobe was more(43.3%) in female. Conclusion　①The fibrobronchoscopic examination is very important in the diagnosis of lung cancer. ②The pathological types and sites of lung cancer is different in different sex and age, which provide the exact bases for medical and surgical treatment for lung cancer.

AIM: To investigate the clinical features of Axenfeld-Rieger syndrome associated with secondary glaucoma and its surgical treatment.

METHODS: It was a retrospective case series study. The general clinical data and related ocular manifestations in 15 patients(26 eyes)with Axenfeld-Rieger syndrome associated with secondary glaucoma in our hospital from January 2003 to January 2016 were collected and analyzed retrospectively.

RESULTS: Age of the patients ranged from 3-month to 43 years old, and the median age was 11 years old. There were of all 11 patients(73%)had bilateral glaucoma and 4(27%)had unilateral glaucoma. In the aspect of clinical features, hypoplasia or deficiency of the iris was found in 20 eyes(77%), peripheral iridocorneal adhesions was found in 17 eyes(65%)in various extent, and pupil distortion or multiple-pupil was found in 14 eyes(54%); Also posterior embryotoxon was found in 14 eyes(54%)as well; And 11 eyes(42%)had anomalies in corneal size. That root of iris is located at a more anterior position than that of a normal eye was found in all affected eyes by gonioscopy, coupled with different extent of angle synechiae-closure. According to the data, in 15 patients only two had a family history of ARS, while 5 had systematic abnormalities, eyes excepted, in dental, maxillary, cardiovascular, et al. Anti-glaucoma surgeries including trabeculotomy, trabeculectomy, glaucoma valve implantation were performed in 20 eyes. Nine patients(11 eyes)were followed up for 59mo on average. Intraocular pressure was significantly lower than pre-operation(t=2.4185, P=0.0362), and intraocular pressure in 7 followed-up eyes was controlled ≤21mmHg. The long-term success rate of surgery was 64%.

CONCLUSION: The clinical features of Axenfeld-Rieger syndrome associated with secondary glaucoma were diverse. The patients might concomitant with other systematic dysplasia. Although it was tough to treat, surgery for glaucoma could reduce the intraocular pressure effectively.

Objective To evaluate the risk factors associated with in-hospital death in patients co-infected with human immunodeficiency virus and Mycobacterium tuberculosis (HIV-TB). Methods A retrospective case-control study was performed in patients admitted to Shanghai Public Health Clinical Center from November 2004 to May 2009. Fifty-three HIV-TB patients who died during hospitalization were matched with 79 HIV-TB co-infected patients who survived during hospitalization.Clinical, demographic, and radiological characteristics of the two groups were compared by the retrospective case-control study method. Multivariate Logistic stepwise regression analysis was performed to explore the risk factors contributing to death in HIV-TB co-infected patients. Results Among the 459 co-infected patients, 53 (11.5%) cases died during hospitalization and 25 cases died during the first week in hospital. Sixty-four point two percent dead patients (34/53) died from tuberculosis. Several factors were associated with worse prognosis in the death group compared to the survival group, which included body weight≤50 kg (χ2 = 7.50), positive for acid-fast bacilli in sputum smear or culture exam (χ2= 4. 04, 14. 27), drug-resistant/multi-drug resistant Mycobacterium tuberculosis infection (χ2 =9.00,6.39), extra-pulmonary tuberculosis infection (χ2 =6.99), retreated tuberculosis (χ2 = 5. 92), non-standardized anti-tuberculosis treatment (χ2 = 12. 07), extensive pulmonary TB infection (lesions ≥50% of lung fields, χ2 = 20. 21), co-infection with fungi (χ2 =3.46), respiratory failure (χ2 = 4.27), non-pulmonary organ impairment (χ2 = 3.46), HIV infection longer than 5 years (χ2 = 7. 19), non-standardized highly active antiretroviral therary treatment (χ2 =5.16) and CD4+ T lymphocyte count ≤ 200 × 106/L (χ2= 12.99) (all P＜0. 05). Multivariate Logistic regression analysis showed that non-standardized anti-TB treatment, extensive pulmonary TB infection, multi-drug resistant TB infection and CD4+ T lymphocyte count ≤ 200 × 106/L were the major risk factors related to in-hospital mortality. Conclusions Non-standardized anti-TB treatment,extensive pulmonary TB infection, multi-drug resistant TB infection and CD4+ T lymphocyte count ≤200 × 106/L are the major risk factors related to in-hospital mortality in the patients co-infected with TB and HIV.

Objective To evaluate the value of transrectal contrast enhanced ultrasound(TR-CEUS) in diagnosis of benign and malignant prostatic neoplasms.Methods Sixty patients with elevated level of serum prostate specific antigen and suspected prostate diseases were examined with transrectal uhrasound(TRUS), and TR-CEUS.The pattern and intensity of CEUS in these patients were observed;and the patients with nodules were examined with CEUS guided biopsy and sextant system biopsy after ultrasound imaging.Time-intensity curves (TIC) were drawn to calculate the parameters, and the difference between benign and malignant nodes was compared.Results All sixty prostate patients were confirmed by pathological examination.Thirty-seven patients belong to benign lesions, among them 15 patients with nodule lesion had total 20 nodules, while 22 cases had benign prostatic hyperplasia.In 23 cases of malignant lesions, 18 cases had centralized nodules and 5 cases showed diffuse pathologic changes.Benign nodes of inner gland showed a main pattern of homogenous enhancement and a clear node zone, whereas, malignant nodes displayed significant enhancement in peripheral tissue.The time to peak and accelerating time (ACT) of malignant nodes were shorter than those of benign nodes (P <0.05).There was no significance in arrival time (AT) between the two groups (P>0.05).The accordance rate of TR-CEUS in the differential diagnosis of benign and malignant prostatic lesions was higher than that of TRUS (P<0.05).In addition, the sensitivity, specificity and accurate rate of TR-CEUS were higher than those of TRUS, whereas, both misdiagnosis and missed diagnosis rate of TR-CEUS were lower than those of TRUS.Conclusions TR-CEUS has clinical value for early discovery of prostatic cancer and has higher application value to differentiate malignant from benign diseases.

Objective To evaluate diagnostic value of transrectal gray scale contrast enhanced ultrasound (CEUS) in distinguishing benign from malignant nodes of prostate. Methods Thirty-three patients with 38 prostate nodes underwent real-time transrectal gray scale CEUS with SonoVue and contrast pulsed sequence (CPS). Contrast enhancement pattern of the prostate nodes were recorded and time-intensity curves (TIC) were drawn to calculate the parameters and difference between benign and malignant nodes. Results Twenty benign nodes (17 in inner gland) and 18 malignant ones (14 in external gland) were confirmed by pathology. Compared with normal peripheral zone, malignant lesions showed significantly earlier time to enhancement. The time to peak (TTP), accelerating time (ACT) and peak intensity (PI) of malignant lesions were lower than those of benign lesions (P<0.05).There was no significance in arrival time (AT) between the two groups (P>0.05). Conclusion Of all parameters in CEUS, TTP, ACT and PI are different between prostate benign and malignant lesions, and thus contribute to discriminate prostate cancer from benign diseases.

Objective To observe the expression of cytokeratin 14,15 (CK14,CK15) expression level in normal esophageal tissues and esophageal squamous cell carcinoma tissues of different differentiation degree and to analyze the relationship between occurrence,development of esophageal squamous cell carcinoma and CK14,CK15 expression level.Methods Esophageal squamous epithelial tissue from 55 cases of carcinoma tissues and 55 cases of adjacent tissues were collected.Immunohistochemical method was used to compare CK14,CK15 and PCNA expression levels in esophageal squamous carcinoma.Results Expression positive rates of CK14,CK15 and PCNA in esophageal squamous carcinoma were 72.7 ％ (40/55),63.6 ％ (35/55) and 65.5 ％ (36/55),respectively,and PCNA expression was correlated with CK14 or CK15 expression (C =0.585,P ＜ 0.001; C =0.405,P ＜ 0.001).CK14 and CK15 levels were higher in high differentiation carcinoma tissue than those in low differentiation carcinoma tissue,and PCNA expression level was increased in low differentiated carcinoma tissue.CK14,CK15 and PCNA were expressed located in base layer of esophageal squamous epithelial adjacent to carcinoma tissue,and their expression positive rates were 56.4 ％ (31/55),52.7 ％ (29/55) and 56.4 ％ (31/55).CK14 and CK15 levels were higher in esophageal squamous epithelial tissues of far-cut edge than those in tissues of near-cut edge (intraepithelial neoplasia).There were no associations between CK14,CK15 expression and the clinical parameters (P ＞ 0.05).Postoperative survival time in patients with CK14 or CK15 positive expression was shorter than that of patients with negative expression (P ＜ 0.05).Conclusions CK14 or CK15 positive expressions localized to base layer of esophageal squamous epithelial adjacent to carcinoma tissue may play some roles in generation and differentiation of esophageal squamous cell cancer.CK14 or CK15 positive expression in esophageal squamous carcinoma involves in differentiation process.Joint detection of CK14 and CK15 expression has clinical application value for early diagnosis,the degree of differentiation and prognostic judgment in esophageal squamous carcinoma.

Objective To analyze effect of the syphilis prevention and control work among female sex workers(FSWs), and provide reference data for target intervention in Guangdong province.Methods Syphilis prevalence among FSWs from 2009 to 2013 were analyzed statistically based on the data from Guangdong Provincial high-risk groups in sexually transmit-ted infection(STI)control program.Results A total of 34 338 FSWs were detected,including 23 816(69.36%)FSWs at the high-tier venues,8 811(25.66%)middle-tier,and 1 711(4.98%)low tier.The syphilis prevalence of FSWs at high-, middle-,and low-tier venues in 2009 was 2.60%,7.36%,and 10.54% respectively,and in 2013 was 1.45%,2.75%,and 21.88% respectively.Chi-square test showed a downward trend in the prevalence of syphilis among the high and middle tier FSWs in 2009-2013(χ2 =12.807,52.333 respectively,both P <0.001),and remained high among FSWs at low-tier venues(χ2 =0.027,P =0.87).The difference in syphilis prevalence in 2013 among FSWs from different types of venues was statistically significant (χ2 =190.64,P <0.001 ).No significant difference in syphilis prevalence was found among FSWs from Pearl River Delta,eastern,western and northern Guangdong(χ2 =5.24,P =0.07).Conclusion Significant difference is found in prevalence of syphilis among FSWs from different types of settings.FSWs from low-tier settings have a relatively lower syphilis testing rate but with higher infection rate.

Objective To investigate the expression of unfolded protein response (UPR) gene glucose regulated protein 78(GRP78) and X-box binding protein 1(XBP1) in esophageal squamous cell carcinoma, its effect on activation of the endoplasmic reticulum stress (ERS) and its mechanism in the growth of esophageal squamous cell carcinoma. Methods The expressions of GRP78 and XBP1 were detected by immunohistochemistry in 30 samples of esophageal squamous cell carcinoma and 30 samples of normal esophageal squamous epithelium. The correlation between expressions of both proteins and prognosis was analyzed. Results GRP78 positive rate was 83.3 %(25/30) in esophageal carcinoma, while the proportion was 20.0 %(6/30) in normal esophageal (χ2=25.833, P<0.05). XBP1 positive rate was 70.0 % (21/30) in esophageal carcinoma, while the proportion was 26.7%(8/30) in normal esophageal(χ2=20.872, P<0.05). The positive rates of GRP78 and XBP1 in invasive muscular layer of esophageal squamous cell carcinoma were significantly higher than those in invasive mucous layer. Conclusion GRP78 and XBP1 are highly expressed in esophageal squamous cell carcinoma, which may involve the occurrence and development of the esophageal carcinoma.
