Objective:To study the incidence rates of cancer in the urban area of Shijiazhuang city, China in 2012 based on the data of 2,374,827 registered residents. Methods: The incidence of diagnosed cancer cases in 2012 was obtained from the hospital reimbursement database of the medical insurance center of the city by retrieving the records on first-time reimbursement applications for the hospitalization of tumor patients from January 1 to December 31 in 2012. Population census data was obtained from the Population Department of the Shijiazhuang Public Security Bureau. The site-specific and sex-specific age-adjusted incidence rates were calculated. Results:The overall incidence rate, the age-adjusted rate of the Chinese population (ASRC), and the age-adjusted rate of the world population (ASRW) for both men and women were 237.53, 129.86, and 167.71 per 100,000 individuals, respectively. The incidence rate increased with age and peaked in the 75-79 years age groups of men and women at 1,729.42 and 867.35 per 100,000 individuals, respectively. The top ten most frequently diagnosed cancers in males were lung, stomach, colorectal, liver, esophagus, kidney, prostate, leukemia, bladder, as well as lymphoma, whereas those in females were the breast, lung, colorectal, stomach, cervical, uterine body, ovary, lymphoma, esophageal, and liver cancers. The incidence rate and ASRW of all cancers combined in men were 269.05 and 187.52 per 100,000 individuals, whereas those for women were 207.57 and 150.44 per 100 000 individuals, respectively. Compared with the average incidence rates of 31 Chinese cities in 2009, the ASRW of lung, stomach, and colorectal cancers in males from Shijiazhuang was nearly equal to the national level;however, the ASRW of breast cancer in females from Shijiazhuang was higher than the national level. When the incidence rates of Shijiazhuang in 2012 were compared with those of Beijing in 2009, the ASRW of stomach and esophageal cancers in men of Shijiazhuang was twice that of the same cancers in Beijing. However, the same parameters for the pancreatic and prostate cancers in men, as well as the thyroid and uterine body cancers in women of Beijing, were twice the values for Shijiazhuang. Conclusion: The ASRWs of the major types of cancer, such as the lung, stomach, colorectal, and breast cancers, in urban Shijiazhuang in 2012 were identical to those of the 31 Chinese cities in 2009. Compared with Beijing, the incidence rates of pancreatic, prostate, and thyroid cancers were significantly higher in Shijiazhuang, whereas those of esophageal and stomach cancers were significantly lower.

OBJECTIVE：To systematically evaluate the efficacy and safety of linezolid （LZD）combined with routine anti- tuberculosis drugs in the treatment of tuberculous meningitis （TBM），so as to provide evidence-based reference for clinical medi- cation. METHODS ：Retireved from PubMed ，Cochrane Library ，Embase，CNKI and Wanfang database ，randomized controlled trials（RCT）of LZD combined with routine anti-tuberculosis drugs （trial group ）versus routine anti-tuberculosis drugs （control group）were collected from the inception to Jan. 2020. After literature screening and data extraction ， the quality of the included literature were evaluated with bias risk assessment tool recommended by Cochrane system evaluator handbook 5.2. Meta-analysis was conducted by using Rev Man 5.3 software，and sensitivity analysis and publication bias analysis were performed. RESULTS ： Totally 9 RCTs involving 602 patients were included. Meta-analysis showed that total response rate [OR ＝4.05，95％CI（2.26，7.26）， P＜0.000 01]， changes of protein content of cerebrospinal fluid [MD ＝0.48，95％CI（0.20，0.77），P＝0.000 8]，changes of white blood cells count of cerebrospinal fluid [MD ＝44.43，95％CI（20.06，68.81），P＝0.000 4]，changes of cerebrospinal fluid glucose/ synchronous blood glucose [MD ＝0.09，95％CI（0.05，0.14），P＜0.000 1] of trial group were significantly higher than those of control group. There was no statistical significance in the changes of chloride content of cerebrospinal fluid [MD ＝8.08，95％CI（－0.64， 16.80），P＝0.07] and the incidence of ADR [OR ＝1.34，95％CI（0.57，3.11），P＝0.50] between 2 groups. The results of sensitivity analysis showed that there were significant differences comparison with before exclusion when the change of protein content in cerebrospinal fluid and the change of glucose/synchronous blood glucose in cerebrospinal fluid were taken as indexes ，and there was no significant difference comparison with before exclusion when the changes of white blood cell count and chloride content in cerebrospinal fluid were taken as indexes. The results of publication bias analysis showed that there was a certain publication bias in this study. CONCLUSIONS ：LZD combined with conventional anti-tuber culosis drugs is effective and safe for TBM. Because the inconsistent results of sensitivity analysis and publication bias exists in publication bias analysis ，the conclusions need to be further confirmed by more large sample and multi-center studies.
