Objective: To investigate the epidemiological characteristics of pulmonary tuberculosis in Taizhou City from 2016 to 2021, so as to provide the evidence for formulating the pulmonary tuberculosis control measures. Methods: The epidemiological data of pulmonary tuberculosis cases in Taizhou City from 2016 to 2021 were retrieved from the Tuberculosis Management Information System and Infectious Disease Surveillance System of Chinese Disease Prevention and Control Information System, and the trends in the incidence of pulmonary tuberculosis and regional, population and temporal distributions of pulmonary tuberculosis were analyzed using a descriptive epidemiological method in Taizhou City from 2016 to 2021. Results: A total of 15 621 pulmonary tuberculosis cases were reported in Taizhou City from 2016 to 2021, with annual mean reported incidence of 42.12/105. The incidence of reported pulmonary tuberculosis reduced from 43.74/105 in 2016 to 36.31/105 in 2021, with an annual decline rate of 3.65% (χ2trend=34.172, P<0.001). There were 7 606 cases positive for pathogenic tests (48.69%), and the positive rate of pathogenic tests appeared a tendency towards a rise from 2016 to 2021 (χ2trend =470.906, P<0.001). The reported incidence rates of pulmonary tuberculosis were 57.83/105 and 25.46/105 in men and women, and a high incidence rate was reported in patients at ages of 20 to <25 years (72.80/105) and 65 years and older (84.75/105). Farmer was the predominant type of occupation (8 365 cases, 53.55%), and the cases peaked from March to August, with the greatest seasonal index in May (119.76%). A high annual incidence rate of pulmonary tuberculosis was reported in Xianju County (52.51/105) and Wenling City (49.98/105) from 2016 to 2021, and the a high constituent ratio of patients positive for pathogenic tests was seen in Sanmen County (58.71%) and Luqiao District (53.24%). Conclusions The reported incidence of pulmonary tuberculosis showed a tendency towards a decline, and the proportion of pulmonary tuberculosis patients positive for pathogenic tests showed a remarkable increase in Taizhou City from 2016 to 2021. The number of patients peaked in spring and summer. In addition, high incidence of pulmonary tuberculosis was seen in Xianju County and Wenling City.

Objective To analyze the clinical diagnosis and therapeutic effect of primary middle lobe lung cancer,in order to provide evidence for clinical diagnosis and treatment.Methods The clinical data of 45 cases of primary middle lobe lung cancer treated by surgery from January 2002 to January 2007 were ana- lyzed retrospectively.The operation style includes:simple middle lobectomy 12 cases(26.7 %),middle or up- per lobectomy 10 cases(22.2 %),right lung total resection 5 cases(11.1%).Chest exploration was done on 2 cases(4.44 %),palliative resection or vedged resection 2 cases(4.44 %).Results 1 case died from lung in- fection and respiratory failure(2.22 %).15 cases with arrhythmia (33.3 %), 1 case with chylothorax were cured after conservative treatment.The survival rate of 1,3,5 year were 82.1%,64.3 %,32.1% respectively. Conclusion The treatment of primary middle lobe lung cancer is dominated by regular lobectomy. It is difficult to perform middle lobectomy,so double or total lobectomy is done generally.Owing to the more postoperative complications, it should be cautious to perform sleeve resection.It should be avoided to do vedged resection for primary middle lobe lung cancer in order to lessen local recurrence.

Objective:To investigate the relationship between herpesviridae and malignant or benign laryngeal diseases.Method:128 paraffin-embedded laryngeal squamous cell carcinoma and laryngeal epithelium hyperplastic lesions were detected by polymerase chain reaction (PCR) and PCR-ISH for herpesviridae. Result:HSV-1 was detected in 10 cases by PCR,among them 3 were laryngeal squamous cell carcinoma (LSCC),1 was carcinoma in situ(CIS),4 were laryngeal polyps and 2 were laryngeal keratosis. Except 1 LSCC and 1 CIS, 8 of 10 cases were positive while detected by PCR-ISH. In benign diseases, signals were shown from basal layer to superficial cell; in malignant lesions, the signals were scattered in the diseases.Conclusion:Most of laryngeal diseases were not related to herpesviridae, but HSV-1 may acts as initiator in the development of a few cases.

Objective To investigate the expression of pro-inflammatory cytokines in lumbar dorsal root ganglions (DRG) of rats model of high-dose fentanyl induced hyperalgesia. Methods 64 male SD rats were divided into 2 groups (n = 32), fentanyl group and normal saline (NS) group. The rats were injected with fentanyl (60 μg/kg) or NS 4 times in total subcutaneously with a 15-minute interval. Mechanical and thermal nociception were measured via the tail pressure test (tail flick thresholds, TFT) and paw withdrawal test (paw withdrawal latency, PWL) at 1 day before, at 1, 2, 3 and 4 hour and on 1 ~ 7 day after administration. 4 rats were sacrificed and the lumbar DRG were harvested to analyze the expression of PGE2 , IL-1β, IL-6 and TNF-αvia ELISA. Results There were no significant changes of TFT, PWL and the expression of pro-inflammatory cytokines in DRG compared to baseline of rats in NS group. The value of TFT , PWL in fentanyl group were above the baseline at the 1 ~ 4 hour and below the baseline at 1~3 day after fentanyl injections. PGE2 , IL-1β, TNF-α and IL-6 increased on 1,3,5,7 day after fentanyl injections significantly. Conclusions High-dose fentanyl induced significant hyperalgesia and up-regulation of pro-inflammatory cytokines in DRG. The expression pro-inflammatory cytokines peaked later and were more protracted than the change of behavior test and show no direct relationship between the two.

A novel HBV integration site involved in hepatocarcinogenesis was investigated. The HBV DNA integration sites were detected by Alu-PCR in hepatocellular carcinoma tissues, matched surrounding liver tissues in 30 patients with hepatitis B-related hepatocellular carcinoma (HCC) and 3 cases of normal liver tissues. The integration sites and flanking sequences in human genome were sequenced and blasted, and the expression of integrated HBV genes was determined by reverse transcriptase-polymerase chain reaction (RT-PCR). The influence of the up-regulated expression of integrated genes on hepatocarcinogenesis was analyzed. Nineteen integration sites of HBV DNA into HCC tissues were obtained by RT-PCR and sequencing. These genes encoding proteins were: LOC51030, LOC157777, minichromosome maintenance complex component 3 associated protein (MCM3AP), MCTP1, SH3 and multiple ankyrin repeat domains 2 isoform 2, CCDC40, similar to HCG2033532, mitochondrial ribosomal S5 pseudogene 4. One of them was integrated into the intron of MCM3AP. RT-PCR demonstrated that the expression levels of MCM3AP mRNA in HCC tissues, matched surrounding liver tissues and normal liver tissues were in a descendent order. The ratio of MCM3AP mRNA to the GAPDH mRNA in these three tissues was 1.07375, 0.21573, 0.06747 respectively, with the difference being statistically significant among them (P<0.05). Meanwhile, the expression levels of MCM3AP mRNA from HCC tissues in which HBV DNA integrated into MCM3AP were still significantly higher than those without HBV DNA integrated into MCM3AP. It was concluded that the HBV DNA integration sites into human genome were random, and MCM3AP was a new site. The up-regulated MCM3AP mRNA may affect flanking sequences which promote the hepatocarcinogenesis.
