Abstract: Objective To analyze the treatment outcomes of elderly patients with pulmonary tuberculosis in Chongqing, so as to provide reference for the prevention and control strategies of the epidemic of elderly pulmonary tuberculosis. Methods The data of tuberculosis cases aged ≥65 years in Chongqing from 2015 to 2020 were collected from the National Health Insurance Information Project Disease Prevention and Control Information system. Descriptive statistical methods were used to analyze the data. Results The registration rates of elderly active pulmonary tuberculosis patients and etiological positive patients were 110.95/10-5and 32.25/10-5 in 2015 and 84.06/10-5 and 57.29/10-5 in 2020. The annual decline rate of active tuberculosis registration was 5.40%, and the annual increase rate of pathogenic-positive tuberculosis registration was 12.18%. The registration rates of active tuberculosis patients and etiological positive patients in the whole population were 70.75/10-5 and 17.63/10-5 in 2015 and 50.34/10-5 and 29.14/10-5 in 2020. The annual decline rate of active tuberculosis registration was 6.58%, and the annual increase rate of pathogenic-positive tuberculosis registration was 10.57%. From 2015 to 2020, a total of 25 931 cases of elderly pulmonary tuberculosis were registered, of which 21 374 (82.43%) cases were successfully treated and 4 010 (15.80%) cases had unfavorable outcomes. The proportion of cured and death patients showed an increasing trend year by year (χ2trend=313.853, 100.502, P<0.01). From 2015 to 2020, the average annual successful treatment rate of elderly pulmonary tuberculosis in the whole city was 82.43%, with the lowest rate in southeast Chongqing (74.23%), followed by urban areas (81.99%). The success rate of elderly pulmonary tuberculosis treatment in the whole city, west Chongqing, northeast Chongqing and southeast Chongqing showed a downward trend year by year (χ2trend=230.199, 35.278, 108.076, 112.130, all P<0.01), with annual decline rates of 2.77%, 2.26%, 3.0% and 4.12%, respectively. Among the registered elderly patients, female, 65-<75 years old, Han nationality, newly diagnosed, no complications, and negative for etiology (χ2=15.234, 255.910, 146.842, 179.998, 25.575, 131.170, P<0.01) had higher success treatment rates. Conclusions The prevalence of pulmonary tuberculosis in the elderly population in Chongqing City is declining, but the positive registration rate of etiology is increasing annually, and the success rate of treatment is decreasing. Therefore, it is necessary to strengthen the systematic management, publicity and education of elderly patients (especially those in southeast Chongqing, male, positive patients and severe patients) to effectively control the epidemic of tuberculosis in the elderly.

Objective To explore the pattern of lymph node metastasis in patitsen with squamous cell carcinoma of the thoracic esophagus and its significance in lymphadenectomy.Methods The clinical data of 230 patients who received radical esophagectomy with three-field lymphadenectomy was analyzed.The metastatic sites of lymph nodes were correlated with tumor location by chi-square test.Logistic regression was used to analyze the relationship between clinic pathoingical factors and lymph node metastasis.Results Lymph node metastases were found in 133 of the 230 patients(57.8%).The average number of resected lymph nodes was 25.3? 11.4 per patient(range 11~71).The rates of lymph node metastasis were 41.6%,19.44%and 8.3%in the neck,thoracic medi- astinum and abdominal cavity for patients with upper thoracic esophageal carcinoma,33.3%,34.7%and 14%for patients with mid- die thoracic esophageal carcinoma and 36.4 %,34.1%and 43.2 %for patients with lower thoracic esophageal carcinoma.No signifi- cant difference in cervical or thoracic metastatic rate was observed among upper,middle and lower thoracic carcinoma.The difference in lymph node metastatic rate for nodes in the abdominal cavity was significant among upper,middle and lower thoracic carcinoma. The lower thoracic esophageal cancers were more likely to metastasize to the abdominal cavity.Logistic-regression showed depth of tu- mor invasion and angiolymphatic invasion were factors influencing lymph node metastasis.Conclusion Cervical and mediastinal node dissection should be performed independently from tumor location.Abdominal node dissection should be conducted more vigorously for lower thoracic esophageal cancer than of other locations.Patients with greater tumor grade,depth of tumor invasion and angiolymphatic invasion were more prone to develop lymph node metastasis.

RNA has received more attention in the field of forensic medicine and the development of the new biological markers based on RNA shows great significance in the analysis of complex cases. circular RNA (circRNA) is a kind of non-coding RNA which is widely reported recently. Although the regulatory mechanisms of generation and expression are not fully clear, the existing research indicates that circRNA has important biological functions. CircRNA has a cell-type-specific expression with great stability and a high expression level, which makes it meaningful in forensic applications potentially. In this paper, the research progress, the generation and regulation of circRNA as well as its biological characteristics and functions are summarized, which will provide references for related studies and forensic applications.

OBJECTIVETo explore the effect of Bushen Gujin Recipe (BGR) on serum and synovial expression of interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-α) in knee osteoarthritis (KOA) model rabbits.
METHODSTotally 36 8-month-old healthy male New Zealand white rabbits were randomly divided into 4 groups, i.e., the normal control group, the model group, the Western medicine group (Meloxicam, at the daily dose of 6 mg/kg), and the TCM group (BGR, at the daily dose of 53 g/kg), 9 in each group. Modeling was performed in all rabbits except those in the normal control group by using Hulth A method. All medication was performed for 8 consecutive weeks. Contents of IL-1 and TNF-α were detected using ELISA from serum, partial synovial tissue of the front knee joint, cartilage and subchondral bone of the medial femoral condyle.
RESULTSThe joint space became narrowed in the Western medicine group, ranging between the model group and the TCM group. The articular surface was rough with obvious osteophytes. The joint space was slightly narrower in the TCM group; the articular surface was slightly rough with mild osteophytes. Compared with the normal control group, contents of IL-1 and TNF-α in serum and synovial increased in the model group (P < 0.01). Compared with the model group, contents of IL-1 and TNF-α in serum and the synovial fluid decreased in the two treatment groups (P < 0.01). There was no statistical difference in contents of IL-1 and TNF-α between the Western medicine group and the TCM group.
CONCLUSIONBGR promoted the synthesis of cartilage matrix and carti- lage repair through inhibiting the secretion of IL-1 and TNF-α, and prolonging cartilage degeneration.

Objective: To investigate the mechanisms of electroacupuncture (EA) at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) in intervening diabetic gastroparesis (DGP) based on calcium-activated chloride channel. Methods: Forty Sprague-Dawley rats were randomly divided into four groups, including a normal control group (group A), a model group (group B), an EA group (group C) and a metoclopramide group (group D), with 10 rats in each group. A single intraperitoneal injection of 2% streptozotocin (STZ) combined with 8-week high-glucose high-fat diet was used to establish a DGP rat model. After intervention, gastrointestinal propulsive rate was observed; the expression level of transmembrane protein 16A (TMEM16A) was examined by immunohistochemistry; the Ca2+ concentration in interstitial cells of Cajal (ICCs) was detected by immunofluorescence; and whole-cell patch-clamp technique was applied to detect the current intensity of calcium-activated chloride channel (ICaCC) in ICCs in gastric antrum. Results: After modeling, the blood glucose levels in group B, group C and group D were significantly increased compared with group A (all P<0.01); after intervention, compared with group B, the blood glucose levels in group C and group D were significantly decreased (P<0.05, P<0.01); the intra-group comparison of blood glucose level between after modeling and after intervention found significant difference only in group C (P<0.01). The gastrointestinal propulsive rates in group B, group C and group D were significantly different from that in group A (P<0.01 or P<0.05); the gastrointestinal propulsive rates were markedly higher in group C and group D than in group B (P<0.01, P<0.01). The expressions of TMEM16A in group B and group C were decreased compared with group A (P<0.01, P<0.05); the expressions of TMEM16A in group C and group D were increased compared with group B (P<0.01, P<0.05). The fluorescence intensity of Ca2+ was significantly lower in group B than in group A (P<0.01); the fluorescence intensity of Ca2+ was significantly higher in group C and group D than in group B (P<0.01, P<0.05). ICaCC in ICCs in group B was significantly decreased compared with group A; ICaCC in group C and group D were increased compared with group B. Conclusion: EA at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) can significantly improve gastrointestinal motility in DGP rats by up-regulating the ICaCC in ICCs.

OBJECTIVETo explore the relationship between ulcerative colitis (UC) and lung injuries by assessing their clinical manifestations and characteristics.
METHODSFrom July 2009 to April 2012, 91 UC patients presenting to Longhua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study. According to the scores of disease activity index, the patients were divided into the mild, moderate, and severe groups. Meanwhile, the records of pulmonary symptoms, chest X-ray image, and pulmonary function were reviewed.
RESULTSSixty-eight (74.7%) patients had at least 1 pulmonary symptom, such as cough (38.5%), shortness of breath (27.5%), and expectoration (17.6%). And 77 (84.6%) had at least 1 ventilation abnormality. Vital capacity value was significantly lower in the severe group than that in the mild group (91.82%±10.38% vs. 98.92%±12.12%, P<0.05).
CONCLUSIONSLung injury is a common extraintestinal complication of UC. According to the theory in Traditional Chinese Medicine that the lung and large intestine are related, both the lungs and large intestine should be treated simultaneously.

OBJECTIVETo observe the clinical efficacy of Shugan Yiyang Capsules in the treatment of asthenospermia and its action mechanisms.
METHODSWe randomly assigned 135 asthenospermia patients to groups A (n = 47), B (n = 45), and C (n = 43) to be treated with Shugan Yiyang Capsules, oral levocarnitine, or combination of the two. We observed sperm quality and the level of α-glucosidase in the seminal plasma before and after medication.
RESULTSThe total effectiveness rate was 70.21% in group A (markedly effective in 16 cases and effective in 17), 68.89% in group B (markedly effective in 15 cases and effective in 16), and 83.72% in group C (markedly effective in 16 cases and effective in 20), significantly higher in C than in A and B (P < 0.05). Both sperm quality and the level of α-glucosidase in the seminal plasma were improved in the three groups of patients, most obviously in group C.
CONCLUSIONShugan Yiyang Capsules can be used for the treatment of asthenospermia, and its effect can be enhanced in combination with oral levocarnitine.
