The pituitary-thyroid axis in dogs of hemorrhagic shock was studied by determination of serum T_4, T_3, rT_3 and TSH. Comparing with pre-shock condition, in shock dogs without dopamine (DA) treatment, serum T, and T_3 were decreased, rT_3 incre ascc and TSH unchanged. But in shock dogs treated by DA, serum T_4 and T_3 were much lower than those in shock dogs without DA and serum TSH was significantly lower (P

0.05), but their SR was much lower(P

Objective To seek the ancients’ method for acupuncture treatment of epigastric pain and explore the ancients’ regularities in point selection for acupuncture treatment of this disease to provide a reference and basis for guidance of modern clinical treatment. Method Search words related to epigastric pain were established. A database was set up. Frequency analysis and data mining technique-associated rules were used to investigate the use frequencies of different acupoints and meridians, and regularities in acupoint combination in ancient acupuncture treatment of epigastric pain. Result In ancient acupuncture treatment of epigastric pain, the points more frequently used and more accepted were Zhongwan (CV12), Zusanli (ST36), Neiguan (PC6), Shangwan (CV13), Geshu (BL17), Gongsun (SP4) and Jianli (CV11). Meridian points were the main ones. The points of meridians going through the epigastrium were often selected. Acupoint combination was mainly based on syndrome differentiation-based point selection plus symptomatic point selection.

BACKGROUND:Ankylosing spondylitis is an autoimmune disease at high inflammatory state, and its pathogenesis is stil unclear. Besides, there is a lack of entirely satisfactory curative strategies. OBJECTIVE: To explore the immunoregulation capability of bone marrow mesenchymal stem cels from ankylosing spondylitis patients on macrophages and the potential therapeutic use of bone marrow mesenchymal stem cels from healthy donors on ankylosing spondylitis. METHODS: Bone marrow mesenchymal stem cels were extracted from 21 healthy donors and 25 ankylosing spondylitis patients respectively, and passage 4 cels were used in subsequent experiments. A human monocytic cel line was induced to differentiate into macrophages. The phenotypic markers of bone marrow mesenchymal stem cels and macrophages were detected by flow cytometry. Expressions of tumor necrosis factor-α and tumor necrosis factor-α-stimulated gene 6 (TSG-6) proteins in the supernatant of co-culture system were detected by ELISA. Quantitative real-time PCR was applied to detect the mRNA level of cytokines secreted by bone marrow mesenchymal stem cels and macrophages. RESULTS AND CONCLUSION:The typical mesenchymal stem cel surface markers were expressed in both bone marrow mesenchymal stem cels from healthy donors and patients with ankylosing spondylitis, and CD68 was detected positively in induced macrophages. The protein and mRNA levels of tumor necrosis factor-α secreted by macrophages co-cultured with bone marrow mesenchymal stem cels from patients with ankylosing spondylitis were obviously higher than those from healthy donors (P < 0.05). TSG-6 secreted by bone marrow mesenchymal stem cels from patients with ankylosing spondylitis was lower than that by bone marrow mesenchymal stem cels from healthy donors in both RNA transcriptional and protein levels (P < 0.05). Our study demonstrates that bone marrow mesenchymal stem cels from patients with ankylosing spondylitis shows abnormal immunoregulatory function on inhibiting the tumor necrosis factor-α secretion from macrophages, which reveals a mechanism of immune disorder in ankylosing spondylitis. The therapeutic mechanism of bone marrow mesenchymal stem cels from healthy donors may work by secreting enough TSG-6 to inhibit the activation of macrophages in patients with ankylosing spondylitis, and thereby to decrease the secretion of tumor necrosis factor-α.

Objective:To investigate the effect of everting resection natural orifice specimen extraction surgery (NOSES) on postoperative function in patients with colorectal cancer.Methods:The clinical data of 78 patients with colorectal cancer treated in Chongqing Bishan District People's Hospital from June 2019 to June 2020 were retrospectively analyzed. According to the selected surgical methods, they were divided into the study group (45 cases) and the control group (33 cases). The control group underwent traditional laparoscopic radical resection of colorectal cancer, and the study group underwent everting resection NOSES. Perioperative indicators such as intraoperative bleeding, operation time, postoperative exhaust time and hospitalization time were observed in the two groups. Anal function indicators [anal constriction pressure, fecal incontinence severity score (Wexner score)], coagulation function indicators [activated partial thromboplastin time (APTT), prothrombin time (PT)], the levels of inflammatory factors [interleukin-6 (IL-6), C-reactive protein (CRP)] and pain factors [nerve growth factor (NGF), prostaglandin E2 (PGE2), neuropeptide Y (NPY)] before and after operation were compared between the two groups.Results:There were no significant differences in intraoperative bleeding and operation time between the two groups ( t values were 1.30 and 0.56, both P > 0.05); the postoperative exhaust time and hospitalization time of the study group were shorter than those of the control group ( t values were 26.88 and 7.42, both P < 0.05). At 3 months after operation, the anal constriction pressure in the two groups was lower than that before operation [study group: (177±10) mmHg (1 mmHg = 0.133 kPa) vs. (184±10) mmHg, t = 3.22, P < 0.001; control group: (178±10) mmHg vs. (184±10) mmHg, t = 2.36, P = 0.020]; the Wexner score was higher than that before operation [study group: (9.0±1.2) points vs. (7.9±1.2) points, t = 4.26, P < 0.001; control group: (10.3±1.2) points vs. (7.9±1.2) points, t = 7.80, P < 0.001], and the Wexner score in the study group was lower than that in the control group ( t = 4.57, P < 0.001). At 1 day after operation, APTT and PT in the two groups were shorter than those before operation (all P < 0.05), and APTT and PT in the study group were shorter than those in the control group [APTT: (26.2±2.2) s vs. (28.3±2.2) s, t = 4.23, P < 0.001; PT: (9.34±0.17) s vs.(11.03±0.41) s, t = 24.93, P < 0.001]. At 1 day after operation, the levels of IL-6 and CRP in the two groups were higher than those before operation (all P < 0.05); the levels of IL-6 and CRP in the study group were lower than those in the control group [IL-6: (8.6± 2.2) ng/L vs. (17.2±3.1) ng/L, t = 14.26, P < 0.001; CRP: (2.16±0.22) mg/L vs. (2.99±0.24) mg/L, t = 15.84, P < 0.001]. At 1 day after operation, the levels of NGF, PGE2 and NPY in the two groups were higher than those before operation (all P < 0.05), and the levels of NGF, PGE2 and NPY in the study group were lower than those in the control group [NGF: (302±7) pg/ml vs. (319±8) pg/ml, t = 9.76, P < 0.001; PGE2: (189±4) ng/L vs. (196±5) ng/L, t = 6.56, P < 0.001; NPY: (164±10) ng/L vs. (177±11) ng/L, t = 5.36, P < 0.001]. Conclusions:Everting resection NOSES can effectively shorten the postoperative exhaust time and hospitalization time of patients with colorectal cancer, have less impact on coagulation function and anal function, reduce the inflammatory reaction and the level of pain factors.

Objective:To compare the efficacy and prognosis between fluorescent laparoscopic and conventional laparoscopic radical resection of colorectal cancer.Methods:A total of 114 colorectal cancer patients in Bishan District People's Hospital of Chongqing from June 2019 to January 2021 were selected as the research objects, and they were divided into two groups according to the diagnosis and treatment time. Forty-four patients receiving treatment from June 2019 to February 2020 were enrolled as group A, and 70 patients receiving treatment from March 2020 to January 2021 were set as group B. Patients in group A received fluorescent laparoscopic radical resection of colorectal cancer, and patients in group B received conventional laparoscopic radical resection of colorectal cancer. The operation time, intraoperative blood loss, metastatic lymph node clearance rate, clinical efficacy (the overall response rate was calculated as complete remission + partial remission), postoperative complication rate and recurrence rate within 1 year were compared between the two groups.Results:The clearance rate of metastatic lymph nodes was 86.95% (40/46) in group A, which was higher than 72.22% (52/72) in group B, and the difference was statistically significant ( χ2 = 3.55, P = 0.049). There were no statistical differences in operation time and intraoperative blood loss between the two groups (all P > 0.05). The overall response rate was 86.36% (38/44) in group A, which was higher than 74.28% (52/70) in group B, and the difference was statistically significant ( χ2 = 5.03, P = 0.024). The incidence of complications in group A was 9.09% (4/44), which was not significantly different from that in group B (11.42%,8/70) ( χ2 = 0.16, P = 0.692). The recurrence rate within 1 year of group A was 11.36% (5/44), which was lower than that of group B (24.42%, 15/70), but the difference was not statistically significant ( χ2 = 1.89, P = 0.169). Conclusions:Compared with conventional laparoscopy, fluorescent laparoscopic radical resection of colorectal cancer has better clinical efficacy, higher clearance rate of metastatic lymph nodes, and does not increase the incidence of postoperative metastasis and complications.

Cranial magnetic resonance imaging (MRI) examinations were performed in 419 patients with type 2 diabetes mellitus (T2DM) from June to December 2016.The brain white matter lesions were defined by white matter hyperintensity (WMH) in MRI,which was detected in 380 cases (WMH group) and not detected in 39 cases (non-WMH group).The Montreal Cognitive Assessment (MoCA) was used to evaluate the cognitive function.The study showed that there were significant differences in the duration of diabetes,the proportion of hypertension,total cholesterol (TC) and MoCA scores between the two groups (all P＜0.05).The age,duration of diabetes,hypertension and glyclated hemoglobin (HbA1c) were significantly correlated with white matter lesions(OR=1.157,1.116,5.184,1.128;P＜0.05);and the white matter lesions,age,and body mass index (BMI) were significantly correlated with cognitive dysfunction in diabetic patients (OR=2.137,1.175,1.247;P＜0.05).The study result indicates that control of white matter lesions may prevent and improve cognitive dysfunction in T2DM patients.

Objective To evaluate the efficacy and safety of ilaprazole sodium for injection in the treatment of peptic ulcer bleeding.Methods It was designed as a multi-center,stratified randomized,double-blind,positive drug parallel controlled and non-inferiority study.From October 2014 to April 2015,at 40 hospitals,patients with peptic ulcer hemorrhage confirmed by gastroendoscopy were enrolled and divided into the ilaprazde sodium group (10 mg ilaprazole sodium for injection every 24 h,the first dose doubled) and the positive control group (40 mg of omeprazole sodium for injection every 12 h).The course of both treatment was 72 h.The hemostasis rate of overall group at 72 h,the clinical rebleeding rate at four to seven days,the blood transfusion rate,the incidence of switching to other treatments and the incidence of adverse reactions were compared between the two groups.A chi-square test or Fisher's exact probability method were performed for statistical analysis.Results A total of 533 patients with peptic ulcer bleeding were enrolled,355 patients in the ilaprazole sodium group and 178 patients in the positive control group.The hemostasis rates of ilaprazole sodium group and positive control group at 72 h were 97.69 ％ (339/347) and 97.14 ％ (170/175),respectively,and the difference was not statistically significant (P＞0.05).There were no rebleeding patients in both groups at four to seven days.The blood transfusion rates of ilaprazole sodium group and positive control group were 5.07 ％ (18/355) and 3.37 ％ (6/178).The incidence of switching to other treatments was 0.56％ (2/355) and 0.56％ (1/178),respectively,and the differences were not statistically significant (both P＞ 0.05).The incidence of adverse reactions in the ilaprazole sodium group was 3.94％ (14/355),which was lower than that of positive control group (8.43％,15/178).And the difference was statistically significant (Fisher's exact probability method,P=0.042).Conclusions The efficacy of ilaprazole sodium for injection in the treatment of peptic ulcer bleeding is similar to that of omeprazole sodium for injection.Moreover,the smaller the dose,the lower the frequency of administration and the better the safety.
