Objective To investigate the influence of Tanyu-Tongzhi (TYTZ)recipe on Rho/Rho kinase signal transduction pathway of myocardial ischemia-reperfusion injury in high fat-fed rats.Methods 60 SD rats were divided into 5 groups randomly,a sham-operated group,a model group,a western medicine control group,a high-dose group and a low-dose group of TYTZ recipe.The model of ischemia reperfusion of the myocardium was reproduced by ligation of left descending artery for 30 min followed by releasing the ligation for 2 hours in rats.The downstream substrates of ROCK myosin light chain (MLC) phosphorylation expression of myocardial tissues in rats were detected by Western blotting method.The levels of RhoA,ROCK Ⅱ mRNA were determined with RT-PCR.Results Compared with the model group,the expression of p-MLC and RhoA,ROCK Ⅱ mRNA were lower in low-dose group of TYTZ,there were significant differences between the two groups(P=0.004、0.003、0.018、0.004,P＜0.01).Conclusion The TYTZ Recipe can protect myocardium from MI/RI.The mechanism of action was related to its inhibiting the protein expression of RhoA,ROCK Ⅱ and p-MLC,restraining the activation of Rho/Rho kinase signal transduction pathway.

OBJECTIVETo observe the clinical effects of two different circumcision procedures with the Shang Ring and compare their advantages and disadvantages.

METHODSA total of 527 adult males with phimosis or redundant prepuce underwent Shang Ring circumcision by conventional outward replacement (n = 254) and inward placement (n = 273), respectively. We observed the in-ring nocturnal pain, complications, ring-removal pain, degree of edema, recovery time, and patients' satisfaction after surgery, and compared them between the two groups.

RESULTSCompared with the conventional outward placement (5.9%) of the Shang Ring, the inward placement method showed the advantages of mild in-ring nocturnal pain, a low complication rate, significantly reduced ring-removal pain, and mild edema, but exhibited longer healing time.

CONCLUSIONIn Shang Ring circumcision for phimosis and redundant prepuce in adult males, each of the outward and inward placement methods has advantages and disadvantages of its own, but the latter is more advantageous and feasible.

Objective:To investigate the value of chest CT quantitative index in clinical classification and lung injury severity evaluation of COVID-19.Methods:The current study retrospectively analyzed the clinical and CT data of 438 patients with COVID-19 between January 2020 and March 2020 in Tongji Hospital, Tongji Medical College, Huazhong University of Science & Technology. The clinical types included common type ( n=146), severe type ( n=247) and critical type ( n=45). The chest CT indexes of all patients were quantitatively analyzed by artificial intelligence (AI) deep learning, including whole lung volume, CT lung opacification, ground glass opacification volume (GGO volume; CT value<-300 HU), solid opacification volume (SO volume; CT value ≥-300 HU) and the ratio of volume to the whole lung volume, the ratio of SO volume to GGO volume (SO volume/GGO volume). Kruskal-Wallis test was used to conduct statistical analysis of the differences in quantitative parameters among clinical types, and multiple ordered logistic regression was used to analyze the correlation between quantitative parameters and clinical types. Results:Among the 438 patients diagnosed with COVID-19, severe and critical patients were older ( P<0.05), and most of the critical patients were male ( P<0.05). The main clinical manifestations of all clinical types were fever, followed by cough, fatigue, chest tightness, dyspnea, gastrointestinal symptoms and so on. GGO volume was the main CT manifestation of all the three clinical subtypes. The whole-lung opacification volume, GGO volume, SO volume and their proportions in whole-lung volume significantly increased from common, severe to critical types (all P<0.05). SO volume/GGO volume increased with the severity of clinical type [common type 0.12 (0.03, 0.34), severe type 0.29 (0.11, 0.59), critical type 0.61 (0.39, 0.97)]. Multiple ordered logistic regression analysis showed that whole-lung opacification volume (OR=1.009), SO volume/GGO volume (OR=1.866), GGO volume (OR=1.008) and SO volume (OR=1.016) had a significant positive effect on the severity of clinical typing ( P<0.01). Conclusion:Quantitative indicators of chest CT based on deep learning algorithm (SO volume, GGO volume, SO volume/GGO volume) are closely related to the clinical severity of COVID-19.

Objectives. To investigate the role of endogenous heme oxygenase (HO)/carbon monoxide (CO) system in regulating the process of intussusception (IN) induced by administration of lipopolysaccharide (LPS) in rats.Methods. IN model of rats were induced by lipopolysaccharide. HO activity was determined by the amount of bilirubin formation which was measured with a double-beam spectrophotometer, and HbCO formation was measured by CO-oximeter.Results. The results showed that LPS (10mg/kg) caused IN in up to 40% of the rats at 6h after treatment of LPS. The incidence of IN were significantly increased by 50% (P＜0.05) and by 83.2%(P＜0.01) in HO substrate(heme-L-lysinate)-treated rats and in exogenous CO-treated rats, respectively; but it was significantly decreased by 41.8%(P＜0.05) after administration of ZnDPBG, an inhibitor of heme oxygenase (HO) activity. Furthermore, LPS increased HO activity, HbCO formation cGMP content within colic smooth muscle and the plasma level of cGMP, and these parameters were significantly elevated by 62.6%(P＜0.01), 40.0%(P＜0.01), 49.3%(P＜0.05) and 38.9%(P＜0.05), respectively, compared with LPS-non-IN rats.Conclusion. It is suggested that endogenous HO/CO system plays an important role in the process of IN induced by LPS, and inhibition of HO activity may decrease the formation of IN.

Hypoxia inducible factor 1 (HIF-1) is a heterodimeric transcription factor that plays an important role in oxygen homeostasis. In response to low level of oxygen, subunit HIF-1alpha expression is upregulated and transactivates its target genes essential for energy metabolism, erythropoiesis and vascular development. HIF-1alpha is thought to be able to protect hypoxic cells from apoptosis or necrosis under ischemic and anoxic conditions, the major trauma factors that affect the recovery of brain and spinal cord injury. Here we report the construction of recombinant adenovirus vector overexpressing HIF-1alpha intended for gene therapy against desired neuronal injuries. The recombinant vector could be packaged and yielded significantly high viral titers at 2 x 10(13) CFU in HEK293T cells and good expression levels of HIF-1alpha when superinfected in Hela cells.

OBJECTIVETo assess the economic implications of an annual vaccination strategy against influenza among people who were on a social-health program.

METHODSA retrospective cohort study was conducted. 1900 persons who had received the influenza vaccine were served as vaccine group, while 1049 persons who did not receive the vaccine were served as controls. Cluster random sampling method was used. Both of these two groups came from Donfang Company in which there were 12,109 employers in total and all of them joined the social health insurance program. The survey was carried out when the influenza vaccine was given one year ago.

RESULTSThe rates of vaccine group and control group for respiratory system diseases and cardiovascular diseases who were hospitalized, were 0.51%, 2.47% and 1.64%, 5.62% which showed 68.90% and 56.05% decrease, when compared with the control group. The crude inpatient rate among vaccinees and control group after receiving the vaccination for three and four month were 0.62%, 0.80% and 0.28%, 1.00% respectively. The inpatient rate of oldest-age group decreased by 53.59%, compared with control group. The cost-benefit ratio generated by the use of influenza vaccine in reducing the hospitalization rate was 6.48:1 for Social Health Insurants in Xi'an city.

CONCLUSIONThe Strategy to vaccinate the social-health-insured residents on influenza in Xi'an city had gained better economic benefits in reducing the hospitalization rate of respiratory system diseases and cardiovascular diseases for mild and old-aged persons.
