Objective: To observe the clinical efficacy of heat-sensitive moxibustion plus Western medicine in treating patients with diabetic peripheral neuropathy (DPN). Methods: A total of 70 patients with DPN were divided into an observation group and a control group by sealed envelope method combined with the random number table method, with 35 cases in each group. The control group was treated with routine medicine, and the observation group was treated with heat-sensitive moxibustion on the basis of the treatment in the control group. After 2 courses of treatment, the scores of Toronto clinical scoring system (TCSS) and vibration perception threshold (VPT) in both groups were observed, and the clinical efficacy was compared. Results: During treatment, 3 cases dropped out in the control group and 4 cases in the observation group. After treatment, the total effective rate in the observation group was higher than that in the control group (P<0.05). The scores of TCSS and VPT in both groups decreased after treatment, and the intra-group comparison showed statistical significance (both P<0.05). The scores of TCSS and VPT in the observation group were lower than those in the control group, and the differences were statistically significant (both P<0.05). Conclusion: Heat-sensitive moxibustion plus Western medicine can improve the symptoms in patients with DPN, and has a better curative effect than the Western medicine alone.

OBJECTIVE: To eludicate the risk factors of mechanical ventilation and prolonged mechanical ventilation in patients with severe multiple injuries. METHODS: Consecutive patients with severe multiple injures who were treated in Peking University People's Hospital Trauma Medical Center between December 2016 and December 2019 were enrolled in this restropective chart-review study. According to mechanical ventilation and ventilatory time, the patients were divided into mechanical ventilation (MV) group and non-mechanical ventilation (NMV) groups, prolonged mechanical ventilation (PMV) group and shortened mechanical ventilation (SMV) groups. Clinical data such as gender, age, base excess, mechanism of injury, Glasgow Coma Scale (GCS), abbreviated injury scale (AIS) and injury severity score (ISS) were collected. To indentify the risk factors of mechanical ventilation and prolonged mecha-nical ventilation, univariate and multivariate Logistic analyses were carried out. RESULTS: In the present study, 112 patients (82 male, 30 female) with severe multiple injuries having a median age of 52 (range: 16-89 years) and a median ISS of 34 (range: 16-66) were enrolled. The primary mechanism of injury was traffic accident injury and falling injury. In the study, 62 and 50 patients were assigned to MV and NMV groups, respectively. Logistic analysis showed that GCS (OR=0.72, 95%CI: 0.53-0.92, P=0.03), base excess (OR=0.56, 95%CI: 0.37-0.88, P=0.002) and multiple rib fracture (OR=1.72, 95%CI: 1.60-2.80, P=0.012) were independent significant risk factors for mechanical ventilation after severe multiple injuries. Within the mechanical ventilation group, 38 and 24 patients were assigned to PMV and SMVgroups, respectively. Compared with the SMV group, the PMV group had a higher ISS and higher rate of severe head trauma. The length of hospital stay of PMV group was longer than that of SMV groups. Meanwhile, the incidence of tracheotomy in PMV group was high. CONCLUSIONS GCS, base excess and rib fracture might be independent risk factors for mechanical ventilation. Higher ISS and lower GCS might prolong the ventilatory time and the length of hospital stay. Meanwhile, the incidence of tracheotomy was high in PMV group because of the longer ventilatory time and poor consciousness.

OBJECTIVETo observe the effect of calorie restriction on the high fat diet rats mRNA expressions of liver forkhead box O1(FoxO1), phosphoenolpyruvate carboxykinase (PEPCK), glucose-6-phosphatase (G-6-P) and to explore the possible mechanisms.

METHODS24 normal 6-week-old male Wistar rats were randomly divided into three groups: normal chow group (NC, n = 7), high fat diet group (HF, n = 9) and calorie restriction group (CR, n = 8). They were fed for 12 weeks. At the end of the experiment, the rats were sacrificed and their fasting blood glucose (FBG), insulin (INS), triglycerides (TG), total cholesterol (TC) were measured. Their visceral fat (VF) and body weight (BW) were also measured and VF/BW was calculated. Gene expression was investigated by using semi-quantitative RT-PCR methods. Liver histology was studied with HE stained slides.

RESULTSCompared with the NC group, HF group rats developed visceral obesity which was accompanied by higher FBG, plasma INS, TG, and TC. The levels of FoxO1, PEPCK, and G-6-P increased by 18.9%, 33.8%, and 24.6%, respectively (P less than 0.01). Liver steatosis was observed with microscopy. The BW, VF FBG, INS, TG and TC of the CR group rats were lower in comparison to those of the HF group. The levels of FoxO1, PEPCK and G-6-P were lower by 26.6%, 35.0%, 34.3% (P less than 0.01). Meanwhile, liver steatosis was also milder.

CONCLUSIONCalorie restriction can inhibit the expressions of FoxO1, PEPCK and G-6-P, strengthen insulin signal conduction, suppress gluconeogenesis and thus regulate glycometabolism.

A quantitative real-time PCR assay was developed to measure the proviral load of human T-lymphotropic virus type I (HTLV-I) in peripheral blood. The technology utilizes special primers and Taqman MGB fluorescence probe to measure amplification products from the gag-pro-pol polyprotein gene of HTLV-I. HTLV-I copy number was normalized to the amount of cellular DNA by quantitation of the beta-actin gene, The amplification system was sensitive to detect 5 copy/microL. The standard curve had a good linearity when the quantity for the gene was between 10(3) and 10(7) copy/microL (R2 = 0.999). Good reproducibility was observed in each intra- and inter-assay. We also measured proviral load in peripheral blood in 12 HTLV-I seropositive former blood donors. Proviral load for HTLV-I infected donors ranged from 0.015 to 12.819 copy/cell in WBC with the mean of 3.116 copy/cell.

Objective To evaluate the changes in epithelial thickness profile and its relationship with diopter following small incision lenticule extraction (SMILE) for moderate and high myopia.Methods Together 46 myopia or myopic astigmatism (92 eyes) who underwent SMILE were included under the informed consent from January 2016 to March 2017 and were decided into 2 groups according to the diopter:moderate myopia group (58 eyes)and high myopia group (34 eyes).Epithelial thickness profile was measured using spectral-domain optical coherence tomography at different corneal zones (0-2 mm,＞ 2-5 mm and ＞ 5-6 mm cornea) preoperatively before surgery and 1 month and 6 months after surgery for observing the changes in epithelial thickness and its correction with diopter.Results The mean epithelial thickness in the central zone was (55.68 ± 3.61) μm before surgery,and,6 months after surgery,it was thickened by (3.85-±3.99),(3.46 ±3.29) and (2.85 ±3.18) μm in the 0-2 mm,＞2-5 mum and ＞5-6 mm cornea respectively,and the difference was statistically significant among the three zones (P ＜ 0.01).After surgery for 6 months,the epithelial thickness in the high myopia group was thickened more obviously compared with the moderate myopia group (t =1.440,P =-0.047).And no correlation was found between changes in the epithelial thickness at 0-2 mm cornea and diopter after surgery(moderate myopia group:r =0.219,P=0.633;high myopia group:r =0.197,P =0.585).Conclusion Significant epithelial thickening was observed after SMILE,presenting the thickened epithelium.The higher the diopter was,the more thickened the epithelium was.The epithelial changes does not appear to affect the diopter after SMILE.

Objective Comparing the difference of virulence between the strain CGRn5310 (HTNV) and the strain HR54 (SEOV) isolated both from Rnttus norvegicus. Methods Suckling mice were used to compare the difference of virulence between the two strains. Hantavirus antigens were detected in brain and lung tissues collected from the infected mice. Results Compared with the control group, all infected mice grew slowly. Furthermore, the mice inoculated intracerebrally with either CGRn5310 or HR45 appeared ruffled fur, and reduced activity, followed by neurological symptoms, such as paralyses and convulsions. The half lethal dose (LD_(50)) of CGRn5310 strain was 10~-6.42, whereas the LD_(50) of HR54 strain was 10~-4.51. Hantavirus antigens were identified in brain and lung tissues from the mice infected with the strain CGRn5310 and the strain HR54. Conclusion LD_(50) of the strain CGRn5310 was significantly higher than that of the strain HR54. Our results suggested that the virulence of the spillover hantavirus might only slightly be influenced by the non-reservoir rodents.

Antibiotic-associated diarrhea(AAD)in children is a type of diarrhea that occurs after the use of antibiotics in children,and its pathogenesis is closely related to the intestinal flora.The medication of antibiotics can affect the metabolic function of the intestinal flora and the immune function of the body,and then leads to the occurrence of AAD.In the view of Chinese medicine,AAD in children is mainly involved the spleen,and the etiology of the disease is due to the weakness of the spleen and stomach of the body constitution together with the attack of the pestilential pathogen and the accumulation of drug toxin.The pathogenesis of ADD in children is characterized by spleen deficiency with predominant dampness,deficiency of spleen qi,and insufficiency of spleen yang.Spleen deficiency is the root cause of pediatric AAD,and spleen and intestinal flora have commonality,so the treatment of pediatric AAD can be performed from the perspective of the spleen.The treatment of pediatric ADD from the spleen follows the principle of strengthening and activating the spleen,and the regulation of the spleen for achieving the purpose of treating the disease from the root can be achieved by the methods of strengthening spleen and draining dampness,strengthening spleen and replenishing qi,and strengthening spleen and warming yang separately with the fundamental prescriptions of Shenlin Baizhu Powder,Sijunzi Decoction,and Fuzi Lizhong Pills.

The aim of this study was to detect the rate of T-helper (Th)17 cells and interleukin (IL)-17 level in peripheral blood of patients with primary immune thrombocytopenia (ITP) and to explore their clinical significance. The proportion of Th17 cells from 48 patients with ITP and 28 healthy controls was detected by flow cytometry, and the IL-17 level was evaluated by enzyme-linked immunosorbent assay (ELISA). The results showed that the percentage of Th17 cells in ITP group was (1.40 ± 1.35)%, which was significantly higher than that in healthy control group (P < 0.05), but in the glucocorticoid hormone-treated group it was significantly lower than that in treated group without glucocorticoid hormone(P < 0.05). The level of IL-17 expressed by Th17 cells in ITP patients was (19.624 ± 5.187) pg/ml, which was higher than that in the healthy control group (P < 0.05), it was lower in the glucocorticoid hormone treated group than that in treated group without glucocorticoid hormone, but there was no statistically significant difference between the glucocorticoid treated and treated group without glucocorticoid hormone (P > 0.05). It is concluded that the Th17 cells may involve in the pathogenesis of ITP, and the glucocorticoid hormone probably plays a therapeutic role through inhibiting Th17 cells.
