Objective To evaluate the efficacy of potassium sodium dehydroandroan drographolide succinate (PSDS) combined with routine therapy for rotavirus enteritis in children.MethodsA total of 148 children with rotavirus enteritis were included and divided into an observation group and a control group by random number table method, 74 in each group. The children in the observation group were treated with intravenous PSDS combined with routine therapy, and those in the control group with intravenous ribavirin combined with routine therapy. Serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were determined by enzyme-linked immunosorbent assay, and plasma lactate dehydrogenase (LDH), creatine kinase (CK), and creatine kinase-MB (CK-MB) were determined using standard clinical laboratory procedures. The clinical efficacy was evaluated. Results The total efficacy rate in the observation group was significantly higher than that in the control group (91.9%vs. 78.4%;χ2=2.314,P<0.05). After the treatment, the serum levels of IL-6 (18.24 ± 3.62 ng/mlvs. 25.36 ± 5.25 ng/ml; t=2.425,P<0.05) and TNF-α (20.86 ± 4.28 ng/mlvs. 31.22 ± 7.15 ng/ml;t=2.503,P<0.05), and the plasma levels of LDH (104.25 ± 22.06 U/Lvs. 150.26 ± 37.22 U/L;t=2.316,P<0.05), CK (84.25 ± 13.57 U/Lvs. 107.88 ± 16.28 U/L;t=2.327,P<0.05) and CK-MB (22.30 ± 4.24 U/Lvs. 32.26 ± 7.14 U/L;t=2.426,P<0.05) in the observation group was significantly lower than those in the control group. The time to diarrhea resolution (2.42 ± 0.53 dvs.3.56 ± 0.78 d;t=2.316,P<0.05) and the time to fever resolution(2.11 ± 0.32 dvs.2.63 ± 0.43 d;t=2.472,P<0.05) in the observation group were significantly delayed than those in the control group, and the hospital length of stay longer (6.23 ± 1.42 dvs. 4.35 ± 0.96 d;t=2.413,P<0.05).Conclusions PSDS combined with routine therapy may reduce inflammatory response, protect from myocardial injury, and promote recovery in children with RVE.

Objective: To learn the interaction of serum direct bilirubin and blood lipids on the risk of carotid atherosclerosis and carotid plaque. Methods : The subjects were selected from Hangzhou Wuyunshan Sanatorium from March 2016 to December 2018. Demographic information,laboratory testing results and carotid intima-media thickness（IMT）were collected. The logistic regression model was employed for the association of direct bilirubin,blood lipids and their interaction with the risk of carotid atherosclerosis and carotid plaque. Results: Totally 8 308 subjects were recruited. Among them,616（7.41%） subjects had carotid atherosclerosis,and 2 409（29.00%）subjects had plaques. The results of multivariate and multinomial logistic regression analysis showed that high level of direct bilirubin was associated with decreased risks of carotid atherosclerosis（OR=0.701,95%CI：0.537-0.916）and carotid plaque（OR=0.647,95%CI：0.527-0.795）;high TC level（OR=1.335,95% CI：1.106-1.611）, high LDL-C level（OR=1.338,95%CI：1.098-1.629）and low HDL-C level（OR=1.431,95%CI：1.148-1.783）were associated with increased risks of carotid atherosclerosis;high TC level（OR=1.325,95% CI：1.151-1.525）and high LDL-C（OR=1.311,95%CI：1.130-1.520）were associated with increased risks of carotid plaque. There were interactions between direct bilirubin and TC or LDL-C on the risk of carotid plaque（P<0.05）. Compared with the subjects with high level of direct bilirubin and normal level of TC,the subjects with normal level of direct bilirubin and high level of TC had significantly higher risk of carotid plaque（OR=1.831,95%CI：1.438-2.333）;compared with the subjects with high level of direct bilirubin and normal level of LDL-C,the subjects with normal level of direct bilirubin and high level of LDL-C had significantly higher risk of carotid plaque（OR=1.814,95%CI：1.427-2.306）. Conclusion The interactions between direct bilirubin and TC or LDL-C increase the risk of carotid plaque. It is important to strengthen blood lipid control in the patients with normal level of direct bilirubin and hyperlipidemia.

Objective To assess the therapeutic value of transcatheter arterial chemoembolization combined 125iodine seed implantation for primary hepatic carcinoma with portal vein tumor thrombus.Methods The data of 23 patients ranging from 34 to 70 years old [ average age ( 56 ± 8) years ] with primary hepatic carcinoma with portal vein tumor thromhosis of type Ⅱ and type Ⅲ were retrospectively collected.The tumor number of liver parenchyma ranged from 1to 15 ( median number 4).The average diameter of tumor thrombus was (20.5 ± 1.5 ) mm and average length was ( 37.4 ± 2.6 ) mm.All of the tumors of liver parenchyma in 23 patients were treated by transcatheter arterial chemoembolization (TACE) and tumor thrombus were treated with 125iodine seed implantation.Before the 125iodine seed implantation,the formula dosage,the number,the spatial distribution,the intensity of radioactivity and the matched peripheral dosage of seed were calculated by treatment planning system (TPS).Then the 125iodine seeds were implanted in different levels and locations of port vein thrombosis under CT guided.Results The follow-up period ranged from 1to 26 months.The times of transcatheter arterial chemoembolization were 1to six times (median time 3.1±0.4) and the 125iodine seed implantation in the port vein thrombosis were 1to 2 times ( median time 1.4 ± 0.5 ).The numbers of implanted 125iodine seeds were 4 to 17 ( median number 7.0 ± 1.0).The median survival time was 18.0 months (3-24 months).The 3,6 and 12 months survival rates were 91.3％ ( 21/23 ),69.6％ ( 16/23 ),and 60.9％ ( 14/23 ).There was no severe side-effect related to therapy.Conclusions Transcatheter arterial chemoembolization combined 125iodine seed implantation for portal vein tumor thrombosis could significantly prolong the median survival time of patient with primary hepatic carcinoma with portal vein tumor thrombosis.

BACKGROUND:The low oxygen environment after femoral fracture and cerebral trauma wil induce series of related cytokines expression, including hypoxia-inducible factor 1αand core binding factorα1, which play key roles in regulating bone healing. However, whether the accelerated bone healing is correlated with the expression of hypoxia-inducible factor 1αand core binding factorα1 is stil unknown.
OBJECTIVE:To construct rat models of brain injury, to compare the expression level of hypoxia-inducible factor 1αand core binding factorα1 in femoral fracture combined with cerebral trauma rats and simple femoral fracture rats, and to assess the influence of cerebral trauma on bone healing.
METHODS:Rats were randomly divided into blank group, simple femoral fracture group and femoral fracture combined with cerebral trauma group. At 1, 2, 3 and 5 weeks after modeling, rats were executed. Bone healing was evaluated using femoral fracture end X-ray score and hematoxylin and eosin staining at cal us tissues. Besides, the expression levels of hypoxia-inducible factor 1αand core binding factorα1 of three groups were determined with immunohistochemistry.
RESULTS AND CONCLUSION:Bone healing in the femoral fracture combined with cerebral trauma group was better than that of simple femoral fracture group. There was significant difference in the expression level of hypoxia-inducible factor 1αand core binding factorα1 between the simple femoral fracture group and femoral fracture combined with cerebral trauma group (P<0.05). At the same time, the level of simple femoral fracture group and femoral fracture combined with cerebral trauma group was significantly higher than that of blank group, and that in femoral fracture combined with cerebral trauma group was significantly higher than that of simple femoral fracture group (P<0.05). Results verified that the expression levels of hypoxia-inducible factor 1αand core binding factorα1 of rats with femoral fracture combined with cerebral trauma were significantly high, which may be the major reason why the bone healing was accelerated after fracture combined with brain injury.

Conclusion Intravas-cular ultrasound in patients with intervention can improve postoperative acute benefit.

Objective To report our first clinical experience with a novel modified culotte technique for the treatment of true coronary bifurcation lesions. Methods The novel modified culotte technique (the mono-ring culotte) stenting was done in which the side branch (SB) stent was deployed firstly followed by ex vivo wiring of a most proximal cell of SB stent with the hard end of main branch (MB) wire. Secondly, the MB stent was deployed through the most proximal cell of SB stent. The procedure was ended with kissing balloon dilation. From June 2014 to March 2015, 15 patients with true coronary bifurcation lesion were treated with mono-ring culotte stenting in our center. Results The procedures were successful in all cases without procedural complication and in-hospital major adverse cardiovascular events. The procedural time was (34. 3 ± 9. 6) min, fluoroscopic time was (18. 1 ± 3. 8) min, and contrast volume was (112. 0 ± 24. 5) ml, respectively. Post-procedurally, the residual stenosis of the main and the side branch were (10. 0 ± 2. 5)% and (10. 2 ± 5. 3)% , respectively. Conclusions The mono-ring culotte stenting is safe and feasible for treatment of true coronary bifurcation lesions, and may be superior to the conventional culotte stenting.

Objective To explore the prevalence and clinical characteristics of food allergy in bronchial asth-matic children less than 14 years old in China. Methods A case - controlled study was designed. The questionnaires were given to children,who were diagnosed to be asthmatic during the national epidemiological survey of asthma in chil-dren in 31 cities from September 2009 to August 2010. Non - asthmatic children,matched with the cases in age and gender,were selected during the same survey as control subjects if they were matched with the cases in age and sex. In-formation regarding the food allergen and symptom of food - induced anaphylaxis was analyzed. The difference in food allergy was compared between children with or without bronchial asthma. Results As a result,9235 asthmatic children and 11391 control subjects were enrolled in the case - control study. There were 14. 66％(1354 / 9235 cases)of the asthmatic children who had food allergy,compared to 3. 99％(455 / 11391 cases)of the non - asthmatics children, and the findings showed a significant difference (χ2 = 725. 25,P < 0. 001). The most common food allergens were fish and shrimp in both groups,and the difference was not significant [44. 09％ (597 / 1354 cases)vs. 42. 20％ (192 / 455 cases),χ2 = 0. 50,P > 0. 05]. The rate of peanut allergy was 4. 58％ (62 / 1354 cases)and 1. 54％ (7 / 455 cases) (χ2 = 8. 58,P < 0. 05),respectively. And the rates of fruit allergy in the asthmatic group and the non - asthmatic group were 14. 03％(190 / 1354 cases)and 27. 69％(126 / 455 cases)(χ2 = 44. 01,P < 0. 05),respectively. Cutaneous and nasal symptoms were common clinical manifestations. The rates of rash,pruritus,and swelling sympions were 47. 27％(640 / 1354 cases)and 61. 32％(279 / 455 cases)(χ2 = 26. 90,P < 0. 001),respectively for asthmatic group and non -asthmatic group. Rates of nasal symptoms were 17. 13％(232 / 1354 cases)and 10. 55％(48 / 455 cases)(χ2 = 11. 29, P = 0. 001),respectively in the asthmatic group and the non - asthmatic groups. Respiratory symptoms,such as cough and wheezing,were 25. 33％(343 / 1354 cases)and 5. 49％(25 / 455 cases)(χ2 = 80. 72,P < 0. 001)in 2 groups. Twenty cases of 1354 asthmatic children had severe food allergy,while such severe conditions occurred only 1 child without asthma (455 cases)occurred severe condition (1. 48％ vs. 0. 22％,χ2 = 4. 96,P < 0. 05). Conclusion The-rate of food allergen sensitization is highly prevalent in the children with asthma. Compared to those without asthma, and their types of food allergen and clinical symptoms are different from the latter.

Objective:To explore the clinical features, diagnosis and prognosis of renal transplant recipients with COVID-19.Methods:The clinical data were retrospectively analyzed for 2 kidney transplant recipients with COVID-19. Based upon clinical manifestations, blood routine, inflammatory factors, cell immunity, chest computed tomography(CT)and therapeutic efficacies, the diagnosis and treatment of COVID-19 in kidney transplant recipients(Interim Edition V)were compared to that of ordinary COVID-19 patients. Both recipients had an onset of low/moderate fever. There was no initial symptom of cough or fatigue. Blood routine indicated a normal count of leukocytes, a marked lymphocytopenia, elevated C-reactive protein(CRP)and slightly higher procalcitonin(PCT). Cellular immunity was extremely low and chest CT showed multiple patchy ground-glass opacities in both lungs.Results:After 1 week of onset, both patients had a marked disease progression. The pathogenesis and imaging changes were highly similar to those reported for ordinary COVID-19 patients. For preventing secondary infections, both received symptomatic supportive measures of antiviral agents, withdrawing immunosuppressants, tapering of hormone maintenance dose, intravenous drip of gamma globulin and respiratory supports. Currently the conditions of both patients obviously improved and renal function was stable. One case recovered and was discharged.Conclusions:The clinical manifestations of COVID-19 in renal transplant recipients are generally consistent with that of ordinary COVID-19 patients. Although there is no established treatment for COVID-19, withdrawing immunosuppressants, maintaining small and medium doses of hormones, actively restoring immunity and providing respiratory supports in a timely manner are effective.

Objective: To explore the clinical features, diagnosis and prognosis of renal transplant recipients with NCP. Method: The clinical data of 2 cases of kidney transplant recipients with NCP were retrospectively analyzed. Based onclinical manifestations, blood routine, inflammatory factors, cell immunity, chest CT andtherapeutic effects, the diagnosis and treatment of NCP in kidney transplant recipients (5th edition) were compared to that ofordinary NCP patients. Both recipients developed onset of low andmoderate fever, with no cough or fatigue at the initial stage. Blood routine indicated a normal range of leukocytes,buta significant decrease in lymphocyte counts, increased C-reactive protein (CRP) , and slightly higher procalcitonin (PCT) . The cellular immunity was extremely low, and the chest CT showed multiple patchy ground glass shadows in both lungs. Result: After 1 week of onset, both patients had significant disease progression. The pathogenesis and imaging changes were highly similar tothatreported in ordinary NCP patients.Two patients were givensymptomatic supportive treatment by antiviral agents, stop uses ofimmunosuppression agents, small amount of hormone maintenance, intravenous drip of gamma globulin andrespiratory support toavoid secondary infections. At present, the condition of both patients is obviously improved, and renal function is stable. One of them has recovered and was discharged. Conclusion The clinical manifestations of NCP in renal transplant recipients were generally consistent with that of ordinary NCP patients. Although there is no established method for the treatment of NCP, it is effective by stopping uses of immunosuppressive agents, maintaining small and medium doses of hormones, actively restoring immunity, and providing respiratory support in a timely manner.
