OBJECTIVE: To observe the effect of heat-sensitive moxibustion combined with medication on orthostatic hypotension (OH) of yang -qi deficiency in the elderly. METHODS: Sixty elderly patients with OH of yang -qi deficiency were randomly divided into an observation group (30 cases, 1 case dropped out) and a control group (30 cases). The patients in the control group were treated with oral midodrine hydrochloride tablets, 2.5 mg each time and twice daily, while the patients in the observation group were treated with heat-sensitive moxibustion in addition to the treatment in the control group. Acupoints selected included Dazhui (GV 14), Fengfu (GV 16), and Baihui (GV 20), with each session lasting 30-40 min, once daily. Both groups were treated for 4 weeks. Blood pressure in the supine and standing positions, as well as the decrease of blood pressure when the position changing from supine to standing, were measured before treatment and after 2 and 4 weeks of treatment. Clinical efficacy was also evaluated. RESULTS: After 4 weeks of treatment, both groups showed an increase in systolic blood pressure (SBP) and diastolic blood pressure (DBP) in both the supine and standing positions (P<0.05), and the decrease in SBP and DBP when the position changing from supine to standing was reduced (P<0.05). Compared with the control group, the observation group had higher SBP and DBP in both positions and a smaller decrease in SBP and DBP when the position changing from supine to standing (P<0.05). The total effective rate was 96.6% (28/29) in the observation group, which was higher than 70.0% (21/30) in the control group (P<0.05). CONCLUSION Heat-sensitive moxibustion combined with medication could increase the blood pressure in both supine and standing position, and decrease the reducing of blood pressure when the position changing from supine to standing in elderly patients with OH of yang-qi deficiency.

Objective To investigate the efficacy and application of bronchoalveolar lavage in chil-dren with severe pneumonia undergoing mechanical ventilation. Methods Using a prospective randomized controlled clinical study, 202 children with severe pneumonia received mechanical ventilation in Hunan Children′s Hospital from January 2016 to January 2018 were selected as the subjects. According to the digital method,all cases were divided into treatment group (101 cases) and control group (101 cases) randomly. The patients in the control group were given conventional treatment ( anti-infection and symptomatic thera-py) . The treatment group was treated with bronchoalveolar lavage on the basis of conventional treatment. The basic situation,the respiratory function before and after the treatment,the inflammation index,the curative effect and the prognosis of two groups were analyzed. Results There were no significant differences between the two groups in gender,age,course pre-admission,pediatric critical illness score,respiratory function and in-flammation index ( P>0. 05 ) . The respiratory function indexes of the treatment group were obviously im-proved 2 hours after the treatment and the PaO2 ,PaO2/FiO2 and SaO2 were significantly higher than those of the control group[PaO2:(82. 4 ± 6. 4) mmHg(1 mmHg=0. 133 kPa) vs. (74. 0 ± 5. 5) mmHg, PaO2/FiO2:(360. 2 ± 21. 3) mmHg vs. (332. 6 ± 23. 5) mmHg,SaO2:(94. 9 ± 8. 2)％ vs. (88. 6 ± 10. 3)％], while the PaCO2 were significantly lower than the control group [ ( 37. 3 ± 10. 3 ) mmHg vs. ( 45. 8 ± 5. 5 ) mmHg],and the differences were statistically significant (P<0. 05). Five days after treatment,the WBC, PCT and CRP of treatment group were significantly lower than those in the control group[WBC:(8. 5 ± 2. 4) × 109/L vs. (11. 7 ± 3. 5) × 109/L,PCT:(1. 2 ± 0. 7) μg/L vs. (2. 3 ± 0. 9) μg/L,CRP:(9. 1 ± 3. 2) mg/L vs. (16. 5 ± 4. 7) mg/L,P<0. 05,respectively]. The total effective rate in the treatment group was significantly higher than that in the control group[93. 1％(94/101)vs. 81. 2％(82/101)]. Mechanical venti-lation duration and PICU stay in treatment group were significantly shorter than those in the control group [(148. 5 ±30. 6)h vs. (159. 6 ±47. 3)h,(220. 8 ±49. 7)h vs. (330. 7 ±94. 6)h]. The positive rate of patho-genic bacteria was significantly higher than that in the control group [79. 2％(80/101)vs. 62. 4％(63/101), P<0. 05],but there was no significant difference in the 28 days mortality of the two groups[5. 0％(5/101) vs. 5. 9％(6/101),P>0. 05]. Conclusion The bronchoalveolar lavage can improve the respiratory func-tion,reduce the inflammatory reaction,shorten mechanical ventilation duration and PICU stay in children with severe pneumonia undergoing mechanical ventilation obviously. It is worth popularizing in the PICU because of the improvement of curative effect in these children.

Objectives To investigate the effects of ethanol on neural development and kainate receptor expression in young mice. Methods Fetal alcohol spectrum disorder model was established by administration of 20% ethanol solu?tion to 7-day-old Kunming mice and control animals received physiological saline (The number of treatment and control were 80 and 40, respectively ). Body weight and general biological features were observed every day. Morris water maze was used to test learning and memory ability. Fluoro-Jade B was used to examine neural cells 24 hours after treatment in additional thirty 7-day-old Kunming mice which were further divided into two groups:a treatment group receiving 20%ethanol solution (n=15) and a control group receiving physiological saline (n=15). The development of neural cells and expression levels of kainite receptors were examined by using immunofluorescence staining. Results The body weight was significantly lighter in treatment group than in control group(control:21.13 ± 1.72g,treatment:13.96 ± 2.98g,P<0.05). Morris test showed that model group had longer latency than control group to find hidden platform(control:21.05± 5.31s,treatment:34.15±3.26s,P<0.05). Spatial probe test revealed that the number of passing through the platform were significantly smaller in model group than in control group(control:2.70 ± 1.25 times,treatment:0.93 ± 0.80 times,P<0.05). Astrocyte development anomaly was evident after ethanol treatment for 7 days. The expression levels of kainite re?ceptor GluR-6 and KA2 were up-regulated in the CA region of the hippocampus after ethanol treatment for 7 days. Con?clusion Kainite receptor GluR-6 and KA2 in CA region of the hippocampus may contribute to ethanol-induced hippo?campal neural development anomaly.

Objective To observe the effect of the nutrition management according to the JCI(Joint Commission on Accreditation of Healthcare Organizations)management standard for critically ill pediatric patients with mechanical ventilation.Methods A total of 330 cases with mechanical ventilation were en-rolled in the control group from Hunan Province Children's Hospital PICU between Jan.2012 and Dec.2012, and these pediatric patients were managed with the conventional nutrient management.A total of 359 pediatric patients with mechanical ventilation were admitted to the experimental group from Jan.2013 to Dec.2013 and these patients were managed with nutrient management based on JCI standards.The length of mechanical venti-lation,stay in ICU,stay in hospital were compared between two groups,and the incidence of ventilator-associ-ated pneumonia,abandonment rate and mortality were also compared between experimental group and control group.Results The length of mechanical ventilation in control group[(8.39 ±1.34)days]was longer than that of experimental group[(5.69 ±1.12)days].The length of stay in PICU for control group[(12.32 ± 1.37)days]was more than that in experimental group[(9.42 ±1.53)days].The length of stay in hospital for control group [(15.37 ±2.16 )days]was higher than that of experimental group [(12.63 ±2.29 ) days].The incidence of ventilator-associated pneumonia(9.7%)in control group was higher than that of ex-perimental group,and the giving up or mortality rate in control group(8.48%)was higher than that of exper-imental group(4.35%).And there were significant differences by statistical analysis(P ﹤0.01 ,respective-ly).Conclusion According to the nutritional management in JCI standard,the length of mechanical ventila-tion,stay in PICU and stay in hospital time,the incidence of ventilator-associated pneumonia,and the aban-doned or mortality rate were reduced for critically ill pediatric patients with mechanical ventilation.

Objective To evaluate the application of echocardiography in the diagnosis of bicuspid aortic valve and its pathophysiologic development and to demonstrate the degree of aortic valve dysfunction. Methods The echocardiographic characteristics and clinical data were analyzed retrospectively in 135 patients with bicuspid aortic valve to demonstrate the variation of aortic valve dysfunction in the progression of the course of the disease. Results Isolated aortic regurgitation was present in 68 (50%) patients, 19 (14%)patients had isolated aortic stenosis and 29 (22%)patients had combined aortic stenosis and regurgitation, 19 (14%) patients had neither stenosis nor regurgitation. Aortic regurgitation were all more commen within each age group, aortic regurgitation were also more commen within each age group in patients in their advanced course who went to surgical treatment. Conclusions Echocardiography is an effective method in the early diagnosis of aortic valve dysfunction.

BACKGROUNDFUS2 gene locating at 3p21.3 is considered a promising candidate tumor suppressor gene. The aim of this study is to examine the difference in FUS2-767A/T polymorphism site between lung cancer patients and normal controls in Chinese population.

METHODSThe genotype FUS2-767A/T was detected in 146 lung cancer patients and 113 normal controls by PCR-SSCP method. The relationship between lung cancer risk and difference in genotypes of FUS2 gene was analysed.

RESULTSFUS2-767A/T was significantly related to histological type (P=0.044), age of the patients with lung cancer (P=0.011) and vessel cancer embolus (P=0.031) in lung cancer group. There was no significant difference in distribution of FUS2 genotypes between lung cancer patients and normal controls (P=0.945).

CONCLUSIONSThe results suggest that the FUS2-767A/T polymorphism may be a susceptibility factor for lung cancer among Chinese population.

Carcinoid tumors are relatively rare neuroendocrine malignancies most commonly originating from enterochromaffin cells in the gastrointestinal tract.Carcinoid syndrome occurs when tumor cells metastasize to the liver,as the vasoactive substances produced are able to reach the systemic circulation via the hepatic vein.The development of carcinoid heart disease (CHD) is thought to be related to the vasoactive substances secreted by the metastatic tumor cells in the liver,reaching the right heart.This is associated with deposition of fibrous tissue on the endocardial surfaces of the heart.Several series have reported CHD in up to 70% of cases of carcinoid syndrome.Somatostatin analogue use is a therapeutic cornerstone,effective in symptomatic control of the endocrine syndrome.In patients with severe cardiac involvement and well-controlled systemic disease,valve replacement surgery is an effective treatment modality that can relieve intractable symptoms and contribute to improved outcome.
