Clinical Observation on Therapeutic Effect of Huatan Jieyu Anshen Decoction Combined with Abdominal Vibration Tuina Manipulations on Chronic Insomnia in the Elderly / 广州中医药大学学报

Objective To investigate the therapeutic effect of Huatan Jieyu Anshen Decoction(mainly with the actions of resolving phlegm,relieving depression and calming mind)combined with abdominal vibration tuina manipulations on chronic insomnia in the elderly.Methods Ninety-four cases of elderly patients with chronic insomnia of phlegm-heat harassing the interior type were randomly divided into the observation group and the control group,with 47 cases in each group.The control group was given Huatan Jieyu Anshen Decoction orally,while the observation group was given oral use of Huatan Jieyu Anshen Decoction combined with abdominal vibration tuina manipulations.The course of treatment for the two groups lasted for 4 weeks.Before and after the treatment,the two groups were observed in the changes of traditional Chinese medicine(TCM)syndrome scores,Pittsburgh Sleep Quality Index(PSQI)score,Athens Insomnia Scale(AIS)score,Fatigue Scale-14(FS-14)score,World Health Organization Quality-of-Life Brief Scale(WHOQOL-BREF)score,and the serum levels of melatonin(MT),dopamine(DA),and cortisol(CORT).After treatment,the clinical efficacy of the two groups was evaluated.Results(1)After 4 weeks of treatment,the total effective rate of the observation group was 97.88%(46/47),while that of the control group was 87.23%(41/47),and the intergroup comparison(tested by chi-square test)showed that the therapeutic efficacy of the observation group was superior to that of the control group(P＜0.01).(2)After treatment,the scores of primary and secondary TCM symptoms in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease of the scores of primary and secondary TCM symptoms in the observation group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the PSQI scores,AIS scores,and FS-14 scores in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the WHOQOL-BREF scores were significantly increased compared with those before treatment(P＜0.05).The decrease of the PSQI scores,AIS scores and FS-14 scores as well as the increase of the WHOQOL-BREF scores in the observation group was significantly superior to that in the control group(P＜0.01).(4)After treatment,the serum MT level of both groups was significantly higher than that before treatment(P＜0.05),and the serum DA and CORT levels were significantly lower than those before treatment(P＜0.05).The increase in serum MT level and the decrease in serum DA and CORT levels of the observation group were significantly superior to those of the control group(P＜0.01).Conclusion The combined therapy of Huatan Jieyu Anshen Decoction combined with vibration tuina manipulations can achieve satisfactory efficacy in the elderly patients with chronic insomnia of phlegm-heat harassing the interior syndrome.The therapy is effective on regulating the central nervous system of the patients,improving the quality of the sleep,and promoting the relief of fatigue and the enhancement of the quality of life,which has great significance to the enhancement of the overall therapeutic efficacy of insomnia.

Impact on parents during hospitalisation for acute diarrhoea in young children

<p><b>INTRODUCTION</b>This study aimed to determine the emotional impact on parents of young children who require hospitalisation for acute diarrhoea (AD), and the disruption of daily activities experienced and costs incurred by them.</p><p><b>METHODS</b>A prospective study was conducted on children below two years of age with AD admitted to two urban hospitals in Malaysia. Parents were interviewed on the emotional impact and disruption of daily activities experienced by them, as well as the extra costs incurred as a result of the hospitalisation of their child.</p><p><b>RESULTS</b>The parents of 85 children (median age 13 months; boys n = 58, 68%; girls n = 27, 32%) were recruited for the study. The proportions of parents who reported that they were very worried about the symptoms of diarrhoea, vomiting and fever in their child were 82%, 83% and 78%, respectively. Parents also reported being upset, helpless, mentally and physically exhausted, and having experienced loss of sleep and disruption of daily routine during the hospitalisation of their child (median four days). The median extra cost (including out-of-pocket cost and loss of income) incurred by parents as a result of the hospitalisation was USD 252.86, which constituted 16% of the combined monthly family income.</p><p><b>CONCLUSION</b>Although short, AD-related hospitalisation in young children has considerable emotional impact and creates significant distress, in addition to causing significant financial burden for parents.</p>

Clinical features differentiating biliary atresia from other causes of neonatal cholestasis

<p><b>INTRODUCTION</b>This study determined any clinical features which may help to differentiate biliary atresia (BA) from other causes of neonatal cholestasis (NC).</p><p><b>MATERIALS AND METHODS</b>A prospective and observational study was conducted on consecutive infants with NC referred to the University of Malaya Medical Centre, Malaysia, between November 1996 and May 2004.</p><p><b>RESULTS</b>The 3 most common causes of cholestasis among the 146 infants with NC studied were idiopathic neonatal hepatitis (n = 63, 43%), BA (n = 35, 24%) and congenital cytomegalovirus hepatitis (n = 13, 9%). Common clinical features at presentation were jaundice (100%), hepatomegaly (95%), splenomegaly (52%) and pale stools (47%). Three clinical features noted to be sensitive for BA were the presence of acholic or variably acholic stools on admission, a liver which was firm/hard in consistency and a palpable liver of ≥4 cm (sensitivity of 77%, 80% and 94%, respectively), but the corresponding specificity was poor (51%, 65% and 39%, respectively). The stools of 2 children with BA were pigmented initially but became acholic subsequently.</p><p><b>CONCLUSIONS</b>We did not find any single clinical feature with sufficient sensitivity and specificity to differentiate BA from other causes of NC. Repeated inspection of stools colour is necessary as occasionally, patients with BA may have initial pigmented stools. Biochemical assessment and imaging studies are important in the assessment of any infant with NC.</p>

Apoptosis induction of rhesus peripheral blood lymphocytes / 南方医科大学学报

<p><b>OBJECTIVE</b>To establish a method for inducing apoptosis of rhesus peripheral blood lymphocytes (PBLs).</p><p><b>METHODS</b>Rhesus PBLs were irradiated with X-ray, (60)Co gamma-rays and ultraviolet (UVC254 nm), respectively, and the cell apoptosis was evaluated with flow cytometry using annexin-V staining and propidium iodide staining.</p><p><b>RESULTS</b>X-ray and (60)Co gamma-ray irradiation induced only low apoptotic rates of the PBLs, and UVC resulted in the highest apoptotic rate of about 60%. UVC irradiation of the PBLs in RPMI supplemented with 10% heat-inactivated fetal calf serum for 60 min at a distance of 20 cm led to an early apoptotic rate of 58.85% and necrotic rate of 11.5%. The apoptotic rate of PBLs increased in a dose- and time-dependent fashion.</p><p><b>CONCLUSION</b>For inducing apoptosis of the rhesus PBLs, UVC can be more effective than X-ray and (60)Co gamma-ray. The highest apoptotic rate can be achieved when the rhesus PBLs in RPMI supplemented with 10% heat-inactivated fetal calf serum are exposed to UVC for 60 min at the distance of 20 cm.</p>

Half-dose Zenapax for acute rejection prevention after renal transplantation / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the efficacy and safety of half-dose Zenapax for prevention of acute rejection after renal transplantation.</p><p><b>METHODS</b>According to the immunosuppressive regimen and renal function after transplantation, patients were divided into 4 groups, namely groups A, B, C, and D of 90, 73, 11 and 13 patients, respectively. Blood creatinine measured 1 week after operation was <176.6 micromol/L in groups A and B, and was >353 micromol/L in groups C and D. Patients in groups A and C were given 25 mg Zenapax (0.5 mg/kg) and MMF 0.75 g before operation, and those in groups B and D had only MMF of 0.75 g. All patients were given Pred, CsA and MMF after operation, and the rejection episodes, the time of acute rejection onset, the rate of rejection reversal and complications were analyzed in the time period of 6 months after operation.</p><p><b>RESULTS</b>After the operation, 13 patients (14.4%) developed acute rejection in group A, 18 (24.6%) in group B, 6 (54.5%) in group C and 7 (53.8%) in group D (P<0.01). The incidence of acute rejection in group B was significantly lower than that in groups C and D groups (P<0.01), and the latter two groups had similar incidence. The time of acute rejection onset ranged from 3 to 9 days postoperatively (mean 6.2-/+3.2 days) in group A, significantly delayed as compared with that in group B (range 2-8 days, mean 4.7-/+3.1 days), group C (range 2-7 days, mean 4.3-/+4.2 days) and group D group (range 2-9 days, mean 3.9-/+3.5 days), but the time was similar between groups B, C, and D (P>0.05). All acute rejection cases in group A was reversed, and the rate of reversal was 88.9% (16/18) in group B, 83.3% in group C, and 71.4% in group D. No significant differences were noted in such complications as infection, vascular injuries or gastrointestinal reactions between the 4 groups (P>0.05).</p><p><b>CONCLUSION</b>Zenapax at the dose of 25 mg can safely decrease the risk of acute rejection in patients with good postoperative renal function recovery, but dose not seem effective in patients with delayed graft function recovery.</p>
