Comparison of therapeutic effect of soft-tissue relaxing needling and electroacupuncture for knee osteoarthritis / 针刺研究

OBJECTIVE: To compare the clinical efficacy of soft-tissue relaxing needling and electroacupuncture (EA) in the treatment of knee osteoarthritis (KOA), so as to explore a new and more effective therapy for KOA. METHODS: Forty patients with KOA who met our diagnostic criteria were randomly and equally divided into acupuncture group and soft-tissue relaxing needling (relaxing-needling) group. EA (20 Hz, a tolerable strength and duration of 20 min) was applied to the unilateral Neixiyan(EX-LE5) and Waixiyan(EX-LE5), and manual acupuncture stimulation was applied to Heding(EX-LE2), Xuehai (SP10), Xiyangguan (GB33), Liangqiu(ST34), Yanglingquan(GB34) and Yinlingquan(SP9) on the affected side by using uniform reinforcing-reducing technique. In the relaxing-needling group, after identifying the tender point and nodule-like or stiff-strip-muscle spot at the affected limb by palpation, we used filiform needles to insert into them, then, made a longitudinal separation or point-like pricking. The visual analog scale (VAS) pain score, knee flexion activity (range of motion, ROM), and the knee osteoarthritis severity (Lequesne index, composed of daily living, walking distance and pain) were measured before and after the treatment. The therapeutic effect was assessed by consulting the Guiding Principles for Researching New Drugs of Traditional Chinese Medicine (2002) and Criteria for Diagnosis and Assessment of Therapeutic Effect of Syndromes or Illnesses of Traditional Chinese Medicine (1994). RESULTS: After the treatment, the VAS score and Lequesne index were significantly decreased in both acupuncture and relaxing-needling groups (P0.05)．. CONCLUSION: Both relaxing-needling and EA therapies are comparable in the therapeutic effect for KOA, and the former is superior to the latter in reducing the joint pain and improving the knee joint locomotor function, thus being worthy of clinical application.

Benign infantile convulsions associated with mild gastroenteritis: a clinical analysis and follow-up study / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the clinical features and prognosis of benign infantile convulsions associated with mild gastroenteritis (BICE).</p><p><b>METHODS</b>A retrospective analysis was performed for the clinical data of 436 children with BICE, and among these children, 206 were followed up for 1.5 to 7 years. Some parents were invited to complete the Weiss Functional Defect Scale to evaluate the long-term social function.</p><p><b>RESULTS</b>The peak age of onset of BICE was 13-24 months, and BICE had a higher prevalence rate in September to February of the following year. Convulsions mainly manifested as generalized tonic-clonic seizures, which often occurred within 24 hours after disease onset and lasted for less than 5 minutes each time. Sometimes they occurred in clusters. During the follow-up of 206 children, only one had epileptiform discharge, and the other children had normal electroencephalographic results. The parents of all the 206 children thought their children had normal intelligence and had no marked changes in character. Based on the Weiss Functional Defect Scale completed by the parents of some BICE children, there was no significant difference in the long-term social function between BICE children and healthy children matched by age and sex.</p><p><b>CONCLUSIONS</b>BICE mainly occurs in children aged 1-2 years, with the manifestation of transient generalized seizures in most children and cluster seizures in some children. BICE seldom progresses to epilepsy and has good prognosis.</p>

Lower respiratory tract infection caused by influenza virus A and influenza virus B in Wenzhou, China: a clinical analysis of 366 children / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To compare the epidemiological and clinical features of lower respiratory tract infection (LRTI) caused by influenza virus A (IVA) and influenza virus B (IVB) in children.</p><p><b>METHODS</b>The clinical data of 366 children with LRTI caused by influenza virus (IV), who were hospitalized in Yuying Children′s Hospital of Wenzhou Medical University between 2010 and 2014, were analyzed retrospectively, and there were 272 cases caused by IVA and 94 cases caused by IVB.</p><p><b>RESULTS</b>IV was mainly prevalent from December to March of the next year, with the predominance of IVA. There were small peaks of IVA prevalence in July or September every other year, and IVB was prevalent from December to March of the next year every other year. The children with LRTI caused by IVA alone had a significantly higher white blood cell (WBC) count and significantly higher percentages of children with increased WBC, abnormal serum sodium, and abnormal serum potassium than those caused by IVB alone (P<0.05). However, there were no significant differences in age, sex, underlying diseases, clinical manifestations, and co-infection rate with bacteria or atypical pathogens between the two groups (P>0.05). The rate of co-infection with respiratory syncytial virus (RSV) was significantly higher in the IVB group than in the IVA group (P<0.01).</p><p><b>CONCLUSIONS</b>IVA is prevalent in winter and spring every year and has small peaks in summer every other year, while IVB is prevalent in winter and spring every other year. Compared with IVB, IVA causes more cases of increased WBC and electrolyte disturbance. The children infected with IVB are more likely to be co-infected with RSV. The children with LRTI caused by IVA and IVB have similar clinical manifestations.</p>

Blood hemoperfusion with resin adsorption combined continuous veno-venous hemofiltration for patients with multiple organ dysfunction syndrome / 世界急诊医学杂志（英文）

BACKGROUND: Blood hemoperfusion with resin adsorption can clean larger molecules that exceed the molecular weight cutoff of combined continuous veno-venous hemofiltration (CVVH). Hence blood hemoperfusion with resin adsorption combined CVVH (HP+CVVH) has higher ability of mediator clearance, and can improve clinical outcomes in theory. This study aimed to investigate the effect of blood hemoperfusion with resin adsorption combined continuous veno-venous hemofiltration (HP+CVVH) on plasm cytokines like TNF-α, IL-1β, IL-6, cellular immunity and prognosis in patients with multiple organ dysfunction syndrome (MODS). METHODS: This was a prospective, randomized clinical trial. A total of 30 patients who had been diagnosed with MODS were enrolled in this study. Patients were randomly allocated to routine treatment+HP+CVVH group (treatment group) and routine treatment+only CVVH group (control group). In the treatment group, patients received blood hemoperfusion with resin adsorption for 2 hours, and then received CVVH for 10 hours every day. In the control group, patients received CVVH for 12 hours only every day. The patients in the two groups received blood purification therapy for three days. The plasma of patients in the treatment group was obtained at 0, 2, 12, 24, 26, 36, 48, 50, 60 hours, 5th day, 7th day and 10th day, respectively. The plasma of patients in the control group was obtained at 0, 12, 24, 36, 48, 60 hours, 5th day, 7th day and 10th day, respectively. APACHE II score, T-lymphocytes subpopulations, blood lactate acid concentration, heart rate, breathing rate, and oxygenation index were observed. RESULTS: Plasma cytokines like TNF-α, IL-1β, IL-6 decreased markedly after HP (P<0.01);T-lymphocytes subpopulations CD3+, CD4+, CD8+, CD4+/CD8+ increased after HP+CVVH or only CVVH. The plasma concentrations of TNF-α, IL-1β and IL-6 in the two groups were not markedly different at 12, 36, and 50 hours. But on the 5th day, the plasma concentrations of TNF-α, IL-1β and IL-6 in the treatment group were lower than those in the control group (P<0.05). On the 28th day, 5 patients died in the treatment group, and 6 patients in the control group. CONCLUSIONS: Both HP+CVVH and CVVH can clean plasma cytokines like TNF-α, IL-1β, and IL-6, and improve cellular immunity and clinical symptoms and signs of patients. Compared with only CVVH, the plasma concentrations of TNF-α, IL-1β and IL-6 were lower on the 5th day, and patients have an increased survival rate on the 28 day in the HP+CVVH group.

Effects of dexamethasone on 15-lipoxygenase expression in lungs of asthmatic rats / 中国当代儿科杂志

<p><b>OBJECTIVE</b>15-lipoxygenase (15-LO) is a prooxidant enzyme which is expressed in asthmatic lungs leading to formation of pro- and anti-inflammatory mediators. Gene expression profiling studies show the association between 15-LO and allergic asthma. This study was designed to observe the expression of 15-LO in lungs of asthmatic rats and examine the effects of dexamethasone on 15-lipoxygenase expression.</p><p><b>METHODS</b>Twenty-seven male Sprague-Dawley (SD) rats were randomly divided into three groups: control, asthma and dexamethasone (DXM) intervention. An asthma model was prepared by sensitization and challenging with ovalbumin. The production of 15-LO in lung tissue homogenates was measured using ELISA.The expression of 15-LO mRNA in lungs was determined by reverse transcription-polymerase chain reaction (RT-PCR).</p><p><b>RESULTS</b>The levels of 15-LO mRNA and protein in the asthma group (0.51 ± 0.14 and 2080 ± 73 μg/mL, respectively) were lower than those in the control group (0.76 ± 0.15 and 2472 ± 106 μg/mL, respectively; P<0.01). DXM intervention increased significantly the levels of 15-LO mRNA and protein (1.02 ± 0.34 and 2562 ± 218 μg/mL) compared with the asthma group (P<0.01).</p><p><b>CONCLUSIONS</b>The production of 15-LO in lung tissues is reduced in asthmatic rats. DXM can increase the expression of 15-LO in lung tissues and thus might provide anti-inflammatory effects in asthmatic rats.</p>

Changes in urotensin-II expression in airway remodelling in asthmatic rats / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the role of urotension-II in serum and bronchoalveolar lavage fluid (BALF) in the process of airway remodelling in asthmatic rats.</p><p><b>METHODS</b>Thirty-two male Sprague-Dawley (SD) rats were randomly divided into normal control and 2-week, 4-week and 8-week asthmatic groups (OVA inhalation of 2, 4 and 8 weeks respectively). Rats were sensitized and challenged by OVA to establish a model of asthma. The bronchial wall thickness and the airway smooth muscle thickness were measured by image analysis system. The urotension-II contents in serum and BALF were determined using ELISA.</p><p><b>RESULTS</b>The bronchial wall thickness and the airway smooth muscle thickness in the three asthmatic groups significantly increased compared with those in the normal control group (P<0.01). The urotension-II contents in serum and BALF in the three asthmatic groups also increased significantly compared with those in the normal control group (P<0.01). The urotension-II contents in serum and BALF in the 8-week asthmatic group were the highest, followed by the 4-week and the 2-week asthmatic groups (P<0.01). BALF urotension-II contents were positively correlated with the bronchial wall thickness and the airway smooth muscle thickness as well as serum U-II contents in the four groups.</p><p><b>CONCLUSIONS</b>The urotension-II contents in serum and BALF in the process of airway remodeling increase in asthmatic rats. The changes in serum and BALF urotension-II contents may be associated with airway remodeling in asthmatic rats.</p>
