Objective To explore whether the Kang Kefei and Tian Runmei′s diagnostic criteria (K-T criteria) is suitable for atopic dermatitis(AD). Methods 917 AD patients, whose diagnosis had been made with the Hanifin and Rajka criteria (H-R criteria) previously, were redignosed by K-T criteria. Their atopic history, and clinical fealures were analysed, too. Results 888 out of 917 patients(96.84%) were consistent with K-T criteria.763 patients (83.21%) had personal or family atopic history. The frequency of facial dermatitis was higher in infantile AD group than that in childhood AD group, adolescence AD group, and adult group. Whereas,the frequency of xerosis,ichthyosis,keratosis pilaris and orbital darkening was lower in infantile AD group than those in other groups. Conclusion Atopic history is an important factor in the diagnosisof AD. K-T criteria is practical and of value in the diagnosis of AD.

Objective To discuss the efficacy and relative factors that affect the sequential therapy of invasive and non-invasive mechanical ventilation in treating severe respiratory failure.Methods We analyzed the clinical data of the patient who was hospitalized in Respiratory Department of the Sixth Hospital of Luohe on 3th February 2008.Results The patient received invasive mechanical ventilation for 4 days,then changed to mask non-invasive positive pressure ventilation for 10 days,while receiving comprehensive treatment of anti-infection and bronchial expansion,etc.Then the patient was recovered.Conclusion The sequential therapy of invasive and non-invasive mechanical ventilation in treating severe respiratory failure is effective.The efficacy depends on the optimum converting time between invasive and non-invasive mechanical ventilation,the choice of ventilator and the patient′s compliance.

Objective To investigate the serum levels of CXC, CC and C chemokines, and to esti-mate the relationship among the three kinds of chemokines as well as that between these chemokines and other Th1 and Th2-related cytokines, in patients with atopic dermatitis (AD). Methods Fifty-one patients with atopic dermatitis, including 35 males and 16 females with an average age of 17 years and disease course of 13.6 years were enrolled into this study together with 34 normal human controls. ELISA was used to measure the serum levels of monokine induced by IFN-γ (Mig), thymus and activation-regulated chemokine (TARC), cutaneous T cell-attracting chemokine (CTACK) and lymphotactin (Ltn) in these subjects. Severity of AD was assessed according to SCORAD. Results The serum levels were 79.6±28.0 ng/L for Mig, 349.9±91.5 ng/L for TARC, 747.4±359.4 ng/L for CTACK and 141.0±68.4 ng/L for Ltn in patients, significantly higher than those in the normal controls (63.8±26.5 ng/L, 219.4±82.1 ng/L, 294.3± 64.9 ng/L, 80.9±54.2 ng/L, P < 0.05, 0.01, 0.01, 0.01 respectively). A significant correlation was observed between the serum level of CTACK and SCORAD score in patients (r = 0.343, P < 0.05). Similarly, the percentage of body surface area (BSA) involved positively correlated with the serum levels of Mig, TARC, CTACK and Ltn. Furthermore, there was a significant correlation between the serum level of Ltn and TARC (r=0.444, P< 0.01) as well as CTACK (r=0.572, P< 0.01), between that of CTACK and TARC (r=0.524, P< 0.01), and between that of TARC and Mig (r=0.313, P< 0.05). Conclusion The CXC, CC and C chemokines might be involved in the pathogenesis of AD. Further more, CTACK level could serve as a good indicator for the severity of AD.

BACKGROUND: Parkinson disease (PD) not only influences motor function, also affects sensation and cognition. Treatment with dopamine can only control symptom and has well side effect; however, yichan tang has great effect on treating PD in clinic.OBJECTIVE: To observe the effect of yichan tang on praxiological behavior, catecholamines substance in cerebral tissue and substantia nigra nerve cells of PD rats and analyze its effective mechanism.DESIGN: Randomized control animal study and single-blind evaluation.SETTING: Department of Traditional Chinese Medicine of General Hospital of Chinese PLA.MATERIALS: A total of 120 female SD rats weighing 180-200 g were selected in this study. Seventy modeling PD rats were randomly divided into saline group (n=30) and yichan tang group (n=40) according to digital table. Another 30 non-modeling rats were regarded as normal control group. Yichan tang was made of 15 g shanyurou, 15 g shichangpu, 10 g xianlingpi, 10 g roucongrong, 15 g gouqizi, 15 g danshen and 8 g wugong,etc., and provided by Dispensary of Chinese herb of General Hospital of Chinese PLA. Drug was decocted for 30 minutes to filter the solution and then concentrated into decoction including 1.0 g/mL raw materials.METHODS: The experiment was carried out at the Animal Laboratory of General Hospital of Chinese PLA from September to December 2001. PD rat model were established with 6-hydroxy-dopa to observe behavior of rats.The administration of rats (body mass/kg) in yichan tang group was 10 times as the administration of the adults (60 kg) (5 g/kg). Rats were perfused once a day and weighted once a week. The dosage of administration was regulated as the body mass changing, and the administration lasted for 8 weeks. Rats in saline group and normal control group were perfused with the same volume of saline as the criteria of body mass. Rotatory behaviors of rats in normal group, saline group (model group before administration)and yichan tang group were observed before administration and at 5, 6, 7 and 8 weeks after administration. Changes of content of catecholamines in extracellular fluid of cerebral tissue were measured with micro-dialysis technique and high performance liquid chromatography (HPLC), meanwhile, changes of substantia nigra nerve cells on both sides of corpus striatum were observed under 20-time and 40-time optic microscopes.MAIN OUTCOME MEASURES: Effect of yichan tang on medium of cranial nerve of PD rats; changes of substantia nigra nerve cells on both sides of corpus striatum with optic microscope and electron microscope; evaluation of yichan tang.RESULTS: Among 100 rats, 6 rats in yichan tang group died because of failure perfusion, 5 in saline group and 2 in normal control group. Therefore, 87 rats were involved in the final analysis. ① At 5, 6, 7 and 8 weeks after treatment, rotatory times within 40 minutes were all shorter in yichan tang group than those in saline group [(112.34±33.36), (91.16±73.06),(72.05±20.77), (61.63±17.93), (340.90±52.97) times, P ＜ 0.01]. ② Levels of 3,4-dihydroxybenzene acid, homovanilic acid, dopamine and 5-serotonin on the injured side were lower than those on the uninjured side (P ＜ 0.05-0.01). After treatment, levels of mediums mentioned above were higher in yichan tang group than those in saline group (P ＜ 0.05-0.01); however,there were no significant differences of mediums on the uninjured side in the three groups (P ＞ 0.05). ③ Pathological observation: Amount of substantia nigra nerve cells on the injured side was more in yichan tang group than that in saline group; moreover, volume of neurons was full, structure was clear, and values of Golgi complex and mitochondria were close to the normals.CONCLUSION: Yichan tang can relieve injured degrees of substantia nigra nerve cells, facilitate the repair, increase the content of endogenetic catecholamines in cerebral tissue, and improve rotatory behavior of PD rats.

Objective To investigate the feasibility and safety of laparoscopic-assisted gastrectomy for distant gastric cancer.Methods All 18 patients with distant gastric cancer receiving laparoscopic-assisted gastrectomy were analyzed.Results Laparoscopic-assisted distal gastrectomy was performed successfully in all patients.The mean operation time was(291.33?19.61) min.The mean blood loss was(151.32?71.78) ml.The mean numbers of harvested lymph node were 14.57?3.11.The mean time of gastrointestinal function recovery was(3.46?0.93) d,the mean out of bed activity time was(1.75?0.45) d.All patients were followed up for 1-24 months,mean 11 months.No local recurrence,trocar implant or distant metastasis happened.Conclusion Laparoscopic-assisted gastrectomy is a feasible and safe surgical procedure combined with minimal trauma and fast recovery.

Objective To investigate the aberrant methylation and expression of growth arrest and DNA-damage-in-ducible 45 gamma (GADD45G) gene in gastric cardia adenocarcinoma (GCA). Methods Bisulfite conversion-methylation specific polymerase chain reaction method (BS-MSP) and immunohistochemistry method were used respectively to detect the methylation status and protein expression of GADD45G in 138 GCA tumor tissues and corresponding normal tissues. Re-sults The methylation status of GADD45G distal promoter (region 1) was not detected in GCA tumor tissues and corre-sponding normal tissues. For GADD45G region 2 and region 3, the BS-MSP results of region 3 were identical to that of re-gion 2. The methylation frequency of proximal promoter and exon 1 in GADD45G island 2 (region 2 and region 3) in GCA tu-mor tissues (49.3%, 68/138) was significantly increased compared to that in corresponding normal tissues (0, P＜0.01). The methylation status of this two sites in tumor tissues was associated with TNM stage of tumors (P＜0.05). The protein expres-sion of GADD45G in tumor tissues was significantly decreased than that in corresponding normal tissues (P ＜ 0.05),and threre was a significant negative correlation with methylation status of GADD45G proximal promoter and exon 1 (rs=-0.398). Conclusion The decreased expression of GADD45G by hypermethylation of proximal promoter exon 1 of the gene may play an important role in gastric cardia adenocarcinoma.
