Objective: To explore the clinical efficacy and mechanism of auricular point sticking plus Western medicine for moderate gastric cancer pain. Methods: A total of 80 patients were selected and divided into an observation group and a control group according to the random number table method, with 40 cases in each group. Patients in the control group received Western medicine treatment, while patients in the observation group received additional auricular point sticking. Both groups were treated for 2 weeks. Numeric rating scale (NRS) and Karnofsky performance status (KPS) were adopted before and after treatment. The total time and times of flare-up pain in 24 h were recorded. The cyclooxygenase-2 (COX-2) and tumor necrosis factor-α (TNF-α) levels were detected. The clinical efficacy of both groups was evaluated after treatment. Results: The total effective rate of the observation group was significantly higher than that of the control group (P<0.05); after treatment, NRS scores of both groups were significantly lower than those before treatment (both P<0.05), and the score of the observation group was lower than that of the control group (P<0.05); KPS scores of both groups were significantly higher than those before treatment (both P<0.05), and the score of the observation group was higher than that of the control group (P<0.05). After treatment, the total time and flare-up times of pain during 24 h of both groups were significantly reduced (all P<0.05), and those of the observation group were significantly less than those of the control group (both P<0.05). After treatment, the COX-2 and TNF-α levels of both groups were significantly reduced (all P<0.05), and were lower in the observation group than in the control group (all P<0.05). Conclusion: The clinical efficacy of auricular point sticking plus Western medicine for moderate gastric cancer pain is valid. This combined treatment can alleviate cancer pain and improve patients' quality of life, which may be related to its ability to reduce COX-2 and TNF-α levels.

Due to its effectiveness and specificity,RNA interference (RNAi) technology is widely used in the treatment of tumor,viral infectious and metabolic diseases.Noninvasively tracing the delivery of therapeutic RNA molecules in vivo and evaluating the therapeutic effects are important to promote the clinical application of RNAi technology.Molecular imaging allows noninvasive visualization of biological processes at the cellular and molecular level in vivo.It can be used to monitor the biodistribution of therapeutic RNA molecules and to assess the effects of the RNAi.This article reviews the advance of molecular imaging in monitoring the delivery of RNAi molecules and evaluating the therapeutic effects of RNAi.

Objective To observe the level of the nitric oxide (NO) and endothelin-1 (ET-1) in the exhaled breath condensate(EBC)and serum of the patients with ALI /ARDS, and investigate its clinical significance. Methods The study group included 52 mechanical ventilation patients with ALI/ARDS in ICU , which were divided into the survival and death group, while 30 healthy volunteers were recruited as healthy control. EBC samples of the healthy control and the study group on the 1st day and 5st day were collected by EcoScreen condenser with the synchronous collection of the venous blood. The concentrations of NO and ET-1 in the EBC and serum were measured by EIA. Results The levels of NO and ET-1 in EBC and serum of the patients with ALI /ARDS were all significantly higher than those of the healthy control. After treatment , the levels of NO and ET-1 in EBC and serum of the patients all decreased significantly compared with before treatment. After treatment , The levels of NO in EBC and serum of the survival group were significantly lower than those of the death group. After treatment , the levels of ET-1 in serum of the survival group was significantly lower than that of the death group. Conclusions Detecting the levels of NO and ET-1 in the EBC and serum can reflect oxidative stress , inflammatory reaction and endothelial injury in lung of patients with ALI/ARDS.

Objective To investigate the clinical features of primary Sj(o)gren syndrome (pSS) with interstitial lung disease (pSS-ILD) so as to raise the clinical diagnosis Level. Methods The clinical data were collected from 58 patients with pSS,who were admitted from March 2006 to March 2009. The patients were divided into ILD group (27 cases) and non-ILD group (31 cases). Rheumatoid factor(RF),C-reactive protein (CRP), protein electrophoresis and complement C3, C4 in serum were measured by immunoturbidimetric methods. Antinuclear antibodies (ANA) and anti-ENA antibodies were measured by indirect immunofluorescence technique and western blot. CA125 was detected by enzyme-linked immunosorbent assay and erythrocyte sedimentation rate (ESR) was detected by WS method. Pulmonaly function tests and radiology examination were performed. Results Compared with those in non-ILD group,the percentages of dry mouth,dry eye, rampant caries and velcro crackles were significantly higher in ILD group,anti-SSA antibody, ESR,CRP, CA125 and title of γ-gloulin was significantly higher in ILD group. In ILD group,diffusion dysfunction was 18 cases (66.7%),restricted ventilation dysfunction was 14 cases (51.9%),blocked ventilation dysfunction was 6 cases (22.2%), incorporated ventilation dysfunction was 8 cases(29.6%), forced vital capacity, forced expiratory volume in one second, maximum midexpiratory flow, DLCO were significantly lower in ILD group than those in non-ILD group (P ＜ 0.01). Moreover,high resolution computerized tomography (HRCT) was more sensitive than chest X-ray in the diagnosis of pSS-ILD.Conclusions The presence of pSS-ILD highly associates with the activity of pSS. Pulmonary diffusion ventilation function and HRCT play an important role in the diagnosis of pSS-ILD.

Objective To investigate the effect of Mannatide capsules and Thymic peptide on children with recurrent respiratory tract infections(RRI) and the influnence on their immunity. Methods 160 patients with recurrent respiratory tract infections were randomly divided into the control group and the treatment group,the treatment group were treated with Mannatide capsales and Thymic peptide while the control group with only the routine therapy. Results The effect of the treatment group was over the control one(P＜0.01),two groups of the patients were promoted on Ig level,and the effect of 160 cases in the treatment group was more obvious than that of the control one(P＜0.05). Conclusion Mannatide and Thyrnic peptide applied together are effective in treating children with recurrent respiratory tract infections.

AIM:To observed the variation regularity of corneal endothelial cells in patients with different diabetes duration after phacoemulsification, and investigate the effects of diabetes and its disease duration on corneal endothelial cells.
METHODS: Ninety-seven ( 135 eyes ) cataract patients with diabetes were selected randomly and divided into GroupⅠ( which diabetes duration ≥10a) and GroupII(which diabetes duration <10a) according to their disease duration. Additionally 62 (89 eyes) age-related cataract patients were randomly selected as the control group. The corneal endothelial cell density ( CD ) , proportion of hexagonal cell and coefficient of variation ( CV ) in the three group patients were measured respectively before phacoemulsification and after surgery. And the measurement results were statistically analyzed.
RESULTS:The corneal endothelial CD and proportion of hexagonal cell in the three group were decreased after surgery compared with preoperative. But the CV of corneal endothelial cells was increased on the 1 st wk and in 1st mo after surgery compared with the preoperative. The difference was statistically significant (P<0. 05). The corneal endothelial CD and proportion of hexagonal cell in the two diabetic groups were lower than the control group after surgery. However, the CV of corneal endothelial cells was higher than the control group. The difference was statistically significant ( P < 0.05 ) . There was no significant difference in the corneal endothelial CD, proportion of hexagonal cell and CV between the two diabetic groups before phacoemulsification (P>0. 05). The proportion of hexagonal cell in Group Ⅰ was lower than which in GroupIIafter surgery. While the CV was higher than which in Group II. The difference was statistically significant (P<0. 05).
CONCLUSION: Phacoemulsification has some damage on the corneal endothelial. Since the impact of diabetes on the morphology and function of corneal endothelial cell was related to the diabetic duration. So phacoemulsification has more obvious damage on the corneal endothelial in diabetic patients. And the diabetic duration was longer, the damage on the corneal endothelial in phacoemulsification was more easily.

Purpose:To investigate the prognostic factors f or local-regional control and survival in patients with regional lymph nodes re currence following mastectomy. Methods:Seventy-seven patients with their first recurrences in the regional lymph nodes treated during 1994-2003 were retrospectively analyze d. The recurrence were confined to supraclavicular region in 45 patients, in axi llary nodes in 16 patients, in internal mammary nodes in 6 patients, and with mo re than one lymph node region involved in 10 patients. The median follow-up was 34.4months. All patients were treated with radiotherapy to a total dose ranged from 50-74 Gy with a median dose of 60 Gy. Results:The median survival time was 4.67 years with 2-,5-an d 8- year survival rate of 77.8%,47.4% and 31.5% respectively. Disease-free i nterval, hormonal-receptor status were independent prognostic factors for survi val. Thirty patients had a second recurrence either in the original recurrent si te (4 patients) or in the other local-regional sites (26 patients). Chest-wall was the most frequently involved site for second recurrence, with 18 patients h ad a second recurrence including chest-wall, representing 23% of the whole coho rt. The axillary lymph nodes metastatic status of primary surgery was the only i ndependent prognostic factor for local control. Conclusions:Radiotherapy provides an efficient treatment for re gional lymph nodes recurrence following mastectomy. Twenty-three percent of pat ients present a second recurrence involving chest-wall, which suggests the sign ificance of an elective radiation to the chest-wall, especially in patients wit h 4 or more lymph nodes involved in primary surgery. Sub-group with a disease- free interval of more than 2 years, receptor positive has a better survival. The role of systemic treatment in the regional lymph nodes recurrent patients has n ot been established.
