AIM: To observe the clinical effects of moisturizing eye decoction combined with artificial tears in the treatment of ophthalmoxerosis.METHODS: A randomized controlled clinical research method was employed.One hundred-sixty patients diagnosed with ophthalmoxerosis were equally divided into a treatment group and a control group.In the treatment group,patients were given one dose per day of the moisturizing eye decoction as well as artificial tear drops three times a day.The patients in the control group were treated with artificial tears drops three times a day.The course of treatment was 3mo.Dry-eye symptoms,tear break-up time(BUT) by the slit lamp,the time of tear secretion (Schirmers Ⅰ test),corneal fluorescein staining (FL),and curative effects were observed before treatment as well as in the first and third months after treatment.RESULTS: There were no significant differences between the two groups in terms of BUT,SⅠt,and FL before treatment (P>0.05).After treatment in the first and the third months,the BUT,SⅠt,FL,and curative effects were significantly different between the two groups (P<0.05).CONCLUSION: Moisturizing eye decoction combined with artificial tears in the treatment of ophthalmoxerosis can improve efficacy.

Objective To investigate the expression pattern of skeletal muscle specific miR-206,myogenesis related myoD which change with time in dcnervated muscle atrophy rats.Methods From June,2015 to January,2016,40 SPF sprague-dawley rats were equally classified into 5 groups randomly according to standard settled before,5 groups were separately defined as denervated 0d group,denervated 1d group,denervated 7d group,denervated 14d group,and denervated 28d group.Each group contained 8 rats.The rats atrophy models were established by cutting sciatic never on left side.According to the different denervated time,the gastrocnemii on both sides were obtained under anesthesia,respectively.The wet weight ratio of two compared gastrocnemii were measured,and the gastrocnemii transection was observed by HE stain,measured the expression of myoD protein by western blot,obtained the expression of miR-206,myoD mRNA by qPCR.Results According to our study on rats denervated atrophy models,the wet ratio of compared gastrocnemius would decrease rapidly,by HE stain,decease of cross sectional area in muscle fiber was observed as well as degeneration.Collagen fibers hyperplasia appeared and increased with time change.Wet ratio and transaction aera ratio of group Od,1d,7d,14d,28d were 0.99±0.04,0.92±0.07,0.68±0.11,0.39±0.06,0.27±0.07 and 0.99±0.02,0.96±0.04,0.51±0.09,0.34±0.08,0.23±０.03 respectively,difference between experimental groups and control group were statistically significant (P＜ 0.05),the differences between each experimental groups were also statistically significant (P＜ 0.05).After qPCR test of miR-206,myoD mRNA expression,it was found that their expression patterns were similar,miR-206,myoD mRNA increased at first and would reach the expression peak at the 7 th day,after that their contents decreased but still higher at the 14th day when compared with that at the 1 st day.Their expression of group 0d,1 d,7d,14d,28d were 0.24±0.06,0.34±0.04,0.68±0.04,0.49± 0.07,0.25±0.03 and 0.41 ±0.06,0.49±0.09,0.93±0.06,0.66±0.03,0.39±0.04,respectively.All experimental groups were statistically significant different when compared with 0d group except 1d group (P＜ 0.05),the differences between each experimental groups were also statistically significant(P＜ 0.05).The protein expression of myoD was also measured by western blot test,which showed nearly the same expression pattern as the mRNA expression pattern.After injury,the protein expression increased and reached the expression peak at the 7th day.The relative expression of myoD of group 0d,1d,7d,14d,28d measured by grey ratio were 1.03±0.05,1.06±0.06,1.42±0.10,0.66±0.13,0.24±0.07,respectively.The difference between experimental groups and control group were statistically significant (P ＜ 0.05),the differences between each experimental groups were statistically significant (P ＜ 0.05) as well.Conclusion The degree of muscle denervation atrophy was related to the denervated duration in rats.The expression regulation of miR-206 and myoD in gastrocnemius was similar during the muscle denervation atrophy,which suggesting having internal relationship between miR-206 and myoD.

A new embedded telemetry system for potentiometric sensors was developed. The system consisted of a transmitter unit, a receiver unit and a personal computer ( PC) . The transmitter unit included a current amplifier, a∑-Δanalog-to-digital converter ( ADC) , a microcontroller unit ( MCU) and a radio module. The receiver unit was composed of a radio module, a microcontroller unit and a serial-to-USB converter module. The receiver unit was connected to an upper computer via a universal serial bus ( USB ) . The embedded software written in C language controlled the signal acquisition and transmission. The computer software written in LabVIEW language was used for data storage and display. The range of the acquisition voltages was from-1. 17 V to +1. 17 V. In order to verify the accuracy and reliability of this system, a control experiment had been done with this system and a digital multimeter. Moreover, a response test of acidity changes had been done with the self-made H+ selective electrode. The results showed that the accuracy of this system could be up to 0. 1 mV and it had strong anti-noise ability. The square of the linear correlation coefficient of the response of the changes in pH values was 0 . 998 . The curve of the results measured by this system was consistent with that measured by the commercial electrochemical analyzer. The system was built with standard hardware components and the size of the transmitter unit was only 29 mm×14 mm×11 mm. It can be easily used for remote and real-time detection for the potentiometric sensor.

Objective To explore the effects of coincident infection on treatment response and coronary artery lesion (CAL) outcome in children with Kawasaki disease(KD).Methods A retrospective study of 141 children diagnosed on KD between Jul.2005 and Dec.2006 were performed.Standardized clinical assessments,laboratory examinations microbiology test results plus treatment regimens were reviewed.CAL were visualized by using echocardiography.Infectious agents positive (INF+) and negative (INF-) groups were identified,and clinical assessments,laboratory and treatment data were analyzed.Results 1.Concurrent infections:41%(58/141) of children had one of above confirmed infection at KD diagnosis.2.Treatment response:the presence of infection did not alter the response to treatment with intravenous immunoglobulin (IVIG),with resolution of fever within 72 h in 85% (120/141) children after 1 dose of IVIG (2 g/kg) together with aspirin administration regardless of present or absent infection.3.CAL outcome:in total,56.0% (79/141) of children developed CAL at the time of diagnosis,involving dilatation (91.1%,72/79 cases) and aneurysm (8.9%,7/79 cases),and no giant aneurysm was found.Most CAL were recovered within 1 year after treatment.Incidence of aneurysm in INF+ group was significantly higher than that in INF-group (P=0.019).Conclusions Coincident infection would not affect on the clinical assessment,laboratory test results and treatment response to IVIG in children with KD,but would result in higher risk of serious CAL.Therefore,children with infection at diagnosis on KD will not only accept active treatment in acute phase,but also insist on convalescent care and follow-up visit.

The most of secreted proteins are exported by Sec translocase (secretion pathway). SecA ATPase is one of the most important subunit in the Sec translocase, which is preprotein translocase nanomotor that undergo membrane insertion and deinsertion to drive preprotein across the bacterial inner membrane, and SecA is indispensable to bacteria. It should be presumed that the compound which inhibits the activity of SecA ATPase probably can be used as the candidate of bactericide. A secA gene from Pseudomonas aerugi- nosa PAO1 was amplified and expressed in Escherichia coli BL21.19 (secA13). It has been shown that the wild-type SecA of Pseudomonas aeruginosa could fully complement the E. coli amber (secA13) mutant at the non-permissive temperature. So a cell level screening model targeting on SecA was established based on the above result. The inhibition of PaSecA ATPase activity was applied to validate the specificity of the cell-based method. Two positive samples based on both of cell and enzyme activities will be further studied.

To investigate the therapeutic effect of artesunate on mouse cytomegalovirus pneumonia, the BALB/c-nu mice were infected with murine cytomegalovirus-green fluorescent protein (MCMV-GFP) by nose dropping method. The experimental protocol was approved by the Medical Laboratory Animal Ethics Committee of Guangzhou Medical University. The BALB/c-nu mice were randomly divided into five groups: control group, MCMV pneumonia group, and artesunate (60, 120, and 240 mg·kg^-1) groups. The survival rate, weights, and virus loads in lungs among the groups were observed. The degree of histopathologic changes in lungs was assessed directly by hematoxylin-eosin (HE) assay. MCMV-GFP expression was assessed by immunofluorescence. In addition, reverse transcription polymerase chain reaction (RT-PCR) analysis was performed to investigate the content of major immediate early 1 (Mie1) mRNA, and enzyme-linked immunosorbent assay (ELISA) was used to detect the changes of inflammatory factors, interleukin 10 (IL-10), IL-6, and tumor necrosis factor-α (TNF-α). Western blot analysis was used to detect the expression of the changes of nuclear factor-kappa B (NF-κB) signaling pathways in total proteins. Compared with MCMV group, artesunate (120 mg·kg^-1) significantly increased body weights of MCMV-infected nude mice over 30 days, and decreased the viral titer in lung homogenate, lung inflammation, and histological severity. Moreover, the administration of artesunate (120 mg·kg^-1) could downregulate the expression of phospho-NF-κB (p-NF-κB) p65 in the lungs of mice. The present study suggested that artesunate can protect the immunocompromised mice from MCMV-induced interstitial pneumonia via downregulating NF-κB signaling pathway, thus attenuating inflammation in the lungs.
