ObjectiveTo further understand the clinic manifestations of childhood primary Sjogren's Syndrome(pSS) and enhance early diagnosis. MethodsFive cases of pSS from Renji Hospital, Shanghai, were reported and their clinical features were analysoed. And literatures from Medline database and Weipu database were reviewed and discussed. Results①Childhood pSS had various clinic presentations that were non-specific and sicca symptoms were absent or occur late in most cases. ② The most common presentations were recurrent parotiditis and cutaneous manifestations with various locations and forms. ③ American-European Criteria for SS were not suitable for the diagnosis of childhood pSS. ConclusionRecurrent parotiditis and cutaneous manifestations in children can be used as clues for the diagnosis of childhood pSS but needs to be further confirmed by the positive results of salivary gland biopsy and autoantibodies examination, particularly SSA/SSB.

Objective To investigate the effects of hyperbaric Oxygen (HBO)exposure on Caspase-3 and Bcl-2 mRNA ex-pressions in both internal carotid artery (ICA)and basal artery (BA)in rabbits.Methods Twenty-four healthy adult New Zealand rabbits were randomly divided into 2 groups:HBO group and the control group,with each group consisted of 12 animals.The rab-bits in the HBO group were exposed to HBO at 2.2 ATA for 60 minutes each day for 3 successive days.The rabbits in the control group were normally fed without any treatment.Real-time PCR was used to detect Caspase-3 and Bcl-2 mRNA expressions in both ICA and BA in 2 groups.Results HBO significantly decreased the Caspase-3 mRNA expression [(0.038 ±0.006 )vs .(1.000 ± 0.225)]and increased the Bcl-2 mRNA expression [(1.877 ±0.1 69)vs .(1.000 ±0.364)].In ICA,HBO similarly decreased the Caspase-3 mRNA expression [(0.41 9±0.091)vs .(1.000 ±0.1 75)]and increased the Bcl-2 mRNA expression [(1.269 ±0.270) vs .(1.000±0.1 1 7)]in BA.All the differences mentioned above were of statistical significance (P <0.01).Conclusion HBO ex-erts an inhibition effect on apoptosis in cerebral vascular endothelial cells.The mechanism may be related to inhibiting the expres-sion of Caspase-3 mRNA and promoting the expression of Bcl-2 mRNA.

OBJECTIVE:To establish a method for the contents determination of 9 components in Guizhi decoction,and com-pare the effects of traditional decoction method and the extracting machine decoction method on these contents in Guizhi decoction. METHODS:HPLC was performed on the column of Agilent Zorbax SB-C18 with mobile phaseof acetonitrile- 0.1% phosphoric ac-id(gradient elution)at a flow rate of 1.0 ml/min,the detection wavelength was 230 nm,254 nm and 280 nm,the column tempera-ture was 25℃,and the injection volume was 10μl. RESULTS:The linear range was 0.410 2-210.0μg/ml for gallic acid(r=0.999 9), 0.994 0-254.5μg/ml for albiflorin(r=0.999 9),1.636 0-1 675.0μg/ml for paeoniflorin(r=0.999 9),0.988 3-506.0μg/ml for liquiri-tin(r=0.999 6),0.987 3-31.59 μg/ml for coumarin(r=0.999 5),0.486 8-124.6 μg/ml for cinnamic acid(r=0.999 5),2.458 0-314.6μg/ml for cinnamaldehyde(r=0.999 5),0.034 3-1.096 μg/ml for 2-methoxy cinnamaldehyde(r=0.999 8),and 1.711 0-219.0 μg/ml for glycyrrdhizic acid (r=0.999 7);RSDs of precision,stability and reproducibility tests were lower than 5%,recoveries were 93.56%-103.19%(RSD=4.00%,n=9)、101.51%-107.32%(RSD=2.21%,n=9)、95.08%-103.76%(RSD=2.87%,n=9)、100.82%-105.73%(RSD=1.85%,n=9)、85.08%-89.12%(RSD=1.40%,n=9)、92.31%-99.12%(RSD=2.71%,n=9)、99.17%-102.32%(RSD=1.24%,n=9)、100.15%-103.98%(RSD=1.18%,n=9)、99.93%-102.61%(RSD=1.03%,n=9). The content of total effective components from the extracting machine decoction method was 4 565μg/g,that from the traditional decoc-tion method was 2 742 μg/g.CONCLUSIONS:The method is simple,stable and reproducible,and can be used for the simultaneous determination of 9 componentsin Guizhi decoction. The contents of gallic acid,albiflorin and 2-methoxy cinnamaldehyde are first re-ported. The total effective components from the extracting machine decoction method are higher than that from the traditional decoc-tion method.

ObjectiveTo observe the effect of cognitive therapy and acupuncture on insomnia. Methods72 insomnia sufferers were divided into two groups averagely. 36 sufferers were treated with cognitive therapy and acupuncture (treatment group), and other 36 sufferers were treated with acupuncture (control group) only.ResultsA month after treatment, ,15 sufferers were cured, 18 sufferers were obviously improved, 2 sufferers were improved and one did not show any improvement in the treatment group.Otherwise, 6 sufferers were cured, 12 sufferers were obviously improved, 12 sufferers were improved and 6 did not show any improvement in the control group. (P<0.05)ConclusionCognitive therapy and acupuncture used together shows more efficacy on insomnia compared with acupuncture alone.

Objective:
To investigate the clinical value of the serum new molecular markers, soluble triggering receptor expressed on myeloid cells-1(sTREM-1)and soluble hemoglobin scavenger receptor(sCD163), in the diagnosis of sepsis in elderly patients with burns.
Methods:
A total of 58 inpatients with burns from Jun 2017 to June 2018 were enrolled in the study.Patients were divided into three groups: the sepsis group(n=12), the localized infection group(n=21)and the non-infection group(n=29). The levels of sTREM-1 and sCD163 were determined by enzyme-linked immunosorbent assays(ELISAs). The clinical diagnostic value of sTREM-1 and sCD163 was assessed by receiver operating characteristic(ROC)curve analysis.
Results:
There was a statistically significant difference in the levels of sTREM-1 and sCD163 at day 1 between the three groups(

Extracellular vesicles are a kind of membrane structures deriving from cells, which exist widely in urine, blood, saliva, milk, cerebrospinal fluid, amniotic fluid and other body fluid.Extracellular vesicles contain nucleic acid, enzymes, proteins and other bioactive molecules, which can convey the biological information to target cells through a variety of modes and participate in the pathophysiological processes of target cells.In recent years, it is considered that extracellular vesicles are associated with the pathogenesis of inflammatory disease of pulmonary such as asthma, chronic obstructive pulmonary disease and acute lung injury/acute respiratory distress syndrome, and have potential therapeutic value through a large body of research.
