The new generation cyclooxygenase (COX-2) inhibitor could reduce the gastrointestinal side effect of NSAID drugs, but eventually increase the cardiovascular risk, because its selective inhibition of COX-2 induces the imbalance between PGI2 and TXA2 and the reduction of vasodilatory NO. Under pathological conditions, active oxygen species (O2-*2, etc) were used to induce endo- thelial dysfunction, activate NF-κB to induce expressions of pro-inflammatory cytokines IL-1β and TNF-α, increase ET-1, TXA2 with vasoconstrictor effect, reduce PGI2 and NO with vasodilatory effect, generate further oxidative damage together with NO, and reduce the bioavailability of NO. NO-NSAIDs and NO-Coxibs drugs raised the level of NO by introducing NO-donor (ONO2). NSAIDs drugs enhanced the anti-inflammatory activity of COX-2 and reduced gastrointestinal side effects by inhibiting selectively COX-2. If antioxidant structures with active ingredients of traditional Chinese medicines were introduced to improve the antioxidant activity of NSAIDs, they could scavenge the active oxygen species to protect the normal function of vascular endothelia and enhance the bioavailability of NO, which is conducive to enhance the cardiovascular safety of cyclooxygenase (COX-2) inhibitor.

Objective:To explore the path and relationship between social support and ruminant meditation of tuberculosis patients on their post-traumatic growth (PTG).Methods:A total of 156 patients treated from January 2018 to August 2019 were selected as the research objects. The social support rating scale, event-related ruminant meditation questionnaire, and post-traumatic growth rating scale were used for investigation and analysis, and 150 valid questionnaires were obtained. The path analysis method was used to analyze the mutual influence between people.Results:The patient ′s post-traumatic growth, social support and ruminant meditation scores were (62.71±12.28), (38.19±9.79) and (27.28±11.18) points, respectively; social support and purposeful ruminant meditation directly affected tuberculosis patient's PTG (effect value was 0.57); social support indirectly positively affected the patient's PTG through purposeful ruminant meditation (indirect value was 0.77), and purposeful ruminant meditation was the mediating variable. Conclusion:The PTG, ruminant contemplation level and social support of pulmonary tuberculosis patients need to be improved. Social support can directly and indirectly affect the PTG level of pulmonary tuberculosis patients.

BACKGROUNDAscorbic acid (AA) represents one of the most important enzyme co-factors, antioxidants and neuromodulators and plays an important role in the cerebral system. Increasing evidence has suggested that AA could treat certain kinds of vertigo diseases such as Meniere's disease. To elucidate the neurochemical functions associated with AA in vertigo, the change of extracellular AA in the brain cortex following caloric vestibular stimulation (CVS) was evaluated.
METHODSAn on-line electrochemical detection was coupled with in vivo microdialysis to continuously monitor the change of extracellular AA in the primary somatosensory (SI) area of guinea pigs following a caloric vestibular stimulation. Sixteen guinea pigs were divided into three groups, i.e., experimental group with irrigation of the ear canal with ice water (0 degrees C) (n = 8), and two control groups, one with irrigation of the ear canal with warm water (38 degrees C) (n = 4) and the other with irrigation of the auricle with ice water (n = 4).
RESULTSIn the experimental group, the ice water irrigation of the left external ear canal induced a horizontal nystagmus towards the right side lasting about 45 seconds. No nystagmus was induced by warm water irrigation of the external ear canal or by ice water irrigation of the auricle. The extracellular AA concentration significantly increased following the ice water vestibular stimulation, reaching a maximum of (130 +/- 20)% (n = 8) of the basal dialysate level (2.61 +/- 0.92) micromol/L (n = 8), lasting at least for an hour. AA level did not change distinctly after the irrigation of the left external ear canal with warm water or the irrigation of the auricle with ice water.
CONCLUSIONSThe concentration of extracellular AA in the brain cortex of the SI area increased following the ice water vestibular stimulation. This demonstration may be useful for the investigation of the neurochemical processes associated with AA in the process of vertigo.

BACKGROUNDTo clarify the features of gene variation among epidemic strains of human rotavirus NSP4 in China.
METHODSSP4 genes from 27 epidemic strains of human rotavirus isolated in different area of China in recent years were amplified with RT-PCR, the resulted cDNAs were cloned and sequenced. The sequences of full length cDNAs were compared with 10 rotavirus NSP4 sequences available in the GenBank using the Clustal x 1.8 TreeView32 and DNA Star softwares. The G serotype of VP7 was analysed by PCR.
RESULTSThe homology of the amino acid among the 27 rotavirus strains isolated in China was 81.7%-99.4%. Based on the variation of amino acid sequence, the virus strains can be divided into two groups, represented by Wa and KUN with the homology of 92.0%-99.4% and 92.0%-98.9% within each group, respectively. The diversity between the two groups were 16.6%-21.0%. The Wa group could further be separated into three subgroups, according to the diversity between those strains and the characterization in the highly variable domain. The association between VP7 serotype and NSP4 genotype was not strong.
CONCLUSIONSThe NSP4 gene of human rotavirus epidemic strains in China can be divided into Wa and KUN two groups, Wa group is the main group and contains three subgroups possessing characteristic amino acid sites. Samples isolated in the same year but not in the same area shared higher homology.
