Conclusion The anterior debridement, autograft bone fusion and anterior fixation operation is effective to improve the quality of life, spine function and pain symptom for tuberculosis patients.

Objective To investigate the role of N-myc downstream regulated genes 2 (NDRG2) in attenuation of focal cerebral ischemic-reperfusin injury by sevoflurane preconditioning in rats.Methods Forty-eight healthy male SD rats weighing 280-320 g were randomly divided into 3 groups ( n =16 each):sham operation group (group S),ischemia-reperfusion injury group (group I/R) and sevoflurane preconditioning group (group Sev).Focal cerebral ischemia-reperfusion injury was induced by right middle cerebral artery occlusion (MCAO)for 120 min followed by 24 h reperfusion.In group Sev,2.0％ sevoflurane was inhaled 1 h once a day for 5 consecutive days at 24 h before MCAO.The neurologic function was evaluated at 24 h of reperfusion and than the rats were sacrificed,and the brain was removed for determination of infarct volume percentage,NDRG2 and activated Caspase-3 expression in ischemic penumbra by Western Blot and NDRG2 expression and location by immunohistochemistry.Results The infarct volume percentage,NDRG2 and activated Caspase-3 expression were higher,and neurologic function score was lower in groups I/R and Sev then in group S( P ＜ 0.05).The infarct volume percentage,NDRG2 and activated Caspase-3 expression were lower,and neurologic function score was higher in group Sev then in group I/R ( P ＜ 0.05).The intranuclear NDRG2 positive staining was decreased in group Sev than in group I/R.Conclusion Sevoflurane preconditioning can reduce focal cerebral ischemia-reperfusion injury by inhibiting the expression and activity of NDRG2 and apoptosis in rats.

In order to develop a more effective drug for dry eye disease, the preparation of lifitegrast eye drops was carried out, and the safety and efficacy of lifitegrast eye drops in vitro and in vivo were investigated. First the method for the determination of lifitegrast content was established, and then the composition and preparation process of the preparation were determined by literature review and single factor experiment. Finally, the safety of lifitegrast eye drops was evaluated by Draize eye irritation test and HE staining, and the therapeutic efficacy was evaluated by Schirmer test and ELISA test. The results showed that the final prescription of lifitegrast eye drops consisted of 5% lifitegrast, 0.4% sodium chloride, 0.3%−0.4% anhydrous disodium hydrogen phosphate, 0.3% sodium thiosulfate pentahydrate and 0.3% sodium hydroxide. The appearance of lifitegrast eye drops was transparent and slightly brownish yellow solution, the pH was7.75±0.05, the osmotic pressure was in the range of 200−330 mOsmol/kg and it had good stability at 60℃ for 3 months. There was no significant difference in irritation study compared with normal saline. Schirmer test showed that tear secretion was increased and the expression of inflammatory factors IL-6, IL-1β and TNF-α in tears were significantly decreased after treatment with lifitegrast eye drops and compared to the commercially available emulsion cyclosporine eye drops, it takes effect faster. The above results indicate that lifitegrast eye drops are simple to prepare and stable, which is a better choice for the rapid treatment of dry eye disease.

Objective To evaluate the effect of TanshinonneⅡA preconditioning on nuclear factor kappa B ( NF-κB ) signaling pathway in N9 cells subjected to oxygen-glucose deprivation and restoration ( OGD∕R) . Methods N9 cells cultured in vitro were divided into 4 groups ( n=16 each) by using a ran-dom number table method: control group ( C group) , OGD∕R group, vehicle group ( V group) and Tanshi-none ⅡA preconditioning group ( TP group) . N9 cells were subjected to O2-glucose deprivation for 4 h fol-lowed by restoration of O2-glucose supply for 24 h to establish the OGD∕R model. Group C receive no treat-ment. In group TP, N9 cells were cultured in medium containing Tanshinone ⅡA ( final concentration 5 mg∕L) for 24 h before the model was established. Dimethyl sulfoxide was added to the culture medium in group V. At the 24 h of reoxygenation, the level of lactate dehydrogenase ( LDH) and nitric oxide ( NO) in culture medium was detected by spectrophotometry, cell apoptosis was assessed by using TUNEL, and the expression of NF-κB in nucleus was detected by Western blot. The apoptosis rate was calculated. Results Compared with group C, the levels of LDH, IL-β, TNF-α and NO in culture medium and apoptosis rate were significantly increased, and the expression of NF-κB in nucleus was up-regulated in OGD∕R, V and TP groups ( P<0. 05) . Compared with group OGD∕R, the levels of LDH, IL-β, TNF-αand NO in culture me-dium and apoptosis rate were significantly decreased, and the expression of NF-κB in nucleus was down-reg-ulated in group TP ( P<0. 05) , and no significant change was found in the parameters mentioned above in group V ( P>0. 05 ) . Conclusion The mechanism by which Tanshinonne ⅡA preconditioning reduces OGD∕R injury to N9 cells is related to inhibiting NF-κB signaling pathway.

Objective To analyze the influence of medication compliance of chronic type 2 diabetes management patients on disease control in two communities in Kunming.Methods A total of 138 patients with type 2 diabetes who were included in chronic disease management in Guandu and Xiaobanqiao communities of Kunming were selected from December 2021 to September 2022.Basic information collection and HbAlc and other related tests were improved.A questionnaire survey of 8-item Morisliy medication adherence scale(MMAS-8)was conducted to analyze the levels of HbAlc and other indexes of three groups with high(group A),medium(group B),and low(group C)adherence,and to conduct statistical analysis.Results Group A accounted for 22.5%,group B for 44.9%,and group C for 32.6%.There were significance differences in urinary albumin creatinine ratio(UACR),HbA1c and blood creatinine among the three groups(P<0.05).The levels of UACR,HbAlc and serum creatinine in group A were lower than those in group B and group C,and there was a negative correlation between UACR,HbAlc and serum creatinine and medication compliance rate(P<0.05).Conclusion In the Guandu Community and Xiaobanqiao community of Kunming,only 22.5%of patients with chronic type 2 diabetes had high medication compliance.The higher the compliance,the lower the level of UACR,HbAlc and serum creatinine,there is a correlation between the two,suggesting that medication compliance should be regarded as one of the key points in the management of chronic diabetes mellitus in the community,and the intervention of patients'medication compliance should be strengthened.

Post-traumatic stress disorder(PTSD) caused by various natural disasters and man-made events has gradually become the highlight of neuroscientists. Sleep disorders after PTSD can impair the effect of treatment and affect the patient's prognosis. In addition, treatment for sleep problems can be effective in improving outcomes for people with PTSD, which indicates that it is significant to pay attention to sleep disorders after PTSD. However, current studies have focused more on the incidence of PTSD and severity of related symptoms after a traumatic event, and less on the occurrence and mechanism of sleep disorders after PTSD. A number of articles on stress and sleep disorders published in recent years provide reliable clues to understand the probable mechanisms of sleep disorders after PTSD. After summarizing the latest research results, this article finds that the occurrence of sleep disorder after PTSD may be related to the changes of connectivity between insula, hippocampus and medial-prefrontal cortex. Apart from that, decline in the mean phase difference of slow spindles in PTSD patients may reflect pathological changes in the thalamic cortical circuit, which may contribute to the objective diagnosis of PTSD and the development of sleep-focused interventions. This paper provides a systematic review of changes in sleep characteristics and possible neural circuitry mechanisms after PTSD from clinical and basic perspectives, which may provide potential directions for future researches on the pathological mechanism of sleep disorders after PTSD and screening novel intervention targets.

The lateral hypothalamic area (LHA) plays a pivotal role in regulating consciousness transition, in which orexinergic neurons, GABAergic neurons, and melanin-concentrating hormone neurons are involved. Glutamatergic neurons have a large population in the LHA, but their anesthesia-related effect has not been explored. Here, we found that genetic ablation of LHA glutamatergic neurons shortened the induction time and prolonged the recovery time of isoflurane anesthesia in mice. In contrast, chemogenetic activation of LHA glutamatergic neurons increased the time to anesthesia and decreased the time to recovery. Optogenetic activation of LHA glutamatergic neurons during the maintenance of anesthesia reduced the burst suppression pattern of the electroencephalogram (EEG) and shifted EEG features to an arousal pattern. Photostimulation of LHA glutamatergic projections to the lateral habenula (LHb) also facilitated the emergence from anesthesia and the transition of anesthesia depth to a lighter level. Collectively, LHA glutamatergic neurons and their projections to the LHb regulate anesthetic potency and EEG features.

A growing number of studies have identified sex differences in response to general anesthesia; however, the underlying neural mechanisms are unclear. The medial preoptic area (MPA), an important sexually dimorphic structure and a critical hub for regulating consciousness transition, is enriched with estrogen receptor alpha (ERα), particularly in neuronal clusters that participate in regulating sleep. We found that male mice were more sensitive to sevoflurane. Pharmacological inhibition of ERα in the MPA abolished the sex differences in sevoflurane anesthesia, in particular by extending the induction time and facilitating emergence in males but not in females. Suppression of ERα in vitro inhibited GABAergic and glutamatergic neurons of the MPA in males but not in females. Furthermore, ERα knockdown in GABAergic neurons of the male MPA was sufficient to eliminate sex differences during sevoflurane anesthesia. Collectively, MPA ERα positively regulates the activity of MPA GABAergic neurons in males but not in females, which contributes to the sex difference of mice in sevoflurane anesthesia.

ObjectiveTo investigate the identification of kidney Yang deficiency syndrome of patients with osteoporosis（OP）， and to form the clinical syndrome identification rules of traditional Chinese medicine（TCM）. MethodBasic information， etiology， clinical symptoms and other characteristics of 982 OP patients were included， and statistical tests were used to screen the variables associated with kidney Yang deficiency syndrome. Taking the decision tree as the base model， bootstrap aggregation algorithm（Bagging algorithm） was utilized to establish the classification model of kidney Yang deficiency syndrome in OP， generating numerous rules and removing redundancy. Combining least absolute shrinkage and selection operator（LASSO） regression to screen key rules and integrate them to construct an identification model， achieving the identification of kidney Yang deficiency syndrome in OP patients. ResultEighteen key identification rules were screened out， and of these， where 11 rules with regression coefficients>0 correlated positively with the kidney Yang deficiency syndrome， the rule with the highest coefficient was chilliness（present）&feverish sensation over the palm and sole（absent）. The other 7 rules with regression coefficients<0 correlated negatively with the syndrome， the rule with the lowest coefficient was reddish tongue（present）&diarrhea（absent）&deficiency of endowment（absent）. According to the regression coefficients of each key rule， variables with importance>0.2 were ranked as chilliness， reddish tongue， feverish sensation over the palm and sole， cold limbs， clear urine， diarrhea， deficiency of endowment， prolonged illness. The results of the partial dependence analysis of the identification model showed that compared to OP patients without chilliness， those with chilliness（present） had a 0.266 8 higher probability of being identified as having kidney Yang deficiency syndrome， indicating that this variable had the highest impact on identification of the syndrome. Similarly， compared to OP patients without reddish tongue， those with reddish tongue had a 0.141 9 lower probability of being identified as having kidney Yang deficiency syndrome， indicating that this variable had the highest impact on identifying non-kidney Yang deficiency syndrome. The accuracy， sensitivity， specificity and area under receiver operating characteristic curve（AUC） of the established kidney Yang deficiency syndrome identification model in the test set were 0.865 9， 0.853 7， 0.872 0 and 0.931 5， respectively. ConclusionA precise identification model of OP kidney Yang deficiency syndrome is conducted basing on the rule ensemble method of Bagging combining LASSO regression， and the screened key rules can explain the identification process of kidney Yang deficiency syndrome. In this research， according to the regression coefficients of rules， the importance and partial dependence of variables， combined with the thinking of TCM， the influence of patient characteristics on the identification of syndromes is described， so as to reveal the primary and secondary syndromes of identification and assist the clinical identification of kidney Yang deficiency syndrome.
