Objective: To investigate the effect of electroacupuncture (EA) on cognitive function in D-galactose (D-gal)-induced aging rats, and the correlation between the effect and nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3)-ASC-Caspase-1 signaling pathway. Methods: Forty-six male Sprague-Dawley (SD) rats were randomly divided into a control group (n=10), a model group (n=12), an EA-7 d group (n=12) and an EA-21 d group (n=12). Except the control group, the other three groups received 42 consecutive days of intraperitoneal injection of D-gal to establish aging rat models with cognitive dysfunction. The control group received the same amount of normal saline via intraperitoneal injection. Two EA groups were given EA therapy for 21 consecutive days (began from the 22nd day of modeling) or 7 consecutive days (began from the 36th day of modeling) accordingly at Dazhui (GV 14), Baihui (GV 20), Shenshu (BL 23) and Zusanli (ST 36). After modeling/ intervention, all four groups received behavioral evaluations by Morris water maze (MWM) test, novel object recognition (NOR) test and step-down passive avoidance (SDPA) test followed by the Western blot (WB) detection of the expression levels of hippocampal NLRP3 inflammasome-associated proteins NLRP3, ASC and Caspase-1. Results: MWM (place navigation test, PNT) results showed that the escape latency in the model group was significantly longer than that in the other three groups (P<0.05), and there was no significant difference among the other three groups on the 1st day of the test (P>0.05). From the 2nd day to the 4th day of the test, there was no significant difference between the EA-21 d group and the control group (P>0.05) in the escape latency; the escape latency was significantly shorter in the EA-21 d group than in the model group and the EA-7 d group (P<0.05). MWM (spatial probe test, SPT) results showed that the time spent in the target quadrant was significantly shorter and platform crossover number was significantly lower in the model group than in the other three groups (P<0.05). The time spent in the target quadrant was longer in the EA-7 d group than in the model group (P<0.05), but was shorter than that in the control group and the EA-21 d group (P<0.05). There was no significant difference in the swimming speed among the four groups (P>0.05). NOR results showed that there was no significant difference in the recognition ratio between the EA-7 d group and the EA-21 d group (P>0.05), and the recognition ratio was significantly higher in the two EA groups than in the model group (P<0.05), but was lower than in the control group (P<0.05). SDPA results showed that the electric shock number was higher in the model group than in the other three groups (P<0.05), and the differences among the other three groups were statistically insignificant (P>0.05). The model group had the shortest step-down latency, followed by the EA-7 d group, the EA-21 d group and the control group in order (P<0.05). The WB results indicated that the expression level of NLRP3 was significantly lower in the control group and the EA-21 d group than in the model group and the EA-7 d group (P<0.05). The expression levels of ASC and Caspase-1 were significantly higher in the model group than in the other three groups (P<0.05), and there was no significant difference among these three groups (P>0.05). Conclusion: NLRP3 inflammasome may be involved in the development of cognitive decline in aging rats; 7 consecutive days of EA intervention can partially improve the cognitive impairment in aging rats though the effect is rather limited; 21 consecutive days of EA intervention may improve the learning and memory abilities in aging rats via downregulating the expression levels of NLRP3 inflammasome-associated proteins in hippocampus.

Objective To evaluate the diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and conventional-transbronchial needle aspiration (C-TBNA) in mediastinal and lung hilar lesions. Method 301 cases of lung hilar and mediastinal lesions were selected from 2010 to 2016. Among them, 183 cases underwent TBNA, and the other 118 cases received EBUS-TBNA technology. During the research, the associations of diagnostic positive rate and complications were analyzed in order to explore the advantage and the value of EBUS-TBNA. Results The positive rates of EBUS-TBNA in central groups (2R, 4L, 4R, 7) were higher than in the peripheral groups (10R, 10L, 11R, 11L) (P < 0.05). When studying the lymph node group 2R, 4R and 7R, the positive rate of EBUS-TBNA is much more significant than conventional TBNA (P < 0.05); When biopsying at the lymph node group R4 and group 7, one needle positive rate of EBUS-TBNA were much more superior than TBNA (P < 0.05), the three needles cumulative positive rate of EBUS-TBNA almost reach the total positive rate(P > 0.05), an approving effect of puncture can be acquired; The accuracy and sensitivity of EBUS-TBNA in the diagnosis of lung hilar and mediastinal lesions were much better than conventional TBNA (P < 0.05), especially the diagnostic positive rate of EBUS-TBNA in benign diseases was higher (P < 0.05); The complications rates in both two technologies were not significantly different (P > 0.05), there were no severe complications during the operations in all cases. Conclusion EBUS-TBNA is useful in diagnosis of mediastinal and hilar lesions of unknown reason, and significant in diagnosis of bronchial and extrabronchial diseases. It is an efficiency and safe operation while further application studies are needed.

Objective To explore the nursing efficacy of handling methods for local tissue damage in-duced by venous fluorouracil exosmosis. Methods 64 cancer patients who were used fluorouracil had 300 venous exosmosis cases,these were divided into two groups randomly with 150 cases in each group.In the exper-imental group, lidocaine plus dexamethasone acetate were used for wet compress for 12～24 hours continuously, then cold dressing for 12～24 hours discontinuously.In the control group, lidocaine plus dexamethasone acetate were used for local block,then cold dressing for 12～24 hours discontinuously. Results The time of local swelling reduction was shorter(P<0.01 ), the condition of subcutaneous hemorrhage was lighter(P<0.05),the recovery time of subcutaneous stasis of blood was shorter (P<0.01) in the experimental group than that in the control group. Conclusions It can reduce patients' pain and local swelling by using lidocaine plus dexam-ethasone acetate for continuouswet compress plus discontinuous cold dressing to treat venous fluorouracil exos-mosis.Patients were willing to accept it and it can avoid the pain and damage induced by local block.

Objective:To investigate the effectiveness and safety of manual acupuncture for memory loss and sleep quality in chronic insomniacs.Methods:A total of 60 eligible participants were enrolled and randomized into either a treatment group or a control group,with 30 cases in each group.The treatment group was intervened by manual acupuncture whereas the control group was given sham acupuncture.In the two groups,the interventions were offered once every other day and three times a week,for 8 weeks in total.Before and after the treatment,Pittsburgh sleep quality index (PSQI) and eventrelated potentials (ERPs) were used to assess the patients' sleep quality and memory,respectively.Meanwhile,adverse events were monitored and recorded.Results:After 8-week treatment,both the treatment group and the control group showed a significant decrease in the PSQI global score (P＜0.001,P＜0.01),and the decrease in the treatment group was more significant than that in the control group (P＜0.001).The intra-group comparisons of ERPs indicated that,the latencies of N1 and P3 were shortened and the amplitudes of N1 and P3 were increased in the treatment group after the intervention,and the differences were statistically significant (P＜0.05,P＜0.001);in the control group,there were no significant changes in the latency and amplitude after the treatment (P＞0.05).The between-group comparisons of ERPs showed that the treatment group was more effective than the control group in shortening the latency of P3 (P＜0.01).Conclusion:Acupuncture can be a safe and effective treatment option for chronic insomnia coupled with memory impairment.

Objective To investigate the effect of nucleocapsid (N) protein of severe acute respiratory syndrome-associated coronavirus (SARS-CoV) on the expression of cyclooxygenase-2 (COX-2). Methods 293T cells were co-transfected with reporter plasmid pCOX-2-Luc containing the luciferase gene under the control of COX-2 promoter and plasmids carrying individual genes of SARS-CoV, and luciferase activity was measured. Expression of COX-2 mRNA and protein was measured by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot. Results N protein of SARS-CoV enhanced COX-2 gene promoter activity, and upregulated COX-2 mRNA expression.COX-2 protein production in 293T cells was N protein concentration-dependent. Conclusion N protein of SARS-CoV could specifically activate COX-2 expression.

Objective:To observe the efficacy and safety of dexzopiclone plus auricular acupressure in intervening primary insomnia.Methods:A total of 72 participants who met the inclusion criteria were enrolled in a randomized controlled trial,with 36 cases allocated to a treatment group and 36 cases allocated to a control group.Both groups were given dexzopiclone as the routine treatment.Patients in the treatment group were given auricular acupressure with Wang Bu Liu Xing (Semen Vaccariae) seeds at the auricular acupoints related to sleep and emotion based on meridian theory,whereas for patients in the control group,the medical plasters with Wang Bu Liu Xing (Semen Vaccariae) seeds were only gently stuck to acupoints unrelated to sleep without stimulation.Patients in both groups were required to visit the hospital once a week for replacing the seeds and plasters.The course of intervention lasted for 8 weeks and the patients were followed up for another 4 weeks.Pittsburgh sleep quality index (PSQI) and Karolinska sleep diary (KSD) were used to evaluate the outcomes.Meanwhile,adverse effects were monitored and recorded.Results:In the enrolled 72 cases,4 patients (one in the treatment group and three in the control group) reported thirst and a bitter taste,and one case in the control group reported nausea and vomiting.At last,3 cases in the control group dropped out for adverse reactions,and 69 cases completed the clinical trial.After 8 weeks of treatment,the global scores of PSQI in both treatment and control groups decreased significantly compared with the baseline (both P＜0.001).Furthermore,the global score of PSQI in the treatment group was lower than that in the control group (P＜0.01).The global scores of PSQI in both groups at the follow-up were significantly different from the baseline (both P＜0.001),but insignificantly different compared with the post-treatment results (both P＞0.05).According to KSD,both treatment protocols could prolong the total sleep time,shorten sleep-onset latency,improve sleep efficacy and sleep quality significantly,and the changes in the treatment group were more significant.The total effective rate was 88.9％ in the treatment group,higher than 81.8％ in the control group,though the difference was statistically insignificant (P＞0.05).Conclusion:Dexzopiclone plus auricular acupressure is effective and safe for patients with primary insomnia both in short and long terms,and it is more effective than monotherapy of dexzopiclone.

To evaluate the regulating effect of Buyang Huanwu decoction and its simple prescription (Naojian tablet) on CDK4/Cyclin D1 expression in hippocampus tissues of rats with cerebral ischemia, SD rats were divided into the sham-operation group, the model group, the Buyang Huanwu decoction group (ig, 3.15 g · kg⁻¹) and the simple prescription group (ig, 2.41 g · kg⁻¹). Each group was further divided into five subgroups based on time points after the administration, i. e. 1 d, 3 d, 7 d, 14 d and 28 d, respectively. CDK4/Cyclin D1 expressions of the group at different time points were examined by using immunohistochemistry and real-time qPCR. According to the results, the cerebral ischemia model group showed higher CDK4/Cyclin D1 expression than the sham-operation groups (P < 0.05), suggesting that the cell cycle signal pathway would be activated by the cerebral ischemic injury. Both Buyang Huanwu decoction and simple prescription groups showed significantly lower cyclin expression than the model group at 3 d, 7 d, 14 d, 28 d (P < 0.05), indicating both Buyang Huanwu decoction and its simple prescription could play the neuroprotective effect through the cell cycle signal pathway.
