AIM:To compare the recovery of psy-chomotor function after intravenous anesthesia with remazolam or propofol compound alfentanil in patients undergoing painless gastrointestinal en-doscopy.METHODS:78 patients undergoing pain-less gastrointestinal endoscopy were randomly di-vided into group RA and group PA.Remiazolam or propofol combined with alfentanil were given intra-venously in group RA or group PA.The blood pres-sure,heart rate,respiratory rate and saturation of puls oxygen were recorded before procdure(T1),during checking(T2),awaking from anaesthesia(T3)and at discharging from PACU(T4).Psychomo-tor function,as measured by the Trieger's dot test(TDT)and digit symbol substitution test(DSST),were evaluated before anesthesia(T1),at discharg-ing from PACU(T4),1 h(T5)and 2 h(T6)after checking.RESULTS:From assessment of the TDT,number of dots missed(NDM),maximum distance of dots missed(MDDM)and average distance of dots missed(ADDM)at T4,T5 were significantly lower than those at T1 in two groups.The comple-tion rates and accuracy rates of DSST at T4,T5 were significantly lower than those at T1.Results of TDT and DSST at T6 were not significantly differ-ent to those at T1.The results of NDT,MDDM and ADDM at T4,T5 in group RA were significantly low-er than those in group PA.The completion rates and accuracy rates of DSST at T4,T5 in group RA increased significantly compared with group PA.Compared to group PA,the incidence of hypoten-sion was significantly lower in group RA.There was no significant difference in the incidence of respira-tory depression between the two groups.CONCLU-SION:Psychomotor function was fully recovered 2 h after surgery when remazolam compound alfent-anil was used for painless gastrointestinal endosco-py.Compared with propofol,psychomotor function recovery in the remazolam group was faster and there were fewer adverse effects after surgery in group RA.

Cerebral small vessel disease (CSVD) is a senile brain lesion caused by the abnormal structure and function of arterioles, venules and capillaries in the aging brain. The etiology of CSVD is complex, and disease is often asymptomatic in its early stages. However, as CSVD develops, brain disorders may occur, such as stroke, cognitive dysfunction, dyskinesia and mood disorders, and heart, kidney, eye and systemic disorders. As the population continues to age, the burden of CSVD is increasing. Moreover, there is an urgent need for better screening methods and diagnostic markers for CSVD, in addition to preventive and asymptomatic- and mild-stage treatments. Integrative medicine (IM), which combines the holistic concepts and syndrome differentiations of Chinese medicine with modern medical perspectives, has unique advantages for the prevention and treatment of CSVD. In this review, we summarize the biological markers, ultrasound and imaging features, disease-related genes and risk factors relevant to CSVD diagnosis and screening. Furthermore, we discuss IM-based CSVD prevention and treatment strategies to stimulate further research in this field.

Objective: To investigate the predictive value of serum lactate dehydrogenase (LDH) in the prognosis of patients with paraquat (PQ) poisoning, and to provide evidence for early prognosis assessment. Methods: In February 2022, 50 patients with PQ poisoning who completed serum LDH detection admitted to the Department of Emergency Medicine, the First Affiliated Hospital of Wenzhou Medical University from January 2012 to December 2021 were selected as the observation group, and 50 healthy physical examination personnel were randomly selected as the control group. Patients with PQ poisoning were divided into survival group and death group according to the prognosis, and the differences of blood routine routine, liver and kidney function and other indicators in the first admission between the two groups were compared. Multivariate logisitic regression model was established, ROC curve was drawn, and the influencing factors of prognosis of patients with PQ poisoning were analyzed. Results: Compared with the control group, the white blood cell count (WBC), total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), LDH, glucose (GLU) and creatinine (Cr) in observation group were significantly increased, while albumin (ALB) and total cholesterol (TC) were significantly decreased (P<0.05). Univariate analysis showed that WBC, elevated LDH (>247 U/L), TBil, ALT, AST and Cr were significantly different between PQ poisoning survival group and death group (P<0.05). Multivariate logisitic regression analysis showed that elevated serum LDH was an independent risk factor for the prognosis of PQ poisoning patients (OR=9.95, 95%CI: 1.34-73.82, P=0.025). The area under the ROC curve of LDH was 0.811 (95%CI: 0.692-0.930). When the cut-off value was 340 U/L, the sensitivity was 0.889 and the specificity was 0.719. Log-rank test showed that there was a statistically significant difference in survival rate between the normal LDH group and the elevated LDH group (P=0.001) . Conclusion: Serum LDH has a good predictive value in evaluating the prognosis of patients with PQ poisoning. Elevated LDH is a risk factor for poor prognosis of patients with PQ poisoning.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

OBJECTIVE To observe the effect of electroacupuncture(EA)on sleep quality and serum levels of dopamine(DA)and γ-aminobutyric acid(GABA)in patients with chronic insomnia and emotional disorders.METHODS 62 cases of chronic insom-nia with emotional disorders were randomly divided into treatment group and control group,32 cases in each group.Both groups were given sleep education,the treatment group was treated with electroacupuncture,and the control group was treated with blunt non-trans-dermal shallow needling.Both groups were treated for 4 weeks.The Pittsburgh sleep quality index(PSQI),insomnia severity index(ISI),Hamilton Anxiety Scale(HAMA)and Hamilton Depression Scale(HAMD-17)were used to evaluate the sleep quality,insomni-a,anxiety and depression of the two groups before and after treatment.Serum levels of dopamine and γ-aminobutyric acid were meas-ured by ELISA.RESULTS After treatment,the PSQI total score and each factor score of the treatment group decreased(P<0.01,P<0.05),and the ISI,HAMA,HAMD-17 scale scores were significantly lower than those before treatment(P<0.01).Compared with the control group,the scores of each scale in the treatment group were significantly lower(P<0.01).After treatment,the serum levels of DA and GABA in the treatment group were higher than those before treatment and in the control group(P<0.01).CONCLUSION Electroacupuncture is effective in improving the sleep quality of patients with chronic insomnia and emotional disorders,and can re-lieve their anxiety and depression.Its mechanism may be related to promoting the expression of DA,GABA and other transmitters in peripheral blood.

Objective: To investigate the protective effect and mechanism of Nicotinamide Riboside (NR) on lung injury caused by Paraquat intoxicated mice. Methods: Eighty clean male BALB/C mice were selected and averagely divided forty mice into 4 groups with 10 mice in each group, PQ group was given 25% PQ solution (60 mg/kg) by one-time gavage. PQ+NR group were intraperitoneally injected with NR solution (300 mg/kg) 1 hour before given the same amount of PQ solution (60 mg/kg) by one-time gavage, The Control group were given the same amount of saline by one-time gavage, The same amount of NR was intraperitoneally injected before NR group were given saline by one-time gavage. Observed and recorded general condition of PQ intoxicated mice. Observed and recorded the death of mice every half an hour and counted the mortality and drew survival curve of each group after 72 hours exposure. another forty mice were averagely divided and treated by the same way. After 24 hours of modelling, mice were anaesthetized and killed. Then blood was extracted after eyeball was removed. The changes of TNF-a、IL-6 and MPO in serum of mice were detected by ELISA.Two lung tissues were removed from the chest and used to measure the D/W ratio of the lung. The pathological changes of lung were observed and scored under light microscope.The levels of SOD, MDA and Caspase-3 in lung tissues were determined by chemical colorimetry. The expression of Sirt1 and Nrf2 in lung tissues was detected by Western-blot. Results: Compared with the Control group and the NR group, the mice in the PQ group had a poor general condition, such as depression, crouching, skin disorder and reduced activity, food, urine and feces. The symptoms in the PQ+NR group were reduced compared with the PQ group. The survival rate at 72 hours after exposure: 80% in the PQ+NR group and 40% higher than that in the PQ group (P=0.029) . Compared with Control group and NR group, the D/W ratio (0.09±0.07) , lung pathology score under light microscope (11.80±0.37) , TNF-a (39.89±1.48) pg/ml、IL-6 (77.29±2.38) pg/ml、MPO (0.31±0.01) μg/ml、SOD (6.62±0.30) U/mgprot、MDA level (1.21±0.14) mmol/mgprot, Caspase-3 activity (356.00± 27.16) %, Sirt1 and Nrf2 protein expression (1.02±0.14、0.82±0.06) were significantly decreased in PQ group (P=0.004、0.023) ; Compared with PQ group, PQ+NR group significantly increased the D/W ratio (0.10±0.10) , decreased the pulmonary pathology score under light microscope (7.400.51) , decreased TNF-a (33.00± 0.65) pg/ml、IL-6 (52.23±4.23) pg/ml、MPO leve (0.23±0.01) μg/mll, increased SOD leve (9.28±0.45) U/mgprotl, decreased MDA level (0.78±0.02) mmol/mgprot, decreased Caspase-3 activity (222.80±7.59) %, and increased the protein expressions of Sirt1 and Nrf2 (1.62±0.16、1.06±0.04) (P=0.048、0.035) . Conclusion: NR can prolong the survival time of PQ poisoned mice; NR intervention can effectively inhibit the inflammatory response, peroxidation injury and apoptosis of PQ poisoned mice; NR intervention can upregulate the expression of Sirt1 and Nrf2 protein and effectively reduce the lung injury of PQ poisoning.

OBJECTIVE: To compare the clinical efficacy and its effect on serum levels of tumor necrosis factor α(TNF-α), interleukin 1β(IL-1β), interleukin 6 (IL-6) and prostaglandin E₂ (PGE₂) between short needling (close-to-bone needling) and conventional acupuncture for knee osteoarthritis (KOA) with blood stasis obstruction. METHODS: A total of 68 KOA patients with blood stasis obstruction were randomized into a short needling group (34 cases, 3 cases dropped off) and a conventional acupuncture group (34 cases, 3 cases dropped off). The same acupoints (Dubi [ST 35], Neixiyan [EX-LE 4], Binzhong [Extra], Liangqiu [ST 34], etc. on the affected side) were selected in the two groups. In the short needling group, short needling technique was adopted, the needles were slowly inserted and the needle bodies were shaken, thus gradually penetrated to the bone. In the conventional acupuncture group, conventional acupuncture was adopted, the needles were penetrated to the muscle. After qi-arrival, Dubi (ST 35) and Neixiyan (EX-LE 4), Zusanli (ST 36) and Liangqiu (ST 34) were connected with CMNS6-1 electronic acupuncture instrument, with disperse-dense wave, 2 Hz/10 Hz in frequency, the current intensity was based on patients' feeling, the needles were retained for 30 min, at the same time, the knee joint was irradiated for 30 min with a special electromagnetic wave apparatus in the two groups. Once every other day, 3 times a week for 4 weeks. Before and after treatment, the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score, knee joint pain visual analogue scale (VAS) score, inflammatory response related indexes (serum TNF-a, IL-1β, IL-6 and PGE₂) and knee joint ultrasound were observed，and the clinical effect was evaluated in the two groups. RESULTS: After treatment，the pain, stiffness, function scores and total scores of WOMAC were decreased as compared with those before treatment in the two groups (P<0.05), except for the pain score, the changes of above scores in the short needling group were greater than the conventional acupuncture group (P<0.05). After treatment, the VAS scores, serum levels of TNF-a, IL-1β, IL-6, PGE₂ and knee joint synovium thickness, intra-articular effusion were decreased as compared with those before treatment in the two groups (P<0.05), the levels of TNF-a, IL-1β, IL-6 in the short needling group were lower than the conventional acupuncture group (P<0.05). The total effective rate in the short needling group was 87.1% (27/31), which was superior to 83.9% (26/31) in the conventional acupuncture group (P<0.05). CONCLUSION Short needling could improve the knee joint function, relieve the pain and inflammatory response, improve the knee joint synovium inflammatory response, reduce the knee joint intra-articular effusion for KOA patients, its effect is better than conventional acupuncture.

Objective:To evaluate the dose-response relationship of alfentanil inhibiting gag reflex when combined with propofol in elderly patients undergoing painless gastroscopy.Methods:Patients of American Society of Anesthesiologists physical statusⅠor Ⅱ, aged ≥60 yr, scheduled for elective painless gastroscopy, were selected. Propofol 1.5 mg/kg combined with alfentanil was given intravenously in all the patients. The dose of alfentanil was determined by the Dixon up-and-down method. The initial dose of alfentanil was set at 5 μg/kg. The dose of alfentanil in the next patient was determined according to the development of gag reflex, and the ratio between the two successive doses was 1.1. The median effective dose (ED 50) and 95% confidence interval of alfentanil-induced inhibition of gag reflex when combined with propofol in elderly patients undergoing painless gastroscopy were calculated using the by up-and-down sequential allocation. Results:The ED 50 (95% confidence interval) of alfentanil-induced inhibition of gag reflex when combined with propofol 1.5 mg/kg was 2.8 (2.4-3.2) μg/kg in elderly patients undergoing painless gastroscopy. Conclusion:When combined with propofol 1.5 mg/kg, the ED 50 of alfentanil inhibiting gag reflex is 2.8 μg/kg in elderly patients undergoing painless gastroscopy.
