OBJECTIVE To investigate the efficacy and safety of Wuling capsules combined with low-dose quetiapine in the treatment of oldest-old patients with insomnia accompanied by anxiety and depression. METHODS The clinical data of 96 oldest- old patients （aged≥80 years） with insomnia accompanied by anxiety and depression who were attending outpatient clinics or hospitalized in our hospital from June 2020 to December 2022 were retrospectively analyzed. According to the different drug treatments， the patients were divided into Wuling capsules group （0.99 g， tid， 34 cases）， quetiapine group （25-50 mg， qn， 30 cases） and combination group （using Wuling capsules and quetiapine simultaneously， same as the single drug groups， 32 cases）. Before and after 8 weeks of treatment， the patients of three groups were compared in terms of photoplethysmography sleep monitoring indexes （total sleep duration， sleep efficiency， sleep latency， and the number of awakening）， Pittsburgh sleep quality index （PSQI） score， 14-item Hamilton anxiety scale （HAMA-14） score， 17-item Hamilton depression scale （HAMD-17） score， mini-mental state examination （MMSE） score， and serum levels of interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α）； the therapeutic effects and adverse drug reactions of the three groups were observed and compared. RESULTS Compared with before treatment， the total sleep time， sleep efficiency and MMSE scores of the three groups were significantly longer or higher after treatment （P＜0.05）， while the sleep latency， number of awakening， PSQI score， HAMA-14 score， HAMD-17 score， serum IL-1β and TNF-α levels were significantly shorter or lower after treatment （P＜0.05）. Sleep latency， number of awakening， HAMA-14 score， HAMD-17 score and serum TNF-α level in quetiapine group were significantly shorter or lower than Wuling capsules group after treatment （P＜0.05）. Moreover， the above indexes in the combination group were significantly better than quetiapine group and Wuling capsules group （P＜0.05）. The total effective rate of treatment in the combination 1731786794@qq.com group was significantly higher than the other two groups （P＜0.05）. There was no significant difference in the incidence of mail：2408797210@qq.com adverse drug reactions among the three groups （P＞0.05）. CONCLUSIONS The therapeutic effect of Wuling capsules combined with low-dose quetiapine is better than that of individual drugs for oldest-old patients with insomnia accompanied with anxiety and depression， not increasing the risk of adverse reactions.

Objective:To explore the mechanism of dexmedetomidine (DEX) regulating microglial (MG) polarization and neuroinflammation after traumatic brain injury (TBI) in rats.Methods:Forty-two adult male SD rats were randomly (random number) divided into the sham group, TBI group, TBI+DEX group (further divided into 1 d, 3 d and 7 d subgroups), TBI+NF-κB inhibitor (pyrrolidine dithiocarbamate, PDTC) group and TBI+DEX+PDTC group, with 6 animals in each group. The rat TBI model was established according to the modified Feeney free fall method. PDTC was intraperitoneally injected 1 h after modeling with a dose of 100 mg/kg, and DEX was intraperitoneally injected 2 h after modeling with a dose of 100 μg/kg. Modified neurological severity score (mNSS) was used to evaluate rat neurological function, ELISA was used to detect serum inflammatory factors, and rats’ damaged cortex was collected to detect the phenotype markers of MG and protein expressions of MyD88 and NF-κB p65, and immunofluorescence staining was used to observe the expression and nuclear entry of NF-κB p65 in MG in injured cortex. One-way and two-way ANOVA were used to compare the measurement data among multiple groups.Results:Compared with the sham group, the mNSS score was significantly higher in the TBI group, and DEX treatment significantly decreased the mNSS score of TBI rats ( P<0.05). ELISA and Western blot results showed that in the TBI group, the tumor necrosis factor-α (TNF-α), interleukin (IL)-1β in serum and M1 phenotype marker (TNF-α, IL-1β) in brain were increased, the expression of anti-inflammatory factor IL-10 in serum and M2 phenotype markers (arginase-1 and IL-10) in brain were decreased ( P<0.05), and DEX downregulated the expression of TNF-α, IL-1β in serum and M1 phenotype markers in brain, while upregulated the level of L-10 in serum and the M2 phenotype marker in brain ( P<0.05). In addition, the expression of MyD88 and the nuclear translocation of NF-κB p65 were inhibited in the DEX group, and this effect could be enhanced by PDTC. Conclusions:DEX modulates MG activation in TBI rats by inhibiting NF-κB nuclear translocation and reduces neuroinflammation.

Background: Cardiopulmonary resuscitation (CPR) strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest. During CPR, both healthcare and non-healthcare workers who provide resuscitation are at risk of infection. The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients. Main recommendations: 1) A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs. 2) Psychological counseling and treatment are highly recommended, since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest. 3) Healthcare workers should wear personal protective equipment (PPE). 4) Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19. 5) Hands-only chest compression and mechanical chest compression are recommended. 6) Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early. 7) CPR should be provided for 20-30 min. 8) Various factors should be taken into consideration such as the interests of patients and family members, ethics, transmission risks, and laws and regulations governing infectious disease control. Changes in management: The following changes or modifications to CPR strategy in COVID-19 patients are proposed: 1) Healthcare workers should wear PPE. 2) Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols. 3) Both the benefits to patients and the risk of infection should be considered. 4) Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.

Objective:To investigate the different outcomes of two types of acute kidney injury (AKI) according to standard of Kidney Disease: Improving Global Outcomes-AKI (KDIGO-AKI), and to analyze the risk factors that affect the prognosis of intensive care unit (ICU) patients in China.Methods:A secondary analysis was performed on the database of a previous study conducted by China Critical Care Clinical Trial Group (CCCCTG), which was a multicenter prospective study involving 3 063 patients in 22 tertiary ICUs in 19 provinces and autonomous regions of China. The demographic data, scores reflecting severity of illness, laboratory findings, intervention during ICU stay were extracted. All patients were divided into pure AKI (PAKI) and acute on chronic kidney disease (AoCKD). PAKI was defined as meeting the serum creatinine (SCr) standard of KDIGO-AKI (KDIGO-AKI SCr) and the estimated glomerular filtration rate (eGFR) at baseline was ≥ 60 mL·min -1·1.73 m -2, and AoCKD was defined as meeting the KDIGO-AKI SCr standard and baseline eGFR was 15-59 mL·min -1·1.73 m -2. All-cause mortality in ICU within 28 days was the primary outcome, while the length of ICU stay and renal replacement therapy (RRT) were the secondary outcome. The differences in baseline data and outcomes between the two groups were compared. The cumulative survival rate of ICU within 28 days was analyzed by Kaplan-Meier survival curve, and the risk factors of ICU death within 28 days were screened by Cox multivariate analysis. Results:Of the 3 063 patients, 1 042 were enrolled, 345 with AKI, 697 without AKI. The AKI incidence was 33.11%, while ICU mortality within 28 days of AKI patients was 13.91% (48/345). Compared with PAKI patients ( n = 322), AoCKD patients ( n = 23) were older [years old: 74 (59, 77) vs. 58 (41, 72)] and more critical when entering ICU [acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score: 23 (19, 27) vs. 15 (11, 22)], had worse basic renal function [eGFR (mL·min -1·1.73 m -2): 49 (38, 54) vs. 115 (94, 136)], more basic complications [Charlson comorbidity index (CCI): 3 (2, 4) vs. 0 (0, 1)] and higher SCr during ICU stay [peak SCr for diagnosis of AKI (μmol/L): 412 (280, 515) vs. 176 (124, 340), all P < 0.01]. The mortality and RRT incidence within 28 days in ICU of AoCKD patients were significantly higher than those of PAKI patients [39.13% (9/23) vs. 12.11% (39/322), 26.09% (6/23) vs. 4.04% (13/322), both P < 0.01], while no significant difference was found in the length of ICU stay. Kaplan-Meier survival curve analysis showed that the 28-day cumulative survival rate in ICU in AoCKD patients was significantly lower than PAKI patients (Log-Rank: χ2 = 5.939, P = 0.015). Multivariate Cox regression analysis showed that admission to ICU due to respiratory failure [hazard ratio ( HR) = 4.458, 95% confidence interval (95% CI) was 1.141-17.413, P = 0.032], vasoactive agents treatment in ICU ( HR = 5.181, 95% CI was 2.033-13.199, P = 0.001), and AoCKD ( HR = 5.377, 95% CI was 1.303-22.186, P = 0.020) were independent risk factors for ICU death within 28 days. Conclusion:Further detailed classification (PAKI, AoCKD) based on KDIGO-AKI SCr standard combined with eGFR is related to ICU mortality in critical patients within 28 days.

OBJECTIVE: To observe the effects of a traditional Chinese medicine (TCM) capsule for replenishing qi, nourishing yin and activating blood on Notch/Hes1 signaling pathway in the renal tissue and vascular endothelial CD34 and CD144 expressions in a rat model of diabetic nephropathy. METHODS: Rat models of early-stage diabetic nephropathy were established by left nephrectomy and high- fat and high- sugar feeding combined with intraperitoneal injection of STZ. The rats were randomized into model group, benazepril group, and high-, moderate-, and low-dose TCM capsule groups for corresponding treatments, with 6 normal rats as the control group. After 8 weeks of drug treatment, blood glucose and 24-h urinary albumin of the rats were measured, and the renal histopathology was observed with HE staining; Hes1 expression in the renal tissue was detected with immunohistochemical staining, and the renal expressions of CD34 and CD144 were detected using Western blotting. RESULTS: Compared with the normal control group, the rat models of diabetic nephropathy showed obvious abnormalities in 24- h urinary albumin and expressions of Hes1, CD34 and CD144d. The TCM capsule at both the high and moderate doses significantly reduced 24-h urinary albumin in the rats; the renal expressions of Hes1 and CD34 was significantly reduced in all the dose groups, and the expression of CD144 was significantly reduced in the high- dose group. Compared with benazepril group, the TCM capsule obviously reduced CD34 expression at all the 3 doses and lowered CD144 expression at the low dose. Histopathologically, the rats in the model group showed glomerular hypertrophy, increased mesenteric matrix, thickening and widening of the mesenteric membrane, and nodular hyperplasia. These pathologies were obviously alleviated by treatment with the TCM capsule at the high and moderate doses. CONCLUSIONS The Traditional Chinese medicine (TCM) capsule for replenishing qi, nourishing yin and activating blood can reduce Hes1, CD34 and CD144 in kidney tissue of model rats, play a protective role on kidney function and delay the development of DN.

Objective To evaluate the clinical effects of ultrasound-guided internal jugular vein catheterization in long axis plane,short axis plane and oblique axis plane,in order to identify the opti-mal axis plane for this procedure.Methods One hundred and eighty patients (male 94 cases,female 86 cases,aged 34-82 years)requiring ultrasound-guided internal jugular vein catheterization were in-cluded in this study.They were randomly divided into three groups (n =60 each),long axis group, short axis group and oblique axis group,with 60 cases in each group.The details of catheterization in-cluding the time accessing into vein,the time finishing cannulation,needle redirecting times,number of skin points of puncture,puncture successful rate and complications in the three groups were recor-ded.Results Compared with long axis plane and short axis plane,the oblique axis plane was associat-ed with decreased time for venous access and cannulation.The oblique axis plane also needed less changes of needle direction.The complication of arterial puncture in the oblique axis plane group was significantly lower than long axis plane group and short axis plane group(P <0.05).The number of skin puncture points were similar between the three groups.Conclusion The oblique plane can provide a safe and more effective route to perform the IJV catheterization with minimal risk for carotid artery puncture,which demonstrates the practical superiority over the classic short axis plane and long axis plane for critically ill patients.

Objective To investigate the correlation between plasma soluble CD14 (sCD14)level and disease progression in patients with acute phase of acquired immunodeficiency syndrome (AIDS). Methods Forty-one human immunodeficiency virus (HIV)-infected patients were followed up from June 2007 to June 2010 in Beijing You′an Hospital,including 20 patients with CD4 + T lymphocyte counts more than 350/μL,and 21 less than 350/μL after 3 years of HIV infection.Twenty healthy blood donors were recruited as controls.Enzyme-linked immunosorbent assay (ELISA)was employed to test the plasma sCD14 level of healthy controls and patients infected with HIV at 1 -30 d,31 -90 d,91 - 180 d and 181 -360 d.Student t test was used to compare the means between two groups.ANOVA analysis was used to compare the means among more than two groups.Results The mean plasma sCD14 level in control group was (1 654±904)μg/L.Three years after HIV infection,the sCD14 level of patients with CD4 + T lymphocyte counts less than 350/μL group was (4 214±2 635)μg/L,which was higher than that of patients with CD4 + T lymphocyte counts more than 350/μL ([2 275 ±1 457 ]μg/L).The difference was statistically significant(t=-5 .41 ,P <0.01).The plasma sCD14 level in patients infected with HIV 181 -360 d was significantly higher than that in patients infected with HIV 1 - 30 days ([4 485 ± 2 779]μg/L vs [2 577 ±1 635 ]μg/L;t = -3.39,P <0.05 ).The plasma sCD14 level was positively correlated with HIV viral load (r =0.35,P =0.000 1 ),and negatively correlated with CD4 + T lymphocyte counts (r=-0.28,P =0.001 ).Conclusions The plasma sCD14 level in patients with acute phase of HIV infection is higher than that of healthy people,which increases with prolonged HIV infection.Plasma sCD14 level in of HIV infection acute phase may be closely related to HIV/AIDS progression.

OBJECTIVETo evaluate the influence of sirolimus on the long-term survival of patients after orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC).

METHODSClinic data of 165 consecutive patients who underwent OLT for HCC from February 2005 to March 2012 was analyzed retrospectively. Among them, 94 patients were treated with a sirolimus-based immunosuppressive protocol after OLT, while the other 71 patients with a FK506-based protocol. Postoperative survival time, survival, disease-free survival (DFS) and tumor recurrence rates between the two groups were compared.

RESULTSThe 2 groups were comparable in all clinicopathologic parameters. The sirolimus-based group had higher patient survival rates than the control group at 1-year (87% vs. 97%, P = 0.03), 2-year (80% vs. 88%), 3-year (76% vs. 85%) and 5-year (63% vs. 75%). The 1-year, 2-year, 3-year and 5-year recurrence rates were 12% vs. 3%, 17% vs. 9%, 21% vs. 9% (P = 0.04) and 31% vs. 16% (P = 0.03). Early and mid-HCC (I - II stage) of 131 cases (control group 61 cases, sirolimus-based group of 70 patients). The 1-year, 2-year, 3-year and 5-year survival rates were 90% vs. 97% , 80% vs. 90%, 78% vs. 86% and 65% vs. 82% (P = 0.04) and recurrence rates were 10% vs. 3%, 16% vs. 8%, 18% vs. 8% and 29% vs. 11% (P = 0.01).

CONCLUSIONThe sirolimus-based immunosuppressive protocol reduce long-term postoperative recurrence rate and improve the survival rate of patients after OLT for HCC significantly (especially early-mid HCC).

Objective The purpose of this study was to analyze the relation of blood glucose variability and 28-day mortality in patients with different degree sepsis. Methods From September 1, 2010 to September 30, 2012, all adult patients diagnosed with sepsis and treated at least 3 days in Emergency ICU (EICU) of the first affiliated hospital of Kunming Medical University were enrolled in the study. Then the blood glucose levels and the other requisite clinical data were obtained from historical electronic medical records of patients excluding the patients reached exclusive criteria. The maximum and mean of blood glucose, and the glucose variability (the standard deviation,SD of blood glucose) in each patient were calculated. The patients were assigned according to severity of sepsis, then the relationship between SD of blood glucose and 28-day mortality was statistically assessed. Results There was an important correlation between SD of blood glucose and 28-day mortality (OR=4.237, =0.021) . The glucose variability increased with the serious of sepsis ( = 0.016) . Conclusion Glucose variability is an independent predictor of 28-day mortality in septic patients. In addition, the severity of sepsis has a positive correlation with blood glucose variability.

Objective To evaluate the influence of hepatitis B surface antigen positive or antihepatitis B core positive donors on HBV allograft re-infection or de novo hepatitis B and recipients and grafts survival after liver transplantation.Methods Between June 2004 and December 2011,510 liver transplants were performed at our department while 387 patients were followed up.Among them,9 patients received hepatitis B surface antigen positive grafts,50 patients received anti-hepatitis B core positive grafts,and 328 patients received HBV marks negative grafts.The rate of HBV allograft reinfection or de novo hepatitis B and accumulative recipients as well as grafts survival were compared.Results All recipients with hepatitis B surface antigen positive donors remained hepatitis B surface antigen carriers after operation.HBV allograft re-infection occurred in one recipient of anti-hepatitis B core positive donor group. Five recipients with HBV marks negative donors appeared hepatitis B surface antigen positive,including two cases of Lamivudine resistance leading to HBV allograft reinfection and three cases of de novo hepatitis B from non-related diseases. The 1-,3-,5-year accumulative survival rate in anti-hepatitis B core positive grafts group,hepatitis B surface antigen positive grafts group and HBV marks negative grafts group was 100％,86％,43％; 87％,79％,57％; and 87％,80％,79％,respectively (Log-rank =1.287,P =0.525).And the 1-,3-,5-year accumulative grafts survival rate in these three groups was 100％,86％,43％; 85％,77％,56％;and 86％,79％,77％,respectively (Log rank=1.288,P =0.525).During the follow-up period,no graft loss or death was found to be related to the HBV allograft re-infection or de novo hepatitis B.Conclusion Liver grafts from anti-hepatitis B core positive donors do not increase the risk of graft loss or recipient death due to HBV allograft re-infection or de novo hepatitis B under effective antiviral therapy.Hepatitis B surface antigen positive donors are feasible to save lives or prolong life in emergency situation.
