Objective:To evaluate the efficacy and safety of oliceridine for treatment of moderate to severe pain after surgery with general anesthesia in patients.Methods:The patients with moderate to severe pain (numeric pain rating scale ≥4) after abdominal surgery with general anesthesia from 14 hospitals between July 6, 2021 and November 9, 2021 were included in this study. The patients were assigned to either experiment group or control group using a random number table method. Experiment group received oliceridine, while control group received morphine, and both groups were treated with a loading dose plus patient-controlled analgesia and supplemental doses for 24 h. The primary efficacy endpoint was the drug response rate within 24 h after giving the loading dose. Secondary efficacy endpoints included early (within 1 h after giving the loading dose) drug response rates and use of rescue medication. Safety endpoints encompassed the development of respiratory depression and other adverse reactions during treatment.Results:After randomization, both the full analysis set and safety analysis set comprised 180 cases, with 92 in experiment group and 88 in control group. The per-protocol set included 170 cases, with 86 in experiment group and 84 in control group. There were no statistically significant differences between the two groups in 24-h drug response rates, rescue analgesia rates, respiratory depression, and incidence of other adverse reactions ( P>0.05). The analysis of full analysis set showed that the experiment group had a higher drug response rate at 5-30 min after giving the loading dose compared to control group ( P<0.05). The per-protocol set analysis indicated that experiment group had a higher drug response rate at 5-15 min after giving the loading dose than control group ( P<0.05). Conclusions:When used for treatment of moderate to severe pain after surgery with general anesthesia in patients, oliceridine provides comparable analgesic efficacy to morphine, with a faster onset.

Objective To investigate the efficacy and safety of Chinese herbal compound modified Huanglian Wendan Decoction in the treatment of hypertension complicated with sleep disorders of phlegm-heat harassing the interior type.Methods A total of 70 patients with hypertension complicated with sleep disorders of phlegm-heat harassing the interior type were randomly divided into a control group and an observation group,35 cases in each group.The patients in the control group were treated with conventional western medicine,and the patients in the observation group were treated with modified Huanglian Wendan Decoction on the basis of treatment for the control group.The course of treatment covered four weeks.The Clinical Global Impression(CGI)score,traditional Chinese medicine(TCM)syndrome score,Pittsburgh Sleep Quality Index(PSQI)score,blood pressure,and serum levels of homocysteine(Hey),interleukin 6(IL-6),interleukin 10(IL-10)and interleukin 8(IL-8)levels in the two groups were observed before and after treatment.Moreover,the safety of medication was evaluated in the two groups.Results(1)After four weeks of treatment,the CGI score of the observation group was(1.63±0.60)points,which was significantly lower than that of the control group[(2.74±0.82)points],and the difference was statistically significant(P＜0.01).(2)After treatment,the TCM syndrome score,systolic blood pressure,diastolic blood pressure and PSQI score of the two groups were significantly decreased compared with those before treatment(P＜0.01),and the decrease of TCM syndrome score,systolic blood pressure,diastolic blood pressure and PSQI score in the observation group was significantly superior to that in the control group(P＜0.05 or P＜0.01).(3)After treatment,the levels of serum Hcy,IL-6 and IL-8 in the two groups were significantly decreased compared with those before treatment(P＜0.01),and the serum IL-10 level was significantly increased compared with that before treatment(P＜0.01).The decrease of serum Hcy,IL-6 and IL-8 levels and the increase of serum IL-10 level in the observation group were significantly superior to those in the control group(P＜0.01).(4)During the treatment,no treatment-related adverse reactions or complications occurred in the two groups.Conclusion Modified Huanglian Wendan Decoction has certain efficacy on patients with hypertension complicated with sleep disorders of phlegm-heat harassing the interior type.The decoction can not only reduce the blood pressure and serum Hcy level of the patients,but also regulate the level of inflammatory factors with high safety.

Objective To investigate the effect of intraoperative renal artery resistance index(RI)in predicting postoperative acute kidney injury(AKI)in patients undergoing cardiac surgery with cardiopul-monary bypass(CPB).Methods Forty-four patients undergoing elective cardiac surgery with CPB,21 males and 23 females,aged ≥18 years,BMI 18.5-30.0 kg/m2,ASA physical status Ⅰ-Ⅲ,were select-ed.Left renal artery peak systolic velocity(PSV)and end-diastolic velocity(EDV)were measured by transesophageal echocardiography(TEE)20 minutes after general anesthesia induction(T1)and 30 minutes after CPB cessation(T2).RI was calculated as(PSV-EDV)/PSV.Patients were divided into two groups:the AKI group and the non-AKI group,according to whether occurred AKI by the diagnostic criteria of the kidney disease:improving global outcomes organization(KDIGO).Logistic multivariate regression analysis was performed to identify the risk factors for AKI occurrence.Results Sixteen patients(36％)oc-curred AKI.Compared with the non-AKI group,the CPB duration and aortic cross-clamp duration were sig-nificantly prolonged(P＜0.05),the renal artery RI at T,and T2 were significantly increased in the AKI group(P＜0.05).Multivariate logstic analysis showed that RI at T2 was an independent risk factor for AKI occurrence after cardiac surgery,the AUC was 0.893(95％CI 0.794-0.991,P＜0.010),the sensitivity and specificity were 84.5％and 78.6％,respectively,and the cut-off value was 0.720.Conclusion Intra-operative renal artery RI in patients undergoing cardiac surgery is an independent risk factor for AKI after cardiac surgery,and renal artery RI＞0.720 at 30 minutes after CPB cessation can serve as a predictive in-dicator for AKI after cardiac surgery.

Objective Exploring the effect of Percutaneous angular vertebroplasty(PCVP)on functional recovery in elderly patients with osteoporotic vertebral compression fractures(OVCF).Methods Retrospective selection of clinical data from 108 OVCF patients admitted to our hospital from August 2020 to December 2022.According to the different surgical methods,52 cases were divided into a control group(percutaneous vertebroplasty)and an observation group(percutaneous vertebroplasty)with 56 cases;Compare the recovery of vertebral body function,imaging related parameters,functional impairment and lumbar function,surgical related conditions,gait,and complications between the two groups.Results The intraoperative blood loss in the observation group was less than that in the control group[(10.65±3.52)ml vs.(13.11±3.66)ml,P＜0.05],the number of intraoperative fluoroscopy was less than that of control group[(14.21±4.27)vs.(17.04±4.25),P＜0.05],there was no statistically significant difference in the total clinical effective rate between the observation group of 89.28％and the control group of 86.53％(P＞0.05).After 2 months of surgery,the imaging related parameters,functional impairment,lumbar function,surgical and gait related conditions in the control group were better than those in the control group(P＜0.05).There was no statistically significant difference in the incidence of incision infection,nerve root injury,and recurrent fractures between the two groups(P＞0.05),but the leakage rate of bone cement in the observation group was lower than that in the control group(P＜0.05).Conclusion Both surgeries can effectively improve the level of lumbar vertebral function in OVCF patients.PVCP has advantages in increasing the height of the anterior and posterior edges of the vertebral body,reducing the Cobb angle,and relatively fewer intraoperative fluoroscopy times and bleeding.The incidence of bone cement leakage is lower,making it more safe.

Background: Intrahepatic cholangiocarcinoma (ICC) is a highly desmoplastic tumor with poor prognosis even after curative resection. We investigated the associations between the composition of the ICC stroma and immune cell infiltration and aimed to develop a stromal-immune signature to predict prognosis in surgically treated ICC. Patients and methods: We recruited 359 ICC patients and performed immunohistochemistry to detect α-smooth muscle actin (α-SMA), CD3, CD4, CD8, Foxp3, CD68, and CD66b. Aniline was used to stain collagen deposition. Survival analyses were performed to detect prognostic values of these markers. Recursive partitioning for a discrete-time survival tree was applied to define a stromal-immune signature with distinct prognostic value. We delineated an integrated stromal-immune signature based on immune cell subpopulations and stromal composition to distinguish subgroups with different recurrence-free survival (RFS) and overall survival (OS) time. Results: We defined four major patterns of ICC stroma composition according to the distributions of α-SMA and collagen: dormant (α-SMAlow/collagenhigh), fibrogenic (α-SMAhigh/collagenhigh), inert (α-SMAlow/collagenlow), and fibrolytic (α-SMAhigh/collagenlow). The stroma types were characterized by distinct patterns of infiltration by immune cells. We divided patients into six classes. Class I, characterized by high CD8 expression and dormant stroma, displayed the longest RFS and OS, whereas Class VI, characterized by low CD8 expression and high CD66b expression, displayed the shortest RFS and OS. The integrated stromal-immune signature was consolidated in a validation cohort. Conclusion We developed and validated a stromal-immune signature to predict prognosis in surgically treated ICC. These findings provide new insights into the stromal-immune response to ICC.

OBJECTIVE: To investigate the molecular mechanisms underlying the beneficial effect of electroacupuncture (EA) in experimental models of Alzheimer's disease (AD) in vivo. METHODS: Senescence-accelerated mouse prone 8 (SAMP8) mice were used as AD models and received EA at Yingxiang (LI 20, bilateral) and Yintang (GV 29) points for 20 days. For certain experiments, SAMP8 mice were injected intravenously with human fibrin (2 mg). The Morris water maze test was used to assess cognitive and memory abilities. The changes of tight junctions of blood-brain barrier (BBB) in mice were observed by transmission electron microscope. The expressions of fibrin, amyloid- β (Aβ), and ionized calcium-binding adapter molecule 1 (IBa-1) in mouse hippocampus (CA1/CA3) were detected by reverse transcription-quantitative polymerase chain reaction (qRT-PCR), Western blot or immunohistochemical staining. The expression of fibrin in mouse plasma was detected by enzyme-linked immunosorbent assay. The expressions of tight junction proteins zonula occludens-1 and claudin-5 in hippocampus were detected by qRT-PCR and immunofluorescence staining. Apoptosis of hippocampal neurons was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining. RESULTS: Fibrin was time-dependently deposited in the hippocampus of SAMP8 mice and this was inhibited by EA treatment (P<0.05 or P<0.01). Furthermore, EA treatment suppressed the accumulation of Aβ in the hippocampus of SAMP8 mice (P<0.01), which was reversed by fibrin injection (P<0.05 or P<0.01). EA improved SAMP8 mice cognitive impairment and BBB permeability (P<0.05 or P<0.01). Moreover, EA decreased reactive oxygen species levels and neuroinflammation in the hippocampus of SAMP8 mice, which was reversed by fibrin injection (P<0.05 or P<0.01). Mechanistically, EA inhibited the promoting effect of fibrin on the high mobility group box protein 1 (HMGB1)/toll-like receptor 4 (TLR4) and receptor for advanced glycation end products (RAGE)/nicotinamide adenine dinucleotide phosphate (NADPH) signaling pathways (P<0.01). CONCLUSION EA may potentially improve cognitive impairment in AD via inhibition of fibrin/A β deposition and deactivation of the HMGB1/TLR4 and RAGE/NADPH signaling pathways.

Objective: To explore the impact of health management measures for entry personnel (entry management measures) against COVID-19 on the epidemiological characteristics of imported Dengue fever in Guangdong Province from 2020 to 2022. Methods: Data of imported Dengue fever from January 1, 2016 to August 31, 2022, mosquito density surveillance from 2016 to 2021, and international airline passengers and Dengue fever annual reported cases from 2011 to 2021 in Guangdong were collected. Comparative analysis was conducted to explore changes in the epidemic characteristics of imported Dengue fever before the implementation of entry management measures (from January 1, 2016 to March 20, 2020) and after the implementation (from March 21, 2020 to August 31, 2022). Results: From March 21, 2020, to August 31, 2022, a total of 52 cases of imported Dengue fever cases were reported, with an imported risk intensity of 0.12, which were lower than those before implementation of entry management measures (1 828, 5.29). No significant differences were found in the characteristics of imported cases before and after implementation of entry management measures, including seasonality, sex, age, career, and imported countries (all P>0.05). 59.62% (31/52) of cases were found at the centralized isolation sites and 38.46% (20/52) at the entry ports. However, before implementation of entry management measures, 95.08% (1 738/1 828) of cases were found in hospitals. Among 51 cases who had provided entry dates, 82.35% (42/51) and 98.04% (50/51) of cases were found within seven days and fourteen days after entry, slightly higher than before implementation [(72.69%(362/498) and 97.59% (486/498)]. There was significant difference between the monthly mean values of Aedes mosquito larval density (Bretto index) from 2020 to 2021 and those from 2016 to 2019 (Z=2.83, P=0.005). There is a strong positive correlation between the annual international airline passengers volume in Guangdong from 2011 to 2021 and the annual imported Dengue fever cases (r=0.94, P<0.001), and a positive correlation also existed between the international passenger volume and the annual indigenous Dengue fever cases (r=0.72, P=0.013). Conclusions: In Guangdong, the entry management measures of centralized isolation for fourteen days after entry from abroad had been implemented, and most imported Dengue fever cases were found within fourteen days after entry. The risk of local transmission caused by imported cases has reduced significantly.

Objective: To analyze the safety and efficacy of combined left atrial appendage (LAA) and patent foramen ovale (PFO) closure in adult atrial fibrillation (AF) patients complicating with PFO. Methods: This study is a retrospective and cross-sectional study. Seven patients with AF complicated with PFO diagnosed by transesophageal echocardiography (TEE) in Zhoupu Hospital Affiliated to Shanghai University of Medicine & Health Sciences from June 2017 to October 2020 were selected. Basic data such as age, gender and medical history were collected. The atrial septal defect or PFO occluder and LAA occluder were selected according to the size of PFO, the ostia width and depth of LAA. Four patients underwent left atrial appendage closure(LAAC) and PFO closure at the same time. PFO closure was performed during a one-stop procedure of cryoablation combined with LAAC in 2 patients. One patient underwent PFO closure at 10 weeks after one-stop procedure because of recurrent transient ischemic attack (TIA). All patients continued to take oral anticoagulants. TEE was repeated 8-12 weeks after intervention. In case of device related thrombus(DRT), TEE shall be rechecked 6 months after adjusting anticoagulant and antiplatelet drug treatment. Patients were follow-up at 1, 3, 6, 12, 24 months by telephone call, and the occurrence of cardio-cerebrovascular events was recorded. Results: Among the 7 patients with AF, 2 were male, aged (68.0±9.4) years, and 3 had a history of recurrent cerebral infarction and TIA. Average PFO diameter was (3.5±0.8)mm. Three patients were implanted with Watchman LAA occluder (30, 30, 33 mm) and atrial septal defect occluder (8, 9, 16 mm). 2 patients were implanted with LAmbre LAA occluder (34/38, 18/32 mm) and PFO occluder (PF1825, PF2525). 2 patients were implanted with LACbes LAA occluder (24, 28 mm) and PFO occluder (PF2525, PF1825) respectively. The patients were followed up for 12 (11, 24) months after operation. TEE reexamination showed that the position of LAA occluder and atrial septal defect occluder or PFO occluder was normal in all patients. DRT was detected in 1 patient, and anticoagulant therapy was adjusted in this patient. 6 months later, TEE showed that DRT disappeared. No cardiovascular and cerebrovascular events occurred in all patients with AF during follow-up. Conclusions: In AF patients complicated with PFO, LAAC combined with PFO closure may have good safety and effectiveness.

Objective: To compare the effect of direct surgery or surgery after second-line chemotherapy for colorectal cancer patients with liver metastases who did not achieve objective remission after neoadjuvant chemotherapy. Methods: A retrospective case cohort study was used. The clinical and pathological data of 107 patients with colorectal cancer liver metastases who did not achieve objective response to neoadjuvant chemotherapy at Department of Hepatobiliary Surgery,Cancer Hospital,Chinese Academy of Medical Sciences from December 2008 to December 2016 were retrospectively collected. There were 71 males and 36 females, median age was 57 years (range: 28 to 79 years). According to the different treatment regimens after neoadjuvant chemotherapy,107 cases were divided into a direct surgery group (direct group,n=65) and an operation after receiving second-line chemotherapy group (second-line group,n=42). The propensity score matching(PSM) of the Logistic regression model was used to match the bilobar distribution of liver metastases and the number of first-line chemotherapy cycles in the two groups of patients. The caliper value was set to 0.10 and the matching ratio was 1∶2. T test, Mann-Whitney U test, χ² test or Fisher's exat test was used to analyzed the data between the tuo groups, respectively. Survival analysis design was used to investigate the difference in prognosis between the two groups of patients. Results: The follow-up time(M(IQR)) was 56.3(34.3) months (range: 2.1 to 95.0 months),and all patients were followed up. After PSM,there were 28 cases in the direct group and 42 cases in the second-line group, there were no significant differences in whether R0 resection was feasible,blood loss,blood transfusion,postoperative complications and postoperative hospital stay between the two groups (all P>0.05). The 1,3,and 5-year progression-free survival(PFS) rates of the direct group were 40.0%,16.5%,and 11.0%,and the 1,3,and 5-year overall survival(OS) rates were 98.5%,61.2%,and 41.4%,respectively, the second-line group 1,3,5 years PFS rates were 35.7%,14.3%,14.3%,1,3,5-year OS rate were 95.2%,55.1%,44.4%,respectively. The median PFS time of the direct group and the second-line group was 8.5 months and 7.5 months,respectively,and the difference was not statistically significant (P=0.826). The median OS time of the direct group and the second-line group were 33.8 months and 46.9 months,respectively. The difference was not statistically significant(P=0.646).The median PFS time of the direct group and second-line chemotherapy complete remission and partial remission group(CR/PR group) was 10.2 months and 9.1 months,respectively,and the difference was not statistically significant(P=0.669). The median OS time of the direct group and the second-line CR/PR group was 51.0 months and 46.9 months,respectively,and the difference was not statistically significant(P=0.427). The results of survival analysis suggested that major liver resection was an independent prognosis factor for PFS (HR=1.809,95%CI: 1.067 to 3.067,P=0.028) and OS(HR=2.751,95%CI: 1.317 to 5.747,P=0.007). Second-line chemotherapy was not an independent prognostic factor for PFS (HR=0.945, 95%CI:0.570 to 1.567,P=0.828) and OS (HR=0.866,95%CI: 0.468 to 1.602,P=0.646). Conclusions: There is no significant difference in the short-term outcome and long-term prognosis between direct surgery patients and second-line chemotherapy followed by surgery. Second-line chemotherapy is not an independent prognostic factor for colorectal cancer liver metastases patients who fail to achieve objective response after neoadjuvant chemotherapy.

Thirty-one patients in bundle nursing group and 28 patients in regular nursing group continuously received CRRT for 3 days or more from the first treatment. Before treatment, PT, APTT, and INR of patients in bundle nursing group were 24.10 (16.08, 39.20) s, 38.81 (32.32, 45.50) s, and 1.17 (1.12, 1.19), respectively, similar to 31.75 (22.99, 40.96) s, 41.82 (35.05, 48.06) s, and 1.15 (1.11, 1.19) of patients in regular nursing group (P>0.05); the levels of total calcium and ionic calcium of patients in the two groups were similar (P>0.05). After 3 days of treatment, PT, APTT, and INR of patients in bundle nursing group and regular nursing group were 29.06 (20.11, 39.46) s, 35.25 (30.06, 40.28) s, 1.13 (1.09, 1.17) and 36.51 (26.64, 42.92) s, 39.89 (34.81, 46.62) s, 1.14 (1.10, 1.18), respectively, similar to those before treatment (P>0.05); the level of ionic calcium of patients in regular nursing group was significantly higher than that before treatment (Z=-2.08, P<0.05); the levels of total calcium and ionic calcium of patients in bundle nursing group were both significantly higher than those before treatment (with Z values of -3.55 and -3.69, respectively, P<0.01); compared with those in regular nursing group, APTT of patients was significantly shorter (Z=-2.29, P<0.05), while the total calcium level of patients was significantly higher in bundle nursing group (Z=-2.26, P<0.05). The difference of total calcium between before and after treatment of patients in bundle nursing group was significantly higher than that in regular nursing group (Z=-3.15, P<0.01). The differences of ionic calcium between before and after treatment of patients in the two groups were similar (P>0.05). Before treatment, the level of β₂ microglobulin of patients in bundle nursing group was significantly higher than that in regular nursing group (Z=-2.84, P<0.01), the platelet count of patients in bundle nursing group was significantly lower than that in regular nursing group (Z=-2.44, P<0.05), while the levels of creatinine, urea, cystatin C, mean arterial pressure, pH value, oxygenation index, bicarbonate radical, and lactic acid of patients in the two groups were similar (P>0.05). After 3 days of treatment, the levels of creatinine, urea, β₂ microglobulin, cystatin C, pH value, bicarbonate radical, and lactic acid of patients were all significantly lower than those before treatment (with Z values of -2.10, -2.90, -3.11, -2.02, -2.34, -2.63, and -2.84, respectively, P<0.05 or P<0.01), while the levels of platelet count, oxygenation index, and mean arterial pressure of patients were all significantly higher than those before treatment in bundle nursing group (with Z values of -6.65 and -2.40, respectively, t=-9.97, P<0.05 or P<0.01); the levels of creatinine, urea, β₂ microglobulin, cystatin C, platelet count, pH value, bicarbonate radical, and lactic acid of patients were all significantly lower than those before treatment (with Z values of -5.32, -2.31, -2.41, -2.21, -3.68, -2.93, -2.20, and -2.31, respectively, P<0.05 or P<0.01), while the oxygenation index and mean arterial pressure of patients were both significantly higher than those before treatment in regular nursing group (Z=-5.59, t=-7.74, P<0.01). After 3 days of treatment, compared with those in regular nursing group, the levels of creatinine, cystatin C, platelet count, oxygenation index, bicarbonate radical, and mean arterial pressure of patients were all significantly higher (with Z values of -2.93, -1.99, -6.39, -2.09, and -2.52, respectively, t=-3.28, P<0.05 or P<0.01), while the levels of urea, β₂ microglobulin, pH value, and lactic acid of patients were all significantly lower (with Z values of -3.87, -2.58, -4.24, and -2.75, respectively, P<0.05 or P<0.01) in bundle nursing group. During hospitalization, there were no treatment-related bleeding events or hypernatremia related to citric acid treatment of patients in the two groups. The ratio of total calcium to ionic calcium in one patient in bundle nursing group was >2.5, but there was no manifestation of citric acid accumulation poisoning; 1 patient had hypoionic calcemia, and 1 patient had severe metabolic alkalosis. Five patients had hypoionic calcemia and 2 patients had severe metabolic alkalosis in regular nursing group. Conclusions: The implementation of bundle nursing of citric acid extracorporeal anticoagulation during CRRT for severe burn patients shortens the length of ICU stay, reduces the total cost of treatment in ICU and the occurrence of treatment-related complications, relieves the economic burden of patients, and improves the continuity and quality of treatment.
