OBJECTIVETo explore different frequency electroacupuncture in acupuncture-drug compound anesthesia on analgesic effect and immune function in the pulmonary resection patients in order to recommend the best electroacupuncture frequency in acupuncture-drug compound anesthesia.

METHODSOne hundred and sixty-three patients scheduled for pneumonectomy were randomly divided into group A (n = 31), B (n = 34), C (n = 32), D (n = 34) and E (n = 32). Houxi (SI 3), Zhigou (TE 6), Neiguan (PC 6) and Hegu (LI 4) were selected in the five groups. Group A was treated with sham acupuncture by pasting needles without needle bodies at acupoints and electroacupuncture at the needle handle, and group B with 2 Hz electroacupuncture, and group C with 2 Hz/ 100 Hz electroacupuncture, and group D with 100 Hz electroacupuncture, and group E with 2 Hz/100 Hz transcetaneous acupoints electrical stimulation, and general anesthesia was produced in all the groups followed by 30 min electrical stimulation and the stimulation was lasted till the end of operation. The dosages of the anesthetics and the changes of surface antigen of leukomonocyte (CD3+ , CD4+ , CD8+ and CD4+/CD8+) and natural killer (NK) cell were observed at 1 day before surgery, intraoperative and 1 day after surgery.

RESULTSIn comparison with group A, the dosages of Propofol in group B and D were decreased, Fentanyl in group B, D and E were decreased. CD3+ and CD4+ in 5 groups increased at first and then decreased over time (all P < 0.01), and group E and C could inhibit the decrease of CD3+ and CD4+ in postoperation in comparison with that in the other three groups (all P < 0.05). CD8+ in 5 groups has no change in different times (all P > 0.05), and group E and D could inhibit the decrease of CD8+ in postoperation in comparison with that in the other three groups (all P < 0.05). CD4+/CD8+ in 5 groups has no change in different times (all P > 0.05), and group E and C could inhibit the decrease of CD4+/CD8+ in postoperation in comparison with that in the other three groups (all P < 0.05). NK cells of 5 groups were increased gradually in different times (all P < 0.01), with the similar regulation of NK cells (all P > 0.05).

CONCLUSIONAcupuncture-drug compound anesthesia with 2 Hz and 100 Hz electroacupuncture together with 2 Hz/100 Hz transcetaneous acupoints electrical stimulation have the best analgesic effect, and 2 Hz/100 Hz transcetaneous acupoints electrical stimulation and 2 Hz/100 Hz electroacupuncture have the best regulation of immune function. Acupuncture-drug compound anesthesia with 2 Hz/100 Hz transcetaneous acupoints electrical stimulation is recommended for that it can not only decrease the dosages of the anesthetics, but also significantly improve the immunosuppression in patients undergoing pneumonectomy.

Objective: The accurate measurement of anti-IgE levels in patients′ serum helps for make diagnosis of chronic urticaria (CU). An indirect ELISA method for quantitative detection of IgG anti-IgE, were established. Methods: The serum samples and the clinical data of 75 first-diagnosed CU patients and 120 healthy controls were collected at Shanghai General Hospital during the year of 2018. In the indirect ELISA system to measure the IgG (anti-human IgE), the antigen, Human IgE Myeloma, was coated on the plate; Omalizumab (a humanized anti-human IgE antibody) was the standard, and horse radish peroxidase (HRP)-labeled anti-human IgG was the tracer. The optimum concentrations of serum and HRP-labeled anti-human IgG were determined by chessboard titration, and method evaluation was conducted. The comparison of serum anti-IgE levels in CU patients and healthy people were analyzed by Mann-Whitney U test and chi-square test. Receiver operating characteristic (ROC) curves were applied to establish the diagnostic performance of serum anti-IgE for CU. Results: The coating concentration of IgE was 5.0×10^-4 mg/ml; serum dilution was 1∶300; enzyme-labeled antibody dilution was 1∶100 000. Standard curve was in good linearity with R²=0.996. The intra-and inter-assay coefficient of variation were 3.9%-7.5% and 6.0%-8.2%, and the recovery rate of low and high concentration samples were 95.9% and 108.4%, respectively. When hemoglobin≤1.3 g/L, triglyceride≤4.6 mmol/L, bilirubin≤171 μmol/L, no interference were observed. The limit of blank, limit of detection, and limit of quantitation were 5.8×10^-4, 1.8×10^-3, and 2.0×10^-3 mg/ml. The linearity range was from 2.0×10^-3 to 354.4 mg/ml. No Hook effect was found until anti-IgE reached 354.4 mg/ml. The anti-IgE remained stable after serum storage at 4 ℃ overnight or treated with 6 repeated freeze-thaw cycles. The anti-IgE levels in CU patients [19.0(1.9, 58.6)mg/ml] were significantly higher than those in healthy controls [0.7(0.002, 11.1)mg/ml] with P<0.001. When cut-off value was set as 15.3 mg/ml, in this method, the positive rate of CU patients (54.7%) was significantly higher than these of healthy controls (18.3%) (P<0.001, AUC=0.736). Conclusions The indirect ELISA method for serum anti-IgE measurement was successfully established. Anti-IgE autoantibodies in serum would be used in the diagnosis of CU.

Objective:To explore the method and effect of aesthetic reconstruction of distal segment of finger with modified second toe nail flap while retains the full length of the second toe.Methods:From April 2018 to June 2020, 16 patients with degloving injury of distal segment of fingers were treated. The patients were 11 males and 5 females aged 18 to 45 years in an average of 29 years. All injuries were degloving injury of the distal segment of finger, including 5 index fingers, 7 middle fingers, 3 ring fingers and 1 little finger. The time from injury to operation was 0.5-3.0 hours, with an average of 1.5 hours. The second toe nail flap was used for the reconstruction. After the dorsal flap of the second toe was rotated to the plantar side of the foot, the donor site defect was repaired by a skin graft. The regular follow up reviews were carried out.Results:All 16 flaps survived except 1 flap had necrosis and underwent toe amputation of the distal segment of the second toe. All patients entered follow-up for 4-12 months, with an average of 5.7 months. The blood supply of all flaps was good. After the flaps having atrophied, they were equivalent to the diameter of the body of normal fingers with the TPD at 6.5(4-10) mm; All patients returned to work. According to the Evaluation Standard of Upper Limb Function of Chinese Hand Surgery Society, 13 cases were graded as excellent, 2 were good and 1 was fair.Conclusion:The techniques of modified second toe toenail flap in aesthetic reconstruction of the distal segment of a finger can effectively restore the length and aesthetic appearance of the affected finger, without sacrificing the donor toe. Clinical application of it should be promoted.

Objective: To explore the related factors of negative conversion time (NCT) of nucleic acid in children with COVID-19. Methods: A retrospective cohort study was conducted. A total of 225 children who were diagnosed with COVID-19 and admitted to Changxing Branch of Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from April 3^rd to May 31^st 2022 were enrolled in the study. The infection age, gender, viral load, basic disease, clinical symptoms and information of accompanying caregivers were retrospectively analyzed. According to age, the children were divided into<3 years of age group and 3-<18 years of age group. According to the viral nucleic acid test results, the children were divided into positive accompanying caregiver group and negative accompanying caregiver group. Comparisons between groups were performed using Mann-Whitney U test or Chi-square test. Multivariate Logistic regression analysis was used to analyze the related factors of NCT of nucleic acid in children with COVID-19. Results: Among the 225 patients (120 boys and 105 girls) of age 2.8 (1.3, 6.2) years, 119 children <3 years and 106 children 3-<18 years of age, 19 cases were diagnosed with moderate COVID-19, and the other 206 cases were diagnosed with mild COVID-19. There were 141 patients in the positive accompanying caregiver group and 84 patients in the negative accompanying caregiver group.Patients 3-<18 years of age had a shorter NCT (5 (3, 7) vs.7 (4, 9) d, Z=-4.17, P<0.001) compared with patients <3 years of age. Patients in the negative accompanying caregiver group had a shorter NCT (5 (3, 7) vs.6 (4, 9) d,Z=-2.89,P=0.004) compared with patients in the positive accompanying caregiver group. Multivariate Logistic regression analysis showed that anorexia was associated with NCT of nucleic acid (OR=3.74,95%CI 1.69-8.31, P=0.001). Conclusion: Accompanying caregiver with positive nucleic acid test may prolong NCT of nucleic acid, and decreased appetite may be associated with prolonged NCT of nucleic acid in children with COVID-19.

OBJECTIVE: To explore the effect of intervention adherence on the use of respiratory protective equipment(RPE) among migrant workers who occupationally exposed to organic solvents. METHODS: A total of 901 migrant workers from 60 small and medium-sized enterprises exposed to organic solvents in a district of Guangzhou City were selected as study subjects using three-arm cluster randomized controlled trial. The enterprises were divided into control group, intervention group, and combined intervention group. Migrant workers in the control group did not receive any intervention, while migrant workers in the intervention group received traditional health education and mobile health(mHealth) intervention, and migrant workers in the combined intervention group received interventions of the intervention group plus peer education. The use of RPE by the migrant workers was evaluated in these three groups in the last week, and at the sixth month. RESULTS: The adherence rates of the three mHealth intervention measures(following the WeChat official account of the project, joining the WeChat/QQ group of the project, and reading the provided messages from project team) in the combined intervention group were higher than that in the intervention group(74.8% vs 53.6%, 70.7% vs 41.8%, 78.5% vs 65.0%, all P<0.01). In the two intervention groups, the adherence rates of traditional health education(attending occupational health training, and browsing public welfare posters) were higher than that of mHealth intervention and/or peer education(all P<0.01). Logistic regression analysis showed that regardless of mHealth intervention, traditional health education or peer education, the high compliance subgroups of the two intervention groups were more likely to wear RPE all the time(all P<0.05) compared with the control group. The intervention effectiveness of the combined intervention group was better than that of the intervention group. CONCLUSION: Improving compliance with occupational health education interventions can promote the use of RPE among migrant workers. The implementation of peer education is beneficial to improve intervention compliance and intervention effect of migrant workers.

Objective:To investigate the diagnostic value of independent and combined subtests of the psychometric hepatic encephalopathy score (PHES) in mild hepatic encephalopathy(MHE) of patients with liver cirrhosis, so as to optimize the PHES.Methods:This was a prospective, multicenter and real-world study which was sponsored by the National Clinical Research Center of Infectious Diseases and the Portal Hypertension Consortium. Twenty-six hospitals from 13 provinces, autonomous regions and municipalities countrywide participated in this study, induding Tianjin Third Central Hospital, the Fourth People′s Hospital of Qinghai Province, the Second Affiliated Hospital of Baotou Medical College, the Third People′s Hospital of Taiyuan, the Fifth Medical Center of PLA General Hospital and so on. From October 2021 to February 2022, outpatients and hospitalized patients with liver cirrhosis and no obvious hepatic encephalopathy were consecutively enrolled. All patients received 5 PHES subjects in the same order: number connection test(NCT)-A, NCT-B, digit symbol test(DST), line tracing test(LTT) and serial dotting test(SDT), and the scores were calculated. The total score of PHES <-4 was taken as the cut-off value for diagnosing MHE. Compare the differences in each subtest between MHE group and non-MHE group. Receiver operating characteristic curve(ROC) and area under the curve(AUC) was performed to assess the diagnostic value of independent and combined subtests in MHE. Mann-Whitney U test and DeLong test were used for statistical analysis. Results:A total of 581 patients with liver cirrhosis were enrolled, 457 were diagnosed as MHE, and the incidence of MHE was 78.7%. The results of NCT-A, NCT-B, SDT, LTT, DST of MHE group were 60.00 s(47.01 s, 88.00 s), 90.45 s(69.32 s, 125.35 s), 74.00 s(57.65 s, 96.60 s), 74.72(60.00, 98.61) and 27.00(20.00, 36.00), respectively. Compared those of non-MHE group(34.00 s(29.15 s, 44.48 s), 50.00 s(40.98 s, 60.77 s), 50.00 s(41.07 s, 63.03 s), 46.23(38.55, 59.42) and 42.00(34.00, 50.75)), the differences were statistically significant( Z=12.37, 12.98, 9.83, 11.56, 10.66; all P<0.001). The AUC(95% confidence interval(95% CI)) of subtests of PHES NCT-B, NCT-A, LTT, DST and SDT alone in MHE diagnosis were 0.880(0.849 to 0.910), 0.862(0.828 to 0.896), 0.838(0.799 to 0.877), 0.812(0.772 to 0.851) and 0.788(0.743 to 0.832), respectively. The combination of 2 PHES subtests significantly increased the diagnostic efficacy. Among them the diagnostic efficacy of the combination of NCT-B and LTT was the best, the AUC(95% CI) was 0.924(0.902 to 0.947), the specificity was 91.9% and the sensitivity was 79.2%, which was better than a single PHES subtest (NCT-A, NCT-B, SDT, LTT and DST) and the combination of NCT-A and DST(AUC was 0.879, 95% CI0.847 to 0.910) which was recommended by guidelines on the management of hepatic encephalopathy in cirrhosis, the differences were statistically significant ( Z=3.78, 3.83, 5.57, 5.51, 5.38, 2.93; all P<0.01). Furthermore, compared between the combination of NCT-B and LTT and the combination of 3 subests of PHES, only the diagnostic efficacy of combination of NCT-B, LTT and SDT (AUC was 0.936, 95% CI 0.916 to 0.956) was better than that of the combination of NCT-B and LTT, the difference was statistically significant( Z=2.32, P=0.020). Conclusion:Based on the diagnostic efficacy and clinical feasibility of PHES subtests and their combinations, the combination of NCT-B and LTT is recommended for the diagnosis of MHE.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

This study aimed to investigate the effect and molecular mechanism of sinomenine on proliferation, apoptosis, metastasis, and combination with inhibitors in human hepatocellular carcinoma HepG2 cells and SK-HEP-1 cells. The effect of sinomenine on the growth ability of HepG2 and SK-HEP-1 cells were investigated by CCK-8 assay, colony formation assay, and BeyoClick~(TM) EdU-488 staining. The effect of sinomenine on DNA damage was detected by immunofluorescence assay, and the effect of sinomenine on apoptosis of human hepatocellular carcinoma cells was clarified by Hoechst 33258 staining and CellEvent~(TM) Cystein-3/7Green ReadyProbes~(TM) reagent assay. Cell invasion assay and 3D tumor cell spheroid invasion assay were performed to investigate the effect of sinomenine on the invasion ability of human hepatocellular carcinoma cells in vitro. The effect of sinomenine on the regulation of protein expression related to the protein kinase B(Akt)/mammalian target of rapamycin(mTOR)/signal transducer and activator of transcription 3(STAT3) signaling pathway in HepG2 and SK-HEP-1 cells was examined by Western blot. Molecular docking was used to evaluate the strength of affinity of sinomenine to the target cysteinyl aspartate specific proteinase-3(caspase-3) and STAT3, and combined with CCK-8 assay to detect the changes in cell viability after combination with STAT3 inhibitor JSI-124 in combination with CCK-8 assay. The results showed that sinomenine could significantly reduce the cell viability of human hepatocellular carcinoma cells in a concentration-and time-dependent manner, significantly inhibit the clonogenic ability of human hepatocellular carcinoma cells, and weaken the invasive ability of human hepatocellular carcinoma cells in vitro. In addition, sinomenine could up-regulate the cleaved level of poly ADP-ribose polymerase(PARP), a marker of apoptosis, and down-regulate the protein levels of p-Akt, p-mTOR, and p-STAT3 in human hepatocellular carcinoma cells. Molecular docking results showed that sinomenine had good affinity with the targets caspase-3 and STAT3, and the sensitivity of sinomenine to hepatocellular carcinoma cells was diminished after STAT3 was inhibited. Therefore, sinomenine can inhibit the proliferation and invasion of human hepatocellular carcinoma cells and induce apoptosis, and the mechanism may be attributed to the activation of caspase-3 signaling and inhibition of the Akt/mTOR/STAT3 pathway. This study can provide a new reference for the in-depth research and clinical application of sinomenine and is of great significance to further promote the scientific development and utilization of sinomenine.
