Objective To investigate the effect of brachial plexus block on stress response in patients who underwent shoulder arthroscopic surgery.Methods A total of 150 patients with shoulder arthritis who underwent shoulder arthroscopic surgery in the Shanghai Fifth People's Hospital,Fudan University from December 2021 to December 2022 were selected as the study subjects.All patients were divided into the control group and the observation group by random number table method,with 75 cases in each group.Patients in the control group were given general anesthesia,while patients in the observation group were given brachial plexus block on the basis of the control group.The mean arterial pressure(MAP),heart rate(HR),norepinephrine(NE),cortisol(Cor)before operation(T0),10 minutes after operation(T1),30 minutes after operation(T2),at the end of operation(T3)and 30 minutes after extubation(T4)of the two groups were compared.The transforming growth factor-β1(TGF-β1),tumor necrosis factor-α(TNF-α),C-reactive protein(CRP)before and 3 days after operation of the two groups were compared.The visual analogue scale(VAS)scores at postoperative wakefulness and 6,12 and 24 hours after operation of the two groups were compared.Results Compared with T0,the levels of MAP and HR at T1,T2,T3,and T4 in the observation group and the control group were obviously decreased(P<0.01),the levels of NE and Cor were obviously increased(P<0.01),while the levels of MAP,HR,NE,and Cor at T1,T2,T3,and T4 in the observation group were obviously lower than those in the control group(P<0.01).The levels of TGF-β1,TNF-α,and CRP 3 days after operation in the observation group and the control group were obviously increased compared with those before operation (P<0. 01), and the above indicators after operation in the observation group were obviously lower than those in the control group (P<0. 01). The VAS scores at postoperative wakefulness and 6, 12 and 24 hours after operation in the observation group were obviously lower than those in the control group (P<0. 01). Conclusion Ultrasound-guided brachial plexus block by interscalene approach can ensure the stability of the vital signs of patients with shoulder arthritis during shoulder arthroscopic surgery, alleviate pain, reduce stress, and reduce inflammatory response.

Objective To analyze the literature related to diphenidol tablets poisoning,the characteristics of poisoning were summarized to provide reference for controlling the suicidal abuse risk of diphenidol tablets.Methods The global literature on suicide,overdose,poisoning,shock,and death related to difenidol published from January 1,2011 to December 31,2022 was analyzed,including gender,age,dosage,cardiac(blood)concentration,poisoning symptoms,etc.Results Young women were the majority of people with poisoning.The highest proportion of the age group is 11 to 30 years group.Patients who take medication doses greater than 3 000 mg may have a higher risk of death;patients with a heart(blood)concentration greater than 6 μg·mL-1 may have a higher risk of death.Malignant arrhythmia,consciousness disorders,coma,and apnea are common serious adverse events during poisoning.Conclusion It is recommended that the drug regulatory authorities should require the Listing permit holder of difenidol tablets to add the risk and symptoms of poisoning into the instructions.It is suggested that restricting individual consumers from purchasing large amounts of difenidol tablets in the short term.It is recommended that canceling the high-dose sales packaging of difenidol tablets.It is suggested that converting difenidol tablets into prescription drugs,even consider canceling the registration certificate of difenidol tablets.

Objective: To investigate the diagnosis and treatment of Chiari malformation patients with hoarseness and other otorhinolaryngological symptoms. Methods: The clinical data of 18 patients of Chiari malformation with hoarseness were retrospectively collected, which was composed of 5 men and 13 women, aged 3-71 with median age of 52. All the patients were admitted to the Affiliated Hospital of Qingdao University from January 1989 to January 2020. All patients underwent brain MRI and laryngoscopy. The patient's symptoms and first diagnosis department, diagnosis time, total course of disease, hoarseness course, diagnosis and treatment, and postoperative recovery time were summarized. Follow-up time was 3-16 years, with median follow-up time of 6.5 years. Descriptive methods were used for analysis. Results: The first visit departments of 18 patients included neurology (9 cases), otorhinolaryngology head and neck surgery (5 cases), pediatrics (2 cases), orthopedics (1 case) and respiratory department (1 case). Except for the 7 cases in neurology department, the other 11 patients were not diagnosed in time. The disease duration of 18 patients with Chiari malformation ranged from 2 months to 5 years, and hoarseness was present from 20 days to 5 years. After diagnosis, 9 patients underwent posterior fossa decompression surgery, and 1 of them underwent syrinx drainage at the same time. The symptoms of 8 cases improved significantly after operation, with the improvement time from 1 to 30 days. In addition, 9 patients chose conservative treatment, among whom 8 had no improvement in symptoms and 6 progressed.

Objective: To summarize the clinical data and prognosis of children with Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL) common genes. Methods: This was a retrospective cohort study.Clinical data of 56 children with Ph-like ALL common gene cases (Ph-like ALL positive group) treated from January 2017 to January 2022 in the First Affiliated Hospital of Zhengzhou University, Henan Children's Hospital, Henan Cancer's Hospital and Henan Provincial People's Hospital were collected, 69 children with other high-risk B cell acute lymphoblastic leukemia (B-ALL) at the same time and the same age were selected as the negative group. The clinical characteristics and prognosis of two groups were analyzed retrospectively. Comparisons between groups were performed using Mann-Whitney U test and χ² test. Kaplan-Meier method was used for survival curve, Log-Rank test was used for univariate analysis, and the Cox regression model was used for multivariate prognosis analysis. Results: Among 56 Ph-like ALL positive patients, there were 30 males and 26 females, and 15 cases were over 10 years old. There were 69 patients in Ph-like ALL negative group. Compared with the negative group, the children in positive group were older (6.4 (4.2, 11.2) vs. 4.7 (2.8, 8.4) years), and hyperleukocytosis (≥50×10⁹/L) was more common (25% (14/56) vs. 9% (6/69)), the differences were statistically significant (both P<0.05). In the Ph-like ALL positive group, 32 cases were positive for IK6 (1 case was co-expressed with IK6 and EBF1-PDGFRB), 24 cases were IK6-negative, of which 9 cases were CRLF2 positive (including 2 cases with P2RY8-CRLF2, 7 cases with CRLF2 high expression), 5 cases were PDGFRB rearrangement, 4 cases were ABL1 rearrangement, 4 cases were JAK2 rearrangement, 1 case was ABL2 rearrangement and 1 case was EPOR rearrangement. The follow-up time of Ph-like ALL positive group was 22 (12, 40) months, and 32 (20, 45) months for negative group. The 3-year overall survival (OS) rate of positive group was significantly lower than the negative group ((72±7) % vs. (86±5) %, χ²=4.59, P<0.05). Compared with the 24 IK6-negative patients, the 3-year event free survival (EFS) rate of 32 IK6 positive patients was higher, the difference was statistically significant ((88±9) % vs. (65±14) %, χ²=5.37, P<0.05). Multivariate Cox regression analysis showed that the bone marrow minimal residual disease (MRD) not turning negative at the end of first induction (HR=4.12, 95%CI 1.13-15.03) independent prognostic risk factor for patient with Ph-like ALL common genes. Conclusions: Children with Ph-like ALL common genes were older than other high-risk B-ALL patients at diagnosis, with high white blood cells and lower survival rate. The bone marrow MRD not turning negative at the end of first induction were independent prognostic risk factor for children with Ph-like ALL common gene.

The Myh3 (myosin heavy chain 3) gene is a marker gene of muscle cell differentiation and regulates the utilization of energy in muscle cells, but whether it affects the glycolysis process of muscle cells in different states is rarely reported. In this paper, the expression patterns of Myh3 and glycolysis-related genes Pkm (M-type pyruvate kinse), Prkag3 (protein kinase adenosine monophosphate-activated γ3-subunit), and Gsk3β (glycogen synthase kinase-3β) were studied by the qRT-PCR (quantitative-Real-Time-PCR) method using C2C12 cells at different stages of myoblast and adipogenic differentiation as models. It was found that in the process of myoblast differentiation of C2C12 cells, the relative expression trends of Myh3 and glycolysis genes Prkag3 and Pkm were basically the same, and the relative expression levels first increased, reached the peak on the second day of differentiation, and then decreased; glycogen synthase the expression trend of the inhibitory gene Gsk3β was relatively stable. In the process of adipogenic differentiation of C2C12 cells, the relative expression trend of Myh3 and glycolysis genes Prkag3 and Pkm remained basically the same, and the relative expression gradually increased, reaching the highest value on the 8th day of differentiation; glycogen synthase inhibitory gene Gsk3β expression remained stable. In the myogenic differentiation state of C2C12 cells, qRT-PCR and Western blotting were used to detect the effects of interfering Myh3 on the mRNA and protein expressions of glycolysis-related genes Pkm, Prkag3, and Gsk3β. The results showed that after interfering with Myh3, the mRNA expressions of glycolysis genes Pkm and Prkag3 were significantly decreased (P<0.01), while the mRNA expression of glycogen synthase inhibitory gene Gsk3β had no significant change (P > 0.05). The protein levels of Myh3 and Pkm were significantly lower than those in the blank group and NC group. Under the adipogenic differentiation state of C2C12 cells, after interfering with Myh3, the mRNA levels of glycogen synthase inhibitor Gsk3β and glycolysis gene Prkag3 were significantly increased (P<0.01), and the mRNA level of glycolysis gene Pkm was decreased; the protein levels of Myh3 and Pkm in the Myh3 interference group were also lower than those in the blank group and NC group. Based on the above studies, there are significant differences in the levels of glycolysis in C2C12 cells in the myogenic and adipogenic states, and the expression patterns of Myh3 and glycolysis genes are similar. Further results showed that Myh3 suppression could inhibit the glycolysis of C2C12 cells in the myogenic state without affecting the glycogen synthesis. Unlike in the myogenic state, interfering expression of Myh3 in the adipogenic state of C2C12 cells inhibited both glycogen synthesis and glycolysis.

Objective: To observe the characteristics and trends during the last 11 years of risk factors of young adults with first acute coronary syndrome (ACS). Methods: It was a cross-sectional study. We included young adults (18 to 44 years old) hospitalized for acute coronary syndrome in Beijing Anzhen Hospital for a first time from January 2007 to December 2017. Acute coronary syndromes include ST-elevation myocardial infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI), and unstable angina (UA). The general information, medical history and laboratory test were recorded. Risk factors of ACS were smoking, dyslipidemia, overweight/obesity, hypertension and diabetes. Results: Data from 7 106 patients were analyzed, mean age was (39.8±4.2) years old and 6 593(92.8%)were men, including 2 254 (31.7%) STEMI, 704 (9.9%) NSTEMI and 4 148 (58.4%) UA. Most patients were male (6 593(92.8%)). Dyslipidemia (85.8%(6 094/7 106)), overweight/obesity (82.3%(5 850/7 106)), and smoking (63.9%(4 545/7 106)) were most prevalent. 98.3% (6 885/7 106) patients had at least 1 risk factor. The prevalence of hypertension, diabetes and overweight/obesity increased from 2007 to 2017. Rates of hypertension increased from 37.1%(111/299) to 48.1%(498/1 035) (P_trend<0.01), diabetes from 12.0%(36/299) to 19.4%(201/1 035) (P_trend<0.01), overweight/obesity from 74.2%(222/299) to 83.9%(868/1 035) (P_trend<0.05), respectively. Conclusions: Dyslipidemia, overweight/obesity and smoking are most prevalent risk factors in young adults with a first ACS and most patients have at least 1 risk factor for ACS. Rates of hypertension, diabetes and overweight/obesity progressively increases over time in this patient cohort.

To establish the ultra performance liquid chromatography (UPLC) fingerprint of Dandeng Tongnao Ruanjiaonang and conduct a systemic, comprehensive quality evaluation of the drug by combining with a chemical pattern recognition method. In this study, Waters UPLC ultra-high performance liquid chromatography instrument and ACQUITY UPLCHSS T3 chromatographic colum n were employed to perform the separation with acetonitrile-0.1% formic acid aqueous solution as the mobile phase for gradient elution; and the detection wavelength was set at 256 nm to establish the UPLC fingerprint of 10 batches of Dandeng Tongnao Ruanjiaonang. Then, the further quality assessment of the drug was carried out by similarity evaluation, Cluster Analysis(CA), Principal Component Analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). Finally, 77 peaks were recognised as common peaks in the fingerprint, and 15 peaks of them were identified using standard references. The similarity value of these 10 batches of drugs was all above 0.960, indicating a relatively stable quality. But minor differences were still discovered between the batches of the drug by CA and PCA. Finally, 6 common peaks were recognised as the quality makers using OPLS-DA method. The analysis method established in this study was scientific, accurate, reliable and simple; fingerprint combined with chemical pattern recognition technique can be used to systematically and comprehensively evaluate the drug quality of Dandeng Tongnao Ruanjiaonang; what's more, it could also provide a reference for the quality control of traditional Chinese medicine and its preparations at the same time.

Objective: To explore the expression and prognostic significance of miR-223 in patients with mantle cell lymphoma (MCL) and to investigate the possible mechanism. Methods: Twenty-one newly diagnosed MCL patients with bone marrow involvement were enrolled in the present study, 20 healthy donors as normal control. The expression level of miR-223 and SOX11 mRNA was determined by RQ-PCR. CCK-8 and flow cytometer assays were used to analyze cell proliferation, cell cycle and apoptosis of the constructed miR-223 overexpressing MCL cell line, Granta519 cells. SOX11 protein expression level was determined by Western blot. The target gene of miR-223 was confirmed by dual luciferase reporter assay. Results: ①Of the 21 newly diagnosed MCL patients, 15 were male and 6 female, the median age was 58 (37-72) years. The expression level of miR-223 was significantly down regulated in MCL patients compared with that of healthy donors (14.7±10.5 vs 1 244.1±1 935.2, P<0.001). The lower expression of miR-223 was inversely correlated with high-risk mantle international prognostic index (P=0.001), elevated LDH (P=0.001), ECOG score ≥2 (P=0.035). ②Using the median relative expression level of miR-223 as the cutoff value, 21 MCL patients were divided into high-expression group (n=10) and low-expression group (n=11) and found that the high-expression group had a significantly superior OS (median OS: 36 vs 12 months, P=0.021). ③In vitro results showed that compared with the control group, the proliferation of miR-223 overexpressed Granta519 cells was inhibited (the most significant reduction on 96h, P<0.001), manifested by lower proportion of cells in G2/M phase (P<0.001) and increased apoptosis (P<0.001), and the expression level of SOX11 protein in Granta519 cells was significantly lower than that of the control group. ④miR-223 could inhibited the 3' untranslated region of SOX11, and the expression level of miR-223 was significantly negatively correlated with mRNA level of SOX11 in MCL patients (r=-0.81, P<0.001). Conclusions: The expression of miR-223 was repressed in MCL and was associated with poor clinical outcomes, which may be probably attributed to its direct targeting SOX11.

BACKGROUNDBispectral index (BIS) is considered very useful to guide anesthesia care in elderly patients, but its use is controversial for the evaluation of the adequacy of analgesia. This study compared the BIS changes in response to loss of consciousness (LOC) and loss of somatic response (LOS) to nociceptive stimuli between elderly and young patients receiving intravenous target-controlled infusion (TCI) of propofol and remifentanil.

METHODSThis study was performed on 52 elderly patients (aged 65-78 years) and 52 young patients (aged 25-58 years), American Society of Anesthesiologists physical status I or II. Anesthesia was induced with propofol administered by TCI. A standardized noxious electrical stimulus (transcutaneous electrical nerve stimulation, [TENS]) was applied (50 Hz, 80 mA, 0.25 ms pulses for 4 s) to the ulnar nerve at increasing remifentanil predicted effective-site concentration (Ce) until patients lost somatic response to TENS. Changes in awake, prestimulus, poststimulus BIS, heart rate, mean arterial pressure, pulse oxygen saturation, predicted plasma concentration, Ce of propofol, and remifentanil at both LOC and LOS clinical points were investigated.

RESULTSBISLOCin elderly group was higher than that in young patient group (65.4 ± 9.7 vs. 57.6 ± 12.3) (t = 21.58, P < 0.0001) after TCI propofol, and the propofol Ce at LOC was 1.6 ± 0.3 μg/ml in elderly patients, which was significantly lower than that in young patients (2.3 ± 0.5 μg/ml) (t = 7.474, P < 0.0001). As nociceptive stimulation induced BIS to increase, the mean of BIS maximum values after TENS was significantly higher than that before TENS in both age groups (t = 8.902 and t = 8.019, P < 0.0001). With increasing Ce of remifentanil until patients lost somatic response to TENS, BISLOSwas the same as the BISLOCin elderly patients (65.6 ± 10.7 vs. 65.4 ± 9.7), and there were no marked differences between elderly and young patient groups in BISawake, BISLOS, and Ce of remifentanil required for LOS.

CONCLUSIONIn elderly patients, BIS can be used as an indicator for hypnotic-analgesic balance and be helpful to guide the optimal administration of propofol and remifentanil individually.

BACKGROUNDThe purpose of this study was to investigate the feasibility of avoiding axillary lymph node dissection (ALND) for patients with only one sentinel lymph node (SLN) metastasis. The characteristics and predictive factors for non-sentinel lymph node (NSLN) metastasis of patients with single positive SLN were also analyzed.

METHODSPatients with no and only one SLN metastasis (0/n and 1/n group, n ≥ 2) were selected from 1228 cases of invasive breast carcinoma, who underwent axillary dissection in Shandong Cancer Hospital between November 1999 and December 2011, to compare the characteristics of NSLN metastasis between them. For the 1/n group, the factors that influenced the NSLN metastasis were analyzed by univariate and multivariate analysis.

RESULTSDifferences of the NSLN metastasis between the 0/n and the 1/n groups were significant (P < 0.001). There was no significant difference between the axillary lymph node metastasis on level III in 1/n group and 0/n group (P = 0.570). When the total SLN number was ≥ 4 and with one positive case, the NSLN metastasis was not significantly different from that in the 0/n group (P = 0.118). In the 1/n group, clinical tumor size (P = 0.012), over-expression of Her-2 (P = 0.003), tumor grade (P = 0.018) and the total number of SLN (P = 0.047) significantly correlated with non-SLN metastasis. Clinical tumor size (P = 0.015) and the expression of Her-2 (P = 0.01) were independent predictive factors for non-SLN metastasis by the Logistic regression model.

CONCLUSIONUnder certain conditions, breast cancer patients with single SLN metastasis could avoid ALND.
