Meta-analysis results of RCT showed there was no statistically significant difference between the two groups in reducing low-density lipoprotein cholesterol (LDL-C)levels [MD = - 0.05,95% CI(- 0.12,0.02),P=0.16] and increasing Δ 基金项目:国家重点研发计划项目(No.2017YFC0910004);山 东省重点研发计划项目(No.2020RKB14165) high-density lipoprotein cholesterol (HDL-C)levels [MD = *硕士研究生 。研究方向:临床药学。E-mail:1677032023@qq. - 0.00,95% CI(- 0.02,0.01),P=0.52];the degree of com reducing total cholesterol (TC)level [MD =-0.11,95%CI # 通信作者:主任药师,硕士生导师。研究方向:临床药学、药事 ( - 0.17,- 0.06),P<0.000 1] and triglyceride (TG) 管理。电话:0351-89268349。E-mail:13791120711@126.com level [MD =-0.05,95%CI(-0.09, -0.01),P=0.02] in ·358· China Pharmacy 2022Vol. 33 No. 3 中国药房 2022年第33卷第3期 generic drug group was lower than orig inal drug group ,with statistical significance difference. There was no statistical significance difference in total incidence of adverse drug reaction (ADR)[OR=1.08,95% CI(0.85,1.37),P=0.55] and the incidence of other ADR(P>0.05). The results of subgroup analysis showed that the reductions of TC and TG of generic drugs produced by Beijing Jialin Pharmaceutical Enterprise (hereinafter refer to Jialin generic drugs )were less than those of the original drug ,and the difference was statistically significant ;compared with original drugs ,there was no significant difference in other indexes or all indexes of the generic drugs from other manufacturers. Compared with original drugs ,the reductions of TC and TG in 20 mg/d group of Jialin generic drugs were less than original drug group ;the degree of TC reduction at 12 and 24 weeks of follow-up and TG reduction at 24 weeks of follow-up were less than those of the original drugs ,the difference was statistically significant ;there was no significant difference in other indexes. The qualitative description of RCS showed that for elderly patients with death/acute coronary syndrome ,there was no statistical difference between the two groups in terms of cardiovascular events or serious side effects. For the adult patients who switched from original drugs to generic drugs ,the effect of generic drugs instead of original drugs would not be reduced ,but the increase of HDL-C was less than that of original drug. CONCLUSIONS In terms of effectiveness,generic drugs of atorvastatin can replace original drugs and caution should be taken on the levels of HDL-C ,TC and TG for long time use ;in terms of safety ,generic drugs are similar to the original drugs.

ABSTRACT

@#Objective    To investigate the diagnostic value and safety of electromagnetic navigation bronchoscopy combined with radial endobronchial ultrasound in peripheral pulmonary nodules. Methods    The clinical imaging, surgical and pathological data of 60 patients with 76 peripheral pulmonary nodules who underwent electromagnetic navigation bronchoscopy combined with radial endobronchial ultrasound guided biopsy in the Nanjing Drum Tower Hospital, The Affiliated Hospital of Nanjing University Medical School from June 2020 to June 2021 were retrospectively analyzed. The diagnosis rate and complications were analyzed and summarized. The 76 pulmonary nodules were divided into a small pulmonary nodules group (10 nodules, diameter≤1 cm) and a pulmonary nodules group (1 cm<diameter≤3 cm, 66 nodules) according to diameter. The two groups were compared in terms of operation and diagnosis rate. Results    Pulmonary nodules diameter was 1.8±0.6 cm, operation time 29.8±8.6 min, navigation 2.9±0.9 times, biopsy 9.5±1.9 pieces. In the 76 pulmonary nodules, 55 were confirmed by pathology, with a total diagnosis rate of 72.4%,  including 32 of malignant lesions and 23 of benign lesions. In the 76 pulmonary nodules, 59 had grade 0 hemorrhage, 17 had grade 1 hemorrhage, and none had grade 2 or more serious hemorrhage. Eight patients developed pneumothorax after surgery, and the degree of lung compression was less than 30%, which was improved after symptomatic treatment with oxygen inhalation. The operation time in the small pulmonary nodules group was significantly longer than that in the pulmonary nodules group, and there was no significant difference in diagnosis rate or complications between the two groups. Conclusion    Electromagnetic navigation bronchoscopy combined with radial endobronchial ultrasound is a safe and effective method for the diagnosis of periphery pulmonary nodules, and it also has a high diagnostic rate for small pulmonary nodules (≤1 cm), which is worthy of clinical promotion and application.

ABSTRACT

OBJECTIVE To study the neuroprotective effects of Shenzao jianna o oral liquid (SZJN)on Alzheimer ’s disease (AD)model mice and its mechanism. METHODS The mice were randomly divided into sham operation group ,model group , Donepezil hydrochloride tablet group (0.65 mg/kg),SZJN low-dose ,medium-dose and high-dose groups (0.3,1.5 and 7.5 g/kg, calculated by crude drug quantity ),with 12 mice in each group ,half male and half female. Each group was given relevant medicine(intragastric administration of water at constant volume in sham operation group and model group ),twice a day ,for consecutive 28 d. On the 15th day of administration ,intracerebroventricular injection of β-amyloid 1-42(Aβ1-42)combined with intraperitoneal injection of scopolamine hydrobromide were used to induce AD model. Morris water maze was used to detect the learning and memory ability of mice. HE staining and Nissl staining were used to evaluate the pathological changes of brain tissue in mice. The levels of MDA and SOD in brain tissue of mice were detected. The phosphorylation level of cyclic adenosine monophosphate response element binding protein (CREB) and expression of brain-derived neurotrophic factor (BDNF) in hippocampal tissues were detected by Western blot. RESULTS Compared with sham operation group ,the escape latency of the model group was significantly prolonged ,and the number of crossing the platform and the percentage of residence time in the target quadrant were significantly reduced (P<0.01). The level of SOD in brain tissue ,the phosphorylation level of CREB and the expression level of BDNF in hippocampus decreased significantly (P<0.01),while the level of MDA increased significantly (P< 0.01). In hippocampal CA 1 area and cortical tissue ,nerve cells showed significantly decreased number ,the disordered arrangement and large gap ;the shape of nucleus was irregular and deeply stained ,and Nissl body was blurred ,loosely arranged and the number decreased. Compared with model group ,the escape latency of mice in each dose group of SZJN was significantly shortened ,and the times of crossing the platform and the percentage of residence time in the target quadrant were significantly jing- increased(P<0.01). Above indexes of brain tissue in mice were reversed sig nificantly in SZJN high-dose group (P<0.01),and pathological damage of brain tiss ue was improved. CONCLUSIONS SZJN can significantly improve the learning and memory ability of AD model mice ,and alleviate the pathological injury and oxidative stress of brain tissue ,which may be related to the activation of CREB/BDNF signaling pathway.

ABSTRACT

Low ionizability and poor chemical instability make some target analytes not suitable for direct LC-MS/MS analysis. To improve the detection performance, chemical derivation is frequently imported. However, such technology involves multiple disciplines such as laboratory medicine, organic chemistry and separation science. At present, it′s still a challenge for general application of chemical derivatization in routine clinical laboratories in our country. This article summarizes the key scientific connotation of chemical derivatization in the detection of vitamins, steroids, neurotransmitters and therapeutic drugs, and describes the derivatization approaches for development of chemical mass spectrometry in the future.

ABSTRACT

Objective:To observe the effect of adipose tissue decellularized matrix hydrogel (DAT-gel) on the repair of sciatic nerve defect in rats.Methods:From April, 2019 to April, 2020, aseptic granular adipose tissue was collected from healthy adult women who underwent thigh or abdominal liposuction in the Department of Plastic Surgery, the First Medical Centre of the PLA General Hospital. Decellularisation and enzymatic digestion of adipose tissue were performed to prepare DAT-gel. Scanning electron microscope (SEM) was used to observe the ultrastructure of the hydrogel, and rheology was employed to test the gel dynamics and viscoelasticity of the hydrogel. A rat model of sciatic nerve defect was established and randomly divided into 3 groups: simple chitin catheter group (Chitin group), DAT-gel plus chitin catheter group (DAT-gel group) and autologous nerve reverse connection group (Autograft group) with 10 rats in each group. At the 12th week after surgery, the general view, function and morphology of the regenerated nerve were observed to evaluate the repairing status of the injured nerve. One-way analysis of variance (one-way ANOVA) was used for data analysis. If the difference between the groups was statistically significant, the Turkey method was further used for pairwise comparison. P<0.05 was considered as statistically significant. Results:The results of SEM showed that the DAT-gel had a three-dimensional structure in porous fibre network. The results of rheological test results showed that the complex viscosity of the hydrogel at 4 ℃ and 37 ℃ were 148.91 mPa·s and 801.29 mPa·s, respectively. DAT-gel underwent a sol-gel phase transition when the temperature had been increased. The results showed that DAT-gel had a good temperature-sensitive effect, and its critical point of sol-gel phase transition was similar to the internal temperature of rat. The results of animal experiments showed that the morphology and function of the regenerated nerve in the DAT-gel group were superior to Chitin group at 12 weeks after surgery, according to macroscopic view of the regenerated nerve, electrophysiology of the nerve, the morphology of the new axon and the target muscle, etc.. There was statistically significant between groups ( P<0.05). Conclusion:DAT-gel can significantly promote a repair of sciatic nerve defects in rats.

ABSTRACT

Objective:To investigate the status quo of continuing education and training needs among general practitioners in Pudong New Area of Shanghai.Methods:An online questionnaire survey was conducted among general practitioners registered in the community health service center of Shanghai Pudong New Area in September 2019. The questionnaire included items of general information, the status quo of continuing education, the training needs and demands, and the knowledge and skills to be improved.Results:There were total 1 824 general practitioner in Pudong New Areal, 861 participated in the survey with a participant rate of 47.2%. A total of 861 valid questionnaires retrieved with a response rate of 100.0%. Among all participants, 79 (9.18%) thought that continuing education was very useful for improving or developing their professional ability, 564 (65.51%) thought it was useful, and 41 people (4.76%) thought it was almost useless. There were significant different in views on the roles of continuing education among participants with different ages, types of registration, and working years (χ2=15.544, 15.382, 21.979; P<0.05). There are 112 participants (13.01%) who spend less than 1 day in continuing education each month, and 224 (26.02%) who spent more than 3 days a month in continuing education, the times of attending continuing education was related to the taking administrative duty for general practitioners (χ2=9.551, P<0.05). When general practitioners choose continuing education programs, the first consideration was the practicability of the contents [772 (31.94%)], followed by the form of teaching [541 (22.38%)]. The three most recognized forms of continuing education courses were online learning (28.22%), training and off-line teaching (25.58%) and special lectures (24.69%) The three most required knowledge and skills to be improved through continuing education were the endocrine system, respiratory system, and blood circulation system. Conclusions:The survey shows the current status and traing needs of continuing education among general practitioners in Shanghai Pudong New Area, which indicates that it is necessary to take the job competence as the core and carry out various activities of continuing education for general practitioners in community health service centers.

ABSTRACT

Objective:To investigate the value of flow cytometric analysis of peripheral blood in the diagnosis of erythroderma.Methods:A total of 29 patients with erythroderma were collected from Hospital of Dermatology, Chinese Academy of Medical Sciences from September 2017 to December 2020, including 6 with erythrodermic mycosis fungoides (EMF) , 5 with Sézary syndrome (SS) , 18 with inflammatory erythroderma (IE) with different etiologies. Four healthy volunteers served as healthy controls. Flow cytometry was performed to detect peripheral blood lymphocyte subsets, immunophenotypes and clonality, and their differences were analyzed between inflammatory erythroderma and lymphoma-related erythroderma. One-way analysis of variance and least significant difference- t test were used for comparisons between groups. Results:The proportions of T cells, B cells, NK cells and CD4 -CD8 - cells significantly differed among the EMF group, SS group, IE group and control group (all P < 0.001) . The proportion of T cells was significantly higher in the SS group (93.8% ± 3.4%) than in the EMF group (42.7% ± 6.4%) and IE group (46.0% ± 6.8%, t = 12.8, 14.4, respectively, both P < 0.001) , and the proportion of CD4 -CD8 - cells was significantly lower in the IE group (0.37% ± 0.40%) than in the EMF group (2.93% ± 0.84%) and SS group (2.38% ± 0.74%, t = 9.2, 6.7, respectively, both P < 0.05) . The expression of clonal T-cell receptor β-chain variable region (TCR-vβ) was not detected in healthy controls or IE patients; the T cell subsets expressing clonal TCR-vβ were detected in 3 cases of EMF and all cases of SS, and they were all identified to be cells with a CD4 +CD7 -CD26 - phenotype. There were significant differences among the above 4 groups of subjects in the proportions of CD4 + T lymphocytes expressing chemokine receptors CCR4, CXCR3, CCR5, cutaneous lymphocyte antigen (CLA) or programmed death receptor-1 (PD-1) on the cell surface (all P < 0.001) . Compared with the SS group and EMF group, the IE group showed significant decreased proportions of CD4 + T lymphocytes expressing CCR4, CLA or PD-1 (all P < 0.001) , but significantly increased proportions of CD4 + T lymphocytes expressing CXCR3 or CCR5 (all P < 0.001) . Conclusion:Flow cytometric analysis of peripheral blood lymphocyte subsets, immunophenotypes and clonality can provide a reference for the etiological diagnosis of erythroderma, and is helpful for the differential diagnosis between lymphoma-associated erythroderma and inflammatory erythroderma.

ABSTRACT

To investigate the clinical features and prognostic significance in myelodysplastic syndrome (MDS) patients with DTA (DNMT3A,TET2,ASXL1) mutations. Clinical characteristics of 140 patients diagnosed as de novo MDS at People′s Hospital of Xinjiang Uygur Autonomous Region from September 2015 to December 2019 were retrospectively analyzed. Next-generation sequencing was used to detect 34 related genes in MDS patients. DTA mutations and the correlation with progression-free survival (PFS) and overall survival (OS) in MDS patients were evaluated. Among 140 MDS patients, DTA mutations was detected in 62 (44.3%) patients. And the positive rate of DTA mutations in IPSS-R lower-risk group was 65.4%, significantly higher than that of higher-risk group (31.8%)( P=0.000). Compared with the non-mutated group, patients with DTA mutations had a lower rate of conversion to leukemia (9.7% vs . 29.5%, P=0.004).Survival analysis showed that PFS in patients with DTA mutations was comparable as that in MDS patients without DTA mutations ( P=0.787), but the median OS was significantly shorter (16 months vs . 20 months, P=0.022).According to IPSS-R classification, the median OS in patients with and without DTA mutation was only statistically significant in the higher-risk group (15 months vs. 18 months, P=0.034).Among 62 patients with DTA mutations, 60 (96.8%) had additional gene mutations. DTA mutations were not independent prognostic factors when mutation frequency is greater than 10% were considered in Cox regression model ( P>0.05). DTA mutations often developed in the early stage of MDS, therefore they were more common in IPSS-R lower-risk subgroup which was correlated to the low rate of conversion to leukemia. In conclusion, DTA mutations are not associated with disease progression, but predict unfavorable survival when other add-on genes are mutated.

ABSTRACT

Objective:To investigate the clinical significance of serum glial fibrillary acidic protein(GFAP)level in middle-aged and elderly patients with Parkinson's disease(PD).Methods:In the prospective study, a total of 39 patients with PD hospitalized in the Department of Neurology of Zhejiang Hospital affiliated to Zhejiang University School of Medicine, and 17 healthy subjects from January 2017 to May 2021 were collected.Serum GFAP levels in the PD group and healthy control(CT)group were detected by an ultra-sensitive Simoa hypersensitive protein detection technology.The correlations of serum GFAP level with age, gender, clinical presentation type, depression score, Montreal Cognitive Assessment Scale(MOCA)score and Mini-Mental State Examination(MMSE)score were analyzed.Results:The level of serum GFAP was significantly higher in PD group(219.6±166.2)ng/L than in CT group(109.9±56.6)ng/L( P< 0.01). In PD group, there was no correlation of serum GFAP with age, gender, clinical classification, depression and MOCA score(age: r=0.042, gender: r=-0.142, depression score: r=0.076, MoCA score: r=0.014, all P>0.05); but there was a significant negative correlation between serum GFAP and MMSE score( r=-0.433, P< 0.05). Conclusions:There is a negative correlation between serum GFAP level and MMSE score, suggesting that the increase of serum GFAP might be suggestive of cognitive decline in Parkinson's disease patients to some extent, which should be paid attention to in clinical work.

ABSTRACT

Sarcopenia, referred to as myopenia, is a systemic syndrome characterized by decreased muscle mass and muscle strength, and decline of motor function.The elderly are a high incidence group of myopenia.With the aging of the world's population becoming increasingly severe, the incidence rate of sarcopenia has also increased, which has brought a heavy burden to the elderly family and society, and has become an important social health problem for the elderly.At present, there are more and more researches on sarcopenia, but the pathogenic factors of sarcopenia are complex and diverse.The prevention and treatment of sarcopenia still need to be further explored and studied.The establishment of an ideal animal model is the key premise and basis for the related research of sarcopenia.In this paper, the different modeling methods, advantages and disadvantages as well as the scope of application of sarcopenia animal models are described, which can provide reference and help for the subsequent animal experimental research of sarcopenia.

ABSTRACT

Objective:To investigate the 30-day mortality risk in elderly patients with sepsis-induced myocardial dysfunction(SIMD), and to analyze its related risk factors.Methods:This was a multicenter retrospective case-control study.A total of 254 elderly patients with sepsis or septic shock admitted to the Second Hospital of Shanxi Medical University(117 cases), the First Hospital of Shanxi Medical University(89 cases)and Shanxi Provincial People's University(48 cases)from January 2015 to December 2019 were enrolled.According to whether or not combined with SIMD, patients were divided into the SIMD group(n=68)and the control group(n=186). All patients were followed for 30 day to evaluate the rate of mortality and the related factors.Results:Among 254 elderly patients, the incidence of SIMD was 26.8%.There were significant differences between the SIMD group and the control group in age, heart rate, E/A value, left ventricular ejection fraction(LVEF), procalcitonin, lactate, C-reactive protein, troponin, N-terminal pro-B-type natriuretic peptide(NT-proBNP)and sequential organ failure assessment(SOFA)score(all P<0.05). The significant differences were found between the SIMD group and the control group in the all-cause mortality risk, the duration of invasive mechanical ventilation, ICU hospitalization time and total hospitalization days(35.3% or 24 cases vs.22.6% or 42 cases, 7.0 d vs.4.8 d, 9.5 d vs.7.5 d and 18.8 d vs.15.1 d, P<0.05). Age ≥65 years( RR=1.867), diabetes( RR=2.661), procalcitonin ≥13.2 μg/L( RR=3.307), and lactate ≥3.65 mmol/L( RR=2.964)were risk factors for SIMD, and serum troponin ≥0.08 μg/L( HR=2.019), NT-proBNP ≥537.4 ng/L( HR=4.411), lactate ≥3.65 mmol/L( HR=3.934)and LVEF <50.0%( HR=3.761)were risk factors for the mortality(all P<0.05). Conclusions:Elderly patients with the sepsis-induced SIMD have severe infections, mainly involving the left ventricle, and have an increased risk of mortality and a longer duration of hospital stays.

ABSTRACT

Objective:To investigate the effect of lateral tibial periosteum distraction on diabetic foot and vasculitis foot.Methods:A retrospective analysis of 13 patients (16 feet) who received lateral tibial periosteal distraction between June 2019 and May 2020 were included in the study. 9 males and 4 females; aged 39-77 years (average 66 years); left foot 7 cases, right foot 9 cases. 5 cases were patients with diabetic foot, 1 case was diabetic foot with arteriosclerosis obliterans, 2 cases were thromboembolic vasculitis, and 5 cases were arteriosclerosis obliterans. The tibial periosteum was dissected and a distraction device was placed. In the 3 patients with foot ulcers, tibial periosteum distraction devices were placed on the severer side. The periosteal distraction began on the third day after surgery, about 0.75 mm/d, the adjustment was done usually in two weeks. Two weeks later, the stretch plate was removed surgically. The followings were evaluated: visual analogue scale (VAS) pain score, foot peripheral oxygen saturation, foot capillary filling test, lower extremity arterial CT angiography (CTA), etc.Results:All 13 patients were followed up for 2-12 weeks, with an average of 3.85 weeks. VAS pain score: the average pain score of 13 patients with preoperative foot pain was 5.31±1.84 (range, 2-9) points, and 2 weeks after surgery, the average value was 2.46±1.39 (range, 1-6) points with statistical significance ( t=6.124, P<0.001) ; peripheral foot oxygen saturation: the average preoperative blood oxygen saturation of 12 patients was 87.83%±14.83% (range, 50%-98%), 1 patient was not detected before surgery, and 2 weeks after operation, the average blood oxygen saturation was 92.33%±7.91% (range, 75%-99%). There was no significant difference between them ( t=1.124, P=0.285). The foot skin temperature of 10 patients was 35.68±0.85 ℃ (range, 34.00-36.60 ℃) before surgery and 36.23±0.46 ℃ (range, 35.50-36.90 ℃) after surgery, and the difference was statistically significant ( t=3.197, P=0.008) . Capillary filling test: 2 weeks after operation, the capillary filling response was significantly improved. All 13 patients had improved CTA of both lower extremity arteries before operation, and 11 patients had CTA taken back after two weeks of operation. Compared with preoperative CTA, new vascular network was found in the operation limb. In addition to 1 patient with thromboangiitis obliterans (mainly suffering from foot pain, no wound symptoms), 2 of 12 patients with heart failure, renal failure and other basic diseases did not heal, and the wounds of the other 10 patients had improved significantly 1 month later. Conclusion:Lateral tibia periosteum distraction can be used to treat chronic ischemic diseases of lower extremities with satisfactory postoperative results.

ABSTRACT

Objective:To evaluate the value of mitral annulus displacement(TMAD) measured by two-dimensional speckle tracking imaging in evaluating left ventricular(LV) systolic function before and after immunoglobulin(IVIG) treatment in children with Kawasaki disease(KD).Methods:Thirty-five hospitalized children with acute KD(KD group) and 40 healthy volunteers(control group)were enrolled from September 2020 to March 2021 in the Third Affiliated Hospital of Zhengzhou University. All participants underwent echocardiography.Left ventricular ejection fraction(LVEF) and left ventricular short axis shortening(LVFS) were calculated from M-mode echocardiography. All children had their apical four-chamber and two-chamber view recorded and stored in real time, and the images of the KD group were recorded in the acute, subacute and convalescent stages, respectively. The data was analyzed by QLab 13.0 offline quantitative analysis software. The TMAD parameters between the KD group and the control group were compared. And the TMAD parameters at different periods in the KD group were compared. Pearson correlation analysis was conducted to evaluate associations between TMAD parameters and LVEF and N-terminal B-type natriuretic peptide(NT-proBNP) in children with acute KD.Results:①The parameters of TMAD AP4 MV1, TMAD AP4 MV2, TMAD AP2 MV1, TMAD AP2 MV2, TMAD AP4 Midpt, TMAD AP4 Midpt%, TMAD AP2 Midpt and TMAD AP2 Midpt% were decreased in patients with KD at different periods than those of the control group(all P<0.05), while there was no significant difference in LVEF between the two groups( P>0.05). ②After IVIG treatment, the values of TMAD AP4 MV1, TMAD AP4 MV2, TMAD AP2 MV1, TMAD AP2 MV2, TMAD AP4 Midpt, TMAD AP4 Midpt%, TMAD AP2 Midpt and TMAD AP2 Midpt% in subacute stage of KD were higher than those in acute stage(all P<0.05), the values of TMAD AP4 Midpt% and TMAD AP2 Midpt% in the convalescent stage of KD were higher than those in the subacute stage(all P<0.05). ③The parameters of TMAD were positively correlated with LVEF( r=0.36, 0.40, 0.32, 0.28, 0.42, 0.46, 0.35, 0.37; all P<0.05) and negatively correlated with NT-proBNP( r=-0.61, -0.57, -0.40, -0.60, -0.63, -0.47, -0.61, -0.36; all P<0.05). Conclusions:TMAD measured by two-dimensional speckle tracking imaging can quickly and accurately evaluate left ventricular systolic function in children with KD before and after IVIG treatment, and TMAD combined with NT-proBNP can provide a new method for clinical management of KD.
