Silenced ANP32A inhibits the growth, invasion and migration of colorectal cancer in vitro via the inactivation of AKT pathway / 南方医科大学学报

OBJECTIVE@#To investigate the effect of ANP32A silencing on invasion and migration of colon cancer cells and the influence of the activity of AKT signaling pathway on this effect.@*METHODS@#Colorectal cancer HCT116 and SW480 were transfected with a small interfering RNA targeting ANP32A via a lentiviral vector. At 24, 48 and 72 h after the transfection, the changes in cell proliferation and AKT activity in the cells were detected using MTT assay and Western blotting, respectively. HCT116 and SW480 cells were treated with the AKT agonist SC79 or its inhibitor MK2206 for 24, 48, 72 and 96 h, and the changes in cell migration and invasion ability were analyzed using Transwell chamber assay and cell proliferation was assessed using MTT assay. The effects of SC79 and MK2206 on migration and invasion abilities of HCT116 and SW480 cells with or without ANP32A silencing were examined using wound healing and Transwell chamber assays, and the changes in the expression of metadherin (MTDH), a factor associated with cells invasion and migration, was detected with Western blotting.@*RESULTS@#Lentivirus-mediated ANP32A silencing significantly down-regulated the activity of AKT and inhibited the proliferation of both HCT116 and SW480 cells (P < 0.01). The application of AKT inhibitor MK2206 obviously inhibited the proliferation, invasion and migration of the colorectal cancer cells (P < 0.05), while the AKT agonist SC79 significantly promoted the invasion and migration of the cells (P < 0.01). In HCT116 and SW480 cells with ANP32A silencing, treatment with MK2206 strongly enhanced the inhibitory effects of ANP32A silencing on cell invasion and migration (P < 0.05) and the expression of MTDH, while SC79 partially reversed these inhibitory effects (P < 0.01).@*CONCLUSION@#ANP32A silencing inhibits invasion and migration of colorectal cancer cells possibly by inhibiting the activation of the AKT signaling pathway.

The role of bronchoscopy in slide tracheoplasty in children / 中国当代儿科杂志

OBJECTIVES@#To study the role of bronchoscopy in slide tracheoplasty.@*METHODS@#A retrospective analysis was conducted on the diagnosis and treatment of four children with tracheal stenosis admitted to Hunan Provincial People's Hospital from 2017 to 2020. The role of bronchoscopy was summarized in the preoperative evaluation, intraoperative positioning and measurement, and postoperative wound evaluation and treatment during slide tracheoplasty.@*RESULTS@#Bronchoscopy evaluation before slide tracheoplasty showed that 3 of the 4 children had complete trachea rings, 2 had pulmonary artery sling, and 2 had multiple stenosis. Slide tracheoplasty was performed in the hospital on 3 children, and the midpoint of the stenosis segment was judged under bronchoscopy, and the length of the stenosis segment was measured, which assisted in the resection of the stenosis segment of the trachea. The pathogens were identified by lavage after the surgery. One child who developed scar traction 9 months after slide tracheoplasty in another hospital was improved by interventional treatment under bronchoscopy. Mucosal changes were found under bronchoscopy in 2 children 4 days after surgery, and the treatment plan was adjusted. One month after surgery, 2 children had granulation hyperplasia, which was improved by cryotherapy under bronchoscopy. One child abandoned treatment due to anastomotic necrosis and died. Three survivors were followed up for over 6 months with good prognosis, but all had tracheobronchial malacia.@*CONCLUSIONS@#Bronchoscopy can be used for the management of slide tracheoplasty in children with tracheal stenosis, which is helpful to postoperative rehabilitation and follow-up.

Scope review of human caring for patients by head nurses / 中华医院管理杂志

Objective:To explore the current practice of head nurses′ human caring for patients at home and abroad, and integrate those effective measures and effect evaluation methods, so as to provide reference for nursing administrators.Methods:A framework was built on the scope review method proposed by Arksey and O′Malley, and such search terms as head nurse/nursing administrator, human caring/care/human-based, sick person/patient, nursing supervisory/charge nurse/head nurse/nurse administrator/nurse manager/nurse executive, empathy/care/compassion, patient/client were used. CNKI, Wanfang database, VIP, Chinese Medical Association Journal Full-text Database, Medical Knowledge Network (PubMed, Elsevier, Springer, Wiley, OVID, EBSCO) and the Cochrane Library were searched from their initiation to November 29, 2022. Two researchers independently screened and extracted basic characteristics of the literature, as well as the measures used by the head nurses to implement human caring for patients and the effect evaluation tools.Results:A total of 57 articles were included. This paper reviewed the measures of human caring for patients at both levels of head nurses as direct caregivers and as organizers.The measures at the level of direct caregivers included implementing human caring in their ward rounds, creating a caring atmosphere, setting up a head nurse reception day, interviewing the care needs of patients and their families, innovating working methods based on the perspective of human caring, and caring communication with patients and their families; measures at the level of organizers included building a nursing human caring mode with specialist characteristics, building a human caring mode for different patient groups, strengthening the training of nurses′ human caring ability and literacy, building a caring environment and atmosphere, simplifying the nursing work process, and establishing a continuous and diversified nurse-patient communication mode, continuing human caring for discharged patients, organizing participation of nurses in social practices of human caring, setting up caring posts, and conducting care supervision and quality control. Patient satisfaction survey was used to evaluate the practical effects of human caring, but the evaluation objects were nurses or nursing services.Conclusions:Head nurses play an important role in the implementation of human caring, and a variety of measures can be taken to directly or indirectly implement human caring for patients. It is suggested to build more human caring modes to cover more specialties and patient groups, and improve the patient satisfaction evaluation tools with head nurses as the evaluation object.

Differential diagnosis between alpha-fetoprotein-negative hepatocellular carcinoma without cirrhosis and hepatic focal nodular hyperplasia / 中华肝胆外科杂志

Objective:To study the clinical and MRI features of alpha-fetoprotein-negative hepatocellular carcinoma without cirrhosis to compare with those of hepatic focal nodular hyperplasia (FNH) to arrive at a correct differential diagnosis.Methods:The data of 105 patients who underwent liver surgery for alpha-fetoprotein-negative hepatocellular carcinomas without cirrhosis at Zhongshan Hospital, Fudan University and the Traditional Chinese Medical Hospital of Nantong from March 2017 to November 2020 were retrospectively studied. There were 109 lesions in 95 males and 10 females. These patients had the age of (60.2±9.9) years. The data of 88 patients who were diagnosed to have hepatic FNH during the study period were collected, and there were 99 lesions in 36 males and 52 females. These patients had the age of (32.8±9.5) years. Variables including age, history of hepatitis B virus infection, T 1 weighted imaging (T 1WI), T 2 weighted imaging (T 2WI), diffusion-weighted imaging (DWI), apparent diffusion coefficient (ADC), enhancement mode, lesion shape, lesion boundary and capsule were compared between the two groups. Results:The age and the proportion of patients with a history of hepatitis B in the alpha-fetoprotein-negative hepatocellular carcinoma and without cirrhosis group were significantly higher than those in the hepatic FNH group (both P<0.05). The proportion of lesions with quasi-circular shape, clear boundary and with capsule in hepatocellular carcinoma group were significantly higher than those in the hepatic FNH group (all P<0.05). There were also significant differences in the T 1WI, T 2WI, enhancement modes, DWI, and ADC map between the two groups of lesions (all P<0.05). The areas under the receiver operating characteristic curve for the alpha-fetoprotein-negative hepatocellular carcinoma without cirrhosis by the age >45.5 year, with a history of hepatitis B, with clear lesion boundary, with a "washin and washout" enhanced mode and with lesion encapsulation were 0.97(95% CI: 0.95-0.99), 0.79(95% CI: 0.72-0.85), 0.78(95% CI: 0.72-0.85), 0.94(95% CI: 0.90-0.97), 0.99(95% CI: 0.98-1.00) respectively. Conclusions:The presence of a capsule, clear lesion boundary and "washin and washout" enhanced mode are helpful in differentiating alpha-fetoprotein-negative hepatocellular carcinoma without cirrhosis with hepatic FNH.

Evidence-based practice of self-made tracheal catheter fixation band in prevention of unplanned extubation / 中华危重病急救医学

With the development of medical technology, the fixation method of the oral duct is constantly updated, and the selection of a relatively safe, effective, simple and fast fixation method of the oral duct has been widely concerned. However, the use of traditional 3M I-shaped tape fixation needs to be cut, which wastes time and easily leads to the outward displacement of the tracheal tube, and is easy to be soaked by oral secretions, resulting in facial skin damage. Therefore, the medical staffs of the department of critical care medicine of Hengshui People's Hospital designed a self-made tracheal catheter fixing band (composed of the main structure, the fixed band, the internal adjusting structure and the internal structure of the fixed block), and obtained the national utility model patent (ZL 2018 2 0508681.6). The inner side of the fixing band is fixed with a spongy body, which can absorb the secretions around the mouth to avoid the moist condition around the mouth and cheek skin. Meanwhile, the endotracheal catheter is fixed with the help of the card slot, hinge and other structures, which can fully ensure the fixation effect. A total of 80 patients undergoing airway intubation were admitted to the department of critical care medicine of our hospital from October 2020 to September 2021. They were divided into observation group and control group according to intubation time (single number and double number), with 40 patients in each group. The observation group was fixed with self-made tracheal catheter fixation band. Through evidence-based practice path, relevant literatures at home and abroad were searched for clinical practice basis, and the practice plan was formulated and implemented. The control group was fixed with 3M tape + inch tape according to the traditional method. The fixation of tracheal tube and the degree of facial skin injury were compared between the two groups. All patients were included in the final analysis without shedding cases. Severe catheter displacement occurred in 3 patients (7.5%) in the control group, and no severe catheter displacement occurred in the observation group. The incidence of facial skin injury in the observation group was significantly lower than that in the control group [25.0% (10/40) vs. 55.0% (22/40), P < 0.05]. Moreover, the fixation time of the observation group was significantly shorter than that of the control group (minute: 12.11±1.69 vs 17.59±1.27, P < 0.05). The application of self-made tracheal catheter fixation band can shorten the fixation time of tracheal catheter and reduce the incidence of unplanned endotracheal extubation (UEE) and facial skin injury, which is worthy of clinical promotion and application.

Clinical value of remnant lipoproteins and low density lipoprotein cholesterol particle concentration detected by vertical auto profile on the diagnosis of carotid plaque / 中华检验医学杂志

Objective:To explore the clinical value of peripheral remnant lipoproteins (RLP), low density lipoprotein cholesterol particle (LDL-P) and sdLDL particle (sdLDL-P) measurement in the diagnosis of carotid plaque, so as to provide practical basis for the accurate diagnosis of carotid plaque and the control of carotid plaque related cardiovascular and cerebrovascular diseases.Methods:People who underwent carotid plaque ultrasound examination in Xingtai Third Hospital , from January 2020 to June 2021 were selected as the research object. According to the ultrasound results, they were divided into carotid plaque group ( n=146) and control group without carotid plaque ( n=149). The fasting RLP, LDL-P and sdLDL-P of the two groups were measured by vertical auto profile (VAP) centrifugal separation phase, and the fasting TG and LDL-C were detected by routine mixed phase method. The indexes were compared between the two groups and the true positive rate, true negative rate, false positive rate and false negative rate of the diagnosis of carotid plaque were analyzed. The receiver operating characteristic curve of each test index was drawn, and AUC was used to evaluate the clinical diagnostic value of each test index for carotid plaque. Results:The levels of RLP, LDL-P and sdLDL-P in carotid plaque group were significantly higher than those in non-carotid plaque group ([1.07±0.36] mmol/L vs [0.59±0.17] mmol/L,[1 300±370] nmol/L vs [781±215] nmol/L,[435±139] nmol/L vs [156±59] nmol/L, all P<0.01). The true positive rate (78.08% [114/146],81.51% [119/146]) and true negative rate (84.56% [126/149], 86.58%[129/149]) of serum RLP and LDL-P for the diagnosis of carotid plaque were significantly higher than TG (58.90%[86/146], 43.62%[65/149]) and LDL-C (59.59% [87/146], 46.98% [70/149]), and the false positive rate (15.44% [23/149], 13.42% [20/149]) and false negative rate (21.92% [32/146], 18.49% [27/146]) were significantly lower than TG (56.38% [84/149], 41.10% [60/146]) and LDL-C (53.02% [79/149], 40.41% [59/146], all P<0.01). The AUC of the ROC curve of RLP (0.890), LDL-P (0.902) and sdLDL-P (0.973) for the diagnosis of carotid plaque was higher than TG (0.682) and LDL-C (0.712). The AUC of ROC curve of the RLP combined with sdLDL-P (0.977) for the diagnosis of carotid plaque was higher than the RLP and sdLDL-P (all P<0.01). Conclusion:The serum RLP, LDL-P and sdLDL-P can be used as indicators of carotid plaque, and their clinical diagnostic value are superior to TG and LDL-C; the combined diagnostic effect of lipoprotein subclass is better than that of single index alone.

Quantitation and content investigation of bilirubin in cultured cow-bezoar / 中国中药杂志

A determination method for bilirubin in cultured cow-bezoar was developed in this study, with which the bilirubin in 15 batches of samples was quantified. The samples were first processed with 10% oxalic acid solution for the conversion of bilirubin from conjugated to unconjugated, followed by the extraction with dichloromethane. Then the obtained sample solutions were analyzed at 450 nm by HPLC[chromatographic column: Agilent TC-C_(18)(4.6 mm × 250 mm, 5 μm); mobile phase: acetonitrile and 1% glacial acetic acid aqueous solution(95∶5); flow rate: 1.0 mL·min~(-1)]. The bilirubin content in the 15 batches of cultured cow-bezoar was ranged from 21.9% to 41.7% with the average of 32.4%. The proposed method is accurate and reliable, thus making it suitable for the quantitation of bilirubin in cultured cow-bezoar and its quality assessment and control.

Progress in understanding hepatic fibrosis and renal fibrosis based on the gut-liver-kidney axis / 药学学报

Fibrosis is a pathological process of abnormal hyperplasia and excessive deposition of extracellular matrix during the process of repair after tissue and organ damage. Injury/inflammation caused by variously chronic diseases is a major trigger for fibrogenesis. Fibrosis of the liver and kidney is a common organ fibrosis. Recently, the intestinal microbiota has been shown to be extensively involved in the development of liver and kidney diseases, which may follow from changes in the intestinal microbial composition and intestinal integrity. This promotes the development of liver and/or kidney fibrosis through endocrine, cell signaling and other pathways. This paper reviews the research progress in understanding liver fibrosis and kidney fibrosis based on the gut-liver-kidney axis, which may be helpful for providing new strategies and theoretical basis for the diagnosis and treatment of hepatic and renal fibrosis.

Investigation of chemical profile of bile acids and determination of them in cultured Bovis Calculus with UPLC-QDA / 中国中药杂志

In this study, 10 batches of samples of cultured Bovis Calculus(cow-bezoar) were determined for the investigation of chemical profile of bile acids with the UPLC-QDA method established. The results showed that nine common bile acids, cholic acid(CA), deoxycholic acid(DCA), chenodeoxycholic acid(CDCA), taurocholic acid(TCA), taurodeoxycholic acid(TDCA), taurochenodeoxycholic acid(TCDCA), glycocholic acid(GCA), glycodeoxycholic acid(GDCA) and glycochenodeoxycholic acid(GCDCA), were founded in samples and 7 bile acids were quantified except GDCA and GCDCA. In these samples, unconjugated bile acids, the major type of bile acids, accounted for more than 97% of all types of bile acids. As for unconjugated bile acids, CA was the most major bile acid in cultured cow-bezoar and it was about twice as much as DCA. The relative low-cost method established in the current study is accurate, rapid and sensitive, which is suitable for the studies of other drugs from animal bile.

Analysis of Molecular Mechanism of Dingxiang Shiditang for Hiccup and Vomit Based on Integrated Pharmacology / 中国实验方剂学杂志

Objective: The classical formula of Dingxiang Shiditang can be used for hiccup and vomit which caused by many reasons,its molecular mechanism of this formula was investigated.Method: Based on the integrated pharmacology platform of traditional Chinese medicine,the potential molecular mechanism of Dingxiang Shiditang was revealed from the dimensions of multi-components and multi-targets.Result: There were 89 compounds related to hiccup and vomit of Dingxiang Shiditang,and there was 1 common target[cannabinoid receptor 1(CNR1)].On the one hand,CNR1 could inhibit the occurrence of hiccup and vomit by inhibiting the release of γ-aminobutyric acid(GABA),dopamine,5-hydroxytryptamine(5-HT);on the other hand,CNR1 could inhibit gastrointestinal motility and delay gastric emptying,and it was speculated that CNR1 may play a role in regulating gastrointestinal motility through brain-gut axis.Meanwhile,the mechanism of Dingxiang Shiditang may be related to nucleotide metabolism and nervous system.Conclusion: Dingxiang Shiditang may regulate gastrointestinal motility by affecting the release of neurotransmitters,mitochondrial energy metabolism,and achieve its effect on hiccup and vomit based on the joint intervention of multiple targets and multiple pathways.

The effects of extracorporeal shock wave therapy on the lower limb function and articular cartilage of pa-tients with knee osteoarthritis / 中华物理医学与康复杂志

Objective To evaluate the effect and safety of extracorporeal shock wave therapy ( ESWT) for knee osteoarthritis ( KOA) and its effect on the articular cartilage. Methods Sixty-three persons with KOA were randomly divided into an ESWT group ( n=32) and a control group ( n=31) . Both groups received routine knee mus-cle strength training, but the ESWT group was also given ESWT ( a total of 2000 pulses at 8 Hz and 2.5 bar pressure) once a week for four consecutive weeks. The control group was given sham therapy at 0.2 bar with the rest of the pa-rameters the same as in the ESWT group. All of the subjects were assessed using a visual analogue scale ( VAS) , the Western Ontario and McMaster Universities Osteoarthritis Score ( WOMAC) , the Lequesne Index and knee cartilage T2 values before as well as one and 8 weeks after the intervention. Results The average VAS score, WOMAC in-dex, and Lequesne index of the ESWT group at 8 weeks after the treatment were significantly better than those before the intervention, and significantly better than the control group' s averages. The T2 values of the ESWT group at 8 weeks after the treatment were significantly better than before the intervention, though not significantly different from those of the control group at that point. No serious adverse reactions occurred in either group, and all of the minor ad-verse reactions had disappeared before the end of the assessment period. Conclusion ESWT can significantly im-prove the lower limb functioning of KOA patients, and its influence on knee cartilage is within the safe range.

Screening and intervention of resistant hypertension in the community / 中华全科医师杂志

Objective To assess the screening and intervention techniques for resistant hypertension in the community.Methods Random sampling method was used to recruit 1 171 hypertensive patients from two communities in Hangzhou and Zhuji cities of Zhejiang province form October 2015 to september 2016.Among them,97 patients with resistant hypertension were identified with the Three-steps-flow screening method and the individualized intervention was given.The standardized treatment and lifestyle changes were compared before and after intervention.Results Among 97 patients with resistant hypertension,7 cases of pseudo resistant hypertension were detected;there were 2 cases with thyroid disease history,48 cases with snoring history and 1 case with sleep apnea syndrome.The life style intervention and standardized medication guidance were given to 90 patients with resistant hypertension according to the individual risk factors.After one year of intervention,the results showed that the rate of normalized blood pressure was 83.5％ (75/90) and the rate of standardized medication increased from 14.4％(13/90) to 90.0％ (81/90),the rate of medication compliance increased from 46.7％(42/90) to 95.6％(86/90),the blood pressure control rate increased from 12.2％(11/90) to 77.8％(70/90),and the average systolic blood pressure and diastolic blood pressure levels were decreased by 20.4 mmHg (1 mmHg=0.133 kPa) and 15.5 mmHg.The life style of patients with resistant hypertension was remarkably changed,56.7％(51/90) of patients took exercise regularly,high salt/high calorie diet decreased from 37.8％(34/90) to 11.1％(10/90),the proportion of the obese went down to 16.7％(15/90).Conclusion With the application of resistant hypertension screening and intervention,there are remarkable improvement in blood pressure control and life style changes for patients with resistant hypertension in the community.
