Study on the status of turnover intention and its influencing factors of 382 hemato-oncology nurses / 中华劳动卫生职业病杂志

Objective: To explore the status of turnover intention and its influencing factors of hemato-oncology nurses. Methods: From September to November 2021, the convenience sampling method was used to select 382 hemato-oncology nurses from 8 tertiary grade A general hospitals in Shandong Province. The general information questionnaire, the Chinese Nurses' Work Stressor Scale, the Psychological Capital Questionnaire and the Turnover Intention Questionnaire were used to investigate the general situation, occupational stress, psychological capital and turnover intention of the objects. The correlations between the turnover intention, occupational stress and psychological capital of the objects were analyze by Pearson correlation. And the multiple linear regression was used to analyze the influencing factors of turnover intention. A structural equation model was used to analyze the effect path of occupational stress and psychological capital on turnover intention. Results: The total turnover intention score of hemato-oncology nurses was (14.25±4.03), with the average item score of (2.38±0.67). The occupational stress score of hemato-oncology nurses was (71.57±14.43), and the psychological capital score was (91.96±15.29). The results of correlation analysis showed that the turnover intention of hemato-oncology nurses was positively correlated with occupational stress, and was negatively correlated with psychological capital (r=0.599, -0.489, P<0.001). Multiple linear regression analysis showed that married (β=-0.141), psychological capital (β=-0.156) and occupational stress (β=0.493) were the influencing factors of turnover intention of hemato-oncology nurses (P<0.05). The path analysis of structural equation model showed that the direct effect of occupational stress on turnover intention of hemato-oncology nurses was 0.522, and the intermediary effect of psychological capital on turnover intention was 0.143 (95%CI: 0.013-0.312, P<0.05), accounting for 21.5% of the total effect. Conclusion: The turnover intention of hemato-oncology nurses is at a high level, hospital and administrators should focus on the psychological state of unmarried nurses. By improving the psychological capital of nurses, to reduce occupational stress and turnover intention.

Pathological significance of plasma cell infiltration in diagnosing lymph node diseases / 中华病理学杂志

Objective: To investigate the value of plasma cells for diagnosing lymph node diseases. Methods: Common lymphadenopathy (except plasma cell neoplasms) diagnosed from September 2012 to August 2022 were selected from the pathological records of Changhai Hospital, Shanghai, China. Morphological and immunohistochemical features were analyzed to examine the infiltration pattern, clonality, and IgG and IgG4 expression of plasma cells in these lymphadenopathies, and to summarize the differential diagnoses of plasma cell infiltration in common lymphadenopathies. Results: A total of 236 cases of lymphadenopathies with various degrees of plasma cell infiltration were included in the study. There were 58 cases of Castleman's disease, 55 cases of IgG4-related lymphadenopathy, 14 cases of syphilitic lymphadenitis, 2 cases of rheumatoid lymphadenitis, 18 cases of Rosai-Dorfman disease, 23 cases of Kimura's disease, 13 cases of dermal lymphadenitis and 53 cases of angioimmunoblastic T-cell lymphoma (AITL). The main features of these lymphadenopathies were lymph node enlargement with various degrees of plasm cell infiltration. A panel of immunohistochemical antibodies were used to examine the distribution of plasma cells and the expression of IgG and IgG4. The presence of lymph node architecture could help determine benign and malignant lesions. The preliminary classification of these lymphadenopathies was based on the infiltration features of plasma cells. The evaluation of IgG and IgG4 as a routine means could exclude the lymph nodes involvement of IgG4-related dieases (IgG4-RD), and whether it was accompanied by autoimmune diseases or multiple-organ diseases, which were of critical evidence for the differential diagnosis. For common lesions of lymphadenopathies, such as Castleman's disease, Kimura's disease, Rosai-Dorfman's disease and dermal lymphadenitis, the expression ratio of IgG4/IgG (>40%) as detected using immunhistochemistry and serum IgG4 levels should be considered as a standard for the possibility of IgG4-RD. The differential diagnosis of multicentric Castleman's diseases and IgG4-RD should be also considered. Conclusions: Infiltration of plasma cells and IgG4-positive plasma cells may be detected in some types of lymphadenopathies and lymphomas in clinicopathological daily practice, but not all of them are related to IgG4-RD. It should be emphasized that the characteristics of plasma cell infiltration and the ratio of IgG4/IgG (>40%) should be considered for further differential diagnosis and avoiding misclassification of lymphadenopathies.

Objective To understand the seasonal and etiological characteristics of the epidemic situation of cluster fever in Pudong New Area, Shanghai, and to provide a scientific basis for the formulation of prevention and control strategies. Methods The epidemic data of cluster fever in Pudong New Area of Shanghai from 2013 to 2021 were collected, and the data were analyzed by concentration degree and circular distribution methods. Results From 2013 to 2021, there were 109 cases of cluster fever reported in Pudong New Area, with primary schools reporting the most cases, 77 cases (70.64%). The M value was 0.59. Circular distribution results showed that angle dispersion index r value was 0.54, the average angle was 357.32°, and the average angle of Rayleigh’s test Z value was 32.07. The peak day was December 28, and the peak period was from October 25 to March 3 of the following year. The cluster of fever in Pudong New Area was mainly caused by influenza virus. Most cases were single pathogen infection, and some were double pathogen infection. Influenza A virus had the highest detection rate in both single pathogen infection and double pathogen infection. Conclusion Primary schools are the focus of prevention and control of the cluster of fever in Pudong New Area. The epidemic situation of cluster fever has a strong seasonal characteristic, and the peak of incidence is from late October to early March of the next year. Respiratory pathogens such as influenza virus are the main causes of the epidemic situation.

Efficacy of perioperative use of tigecycline in preventing infection and incidence of hypofibrinogenemia in liver transplant recipients / 器官移植

Objective To evaluate the efficacy of perioperative use of tigecycline in preventing infection and the incidence of hypofibrinogenemia in liver transplant recipients. Methods Clinical data of 40 liver transplant recipients given with tigecycline to prevent infection were retrospectively analyzed. The incidence of infection in recipients and donor-derived infection were analyzed. The changes of clinical indexes in recipients during, upon the completion and (7±2) d after tigecycline treatment were analyzed, respectively. The incidence and treatment of hypofibrinogenemia were summarized. Results Among 40 liver transplant recipients, 2 cases were infected by aspergillus niger and cytomegalovirus, out of the antibacterial spectrum of tigecycline. After adjusting the anti-infection regimen, the infection was properly controlled. Liver allografts were positive for relevant culture in 9 cases, whereas none of them progressed into donor-derived infection. Approximately at postoperative 2 weeks, all 40 recipients restored liver function and were discharged from hospital. Among them, 6 recipients developed hypofibrinogenemia complicated with coagulation disorder at postoperative 2-4 d, whereas transaminase level, bilirubin level and infection-related indexes were gradually decreased after liver transplantation, and albumin level was stable. After supplemented with human fibrinogen and prothrombin complex, coagulation function was improved, but fibrinogen level persistently declined. After terminating use of tigecycline, fibrinogen level was gradually restored to normal range, which might be an adverse drug reaction induced by tigecycline. Conclusions Perioperative anti-infection regimen including tigecycline may reduce the incidence of infection caused by sensitive bacteria in liver transplant recipients. Nevertheless, the incidence of hypofibrinogenemia should be intimately monitored throughout the use of tigecycline.

Study on the correlation between retinal microvascular density and damage to visual field in patients with sellar region tumor / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To evaluate the changes of retinal microvascular density in patients with sellar region tumor, and its correlation with the damage to visual field, and to explore its application value in evaluating optic nerve injury of those patients.METHODS: Cross-sectional study. A total of 157 patients(292 eyes)with sellar region tumor, including 82 cases(152 eyes)of pituitary adenoma and 75 cases(140 eyes)of craniopharyngioma, were selected from neurosurgery department and ophthalmology department of Beijing Tiantan Hospital, Capital Medical University between October 2018 and May 2022. A total of 90 people(180 eyes)during the same period, including the family members of patients, students and staff in Beijing Tiantan Hospital, Capital Medical University were collected as control group. All participants underwent optical coherence tomography angiography(OCTA)examination. The changes of retinal microvascular density and its correlation with visual field parameters were compared between the two groups.RESULTS: In patients with sellar region tumor, the radial peripapillary capillary(RPC)and superficial retinal capillary plexus(SRCP)density were significantly lower than that in the control group [50.81%(46.49%, 53.49%)vs. 52.78%(50.73%, 54.51%)and 50.57%(48.13%, 52.73%)vs. 51.63%(49.78%, 53.02%), all P<0.05]. The RPC density in the craniopharyngioma group was lower than that in the pituitary adenoma group [49.71%(44.33%, 53.14%)vs. 51.37%(47.42%, 53.95%), P<0.05]. The MD, PSD and VFI of the sellar region tumor group were -4.33(-12.22, -1.85)dB, 3.37(1.91, 8.82)dB and 92%(65%, 97%)respectively. RPC density of patients with sellar region tumor was positively correlated with MD and VFI, and was negatively correlated with PSD. The SRCP density of each quadrant was positively correlated with MD, and was positively correlated with VFI except Para-T and it was negatively correlated with PSD(all P<0.05).CONCLUSION: Retinal microvascular changes were present in patients with sellar region tumor. Lower vessel density indicates more severe damage to visual field. In the clinic, visual field examinations combined with OCTA were helpful to find the optic nerve injury of patients.

Ganoderma lucidum Polysaccharides Inhibit Malignant Phenotype of Hepatocellular Carcinoma Cells by Regulating PI3K/Akt Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo investigate the effect of Ganoderma lucidum polysaccharides （GLP） on the proliferation， migration， cycle， and apoptosis of hepatocellular carcinoma SK­HEP­1 and Huh­7 cells and to explore the underlying mechanism. MethodSK-HEP-1 and Huh-7 cells were classified into the blank group and low-， medium-， and high-dose GLP groups （3.5， 7， 14 g·L-1）. The proliferation of the cells was examined by cell counting kit-8 （CCK­8） assay， and the migration by scratch assay. Cell cycle was measured by flow cytometry and apoptosis was detected based on Hoechst33258 staining. In addition， the expression of phosphatidylinositol 3-kinase （PI3K）， protein kinase B （Akt）， phosphorylated PI3K （p­PI3K）， and phosphorylated Akt （p­Akt） in the cells was determined by Western blot. ResultCompared with the blank group， the three doses of GLP reduced the proliferation and migration of SK­HEP­1 and Huh­7 cells （P<0.05）， increased the percentage of cells in G1 phase （P<0.05）， and decreased percentage of cells in S and G2 phase （P<0.05）. In addition， the three doses can induce apoptosis of both SK-HEP-1 and Huh-7 cells， particularly the high dose. Moreover， the three doses of GLP lowered the levels of p­PI3K and p­Akt （P<0.05）. ConclusionGLP significantly inhibited the malignant phenotype of SK-HEP-1 and Huh-7 cells through the PI3K/Akt signaling pathway.

Therapeutic effect of ursodeoxycholic acid-berberine supramolecular nanoparticles on ulcerative colitis based on supramolecular system induced by weak bond / 中国中药杂志

Ulcerative colitis(UC) is a recurrent, intractable inflammatory bowel disease. Coptidis Rhizoma and Bovis Calculus, serving as heat-clearing and toxin-removing drugs, have long been used in the treatment of UC. Berberine(BBR) and ursodeoxycholic acid(UDCA), the main active components of Coptidis Rhizoma and Bovis Calculus, respectively, were employed to obtain UDCA-BBR supramolecular nanoparticles by stimulated co-decocting process for enhancing the therapeutic effect on UC. As revealed by the characterization of supramolecular nanoparticles by field emission scanning electron microscopy(FE-SEM) and dynamic light scattering(DLS), the supramolecular nanoparticles were tetrahedral nanoparticles with an average particle size of 180 nm. The molecular structure was described by ultraviolet spectroscopy, fluorescence spectroscopy, infrared spectroscopy, high-resolution mass spectrometry, and hydrogen-nuclear magnetic resonance(H-NMR) spectroscopy. The results showed that the formation of the supramolecular nano-particle was attributed to the mutual electrostatic attraction and hydrophobic interaction between BBR and UDCA. Additionally, supramolecular nanoparticles were also characterized by sustained release and pH sensitivity. The acute UC model was induced by dextran sulfate sodium(DSS) in mice. It was found that supramolecular nanoparticles could effectively improve body mass reduction and colon shortening in mice with UC(P<0.001) and decrease disease activity index(DAI)(P<0.01). There were statistically significant differences between the supramolecular nanoparticles group and the mechanical mixture group(P<0.001, P<0.05). Enzyme-linked immunosorbent assay(ELISA) was used to detect the serum levels of tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6), and the results showed that supramolecular nanoparticles could reduce serum TNF-α and IL-6 levels(P<0.001) and exhibited an obvious difference with the mechanical mixture group(P<0.01, P<0.05). Flow cytometry indicated that supramolecular nanoparticles could reduce the recruitment of neutrophils in the lamina propria of the colon(P<0.05), which was significantly different from the mechanical mixture group(P<0.05). These findings suggested that as compared with the mechanical mixture, the supramolecular nanoparticles could effectively improve the symptoms of acute UC in mice. The study provides a new research idea for the poor absorption of small molecules and the unsatisfactory therapeutic effect of traditional Chinese medicine and lays a foundation for the research on the nano-drug delivery system of traditional Chinese medicine.

Spatiotemporally resolved metabolomics and isotope tracing reveal CNS drug targets

Deconvolution of potential drug targets of the central nervous system (CNS) is particularly challenging because of the complicated structure and function of the brain. Here, a spatiotemporally resolved metabolomics and isotope tracing strategy was proposed and demonstrated to be powerful for deconvoluting and localizing potential targets of CNS drugs by using ambient mass spectrometry imaging. This strategy can map various substances including exogenous drugs, isotopically labeled metabolites, and various types of endogenous metabolites in the brain tissue sections to illustrate their microregional distribution pattern in the brain and locate drug action-related metabolic nodes and pathways. The strategy revealed that the sedative-hypnotic drug candidate YZG-331 was prominently distributed in the pineal gland and entered the thalamus and hypothalamus in relatively small amounts, and can increase glutamate decarboxylase activity to elevate γ-aminobutyric acid (GABA) levels in the hypothalamus, agonize organic cation transporter 3 to release extracellular histamine into peripheral circulation. These findings emphasize the promising capability of spatiotemporally resolved metabolomics and isotope tracing to help elucidate the multiple targets and the mechanisms of action of CNS drugs.

Pulse pressure loss after extracorporeal cardiopulmonary resuscitation is an independent predictor of ECMO weaning failure / 中华危重病急救医学

OBJECTIVE@#To analyze the predictors of successful weaning off extracorporeal membrane oxygenation (ECMO) after extracorporeal cardiopulmonary resuscitation (ECPR).@*METHODS@#The clinical data of 56 patients with cardiac arrest who underwent ECPR in Hunan Provincial People's Hospital (the First Affiliated Hospital of Hunan Normal University) from July 2018 to September 2022 were retrospectively analyzed. According to whether ECMO was successfully weaning off, patients were divided into the successful weaning off group and the failed weaning off group. The basic data, duration of conventional cardiopulmonary resuscitation (CCPR, the time from cardiopulmonary resuscitation to ECMO), duration of ECMO, pulse pressure loss, complications, and the use of distal perfusion tube and intra-aortic balloon pump (IABP) were compared between the two groups. Univariate and multivariate Logistic regression analyses were performed to identify the risk factors for weaning failure of ECMO.@*RESULTS@#Twenty-three patients (41.07%) were successfully weaned from ECMO. Compared with the successful weaning off group, patients in the failed weaning off group were older (years old: 46.7±15.6 vs. 37.8±16.8, P < 0.05), higher incidence of pulse pressure loss and ECMO complications [81.8% (27/33) vs. 21.7% (5/23), 84.8% (28/33) vs. 39.1% (9/23), both P < 0.01], and longer CCPR time (minutes: 72.3±19.5 vs. 54.4±24.6, P < 0.01), shorter duration of ECMO support (hours: 87.3±81.1 vs. 147.7±50.8, P < 0.01), and worse improvement in arterial blood pH and lactic acid (Lac) levels after ECPR support [pH: 7.1±0.1 vs. 7.3±0.1, Lac (mmol/L): 12.6±2.4 vs. 8.9±2.1, both P < 0.01]. There were no significant differences in the utilization rate of distal perfusion tube and IABP between the two groups. Univariate Logistic regression analysis showed that the factors affecting the weaning off ECMO of ECPR patients were pulse pressure loss, ECMO complications, arterial blood pH and Lac after installation [pulse pressure loss: odds ratio (OR) = 3.37, 95% confidence interval (95%CI) was 1.39-8.17, P = 0.007; ECMO complications: OR = 2.88, 95%CI was 1.11-7.45, P = 0.030; pH after installation: OR = 0.01, 95%CI was 0.00-0.16, P = 0.002; Lac after installation: OR = 1.21, 95%CI was 1.06-1.37, P = 0.003]. After adjusting for the effects of age, gender, ECMO complications, arterial blood pH and Lac after installation, and CCPR time, showed that pulse pressure loss was an independent predictor of weaning failure in ECPR patients (OR = 1.27, 95%CI was 1.01-1.61, P = 0.049).@*CONCLUSIONS@#Early loss of pulse pressure after ECPR is an independent predictor of failed weaning off ECMO in ECPR patients. Strengthening hemodynamic monitoring and management after ECPR is very important for the successful weaning off ECMO in ECPR.

Clinical characteristics and risk factors for early-onset necrotizing enterocolitis in preterm infants with very/extremely low birth weight / 中国当代儿科杂志

OBJECTIVES@#To investigate the clinical characteristics and risk factors for early-onset necrotizing enterocolitis (NEC) in preterm infants with very/extremely low birth weight (VLBW/ELBW).@*METHODS@#A retrospective analysis was performed on the medical data of 194 VLBW/ELBW preterm infants with NEC who were admitted to Children's Hospital Affiliated to Zhengzhou University from January 2014 to December 2021. These infants were divided into early-onset group (onset in the first two weeks of life; n=62) and late-onset group (onset two weeks after birth; n=132) based on their onset time. The two groups were compared in terms of perinatal conditions, clinical characteristics, laboratory examination results, and clinical outcomes. Sixty-two non-NEC infants with similar gestational age and birth weight who were hospitalized at the same period as these NEC preterm infants were selected as the control group. The risk factors for the development of early-onset NEC were identified using multivariate logistic regression analysis.@*RESULTS@#Compared with the late-onset group, the early-onset group had significantly higher proportions of infants with 1-minute Apgar score ≤3, stage III NEC, surgical intervention, grade ≥3 intraventricular hemorrhage, apnea, and fever or hypothermia (P<0.05). The multivariate logistic regression analysis showed that feeding intolerance, blood culture-positive early-onset sepsis, severe anemia, and hemodynamically significant patent ductus arteriosus were independent risk factors for the development of early-onset NEC in VLBW/ELBW preterm infants (P<0.05).@*CONCLUSIONS@#VLBW/ELBW preterm infants with early-onset NEC have more severe conditions compared with those with late-onset NEC. Neonates with feeding intolerance, blood culture-positive early-onset sepsis, severe anemia, or hemodynamically significant patent ductus arteriosus have a higher risk of early-onset NEC.

Study on anatomical parameters of adult lumbar intervertebral disc and endplate based on CT / 中国骨伤

OBJECTIVE@#To provide basic data for clinical application and individualized design of lumbar disc prostheses by measuring the anatomical parameters of lumbar intervertebral discs and endplates in healthy adults with CT three-dimensional reconstruction technology.@*METHODS@#A retrospective analysis was performed on 200 males and 200 females with normal lumbar spine who were admitted to the imaging center or outpatient department of the Second Affiliated Hospital of Xinjiang Medical University from September 2019 to December 2020. The age ranged from 20 to 60 years old, with an average of (40.61±11.22) years old. The measurement segment was L1-S1 intervertebral disc, and the measurement indicators included the axial anteroposterior diameter and transverse diameter of the intervertebral disc, sagittal anterior, middle and posterior height, coronal left and right height, intervertebral space angle, and transverse and anteroposterior diameters of the upper and lower endplates of each vertebral body.@*RESULTS@#①In terms of gender, the anatomical parameters of L1-S1 disc axial diameter, transverse diameter, sagittal anterior, middle and posterior height, left and right coronal height and intervertebral space angle were all higher in males than in females(P<0.05), and the anatomical parameters of upper and lower endplates of L1-S1 vertebral body were higher in males than in females(P<0.001). ②In comparison of sagittal height of anterior, middle and posterior intervertebral discs, the sagittal height of L1-L5 intervertebral discs was middle-high > anterior-high > posterior-high(P<0.001), while that of L5S1 intervertebral disc was anterior-high > middle-high > posterior-high (P<0.001). ③In the comparison of left and right coronal height, there was no statistical significance in the left and right coronal height of L1-S1 disc between male and female(P>0.05). ④The L1-S1 intervertebral spaces angle between male and female increased with the increase of vertebral body segments. ⑤The anterior and posterior diameters and transverse diameters of upper and lower of L1-S1 vertebral bodies endplates were height in males than in females(P<0.001).@*CONCLUSION@#The results suggest that gender differences should be considered in the design of adult lumbar disc prostheses. The anatomical parameters of the lumbar intervertebral disc varied with the increase of the vertebral body sequence, suggesting that different anatomical parameters of the intervertebral disc should be considered in the design of the artificial intervertebral disc, and the changes in the height of the sagittal position suggest that the design of the intervertebral disc should be wedge-shaped.

Comparison of alkaloids in Aconiti Kusnezoffii Radix, Aconiti Radix, and Aconiti Lateralis Radix Praeparata based on UHPLC-Q-Exactive Orbitrap MS/MS / 中国中药杂志

UHPLC-Q-Exactive Orbitrap MS/MS was used to systematically analyze and compare the alkaloids in Aconiti Kusnezoffii Radix, Aconiti Radix, and Aconiti Lateralis Radix Praeparata. After the samples were pretreated in the solid-phase extraction cartridges, 0.1% ammonium hydroxide(A)-acetonitrile(B) was used for gradient elution. The LC-MS method for characterization of alkaloids in the three herbal medicines was established in ESI positive ion mode to collect high resolution MS data of reference substances and samples. On the basis of the information of reference substance cracking behavior, retention time, accurate molecular mass, and related literature, a total of 155 alkaloids were identified in Aconiti Kusnezoffii Radix, Aconiti Radix, and Aconiti Lateralis Radix Prae-parata. Specifically, 130, 127, and 92 alkaloids were identified in Aconiti Kusnezoffii Radix, Aconiti Radix, and Aconiti Lateralis Radix Praeparata, respectively. Monoester alkaloids and amino-alcohol alkaloids were dominant in the three herbal medicines, and the alkaloids in Aconiti Kusnezoffii Radix and Aconiti Radix were similar. This paper can provide a reference for elucidating the pharmacological effects and clinical application differences of the three herbal medicines produced from plants of Aconitum.

A retrospective comparative study between robotic thyroidectomy through transoral vestibular approach and bilateral breast-axillary approach / 中华外科杂志

Objective: To compare the surgical outcome of robotic thyroidectomy through transoral approach and the bilateral breast-axillary approach. Methods: Retrospective analysis was made on the clinical data of patients who performed transoral robotic thyroidectomy (TORT group) or bilateral breast-axillary approach (BABA group) in the Department of Thyroid and Breast Surgery, the 960th Hospital of People's Liberation Army from July 2020 to May 2022. Both groups received lobectomy with lymph node dissection of the central region. A total of 100 cases were included in the study, including 48 cases in the TORT group and 52 cases in the BABA group. The propensity score matching method was used for 1∶1 matching of patients between the 2 groups, with a match tolerance of 0.03. There were 31 patients in each group successfully matched. In the TORT group, there were 5 males and 26 females, aged (33.2±7.9) years (range: 21 to 53 years). While there were 4 males and 27 females in the BABA group, aged (34.6±9.2) years (range: 19 to 58 years). The t test, Mann-Whitney U test, χ2 test or Fisher exact test were used to compare the clinical efficacy between the two groups. Results: All the patients successfully completed robotic thyroid surgery without conversion to open surgery. Compared with BABA group, the TORT group had longer operation time ((211.3±57.2) minutes vs. (126.2±37.8) minutes, t=6.915, P<0.01), shorter drainage tube retention time ((5.4±1.0) days vs. (6.4±1.2) days, t=-3.544, P=0.001), shorter total hospital stay ((6.6±1.2) days vs. (7.4±1.3) days, t=-2.353, P=0.022), and higher cosmetic score (9.46±0.25 vs. 9.27±0.26, t=2.925, P=0.005). There was no significant difference between the two groups in the number of lymph nodes dissection, metastasis in the central compartment, and the incidence of postoperative complications (all P>0.05). Conclusions: Compared with the bilateral breast-axillary approach, the transoral vestibular approach of robotic thyroidectomy is also safe and effective. It shows similar surgical results to the bilateral breast-axillary approach in strictly selected patients, but the postoperative recovery speed is much faster, and the hospital stay is shorter. Transoral robotic thyroidectomy is a more recommended surgical method for patients with high aesthetic demand.

GAO Wei-bin's clinical experience in treatment of neurogenic bladder with acupuncture / 中国针灸

The paper introduces GAO Wei-bin's clinical experience in acupuncture treatment for neurogenic bladder. In association with the etiology, the location and types of neurogenic bladder and in accordance with nerve anatomy and meridian differentiation, the acupoints are selected accurately in treatment. Four acupoint prescriptions are allocated. For frequent urination and urinary incontinence, the foot-motor-sensory area of scalp acupuncture, Shenshu (BL 23) and Huiyang (BL 35) are used. For all kinds of urine retention, especially the patients who are not suitable for acupuncture at the lumbar region, Zhongji (CV 3), Qugu (CV 2), Henggu (KI 11) and Dahe (KI 12) are selected. For all kinds of urine retention, Zhongliao (BL 33) and Ciliao (BL 32) are applicable. For the patients with both dysuria and urinary incontinence, Zhongliao (BL 33), Ciliao (BL 32) and Huiyang (BL 35) are chosen. In treatment of neurogenic bladder, both biao (root causes) and ben (primary symptoms) are considered, as well as the accompanying symptoms; and electroacupuncture is combined accordingly. During the delivery of acupuncture, the sites where the acupoints located are detected and palpated so as to rationally control the depth of needle insertion and the operation of reinforcing and reducing needling techniques.

Clinical features and long-term prognosis of diabetic patients with low or intermediate complexity coronary artery disease post percutaneous coronary intervention / 中华心血管病杂志

Objective: To investigate the clinical features and long-term prognostic factors of diabetic patients with low or intermediate complexity coronary artery disease (CAD) post percutaneous coronary intervention (PCI). Methods: This was a prospective, single-centre observational study. Consecutive diabetic patients with SYNTAX score (SS)≤32 undergoing PCI between January and December 2013 in Fuwai hospital were included in this analysis. The patients were divided into two groups based on SS, namely SS≤22 group and SS 23-32 group. Multivariate Cox regression analysis was performed to identify independent factors related to poor 5-year prognosis. The primary outcomes were cardiac death and recurrent myocardial infarction, the secondary outcomes were all cause death and revascularization. Results: Of the 3 899 patients included in the study, 2 888 were men (74.1%); mean age was 59.4±9.8 years. There were 3 450 patients in the SS≤22 group and 449 patients in the SS 23-32 group. Compared with SS≤22 group, the incidence of revascularization was higher in SS 23-32 group (18.9% (85/449) vs. 15.2% (524/3450), log-rank P=0.019). There was no significant difference in all-cause death, cardiac death and recurrent myocardial infarction between the two groups (log-rank P>0.05). Multivariate Cox regression analysis showed that age (HR=1.05, 95%CI 1.02-1.08, P<0.001), chronic obstructive pulmonary disease (HR=3.12, 95%CI 1.37-7.07, P=0.007) and creatinine clearance rate (CCr)<60 ml/min (HR=3.67, 95%CI 2.05-6.58, P<0.001) were independent risk factors for 5-year cardiac death, while left ventricular ejection fraction (HR=0.94, 95%CI 0.91-0.96, P<0.001) was a protective factor. Previous PCI (HR=2.04, 95%CI 1.38-3.00, P<0.001), blood glucose level≥11.1 mmol/L on admission (HR=2.49, 95%CI 1.32-4.70, P=0.005) and CCr<60 ml/min (HR=1.85, 95%CI 1.14-2.99, P=0.012) were independent risk factors for 5-year recurrent myocardial infarction. The SS of 23-32 was independently associated with risk of revascularization (HR=1.54, 95%CI 1.09-2.16, P=0.014), after adjusting for residual SS. Residual SS was not a risk factor for 5-year prognosis. Conclusions: In diabetic patients with low-or intermediate complexity CAD, SS 23-32 is associated with increased risk of 5-year revascularization; the clinical characteristics of the patients are associated with the long-term mortality and recurrent myocardial infarction, but not related to revascularization.
