ABSTRACT

Objective:To evaluate the feasibility of indocyanine green fluorescence imaging technology applied in thyroid surgery to identify parathyroid gland.Methods:From Oct 2021 to May 2022, data of 42 patients undergoing thyroidectomy via gasless unilateral axillary approach in Zhejiang Provincial Hospital of Traditional Chinese Medicine were retrospectively analyzed. Cases using intraoperative fluorescence imaging technology(42 cases) were compared with conventional laparocopic approach.Results:The number of parathyroid glands dissected in the study group 1.57±0.61 was higher than that in the control group 0.56± 0.59 ( t=-5.472, P<0.05). The PTH value of the study group was (2.88±1.23)pmol/L on the first day after operation, which was higher than that of the control group (2.16±0.10)pmol/L ( t=-1.844, P<0.05). The blood parathyroid hormone value on the third day(3.22±1.31)pmol/L was higher than that of the control group (2.55±0.81) pmol/L ( t=-2.041, P<0.05). There were 2 cases of hypoparathyroidism in the study group, less than 5 cases in the control group, but there was no significant difference between the two groups( χ2=0.942, P>0.05). There was 1 case of hypocalcemia in the study group and 3 cases in the control group ( χ2=0.731, P>0.05). Conclusion:Using indocyanine green fluorescence imaging technology to identify parathyroid gland is feasible, simple, fast, safe and effective.

ABSTRACT

Objective:To investigate serum C-reactive protein (CRP) , procalcitonin (PCT) and neutrophil CD64 in predicting early infection after internal fixation of limb fractures.Methods:A total of 2 572 patients with limb fractures undergoing internal fixation in Taishun County People’s Hospital from January 2016 to December 2022 were enrolled. Postoperative infection occurred in 121 cases (infected group) and did not occur in 2 451 cases (uninfected group). Serum levels of PCT, CRP and CD64 were tested at admission and d1, d3, d5 and d7 after operation. Repeated measurement analysis of variance was used to compare the serum levels of PCT, CRP and CD64 at different time points between two groups, the receiver operating characteristic curve (ROC) was used to evaluate the predictive value of each index or in combination for early infection after internal fixation of limbs fractures.Results:The early infection rate after internal fixation was 4.70% (121/2 572). The levels of PCT, CRP and CD64 in the infection group began to rise after operation and decreased on d7; there were significant differences in PCT, CRP and CD64 levels between the two groups on d3, d5 and d7 after operation (PCT: Ftime=678.607, Fintergroup=2 218.323, Finteraction=653.150; CRP: Ftime=392.724, Fintergroup=1 812.502, FInteraction =379.577; CD64: Ftime=373.686, Fintergroup=4 817.438, Finteraction=528.353, all P< 0.001) . The area under the ROC curve of combined detection of PCT, CPR, and CD64 for predicting early infection was 0.856; the sensitivity and specificity of combined detection were 69.2% and 94.7%, respectively. The combined detection of three indicators showed better prediction values than PCT, CRP and CD64 alone ( Z=6.176, 3.838 and 2.431, P<0.01 or <0.05), and also better than combined detection of PCT and CRP ( Z=2.875, P=0.019). Conclusions:The combined detection of CD64, PCT and CRP is of value in prediction of postoperative infection after internal fixation of limb fractures, which is worthy of clinical application.

ABSTRACT

Objective:To explore the methods of standardized residency training for internal medicine residents in the post-epidemic era, and to provide theoretical basis for improving and optimizing the standardized residency training.Methods:A total of 228 resident physicians from Batch 2017 to Batch 2019 were recruited, and a questionnaire survey was conducted to investigate their basic information, their attitudes and actions in facing the epidemic and the epidemic impact on the occupational planning and rotation plan. Original data of this study were exported through the questionnaire platform "Questionnaire Network", sorted out by Microsoft Excel, and plotted and analyzed by Origin software.Results:Residents of our hospital, socialized medical residents, other unit sponsor residents and combined professional masters willing to go to Hubei for medical support accounted for 100% (30 people), 86% (6 people), 84% (80 people) and 77% (72 people) respectively. Almost all of the residents were willing to learn the knowledge of COVID-19 and to educate the public (99%-100%). Eighty percent (24 people) of the residents of our hospital participated in anti-epidemic, while the proportion of other unit sponsor residents, socialized medical residents and combined professional masters were 46% (44 people), 14% (1 people) and 12% (11 people), respectively. Additionally, 97% (29 people) of our hospital residents, 89% (85 people) of other unit sponsor residents, 86% (6 people) of the socialized medical residents, and 82% (76 people) of the combined professional masters would still like to engage in the clinical work in the future. What's more, the resident physicians who thought that phylaxiology, epidemiology, general practice medicine, traditional Chinese medicine and critical care medicine should be strengthened to train accounted for 98% (221 people), 98% (221 people), 90% (203 people), 70% (158 people) and 60% (135 people) respectively.Conclusion:Most resident physicians have strong awareness and active actions in fighting against the epidemic. In the future, the standardized residency training of physicians should further strengthen the training of phylaxiology, epidemiology, general practice medicine, traditional Chinese medicine and critical care medicine.

ABSTRACT

Objective:To explore the influencing and prognosis factors of emphysematous urinary tract infection (EUTI).Methods:The baseline clinical data of the patients admitted to Shandong University Qilu Hospital (Qingdao) from December 2013 to June 2020 and diagnosed with EUTI were analyzed retrospectively. The patients with non-EUTI (NEUTI) during the same period were selected as the control group. The baseline characteristics between the two groups were compared. Logistic regression analysis method was used to analyze the influencing factors of EUTI.Results:(1) 24 EUTI patients and 53 NEUTI patients were included in the present study. Compared with the NEUTI group, the hemoglobin level was lower ( t=-5.245, P<0.001) and the levels of blood urine nitrogen ( Z=-4.361, P<0.001), serum creatinine (Scr, Z=-4.543, P<0.001), blood glucose ( Z=-2.608, P=0.009), and triacylglycerol ( Z=-2.408, P=0.016) were higher in the EUTI group. The proportions of diabetes mellitus ( χ2=13.453, P<0.001) and chronic kidney disease ( χ2=17.936, P<0.001) in the EUTI group were higher than those in the NEUTI group. Increasing Scr was the risk factor of EUTI in patients with urinary tract infection ( OR=1.011, 95% CI 1.001-1.020, P=0.025). (2) Escherichia coli ( E.coli, 14 cases, 58.3%) was the most common causative organism. The other causative organisms included Klebsiella pneumoniae (2 cases, 8.3%), Enterococcus faecium (1 case, 4.2%), Pantoea (1 case, 4.2%), and mixed bacteria of E.coli and Enterococcus faecium (1 case, 4.2%). Ten cases of E.coli were extended-spectrum β-lactamases (ESBL)-positive. (3) Of the 24 patients with EUTI, 4 patients had adverse outcomes. The length of stay ( Z=-2.457, P=0.014), blood urea nitrogen ( t=2.432, P=0.024), shock ( P=0.002), autoimmune disease ( P=0.022), and white blood cell count ( Z=-2.091, P=0.036) were statistically different between good prognosis group ( n=20) and poor prognosis group ( n=4). However, logistic regression analysis results showed that neither was the influencing factor of poor prognosis of EUTI. Conclusions:The elevated Scr level is the independent influencing factor of EUTI among urinary infection patients. E.coli is the most common pathogenic bacteria, and ESBL-positive bacteria are common.

ABSTRACT

OBJECTIVE@#To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction.@*METHODS@#Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period.@*RESULTS@#After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min•1.73 m, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min•1.73 m, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min•1.73 m per year.@*CONCLUSION@#Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).

ABSTRACT

Background: The suppression of cancer cell growth and invasion has become a challenging clinical issue. In this study, we used nanotechnology to create a new drug delivery system to enhance the efficacy of existing drugs. We developed layered double hydroxide by combing Au nanosol (LDH@Au) and characterized the compound to prove its function as a drug delivery agent. The anti-cancer drug Doxorubicin was loaded into the new drug carrier to assess its quality. We used a combination of apoptosis assays, cell cycle assays, tissue distribution studies, cell endocytosis, transwell invasion assays, and immunoblotting to evaluate the characteristics of LDH@Au as a drug delivery system. Results: Our results show that the LDH@Au-Dox treatment significantly increased cancer cell apoptosis and inhibited cell invasion compared to the control Dox group. Additionally, our data indicate that LDH@Au-Dox has a better target efficiency at the tumor site and improved the following: cellular uptake, anti-angiogenesis action, changes in the cell cycle, and increased caspase pathway activation. Conclusions: Our findings suggest the nano drug is a promising anti-cancer agent and has potential clinical applications.

ABSTRACT

Objective The extracorporeal cardiac shock wave therapy ( CSWT ) can promote angiogenesis in ischemic myo-cardium and improve myocardial perfusion , but its mechanisms remain to be clarified .This study aimed to explore the effects of CSWT on the endothelial progenitor cells (EPCs), vascular endothe-lial growth factor ( VEGF) and Interleukin-8 ( IL-8) as well as its re-lieving effect on angina pectoris in patients with coronary heart dis-ease. Methods After Dobutamine stress echocardiography ( DSE) and 99 mTc-MIBI myocardial perfusion imaging (MPI) at rest and un-der stress, 25 patients with coronary heart disease underwent 9 three-month cycles of CSWT .Before and after the treatment , we obtained the results of 6-min walk test, NYHA cardiac function grades , CCS angina pectoris classes, Seattle Angina Questionnaire (SAQ) scores, doses of nitroglycerin administered , left ventricular diastolic di-ameter ( LVDD) , and left ventricular ejection fraction ( LVEF) .We evaluated myocardial perfusion and myocardial contractile function using MPI and the peak systolic strain rate (PSSR) at rest and under stress, respectively. Results After CSWT, the numbers of EPCs and EPC-CFUs cultured in vitro were significantly increased as compared with the baseline (34.52±6.58 vs 19.56±4.28, P0.05).The PSSR showed no significant changes at rest (1.21±0.62 vs 1.04±0.43, P>0.05) but remark-ably increased under stress after CSWT (2.02±1.00 vs 1.35±0.66, P<0.01). Conclusion CSWT can up-regulate the expressions of VEGF and IL-8 and improve the function of EPCs in the peripheral blood , and thus plays an important role in relieving the symptoms of angina pectoris , promoting cardiac function and enhancing exercise tolerance in patients with coronary heart disease .

ABSTRACT

Objective To investigate the effect of different time of hypoxia reoxygenation (HR) on cell autophagy and cell viability.Methods According to the different reoxygenation time,H9C2 cells were divided into five groups:normal control group (group A),hypoxia group (group B),reoxygen 2h group (group C),reoxygen 12h group (group D) and reoxygen 24h group (group E).The expression of LC3 Ⅱ/LC3 Ⅰ in each groups was detected by Western Blot,and the activity of myocardial cells was detected by MlT.Results MlT results showed that the viability of the myocardial cells after hypoxia 2h/reoxygenation 2h was significantly lower than that in the normal control group (P<0.05).The ratio ofLC3 Ⅱ/LC3 Ⅰ of the cells in group B (hypoxia group),group C (reoxygen 2h group),group D (reoxygen 12h group),group E (reoxygen 24h group) was significantly higher than that of group A (normal control group) (P<0.05).Among them,the ratio of LC3 Ⅱ/LC3 Ⅰ of the cells in group C and D were significantly higher than that of group B (P<0.05),paticlularly the group D was the highest (P<0.05).The activity of myocardial cells in group D was the lowest among all groups.Conclusion Culturing in the three gas incubator can obviously decrease the viability of H9C2cells.Hypoxia can activate autophagy,and autophagy increases significantly after reoxygenation.Autophagy may be activated most obviously at 12 hours and decrease to the level of hypoxia group at 24 hours.Cells can be damaged by hypoxia,and further increase of cellular damage may occur after oxygen inhalation.At 12 hours,the cell viability is the lowest,and the cell viability may be improved at 24h.

ABSTRACT

Objective: To observe the effect of extracorporeal shock wave therapy (ESWT) on proliferation, cell cycle and intercellular adhesion molecule-1 (ICAM-1) expression in human umbilical vein endothelial cells (HUVECs). Methods: HUVECs were culturedin vitro at the concentration of (1×105/ml) and the cells were divided into 2 sets of groups:CSWT group, the cells were treated by different energy of (0.03, 0.09, 0.18, 0.24) mJ/mm2 respectively and corresponding Control group, in which the cells had no CSWT. HUVEC proliferation was detected by CCK colorimetric method, cell cycle was measured by lfow cytometry, mRNA and protein expressions of ICAM-1 were examined by RT-PCR and Western blot analysis respectively. Results: Compared with Control group, (0.09 mJ/mm2) CSWT group had promoted HUVECs proliferation,P0.05; (0.09 mJ/mm2) CSWT group showed decreased proportion of G0/G1 stage and increased S and G2/M stages, allP0.05. Compared with Control group, (0.09 mJ/mm2 ) and (0.03mJ/mm2) CSWT groups showed increased mRNA expression of ICAM-1 (9.27±0.95) vs (1.02±0.27),P<0.001 and (7.08±0.60) vs (1.02±0.27),P<0.01; (0.09 mJ /mm2) CSWT group had elevated protein expression of ICAM-1,P<0.05. Conclusion: ESWT especially at (0.09 mJ/mm2) may accelerate cell cycle transition from G0/G1 stage to S and G2/M stages, promote HUVECs proliferation and increase ICAM-1 expression which may play important roles in ESWT facilitated angiogenesis in vitro.

ABSTRACT

Objective Extracorporeal shock wave therapy ( ESWT ) can promote angiogenesis and collateral circulation es-tablishment by introducing shock waves to ischemia myocardium , however , the specific mechanisms remain unclearly .The study aimed to explore the effects of 0.09mJ/mm2 shock wave treatment on human umbilical vein endothelial cell (HUVEC) proliferation, vascular endothelial growth factor (VEGF) and Interleukin-8 (IL-8) expressions. Methods There were an experimental group and a control group in the experiment .The tubes of the experiment group were set in shock wave devices without the treatment of shock waves .As for the experiment group, 0, 0.03, 0.09, 0.18, 0.24 mJ/mm2 shock waves were introduced , followed by the addition of CCK8 solution and the measurement of A value at the wavelength of 450nm by microplate reader .The HUVEC cell lines were performed 0.09 mJ/mm2 ultrasonic shock energy , CCK8 colorimetric method were utilized to detect the HUVEC proliferation , real time PCR and flow cytometry were applied to detect the expressions of VEGF and IL-8 mRNA respectively . Results ① CCK8 colorimetric method revealed that 0.09 mJ/mm2 shock energy markedly promoted the HU-VEC proliferation compared with the control group , with A450 value comparison (0.70 ±0.04 vs 0.54 ±0.09, P0.05 ).②RT-PCR showed that the 0.09 mJ/mm2 energy significantly enhanced the expressions of VEGF and IL-8 mRNA compared with the control group (7.93 ±0.90 vs 1.07 ±0.40, 7.34 ±1.67 vs 1.00 ±0.09, P<0.001).③Flow Cytometry showed that the expressions of VEGF and IL-8 mRNA significantly increased after 0.09 mJ/mm2 ESWT compared with the control group (39.89 ±4.79 vs 20.98 ±3.30, 31.33 ± 5.61 vs 22.60 ±3.76, P<0.05). Conclusion Low-energy ESWs can surely promote HUVEC proliferation and increase the expres-sions of VEGF and IL-8, and the up-regulation of VEGF and IL-8 may play an important role in the promotion of angiogenesis by ESWT .

ABSTRACT

The long-term effects of repeated maternal separation (MS) during early postnatal life on reelin expression in the hippocampus of developing rats were investigated in the present study. MS was carried out by separating Wistar rat pups singly from their mothers for 3 h a day during postnatal days (PND) 2–14. Reelin mRNA and protein levels in the hippocampus were determined using qRT-PCR and Western blotting, at PND 22, PND 60 and PND 90. MS resulted in the loss of body weight in the developing rats, and reelin mRNA and protein levels in the hippocampus generally were down-regulated over the developing period, but the reelin mRNA and protein levels in the hippocampus of 90-day-old male rats were up-regulated. These findings suggest that the long-term effects of MS on the expression levels of hippocampal reelin mRNA and protein depends on the age at which the stressed rats’ brains were collected; reelin had important implications for the maternal-neonate interaction needed for normal brain development. In conclusion, repeated MS occurring during early postnatal life may cause the alterations of hippocampal reelin expression with the increasing age of developing rats.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of hydrogen sulfide (H2S) on H2O2-stimulated primary neonatal rat cardiomyocytes and related mechanism.</p><p><b>METHODS</b>Primary neonatal rat cardiomyocytes were treated with various concentrations of H2O2 (10, 100, 1000 µmol/L) for 24 h to establish the oxidative stress-induced cell injury model after 3 days' conventional culture. In addition, different concentrations of NaHS (1, 10, 100 µmol/L) were added to cardiomyocytes in the absence and presence of 100 µmol/L H2O2 for 24 h. The viability of cardiomyocytes was measured by MTT assay. The SOD vitality was measured by xanthine oxidase method and MDA content was determined by thiobarbituric acid colorimetric method. LDH activity was measured by chemical colorimetric method. The percentage of apoptotic cells was assessed by flow cytometry (FCM). The mitochondrial membrane potential (MMP) was analyzed by rhodamine 123 (Rh123) staining and photofluorography. The level of reactive oxygen species (ROS) in cardiomyocytes was measured by DCFH-DA staining and photofluorography.</p><p><b>RESULTS</b>Cell viability and SOD vitality were significantly reduced while MDA content and LDH activity were significantly increased with increasing H2O2 concentrations. These effects could be partly reduced by cotreatment with H2O2 in a concentration-dependent manner (all P < 0.05). Compared with control group, the DCF fluorescence intensity significantly increased in the 100 µmol/L H2O2 group (P = 0.003), which could be attenuated by NaHS in a dose-dependent manner. Compared with control group, the MMP significantly decreased in the 100 µmol/L H2O2 group (P = 0.000), which could be partly reversed by cotreatment with NaHS in a dose-dependent manner. Moreover, H2O2 treatment also significantly reduced 100 µmol/L H2O2 induced apoptosis in a dose-dependent manner.</p><p><b>CONCLUSION</b>H2S protects primary neonatal rat cardiomyocytes against H2O2-induced oxidative stress injury through inhibition of H2O2 induced overproduction of ROS, dissipation of MMP and apoptosis.</p>

ABSTRACT

Objective To investigate the mutations of CLCNKB gene in a family with classic Bartter syndrome. Methods Genetic DNA was extracted from peripheral blood leucocytes of family members.The coding exons and intron exon junctions of CLCNKB gene were amplyfied by PCR and sequenced directly.Fifty unrelated healthy subjects were selected to exclude the possibility of polymorphism. Results A heterozygous(missense)mutation(482T>G,L161R)was detected in the exon 4 of patients.The hetemzygous mutation(L161R)was found in the mother,while no mutation was found in the father of this family.L161R had not been reported and was a novel mutation when referring to literatures and human genomic database home and abroad.Conclusion A new CLCNKB gene mutation(L161R)is identified for the first time.

ABSTRACT

Objective To investigate the renoprective effect and its possible mechanism of Niaoduqing on the adriamycin(ADR)-induced nephropathy rats. Methods Forty eight male Sprague-Dawley rats were randomly divided into normal control(n=12), ADR-induced nephropathy(model, n = 12), Benazepril-treated ADR nephropathy(Benazepril, n=12)and Niaoduqing-treated ADR nephropathy(Niaoduqing, n =12)groups. The rat nephropathy model was established by adriamycin injection and unilateral nephrectomy. The rats were sacrifficed per batch at the 4th and 8th weekend.The pathological change of nephridial tissue, the 24-hour urinary protein excretion and renal function were examined. Immunohistochemistry was used to meassure the expression of fibronection(FN), collagenⅣ(COLⅣ), osteopontin(OPN). Results The 24-hour urinary protein excretion, BUN, Scr, triglyeride(TG), cholesterol(Cho)in model group were significantly higher than those in normal group(P<0.01), as well as more server glomerulosclerosis in kidney were observed in model group than those in control group(P<0.01), while the albumin(Alb)was lower (P<0.01). Compared with model group, the 24-hour urinary protein excretion, BUN, Scr, TG, Cho were significantly reduced and renal glomerulosclerosis was improved in Niaoduqing group(P< 0.01), while the Alb was higher(P<0.01). Conclusion Niaoduqing palys an important role in the prevention and treatment for nephropathy.
