ABSTRACT

OBJECTIVE@#To compare the long-term follow-up effect and complications of ceramic on ceramic (CoC) interface and ceramic on polyethyleneon ceramic (CoP) interface in primary total hip arthroplasty, and provide clinical evidence.@*METHODS@#Search PubMed, EMBase, the CoChrane Library databases, Web of science, Wanfang database, and CNKI from January 2000 to September 2021, screening and inclusion of randomized controlled trials (RCTs) comparing the long-term efficacy and complications of CoC interface and CoP interface in total hip arthroplasty. Literature screening, quality evaluation and data extraction were carried out according to the inclusion and exclusion criteria, using Review Manager 5.3 statistical software. The software was used to perform statistical analysis on joint function, revision, prosthesis fracture, abnormal joint noise, and prosthesis wear rate after CoC or CoP.@*RESULTS@#Seven RCTs studies were included, including 390 cases of hips with CoC artificial joints and 384 cases of hips with CoP artificial joints. The long-term joint function improvement of CoC and CoP artificial joints was similar and there was no significant differences, with an average difference was MD=0.63, 95%CI=(-1.81, 3.07), P=0.61. About the postoperative complications, CoC artificial joints have higher incidence rate of abnormal joint noise, with odds ratio (OR)=11.05, 95%CI=(2.04, 59.84), P=0.005. CoP artificial joints wear faster, with an average MD=-87.11, 95%CI=(-114.40, -59.82), P<0.000 1. There was no significant difference between the two groups in the replacement-related complications such as joint dislocation, prosthesis loosening, osteolysis, and the rate of prosthesis revision caused by various reasons.@*CONCLUSION@#The clinical function results and complications of CoC artificial joints are comparable to those of CoP artificial joints. Although CoP artificial joint prosthesis has a faster wear rate, it does not affect joint function and increase complications, and there is no abnormal joint noise. CoC is expensive and the long-term efficacy is equivalent to CoP. Clinicians should consider cost performance when choosing CoC.

ABSTRACT

ObjectiveTo observe the effects of modified Chaihu Shugansan(CHSG) and its disassembled formulas on angiotensin-converting enzyme 2 (ACE2)-angiotensin (Ⅰ-Ⅶ) [Ang (Ⅰ-Ⅶ)]-mitochondrial assembly receptor (MasR) axis in hyperlipidemic rats with myocardial ischemia and depression, and to explore the underlying mechanism of its prevention and treatment of myocardial ischemia and depression. MethodA total of 108 male SD rats were randomly divided into a normal group, a model group, a modified CHSG group (11.7 g·kg-1), a Quyu Huatan disassembled formula group (4.05 g·kg-1), a Shugan Xingqi disassembled formula group (3.15 g·kg-1), a Jianpi Yangxue disassembled formula group (4.5 g·kg-1), a fluoxetine group (0.001 8 g·kg-1), a trimetazidine group (0.005 4 g·kg-1), and a simvastatin group (0.001 8 g·kg-1), with 12 rats in each group. The hyperlipidemia model with myocardial ischemia and depression was induced with a high-fat diet combined with injection of isoproterenol (ISO) and chronic unpredictable mild stress (CUMS) in rats in the model group and groups with drug intervention for eight weeks. The rats in each group with drug intervention were treated correspondingly by gavage from the first day of modeling, while those in the normal group and the model group received the same amount of normal saline. The behavioral changes of rats in each group were observed by open field test and forced swimming test. Left ventricular fractional shortening (LVFS) and left ventricular ejection fraction (LVEF) were measured by echocardiography. The serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were detected by the enzyme-labeled apparatus. Hematoxylin-eosin (HE) staining was used to observe the histomorphological changes of the heart. The serum levels of angiotensin Ⅱ (AngⅡ), ACE2, and Ang(Ⅰ-Ⅶ) were detected by enzyme-linked immunosorbent assay (ELISA). The protein and mRNA expression of ACE2 and MasR in the hippocampus and the heart was detected by real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot. ResultCompared with the normal group, the model group showed reduced movement time, distance, and average speed in the central area of the open field (P<0.01), prolonged immobility time of rats in the forced swimming test (P<0.01), decreased LVFS and LVEF (P<0.01), inflammatory exudation and disorderly arranged fiber in heart tissues, elevated serum levels of TC, LDL-C, AngⅡ, ACE2 and Ang(Ⅰ-Ⅶ), diminished HDL-C (P<0.01), dwindled mRNA and protein expression of ACE2 in the hippocampus and the heart and MasR in the hippocampus, and up-regulated mRNA and protein expression of MasR in the heart (P<0.01). Compared with the model group, the modified CHSG group displayed increased movement time, distance, and average speed in the center area of the open field (P<0.01), shortened immobility time in the forced swimming test (P<0.01), increased LVFS and LVEF (P<0.01), relieved heart injury, reduced serum levels of TC, LDL-C, AngⅡ, ACE2, and Ang(Ⅰ-Ⅶ), elevated level of HDL-C (P<0.01), up-regulated mRNA and protein expression of ACE2 in the hippocampus and the heart and MasR in the hippocampus, and down-regulated mRNA and protein expression of MasR in the heart (P<0.01). Each disassembled formula could improve the above indexes to a certain extent (P<0.05, P<0.01), but the effect of the whole formula was optimal. ConclusionThe modified CHSG and its disassembled formulas have the effects of resisting depression, improving myocardial injury, and reducing blood lipid. Due to the synergistic effects of stasis-resolving/phlegm-eliminating drugs, liver-smoothing/Qi-moving drugs, and spleen-tonifying/blood-nourishing drugs in the formula, the modified CHSG is superior to each disassembled formula in efficacy. Its mechanism may be related to the activation of the ACE2-Ang (Ⅰ-Ⅶ)-MasR axis.

ABSTRACT

OBJECTIVE@#To observe the effect of acupuncture and moxibustion on the water content of stratum corneum (WCSC), expression of serum inflammatory factors and aquaporin 3 (AQP3) in skin, lung and rectum in guinea pigs with eczema of skin damp-heat accumulation, and to explore the possible mechanism of acupuncture and moxibustion for regulating skin barrier function.@*METHODS@#A total of 24 male albino guinea pigs were randomly divided into a blank group (n=6) and a modeling group (n=18). The guinea pigs in the modeling group were induced by 2,4-dinitrochlorobenzene (DNCB) to establish the eczema model of skin damp-heat accumulation. The guinea pigs with successful modeling were further randomly divided into a model group, a medication group and an acupuncture-moxibustion group, 6 guinea pigs in each group. The guinea pigs in the medication group were treated with loratadine tablets (0.8 mg/kg) by gavage, once a day for 7 days; the guinea pigs in the acupuncture-moxibustion group were treated with acupuncture at "Feishu" (BL 13), "Pishu" (BL 20), "Quchi" (LI 11), "Zusanli" (ST 36) and "Xuehai" (SP 10); at the same time, moxibustion was applied at "Feishu" (BL 13) and "Zusanli" (ST 36), moxibustion intervention for 10 min and needle retaining for 15 min at each acupoint, once a day for 7 days. The eczema area and severity index (EASI) score was evaluated before and After intervention, and WCSC and trans-epidermal water loss (TEWL) were measured by skin tester. After intervention, The HE staining was used to observe the changes of skin histomorphology in each group; ELISA was used to measure the contents of serum immunoglobulin E (IgE), interleukin (IL)-4 and IL-17; Western blot was used to measure the protein expression of AQP3 in skin, lung and rectum.@*RESULTS@#Before the intervention, compared with the blank group, the EASI scores and TEWL were increased in the remaining groups (P<0.01), and the WCSC was decreased (P<0.01). After the intervention, compared with the model group, the EASI scores and TEWL were decreased (P<0.05, P<0.01), and WCSC was increased (P<0.01) in the medication group and the acupuncture-moxibustion group. The epidermal structure in the blank group was complete and the fibers in the dermis were arranged orderly; in the model group, epidermal hyperkeratosis, proliferation of granular layer, spinous cell layer and basal layer, and disordered arrangement of dermal fibers and infiltration of inflammatory cells were observed. The morphological performance in the medication group and the acupuncture-moxibustion group was better than that in the model group. Compared with the blank group, the contents of serum IgE and IL-17 were increased (P<0.01), and the content of serum IL-4 and the protein expression of AQP3 in skin, lung and rectum were decreased in the model group (P<0.01, P<0.05). Compared with the model group, the contents of serum IgE and IL-17 were decreased and the contents of serum IL-4 were increased in the medication group and the acupuncture-moxibustion group (P<0.01), and the protein expression of AQP3 in skin, lung and rectum in the acupuncture- moxibustion group were increased (P<0.05). Compared with the medication group, the contents of serum IgE and IL-17 were increased (P<0.01), and the content of serum IL-4 was decreased (P<0.01) in the acupuncture-moxibustion group.@*CONCLUSION@#Acupuncture and moxibustion could improve the epidermal water metabolism and skin tissue morphology in guinea pigs with eczema of skin damp-heat accumulation. Its mechanism may be related to regulating inflammatory factors, up-regulating the expression of AQP3, and then repairing the skin barrier function.

ABSTRACT

Objective:To investigate the killing effect of radiation on echinococcus in vitro culture and its effect on the mRNA expression of growth arrest and DNA damage 45 alpha (Gadd45α) gene. Methods:Echinococcus from naturally infected sheep liver was cultured in vitro and divided into 7 groups. The echinococcus was irradiated with 6 MeV at doses of 0 (control), 20, 40, 60, 80, 100, and 120 Gy, respectively. The growth of echinococcus was observed under light microscope at 1, 3, 5 and 7 d after the radiation. The expression of Gadd45α mRNA in control, 20, 40 and 60 Gy groups of echinococcus was detected by RT-PCR technique at 7 d after the radiation. Results:The disintegration and exfoliation of echinococcus were observed under light microscope at 1, 3, 5 and 7 d after the radiation, and the death rate of echinococcus was positively correlated with the radiation dosages ( r = 0.81, P < 0.05). After the radiation at 7 d, compared with the control group (100.00 ± 0.00), the mRNA expression levels of Gadd45α in echinococcus of 20, 40, and 60 Gy groups were significantly increased (279.74 ± 80.08, 759.38 ± 160.98, 1 666.68 ± 316.36, P < 0.01), and it was positively correlated with the radiation dosages ( r = 0.93, P < 0.01). Conclusion:Radiation has a certain killing effect on echinococcus cultured in vitro, and there is a certain dose-effect relationship with the radiation dosages, and Gadd45α gene may be involved in the molecular mechanism of radiation-induced killing of echinococcus in vitro.

ABSTRACT

Based on the educational structure theory, the difference between mass education and elite education is probed at the macroscopic level to make it clear that the essence of Physician education and training program of excellence is elite education for occupational purposes; at the mi-croscopic level the orientation of English teaching for the class ofexcellent physicians is determined as English for occupational purposes. Moreover, the curriculum system of medical English is designed, and teaching materials associated with clinical medicine are selected, the language laboratory simulat-ing hospital scenes is constructed, and the transboundary team of teachers is built comprising university teachers and doctors in hospitals. At the level of individual, the competency model of English forexcellent physicianshas been developed, English competence requirements in medical industry being clearly established . In a word , the study of macrostructure points out the direction and target of English teaching for excellent physicians; the study of microstructure perfects the mode of English teaching forexcellent physicians;and the study of individual structure indicates the ultimate foothold of English education forexcellent physicians. Three aspects are integrated into an organic whole.

ABSTRACT

@#Objective To explore the establishment of a rat model of acute radiation-induced liver injury and sig-nificance of the dynamic changes of TGF-β1 expression.Methods Forty healthy 6-week old male SD rats were randomly divided into model group (n=30) and control group (n=10).The right liver of rats in the model group was given a single dose of 25 Gy 6 MV X-ray irradiation.Histopathological examination using HE staining and transmission electron microsco-py were conducted to observe the liver pathological changes in rats at 3, 5, and 10 days after irradiation, serum TGF-β1 was detected, and relevant indicators of liver function ( ALT, AST, ALP) were determined.Statistical analysis was per-formed using SPSS 17.0 software.Results At 3, 5 and 10 days after irradiation, early pathological changes in the liver cells were observed by electron microscopy, the expression of TGF-β1 was gradually increased with the time prolongation, and significant differences were found between the model group and the control group at different time points (P<0.05). The light microscopic observation of liver tissues did not show significant differences between the control group and model group.The liver ALT, AST, ALP at different time points did not show significant differences between the two groups ( P>0.05).Conclusion Electron microscopy can be used to evaluate the early changes of radiation-induced liver injury, pri-or to the alterations visible by routine light microscopy.TGF-β1 can be used to predict the degree of radiation-induced liver injury, and may be used as a sensitive serum cytokine in predicting the degree of radiation-induced acute liver injury.

ABSTRACT

Objective To compare the efficacy and side-effects of preoperative neoadjuvant uterine arterial chemoembolization and venous chemotherapy in treating cervical cancer in young female patients. Methods A total of 241 young females(≤35 years old) with cervical cancer were enrolled in this study. The clinical data were retrospectively analyzed. The patients were divided into group A (n=63) and group B (n=57). Patients in group A received preoperative neoadjuvant uterine arterial chemoembolization with subsequent surgery, while patients in group B were treated with preoperative neoadjuvant intravenous chemotherapy followed by surgery. The chemotherapy scheme included carboplatin (50 mg/m2) and gemcitabine (1 000 mg/m2). The short-term effect, the amount of blood loss during the surgery, pathological findings and the side-effects of the two groups were compared. The Kaplan-Meier method was used to calculate survival rate, and the log-rank test was used for survival difference analysis. Results The short-term response rate of group A was 90.5%, which was significantly higher than that of group B (71.9%), the difference between the two groups was statistically significant (χ2=7.5, P0.05). In both groups, the clinical stage, the pathological grade and the size (≥ 4 cm) of the tumor were the main factors that could influence the prognosis in young females with cervical cancer (P<0.05). Conclusion The short-term efficacy of preoperative uterine artery chemoembolization is better than that of preoperative intravenous chemotherapy for the treatment of cervical cancer in young female patients. Besides, this therapy carries mild side effect, and it can improve the 5-year progression-free survival rate, although the long-term survival rate has not been obviously improved.
