ABSTRACT
Objective: To observe the association between clinical phenotypes of hypertrophic cardiomyopathy (HCM) patients and a rare calcium channel and regulatory gene variation (Ca2+ gene variation) and to compare clinical phenotypes of HCM patients with Ca2+ gene variation, a single sarcomere gene variation and without gene variation and to explore the influence of rare Ca2+ gene variation on the clinical phenotypes of HCM. Methods: Eight hundred forty-two non-related adult HCM patients diagnosed for the first time in Xijing Hospital from 2013 to 2019 were enrolled in this study. All patients underwent exon analyses of 96 hereditary cardiac disease-related genes. Patients with diabetes mellitus, coronary artery disease, post alcohol septal ablation or septal myectomy, and patients who carried sarcomere gene variation of uncertain significance or carried>1 sarcomere gene variation or carried>1 Ca2+ gene variation, with HCM pseudophenotype or carrier of ion channel gene variations other than Ca2+ based on the genetic test results were excluded. Patients were divided into gene negative group (no sarcomere or Ca2+ gene variants), sarcomere gene variation group (only 1 sarcomere gene variant) and Ca2+ gene variant group (only 1 Ca2+ gene variant). Baseline data, echocardiography and electrocardiogram data were collected for analysis. Results: A total of 346 patients were enrolled, including 170 patients without gene variation (gene negative group), 154 patients with a single sarcomere gene variation (sarcomere gene variation group) and 22 patients with a single rare Ca2+ gene variation (Ca2+ gene variation group). Compared with gene negative group, patients in Ca2+ gene variation group had higher blood pressure and higher percentage of family history of HCM and sudden cardiac death (P<0.05); echocardiographic results showed that patients in Ca2+ gene variation group had thicker ventricular septum ((23.5±5.8) mm vs. (22.3±5.7) mm, P<0.05); electrocardiographic results showed that patients in Ca2+ gene variation group had prolonged QT interval ((416.6±23.1) ms vs. (400.6±47.2) ms, P<0.05) and higher RV5+SV1 ((4.51±2.26) mv vs. (3.50±1.65) mv, P<0.05). Compared with sarcomere gene variation group, patients in Ca2+ gene variation group had later onset age and higher blood pressure (P<0.05); echocardiographic results showed that there was no significant difference in ventricular septal thickness between two groups; patients in Ca2+ gene variation group had lower percentage of left ventricular outflow tract pressure gradient>30 mmHg (1 mmHg=0.133 kPa, 22.8% vs. 48.1%, P<0.05) and the lower early diastolic peak velocity of the mitral valve inflow/early diastolic peak velocity of the mitral valve annulus (E/e') ratio ((13.0±2.5) vs. (15.9±4.2), P<0.05); patients in Ca2+ gene variation group had prolonged QT interval ((416.6±23.1) ms vs. (399.0±43.0) ms, P<0.05) and lower percentage of ST segment depression (9.1% vs. 40.3%, P<0.05). Conclusion: Compared with gene negative group, the clinical phenotype of HCM is more severe in patients with rare Ca2+ gene variation; compared with patients with sarcomere gene variation, the clinical phenotype of HCM is milder in patients with rare Ca2+ gene variation.

Objective:To investigate the clinical efficacy of liraglutide combined with metformin in the treatment of type 2 diabetes mellitus in overweight or obese patients.Methods:The clinical data of 120 overweight or obese patients with type 2 diabetes mellitus admitted to Bayannur Hospital from January 2020 to June 2021 was retrospectively analyzed. They were divided into study and control groups ( n = 60/group) according to different treatments. The study group was treated with liraglutide combined with metformin, and the control group was treated with metformin alone. All patients were treated for 12 weeks. Clinical efficacy was compared between the two groups. Results:After treatment, body mass, body mass index, fasting blood glucose, 2-hour postprandial blood glucose, glycated hemoglobin, total cholesterol, triglyceride, low-density lipoprotein cholesterol, visceral fat area, and insulin resistance index in the study group were (71.51 ± 10.12) kg, (25.98 ± 2.63) kg/m 2, (6.09 ± 0.99) mmol/L, (9.08 ± 2.39) mmol/L, (6.75 ± 1.13)%, (4.43 ± 0.88) mmol/L, (1.76 ± 0.68) mmol/L, (2.29 ± 0.90) mmol/L, (108.21 ± 26.46) cm 2 and (3.57 ± 1.45), respectively, which were significantly lower than (75.57 ± 7.11) kg, (27.91 ± 2.46) kg/m 2, (7.02 ± 0.95) mmol/L, (11.26 ± 2.86) mmol/L, (7.28 ± 1.04)%, (5.24 ± 1.11) mmol/L, (2.19 ± 0.70) mmol/L, (2.86 ± 0.97) mmol/L, (118.32 ± 28.63) cm 2, and (4.28 ± 2.07) respectively in the control group ( t = 2.54, 4.15, 5.23, 4.53, 2.66, 4.45, 3.43, 3.39, 2.01, 2.19, all P < 0.05). High-density lipoprotein cholesterol in the study group was significantly higher than that in the control group [(1.55 ± 0.28) mmol/L vs. (1.20 ± 0.32) mmol/L, t = -6.38, P < 0.05]. The grade of nonalcoholic fatty liver disease in the study group was significantly superior to that in the control group ( Z =-2.16, P < 0.05). Conclusion:Liraglutide combined with metformin can effectively improve blood glucose and lipid levels, and reduce insulin resistance, body weight, visceral adipose tissue and liver hepatocellular fatty deposits in overweight or obese patients with type 2 diabetes mellitus.
ABSTRACT
In the outbreak of COVID-19,triage procedures based on epidemiology were implemented in a local hospital in Changsha to control the transmission of SARS-CoV-2 and avoid healthcare-associated infection.This re-trospective study analyzed the data collected during the triage period and found that COVID-19 patients were en-riched 7 folds into the Section A designated for patients with obvious epidemiological history.On the other side,nearly triple amounts of visits were received at the Section B for patients without obvious epidemiological history.8 COVID-19 cases were spotted out of 247 suspected patients.More than 50％of the suspected patients were submi-tted to multiple rounds of nucleic acid analysis for SARS-CoV-2 infection.Of the 239 patients who were diagnosed as negative of the virus infection,188 were successfully revisited and none was reported as COVID-19 case.Of the 8 COVID-19 patients,3 were confirmed only after multiple rounds of nucleic acid analysis.Besides comorbidities,delayed sharing of epidemiological history added complexity to the diagnosis in practice.The triaging experience and strategy will be helpful for the control of infectious diseases in the future.
ABSTRACT
The development of chemoresistance which results in a poor prognosis often renders current treatments for colorectal cancer(CRC).In this study,we identified reduced microvessel density(MVD)and vascular immaturity resulting from endothelial apoptosis as therapeutic targets for overcoming chemoresistance.We focused on the effect of metformin on MVD,vascular maturity,and endothelial apoptosis of CRCs with a non-angiogenic phenotype,and further investigated its effect in overcoming chemoresistance.In situ transplanted cancer models were established to compare MVD,endothelial apoptosis and vascular maturity,and function in tumors from metformin-and vehicle-treated mice.An in vitro co-culture system was used to observe the effects of metformin on tumor cell-induced endothelial apoptosis.Transcriptome sequencing was performed for genetic screening.Non-angiogenic CRC developed inde-pendently of angiogenesis and was characterized by vascular leakage,immaturity,reduced MVD,and non-hypoxia.This phenomenon had also been observed in human CRC.Furthermore,non-angiogenic CRCs showed a worse response to chemotherapeutic drugs in vivo than in vitro.By suppressing endo-thelial apoptosis,metformin sensitized non-angiogenic CRCs to chemo-drugs via elevation of MVD and improvement of vascular maturity.Further results showed that endothelial apoptosis was induced by tumor cells via activation of caspase signaling,which was abrogated by metformin administration.These findings provide pre-clinical evidence for the involvement of endothelial apoptosis and subsequent vascular immaturity in the chemoresistance of non-angiogenic CRC.By suppressing endothelial apoptosis,metformin restores vascular maturity and function and sensitizes CRC to chemotherapeutic drugs via a vascular mechanism.
ABSTRACT
Objective:To investigate the effect of absorbable material internal fixation in the treatment of phalanx fracture and its effect on the complications related to hypersensitive C-reactive protein (hs-CRP), interleukin-10 (IL-10), adrenocorticotropic hormone (ACTH) and foreign body reaction.Methods:The clinical data of 98 patients with phalangeal fracture in Huishan District People′s Hospital of Wuxi City from January 2018 to January 2020 were divided into absorbable group (49 cases, treated with absorbable material internal fixation) and microplate group (49 cases, treated with minimally invasive plate internal fixation). The rates of excellent and good treatment, operation conditions, serum inflammatory stress response indexes levels before and 1 d and 1 week after surgery were compared, and recovery at 3 and 6 months after surgery, the incidence of complications and the degree of treatment satisfaction were counted.Results:The rates of excellent and good treatmentin the absorbable group were higher than that in the micro plate group: 95.92%(47/49) vs. 81.63%(40/49), χ2 = 5.02, P<0.05. The duration of operation in the absorbable group was longer than that in the microplate group: (43.28 ± 12.18) min vs. (31.29 ± 11.69) min; and the duration of hospital stay, fracture healing time and recovery time were shorter than those in the microplate group: (4.09 ± 1.18) d vs. (6.89 ± 2.12) d, (4.35 ± 1.05) weeks vs. (5.69 ± 1.38) weeks, (4.89 ± 1.10) d vs. (6.20 ± 2.01) d; the differences were statistically significant ( P<0.05). The levels of serum hs-CRP, IL-10 and ACTH in absorbable group were lower than those in microplate group at 1 d and 1 week after surgery ( P<0.05). At 3 and 6 months after surgery, the range of motion of metacarpophalangeal joint in the absorbable group was greater than that in the microplate group, and the loss of grip strength of the healthy side was less than that in the microplate group ( P<0.05). The incidence of complications in absorbable group was lower than that in microplate group: 6.12%(3/49) vs. 20.41%(10/49), χ2 = 4.35, P<0.05. Conclusions:The absorbable material internal fixation can achieve good results in the treatment of phalanx fracture, the postoperative recovery is fast, the incidence of complications is lower.
ABSTRACT
【Objective】 To investigate our experience in the diagnosis and treatment of acute graft-versus-host disease (aGVHD) after liver transplantation in surgical ICU. 【Methods】 We retrospectively analyzed the general data, clinical manifestation, diagnosis, and treatment strategies of five patients with aGVHD after liver transplantation in The First Affiliated Hospital of Xi’an Jiaotong University from January 2000 to December 2019. 【Results】 The incidence rate of aGVHD was 5/850 (5.88 ‰), and all the five patients were male and aged 40-64 years (mean age 56 years). Diabetes, hepatocellular carcinoma, liver transplantation, transcatheter arterial chemoembolization (TACE), and high concentration of immune agents were the main risk factors associated with the development of aGVHD. The average time from surgery until clinical symptom of aGVHD was 15 to 32 days. In our patients with aGVHD, the most common symptom was fever (5/5), followed by skin rash (5/5), pancytopenia (5/5), diarrhea (3/5), and secondary pulmonary infection (3/5). However, liver functions were not remarkable affected. Diagnostic criteria for aGVHD in our center include acute onset, risk factors, typical clinical manifestation, and histopathology after exclusion of differential diseases. Our treatment strategies include high-dose methylprednisolone, stopping/reducing current immunosuppressive protocol, and antilymphocytic agents as second-line treatment. Empirical antibiotics and antifungal agents play a vital part in infections after transplantation. Hematopoietic cytokine was administered to treat pancytopenia. Patients also received supportive therapy, such as isolation and nutritional support, with the goal of benefiting the entire condition. Despite intensive treatment, two of five patients (40%) with aGVHD died due to sepsis and multiorgan failure. One case (20%) died of intracranial hemorrhage and one case (20%) died of tuberculosis. Only one case (20%) stayed alive after 1-year follow-up without complications. 【Conclusion】 The diagnosis of aGVHD relies on clinical suspicion and is confirmed by skin pathology. The patients with aGVHD had early onset (38.5 ℃), large rash range (>50%), complication of sepsis, and poor response to hematopoietic cytokine therapy indicate poor prognosis. Intensive treatment should be started immediately after aGVHD diagnosis. In conclusion, we strongly suggest an early identification, diagnosis, and vigorous treatment strategy, which is the key to improving the prognosis of aGVHD.
ABSTRACT
Background/Aims@#Stigma related with antidepressants is prevalent in patients with functional dyspepsia. It affects medication compliance and efficacy.Herbal medicine acquired a deep-rooted cultural identity in relieving dyspeptic symptoms in Asians. The research was designed to compare the effectiveness of Zhizhu Kuanzhong capsules (ZZKZ) versus doxepin hydrochloride (doxepin) on alleviating stigma and medication nonadherence among patients with refractory FD (rFD). @*Methods@#Patients with rFD from February 2021 to February 2022 were randomly allocated to receive either doxepin (n = 56) or ZZKZ (n = 57) combined with omeprazole for 4 weeks. Medication possession ratio (MPR), the disease- and medication-associated stigma were analyzed. The scales were utilized to assess dyspeptic symptoms (Leeds Dyspepsia Questionnaire) and psychological conditions (Generalized Anxiety Disorder Questionnaire and Patient Health Questionnaire). @*Results@#The MPR values for ZZKZ were significantly higher than those for doxepin (P < 0.001). The stigma scores decreased in ZZKZ group while increased in doxepin group compared to baseline after treatment. The proportion of patients showing ZZKZ-associated stigma was significantly lower than doxepin-associated stigma (P < 0.001). The MPR values were negatively correlated with posttreatment stigma scores in both groups (P < 0.001). Dyspeptic symptoms and psychological condition were improved in both groups after treatment, with no significant difference on post-treatment Leeds Dyspepsia Questionnaire, Generalized Anxiety Disorder Questionnaire, or Patient Health Questionnaire scores between 2 groups. @*Conclusion@#ZZKZ is superior to doxepin in alleviating stigma and medication non-adherence, with comparable efficacy in improving dyspeptic symptoms and psychological condition of patients with rFD.
ABSTRACT
There are more than 60 million alcoholic liver disease (ALD) patients in China, which has become a public health problem that cannot be ignored. Moreover, the social problem of "alcohol culture" is still hardly to solve, so that safe and effective prevention and treatment for ALD are in urgent need clinically. Previous studies on ALD have focused on the direct damaging effects of alcohol and its toxic metabolites, while recent studies have shown that the pathogenesis of ALD also include alcohol metabolic reprogramming and endogenous metabolites disorder. Although the endogenous metabolites have no direct toxicity, its long-term effect should not be ignored. These endogenous metabolites could change epigenetic modifications, cause widespread and persistent abnormal gene expression and signal pathway activation abnormally to promote metabolic reprogramming and stamp it as "metabolic memory", which manifest pathological changes and promote ALD, especially liver fibrosis/cirrhosis and liver cancer. Based on this, the article reviews the important epigenetic modifications caused by related metabolites in ALD and their associated effects. The role of traditional Chinese medicine (TCM) and its active ingredients in regulating epigenetics was also analyzed. The results suggest that regulation of epigenetics and alteration of "metabolic memory" may be a novel mechanism of TCM in the prevention and treatment of ALD.
ABSTRACT
Extracellular vesicles (EVs) are an important type of active microvesicles. EVs encapsulate and transfer functional substances such as miRNAs, transcription factors and proteins, which are important vectors for cell communication and organ dialogue. In recent years, studies have shown that quite a number of Chinese medicinal herbs have the pharmacological effect of regulating EVs, and play a unique trans-organ and remote role in the treatment of diseases. Some Chinese medicinal herbs also contain plant-derived EVs themselves, which can be directly involved in the treatment of diseases. As one of the core theories of raditional Chinese medicines (TCM), Qi plays a variety of important roles in the physiological and pathological processes of human body and pharmacology. However, the scientific connotation of Qi′s role and the potential material carrier are still unclear. The latest research suggests that the effect of EVs is potentially related to that of Qi. Therefore, this paper reviews the effect of Qi nourishing Chinese medicinal herbs in regulating EVs in the treatment of cardiovascular diseases, nervous system diseases, liver diseases, renal diseases, malignant tumors and other diseases in recent years. EVs may play an important role in the pharmacological effect of some Chinese medicinal herbs in the treatment of diseases as an intermediary substance. EVs have the characteristics of long-distance transportation, which is consistent with the movement of Qi in TCM. EVs carry a variety of functional molecules, which is consistent with the function of Qi. As the potential material basis of Qi in TCM, the function of EVs is worth further study.
ABSTRACT
To screen novel anti-dengue virus (DENV) NS5 RdRp enzyme inhibitors, a series of 5-cyano-2-thiacetoaryl pyrimidinone compounds were designed and synthesized by molecular hybridization method with HCV NS5B RdRp inhibitor 3jc and ZIKV NS5 RdRp inhibitor 4w as lead compounds. The anti-DENV activity of these compounds was evaluated by MTT assay and plaque assay and five compounds showed anti-DENV activity. The most active compound 7a'k showed better anti-DENV activity than that of the positive control ribavirin (EC50 = 7.86 μmol·L-1 vs EC50 = 18.07 μmol·L-1), and the other four compounds showed almost the same anti-DENV activity as ribavirin. Finally, the prediction and simulation of the binding mode through molecular provided new ideas for the further development of this new DENV NS5 RdRp inhibitor.
ABSTRACT
@#During the new coronavirus disease 2019 (COVID-19) pandemic, there has been controversy over whether emergency surgical management should be performed or not in the patients with COVID-19. Stanford type A aortic dissection is a very urgent life-threatening disease, and guidelines recommend surgical treatment for patients with type A aortic dissection in the first instance. However, intraoperative extracorporeal circulation can be fatal to patients recovering from COVID-19. During the pandemic, extracorporeal membrane oxygenation (ECMO) has played an important role in supporting COVID-19 patients with acute respiratory failure. This article reports a successful V-V ECMO treatment for a Stanford type A aortic dissection patient, who suffered respiratory failure caused by COVID-19 after emergency surgery.
ABSTRACT
Objective:To explore any effect of upper limb swing training guided by rhythmic auditory stimulation (RAS) on the walking ability of stroke survivors.Methods:Eighty stroke survivors were randomly divided into an observation group and a control group. Both groups received conventional rehabilitation treatment, including neuromuscular facilitation, muscle strength training, balance training and gait training, but the observation group was additionally provided with RAS-guided upper limb swing training for 20min once a day, 5d per week for 6 weeks. Before and after the intervention, balance and lower limb function were quantified in both groups using Holden′s walking function classification, the Fugl-Meyer lower extremity motor function scale (FMA-LE), the Berg Balance Scale (BBS) and the 10m walk test (10MWT). Limits of stability were also quantified.Results:After the treatment, the average Holden, FMA-LE and BBS scores, as well as the average 10MWT time were significantly better in the observation group than in the control group. The average stability limits and their maintenance were also superior.Conclusion:RAS-guided upper limb swing training can improve the gait, walking ability, walking stability, walking speed and balance of stroke survivors.
ABSTRACT
Objective:To explore the status of coronavirus disease 2019 (COVID-19) vaccines, safety and the influencing factors of adverse reactions in maintenance hemodialysis (MHD) patients.Methods:The study was a retrospective study. The MHD patients vaccinated with COVID-19 vaccines in Tianjin city from January 2020 to July 2022 were enrolled in the study. The data of general information, vaccination situation, adverse reactions, and laboratory tests before and after vaccination were collected. Logistic regression analysis was used to analyze the risk factors of adverse reactions after vaccination.Results:A total of 7 375 patients were registered to receive hemodialysis treatment in Tianjin city, of whom 1 036 patients (14.05%) vaccinated with COVID-19 vaccines were enrolled from 53 hemodialysis centers in the study, with age of (54.00±13.27) years old (17-88 years old), and 676 males (65.25%). There were 171 patients (16.51%) receiving the first dose of vaccines only, 464 patients (44.79%) receiving two doses of vaccines, 401 patients (38.71%) receiving three doses of vaccines, and 67 patients (6.47%) had adverse reactions. No serious adverse reaction occurred. The number of neutrophils after vaccination was lower than that before vaccination ( P < 0.05), while the number of lymphocytes, alanine aminotransferase, glutamic oxaloacetic aminotransferase, and serum albumin after vaccination were higher than those before vaccination (all P < 0.05). Logistic regression analysis showed that age ( OR=0.967, 95% CI 0.946-0.990, P=0.005), previous allergic history ( OR=0.013, 95% CI 0.001-0.151, P < 0.001), serum uric acid ( OR=1.004, 95% CI 1.001-1.008, P=0.020), numbers of vaccinations administered ( OR=0.505, 95% CI 0.330-0.774, P=0.002), leukocytes ( OR=0.766, 95% CI 0.628-0.935, P=0.009) and lymphocytes ( OR=0.082, 95% CI 0.045-0.148, P < 0.001) were independently correlated with the incidence of adverse reactions. Conclusions:The proportion of MHD patients vaccinated with COVID-19 vaccines is 14.05%. The incidence of adverse reactions is 6.47%, and there is no serious adverse reaction. Age, previous allergic history, serum uric acid, and numbers of vaccinations administered, leukocytes and lymphocytes are independently correlated with the incidence of adverse reactions in MHD patients.
ABSTRACT
Parkinson′s disease (PD) is a common neurodegenerative disease. The prevalence of dysphagia in patients with PD is 16%-87%. Dysphagic patients show abnormalities in the oral, pharyngeal and esophageal phases of swallowing. The evaluation tools of dysphagia in patients with PD include instrumental assessment tools, non-instrumental objective assessment tools and subjective assessment tools. Videofluoroscopic study of swallowing and flexible endoscopic examination of swallowing are the gold standards for swallowing assessment in patients with PD; high-resolution manometry, tongue pressure measurement, surface electromyography and ultrasonography can be used as supplementary tests; the Swallowing Disturbance Questionnaire Scale, which is sensitive, specific, reliable and valid, is recommended as a screening tool.
ABSTRACT
Objective:To determine the median effective dose(ED 50) of alfentanil combined with propofol inhibiting responses to the laryngeal mask airway(LMA) insertion in children. Methods:American Society of Anesthesiologists Physical Status classification Ⅰ children, aged 6-10 yr, with body mass index of 18-24 kg/m 2, undergoing facial skin pigmented nevus resection, were selected. Propofol(target plasma concentration 3 μg/ml) was given by the target-controlled infusion, alfentanil was intravenously injected, 2 min later LMA was inserted, and anesthesia was maintained with 2%-3% sevoflurane until the end of surgery. The dose of alfentanil was determined by the up-and-down sequential method, the initial dose of alfentanil was 15 μg/kg, when the response to LMA insertion was positive/negative, the dose of alfentanil increased/decreased by 1 μg/kg in the next case. The LMA insertion response was defined as swallowing, bucking, body movement occurred during insertion of the LMA, and this process was repeated until 7th turning points appeared. The ED 50 and 95% confidence interval of alfentanil combined with propofol inhibiting responses to LMA insertion in children were calculated using probit method. Results:The ED 50 of alfentanil combined with propofol inhibiting responses to LMA insertion was 13.18(95% confidence interval 12.43-13.79) μg/kg in children. Conclusions:The ED 50 of alfentanil combined with propofol inhibiting responses to LMA insertion is 13.18 μg/kg in children.
ABSTRACT
Objective:To evaluate the clinical efficacy and safety of retrograde intrarenal surgery(RIRS) and miniaturized percutaneous nephrolithotomy(mini-PCNL) in the treatment of lower pole kidney stones with a diameter <1.5 cm.Methods:The data of 95 patients with lower pole kidney stones with a diameter <1.5 cm treated in Renmin Hospital of Wuhan University from June 2017 to October 2020 were retrospectively analyzed. According to different surgical methods, the patients were divided into RIRS group and mini-PCNL group. There were 51 cases in RIRS group and 44 cases in mini-PCNL group. There was no significant difference in age [(48.2±11.4) years vs. (46.4±14.1) years], body mass index [(21.9±2.4) kg/m 2 vs. (20.7±3.2) kg/m 2], gender [male/female: 37/14 vs. 24/20], stone CT [(746.42±164.24)HU vs. (858.62±148.72)HU], creatinine [(71.3±21.6)μmol/L vs. (63.5±20.3)μmol/L], stone location (left/right: 26/25 vs. 23/21), stone diameter [(10.5±2.1) mm vs. (12.5±2.4) mm], infundibulopelvic angle [(43.32±9.42) degrees vs. (43.82±10.34) degrees], infundibular length [(24.92±4.85)mm vs. (24.37±5.26)mm] and infundibular [(9.26±3.04)mm vs.(9.46±2.94)mm] between the two groups ( P>0.05). The operation time, stone-free rate, hospital stay and postoperative complications between the two groups were compared. Results:Compared with the mini-PCNL group, the RIRS group had significantly smaller decrease in postoperative hemoglobin [(1.53±0.92) g/L vs. (4.54±2.46) g/L, P<0.05], the postoperative hospital stay was shorter [(2.52±0.94) d vs. (4.51±1.25)d, P<0.05], and postoperative visual analogue score was lower [(2.43±0.92) vs. (3.24±0.76), P<0.05]. The operation time of the mini-PCNL group was shorter than that of the RIRS group [(42.32±13.28) min vs. (54.24±14.43)min, P<0.05]. There was no significant difference in postoperative complications [5.9% (3/51) vs. 11.4% (5/44), P>0.05], postoperative cveatinine [(71.3±21.6) μmol/L vs. (63.5±20.3) μmol/L, P>0.05], postoperative intestinal function recovery time [(25.46±10.28)h vs. (32.43±9.25)h, P>0.05] and stone-free rate [92.2% (47/51) vs. 97.7% (43/ 44), P>0.05] between the two groups. Conclusions:Both RIRS and mini-PCNL are effective and safe minimally invasive treatments for lower pole kidney stones with a diameter < 1.5 cm. RIRS has shorter operation time, less blood loss, lower pain score and faster postoperative recovery.
ABSTRACT
Objective:To evaluate the efficacy and safety of non-osteotomy total hip arthroplasty (THA) in the treatment of Crowe IV developmental dysplasia of the hip (DDH).Methods:From Jan 2013 to Sep 2021, 46 patients (46 hips) in our department who underwent total hip arthroplasty without osteotomy for unilateral Crowe IV DDH were retrospectively analyzed, including 6 males and 40 females, with an average age of 41.2±7.2 years (25-61 years). The reduction of the femoral head was achieved successfully through moderate upward-posterior displacement of the movement center, gradual osteotomy of the calcar femorale, proper sinking of the femoral prosthesis and sufficient soft tissue release. The evaluation indexes included the basic condition of the operation (operation time, blood loss, blood transfusion, volume), clinical evaluation (Harris score of hip joint function, patient satisfaction, Trendelenburg sign), imaging evaluation (measurement of limb length and pelvic inclination) and incidence of complications.Results:The mean follow-up time was 72.2±8.8 months (8-101 months). The operation time was 97.2±12 min (84-112 min). The average intraoperative bleeding volume was 550±60 ml (350-850 ml). No patient had periprosthetic infection or fracture, no periprosthetic osteolysis or prosthesis loosening, and no patient needed revision surgery at the last follow-up of all cases. The average HHS score of patients increased from 42.5±12.3 points before surgery to 89.2±10.8 points at the last follow-up, and the difference was statistically significant ( t=19.35, P<0.001). Patient self-rated satisfaction: none was very dissatisfied, 1 patient were less satisfied (2%, 1/46), 4 patients were average (9%, 4/46), 19 patients were relatively satisfied (41%, 19/46), and 22 patients were very satisfied (48%, 22/46). The Trendelenburg sign of 46 cases was positive before operation, and all were negative at the last follow-up. The patients' true leg length discrepancy (LLD) measurement was -2.5±0.6 mm before surgery and 11.5±3.2 mm at the last follow-up ( t=29.17, P<0.05). Patients' perceived LLD was 28.2±5.1 mm before surgery and 3.4±1.4 mm at the last follow-up ( t=32.18, P<0.05). The length of the residual calcar femorale was 3.2±0.4 mm after THA. The limb extended distance of affected limb was 45.2±4.6 mm. The preoperative iliolumbar angle was -6.5°±2.3°, which returned to -0.5°±1.3° at the last follow-up ( F=651.97, P<0.05). Conclusion:For patients with unilateral type IV DDH, non-osteotomy THA is a safe and effective surgical method with simple operation and few complications. It can quickly correct pelvic tilt and lumbar compensatory scoliosis postoperatively.
ABSTRACT
Objective To analyze the relationship between dietary and lifestyle inflammatory scores and metabolic syndrome, diabetes mellitus, cardiovascular disease, non-alcoholic fatty liver disease, tumor and other common metabolic diseases, and to explore the impact of dietary and lifestyle inflammatory potential on metabolic diseases, so as to provide new ideas for the diagnosis, treatment and prevention of metabolic diseases. Methods Databases such as CNKI, Wanfang , and PubMed were searched, and literatures related to the dietary and lifestyle inflammatory scores (DLIS) and metabolic diseases were reviewed . Results Seven articles showed that dietary and lifestyle inflammation scores had a positive correlation with metabolic diseases, and two articles showed that only lifestyle inflammatory scores had a positive correlation with metabolic diseases. Conclusion Dietary and lifestyle inflammatory scores may be positively correlated with metabolic diseases, but some results are still controversial. Further studies are needed to prove the correlation between DLIS and metabolic diseases.
ABSTRACT
Objective To establish a new model of indocyanine green (ICG) clearance test combined with total bilirubin actual resident rate (TBARR) for predicting the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) treated with artificial liver support system (ALSS) therapy. Methods A retrospective analysis was performed for the clinical data of 136 patients with HBV-ACLF who underwent ALSS therapy in Department of Infectious Diseases, The Affiliated Hospital of Southwest Medical University, from June 2017 to July 2021, and according to the prognosis at 3-month follow-up, they were divided into survival group with 92 patients and death group with 44 patients. Related indicators were measured at the time of the confirmed diagnosis of ACLF, including biochemical parameters, coagulation, indocyanine green retention rate at 15 minutes (ICGR 15 ), and effective hepatic blood flow (EHBF), and related indices were calculated, including Model for End-Stage Liver Disease (MELD) score, MELD difference (ΔMELD), Child-Turcotte-Pugh (CTP) score, total bilirubin clearance rate (TBCR), total bilirubin rebound rate (TBRR), and TBARR. The Mann-Whitney U test was used for comparison of continuous data with skewed distribution between two groups; the chi-square test was used for comparison of categorical data between groups. A binary logistic regression analysis was used to establish a combined predictive model for the prognosis of HBV-ACLF after ALSS therapy. The area under the ROC curve (AUC) was used to compare the accuracy of various models in judging the short-term prognosis of patients with HBV-ACLF after ALSS therapy, and the Z test was used for comparison of AUC. Results There were significant differences between the death group and the survival group in MELD score, ΔMELD, CTP score, ICGR 15 , EHBF, TBRR, TBARR, neutrophil count, percentage of neutrophils, lymphocyte count, platelet count, alkaline phosphatase, gamma-glutamyl transpeptidase, total bilirubin, albumin, prothrombin time, international normalized ratio, prothrombin time activity, prealbumin, fibrinogen, serum sodium, age, and the incidence rate of hepatic encephalopathy (all P 80%. Conclusion The combined predictive model established by ICGR 15 and TBARR has a good value for in predicting the short-term prognosis of patients with HBV-ACLF after ALSS therapy, and the combined predictive model has a better accuracy than the single model in judging prognosis.
ABSTRACT
According to the theory of 'Xingben Dazao' of Psoralea corylifolia Linn. (BL), the susceptible syndromes and biomarkers of liver injury caused by BL were searched. Rat models of kidney-yin deficiency syndrome (M_yin) and kidney-yang deficiency syndrome (M_yang) were established, and all animal experimental operations and welfare following the provisions of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Traditional Chinese Medicine (No. YFYDW2020017). The results showed that BL significantly decreased the body weight, water intake, and urine weight of M_yin rats and increase the organ indexes of the liver, testis, adrenal gland, and spleen and the expression of alanine aminotransferase (ALT). Meantime, BL significantly increased the urine weight of M_yang rats and decreased the expression of ALT and aspartate aminotransferase (AST). Hematoxylin and eosin (HE) staining showed that BL could aggravate inflammatory infiltration of hepatocytes in rats with M_yin and alleviate liver injury in rats with M_yang. Metabolomics identified 17 BL co-regulated significant differential metabolic markers in M_yin and M_yang rats. Among them, 8 metabolites such as glutamine, quinolinate, biliverdin, and lactosylceramide showed opposite trends, mainly involving cysteine and methionine metabolism, tyrosine metabolism, tryptophan metabolism, purine metabolism, sphingolipid metabolism, glycerol phospholipid metabolism, glutamine metabolism, and other pathways. M_yin/M_yang may be the susceptible constitution of BL for liver damage or protection, which may be related to the regulation of amino acid metabolism and sphingolipid metabolism. The study can provide some experimental data support for the safe and accurate use of BL in the clinical practice of traditional Chinese medicine.
