ABSTRACT

Age-related ovarian hypofunction includes a decrease in follicle quantity and quality as well as alterations in the ovarian microenvironment,the mechanisms of which are mainly related to mitochondrial dysfunction,free radical and antioxidant systems,telomere and telomerase alterations,and apoptosis,and is one of the major factors contributing to infertility in advanced maternal age (AMA). Despite the tremendous progress in assisted reproductive technology in recent decades,few breakthroughs have been made in alleviating age-related ovarian hypofunction and improving reproductive outcomes for AMA. In recent years,there has been an increasing number of studies on the multi-level and multi-targeted mechanisms of traditional Chinese medicine (TCM) to improve age-related ovarian hypofunction by modulating mitochondrial homeostasis,alleviating oxidative stress,and inhibiting apoptosis,while more high-quality randomized controlled trials have demonstrated the clinical efficacy of TCM in assisted reproductive technology. Given this,this article presented a systematic review of recent research and randomized controlled trials on the mechanism of Chinese medicine active ingredients,single Chinese medicine, and Chinese medicine compounds in delaying age-related ovarian hypofunction,to clarify the current status and shortcomings of the research. This paper provides medication management of TCM for effectively alleviating age-related ovarian hypofunction and improving reproductive outcomes for AMA.

ABSTRACT

Objective:To investigate the safety and effectiveness of robot-assisted total knee arthroplasty (TKA).Methods:From August 2021 to March 2022, the data of 69 patients who received robot-assisted TKA for inflammatory disease of knee in 6 hospitals were collected, including 24 males and 45 females, aged 52±6 years (range, 46-72 years), including 53 cases of knee osteoarthritis,10 cases of rheumatoid arthritis, and 6 cases of traumatic arthritis. Imaging data examination of patients was completed according to the multicenter specification. Preoperatively, the patient's CT data were extracted before surgery and a personalized prosthesis positioning plan was designed by the robotic system to determine the prosthesis size, lower limb force lines, and femoral and tibial osteotomy volumes; intraoperatively, the osteotomy template was robotically controlled to complete the osteotomy according to the prosthesis positioning plan, and the intraoperative osteotomy volumes were measured to verify the accuracy of the robot-assisted TKA osteotomy with the preoperative planning. Postoperatively, the lateral angle of the distal femur, the medial angle of the proximal tibia and the hip-knee-ankle angle were measured in the coronal plane according to radiographs; the postoperative outcome was evaluated 3 months after operation, using the American Knee Society score (KSS), including the KSS knee score and functional score.Results:The operative time was 97.3±2.3 min (range, 80-110 min) and the amount of bleeding was 320.0±6.2 ml (range, 300-350 ml) in 69 patients. Three months after operation, the mean range of motion of knee joint was increased from 82.2°±1.1° before surgery to 119.7°±0.8° after surgery ( t=27.65, P<0.001), and the line of force of lower limb was improved from 160.9°±0.5° before surgery to 178.0°±0.2° after surgery ( t=32.03, P<0.001). KSS-knee score increased from 54.8±0.7 points before operation to 85.0±0.5 points after operation, and KSS-functional score increased from 56.5±0.7 points before operation to 85.9±0.4 points after operation, the difference was statistically significant ( t=35.45, 36.58, P<0.001). The proportion of patients with intraoperative femoral and tibial osteotomies within 2 mm osteotomy error compared with preoperative planning was 97% for the lateral tibial plateau, 100% for the medial tibial plateau, 100% for the lateral distal femur, 99% for the medial distal femur, 93% for the lateral posterior femoral condyle, and 100% for the medial posterior femoral condyle; The proportion of patients with postoperative anteroposterior X-ray measurement angle error within 3° was: 100.0% for the distal lateral femoral angle, 100.0% for the proximal medial tibial angle, and 100% for the hip-knee-ankle angle. No complications occurred in all patients except for one case in which fat liquefaction occurred in the postoperative wound. Conclusion:Robot-assisted TKA is a safe and effective surgical method for the treatment of inflammatory disease of knee with accurate prosthesis installation and good postoperative recovery of lower limb alignment.

ABSTRACT

Objective:To explore the application value of computed tomography (CT) plain scan and dynamic enhanced scan in the diagnosis of solitary pulmonary nodules.Methods:The clinical data of 120 patients with solitary pulmonary nodules detected by physical examination in Baoding First Central Hospital from January 2018 to December 2020 were retrospectively reviewed. All patients were confirmed by surgery and pathology, including 77 benign lesions and 43 malignant lesions; All patients underwent CT plain scan and dynamic enhanced scan before operation. The accuracy of the two examination methods in the diagnosis of benign and malignant lesions of solitary pulmonary nodules was analyzed and compared. The detection rate of CT dynamic enhanced scan imaging characteristics (vacuole sign, ground glass sign, spinous sign, lobulation sign, hair prick sign, blood vessel cluster, pleural depression) of benign and malignant lesions of solitary pulmonary nodules was compared, and the diagnostic value of CT plain scan and dynamic enhanced scan in the differential diagnosis of benign and malignant solitary pulmonary nodules was evaluated based on the results of surgical pathological diagnosis. The manifestations and characteristic curves of CT dynamic enhanced scan of solitary pulmonary nodules was analyzed.Results:The diagnostic accuracy of CT dynamic enhanced scan for solitary pulmonary nodules was 80.00% (96/120), which was higher than that of CT plain scan (63.33%) (76/120) ( P<0.05). The sensitivity, specificity, and negative predictive value of CT dynamic enhanced scan for the diagnosis of benign and malignant lesions of solitary pulmonary nodules were higher than those of CT plain scan (all P<0.05). Among the imaging characteristics of CT dynamic enhanced scans of malignant lesions, the ground glass sign, spinous process sign, lobulation sign, spiculation sign, vascular clustering and pleural indentation were detected more frequently than those of benign lesions (all P<0.05). Benign lesions usually showed homogeneous enhancement, and a few showed heterogeneous enhancement; Malignant nodules often showed uneven enhancement, and a few had even enhancement. The time density curves of dynamic enhanced CT values in the regions of interest of benign and malignant solitary pulmonary nodules were different. Conclusions:The value of dynamic enhanced CT scan in the differential diagnosis of benign and malignant lesions of solitary pulmonary nodules is higher than that of CT plain scan, and the imaging features are obvious, with higher sensitivity and specificity, which is worthy of application.

ABSTRACT

Objective:To investigate the safety and efficacy of remimazolam combined with afentanyl for fiberoptic bronchoscopy.Methods:Sixty patients admitted to Chifeng Hospital for fiberbronchoscopy from January to April 2022 were selected and divided into two groups by random number table method: remimazolam group (group R) and propofol group (group P), 30cases in each group. After intravenous injection of alfentanil for anesthesia induction, group R was sedated by intravenous injection of remidazolam besylate, and group P was sedated by intravenous injection of propofol emulsion. When sufficient sedation was achieved, fiberoptic bronchoscopy was performed. The patients were scored with the Mini-Mental State Examination (MMSE) before examination and before leaving the room. The recovery rate of sedation and the recovery rate of drugs during operation were compared. Blood pressure, heart rate (HR), bispectral index (BIS), SpO 2 value and Modified Observer′s Assessment of Alertness/Sedation (MOAA/S) score were compared before induction (T 0), at the beginning of examination (T 1), immediately when fiber bronchoscope reached juga (T 2), at the end of surgery (T 3), immediately, when patients regained consciousness (T 4). Drug onset and recovery time (time out of hospital) as well as the incidence of intraoperative and postoperative adverse reactions were recorded in both groups. Results:There was no statistically significant difference in general condition, MMSE score and examination time between the two groups (all P>0.05). There was no statistically significant difference between the two groups in the success rate of sedation and the number of sedative remedy times (all P>0.05). The number of additional drugs in group R was significantly higher than that in group P ( P<0.05). The systolic blood pressure, diastolic blood pressure and BIS values of patients in group P at T 1 and T 2 were significantly lower than those in group R (all P<0.05). After administration, the MOAA/S score of the two groups began to decrease, and the decrease of the P group was significantly greater than that of the R group, and the MOAA/S value of the patients was the lowest at the 3rd and 4th minutes after administration, respectively. The time from the beginning of administration to the MOAA/S score ≤3 in group P was significantly shorter than that in group R (all P<0.05). The incidence of pain and respiratory depression after injection in group P was significantly higher than that in group R ( P<0.05). Conclusions:The application of afentanil combined with remimazolam in the patients undergoing fiberoptic bronchoscopy has good sedative effect and high anesthesia quality, and has no obvious effect on cognitive function and few adverse reactions, so it is safe and effective.

ABSTRACT

Objective: To investigate the clinicopathological features, treatment and prognosis of maxillofacial neuroendocrine carcinoma. Methods: A total of 11 patients with maxillofacial neuroendocrine carcinoma diagnosed in the Department of Pathology of The First Affiliated Hospital of Zhengzhou University from December 2010 to July 2022 were retrospectively enrolled, including 8 males and 3 females, aged (65.2±9.5) years (ranged from 49 to 87 years), with a disease course of 0.5 to 6.0 months. The clinicopathological data including head and neck CT, MRI and treatment methods were analyzed. Results: Submandibular gland and maxilla were involved in 3 cases, parapharynx in 2 cases, and face, tongue root and soft palate in 1 case respectively. Clinically, the initial symptom is a rapidly growing painless or tender mass, which may be accompanied by restricted mouth opening, dysphagia, and local numbness after invasion of masticatory muscles and nerves. The tumors were all invasive and low-density, with unclear boundaries from the surrounding tissues. Among the patients, 9 received surgical treatment, and 5 received adjuvant treatment after surgery (2 received chemotherapy, 3 received radiotherapy+chemotherapy). According to the 5th edition of the World Health Organization classification of head and neck tumors in 2022, there were 1 case (1/11) with poorly differentiated large cells and 10 cases (10/11) with poorly differentiated small cells. Histologically, the macrocell type is composed of large cells with rough chromatin, obvious vacuolar nucleolus, protruding nucleolus, and necrosis. The small cell type is dominated by small blue round cells with neuroendocrine characteristics, with active growth and multifocal necrosis. Immunohistochemical staining showed that cytokeratin (CK), epithelial membrane antigen (EMA) and synaptophysin (Syn) were diffusively expressed, 10 cases expressed CD56, 8 cases expressed p63, 6 cases expressed weakly punctated chromograin-A (CgA), and S-100 was not expressed. The Ki-67 index ranges from 20 to 90 percent. By the end of follow-up (0.5 to 127.0 months), 3 patients were alive, and the mean progression-free survival (21.0 months) of postoperative chemoradiotherapy patients was significantly longer than that of surgery and/or chemotherapy alone (3.3 months). Conclusions: Maxillofacial neuroendocrine carcinoma is characterized by low differentiation of small cells, high degree of malignancy and poor prognosis. Radical surgery combined with chemoradiotherapy has better local control effect.

ABSTRACT

Objective: To analyze correlation of occupational hydrogen fluoride exposure to low doses of bone metabolism index through occupational epidemiological investigation and benchmark dose calculation. Methods: In May 2021, using cluster sampling method, 237 workers exposed to hydrogen fluoride in a company were selected as the contact group, and 83 workers not exposed to hydrogen fluoride in an electronics production company were selected as the control group. The external exposure dose and urinary fluoride concentration, blood and urine biochemical indicators of the workers was measured.The relationship between external dose and internal dose of hydrogen fluoride was analyzed. The external dose, urinary fluoride was used as exposure biomarkers, while serum osteocalcin (BGP), serum alkaline phosphatase (AKP) and urinary hydroxyproline (HYP) were used as effect biomarkers for bone metabolism of hydrogen fluoride exposure. The benchmark dose calculation software (BMDS1.3.2) was used to calculate benchmark dose (BMD) . Results: Urine fluoride concentration in the contact group was correlated with creatinine-adjusted urine fluoride concentration (r=0.69, P=0.001). There was no significant correlation between the external dose of hydrogen fluoride and urine fluoride in the contact group (r=0.03, P=0.132). The concentrations of urine fluoride in the contact group and the control group were (0.81±0.61) and (0.45±0.14) mg/L, respectively, and the difference between the two groups was statistically significant (t=5.01, P=0.025). Using BGP, AKP and HYP as effect indexes, the urinary BMDL-05 values were 1.28, 1.47 and 1.08 mg/L, respectively. Conclusion: Urinary fluoride can sensitively reflect the changes in the effect indexes of biochemical indexes of bone metabolism. BGP and HYP can be used as early sensitive effect indexes of occupational hydrogen fluoride exposure.

ABSTRACT

Objective: To accurately screen non-small cell lung cancer (NSCLC) patients with KRAS G12C mutation and to evaluate their clinicopathological features, prognostic factors and current treatment status. Methods: A total of 19 410 NSCLC cases diagnosed at the Department of Pathology of Shanghai Chest Hospital, Shanghai, China from January 2018 to September 2021 were retrospectively reviewed, and the cases with KRAS gene mutation detected by next-generation sequencing were included. The clinicopathological and genetic mutation data of these cases were collected and analyzed. Results: A total of 1 633 (8.4%) NSCLC patients carried a KRAS gene mutation, among whom G12C was the most frequent (468 cases, 28.7%) mutant subtype. The mutation was more commonly found in males (414/468, 88.5%), patients with a history of smoking (308/468, 65.8%), and patients with a pathological type of invasive adenocarcinoma (231/468, 49.4%). The most common co-mutated genes in KRAS G12C mutant NSCLC were TP53 (52.4%, 245/468), STK11 (18.6%, 87/468) and ATM (13.2%, 62/468). The proportion of PD-L1 expression (≥1%) in KRAS G12C mutant NSCLC was significantly higher than that in patients without G12C mutation [64.3% (90/140) vs. 56.1% (193/344), P=0.014]. Immune checkpoint inhibitors (ICIs) treatment significantly prolonged progression-free survival (PFS) in NSCLC patients (10.0 months vs. 5.0 months, P=0.011). However, combination of chemotherapy and ICIs with anti-angiogenesis inhibitors or multi-target inhibitors did not significantly improve PFS in patients with KRAS G12C mutant NSCLC (P>0.05). Patients with KRAS G12C mutation NSCLC treated with ICIs and KRAS G12C patients with TP53 mutation had significantly longer median PFS than those with STK11 mutation (9.0 months vs. 4.3 months, P=0.012). Conclusions: Patients with KRAS G12C mutant NSCLC have relatively higher levels of PD-L1 expression and can benefit from ICIs treatment. The feasibility of chemotherapy, ICIs therapy and their combination needs further investigation.

ABSTRACT

OBJECTIVE To mine the focus and emotional attitude of the public on rare diseases, and to provide decision- making reference for relevant departments to formulate and implement relevant policies, systems and strategies for medical security of rare diseases. METHODS Latent Dirichlet allocation (LDA) topic model and sentiment analysis method were used to analyze the comment text of short videos related to the “nosinasine” medical insurance admission event on the Bilibili video website, mine the theme and sentiment tendency of the text, and put forward relevant strategy suggestions. RESULTS A total of 8 videos with tens of thousands of playback and 7 109 text data were obtained. According to the LDA analysis, online public paid attention to 9 topics related to rare diseases (the price of rare disease drugs, the inclusion of rare disease drugs in medical insurance, the status quo of research and development of rare disease drugs, the scope of medical insurance and the medical security system, the plight of rare disease patients, the prevention and screening of rare diseases, the value of rare disease drugs in medical insurance, the Chinese and western medical methods of rare diseases, and the supply and demand status of rare disease drugs), which could be summarized into 4 categories according to the objects of concern (rare disease drugs, rare disease medical insurance, rare disease medical and health services and rare disease patient groups). On the whole, the emotional tendency of the Internet public towards each topic showed a low positive and high negative tendency. CONCLUSIONS The public paid more attention to the price, research and development, supply and demand of rare disease drugs, and was deeply worried about the current medical status of rare diseases in China. To strengthen and improve the medical security for patients with rare diseases, such as actively carrying out public health services for rare diseases, strengthening cooperation in the diagnosis and treatment of rare diseases, and researching rare disease drugs, etc. Chinese medical and health departments can make concerted efforts in medical and health services, drug supply security, medical security and other social security.

ABSTRACT

ObjectiveTo study the changes of mitochondrial function of ovarian granulosa cells in women of different ages and the effect of Erzhi-Tiangui prescription on in vitro fertilization-embryo transfer (IVF-ET) outcomes for elderly women, so as to verify the connotation of the "Seven-Seven" theory in the Huangdi's Internal Classic (《黄帝内经》). MethodA total of 150 infertility patients undergoing IVF-ET at the Reproductive and Genetic Center of Integrative Medicine, Affiliated Hospital of Shandong University of Traditional Chinese Medicine were recruited and assigned into "hree-Seven/Four-Seven (30 cases), Five-Seven (60 cases), and Six-Seven (60 cases) groups according to the "Seven-Seven" theory. The Five-Seven and Six-Seven groups were further assigned into control and Chinese medicine subgroups using the random number plus envelope method, and the Chinese medicine group was administrated with Erzhi Tiangui prescription from the start day of controlled ovulation stimulation cycle to the trigger day. The IVF outcome was observed, and Western blot was employed to determine the levels of mitofusin 1 (MFN1), mitofusin 2 (MFN2), and dynamin-related protein 1 (Drp1) in the ovarian granulosa cells. ResultCompared with the Three-Seven/Four-Seven group, the control subgroups of the Five-Seven and Six-Seven groups showed decreased retrieved oocytes, two pronuclear (2PN) embryos, available embryos, high-quality embryos, clinical pregnancy rate, and live birth rate (P<0.05). Moreover, the control subgroup of the Six-Seven group showed decreased fresh embryo transfer rate(P<0.05). Compared with the control subgroup of the Five-Seven group, that of the Six-Seven group showed reduced retrieved oocytes, 2PN embryos, available embryos, high-quality embryos, and clinical pregnancy rate (P<0.05). The Chinese medicine subgroup had more retrieved oocytes, 2PN oocytes, and available embryos than the control subgroup in the Five-Seven groups (P<0.05). The Chinese medicine subgroup had more retrieved oocytes, than the control subgroup in the Six-Seven groups (P<0.05). The control subgroup of the Six-Seven group showed lower expression levels of Mfn1 and Mfn2 and higher level of Drp1 than the control subgroup of the Five-Seven group (P<0.05), which indicated that the levels of Mfn1 and Mfn2 in ovarian granulosa cells were down-regulated while the expression of Drp1 was up-regulated with aging (P<0.05). The Chinese medicine subgroup had higher Mfn2 level and lower Drp1 level than the control subgroup in the Five-Seven group (P<0.05), and the Chinese medicine subgroup had higher Mfn1 and Mfn2 levels and lower Drp1 level than then control subgroup in the Six-Seven group (P<0.05). ConclusionsThe prognosis of IVF in women after "Five-Seven" became worse with aging, and the mitochondria in ovarian granulosa cells showed decreased fusion ability and increased fission, which verified the connotation of the "Seven-Seven" theory from the mitochondrial function. Erzhi Tiangui prescription can regulate the mitochondrial function of ovarian granulosa cells in elderly women, up-regulate the expression levels of Mfn1 and Mfn2 to promote mitochondrial fusion, and down-regulate the expression of Drp1 to reduce mitochondrial fission, thus alleviating the ovarian hypofunction caused by aging, improve the development potential of oocytes, and improve the IVF outcomes of elderly women. However, this prescription has limited efficacy for the elderly women in the age range of "Six-Seven".

ABSTRACT

ObjectiveTo explore the effect of targeted intervention measures based on risk score of venous thromboembolism (VTE), on the prevention of senile type 2 diabetes inpatients, as well as their influence on the occurrence of venous thromboembolism. MethodsA total of 134 elderly patients with type 2 diabetes mellitus who were hospitalized in geriatrics department of Peking university third hospital during June 1, 2018 to September 30, 2018 were selected as the research subjects. All the patients were divided into control group and observation group according to random number table method, with 67 patients in each group. Patients in the control group were treated with conventional intervention methods, and patients in the observation group were treated with targeted intervention measures based on VTE risk score. After one month of intervention, the Padua score, blood glucose level and coagulation indexes of the two groups were compared. The incidence of thrombosis during the intervention period was also recorded. ResultsThe Padua score in observation group (2.09±2.17) points was significantly lower than that (3.19±2.37) points in control group (P<0.05). The indexes of fasting blood glucose, 2h postprandial blood glucose and HbA1c in observation group were significantly lower than those in control group (P<0.05). The fibrinogen, D-dimer, activated partial thromboplastin time and prothrombin time in observation group were significantly lower than those in control group (P<0.05). The incidence of DVT, PVT, lower limb swelling, pain and abnormal skin color in the observation group were 4.00%, 2.00%, 2.00%, 2.00%, and 0, respectively, and in the control group were 12.00%, 10.00%, 10.00%, 12.00%, and 8.00%, respectively. The incidence of adverse events in observation group was significantly lower than that in control group (P<0.05). ConclusionTargeted intervention based on VTE risk score can significantly reduce the risk of VTE occurrence, improve blood clotting function and blood glucose level in elderly patients with type 2 diabetes mellitus. This nursing measure has important clinical application value.

ABSTRACT

Objective: To assess the safety and efficacy of transcatheter fenestration closure following Fontan procedure with an atrial septal occluder. Methods: This is a retrospective study. The study sample consists of all consecutive patients who underwent closure of a fenestrated Fontan baffle at Shanghai Children's Medical Center Affiliated to Shanghai Jiaotong University School of Medicine between June 2002 and December 2019. The indications of Fontan fenestration closure included that normal ventricular function, targeted drugs for pulmonary hypertension and positive inotropic drugs were not required prior the procedure; and the Fontan circuit pressure was less than 16 mmHg (1 mmHg=0.133 kPa) and no more than a 2 mmHg increase during test occlusion of the fenestration. Electrocardiogram and echocardiography were reviewed at 24 hours, 1, 3, 6 months and annually thereafter post procedure. Follow-up information including clinical events and complications related to Fontan procedure was recorded. Results: A total of 11 patients, including 6 males and 5 females, aged (8.9±3.7) years old were included. The types of Fontan were extracardiac conduits (7 cases) and intra-atrial duct (4 cases). The interval between percutaneous fenestration closure and the Fontan procedure was (5.1±2.9) years. One patient reported recurrent headache after Fontan procedure. Successful fenestration occlusion with atrial septal occluder was achieved in all patients. Compared with prior closure, Fontan circuit pressure ((12.72±1.90) mmHg vs. (12.36±1.63) mmHg, P<0.05), and aortic oxygen saturation ((95.11±3.11)% vs. (86.35±7.26)%, P<0.01) were increased. There were no procedural complications. At a median follow-up of (3.8±1.2) years, there was no residual leak and evidence of stenosis within the Fontan circuit in all patient. No complication was observed during follow-up. One patient with preoperative headache did not have recurrent headache after closure. Conclusions: If the Fontan pressure is acceptable by test occlusion during the catheterization procedure, Fontan fenestration could be occluded with the atrial septum defect device. It is a safe and effective procedure, and could be used for occlusion of Fontan fenestration with varying sizes and morphologies.

ABSTRACT

Objective: To evaluate the effectiveness and safety of Pul-Stent as the treatment of postoperative branch pulmonary artery stenosis in children with congenital heart disease. Methods: This was a retrospective study. Thirty-three patients who underwent Pul-Stent implantation in Shanghai Children's Medical Center due to postoperative residual pulmonary artery stenosis from August 2014 to June 2015 were included. The immediate curative effect, follow-up and complications of Pul-Stent implantation were assessed. Comparisons between groups were performed with unpaired Student t test. Results: Pul-Stent implantation of 33 patients (19 males and 14 females) were performed successfully. Thirty-one patients underwent percutaneous stenting, and 2 patients underwent hybrid stenting. A total of 35 Pul-Stents were implanted (19 of model small, 15 of model medium and one of model large), 23 stents were planted in the proximal left pulmonary artery and 12 stents were in the proximal right pulmonary artery. The initial diameter of dilation balloon ranged from 6 to 16 mm, and the long sheath of percutaneous implantation ranged from 8 to 10 F in 29 patients (29/31, 94%). After stenting, the diameter of the narrowest segment of pulmonary artery increased from (4.0±1.7) mm to (9.1±2.1) mm in all patients (t=-21.60, P<0.001). The pressure gradient at the stenosis in 26 patients after biventricular correction decreased from (30.5±12.3) mmHg (1 mmHg=0.133 kPa) to (9.9±9.6) mmHg (t=12.92, P<0.001), and the right ventricular to aortic pressure ratio decreased from 0.57±0.14 to 0.44±0.12 (t=7.44, P<0.001). The pressure of the superior vena cava after stenting in 5 patients after cavopulmonary anastomosis decreased from (17.0±1.9) mmHg to (14.0±0.7) mmHg (t=2.86, P=0.046). Two patients died during reoperation for repairing other cardiac malformations. The remaining 31 patients were clinically stable during the follow-up period of (5.3±1.6) years, and one stent fracture was found on chest X-ray. Cardiac catheterization reexaminations in 16 patients showed that restenosis was found in one stent, while stent position and patency were satisfactory in the remaining stents. Nine children underwent post-dilation without stent fracture, displacement or aneurysm formation. Cardiac tomography showed no stent stenosis, fracture observed, or significant change in diameter of the stent in 8 patients. The inner diameter and pulmonary blood perfusion could not be accurately evaluated due to artifacts by cardiac magnetic resonance imaging in 4 patients. Conclusions: Pul-Stent has good compliance and adequate radial strength, and can dilate further over time to accommodate for somatic growth. It performs safely and effectively in treating post-operative branch pulmonary artery stenosis in children.

ABSTRACT

Objective: To evaluate the efficacy within the first 24 h post extracorporeal membrane pulmonary oxygenation (ECMO) and the impact of early efficacy on the prognosis of adult patients with fulminant myocarditis (FM). Methods: This retrospective case analysis study included hospitalized patients (age≥18 years) who were diagnosed with fulminant myocarditis from November 2016 to May 2021 in the First Affiliated Hospital of Zhengzhou University. Patients were divided into survival or non-survival groups according to treatment outcomes. The age, sex, treatments, drug use, ECMO use, clinical and laboratory data (before and 24 h after the use of ECMO) were analyzed. The change rate of clinical and laboratory data after 24 h use of ECMO was calculated to find differences between two groups. Multivariate logistic regression was used to analyze the related factors with in-hospital death and complication between the two groups. Results: A total of 38 FM patients treated with ECMO were included. There were 23 cases (60.5%) in the survival group, aged (39.6±13.7) years, and 17 (73.9%) cases were female. The total ECMO time was (134.4±71.3)h. There were 15 cases (39.5%) in non-survival group, aged (40.0±15.8) years, and there were 12(80.0%) female, the ECMO time was (120.1±72.4) h in this group. The proportion of tracheal intubation and continuous renal replacement therapy in the survivor group and dosage of norepinephrine within 24 h after ECMO implantation were significantly less than in non-survival group (all P<0.05). There was no significant difference in all efficacy related biochemical indexes between two groups before ECMO use. The levels of lactic acid, procalcitonin, creatinine, alanine aminotransferase, aspartate aminotransferase, creatine kinase-MB, cardiac troponin I and N-terminal B-type natriuretic peptide prosoma were significantly less in survival group than in non-survival group at 24 h after the use of ECMO (all P<0.05). Results of multivariate logistic regression analysis showed that the higher 24 h change rate of creatinine (OR=0.587, 95%CI 0.349-0.986, P=0.044) and creatine kinase-MB (OR=0.177, 95%CI 0.037-0.841, P=0.029) were positively correlated with reduced risk of in-hospital mortality. The central hemorrhage and acute kidney injury in survival group were less than in non-survivor group (P<0.05). Conclusions: After 24 h early use of ECMO in FM patients, the improvement of various efficacy related biochemical test indexes in the survival group was better than that in the non-survival group. Faster reduction of creatine kinase-MB and creatinine values within 24 h ECMO use is positively correlated with reduced risk of in-hospital mortality in adult patients with FM.

ABSTRACT

Objective:To observe and analyze the correlation between time within target glucose range (TIR) and hemoglobin A1c (HbA1c) and the risk of diabetic retinopathy (DR).Methods:A retrospective clinical study. From March 2020 to August 2021, 91 patients with type 2 diabetes mellitus (T2DM) who were hospitalized in Department of Endocrinology and Metabolic Diseases, Affiliated Hospital of Weifang Medical University, were included in the study. All patients underwent Oburg's no-dilatation ultra-wide-angle laser scan ophthalmoscopy, HbA1c and continuous glucose monitoring (CGM) examinations. According to the examination results and combined with the clinical diagnostic criteria of DR, the patients were divided into non-DR (NDR) group and DR group, with 50 and 41 cases respectively. The retrospective CGM system was used to monitor the subcutaneous interstitial fluid glucose for 7 to 14 consecutive days, and the TIR was calculated. Binary logistic regression was used to analyze the correlation between TIR, HbAlc and DR in patients with T2DM0. At the same time, a new indicator was generated, the predicted probability value (PRE_1), which was generated to represent the combined indicator of TIR and HbA1c in predicting the occurrence of DR. The receiver operating characteristic curve (ROC curve) was used to analyze the value of TIR, HbAlc and PRE_1 in predicting the occurrence of DR.Results:The TIR of patients in the NDR group and DR group were (81.58±15.51)% and (67.27±22.09)%, respectively, and HbA1c were (8.03±2.16)% and (9.01±2.01)%, respectively. The differences in TIR and HbA1c between the two groups of patients were statistically significant ( t=3.501,-2.208; P=0.001, 0.030). The results of binary logistic regression analysis showed that TIR, HbA1c and DR were significantly correlated (odds ratio=0.960, 1.254; P=0.002, 0.036). ROC curve analysis results showed that the area under the ROC curve (AUC) of TIR, HbA1c and PRE_1 predicting the risk of DR were 0.704, 0.668, and 0.707, respectively [95% confidence interval ( CI) 0.597-0.812, P=0.001; 95% CI 0.558-0.778, P=0.006; 95% CI 0.602-0.798, P=0.001]. There was no statistically significant difference between TIR, HbA1c and PRE_1 predicting the AUC of DR risk ( P>0.05). The linear equation between HbAlc and TIR was HbAlc (%) = 11.37-0.04×TIR (%). Conclusions:TIR and HbA1c are both related to DR and can predict the risk of DR. The combined use of the two does not improve the predictive value of DR. There is a linear correlation between TIR and HbAlc.

ABSTRACT

Objective:To observe any effect of supplementing continuous static stretching (CSS) with extracorporeal shock wave therapy (ESWT) in treating triceps surae spasm after a stroke.Methods:Sixty-four stroke survivors with triceps surae spasm were randomly divided into a conventional rehabilitation group, a shock wave group and a combined treatment group. In addition to conventional rehabilitation, the shock wave group received extracorporeal shock wave therapy twice a week and the combined treatment group received the shock waves during continuous static stretching. After 6 weeks of treatment all of the subjects were assessed using the Modified Ashworth Scale (MAS), the Fugl-Meyer Assessment (FMA) and Brunnstrom classification of their functional recovery stage.Results:Before treatment there was no significant difference among the three groups. After the 6 weeks of treatment the average triceps surae tension in all three groups had eased significantly. At that point the average MAS and FMA scores of the shock wave group and the combined treatment group were significantly better than those of the conventional group. The combined treatment group then showed significantly better therapeutic effect than the shock wave group.Conclusions:Applying extracorporeal shock waves during continuous static stretching can significantly improve the stretching′s ability to reduce spasticity and improve motor functioning, at least of the triceps surae. Combining shock waves with modern traction methods is recommended for clinical application.

ABSTRACT

Primary hypomagnesemia with secondary hypocalcemia(HSH) is a rare cause of hypoparathyroidism. This article presents a case of a 26-year-old male with recurrent generalized weakness and tetany, and a literature review of diagnosis and treatment of primary HSH. The biochemical tests revealed the patient had severe hypomagnesemia, mild hypocalcemia, hypokalemia, and hypoparathyroidism. Transient receptor potential melastatin-6(TRPM6) gene mutation were detected by gene test, which confirmed the diagnosis of primary HSH. The patient had been treated with long term oral magnesium supplementation, who remained asymptomatic during the follow-up. Primary HSH is a rare autosomal-recessive disorder caused by mutations in the TRPM6 gene which encoding a magnesium permeable channel expressed in the intestine and the kidney. The primary defect is impaired intestinal absorption of magnesium with secondary renal excretion, leading to a series of clinical symptoms. The treatment is mainly through lifelong magnesium supplementation.

ABSTRACT

Recombinant human interferon α2b(rhIFNα2b)is widely used as an antiviral therapy agent for the treatment of hepatitis B and hepatitis C.The current identification test for rhIFNα2b is complex.In this study,an anti-rhIFNα2b nanobody was discovered and used for the development of a rapid lateral flow strip for the identification of rhIFNα2b.RhIFNα2b was used to immunize an alpaca,which established a phage nanobody library.After five steps of enrichment,the nanobody I22,which specifically bound rhIFNα2b,was isolated and inserted into the prokaryotic expression vector pET28a.After subsequent purification,the physicochemical properties of the nanobody were determined.A semiquantitative detection and rapid identification assay of rhIFNα2b was developed using this novel nanobody.To develop a rapid test,the nanobody I22 was coupled with a colloidal gold to produce lateral-flow test strips.The developed rhIFNα2b detection assay had a limit of detection of 1 μg/mL.The isolation of I22 and successful construction of a lateral-flow immunochromatographic test strip demonstrated the feasibility of performing ligand-binding assays on a lateral-flow test strip using recombinant protein products.The principle of this novel assay is generally applicable for the rapid testing of other com-mercial products,with a great potential for routine use in detecting counterfeit recombinant protein products.

ABSTRACT

Objective:To explore the clinical characteristics, therapeutic efficacy and prognosis of congenital coronary artery fistula (CAF) in children.Methods:Clinical data of 71 pediatric patients diagnosed with congenital CAF at Department of Cardiology and Department of Cardiac Surgery, Shanghai Children′s Medical Center, Shanghai Jiao Tong University School of Medicine from January 2013 to June 2019 were retrospectively analyzed.The median age was 2.2 years (0.1-14.0 years), and the median body weight was 18.3 kg (3.2-55.8 kg), including 37 males (52.1%) and 34 females (47.9%). They were divided into the transcatheter closure group (30 cases) and surgical repair group (41 cases). The therapeutic effect and follow-up data of the 2 groups were compared by the Fisher′ s exact test. Results:Among the 71 congenital CAF children, 70 had heart murmurs, 2 had chest tightness after activity, and 5 were prone to recurrent respiratory tract infection.Transcatheter closure and surgical repair were successfully performed in 22/30 (73.3%) and 41/41 (100.0%) cases with a statistically significant difference ( P=0.001). However, in the surgical repair group, 1 (2.4%) case died after operation and 2(4.9%) needed further transcatheter closure due to large residual shunt during the follow-up period.At the last follow-up, there were 2 cases with minimal or small residual shunt in both groups ( P=0.567). There were 2/71(2.8%) cases suffering from postoperative thrombosis. Conclusions:Cardiac murmur is the main sign of congenital CAF in children, and some of them may have frequent respiratory tract infection due to increased lung blood caused by a large amount of shunt.A few children have chest tightness and chest pain due to myocardial ischemia caused by coronary steal.Both percutaneous closure and surgical repair are safe and effective with few complications.
