Meta-analysis of the efficacy of invisible orthodontic appliances for maxillary molar distalization in adult patients / 口腔疾病防治

Objective@#To evaluate the clinical efficacy of invisible orthodontic appliances without brackets for the distal movement of maxillary molars to improve the ability of orthodontists to predict treatment outcomes.@*Methods@#Web of Science, Cochrane Library, Embase, PubMed, Wanfang Database, CNKI Database, and VIP Database were searched for studies investigating the efficacy of invisible orthodontic appliances for distal movement of maxillary molars in adult patients and published from database inception to August 1, 2023. A total of three researchers screened the studies and evaluated their quality and conducted a meta-analysis of those that met quality standards.@*Results@#This study included 13 pre- and postcontrol trials with a total sample size of 281 patients. The meta-analysis revealed no significant differences in the sagittal or vertical parameters of the jawbone after treatment when compared with those before treatment (P>0.05). The displacement of the first molar was MD=-2.34, 95% CI (-2.83, -1.85); the displacement was MD=-0.95, 95% CI (-1.34, -0.56); and the inclination was MD=-2.51, 95% CI (-3.56, -1.46). There was a statistically significant difference in the change in sagittal, vertical, and axial tilt of the first molar before and after treatment. After treatment, the average adduction distance of the incisors was MD=-0.82, 95% CI (-1.54, -0.09), and the decrease in lip inclination was MD=-1.61, 95% CI (-2.86, -0.36); these values were significantly different from those before treatment (P<0.05).@*Conclusion@#Invisible orthodontic appliances can effectively move the upper molars in a distal direction and control the vertical position of the molars. When the molars move further away, there is some degree of compression and distal tilt movement, which is beneficial for patients with high angles. The sagittal movement of incisors is beneficial for improving the patient's profile.

Effects of short-term intensive insulin pump treatment on type 2 diabetes and its influencing factors / 中国临床药理学与治疗学

AIM: To observe the real world efficacy of continuous subcutaneous insulin infusion (CSII) with insulin pump in short-term intensive treatment of patients with type 2 diabetes (T2DM) and explore the influencing factors associated with efficacy. METHODS: A total of 369 hospitalized T2DM patients were treated with CSII short-term intensive therapy. Based on the blood glucose levels on the 5th day of treatment, they were divided into two groups, namely the qualified blood glucose control group and the non-qualified blood glucose control group. The differences of glucose metabolism, physiology, biochemistry and other indicators between the two groups were compared, and the influencing factors of insulin pump efficacy were analyzed by regression statistics. RESULTS: After 4 days of CSII short-term treatment, 225 patients (61%) achieved blood glucose control standards, while 144 patients (39%) did not achieve blood glucose control standards. Compared with the qualified blood glucose control group, the non-qualified blood glucose control group was older and with higher levels of total daily insulin dose per kilogram of body weight (TDD), fasting blood glucose (FBG), fasting insulin, fasting C-peptide, and insulin resistance index (HOMA-IR), while lower levels of blood phosphorus, insulin growth factor 1 (IGF1). In terms of biochemical indicators, there was no significant difference between the two groups as a whole, including blood lipid levels, liver function, and kidney function. The results of univariate regression and multivariate stepwise regression analysis showed that 2-hour postprandial insulin, TDD and blood phosphorus were the key factors influencing the efficacy of Insulin pump. Among them, qualified blood glucose control was positively correlated with blood phosphorus, and negatively correlated with 2-hour postprandial insulin and TDD. CONCLUSION: CSII with insulin pump is an ideal method for short-term intensive treatment of type 2 diabetes. In order to achieve a more satisfactory rate of qualified blood glucose control, more attention should be paid to the patient's blood phosphorus, 2-hour postprandial insulin and TDD in clinical use.

Evaluation of liposomal amphotericin B for the treatment of fungal keratitis in a tertiary eye care hospital

Purpose: To evaluate the efficacy of liposomal amphotericin B (L?AMB) for the treatment of fungal keratitis. Methods: Patients with fungal keratitis confirmed by potassium hydroxide (KOH) smear and/ or confocal microscopy were administered topical L?AMB and randomized into three groups treated with three different formulations. The medication was administered two hourly till clinical improvement was achieved, followed by six hourly till complete resolution. The outcome measures were time to clinical improvement, resolution of epithelial defect, stromal infiltrate, hypopyon, extent and density of corneal opacity, neovascularization, and best corrected visual acuity (BCVA) at 3 months. Results: Mean age of the patients was 46.6 ± 14.8 years, and trauma with vegetative matter was the most common predisposing factor. Aspergillus flavus (36%) was the most common fungus cultured, followed by Fusarium (23%). Mean time to clinical improvement, time to resolution of epithelial defect, mean time to resolution of infiltrate, and time to resolution of hypopyon were 3.45 ± 1.38, 25.35 ± 8.46, 37.97 ± 9.94, and 13.33 ± 4.90 days, respectively, and they were comparable among the three groups. There was a significant difference between treatment failure and success cases in terms of days of presentation (P < 0.01), size of the epithelial defect (P?value 0.04), and infiltrate size at presentation (P?value 0.04). At 3 months follow?up, no statistically significant difference was noted in BCVA and mean scar size among groups. Conclusion: L?AMB in a gel form is an effective antifungal agent that promotes the healing of fungal ulcers with notably least vascularization and better tolerance.

Advances in clinical and safety studies of phosphodiesterase 4 inhibitors / 药学学报

Phosphodiesterase 4 (PDE4) is an important member of the phosphodiesterase enzyme family that specifically catalyzes the hydrolysis of cyclic adenosine monophosphate (cAMP), activates the downstream phosphorylation cascade pathway by altering cAMP concentration, and is strongly associated with multiple diseases. Inhibition of PDE4 is clinically investigated as a therapeutic strategy in a broad range of disease areas, including respiratory system diseases, autoimmune disorders, central nervous system diseases, and dermatological conditions. However, the incidence of adverse reactions such as nausea and vomiting is relatively high in the marketed PDE4 inhibitors, which has stalled their clinical development. In this review, we provide an overview of the clinical progression and safety issues of the marketed PDE4 inhibitors. We also review the main causes underlying PDE4-mediated adverse effects by combining the structural analysis of the PDE4 protein, the mechanism of action of PDE4 inhibitors, and the related side effect mechanism research, aiming to provide a reference for the development of safe and effective PDE4 inhibitors.

Clinical Efficacy and Mechanism of Osteoking in Treatment of Knee Osteoarthritis Based on Real-world Data / 中国实验方剂学杂志

ObjectiveTo investigate the clinical efficacy and mechanisms of Osteoking in the treatment of knee osteoarthritis （KOA） in real-world practice， so as to provide a basis for the rational clinical use of Osteoking. MethodFrom the Osteoking for knee osteoarthritis case registration system， 638 KOA cases treated with Osteoking were selected and analyzed in SPSS 26.0. The clinical data were collected from 20 hospitals in China from May 2020 to December 2021. Descriptive analyses of patient age， gender， body mass index， course of treatment and other parameters were performed. The Mann-Whitney U test was performed to compare the visual analogue scale （VAS） and Western Ontario and McMaster universities arthritis index （WOMAC） scores before and after treatment. The integrative pharmacology-based research platform of traditional Chinese medicine （TCMIP） v2.0 was used for network analysis of the core targets of Osteoking in treating knee osteoarthritis. Furthermore， 20 KOA patients treated with Osteoking in the Third Affiliated Hospital of Beijing University of Chinese Medicine from October to December in 2022 were enrolled in the treatment group， and 20 healthy volunteers in the control group. The enzyme-linked immunosorbent assay was employed to measure the serum levels of related indicators to verify the prediction results. ResultA total of 638 KOA patients were treated with Osteoking， including 429 （67.24%） receiving Osteoking alone and 209 （32.76%） receiving Osteoking combined with other therapies. The female patients （415， 65.05%） were more than the male patients （223， 34.95%）. The patients showed the mean age of （63.48±13.51） years， mean body mass index of （24.09±2.98） kg·m-2， and mean course of treatment of （15.78±9.66） days. Most of the patients were rated as grades Ⅱ （46.24%） and Ⅲ （34.64%） in Kellgren-Lawrence （K-L） grading and in the relief stage （82.45%） in clinical staging. There was no significant correlation between clinical staging and K-L grading results. The cluster analysis identified three TCM syndromes： Qi stagnation and blood stasis， cold-dampness obstruction， and liver-kidney deficiency. The overall clinical efficacy evaluation showed that VAS score decreased from （6.01±0.85） scores before treatment to （2.54±1.73） scores after treatment （P<0.05）， and the WOMAC score decreased from （93.25±25.91） scores before treatment to （50.73±25.14） scores after treatment （P<0.05）. The network analysis predicted that Osteoking might regulate the transforming growth factor-beta （TGF-β）， tumor necrosis factor-alpha （TNF-α）， and nuclear factor-kappa B （NF-κB） signaling pathways to exert the therapeutic effect. The clinical trial showed elevated TGF-β1 level （P<0.01） and lowered NF-κB subunit RELA and tumor necrosis factor receptor superfamily， member 1A （TNFRSF1A） levels （P<0.05） after treatment. The synergistic effects of these changes provide a multidimensional and comprehensive therapeutic efficacy for KOA， alleviating the joint pain and limited mobility in patients. ConclusionOsteoking showed significant therapeutic efficacy in treating KOA. Osteoking may act on multiple pathways involved in cartilage metabolism and inflammation. The findings provide experimental evidence and theoretical support for elucidating the multi-target mechanism of Osteoking in treating KOA.

Effect of fluoxetine combined with Shugan Jieyu capsule in the treatment of patients with depression and its impact on heart rate variability / 四川精神卫生

BackgroundDepression is a kind of disease with relatively high suicide risk， which seriously affects the quality of life of patients and their families， and brings a great burden to society. Antidepressants in western medicine are effective， but the improvement of depressive symptoms is relatively limited by single use， and the combination of two antidepressants may increase the risk of adverse reactions in patients. The rational use of Chinese patent medicine and western medicine may play a complementary role， and the safety of Chinese patent medicine is high. ObjectiveTo explore the early clinical efficacy of fluoxetine combined with Shugan Jieyu capsule in the treatment of depression， and to compare the differences in efficacy， safety and influence on heart rate variability between fluoxetine combined with Shugan Jieyu capsule and fluoxetine alone， so as to provide references for clinical medication of depression patients. MethodsFrom December 2015 to June 2016， 64 patients who met the diagnostic criteria of depression in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） who were hospitalized in the Second Affiliated Hospital of Xinxiang Medical University were selected as the research objects， and were randomly divided into the combined medication group and the fluoxetine group with 32 patients in each group. Patients in both groups were treated with fluoxetine， while patients in the combined medication group were treated with Shugan Jieyu capsule on this basis. Patients in both groups were assessed with Hamilton Depression Scale-24 item （HAMD-24）， Hamilton Anxiety Scale （HAMA） and Heart Rate Variability （HRV） before treatment， and were assessed with HAMD-24 and Treatment Emergent Symptom Scale （TESS） at the end of the 2nd， 4th and 6th week of treatment， and HRV was analyzed again at the end of the 6th week of treatment. ResultsThe study ultimately included 60 patients with depression， with 30 cases in the combination therapy group and 30 cases in the fluoxetine group. At the end of the 2nd， 4th and 6th week of treatment， the HAMD-24 score of the combined drug group was lower than that of the fluoxetine group （t=-2.677， -3.960， -4.432， P<0.05 or 0.01）. Compared with before treatment， the 24-hour mean standard deviation of normal RR intervals （SDNN）， normal low frequency （nLF） and normal high frequency （nHF） in the combined treatment group were higher at the end of the 6th week （t=-73.970， -31.878， -38.721， P<0.01）， but significant lower in LF/HF （t=3.525， P<0.01）. At the end of the 6th week of treatment， the total effective rate of the combined treatment group was higher than that of fluoxetine group， and the difference was statistically significant （86.67% vs. 70.00%， χ2=18.764， P<0.01）. At the 2nd， 4th and 6th week of treatment， there was no significant difference in the number of adverse reactions between the two groups （P>0.05）. ConclusionCompared with fluoxetine alone， Shugan Jieyu capsule combined with fluoxetine may be better in clinical efficacy and improvement of heart rate variability in patients with depression， without increasing adverse reactions.

Perioperative and long-term outcomes of laparoscopic versus open hepatectomy for hepatocellular carcinoma at specific sites of liver / 中华肝胆外科杂志

Objective:To compare the clinical efficacy of laparoscopic and open surgery in the treatment of hepatocellular carcinoma (HCC) at specific sites of liver.Methods:Data of patients with HCC undergoing hepatectomy in Mengchao Hepatobiliary Hospital of Fujian Medical University from September 2014 to May 2019 were retrospective analyzed. A total of 205 patients were enrolled, including 174 males and 31 females, aged (56.7±11.3) years. According to the surgical methods, patients were divided into laparoscopic group ( n=105) and open group ( n=100). The Child-Pugh score, maximum tumor diameter, tumor location, intraoperative blood loss, postoperative complication rate, liver function(glutamate transaminase, alanine transaminase, etc.) and length of hospital stay were compared between the two groups. Postoperative survival and recurrence were followed up. Survival curves and rates were analyzed by Kaplan-Meier and log-rank test. Results:There were no significant differences in Child-Pugh score, maximum tumor diameter, tumor location between the two groups. Compared to the open group, the laparoscopic group had a decreased blood loss [100 (50, 200) ml vs 150 (100, 200) ml], a lower incidence of postoperative complications[7.6%(8/105) vs 17.0%(17/100)], and a shorter hospital stay [(8.6±1.9) days vs (13.0±3.4) days](all P<0.05). The postoperative glutamate transaminase and alanine transaminase levels were lower in the laparoscopic group than those in the open group. The 1, 3, 5-year overall survival and recurrence-free survival were not significantly different between the two groups (χ 2=0.56, 0.21, P=0.456, 0.648). Conclusion:Laparoscopic surgery in the treatment of HCC at specific sites of liver is a safe, feasible and effective procedure.

According to mRECIST, objective response rate was 90.0% (18/20) and the disease control rate was 100.0% (20/20) after 2 cycles of treatment. Following the treatment, 12 patients (60.0%) received liver tumor resection, and all of them achieved R 0 resection, 2 patients (10.0%) received radiotherapy, 3 patients (15.0%) stopped drug treatment for surgery, 2 patients (10.0%) refused surgery, and 1 patient (5.0%) died of multiple organ failure caused by immune hepatitis. According to pathological results, 3 patients (25.0%, 3/12) achieved pathological complete response, and 4 patients (33.3%, 4/12) achieved major pathological response. In the safety evaluation, the overall incidence of adverse events was 100.0% (20/20). Seven patients (35.0%) had grade 3 adverse events and 1 patient (5.0%) died of multiple organ failure due to immune hepatitis (grade 5). Grade 1-3 adverse events could be relieved after symptomatic treatment. Conclusion:The triple combination therapy of FOLFOX-HAIC combined with immune and targeted therapy is safe and has high objective response rate and disease control rate, which could be a new strategy for the neoadjuvant treatment of hepatocellular carcinoma.

Effect of continuous renal replacement therapy on plasma concentration, clinical efficacy and safety of colistin sulfate / 中华危重病急救医学

Objective:To investigate the effects of continuous renal replacement therapy (CRRT) on plasma concentration, clinical efficacy and safety of colistin sulfate.Methods:Clinical data of patients received with colistin sulfate were retrospectively analyzed from our group's previous clinical registration study, which was a prospective, multicenter observation study on the efficacy and pharmacokinetic characteristics of colistin sulfate in patients with severe infection in intensive care unit (ICU). According to whether patients received blood purification treatment, they were divided into CRRT group and non-CRRT group. Baseline data (gender, age, whether complicated with diabetes, chronic nervous system disease, etc), general data (infection of pathogens and sites, steady-state trough concentration, steady-state peak concentration, clinical efficacy, 28-day all-cause mortality, etc) and adverse event (renal injury, nervous system, skin pigmentation, etc) were collected from the two groups.Results:A total of 90 patients were enrolled, including 22 patients in the CRRT group and 68 patients in the non-CRRT group. ① There was no significant difference in gender, age, basic diseases, liver function, infection of pathogens and sites, colistin sulfate dose between the two groups. Compared with the non-CRRT group, the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) were higher in the CRRT group [APACHE Ⅱ: 21.77±8.26 vs. 18.01±6.34, P < 0.05; SOFA: 8.5 (7.8, 11.0) vs. 6.0 (4.0, 9.0), P < 0.01], serum creatinine level was higher [μmol/L: 162.0 (119.5, 210.5) vs. 72.0 (52.0, 117.0), P < 0.01]. ② Plasma concentration: there was no significant difference in steady-state trough concentration between CRRT group and non-CRRT group (mg/L: 0.58±0.30 vs. 0.64±0.25, P = 0.328), nor was there significant difference in steady-state peak concentration (mg/L: 1.02±0.37 vs. 1.18±0.45, P = 0.133). ③ Clinical efficacy: there was no significant difference in clinical response rate between CRRT group and non-CRRT group [68.2% (15/22) vs. 80.9% (55/68), P = 0.213]. ④ Safety: acute kidney injury occurred in 2 patients (2.9%) in the non-CRRT group. No obvious neurological symptoms and skin pigmentation were found in the two groups. Conclusions:CRRT had little effect on the elimination of colistin sulfate. Routine blood concentration monitoring (TDM) is warranted in patients received with CRRT.

Meta-analysis of the clinical efficacy of compound α-ketoacid tablets combined with low-protein diet in diabetic kidney disease / 中华临床营养杂志

Objective:To systematically evaluate the clinical efficacy of compound α-ketoacid tablets in the treatment of diabetic kidney disease (DKD).Methods:CNKI, Wanfang database, EMBASE, PubMed and Cochrane Library database were searched for eligible records published from the establishment of individual database to November 13 th, 2022. The quality of the included studies were assessed, data were extracted, and meta-analysis was conducted using RevMan5.3. Results:A total of 26 randomized controlled trials were included, with a total of 2 790 DKD patients (1 465 in the experimental group and 1 325 in the control group). Multiple parameters were significantly improved in the experimental group compared with the control group, including 24-hour urinary protein, blood creatinine, urea nitrogen, nutritional index, oxidative stress level, fasting blood glucose, glycated hemoglobin, homocysteine, HGF, VEGF, TGF-β1, and systolic blood pressure.Conclusions:Limited low-quality evidence showed that compound α-ketoacid tablets combined with low-protein diet may be related to the improved 24-hour urinary protein, renal function, and glucose metabolism in patients with DKD. Due to the lack of randomized controlled trials designed for respective stages of DKD, the inclusion criteria of our study were relatively general, possibly leading to the lack of pertinence of the results. Some indicators showed apparent heterogeneity among different groups, and more high-quality multi-center studies with large sample sizes are still needed to verify our findings.

Clinical efficacy of early versus delayed open reduction and internal fixation in the treatment of tibial pilon fracture / 中国基层医药

Objective:To investigate the clinical efficacy of early versus delayed open reduction and internal fixation in the treatment of tibial pilon fracture. Methods:Sixty patients with tibial pilon fractures admitted to Zhejiang Veteran Hospital from May 2018 to May 2021 were included in this study. They were randomly divided into a control group and a study group ( n = 30/group) using the coin-tossing method. Patients in the control group underwent early reduction and internal fixation within 3 days after injury. Patients in the study group underwent delayed reduction and internal fixation during 7-14 days after injury. The time to bone fracture healing and the time to independent weight-bearing walking were recorded. At 3 and 6 months after surgery, the American Orthopedic Foot and Ankle Society score, Visual Analogue Scale score, clinical efficacy, and incidence of complications were compared between the two groups. Results:The time to bone fracture healing and the time to independent weight-bearing walking in the study group were (8.23 ± 0.63) weeks and (11.77 ± 0.82) weeks, respectively, which were significantly shorter than (9.57 ± 0.86) weeks and (13.40 ± 0.93) weeks in the control group ( t = 6.87, 7.21, both P < 0.001). At 3 months after surgery, American Orthopedic Foot and Ankle Society score in the study group was significantly higher than that in the control group, and the Visual Analogue Scale score in the study group was significantly lower than that in the control group ( t = 6.69, 5.16, both P < 0.001). Overall excellent and good rate of clinical efficacy in the study group was significantly higher than that in the control group (86.6% vs. 63.3%, χ2 = 4.35, P = 0.037). At 6 months after surgery, there were no significant differences in American Orthopedic Foot and Ankle Society score and Visual Analogue Scale score between the two groups ( t = 0.96, 1.12, P = 0.339, 0.267). At 6 months after surgery, there was no significant difference in the overall excellent and good rate of clinical efficacy between the study and control groups (96.6% vs. 90.0%, χ2 = 0.26, P = 0.605). The incidence of complications in the study group was significantly lower than that in the control group (3.3% vs. 26.6%, χ2 = 4.70, P = 0.030). Conclusion:Delayed open reduction and internal fixation after reducing injury to the soft tissue of the affected limbs can effectively shorten the rehabilitation cycle of tibial pilon fracture, increase short-term efficacy, and decrease the risk of postoperative complications.

Efficacy and safety of dapagliflozin combined with metformin in treatment of type 2 diabetes mellitus / 中国医师进修杂志

Objective:To analyze the efficacy and safety of dapagliflozin combined with metformin in the treatment of type 2 diabetes.Methods:A prospective research method was adopted. A total of 60 patients with type 2 diabetes who were treated in Huainan Chaoyang Hospital from January 2019 to December 2021 were collected as research objects, and the above patients were divided into the observation group (30 cases) and the control group (30 cases) according to the random number table method. After admission, they were treated with oral metformin sustained-release tablets combined with exercise and diet control. On this basis, the observation group was treated with dapagliflozin, while the control group was treated with glimepiride. The blood glucose-related indexes after 3 months of treatment, blood lipid indexes after 1 month of treatment, and adverse reactions were compared between the two groups of patients.Results:After 3 months of treatment, the fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h PBG) and glycosylated hemoglobin (HbA 1c) of the two groups were significantly lower than those before treatment, observation group: (6.60 ± 1.01) mmol/L vs. (7.76 ± 1.82) mmol/L, (10.43 ± 2.74) mmol/L vs. (14.05 ± 3.84) mmol/L, (5.90 ± 1.56)% vs. (8.46 ± 2.07)%; control group: (6.77 ± 0.95) mmol/L vs. (7.82 ± 1.38) mmol/L, (10.17 ± 2.23) mmol/L vs. (14.01 ± 2.63) mmol/L, (6.14 ± 1.51)% vs. (8.73 ± 1.58)% ( P<0.05), but there was no difference in FBG, 2 h PBG and HbA 1c between the two groups ( P>0.05). The total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in the observation group were significantly lower than those in the control group: (5.02 ± 0.98) mmol/L vs. (5.71 ± 0.77) mmol/L, (2.81 ± 0.69) mmol/L vs. (3.39 ± 0.87) mmol/L ( P<0.05). There was no difference in adverse reactions ( P>0.05). Conclusions:For patients with type 2 diabetes mellitus, on the basis of metformin sustained-release therapy, whether combined with dapagliflozin or glimepiride therapy has good hypoglycemic effect, but dapagliflozin has more advantages in improving blood lipids.
