BACKGROUND:Stand-alone oblique lateral interbody fusion has a high rate of complications of fusion segment sink.Oblique lateral interbody fusion with posterior fixation can provide stable support,but intraoperative position changes and double incisions weaken the advantages of this technique.Oblique lateral interbody fusion combined with lateral plate fixation can achieve one-stage decompression in the same incision,while the lateral internal fixation provides stable support. OBJECTIVE:To analyze the short-term efficacy of oblique lateral interbody fusion combined with lateral plate fixation in the treatment of single-level lumbar degenerative disease. METHODS:The clinical data of 34 patients with single-level lumbar degenerative disease treated with oblique lateral interbody fusion combined with lateral plate fixation were collected from May 2020 to October 2022.Among them,14 were males and 20 were females aged from 41 to 72 years at the mean age of(58.6±9.9)years.There were 11 cases of lumbar spondylolisthesis(Ⅰ°),7 cases of lumbar disc herniation with segmental instability,and 16 cases of lumbar spinal stenosis.Operation time,blood loss,and complications were recorded.Visual analog scale scores of lumbago,radiative pain of both lower limbs,and Oswestry disability index scores were evaluated before surgery,3 months after surgery,and the last follow-up.Dural sac cross-sectional area,intervertebral height,and intervertebral fusion were measured and observed. RESULTS AND CONCLUSION:(1)The 34 patients were followed up for 14-36 months,with an average of(21.3±5.2)months.(2)The operation time ranged from 50 to 92 minutes,with an average of(68.5±11.1)minutes.Intraoperative blood loss was 50-170 mL,with an average of(71.6±25.3)mL.(3)Compared with the preoperative results,the visual analog scale scores and Oswestry disability index scores were significantly decreased at 3 months after surgery and at the last follow-up(P<0.001),and the maximum Oswestry disability index scores were improved by nearly 50％.(4)Bone fusion was achieved in all patients during half-year follow-up.The overall complication rate was 21％(7/34),including 1 case of plate displacement,3 cases of cage subsidence,1 case of psoas weakness,and 2 cases of anterior thigh pain.(5)It is concluded that oblique lateral interbody fusion combined with lateral plate fixation for the treatment of lumbar degenerative diseases has the characteristics of less blood loss,short operation time,rapid postoperative recovery,and significant short-term clinical efficacy with the stable support to a certain extent.The long-term curative effect needs further follow-up observation.

This study aimed to evaluate the cost-effectiveness of Chaiyin Granules compared with Oseltamivir Phosphate Capsules in the treatment of influenza(exogenous wind-heat syndrome). Based on a randomized, double-blind, positive drug parallel control clinical trial, this study evaluated the pharmacoeconomics of Chaiyin Granules with cost-effectiveness analysis method. A total of 116 patients with influenza from eight hospitals(grade Ⅱ level A above) in 6 cities were selected in this study, including 78 cases in the experimental group with Chaiyin Granules and Oseltamivir Phosphate Capsules placebo, and 38 cases in the control group with Oseltamivir Phosphate Capsules and Chaiyin Granules placebo. The total cost of this study included direct medical cost, direct non-medical cost, and indirect cost. The remission time of clinical symptoms, cure time/cure rate, antipyretic onset time/complete antipyretic time, viral nucleic acid negative rate, and traditional Chinese medicine(TCM) syndrome curative effect were selected as the effect indicators for cost-effectiveness analysis. Four-quadrant diagram was used to estimate the incremental cost-effectiveness ratio. The results showed that Chaiyin Granules were not inferior to Oseltamivir Phosphate Capsules in the remission time of clinical symptoms of influenza(3.1 d vs 2.9 d, P=0.360, non-inferiority margin was 0.5 d). Compared with Oseltamivir Phosphate Capsules, Chaiyin Granules would delay the remission time of clinic symptoms of influenza for 1 d, but could save 213.9 yuan. 1 d delay in cure time could save 149.3 yuan; 1% reduction in the cure rate could save 8.2 yuan; 1 d delay in antipyretic onset time could save 295.4 yuan; 1 d delay in complete antipyretic time could save 114.3 yuan; 1% reduction in the 5-day cure rate of TCM syndrome could save 19.2 yuan. Different from other indicators, there was no statistically significant difference between two groups in the effect of negative conversion rate of viral nucleic acid, but the cost was lower and the effect was superior, and the pharmacoeconomics was not different from that of Oseltamivir Phosphate Capsules in the field of influenza treatment.

Objective To verify the biomechanical stability of oblique lateral interbody fusion ( OLIF) combinedwith different fixation methods for treating degenerative lumbar scoliosis (DLS) by three-dimensional (3D) finite element analysis. Methods The L1-S1 3D finite element DLS model ( Model 1) was established, and then the OLIF (L2-5) at 3 contiguous levels of fusion and its combination with different internal fixation methods were simulated, namely, stand-alone OLIF model ( Model 2), vertebral screw fixation model ( Model 3), unilateral pedicle screw fixation model (Model 4) and bilateral pedicle screw fixation model (Model 5) were established,respectively. Under upright, flexion, extension, lateral bending and axial rotation states, range of motion (ROM) of fusion segments, as well as cage stress, internal fixation stress, and stress distribution were recorded and analyzed. Results Under six motion states, the overall ROM of fusion segments in Models 2-5 was smaller than that of Model 1. Compared with Model 1, the overall ROM reduction of Model 3 and Model 4 was larger than that of Model 2 and smaller than that of Model 5. Under flexion and extension, the overall ROM reduction of Model 4 and Model 5 was basically equal. Under left and right lateral bending, the overall ROM reduction of Model 3 and Model 5 was basically equal. Under all motion states, the peak stress of Model 3 and Model 4 fusion cage was larger than that of Model 5 and smaller than that of Model 2. The peak stresses of L2-3, L3-4 and L4-5 fusion cages in Model 3 increased by 5. 52% , 10. 96% and 7. 99% respectively compared with Model 5 under left lateral bending, and the peak stresses of L2-3, L3-4 and L4-5 fusion cages in Model 4 increased by 8. 70% , 7. 00% and 6. 99% respectively under flexion. Under all motion states, the peak stress of screw rod in Model 5 was smaller than that of Model 3 and Model 4, and the peak stresses of screw rod in Models 3-5 were the smallest in upright state. Conclusions The OLIF with unilateral pedicle screw fixation or vertebral screw fixation can provide favorable biomechanical stability of the fusion segment. The results provide some references for clinical application of OLIF technology in the treatment of DLS.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective: To investigate the safety and efficacy of ultrafiltration on diuretic sensitivity in heart failure patients with reduced ejection fraction and diuretic resistance. Methods: This was a single-center randomized controlled trial. A total of 148 heart failure patients with reduced ejection fraction admitted to the Hospital of Traditional Chinese Medicine of Xinjiang Uygur Autonomous Region from June 2010 to June 2020 were enrolled in this study, and these patients were randomly divided (ratio 1:1) into the ultrafiltration group (n=74) and the control group (n=74). All patients were treated with diuretics, cardiotonic, vasodilator and other comprehensive drugs according to relevant guidelines. After grouping, the patients in the control group were treated with standard treatment plan, while patients in the ultrafiltration group were treated with ultrafiltration on top of standard therapy. Diuretic drugs were discontinued during ultrafiltration, and intravenously furosemide (40 mg) was given immediately and 24 hours after the end of ultrafiltration. Clinical data including gender, age, complicated diseases, New York Heart Association (NYHA) function classification, etc. were collected. Effectiveness indicators include urine volume (the first 12-hour and 24-hour urine volume and the second 24-hour urine volume after using diuretic), body weight and dyspnea severity score. Safety indicators include systolic blood pressure, serum creatinine, serum Na⁺ concentration, blood K⁺ concentration and the number of deaths before and after intervention. Results: Two patients in the control group died due to worsening heart failure after randomization and were excluded in this study, 146 patients were finally analyzed (72 patients in the control group and 74 patients in the ultrafiltration group). There were 93 males, and the age was (68.3±11.2) years. There was no significant difference between patients in the ultrafiltration group and the control group in gender, age, body weight, course of disease, dyspnea severity score, NYHA function classification Ⅲ/Ⅳ, the proportion of patients with severe edema of both lower limbs, the proportion of patients with complicated diseases, and basic medication (all P>0.05). After using diuretics, the urine volume of the first 12-hour and 24-hour and the second 24-hour were significantly higher in the ultrafiltration group than in the control group (all P<0.05). Body weight decreased significantly after ultrafiltration treatment as compared with that before intervention in the ultrafiltration group (P<0.05). Compared with the control group, the dyspnea severity score was significantly improved in the ultrafiltration group (P<0.05). There was no significant difference in systolic blood pressure, serum creatinine, serum Na⁺ concentration, blood K⁺ concentration of patients between ultrafiltration group and control group before and after intervention (all P>0.05). During the clinical diagnosis and treatment, 2 male patients in the control group died, and the cause of death was aggravation of basic diseases complicated with acute heart failure and cardiogenic shock. There was no death in the ultrafiltration group, and there were no obvious clinical adverse events during and after ultrafiltration. Conclusion: Ultrafiltration therapy is safe and can improve diuretic sensitivity in heart failure patients with reduced ejection fraction and diuretic resistance.

De-etiolation consists of a series of developmental and physiological changes that a plant undergoes in response to light. During this process light, an important environmental signal, trig-gers the inhibition of mesocotyl elongation and the production of photosynthetically active chloro-plasts, and etiolated leaves transition from the'sink"stage to the'source"stage. De-etiolation has been extensively studied in maize (Zea mays L.). However, little is known about how this transition is regulated. In this study, we described a quantitative proteomic and phosphoproteomic atlas of the de-etiolation process in maize. We identified 16,420 proteins in proteome, among which 14,168 pro-teins were quantified. In addition, 8746 phosphorylation sites within 3110 proteins were identified. From the combined proteomic and phosphoproteomic data, we identified a total of 17,436 proteins. Only 7.0％(998/14,168) of proteins significantly changed in abundance during de-etiolation. In con-trast, 26.6％ of phosphorylated proteins exhibited significant changes in phosphorylation level;these included proteins involved in gene expression and homeostatic pathways and rate-limiting enzymes involved in photosynthetic light and carbon reactions. Based on phosphoproteomic anal-ysis, 34.0％(1057/3110) of phosphorylated proteins identified in this study contained more than 2phosphorylation sites, and 37 proteins contained more than 16 phosphorylation sites, indicating that multi-phosphorylation is ubiquitous during the de-etiolation process. Our results suggest that plants might preferentially regulate the level of posttranslational modifications (PTMs) rather than protein abundance for adapting to changing environments. The study of PTMs could thus better reveal the regulation of de-etiolation.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP &ge; 140 mmHg and/or diastolic BP &ge; 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.
