BACKGROUND:Epidemiologic studies have shown a correlation between type 2 diabetes mellitus and bone mineral density,but the causal association between the two and whether it is age-related remains unknown. OBJECTIVE:To study the correlation between type 2 diabetes mellitus and whole body bone mineral density at unspecified age and at all ages based on the Mendelian randomization technique. METHODS:The genome-wide association study(GWAS)data of type 2 diabetes mellitus and bone mineral density at all ages were selected from the IEU GWAS database of the University of Bristol.The exposure data were single nucleotide polymorphisms with significant correlation with type 2 diabetes mellitus as instrumental variables,and bone mineral density at all ages was selected as the outcome variable.Two-sample Mendelian randomization analysis of type 2 diabetes mellitus and bone mineral density was performed using inverse variance weighted method,weighted median estimator,and MR-Egger regression.The βvalue was used to evaluate the causal relationship between type 2 diabetes mellitus and bone mineral density at all ages. RESULTS AND CONCLUSION:A total of 118 single nucleotide polymorphisms were extracted from the GWAS summary data as instrumental variables.The MR-Egger regression results showed that there was no horizontal pleiotropy,but there was heterogeneity.Therefore,this study was based on the inverse variance weighted results.Inverse variance weighted results showed that type 2 diabetes mellitus may be a potential protective factor for bone mineral density and is associated with age:age-unspecified bone mineral density[β=0.038,95%confidence interval(CI):1.01-1.07,P=0.002],bone mineral density over 60 years old(β=0.052,95%CI:1.01-1.09,P=0.027),bone mineral density between 45-60 years old(β=0.049,95%CI:1.01-1.09,P=0.009),bone mineral density between 30-45 years old(β=0.033,95%CI:0.99-1.07,P=0.127).bone mineral density of 15-30 years old(β=0.025,95%CI:0.95-1.10,P=0.506),bone mineral density of 0-15 years old(β=0.006,95%CI:0.96-1.04,P=0.716).Similar results were obtained from the MR-Egger regression and weighted median estimator analyses.These findings indicate that type 2 diabetes mellitus may be one of the protective factors of bone mineral density,and there is a correlation with age.

Objective To explore the prognostic impact and clinical application value of therapeutic plasma exchange(TPE)intervention timing and liver injury periodization in patients with exertional heat stroke(EHS).Methods Data of 127 EHS patients from the First Medical Center of the General Hospital of the People′s Liberation Army from January 2011 to December 2023 were collected,then divided into the death group and the survival group based on therapeutic outcomes and into 5 stages according to the dynamic changes of ALT,AST,TBIL and DBIL.According to propensity score matching analysis,11 patients in the survival group and 12 patients in the death group were included in the statistical analysis,and 20 of them were treated with TPE.The changes in indicators and clinical outcomes before and after TPE were observed,in order to evaluate the impact of intervention timing on prognosis.Results Among the 23 patients,14 had no liver injury or could progress to the repair phase,resulting in 3 deaths(with the mortality rate of 21.43%),while 9 patients failed to pro-gress to the repair phase,resulting in 9 deaths(with the mortality rate of 100%),with significant differences(P＜0.05).The mortality rate of the first TPE intervention before the third stage of liver injury was 23.08%(3/13),while that of interven-tion after reaching or exceeding the third stage was 85.71%(6/7),and the difference was statistically significant(P＜0.05).Conclusion TPE should be executed actively in EHS patients combined with liver injury before the third phase to lock its pathological and physiological processes,thereby improving prognosis and reducing mortality.

Objective:To investigate the application value of laparoscopic-assisted total liver transplantation.Methods:The retrospective and descriptive study was conducted. The clinical data of 9 pairs of donors and recipients who underwent laparoscopic-assisted total liver transplanta-tion in People′s Hospital of Guangxi Zhuang Autonomous Region from January to April 2024 were collected. Of the donors, there were 8 males and 1 female, aged (39±18)years and with body mass index (BMI) of (20±4)kg/m 2. Of the recipients, there were 7 males and 2 females, aged (41±13)years and with BMI of (24±4)kg/m 2. Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers. Results:(1) Surgical conditions. Of the 9 recipients, 7 recipients underwent laparoscopic-assisted total liver transplantation successfully, 1 recipient with severe portal hypertension converted to open surgery with reverse L-shaped incision due to the hemorrhage during the dissection of the first hepatic portal after completing liver mobilization under laparoscopy, and 1 recipient underwent trans-umbilical extension incision through the middle of the epigastric region due to the limited space for operation in the implantation of the donor liver. The total operation time for 7 recipients who successfully underwent laparoscopic-assisted total liver transplantation was (648±31)minutes, with a time of anhepatic phase of (57±5)minutes, the volume of intraoperative blood loss of (1 322±627)mL, the donor liver mass of (1 195±232)g, and the ratio of donor liver mass to recipient body mass of 1.86%±0.42%. The operation time for laparoscopic liver dissection and porta hepatis dissection in 8 recipients during surgery was (212±35)minutes. (2) Postoperative conditions. All 9 recipients recovered smoothly after surgery, without any vascular or biliary related complications, and the surgical incision recovered well. The duration of postoperative hospital stay of 7 recipients who successfully underwent laparoscopic-assisted total liver transplantation was (14.2±2.0)days. (3) Follow-up. All 9 recipients were followed up for 3 months after surgery. During the follow-up period, there was no vascular or bile duct related complication.Conclusion:Laparoscopic-assisted total liver transplantation can be applied to recipients who meet surgical conditions and achieve good short-term clinical efficacy.

Objective:To study the effect of different sufentanil doses on hemodynamics and interleukin (IL)-6 in children with ventricular septal defect repair (VSDR).Methods:A total of 96 children who underwent VSDR surgery in Three Gorges Hospital Affiliated to Chongqing University from January 2016 to June 2019 were selected. Children with VSDR were enrolled and divided into A group (0.8 μg/kg), B group (1.0 μg/kg) and C group (1.1 μg/kg) according their sufentanil doses. The heart rate (HR), contraction pressure (SBP), the brain electric double frequency index (BIS) and IL-6 in different time were studied and compared. The adverse cardiovascular events and other indicators were studied and compared.Results:At t 2 to t 6, there were significant difference among the three groups in HR, A group: (104.62 ± 10.58), (128.73 ± 13.29), (127.59 ± 13.53), (125.62 ± 12.60) and (118.49 ± 11.62) times/min, B group: (100.27 ± 10.11), (119.33 ± 12.62), (116.57 ± 11.40), (113.57 ± 11.94) and (113.37 ± 11.46) times/min, C group: (87.92 ± 8.87), (98.62 ± 9.69), (94.42 ± 9.38), (88.72 ± 8.62) and (89.36 ± 9.17) times/min; SBP, A group: (79.54 ± 7.59), (102.75 ± 10.62), (90.62 ± 9.52), (85.19 ± 8.62) and (83.98 ± 8.62) mmHg (1 mmHg = 0.133 kPa), B group: (76.74 ± 7.28), (90.45 ± 9.57), (87.38 ± 8.51), (84.72 ± 8.50) and (83.77 ± 8.58) mmHg, C group: (70.62 ± 7.27), (75.62 ± 7.83), (72.69 ± 7.80), (71.28 ± 7.43) and (71.39 ±7.16) mmHg, P<0.05. At t 2 to t 4, there were significant differences among the three groups in BIS, A group: 48.64 ± 5.03, 53.58 ± 5.71 and 59.61 ± 5.87, B group: 48.79 ± 5.12, 50.23 ± 5.24 and 57.75 ± 5.66, C group: 43.59 ± 4.62, 50.31 ± 5.34, 55.26 ± 5.53, P<0.05. At T 2 to T 6, there was a significant difference among the three groups in IL-6, A group: (0.41 ± 0.06), (0.49 ± 0.11), (0.53 ± 0.13), (0.82 ± 0.17) and (0.61 ± 0.15) μg/L, B group: (0.38 ± 0.05), (0.42 ± 0.08), (0.46 ± 0.09), (0.75 ± 0.14) and (0.53 ± 0.12) μg/L, C group: (0.35 ± 0.05), (0.40 ± 0.06), (0.43 ± 0.07), (0.72 ± 0.12) and (0.51 ± 0.11) μg/L, P<0.05. Compared with that in A group and C group, HR, SBP and BIS in B group had relatively low volatility. At T 2 to T 6, IL-6 level in A group was significantly higher than that in B group and C group, and there was a statistically significant difference ( P<0.05). The incidence of cardiovascular adverse events in A group and C group was significantly higher than that in B group, and there was statistical difference ( P<0.05). Conclusions:1.0 μg/kg sufentanil can have less effect on hemodynamics and IL-6 in children with VSDR with less adverse cardiovascular events and other indicators.

The E class MADS-box genes SEPALLATA (SEP)-like play critical roles in angiosperm reproductive growth, especially in floral organ differentiation. To analyze the sequence characteristics and spatio-temporal expression patterns of E-function MADS-box SEP-like genes during kale (Brassica oleracea L. var. acephala) flower development, BroaSEP1/2/3 (GenBank No. KC967957, KC967958, KC967960) homologues, three kale SEP MADS-box gene, were isolated from the kale variety 'Fourteen Line' using Rapid amplification of cDNA ends (RACE). Sequence and phylogenetic analysis indicated that these three SEP genes had a high degree of identity with SEP1, SEP2, SEP3 from Brassica oleracea var. oleracea, Brassica rapa, Raphanus sativus and Brassica napus, respectively. Alignment of the predicted amino acid sequences from these genes, along with previously published subfamily members, demonstrated that these genes comprise four regions of the typical MIKC-type MADS-box proteins: the MADS domain, intervening (I) domain and keratin-like (K) domain, and the C-terminal domain SEPⅠ and SEP Ⅱ motif. The longest open reading frame deduced from the cDNA sequences of BroaSEP1, BroaSEP2, and BroaSEP3 appeared to be 801 bp, 759 bp, 753 bp in length, respectively, which encoded proteins of 266, 252, and 250 amino acids respectively. Expression analyses using semi-quantitative RT-PCR and quantitative real-time PCR indicate that BroaSEP1/2/3 are specifically expressed in floral buds of kale during flower development process. The expression levels of the three genes are very different at different developmental stages, also in wild type, mutant flower with increased petals, and mutant flower with decreased petals. These different patterns of gene expression maybe cause the flowers to increase or decrease the petal number.

Objective:To compare the clinical outcomes between modified percutaneous kyphoplasty (PKP) and conventional PKP in the treatment of Kümmell disease.Methods:A retrospective cohort study was conducted of the 57 patients with single level kummell disease who had undergone PKP between January 2015 and December 2017 at Department of Spinal Surgery, Jiangmen Hospital Affiliated to Sun Yat-sen Uni-versity.Of them, 36 received modified PKP and 21 conventional PKP.In the modified PKP group, there were 24 males and 12 females with an age of 73.9 years±9.4 years and a course of disease of 2.2 months±1.5 months; the disease was located at a thorocic vertebra in 20 cases and at a lumbar vertebra in 16.In the conventional PKP group, there were 15 males and 6 females with an age of 72.6 years±11.9 years and a course of disease of 1.8 months±1.1 months; the disease was located at a thorocic vertebra in 10 cases and at a lumbar vertebra in 11.The 2 groups were compared in terms of operation time, bone cement volume, cement leakage, visual analogue scale (VAS), Oswestry disability index (ODI), anterior and middle heights and cobb angle of injured vertebra at postoperative 3 days, 1 and 3 months, and final follow-up.Results:There were no significant differences in the general clinical data between the 2 groups, showing compatibility between groups ( P>0.05).All the operations were accomplished uneventfully with no such serious complications as spinal cord nerve injury, wound infection, pulmonary embolism, bone cement poisoning reaction or death. There was no significant difference between the 2 groups in operation time or bone cement volume ( P>0.05).The rate of cement leakage in the modified PKP group [33.3%(9/27)] was significantly lower than that [52.4%(11/21)] in the conventional PKP group ( P<0.05).There were no significant differences be-tween the 2 groups in VAS, ODI, anterior or middle height of injured vertebra or cobb angle at postoperative 3 days or one month ( P>0.05), but the postoperative values were improved compared to the preoperative ones.At postoperative 3 months and final follow-up, the modified PKP group was significantly better in all the indexes than the conventional PKP group ( P<0.05). Conclusion:Compared with conventional PKP, the modified PKP may lead to better outcomes for Kümmell disease.

Objective:To confirm the possible pathogen causing an outbreak of respiratory infectious disease in Beijing.Methods:Oropharyngeal swabs were collected from 14 cases with fever and detected by RT-PCR for respiratory viruses and bacteria. For specimens positive for adenoviruses, Fiber, Hexon and Penton gene fragments were amplified with specific primers and sequenced. BLAST and phylogenetic tree were used for sequence analysis.Results:All of the 14 specimens were adenovirus-positive. BLAST analysis of the sequences of Fiber, hexon and Penton genes showed that the 14 cases were all caused by adenovirus 3. The phylogenic tree analysis indicated that this adenovirus was closely related to an adenovirus of 3a51 genotype (GenBank No: KF268123) isolated in the USA in 2007.Conclusions:Human adenovirus genotype 3a51 caused this outbreak of respiratory infectious disease in Beijing.
