Objective:To compare the antiosteoporosis effect of conventional treatment and conventional treatment combined with Denosumab after percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fractures (OVCF).Methods:A retrospective cohort study was conducted to analyze the clinical data of 211 patients with OVCF admitted to the Second Affiliated Hospital of Soochow University from September 2020 to September 2022. All the patients were female, aged 56-90 years [(71.4±8.1)years]. The bone mineral density T-score of the lumbar spine was (-2.6±1.0)SD before operation. Fracture segments included T 1-T 9 in 45 patients, T 10-L 2 in 146, and L 3-L 5 in 69. Of all, 174 patients were treated with single-segment surgery, 25 with two-segment surgery and 12 with surgery involving three or more segments. According to the wishes of the patients, 107 patients were treated with daily oral administration of calcium and active Vitamin D after PKP (conventional treatment group) and 104 patients with Denosumab combined with the conventional treatment after PKP (Denosumab therapy group). The bone mineral density T-scores of the lumbar spine of the two groups were compared before surgery and at the last follow-up. The visual analogue scale (VAS) and Oswestry disability index (ODI) before surgery, at 3 days, 6 months after surgery, and at the last follow-up were evaluated and the refracture rate after surgery was detected. Possible adverse effects after medication during anti-osteoporosis treatment were observed in two the groups. Results:All the patients were followed up for 12-24 months [(13.5±2.0)months]. Before surgery, the bone mineral density T-score of the lumbar spine was (-2.7±1.1)SD in the Denosumab therapy group and (-2.5±0.8)SD in the conventional treatment group ( P>0.05). At the last follow-up, the bone mineral density T-score of the lumbar spine was (-2.1±1.1)SD in the Denosumab therapy group, significantly higher than (-2.5±0.9)SD in the conventional treatment group ( P<0.05). In the Denosumab therapy group, the bone mineral density T-score of the lumbar spine at the last follow-up was significantly increased compared to that before surgery ( P<0.01), while there was no significant difference in the conventional treatment group ( P<0.05). Before surgery and at 3 days after surgery, the VAS scores and ODI values were (8.5±0.9)points, (2.8±0.8)points, 48.7±4.8 and 25.6±4.0 in the Denosumab therapy group, which was not statistically different from those in the conventional treatment group [(8.5±1.3)points and (2.8±0.9)points, 47.9±7.0 and 25.9±3.7] ( P>0.05). At 6 months after surgery and at the last follow-up, the VAS scores and ODI values were (2.2±0.8)points, (1.7±0.8)points, 24.2±3.6 and 23.2±4.1 in the Denosumab therapy group, significantly lower than those of the conventional treatment group [(2.8±0.9)points, (2.8±1.1)points, 26.4±3.2 and 27.3±4.0] ( P<0.01). The VAS scores at each time point after surgery in both groups decreased significantly compared with those before surgery ( P<0.05). The VAS scores continued to decrease after surgery in the Denosumab therapy group ( P<0.05), while no significant difference was found among those at different time points in the conventional treatment group ( P>0.05). The ODI values at each time point after surgery in both groups significantly decreased compared to those before surgery ( P<0.05). The ODI values continued to decrease after surgery in the Denosumab therapy group ( P<0.05), while in the conventional treatment group, no significant difference was found between those at 6 months after surgery and those at 3 days after surgery ( P>0.05) and they were improved at the last follow-up compared with those at 3 days after surgery ( P<0.05). The refracture rate after surgery was 6.7% (7/104) in the Denosumab therapy group, significantly lower than 16.8% (18/107) in the conventional treatment group ( P<0.05). No serious complications were observed during the antiosteoporosis period in either group. Conclusion:Compared with daily oral administration of Calcium and active Vitamin D after PKP, the conventional treatment combined with Denosumab after PKP can effectively increase the bone density, relieve pain continuously, improve functional restoration, and reduce the risk of refracture in OVCF patients.

Using digital technologies in concurrently performing missing tooth implantation and preparation of remaining teeth is a solution to reduce the number of visits and improve efficiency. This paper proposes a digital process for simultaneously implanting and preparing teeth. It integrates implant surgical guide and 3D-printed tooth preparation guide into a single guide and completes guided implant placement and precise tooth preparation. Based on "repair-oriented" virtual implant planning, the implant surgical guide can improve the efficiency and predictability of implant placement, and its linear accuracy is about 1 mm. The tooth preparation guide precisely guides tooth preparation and restoration space visualization, ensuring the quality of the tooth preparation. The two guides have different design accuracy requirements, and thus their combination improves the overall guiding accuracy requirements. The concurrent application of the two guides minimizes the clinical operation time, number of visits, and economic burden of patients.

Objective:To explore the risk factors of perioperative outcomes of lung transplantation and establish a predictive model for delayed extubation after lung transplantation.Methods:From January 1, 2020 to December 31, 2022, 104 lung transplantation recipients were retrospectively collected to identify the risk factors of early post-operative outcome.According to the timing of extubation post-lung transplantation, they were assigned into two groups of normal(77 cases)and delayed(27 cases). Baseline profiles, type of primary diagnosis, cold ischemic duration and lung transplantation approach were compared between two groups.The factors with significant difference were examined by univariate and multivariate Logistic regression.Furthermore, multivariate logistic model was visualized by a nomogram.Receiver operating characteristic(ROC)curve and decision curve analysis(DCA) were performed for evaluating the model's predictive performance and its value for clinical utilization.Results:The postoperative mortality rate was 9.6%.Delayed extubation was a strong predictor for postoperative mortality.Cold ischemic time outperformed others variates in terms of delayed extubation prediction.AUC of cold ischemic time and multivariate logistic model was 0.75(95% CI: 0.69-0.81)and 0.87(95% CI: 0.82-0.91). Conclusions:Delayed postoperative extubation is a key predictor of early post-lung transplantation mortality.The established predictive model may effectively identify high-risk patients for preventive intervention and survival improvement post-lung transplantation.

Discipline evaluation is an important measure to promote the virtuous circle of discipline construction, and is an indispensable link in the process of discipline development in public hospitals. After becoming a directly affiliated hospital of a " double first-class" university, in order to improve the comprehensive strength and influence, a hospital built and applied a disciplinary evaluation system in four directions: talent construction, clinical medicine, scientific research ability, and teaching work. According to the evaluation results, the hospital′s disciplines were divided into three categories, namely, advantageous disciplines, cultivating disciplines and potential disciplines, and development strategies were established at different levels, providing policy support and financial support, especially in the field of scientific research and teaching, to accelerate to make up for shortcomings. Through exploration and practice, the talent team, scientific research and teaching level, discipline reputation, and comprehensive strength of the hospital had been significantly improved, providing effective support for the high-quality development of the hospital.

β-thalassemia is a single-gene genetic disease caused by β globin gene mutations leading to the fact that red blood cells are unable to form normal adult hemoglobin, and then patients develop hemolytic anemia. Current treatment regimens mainly include allogenetic hematologic stem cell transplantation, symptomatic regular blood transfusions and the use of iron removers to reduce iron load. Some severe patients have quite poor prognoses and deadly consequences if not treated timely. Genetically modified autohematopoietic stem cells can provide a new treatment option for patients with β thalassemia, which may achieve a long-term and stable increase in hemoglobin level through a single dose, making one-time cure β-thalassemia possible. This paper reviews the key elements of clinical trial design for β-thalassemia gene therapy from the aspects of efficacy evaluation endpoints, clinical trial design, enrollment population, and subject monitoring in order to provide a reference for pharma-therapeutic research and development enterprises.

Objective:To explore the clinical pathological characteristics and initial 131I curative responses of familial differentiated thyroid cancer (FDTC) and sporadic differentiated thyroid cancer (SDTC). Methods:A total of 66 FDTC patients (19 males, 47 females, age (39.8±11.7) years) and 1 701 SDTC patients (442 males, 1 259 females, age (40.9±11.3) years) who underwent 131I therapy in Department of Nuclear Medicine, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology between January 2010 and August 2018 were retrospectively enrolled. The clinical pathological characteristics, preablative stimulated thyroglobulin (ps-Tg), preablative stimulated thyroglobulin antibody (ps-TgAb) and response to initial therapy (excellent response, indeterminate response, biochemical incomplete response, structural incomplete response) of two groups were analyzed and compared. The clinical pathological parameters included age, gender, pathological type, tumour maximum diameter, bilateral, multifoci, nodules goiter, thyroiditis, thyroid membrane invasion, lymph node metastasis (LNM), invasion of the surrounding soft tissues, distant metastasis, TNM staging and American Thyroid Association (ATA) risk stratification (low-risk, intermediate-risk, high-risk). χ2 test or Fisher exact test and independent-sample t test were used to compare the data between two groups. Results:Comparing with SDTC group, FDTC group showed higher proportion of bilateral foci (45.5%(30/66) vs 31.2%(530/1 701); χ2=5.999, P=0.010), thyroid membrane invasion (43.9%(29/66) vs 26.6%(452/1 701); χ2=9.672, P=0.002) and distant metastasis (15.2%(10/66) vs 6.2%(105/1 701); χ2=8.418, P=0.004). There was a statistical difference in risk stratification between two groups (high-risk: 18.2%(12/66) vs 9.2%(156/1 701); intermediate-risk: 68.2%(45/66) vs 72.7%(1 237/1 701); low-risk: 13.6%(9/66) vs 18.1%(308/1 701); χ2=6.898, P=0.030). But the tumor maximum diameter of FDTC group was smaller than that of SDTC group ((1.24±0.74) vs (1.50±0.92) cm; t=-2.275, P=0.020). There were no significant differences in other clinical pathological parameters between FDTC group and SDTC group ( t=-0.804, χ2 values: 0.101-5.359, all P>0.05). There were no significant differences between two groups in the postoperation ps-Tg, ps-TgAb levels and the response to initial therapy after 131I treatment ( χ2 values: 0.059-1.915, all P>0.05). Conclusions:The FDTC group displays distinct characteristics as increased aggressiveness at diagnosis. But after accurately treatment, there is no significant difference in the response to therapy between two groups.

Objective:To systematically evaluate the effect of hydrocortisone combined with vitamin C and vitamin B1 on the efficacy of patients with sepsis or septic shock.Methods:Databases including CNKI, Sino Med, VIP, Wanfang, PubMed, the Cochrane Library, and Embase were searched from inception to January 2021 for the randomized controlled trial (RCT) about hydrocortisone combined with vitamin C and vitamin B1 to treat sepsis or septic shock. The experimental group was given intravenous injection of hydrocortisone, vitamin B1 and vitamin C based on conventional treatment; the control group was given conventional treatment or placebo/hydrocortisone/hydrocortisone+vitamin B1 based on conventional treatment. Outcome indicators included sequential organ failure assessment (SOFA), mortality, the duration of vasoactive drugs, new acute kidney injury (AKI) patients, length of stay in intensive care unit (ICU) and in hospital. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias in the included studies. RevMan 5.3 software was then used to perform Meta-analysis. Funnel plot was used to test publication bias.Results:A total of 6 articles involving 816 patients were included, with 411 patients in the experimental group and 405 patients in the control group. The Meta-analysis results showed that the duration of vasoactive drugs in the experimental group was significantly shorter than that in the control group [mean difference ( MD) = -24.02, 95% confidence interval (95% CI) was -32.36 to -15.68, P < 0.000 01]. However, there were no significant differences in SOFA, mortality, new AKI patients, the length of ICU stay and hospital stay between the two groups [SOFA: MD = -0.14, 95% CI was -1.15 to 0.87, P = 0.79; mortality: relative risk ( RR) = 0.99, 95% CI was 0.81 to 1.21, P = 0.92; new AKI patients: RR = 1.10, 95% CI was 0.42 to 2.87, P = 0.84; length of ICU stay: MD = 1.33, 95% CI was -2.22 to 4.89, P = 0.46; length of hospital stay: MD = 1.02, 95% CI was -0.66 to 2.69, P = 0.23]. The funnel plot showed that most of the points were symmetrical and showed an inverted funnel shape, suggesting that the publication bias among the studies was small. There was no significant publication bias on this Meta-analysis. Conclusions:Hydrocortisone combined with vitamin C and vitamin B1 can shorten the duration of vasoactive drugs in patients with sepsis or septic shock, but it cannot effectively reduce the SOFA score, mortality, new AKI patients, length of stay in ICU and in hospital. Limited by the number and quality of the included studies, further large-scale, multi-center, blinded, RCT are still needed for verification.
