BACKGROUND:Allogeneic hematopoietic stem cell transplantation is an important treatment for malignant hematological diseases,and delayed postoperative platelet implantation is a common complication that seriously affects the quality of patient survival;however,there are no standard protocols to improve platelet implantation rates and prevent platelet implantation delays. OBJECTIVE:To compare the safety and efficacy of oral Herombopag Olamine versus subcutaneous recombinant human thrombopoietin for promoting platelet implantation in patients with malignant hematological diseases undergoing haploid hematopoietic stem cell transplantation. METHODS:Clinical data of 163 patients with malignant hematological diseases who underwent haploidentical hematopoietic stem cell transplantation from January 2016 to October 2022 were retrospectively analyzed.A total of 72 patients who started to subcutaneously inject recombinant human thrombopoietin at+2 days were categorized into the recombinant human thrombopoietin group;a total of 27 patients who started to orally take Herombopag Olamine at+2 days were categorized into the Herombopag Olamine group;and 64 patients who did not apply Herombopag Olamine or recombinant human thrombopoietin were categorized into the blank control group.The implantation status,incidence of acute graft-versus-host disease of degree II-IV within 100 days,1-year survival rate,1-year recurrence rate,and safety were analyzed in the three groups. RESULTS AND CONCLUSION:(1)The average follow-up time was 52(12-87)months.The implantation time of neutrophils in the blank control group,recombinant human thrombopoietin group,and Herombopag Olamine group was(12.95±3.88)days,(14.04±3.71)days,and(13.89±2.74)days,respectively,with no statistically significant difference(P=0.352);the implantation time of platelets was(15.16±6.27)days,(17.67±6.52)days,and(17.00±4.75)days,with no statistically significant difference(P=0.287).(2)The complete platelet implantation rate on day 60 was 64.06%,90.28%,and 92.59%,respectively,and the difference was statistically significant(P<0.001).The subgroup analysis showed that the difference between the blank control group and the recombinant human thrombopoietin group was statistically significant(P<0.001),and the difference between the blank control group and the Herombopag Olamine group was statistically significant(P=0.004).The difference was not statistically significant between the recombinant human thrombopoietin group and Herombopag Olamine group(P=0.535).(3)100-day II-IV degree acute graft-versus-host disease incidence in the blank control group,recombinant human thrombopoietin group,and Herombopag Olamine group were 25.00%,30.56%,and 25.93%,respectively,and the difference was not statistically significant(P=0.752).(4)The incidence of cytomegalovirus anemia,cytomegalovirus pneumonia,and hepatic function injury had no statistical difference among the three groups(P>0.05).(5)During the follow-up period,there was no thrombotic event in any of the three groups of patients.(6)The results showed that recombinant human thrombopoietin and Herombopag Olamine could improve the platelet implantation rate of malignant hematological disease patients after haploidentical hematopoietic stem cell transplantation,with comparable efficacy and good safety.

Hypertension is the primary but controllable risk factor leading to increased morbidity and mortality of cardiovascular diseases worldwide.It is very important to control hypertension to reduce the occurrence of serious complications of heart,brain,kidney and fundus.In recent years,there has been a continuous increase in the number of hypertensive patients worldwide,among which there are a large number of elderly hypertensive patients.Compared with urban elderly hypertensive patients,rural elderly hypertensive patients are a more special group.They have the characteristics of less developed economy,lower education level,inconvenient transportation conditions,and inconvenient purchase of drugs and medical treatment.This leads to poor medication compliance and poor blood pressure control.This paper reviews the concept and assessment tools of medication compliance,domestic and foreign research status of medication compliance in rural elderly patients with hypertension,and its influencing factors,in order to better understand the reasons for poor medication compliance,so as to further improve medication compliance and better control blood pressure.

Background: Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) on the surface of Streptococcus dysgalactiae, coded with gapC, is a glycolytic enzyme that was reported to be a moonlighting protein and virulence factor. Objective: This study assessed GAPDH as a potential immunization candidate protein to prevent streptococcus infections. Methods: Mice were vaccinated subcutaneously with recombinant GAPDH and challenged with S. dysgalactiae in vivo. They were then evaluated using histological methods. rGAPDH of mouse bone marrow-derived dendritic cells (BMDCs) was evaluated using immunoblotting, reverse transcription quantitative polymerase chain reaction, and enzyme-linked immunosorbent assay methods. Results: Vaccination with rGAPDH improved the survival rates and decreased the bacterial burdens in the mammary glands compared to the control group. The mechanism by which rGAPDH vaccination protects against S. dysgalactiae was investigated. In vitro experiments showed that rGAPDH boosted the generation of interleukin-10 and tumor necrosis factor-α. Treatment of BMDCs with TAK-242, a toll-like receptor 4 inhibitor, or C29, a toll-like receptor 2 inhibitor, reduced cytokines substantially, suggesting that rGAPDH may be a potential ligand for both TLR2 and TLR4. Subsequent investigations showed that rGAPDH may activate the phosphorylation of MAPKs and nuclear factor-κB. Conclusions GAPDH is a promising immunization candidate protein for targeting virulence and enhancing immune-mediated protection. Further investigations are warranted to understand the mechanisms underlying the activation of BMDCs by rGAPDH in a TLR2- and TLR4-dependent manner and the regulation of inflammatory cytokines contributing to mastitis pathogenesis.

BackgroundInternet-based cognitive behavioral therapy （ICBT） is progressively emerging as an efficacious alternative to alleviate anxiety and depression in cancer patients. To date， no Meta-analysis has been conducted specific to the effect of ICBT on anxiety， depression， distress and quality of life in cancer patients. ObjectiveTo assess the effect of ICBT on distress， depression， anxiety and quality of life in cancer patients through a systematic review of the literature. MethodsOn March 28， 2022， PubMed， PsycINFO， Embase， Cochrane Library， Web of Science， CNKI， VIP， Wanfang Data and CBM were retrieved for the randomized controlled trials （RCTs） involving ICBT targeting either distress， depression， anxiety， quality of life or all in cancer patients. After the risk of bias assessment， Stata 17.0 software was used for Meta-analysis. ResultsA total of 12 RCTs with a total sample size of 1 686 patients were included. Meta-analysis revealed that the superiority of ICBT over controls was evident for interventions targeting distress in cancer patients （SMD=-0.547， 95% CI： -1.090~-0.145， P<0.01）， while appeared to be less evident for the interventions targeting depression （SMD=-0.652， 95% CI： -1.734~0.002， P=0.051）， anxiety （SMD=-1.045， 95% CI： -3.656~0.101， P=0.088） and quality of life （SMD=0.234， 95% CI： -0.064~0.449， P=0.112） in cancer patients，and dropout rate was higher in ICBT group than that in control group （OR=1.795， 95% CI：1.358~2.374， P<0.01）. ConclusionICBT is reported to be effective in alleviating distress in cancer patients， whereas results inconsiderable improvements over depression， anxiety and quality of life in cancer patients.

Objective:To explore one-stage total knee arthroplasty (TKA) combined with open reduction and internal fixation (ORIF) for knee osteoarthritis complicated with tibial stress fracture.Methods:The 3 patients were retrospectively analyzed who had been treated for knee osteoarthritis complicated with tibial stress fracture at Department of Orthopedics, Ganzhou District People＇s Hospital from March 2018 to March 2020. They were all female, aged from 54 to 76 years (average, 66 years). There were 2 transverse fractures and one short oblique fracture; all of them had knee varus deformity. The Hospital for Special Surgery (HSS) scores averaged 37.6 (from 28 to 50) for the left knee and 28.3 (from 22 to 39) for the right knee. One-stage TKA was performed for the articular surface while ORIF for the right tibial stress fracture for all patients. Recorded were fracture union time, HSS knee score and range of articular motion.Results:The 3 patients were followed up for 25 to 44 months (average, 32 months).The fracture union time ranged from 4 to 7 months (average, 5 months). The last follow-ups revealed no such complications as prosthesis loosening, peri-prosthesis osteolysis or joint instability. Knee varus deformity was corrected in all patients. The HSS knee scores at the last follow-up averaged 89.6 (from 88 to 91) for the left knee and 88.3 (from 85 to 90) for the right knee.Conclusion:In the treatment of knee osteoarthritis complicated with tibial stress fracture, one-stage TKA combined with ORIF can restore the function of knee joint, leading to fine curative effects.

Meanwhile, combining the two-factor theory and practical experience, the problems that existed in the innovation incentive policy of public hospitals for young medical talents were analyzed, and the corresponding countermeasures were proposed to build the innovation incentive path of young medical talents under the two-factor theory.Results:Based on analyzing the demand characteristics of young medical talents, managers should distinguish health care factors and incentive factors, and implement incentives from both aspects. Provide incentives through improving the personal sense of achievement, creating a personal growth environment, and promoting professional titles to stimulate young talents' innovation motivation; implement health care factors from aspects of working conditions, material benefits, salary levels, etc.Conclusions:As a new concept of development, high-quality development is not only reflected in scientific and technological innovation-driven, but also in the innovation of management mechanisms so that institutional innovation becomes the driving force for high-quality development.

Objective To establish a nomogram for predicting the risk of post-hepatectomy complications (PHC) in hepatic echinococcosis by analyzing the risk factors for PHC in two types of hepatic echinococcosis, and to investigate its value in clinical practice. Methods A retrospective analysis was performed for the clinical data of 263 patients with two types of hepatic echinococcosis who underwent hepatectomy in Qinghai University Affiliated Hospital from January 2015 to August 2020, and among these patients, 93 were enrolled as PHC group and 170 were enrolled as control group. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the independent samples t -test was used for comparison of normally distributed continuous data between two groups; the chi-square test and the Fisher's exact test were used for comparison of categorical data between two groups. Univariate and multivariate logistic regression analyses were used to screen out independent risk factors for PHC, and a nomogram risk prediction model was established based on the weight of each independent risk factor. The Bootstrap resampling method was used for internal verification of the model; the receiver operating characteristic (ROC) curve was plotted to evaluate the discriminatory ability of the model; calibration curve and the Hosmer-Lemeshow test were used to evaluate the consistency of the model; decision curve analysis (DCA) was performed to verify the clinical effectiveness of the model. Results Albumin-bilirubin (ALBI) score (odds ratio [ OR ]=3.694, 95% confidence interval [ CI ]: 1.860-7.336, P < 0.05), time of operation ( OR =2.848, 95%CI: 1.384-5.859, P < 0.05), intraoperative blood loss ( OR =4.832, 95%CI: 2.384-9.793, P < 0.05), and hydatid diameter ( OR =3.073, 95%CI: 1.528-6.177, P < 0.05) were independent risk factors for PHC in two types of hepatic echinococcosis. A nomogram risk prediction model was established based on the weight of the above four independent risk factors, and the model had an area under the ROC curve of 0.877 (95% CI : 0.831-0.923). The model had a consistency index of 0.871 after internal verification using the Bootstrap resampling method, suggesting that the model had good discriminatory ability. The fitting of the observed value and the actual value of the calibration curve and the Hosmer-Lemeshow test ( P =0.905) showed that the predicted value of the nomogram risk prediction model had good consistency with the actual observed value. When the threshold probability was 35.6%, DCA showed a net clinical benefit of 22%, and the model had good clinical applicability within the threshold probability ranging from 8% to 89%. Conclusion ALBI score, time of operation, intraoperative blood loss, and hydatid diameter are independent risk factors for PHC in patients with two types of hepatic echinococcosis, and the nomogram risk prediction model established based on these factors has good accuracy, consistency, and clinical practicability.

Objective:To investigate the clinical characteristics and influencing factors of mortality in patients with intra-abdominal candidiasis (IAC).Methods:The retrospective case-control study was conducted. The clinicopathological data of 203 IAC patients who were admitted to 7 medical centers from June 2018 to June 2020 were collected, including 54 cases in Sir Run Run Shaw Hospital of Zhejiang University School of Medicine, 31 cases in Fujian Medical University Union Hospital, 25 cases in Beijing Hospital, 25 cases in the First Affiliated Hospital of Xi'an Jiaotong University, 24 cases in China-Japan Friendship Hospital, 22 cases in General Hospital of Eastern Theater Command of Chinese PLA and 22 cases in Chongqing University Cancer Hospital. There were 130 males and 73 females, aged (64±15)years. Observation indicators: (1) candida infection and treatment of IAC patients; (2) analysis of influencing factors for mortality of IAC patients. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate and multivariate analyses were performed by Logistic regression model. Results:(1) Candida infection and treatment of IAC patients: 134 cases of candida albicans were cultured in the initial abdominal drainage fluid or intraoperative abdominal specimens of 203 patients, and 49 cases were treated with fluconazole. Of 69 cases infected with non candida albicans, 13 cases were treated with fluconazole. The resistance rate of candida albicans to fluconazole was 5.91%(12/203). Of 203 patients, there were 68 cases with infections shock, 53 cases with renal failure, 84 cases with respiratory failure and 63 cases with multiple organ failure, respectively. There were 148 of 203 patients admitted to intensive care unit for 9 days(range, 3-20 days), and the total hospital stay was 28 days(range, 17-50 days). Of 203 patients, 86 cases were cured and discharged, 50 cases were improved and transferred to local hospitals, 32 cases gave up treatment and discharged automatically, 19 cases died, 16 cases had no follow-up data. The mortality was 25.12%(51/203). (2) Analysis of influencing factors for mortality of IAC patients. Results of univariate analysis showed that acute physiology and chronic health evaluation score, sequential organ failure assessment score, the Cr, bilirubin, albumin, procalcitonin, and PLT on the first day of candida positive culture, of the lowest value in a week and the highest in a week, heart disease, diabetes, infections shock, renal failure, respiratory failure, multiple organ failure, anti-fungal therapy were the related factors for mortality of IAC patients ( t=-2.322, Z=-2.550, -2.262, -4.361, t=2.085, Z=-3.734, -5.226, -2.394, -5.542, t=3.462, Z=-4.957, -5.632, 3.670, -5.805, t=3.966, Z=-3.734, -5.727, χ2=4.071, 4.638, 27.353, 18.818, 13.199, 26.251, 13.388, P<0.05). Multivariate analysis showed that the bilirubin, procalcitonin on the first day of candida positive culture and infections shock were independent risk factors for mortality of IAC patients ( odds ratio=1.021, 1.022, 6.864, 95% confidence interval as 1.010-1.033, 1.001-1.044, 1.858-25.353, P<0.05). Conclusions:The common fungus of IAC was candida albicans, and fluconazole can be used as the initial empirical treatment. The prognosis of patients with abdominal candidiasis is poor. Bilirubin, procalcitonin on the first day of candida positive culture and infections shock are indepen-dent risk factors for mortality of IAC patients.
