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.

Objective To analyze the status of radiation protection among non-medical radiation institutions in Henan Province. Methods A total of 673 non-medical radiation institutions in Henan Province were selected as the research subjects using the judgmental sampling method. Their basic information and occupational health management practice were investigated. A total of 131 research subjects were selected for monitoring of occupational exposure to ionizing radiation using the stratified random sampling method. Results Among the 132 institutions using baggage inspection devices, none of the associated radiation workers (1 642 individuals) had received radiation protection training, personal dose monitoring, or occupational medical examination. Besides, among the remaining 541 radiation institutions with 8 373 radiation workers, the rates of radiation protection training, personal dose monitoring, and occupational medical examination were 62.2%, 98.1%, and 80.6%, respectively. The equipping rates for radiation monitoring instruments was 76.7%, for personal dose alarm device was 63.4%, and for the personal protective equipment was approximately 63.2% among the 673 non-medical radiation institutions. And the rate of independent monitoring for occupational radioactive hazard factors in workplaces was 65.2%, the rate of commissioned monitoring was 69.8%, the rate of conducting evaluations on the current status of occupational radioactive hazard was 70.4%, and the declaration rate of occupational hazard factor was 66.7%. The ambient dose equivalent rates for X/γ rays, neutron ambient dose equivalent rates, and average surface contamination levels of α/β particles in 131 radiation institutions met the national requirements. However, in three of the five underground metal mines, radon concentration exceeded 1 000.0 Bq/m³ at some operating detection points, with the highest one reaching 4 223.0 Bq/m³. Conclusion There remains a gap between current radiation protection practice in non-medical radiation workplaces in Henan Province and the requirements of national regulations and standards. Radiation protection management and supervision should be strengthened.

Objective: To compare the effectiveness of blonanserin and olanzapine in the treatment of first-episode schizophrenia, so as to provide the basis for the medication choice for the treatment of first-episode schizophrenia. Methods: A total of 98 patients with first-episode schizophrenia admitted to the Second People's Hospital of Taizhou City were selected and randomly divided into the olanzapine group and the blonanserin group for a treatment period of two months. The Positive and Negative Syndrome Scale (PANSS), Pittsburgh Sleep Quality Index (PSQI), MATRICS Consensus Cognitive Battery (MCCB) were used to investigate the improvement of symptoms, sleep quality and cognitive function before and after treatment, respectively, and the level of prolactin was detected. The generalized estimation equation was used to compare the differences between the two groups. The adverse reactions of the two groups were recorded and the safety of medication was evaluated. Results: Forty-nine patients each group were included, with 29 males and a mean age of (37.22±7.17) years in the olanzapine group, and 27 males and a mean age of (37.54±7.31) years in the blonanserin group. There were no significant differences in gender, age, disease course and educational duration between the two groups (all P>0.05). The scores of positive symptom, negative symptom, general psychopathology and overall PANSS in the two groups after treatment were decreased compared with those before (all P<0.05). However, there was no significant difference between the two groups, and no interaction between the drugs and treatment duration (all P>0.05). The MCCB score of the blonanserin group was higher than that of the olanzapine group, while the PSQI score and the prolactin level of the blonanserin group were lower than that of the olanzapine group, and there was an interaction between the drugs and treatment duration (all P<0.05). The incidence of adverse reactions in the blonanserin group was 6.12%, which was lower than that in the olanzapine group of 20.41% (P<0.05). Conclusion Either blonanserin or olanzapine can improve psychotic symptoms inpatients with first-episode schizophrenia, while blonanserin is more effective than olanzapine in improving sleep quality, cognitive function and reducing prolactin level, and has higher safety.

BACKGROUND:Warm-needling moxibustion can effectively treat knee osteoarthritis.Degeneration,injury and fracture of the anterior cruciate ligament can affect the local stability of the knee joint,and then induce the formation of knee osteoarthritis.Whether warm-needling moxibustion can repair the injured cruciate ligament and the mechanism of action are still unclear. OBJECTIVE:To observe the effects of warm-needling moxibustion on the morphology of the anterior cruciate ligament and the expression of insulin growth factor-1 and transforming growth factor-β in rabbits with knee osteoarthritis and to clarify the mechanism of anterior cruciate ligament repair by warm-needling moxibustion. METHODS:Thirty New Zealand rabbits were randomly divided into blank group,model group and warm-needling moxibustion group,with 10 rabbits in each group.Knee osteoarthritis model was established by plaster cast immobilization.The blank group was not intervened.Rabbits in the model group rabbits were fixed in a rabbit holder for 15 minutes every day.The warm-needling moxibustion group was treated with warm acupuncture,once a day,7 days as a course of treatment,a total of two courses.After treatment,the imaging changes of the anterior cruciate ligament were observed by MRI and MRI grading statistics were performed.Morphological changes of the anterior cruciate ligament were observed by transmission electron microscope and hematoxylin-eosin staining.mRNA and protein expressions of insulin growth factor-1 and transforming growth factor-β were detected by RT-PCR and western blot,respectively. RESULTS AND CONCLUSION:MRI examination:Compared with the blank control group,the anterior cruciate ligament in the model group was thickened,edematous,and partially torn,and the difference in grading statistics was statistically significant(P＜0.05).Compared with the model group,the anterior cruciate ligament in the warm-needling moxibustion group was slightly thickened,with mild edema and no tearing,and the difference in grading statistics was statistically significant(P＜0.05).General observation:In the model group,the surface of the anterior cruciate ligament was glossy and faded,with the edge being covered with flocculent periosteum and obvious tissue necrosis;in the warm-needling moxibustion group,the surface of the ligament was glossy,and the ligament was in a normal helical shape.Hematoxylin-eosin staining:In the model group,there was obvious tissue necrosis in the anterior cruciate ligament,a large number of new capillaries,loosely arranged fibroblasts and collagen fibers.In the warm-needling moxibustion group,there was a small amount of tissue necrosis and few new vessels in the anterior cruciate ligament,and the cells and collagen fibers were loosely and irregularly arranged.Transmission electron microscopy:In the model group,the fibers in the anterior cruciate ligament were arranged in a disordered way with uneven thickness and distribution,and there are more fibroblasts that were irregular in morphology;in the warm acupuncture group,the fibers were basically arranged longitudinally,with uneven thickness and distribution,and a small number of oval-shaped fibroblasts were observed.RT-PCR and western blot assay:mRNA and protein expressions of insulin growth factor-1 and transforming growth factor-β were significantly decreased in the model group compared with the blank control group(P＜0.05),but significant increased after treatment with warm-needling moxibustion(P＜0.05).To conclude,warm-needling moxibustion can alleviate anterior cruciate ligament injury and regulate the expression of insulin growth factor-1 and transforming growth factor-β to treat knee osteoarthritis.

BACKGROUND:Traditional scoliosis orthosis has some disadvantages,such as complex manufacturing process,long processing cycle,poor fit and so on.Three-dimensional printed scoliosis orthosis has the advantages of high manufacturing precision and personalization. OBJECTIVE:To evaluate the efficacy of three-dimensional printed scoliosis orthosis for scoliosis based on multi-criteria decision model. METHODS:Clinical data of 72 patients with scoliosis admitted to Chen Xinghai Hospital of Integrated Traditional Chinese and Western Medicine from January 2019 to October 2022 were retrospectively collected and divided into two groups according to the treatment of orthosis.Study group(n=23)received three-dimensional printed scoliosis orthosis.Traditional group(n=49)received the traditional polypropylene spine brace treatment.The clinical efficacy and complications were compared between the two groups.A multi-criteria decision model for the treatment of scoliosis with three-dimensional printed scoliosis orthosis was established,and the stability of the benefit value,risk value and decision model of the two groups were evaluated. RESULTS AND CONCLUSION:(1)Compared with the traditional group,there were significant differences in the top vertebral offset distance,Cobb angle,top vertebral rotation,Functional Movement Screen score,visual analog scale score and total effective rate in the study group at 6 months after surgery(P<0.05).(2)Among the benefit indexes,Cobb angle had the greatest impact on the condition of patients,while the risk indexes had the greatest impact on dyspnea.(3)The benefit values of the study group and the traditional group for scoliosis were 79 and 64,and the risk values were 74 and 57,respectively.The combined benefit and risk values found that the benefit-risk value of the study group was 16 higher than that of the traditional group.(4)In the range of 0-100%relative risk weight,the benefit-risk value of the study group was always higher than that of the traditional group,which proved that the multi-criteria decision-making model had good stability.(5)It is indicated that three-dimensional printed scoliosis orthosis can better restore the physiological curvature of scoliosis and improve the efficiency of treatment.

As essential concepts of the traditional Chinese medicine theory,"deficiency"and"toxin"have been enriched and developed continuously since Huangdi Neijing.By tracing back and combing"deficiency"and"toxin",this paper sums up their relationship,analyzes and explains their basic connotation,and discusses their extension.The"deficiency-toxin"theory has two meanings:it covers the pathological state of the human body with deficiency of vital qi and excess of pathogenic toxin,and it also refers to the pathological evolutionary process in which"deficiency"and"toxin"promote each other.Based on the connotation and dynamic pathogenesis of the"deficiency-toxin"theory,it is pointed out that this theory can be applied to the prevention and treatment of infectious diseases and chronic debilitating diseases,including the"inflammation-cancer transformation"of inflammatory bowel disease.Taking inflammatory bowel disease as an example and combining its Western medical background,this paper expounds on the pathogenesis and treatment of the"inflammation-cancer transformation"of inflammatory bowel disease,and provides a paradigm of"deficiency-toxin"theory guiding clinical research.

Objective To evaluate the efficacy of Huachansu tablets combined with transarterial chemoembolization(TACE)for treatment of primary hepatocellular carcinoma(HCC)and prognostic influence factors.Methods One hundred and eight patients with HCC were recruited according to the inclusion and exclusion criteria.Patients were randomly divided into treatment group and control group.The treatment group was treated with Huachansu tablets combined with TACE,and the control group was treated with TACE alone,with overall survival time(OS)and progression-free survival time(PFS)as the evaluation indexes.The COX regression analysis was used to evaluate the survival and prognostic effects and their influence factors in both groups.Results A total of 108 HCC patients were enrolled.The OS was 13.5 months in treatment group and 9.2 months in control group;the PFS was 6.8 months in treatment group and 5.3 months in control group,and the differences were significant statistically(all P<0.05).Multivariate COX regression analysis showed that Child-Pugh grade and cirrhosis were the independent risk factors for PFS in HCC patients.Child-Pugh grade were the independent risk factors for OS in HCC patients.ALBI is a protective factor for OS in HCC patients.Conclusions The treatment of HCC by Huachansu tablets combined with TACE can delay the progression of HCC and prolong PFS and OS of the patients with HCC.Child-Pugh grade,cirrhosis status,and ALBI were important factors affecting the prognosis of the patients with HCC.

Objective:To analyze the risk factors and prognosis for early acute kidney injury (AKI) after orthotopic liver transplantation (OLT).Methods:The retrospective study was conduc-ted. The clinicopathological data of 340 pairs of donor and recipients undergoing OLT in The First Affiliated Hospital of Nanjing Medical University from January 2016 to January 2020 were collected. There were 262 males and 78 females of donors. There were 268 males and 72 females of recipients, aged (51±11)years. Of 340 recipients, 217 cases without postoperative early AKI were divided into the non-AKI group and 123 cases with postoperative early AKI were divided into the AKI group. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distri-bution were represented as M( IQR), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the non-parameter test. Multivariate analysis was conducted using the binary Logistic regre-ssion model with forward method. The nomogram predictive model was constructed using the R software with its RMS package (R3.6.1). The efficacy of the predictive model was validated using the area under curve (AUC) of the receiver operating characteristic (ROC) curve, and internal validation of the predictive model was performed using the Bootstrap method. The Kaplan-Meier method was used to draw survival curves, and Log-rank test was used for survival analysis. Results:(1) Com-parison of preoperative clinical characteristics between donors and recipients of the non-AKI group and the AKI group. There was a significant difference in overweight of donors between the non-AKI group and the AKI group ( P<0.05). There were significant differences in preoperative hypertension, viral hepatitis, pathological types, international normalized ratio, fibrinogen levels, platelet (PLT), hemoglobin, and anemia of recipients between the non-AKI group and the AKI group ( P<0.05). (2) Comparison of surgical situations between recipients of the non-AKI group and the AKI group. There were significant differences in intraoperative urine output, volume of intraoperative blood loss, peak serum potassium after reperfusion, massive transfusion, plasma infusion, cryoprecipitate infusion, and aminocaproic acid use of recipients between the non-AKI group and the AKI group ( P<0.05). (3) Influencing factors for postoperative early AKI and construction and evaluation of the nomogram predictive model for postoperative early AKI. Results of multivariate analysis showed that donors of overweight, recipients of preoperative hypertension, recipients of non-viral hepatitis, recipients of preoperative severe PLT reduction, recipients of less intraoperative urine output, recipients of severe post-reperfusion hypotension, recipients of high peak serum potassium after reperfusion, recipients with intraoperative plasma infusion were independent risk factors for postoperative early AKI ( odds ratio=1.982, 3.365, 0.519, 3.615, 0.169, 2.480, 1.500, 1.001, 95% confidence interval as 1.160-3.388, 1.649-6.865, 0.293-0.917, 1.358-9.621, 0.061-0.464, 1.246-4.934, 1.003-2.243, 1.000-1.001, P<0.05). The nomogram predictive model for postoperative early AKI was constructed based on the results of multivariate analysis. Results of ROC curve showed the AUC was 0.769 (95% confidence interval as 0.717-0.820). Results of the calibration curve showed that the predictive results of nomogram predictive model fitted well with the actual situation, with a mean absolute error of 0.016. (4) Comparison of prognosis between recipients of the non-AKI group and the AKI group. There were significant differences in postopera-tive peak creatinine, peak brain natriuretic peptide, duration of intensive care unit stay, mechanical ventilation time, re-intubation of recipients between the non-AKI group and the AKI group ( Z=-4.836, -5.652, -5.861, -6.533, χ2=14.676, P<0.05). All 340 recipients were followed up. For recipients of hepatocellular carcinoma, the 6-month survival rates after surgery were 87.8% and 75.6% of the non-AKI group and the AKI group, respectively, showing a significant difference between them ( χ2=4.010, P<0.05), and the overall survival rates were 46.7% and 56.1% of the non-AKI group and the AKI group, respectively, showing no significant difference between them ( χ2=0.047, P>0.05). For recipients of benign liver disease, the 6-month survival rates after surgery were 89.8% and 78.0% of the non-AKI group and the AKI group, respectively, showing a significant difference between them ( χ2=6.401, P<0.05), and the overall survival rates were 81.4% and 68.0% of the non-AKI group and the AKI group, respectively, showing a significant difference between them ( χ2=4.452, P<0.05). Conclusions:Donors of overweight, recipients of preoperative hypertension, recipients of non-viral hepatitis, recipients of preoperative severe PLT reduction, reci-pients of less intraoperative urine output, recipients of severe post-reperfusion hypotension, recipi-ents of high peak serum potassium after reperfusion, recipients with intraoperative plasma transfu-sion were independent risk factors for postoperative early AKI. Nomogram predictive model has well clinical application value. For recipients of benign liver disease, the 6-month survival rate after surgery and overall survival rate of recipients in the non-AKI group are superior to those of the AKI group.

OBJECTIVE To explore the application value of indocyanine green combined with near-infrared autofluorescence imaging technique in identifying pathological parathyroid glands during surgery for primary hyperparathyroidism (PHPT). METHODS Data from 40 patients with PHPT treated in Beijing Tongren Hospital,Capital Medical University were collected,including 10 patients in the indocyanine green treated group and 30 patients in the non-treated group. All patients underwent surgical treatment to remove the affected parathyroid glands. Near-infrared autofluorescence imaging was used for image acquisition,and ImageJ software was used for fluorescence intensity analysis. RESULTS The fluorescence intensity of the pathological parathyroid glands in the indocyanine green-treated group was significantly higher than that in the non-treated group(142.7±23.7 vs. 94.5±31.4,t=-4.434,P=0.000);the fluorescence ratio of pathological parathyroid glands/thyroid glands was significantly higher than that in the non-treated group(1.6±0.3 vs. 1.2±0.4,t=-3.162,P=0.004). There was no correlation between the fluorescence intensity of parathyroid glands in the non-treated group and preoperative blood calcium(r=0.029,P=0.088) and preoperative PTH level(r=-0.142,P=0.455),and there was also no correlation between the fluorescence intensity of parathyroid glands in the treated group and preoperative blood calcium(r=0.206,P=0.568) and preoperative PTH level(r=0.160,P=0.658). The detection rate of near-infrared light in the non-treated group was 53.3％(16/30),while that in the treated group was 100％(10/10). The average detection time for the non-treated group was (71.0±16.9)minutes,while that for the treated group was (52.7±11.1)minutes,with a significant difference between the two groups(t=3.187,P=0.003). CONCLUSION The combination of indocyanine green and near-infrared autofluorescence imaging technique is helpful for identifying the diseased parathyroid glands during the surgical treatment of PHPT.
