Synergistic effects of Linggui zhugan decoction regulating autophagy on doxorubicin against non-alcoholic fatty liver disease-hepatocellular carcinoma / 中国药房

OBJECTIVE To explore the enhancement effect of Linggui zhugan decoction （LGZG） regulating autophagy on doxorubicin （DOX） against non-alcoholic fatty liver disease-hepatocellular carcinoma （NAFLD-HCC）. METHODS C57BL/6 mice were randomly divided into blank group， NAFLD-HCC group， LGZG group， DOX group and DOX+LGZG group， with 10 mice in each group. The NAFLD-HCC model was established by intraperitoneal injection of diethylnitrosamine （50 mg/kg） and high-fat diet. The blank group was injected with the same amount of normal saline and fed with ordinary diet. After modeling， administration groups were given LGZG aqueous extract （20 g/kg） intragastrically and/or DOX solution intraperitoneally （8 mg/kg）； the blank group and NAFLD-HCC group were given a constant volume of normal saline intragastrically， once a day， for 4 consecutive weeks. The general condition of mice （No.2022-BS-197） was monitored during modeling and drug intervention. After drug intervention， body weight， liver weight and liver coefficient of mice were detected. The histopathologic morphology and fibrosis degree of liver tissue in mice were observed； the levels of blood lipid [the levels of triglyceride （TG）， total cholesterol （TC）， low-density lipoprotein cholesterol （LDL-C） and high-density lipoprotein cholesterol （HDL-C）]， the serum contents of alpha fetoprotein （AFP） and carcinoembryonic antigen （CEA）， and the expressions of marker of proliferation Ki-67， B-cell lymphoma-2 （Bcl-2） and Bcl-2 associated X （Bax） in liver tissue were all detected as well as protein expressions of microtubule-associated proteins 1A and 1B （LC3）， Beclin1 and selective autophagy adopt proteins P62. RESULTS Compared with the blank group， the activity of mice decreased gradually as time in the NAFLD-HCC group； mental fatigue， disheveled and matte hair were observed， and body weight decreased significantly （P＜0.05）； liver weight had an upward trend， and liver coefficient increased significantly （P＜0.05）. The inflammatory cells of liver tissue were infiltrated， with some cells showing ballooning and small cell hyperplasia， and the degree of liver fibrosis was worsened； serum levels of TC， TG and LDL-C， AFP and CEA contents increased significantly， while HDL-C level decreased significantly （P＜0.05）. The protein expressions of Ki-67 and Bcl-2 in liver tissue were increased significantly （P＜0.05）， while the protein expression of Bax decreased. The protein expression of Beclin1 in liver tissue decreased significantly （P＜0.05）； LC3Ⅱ/ LC3Ⅰ decreased， while the expression of P62 protein increased. Compared with the NAFLD-HCC group， the above indexes of mice were improved to different extents in the DOX group， LGZG group and DOX+LGZG group， and the intervention effect of DOX combined with LGZG were better than those of DOX. CONCLUSIONS LGZG combined with DOX can synergically promote the apoptosis of tumor cells， enhance the sensitivity of NAFLD-HCC chemotherapy， and effectively slow down the occurrence and development of NAFLD-HCC. The mechanism may be related to the regulation of autophagy in tumor cells.

Objective:To investigate the self-measured health status of college students in Tibet, and to construct the self-measured health scale (SRHMS V1.0) norm of College students in Tibet.Methods:This was a cross-sectional study. A multistage stratified sampling method was used. From April to June 2022, a total of 7 990 college students were selected from all colleges and universities in the Tibet Autonomous Region (7 in total). The self-rated health of Tibetan college students was investigated and evaluated by combining demographic information and SRHMS V1.0. Descriptive statistics, t-test, analysis of variance ( Brown-Forsythe test for unequal variance, LSD test for multiple comparisons), and Spearman correlation analysis were used to construct mean norm, percentile norm, and delimitation norm of physiological scale health (PSH), mental scale health (MSH), social scale health (SSH) score and total scale health (TSH) scores. Results:The total score of self-assessed health assessment among college students in Tibetan universities was (72.18±12.35). For different genders, the PSH, MSH, SSH and TSH scores were (73.85±13.78), (65.80±14.73), (69.85±16.00) and (73.44±12.77) for boys and (71.18±13.36), (62.81±14.03), (68.57±14.90) and (70.92±11.94) for girls, respectively. Scores on each subscale and total scale were statistically significant different between the different sexes ( t=2.531, 2.672, 1.867, 2.623, all P<0.05). For different grades, the PSH, MSH, SSH and TSH scores of the freshman were (73.36±13.23), (65.77±14.58), (70.98±15.60) and (73.51±11.91); the sophomore were (70.74±13.73), (62.40±13.60), (66.92±14.62) and (70.16±12.28), the junior were (75.48±13.09), (64.08±15.12), (71.90±15.12) and (74.10±12.36); and the senior were (67.21±14.41), (59.19±17.67), (64.91±18.59) and (66.94±14.59) respectively, with the differences in scores of each subscale and the total scale in different grades being statistically significant ( F=3.952, 3.611, 4.841, 5.583, all P<0.05). The mean norm, percentile norm and demarcation norm of the total score and each subscale of self-measured health of college students in Tibetan universities were constructed with gender and grade as the cut-off values. Conclusion:The model of self-measured health assessment scale for students in colleges and universities in Tibet is established, which can provide evaluation criteria for evaluating the health status of college students in Tibet and plateau areas.

Cohort Study Protocol: A Cohort of Korean Atomic Bomb Survivors and Their Offspring / 예방의학회지

In 1945, atomic bombs were dropped on Hiroshima and Nagasaki. Approximately 70 000 Koreans are estimated to have been exposed to radiation from atomic bombs at that time. After Korea’s Liberation Day, approximately 23 000 of these people returned to Korea. To investigate the long-term health and hereditary effects of atomic bomb exposure on the offspring, cohort studies have been conducted on atomic bomb survivors in Japan. This study is an ongoing cohort study to determine the health status of Korean atomic bomb survivors and investigate whether any health effects were inherited by their offspring. Atomic bomb survivors are defined by the Special Act On the Support for Korean Atomic Bomb Victims, and their offspring are identified by participating atomic bomb survivors. As of 2024, we plan to recruit 1500 atomic bomb survivors and their offspring, including 200 trios with more than 300 people. Questionnaires regarding socio-demographic factors, health behaviors, past medical history, laboratory tests, and pedigree information comprise the data collected to minimize survival bias. For the 200 trios, whole-genome analysis is planned to identify de novo mutations in atomic bomb survivors and to compare the prevalence of de novo mutations with trios in the general population. Active follow-up based on telephone surveys and passive follow-up with linkage to the Korean Red Cross, National Health Insurance Service, death registry, and Korea Central Cancer Registry data are ongoing. By combining pedigree information with the findings of trio-based whole-genome analysis, the results will elucidate the hereditary health effects of atomic bomb exposure.

Comparison of Proportional Mortality Between Korean Atomic Bomb Survivors and the General Population During 1992–2019

Background@#Atomic bombs dropped on Hiroshima and Nagasaki in Japan in August 1945 were estimated to have killed approximately 70,000 Koreans. In Japan, studies on the health status and mortality of atomic bomb survivors compared with the non-exposed population have been conducted. However, there have been no studies related to the mortality of Korean atomic bomb survivors. Therefore, we aimed to study the cause of death of atomic bomb survivors compared to that of the general population. @*Methods@#Of 2,299 atomic bomb survivors registered with the Korean Red Cross, 2,176 were included in the study. In the general population, the number of deaths by age group was calculated from 1992 to 2019, and 6,377,781 individuals were assessed. Causes of death were categorized according to the Korean Standard Classification of Diseases. To compare the proportional mortality between the two groups, the P value for the ratio test was confirmed, and the Cochran-Armitage trend test and χ 2 test were performed to determine the cause of death according to the distance from the hypocenter. @*Results@#Diseases of the circulatory system were the most common cause of death (25.4%), followed by neoplasms (25.1%) and diseases of the respiratory system (10.6%) in atomic bomb survivors who died between 1992 and 2019. The proportional mortality associated with respiratory diseases, nervous system diseases, and other diseases among atomic bomb survivors was higher than that of the general population. Of the dead people between 1992 and 2019, the age at death of survivors who were exposed at a close distance was younger than those who were exposed at a greater distance. @*Conclusion@#Overall, proportional mortality of respiratory diseases and nervous system diseases was high in atomic bomb survivors, compared with the general population. Further studies on the health status of Korean atomic bomb survivors are needed.

Allogeneic hematopoietic stem cell transplantation in acute leukemia patients with the SET-NUP214 fusion gene: Efficacy and survival analysis / 中华内科杂志

Objective: To investigate the clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for patients with acute leukemia who are positive for the SET-NUP214 fusion gene (SET-NUP214+AL). Methods: This was a retrospective case series study. Clinical data of 18 patients with SET-NUP214+AL who received allo-HSCT in the First Affiliated Hospital of Soochow University and Soochow Hongci Hematology Hospital from December 2014 to October 2021 were retrospectively analyzed to investigate treatment efficacy and prognosis. The Kaplan-Meier method was used for survival analysis. Results: Of the 18 patients, 12 were male and 6 were female, and the median age was 29 years (range, 13-55 years). There were six cases of mixed phenotype acute leukemia (three cases of myeloid/T, two cases of B/T, one case of myeloid/B/T), nine cases of acute lymphoblastic leukemia (ALL) (one case of B-ALL and eight cases of T-ALL), and three cases of acute myeloid leukemia. All patients received induction chemotherapy after diagnosis, and 17 patients achieved complete remission (CR) after chemotherapy. All patients subsequently received allo-HSCT. Pre-transplantation status: 15 patients were in the first CR, 1 patient was in the second CR, 1 was in partial remission, and 1 patient did not reach CR. All patients were successfully implanted with stem cells. The median time of granulocyte and platelet reconstitution was +12 and +13 days, respectively. With a median follow-up of 23 (4-80) months, 15 patients survived, while 3 patients died. The cause of death was recurrence of SET-NUP214+AL after transplantation. After allo-HSCT, 5 patients relapsed. The estimated 3-year overall survival (OS) and relapse-free survival (RFS) rates were 83.3%±15.2% and 55.4%±20.7%, respectively. Among the 15 patients who achieved CR before transplantation, there was no significant difference in OS and RFS between haploidentical HSCT and matched sibling donor HSCT (all P>0.05). Conclusions: Allo-HSCT can improve the prognosis and long-term survival rate of patients with SET-NUP214+AL. Disease recurrence is the most important factor affecting long-term survival.

Herbal textual research on Flos Trollii / 中国药房

Flos Trollii is a traditional Chinese medicinal herb in China. The 2020 edition of the Chinese Pharmacopoeia （part 1） did not include the medicinal herb， its source is not clear， and there is a lack of relevantly systematic and comprehensive research. By consulting ancient Chinese herbal medicines， medical books and related literature， the textual research of Flos Trollii was conducted to verify the name， origin and producing area， so as to provide a reference for the clinical application and resource development of Flos Trollii. Through textual research， it could be seen that the name “Jinlianhua” was used as the correct name in the mainstream origin of the past dynasties， and there were still multiple synonyms such as Hanjinlian， Jinmeicao and so on， most of which originated from its growth environment and appearance. According to the distribution of varieties， it could be inferred that the mainstream origin of Flos Trollii in the Qing Dynasty and before was Trollius chinensis Bge. According to historical records， Flos Trollii were mostly produced in northern regions such as Hebei， Inner Mongolia， Shanxi， etc.， which was related to the fact that Flos Trollii liked cloudy， humid and cold environments. Based on the textual research results， the author suggested that the mainstream origin of the past dynasties T. chinensis Bge. should be selected for subsequent collection of Flos Trollii.

Effects of cinepazide maleate injection on blood pressure in patients with acute ischemic stroke and hypertension / 中华内科杂志

Objective:To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection.Methods:This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes.Results:This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%, P>0.05) between cinepazide maleate group and control group. Conclusion:Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.

Preliminary exploration of the metabolic profile and metabolic pathways in newly diagnosed multiple myeloma / 中华肿瘤杂志

Objective: To explore the metabolite profile and metabolic pathways of newly diagnosed multiple myeloma (MM). Methods: Gas chromatography-mass spectrometry (GC-MS) was employed for the high-throughput detection and identification of serum samples from 55 patients with MM and 37 healthy controls matched for age and sex from 2016 to 2017 collected at the First Affiliated Hospital of Soochow University. The relative standard deviation (RSD) of quality control (QC) samples was employed to validate the reproducibility of GC-MS approach. The differential metabolites between patients with MM and healthy controls were detected by partial least squares discrimination analysis (PLS-DA), and t-test with false discovery rate (FDR) correction. Metabolomics pathway analysis (MetPA) was employed to construct metabolic pathways. Results: There were 55 MM patients, including 34 males and 21 females. The median age was 60 years old (42-73 years old). There were 30 cases of IgG type, 9 cases of IgA type, 1 case of IgM type, 2 cases of non-secreted type, 1 case of double clone type and 12 cases of light chain type, including 3 cases of kappa light chain type and 9 cases of lambda light chain type. The result of QC sample test showed that the proportion of compounds with the RSD of the relative content of metabolites < 15% was 70.21% obtained by the reproducibility of GC-MS experimental data, which implied that the experimental data were reliable. A total of 17 metabolites were screened differently with the healthy control group, including myristic acid, hydroxyproline, cysteine, palmitic acid, L-leucine, stearic acid, methionine, phenylalanine, glycerin, serine, isoleucine, tyrosine, valine, citric acid, inositol, threonine, and oxalic acid (VIP>1, P<0.05). Metabolic pathway analysis suggested that metabolic disorders in MM patients comprised mainly phenylalanine metabolism, glyoxylic acid and dicarboxylic acid metabolism, phosphoinositide metabolism, cysteine and methionine metabolism, glycerolipid metabolism, glycine, serine, and threonine metabolism. Conclusion: Compared with normal people, patients with newly diagnosed MM have obvious differences in metabolic profiles and metabolic pathways.

Analysis of clinical phenotype and genotype of Chinese children with disorders of sex development / 中华儿科杂志

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

AIM:To observe the clinical effect of ranibizumab combined with 577nm micropulse laser in the treatment of severe diabetic macular edema(DME). METHODS:There were 52 eyes of 52 patients diagnosed with severe DME who admitted to the People's Hospital of Guangxi Zhuang Autonomous Region from June 2016 to September 2019. The patients were randomly divided into the observation group(26 patients with 26 eyes, treated with ranibizumab combined with 577nm micropulse laser)and the control group(26 patients with 26 eyes, treated with ranibizumab alone). Patients in both groups received intravitreal injection of ranibizumab with “3+PRN” regimen. Followed up at 9mo after treatment to observe the central macular thickness(CMT), the best corrected visual acuity(BCVA)and the times of intravitreal injection of ranibizumab in the two groups.RESULTS:Compared with before treatment, the CMT and BCVA of the two groups were significantly improved at each time point after treatment(all P<0.001), but there was no difference between the two groups(P>0.05). During the follow-up period, the times of vitreous injection of ranibizumabin the observation group was significantly less than that in the control group(5.88±1.24 times vs 7.12±1.24 times, P=0.001). CONCLUSION:Both ranibizumab combined with 577nm micropulse laser and ranibizumab alone are effective in reducing edema and improving vision in patients with severe DME, but the combination therapy reduces the times of injection.

Efficacy and safety of cinepazide maleate injection in acute ischemic stroke patients with obvious motor function deficit / 中华神经科杂志

Objective:To confirm the efficacy and safety of cinepazide maleate injection in acute ischemic stroke patients with obvious motor function deficit.Methods:This study is a subgroup analysis of multi-center, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial. A total 812 patients of acute ischemic stroke with obvious limb motor deficit [motor function of limbs score in National Institutes of Health Stroke Scale (NIHSS) ≥4] were enrolled in this subgroup analysis. Patients received either cinepazide maleate injection or placebo. The treatment period was 14 days and follow-up was 90 days. The efficacy endpoints included the proportions of patients with a modified Rankin Scale (mRS) score ≤2, mRS score ≤1 and Barthel Index <95 on day 90. Safety was evaluated by recording all adverse events, monitoring vital signs, laboratory parameters and electrocardiogram.Results:A total of 732 patients were involved in the final efficacy analysis (361 in cinepazide maleate group and 371 in control group). The baseline limb motor function score of NIHSS was 5.23±1.43 in the cinepazide maleate group whereas 5.20±1.36 in the control group. Logistic regression analysis showed that following treatment for 90 days, the proportion of patients with a mRS score ≤2 was significantly higher in the cinepazide maleate group than in the control group [56.0% (202/361) vs 44.2% (164/371), OR=0.60, 95% CI 0.44-0.82, P=0.002]. The proportion of patients with a mRS score ≤1 was higher in the cinepazide maleate group than in the control group [43.3% (139/361) vs 35.2% (118/371), OR=0.69, 95% CI 0.50-0.97, P=0.031]. The proportion of patients with a Barthel Index <95 on day 90 was significantly lower in the cinepazide maleate group than in the control group [45.2% (145/361) vs 55.2% (185/371), OR=0.64, 95% CI 0.46-0.88, P=0.007]. During the treatment and follow-up period, the incidence of the most common adverse events in the cinepazide maleate group was 50.4% (199/395). Constipation and abnormal liver function were more common, but there were no statistically significant differences between the two groups. Conclusion:Cinepazide maleate injection is superior to placebo in improving neurological function and activities of daily living, reducing disability, and promoting functional recovery and safe in patients with acute ischemic stroke with obvious limb motor deficit.

The inhibitory effect of Ruyizhenbao tablets on osteoarthritis pain / 中国药理学通报

Aim To investigate whether and how Huy- izhenbao tablets regulated osteoarthritis pain.Methods We transected the meniscotibial ligament of mice, which caused osteoarthritis by destabilizing the medial meniscus ( DMM).Different doses of Huyizhenbao tablets (12.5,25,50 mg • kg-1) were administered intragastrically.Dynamic and static mechanical allo- dynia were measured.The spinal cord slices were pre¬pared to record miniature excitatory postsynaptic cur-rents (niEPSCs) and miniature inhibitory postsynaptic currents (mlPSCs) by using patch clamp electrophysi¬ological recordings.The phosphorylation of NMDA re¬ceptor ( N-methyl-D-aspartate receptors) (rluNl sub- unit at S897 residue ( pS897-GluNl ) was observed by immunohistochemistry.Results Huyizhenbao tablets dose-dependently attenuated the dynamic and static mechanical allodynia induced by DMM, reduced the frequency of niEPSCs and inhibited the pS897-GluNI level.Huyizhenbao tablets had no effects on mlPSCs.Conclusions Huyizhenbao tablets effectively alleviate osteoarthritis pain by blocking the presynaptic release of excitatory transmitter glutamate and inhibiting the phosphorylation of NMDA receptor in spinal cord dorsal horn.

The regulating effect of Collybistin on Neuropathic Pain / 中国药理学通报

Aim To investigate the role of collybistin in the regulation of pain transmission. Methods The distribution of collybistin in spinal cord was observed by immunohistochemical staining. The role of collybis¬tin in pain transmission was evaluated by behavioral experiments. The effect of collybistin on inhibitory synap¬tic transmission was studied by electrophysiological ex¬periments. Results Collybistin was distributed in spi¬nal cord neurons; ShRNA-collybistin induced pain sen-sitization of intact mice ( P < 0. 05 ) . Overexpression of collybistin in spinal cord significantly alleviated pain sensitization induced by peripheral nerve injury ( P <0. 05 ) . ShRNA-collybistin also significantly reduced the amplitudes and frequencies of miniature inhibitory postsynaptic currents (mlPSCs) in superficial neurons of spinal cord dorsal horn (P <0. 05) . Overexpression of collybistin in spinal cord could reverse the effects of peripheral nerve injury on mlPSCs (P <0. 05). Con¬clusions Collybistin is involved in pain sensitization induced by peripheral nerve injury in mice.
