ObjectiveTo investigate the clinical efficacy and safety of iguratimod combined with the Chinese medicine Runzaoling in the treatment of primary Sjögren's syndrome （pSS）. MethodSeventy-two patients treated in the Department of Rheumatology and Immunology of the Second Affiliated Hospital of Guizhou University of Traditional Chinese Medicine（TCM） from January 2021 to June 2022 who met the Western medical diagnosis of pSS and had the TCM syndrome of Yin deficiency and heat toxin syndrome were randomly assigned into an observation group and a control group， with 36 patients in each group. The observation group was treated with iguratimod combined with Runzaoling， and the control group was treated with iguratimod. The treatment in both groups lasted for 12 weeks. The clinical symptoms， EULAR Sjogren's syndrome patient reported index （ESSPRI）， EULAR Sjögren's syndrome disease activity index （ESSDAI）， erythrocyte sedimentation Rate （ESR）， C-reactive protein （CRP）， immunoglobulin （IgG）， Schirmer score， and saliva flow of the two groups were determined before and after treatment. Furthermore， the incidence of adverse reactions was compared between the two groups. ResultThe total response rate in the observation group was 75.0% （27 patients with response and 9 patients with no response）， which was higher than that （61.11%， 22 patients with response and 14 patients without response） in the control group （P<0.05）. After treatment， the ESSPRI， ESSDAI， and TCM syndrome scores in both groups decreased and the decreases were more obvious in the observation group than in the control group （P<0.05）. The treatment in both groups recovered the ESR， CRP， IgG， Schirmer score， and saliva flow （P<0.05）. Moreover， the observation outperformed the control group in terms of the ESR， CRP， IgG， and saliva flow （P<0.05） and had no significant difference in the Schirmer score compared with the control group. During the treatment period， 2 patients in the observation group had nausea， and 1 patient had an abnormal liver function， which were relieved after symptomatic treatment and did not affect the treatment. In the control group， 1 patient withdrew from the study due to rashes and showed no special discomfort in the follow-up 4 weeks， and 1 patient had nausea， which was relieved after symptomatic treatment. ConclusionIguratimod combined with Runzaoling has good clinical efficacy and safety in the treatment of pSS.

Objective To explore the medication rules of Professor ZHONG Guang-Ling's prescriptions for the treatment of lumbar disc herniation(LDH)based on data mining method,so as to provide reference for the treatment of LDH with Chinese medicine.Methods The prescriptions for the effective cases of outpatients of LDH treated by Professor ZHONG Guang-Ling in the recent 5 years were collected.The medication frequency of Chinese medicines in the included prescriptions and the distribution of their properties,flavors and meridian tropism were investigated.Moreover,the association rule analysis and cluster analysis of the high-frequency drugs were carried out.Results A total of 164 prescriptions were included and 168 Chinese medicines were used.The top 10 high-frequency drugs in descending order were Achyranthis Bidentatae Radix,Chuanxiong Rhizoma,Pheretima,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,Gentianae Macrophyllae Radix,Angelicae Sinensis Radix,Rehmanniae Radix Praeparata,Persicae Semen,Cyperi Rhizoma,and Carthami Flos.The properties of the prescribed drug were mainly warm and mild in nature,and bitter and pungent in flavor,and mainly had the meridian tropism of the liver,kidney and spleen meridians.According to the therapeutic actions,the drugs were mainly categorized as deficiency-supplementing drugs,dampness-removing and collateral-unblocking drugs,and blood-activating and stasis-removing drugs.The results of association rule analysis yielded 10 drug pairs,and cluster analysis yielded 6 core drug combinations.Conclusion For the treatment of LDH,Professor ZHONG Guang-Ling usually adopts the Chinese medicine for supplementing the deficiency and supporting healthy-qi,together with the medicines for nourishing the liver and kidney and regulating the spleen and stomach from the perspective of liver,kidney and spleen.Moreover,therapy of activating blood and removing stasis is also stressed,pathogen-eliminating medicines for removing dampness,unblocking collaterals and clearing heat are used based on syndrome differentiation,and then simultaneous application of purging and nourishing therapeutics is achieved through the utilization of purging method after supplementing method.

Synergistic Effect of Hydrogen and 5-Aza on Myogenic Differentiation through the p38 MAPK Signaling Pathway in Adipose-Derived Mesenchymal Stem Cells

Background and Objectives@#This study aims to clarify the systems underlying regulation and regulatory roles of hydrogen combined with 5-Aza in the myogenic differentiation of adipose mesenchymal stem cells (ADSCs). @*Methods@#and Results: In this study, ADSCs acted as an in vitro myogenic differentiating mode. First, the Alamar blue Staining and mitochondrial tracer technique were used to verify whether hydrogen combined with 5-Aza could promote cell proliferation. In addition, this study assessed myogenic differentiating markers (e.g., Myogenin, Mhc and Myod protein expressions) based on the Western blotting assay, analysis on cellular morphological characteristics (e.g., Myotube number, length, diameter and maturation index), RT-PCR (Myod, Myogenin and Mhc mRNA expression) and Immunofluorescence analysis (Desmin, Myosin and β-actin protein expression). Finally, to verify the mechanism of myogenic differentiation of hydrogen-bound 5-Aza, we performed bioinformatics analysis and Western blot to detect the expression of p-P38 protein. Hydrogen combined with 5-Aza significantly enhanced the proliferation and myogenic differentiation of ADSCs in vitro by increasing the number of single-cell mitochondria and upregulating the expression of myogenic biomarkers such as Myod, Mhc and myotube formation. The expressions of p-P38 was up-regulated by hydrogen combined with 5-Aza. The differentiating ability was suppressed when the cells were cultivated in combination with SB203580 (p38 MAPK signal pathway inhibitor). @*Conclusions@#Hydrogen alleviates the cytotoxicity of 5-Aza and synergistically promotes the myogenic differentiation capacity of adipose stem cells via the p38 MAPK pathway. Thus, the mentioned results present insights into myogenic differentiation and are likely to generate one potential alternative strategy for skeletal muscle related diseases.

Reservation versus sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear / 中华创伤骨科杂志

Objective:To compare the clinical efficacy between reservation and sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear.Methods:A retrospective study was conducted to analyze the clinical data of 32 patients with rotator cuff tear plus remnants in the footprint area (2 cm < tear size <5 cm) who had been admitted to Department of Sports Medicine, The People's Hospital of Northern Jiangsu from May 2020 to July 2021. The patients were divided into 2 groups according to reservation or sacrifice of remnants in the footprint area in arthroscopic repair of rotator cuff tear. In the remnant-reservation group (16 cases): 5 males and 11 females with an age of (61.8±9.9) years, 9 left and 7 right shoulders affected, and (3.7±1.1) cm in size of rotator cuff tear; in the remnant-sacrifice group (16 cases): 4 males and 12 females with an age of (61.3±8.8) years, 8 left and 8 right shoulders affected, and (3.9±0.9) cm in size of rotator cuff tear. The 2 groups were compared in terms of visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley shoulder function score (Constant score), and range of motion of the affected shoulder before surgery, 3 months after surgery and at the last follow-up. The ratio of bilateral abductor muscle strengths (affected side/healthy side) was analyzed and compared between the 2 groups, and the healing of the rotator cuff was evaluated by MRI at the last follow-up.Results:The 2 groups were comparable because there were no significant differences in all their preoperative demographic data ( P>0.05). The 32 patients were followed up for (14.3±3.5) months after surgery. At 3 months after surgery, the VAS score in the remnant-reservation group [1.0 (0.0,1.0) point] was significantly lower than that in the remnant-sacrifice group [1.0 (1.0,1.0) point] ( P<0.05), but there was no significant difference between the 2 groups in ASES score, Constant score or range of motion of the affected shoulder ( P>0.05). At the last follow-up, the ASES score, forward flexion, abduction and ratio of bilateral abductor muscle strengths (affected side/healthy side) in the remnant-reservation group [(96.1±4.8) points, 170.0 (170.0,170.0)°, 160.0 (160.0,170.0)°, and 85.5%±13.8%]were significantly better than those in the remnant-sacrifice group [(91.4±5.9) points, 160.0 (160.0,170.0)°, 150.0 (140.0,155.0)°, and 72.6%±16.9%] ( P < 0.05), but there were no statistically significant differences between the 2 groups in VAS score, Constant score, neutral external rotation angle, or body-side internal rotation ( P>0.05). The Sugaya grading for MRI rotator cuff healing was significantly different between the 2 groups at the last follow-up ( P<0.05). Conclusion:In arthroscopic repair of rotator cuff tear, reservation of remnants in the footprint area can significantly relieve postoperative shoulder pain, and has obvious advantages in restoration of shoulder forward flexion, abduction and abductor muscle strength, leading to better healing of the rotator cuff and the large nodule than the remnant-sacrifice technique.

Objective:To investigate the role of depth of anesthesia monitoring in predicting postoperative cognitive impairment in elderly cancer patients.Methods:The clinical data of 70 elderly cancer patients in Shanxi Province Cancer Hospital from February 2020 to February 2021 were retrospectively analyzed. According to the postoperative cognitive function, they were divided into the postoperative cognitive impairment group (20 cases) and the normal postoperative cognitive function group (50 cases). Statistical analyses of the mini mental state examination (MMSE) score of cognitive function, mean arterial pressure (MAP) and bispectral index score (BIS) before anesthesia (T 0), before skin incision (T 1), 1 h after skin incision (T 2), 2 h after skin incision (T 3), at the completion of surgery (T 4), and at the time point of extubation (T 5), as well as the levels of interleukin-6 (IL-6) and central nervous specific protein (S100-β) at 1 d before operation, immediately after surgery and 1 d after surgery between the two groups were performed. Results:The MMSE score of patients in the postoperative cognitive impairment group was lower than that in the normal postoperative cognitive function group [(21±3) points compared with (25±5) points], and the difference between the two groups was statistically significant ( t = 2.98, P < 0.05). The MAP of the two groups at T 1, T 2, T 3, T 4, and T 5 gradually increased (both P < 0.05), the MAP at T 1, T 2, T 3, T 4 was lower than that at T 0 (all P < 0.05), and the MAP at T 5 was higher than that at T 0 (both P < 0.05). There were no statistical differences in MAP between the two groups at T 0, T 1, T 2, T 3, T 4, and T 5 (all P > 0.05). BIS values of the two groups at T 0, T 1, T 2, and T 3 gradually decreased (both P < 0.05), BIS values at T 4 and T 5 gradually increased (both P < 0.05). At T 2 and T 3, BIS value of the postoperative cognitive impairment group was lower than that of the normal postoperative cognitive function group (both P < 0.05). The duration of BIS < 45 in the postoperative cognitive impairment group was longer than that in the normal postoperative cognitive function group [(44.1±7.7) min than (12.6±2.2) min], and the difference between the two groups was statistically significant ( t = 26.68, P < 0.001). The levels of IL-6 and S100-β in the two groups were gradually increased 1 d before surgery, immediately after surgery and 1 d after surgery (both P < 0.05). On the 1st day after surgery, the S100-β level in the postoperative cognitive impairment group was higher than that in the normal postoperative cognitive function group ( P < 0.05). Conclusions:The application of depth of anesthesia monitoring is of high value in predicting postoperative cognitive impairment in elderly cancer patients.

Method:A total of 352 convalescent patients with CI differentiated into stoke involving meridians and collaterals due to wind-phlegm-static blood obstructing vessels in traditional Chinese medicine （TCM） were included in this multi-center， randomized， double-blind， single-simulated， Naoshuantong capsule-controlled clinical trial， which lasted from 28 December， 2016 to 12 April， 2019. After being randomized into an experimental group and a control group at a ratio of 3∶1， patients in the experimental group were provided with oral Tiandan Tongluo capsule， five capsules per time， three times per day， whereas those in the control group received both Naoshuantong capsule simulator， two capsules per time， three times per day， and Naoshuantong capsule， three capsules per time， three times per day， for 12 successive weeks. The patients were followed up until 180 days after onset. The Barthel activities of daily living （ADL） index （BI） score was used as the primary outcome， and the secondary outcomes included neurological deficit score ［assessed with National Institutes of Health Stroke Scale （NIHSS）］， modified Rankin scale （mRS）， TCM syndrome score， and proportion of patients with new vascular events. The changes in laboratory indexes and the incidence of adverse reactions during treatment were observed. Result:Among the 389 cases enrolled， 30 dropped out， with the drop-out rate being 7.71%. There were 374 cases included in the full analysis set and 377 in the safety set. The comparison with the control group revealed that the total BI score and the percentage of BI score ≥ 75 in the experimental group were increased， but the difference was not statistically significant. The percentage of mRS score ≤ 2 within 180 days after onset in the experimental group obviously elevated in contrast to that of the control group （<italic>P</italic><0.05）. As demonstrated by TCM syndrome score analysis， the markedly effective rate in the experimental group was significantly higher than that in the control group （<italic>P</italic><0.05）. During the trial， the incidence rates of new vascular events in the experimental group and the control group were 0.00% and 1.09% （one case）， respectively， exhibiting no statistically significant difference between the two groups. Conclusion:Tiandan Tongluo capsule and Naoshuantong capsule both produce definite therapeutic effects in the treatment of CI in convalescence （stoke involving meridians and collaterals due to wind-phlegm-static blood obstructing vessels）. Compared with Naoshuantong capsule， Tiandan Tongluo capsule better alleviates neurological deficit， promotes neural functional recovery， and improves TCM syndrome score， without inducing severe adverse reactions.

Objective:To investigate the effects of attention and interpretation therapy on fatigue and sleep quality in patients with gastrointestinal tumor during chemotherapy.Methods:From December 2018 to December 2019, eighty-four patients with gastrointestinal tumor hospitalized in two hospitals (third-grade class-A) in Ningxia were selected as the research objects. According to the random number table, they were divided into the control group and the observation group with 42 cases in each group. Patients in the two groups received routine care. On this basis, the observation group received 10 weeks of attention and interpretation therapy. Cancer patients fatigue scale and Pittsburgh sleep quality index(PSQI) scale were used to evaluate before intervention, 10 weeks after intervention and 3 months after intervention. SPSS 17.0 software was used for statistical analysis. Independent sample t-test and repeated measure analysis of variance were used for comparison between groups. Results:(1) The time effect, inter group effect and interaction effect of fatigue total scores and each dimension score of the two groups were significant (all P<0.01). Further simple effect analysis showed that there were significant differences in the total score and each dimension score of fatigue between the control group and the observation group at 10 weeks after intervention and 3 months after intervention (all P<0.01). (2) The time effect, inter group effect and interaction effect of PSQI total score, sleep quality, sleep time, sleep disorder score were significant (all P<0.01), but the time effect, inter group effect and interaction effect of sleep efficiency, daytime dysfunction and hypnotic drug use score were not significant (all P>0.05). Further simple effect analysis showed that there were significant differences in PSQI total score, sleep quality, sleep time, sleep time and sleep disorder scores between the control group and the observation group 10 weeks after the intervention(PSQI total score (6.83±2.46) vs (10.79±1.01); sleep quality (1.00±0.22) vs (1.24±0.82); sleep time (0.91±0.26) vs (1.40±0.86); sleep time (1.00±0.20) vs (2.02±0.72); sleep disorder (0.79±0.22) vs (1.60±0.59) and 3 months after the intervention(all P<0.01). Conclusion:Attention and interpretation therapy can effectively alleviate the fatigue of gastrointestinal tumor patients during chemotherapy, and improve sleep quality.

Lipids, Anthropometric Measures, Smoking and Physical Activity Mediate the Causal Pathway From Education to Breast Cancer in Women: A Mendelian Randomization Study / 한국유방암학회지

Purpose@#We aimed to investigate whether obtaining a higher level of education was causally associated with lower breast cancer risk and to identify the causal mechanism linking them. @*Methods@#The main data analysis used publicly available summary-level data from 2 large genome-wide association study consortia. Mendelian randomization (MR) analysis used 65 genetic variants derived from the Social Science Genetic Association Consortium as instrumental variables for years of schooling. The outcomes from the Breast Cancer Association Consortium (BCAC) were the overall breast cancer risk (122,977 cases/105,974 controls in women) and the two subtypes: estrogen receptor (ER)-positive breast cancer and ER-negative breast cancer. Fixed and random effects inverse variance weighted methods were used to estimate the causal effects, along with other additional MR methods for sensitivity analyses. @*Results@#Results showed that each additional standard deviation of 4.2 years of education was causally associated with a 27% lower risk of ER-negative breast cancer (odds ratio, 0.73; 95% confidence interval, 0.64–0.84; p-value 10 minutes explain a small part of the causal effect of education on the risk of developing breast cancer, and their mediation proportion is approximately 1%. @*Conclusion@#A low level of education is a causal risk factor in the development of breast cancer as it is associated with poor lipid profile, obesity, smoking, and types of physical activity.

Exploring the causal relationship between hip circumference and type 2 diabetes based on mendelian randomization / 中华疾病控制杂志

Objective To investigate the causal association between hip circumference (HC) and type 2 diabetes mellitus (T2DM) based on Mendelian randomization. Methods The genetic variants data of the HC and T2DM from the Genetic Investigation of Anthropometric Traits (GIANT) and DIAbetes Genetics Replication And Meta-analysis (DIAGRAM) database were matched according to the single nucleotide polymorphism (SNP) rsID. Genetic loci strongly related to the HC were used as instrumental variables; and the inverse-variance weighting, MR-Egger regression model and weighting median method were carried out to analyze the causal effect of HC on T2DM. Results Fifty-two, nine and fifteen SNPs were matched in the total cohort, female cohort and male cohort, respectively. Heterogeneity test suggested the SNPs were homogeneous. We found HC to be positively associated with T2DM risk (OR=1.065, 95% CI: 1.030-1.100, OR=1.103, 95% CI: 1.057-1.150 and OR=1.583, 95% CI: 1.273-1.968, respectively) in above three cohorts, respectively. Sensitivity analysis showed the results were robust. Conclusions There is a relationship between HC and T2DM of people, and HC may be the risk factor of T2DM.

According to the preoperative condylar condition. There were divided into smooth group and non-smooth group, the lateral cephalometric films 1 week (T0), 3 months (T1), 6 months (T2) and 1 year (T3) after surgery were used to establish the coordinate system and cephalometric analysis to determine the stability of the jaw after operation. The three-dimensional model of the condyle was segmented by cone beam computed tomography (CBCT) 1 week (T0), 3 months (T1), 6 months (T2) and 1 year (T3) after surgery and the volume was obtained to evaluate the change of the condyle volume after surgery. CBCT image data was used to evaluate the changes of the condylar condition after surgery, and to clarify the correlation between the postoperative condylar condition and jaw stability. SPSS 20.0 statistical software was used for statistical analysis, Fisher's exact probability methods were used to compare whether there were statistically significant differences in the stability of the mandibular joint at stages T1, T2 and T3 with different preoperative condylar condition.Spearman correlation coefficient analysis and Mann-Whitney test were used to compare whether there were statistically significant differences in the volume changes at stages T1, T2 and T3 after surgery between the two groups.@*RESULTS@#The recurrence rates of the mandible in the condylar smooth group were T1 36.85%, T2 47.37% and T3 42.11%, respectively. The recurrence rates in the non-smooth condylar group were T1 27.78%, T2 44.44% and T3 55.56%, respectively. There was no statistical difference in the recurrence rates between the two groups at different time points. There was no significant difference in the condylar volume change between smooth group and non-smooth group.@*CONCLUSION@#For patients with mandible retrognathism deformities with severe temporomandibular joint osteoarthrosis and no significant changes in the condyle observed for one year before surgery, there is no difference in the influence of the preoperative condylar condition on the stability of jaw after operation, and no definite influence on the volume of the condyle after operation. Condylar resorption 3 months after surgery can cause instability of the jaw after orthognathic surgery.

Prenatal diagnosis and pregnancy outcomes of sixty-three fetuses with tetralogy of Fallot / 中华妇产科杂志

Objective To analyze the pregnancy outcomes of fetal tetralogy of Fallot and to explore its prenatal diagnosis and treatment procedures. Methods The clinical data of 63 cases of fetal tetralogy of Fallot (62 cases were singleton and 1 case was one of twin) were collected retrospectively from November, 2013 to November, 2017 in Beijing Obstetrics and Gynecology Hospital. Results (1) Totally, 63 cases out of 46 352 pregnancies were diagnosed fetal tetralogy of Fallot by fetal ultrasonic cardiogram with about 0.136%(63/46 352) occurrence rate, and the mean gestational age was (23±3) weeks. And 50 cases (79%, 50/63) terminated pregnancy by induced labour. (2) Totally, 57 cases (90%,57/63) accepted genetic diagnosis.Eight cases (13%, 8/63) existed chromosome abnormality including 21-trimosy in 6 cases, 18-trisomy in 1 case and 22q11.2 microdeletion syndrome in 1 case; and these 8 cases were determined before 28 gestational weeks. (3) And 13 cases (21%, 13/63) of no fetal genetic abnormality selected to continue pregnancy. Twelve cases underwent full term delivery (5 cases were cesarean section delivery and 7 cases were vaginal delivery). Twelve newborns underwent surgical radical operation on heart malformation and got recovery. One case underwent preterm cesarean section at 35 gestational weeks for one of twin, and the newborn with tetralogy of Fallot was dead. The other the newborns survived and were followed up for tetralogy of Fallot surgery from 1 month to 3 years old after birth and recovered.Conclusions Fetal tetralogy of Fallot mainly is diagnosed by ultrasonic cardiogram in the second trimester. The gestational age of diagnosis may be as early as 15 gestational weeks. Fetal tetralogy of Fallot with no genetic abnormality could underwent radical heart malformation operation after birth. It is necessary to undergo genetic testing on fetal tetralogy of Fallot and prenatal multidisciplinary counseling as well.

Effect of Sulfur Fumigation on Content of Chemical Constituents in Panacis Quinquefolii Radix and Preliminary Study on Its Identification Method / 中国实验方剂学杂志

Objective: To elucidate the effect of sulfur fumigation on the content of chemical composition and quality of Panacis Quinquefolii Radix, and to discuss the identification method of sulfur fumigated Panacis Quinquefolii Radix. Method: The content changes of ginsenoside Rb1, Re, Rg1 in Panacis Quinquefolii Radix were determined by HPLC-DAD before and after sulfur fumigation. The content changes of 11 inorganic elements in Panacis Quinquefolii Radix before and after sulfur fumigation were detected by microwave digestion method and inductively coupled plasma emission spectrometry tandem mass spectrometry (ICP-MS). The quality difference of Panacis Quinquefolii Radix before and after sulfur fumigation was qualitatively distinguished combined with the principal component analysis. Result: Three ginsenosides were well separated and showed good linearity with R2 ≥ 0.999.Before sulfur fumigation, the contents of ginsenoside Rg1, Re and Rb1 in Panacis Quinquefolii Radix were (0.897±0.045), (13.092±0.639), (12.896±0.430) g ·kg-1, respectively. After sulfur fumigation, the contents of these three components in Panacis Quinquefolii Radix were (0.807±0.032), (11.968±0.627), (11.752±0.696) g ·kg-1, respectively. After fumigation, the contents of inorganic elements (Cr, Mn, Co, Cu, As, Se, Ag, Cd, Sb, Pb and Fe) from Panacis Quinquefolii Radix increased in varying degrees. According to the distribution results of three-dimensional (3D) scattered points, sulfur and non-sulfur fumigation products of Panacis Quinquefolii Radix could be effectively distinguished. Conclusion: After sulfur fumigation, the contents of ginsenoside Re and Rb1 in Panacis Quinquefolii Radix decrease significantly, but the contents of 11 inorganic elements increase, suggesting that sulfur fumigation may have a great influence on the quality of Panacis Quinquefolii Radix.
