Objective To investigate changes in serum level of glial fibrillary acidic protein (GFAP) in patients with Parkinson disease (PD) and its clinical significance. Methods Serum GFAP was determined with sandwich ELISA for 82 patients with PD and acute cerebral infarction (ACI), as well as healthy normal controls. Patients with PD were then divided into two sub-groups in terms of their course duration, one with less than five years and the other with more than or equal to five years. Effects of course duration and age of the patients on their serum GFAP were analyzed. Results Serum level of GFAP was significantly higher in patients with PD [(1.628±0.104) μg/L] and ACI [(1. 637±0. 063 )μg/L] than that in healthy normal controls [ (0. 025±0. 003)μg/L, t = 82. 7, 142. 2, all P <0. 05 ]. But, there was no significant difference in serum GFAP between patients with PD and ACI ( t =0. 214, P > 0. 05 ). Serum level of GFAP in PD patients had no significant correlation with their age. There was no significant difference in serum GFAP between two sub-groups of patients with PD (P > 0.05 ). Conclusions Serum level of GFAP increased significantly in PD patients, as compared to healthy normal controls, but it is not specific. Serum GFAP in patients with PD maintained at certain high level with progression of the disease, indicating effect of astrocytes may persistently exist during the disease course.

OBJECTIVE: To study the association between superior mesenteric artery hemodynamic indexes and scores of lower gastrointestinal symptoms rating scales(LGSRS) in patients with type 2 diabetic mellitus. METHODS: Totally 142 inpatients with type 2 diabetes with average age of 58.76±12.32 yrs were enrolled, who were treated from August 2016 to March 2018. The history, gender, age,course and BMI were recorded, and fasting blood glucose(FBG), glycosylated hemoglobin(HbA1c), 2-hour postprandial blood glucose(PBG), total cholesterol(TC), triglyceride(TG), urine ACR and LGSRS were determined. Ultrasonic scanning of mesenteric artery was performed for hemodynamic indexes, including artery inner diameter(ID), peak systolic velocity(PSV), end-diastolic velocity(EDV), and resistance index(RI)at starting part,first level branch, and second level branch from root of the superior mesenteric artery(SMA).Patients were divided into 2 groups according to their LGSRS, 74 patients with LGSRS≥6 were in positive group, and 68 patients with LGSRS<6 were in control group. RESULTS: 1. There were no significant differences between the 2 groups in gender, BMI, HbA1C, FBG, PBG,TC or TG(P>0.05), but the age and DD were significantly higher in positive group than in control group(P<0.05). 2. There were three patients(4.41%) who had atheroma or plaques in SMA in control group, while five patients in positive group(6.76%)(P>0.05). 3. There were no significant difference between positive group and control group in ID at starting part and first level branch of SMA, while ID at second level branch was significantly increased in positive group compared with control group [(3.83±0.85)mm vs.(3.53±0.90)mm, P<0.05)].4. RI at first(0.816±0.059 vs 0.842±0.063,P<0.05) and second level branch(0.813±0.076 vs 0.845±0.073, P<0.05) and PSV at first level branch[(110.89±46.89)cm/s vs(95.72±36.59)cm/s,P<0.05] were significantly high in positive group; there were no difference in other hemodynamic indexes between the groups. 5.Adjusted by age,DD,glycemic and lipidemic profile,Logistic regression showed that ID at first(RR=2.092,95%CI 1.080-4.050,P=0.029) and second level branch(RR=0.491,95%CI 0.252-0.955,P=0.36) and EDV at second level branch(RR=0.897,95%CI 0.824-0.976,P=0.012) were independent factors influencing LGSRS(P<0.05). CONCLUSION: Ultrosonic hemodynamic abnormalities in the superior mesenteric artery might be important factor in development of lower gastrointestinal tract symptoms in patients with type 2 diabetes.

BACKGROUND:Hepatocyte transplantation has attracted more and more attention as a therapeutic measure for liver failure and genetic metabolic liver diseases.OBJECTIVE:TO evaluate the efficacy and safety of human hepatocyte transplantation in treating hepatitis B related liver failure in one case by a 2-year follow-up.DESIGN:A case-report of 2-year follow-up.SETTING:No.9 Department of Infectious Diseases,Bioengineering Research Room,the 302 Hospital of Chinese PLA.PARTICI PANT:One inpatient with hepatitis B related liver failure was selected from the 302 Hospital of Chinese PLA.and she was diagnosed according the laboratory tests.The transplanted hepatocytes were originated frOm the healthy liver of a 24-year-old man,who had signed the protocol for liver donation before death.METHODS:The hepatocyte transplantation was completed in the Department of Radiology,the 302 Hospital of Chinese PLA in December 2004.Liver was isolated to obtain human primary hepatocytes, and then cryopreserved.The hepatocytes were transplanted into recipient spleen via femoral vein after resuscitation.The clinical symptoms,changes of blood biochemical indexes,and changes of spleen MRI signals were observed before and after operation.The patient was reexamined every half a year after operation, including liver function, blood coagulation function,B-mode ultrasonography,gastroscopy and MRI,and she was followed up for 2 years. MAIN OUTCOME MEASURES:Liver function,blood coagulation function, imaging indexes, immunological indexes,complication and rejection.RESULTS:①Totally(1-2)×1010 hepatocytes were harvested,and the viability of rewarmed hepatocytes was 60%,and finally 2×109 hepatocytes were transplanted.②Two months later,the clinical symptoms of the recipient were obviously ameliorated,and serum bilirubin and aspartate aminotransferase(AST)were obviously decreased,while prothrombin activity was markedly increased.20 months later,the MRI results showed that there was hepatocyte image in spleen.Two years after operation.the total bilirubin level was 20 μmol/L,direct bilirubin level was 7 μmol/L, alanine aminotransferase was 416.75 nkat/L,AST was 533.44 nkat/L,albumin was 37 g/L,prothrombin activity was 90%,which were all obviously ameliorated as compared with those before operation(474.5 μmol/L,340.3 μmol/L,400.08 nkat/L,1 200.24 nkat/L,38 g/L,25%).The patient left the hospital 2 months later and could do light-burdened job.No complications of hydroperitonia and liver function failure, etc.were observed,and no rejection occurred.Several reexaminations by B-mode ultrasonography all indicated the further aggravations of liver cirrhosis and esophageal varices.She was admitted to hospital for twice because of esophageal varices bleeding,and cured by endoscopic variceal sclerosis therapy.CONCLUSION:Hepatocyte transplantation can ameliorate liver function without rejection,but it cannot relieve portal hypertension.

Objective To describe the characteristics and risk factors for Mycobacterium tuberculosis (TB)infection in patients with systemic lupus erythematosus(SLE).Methods A retrospective analysis was per-formed. Results Among our sample of 784 hospitalized patients,42(5.4%)were diagnosed with TB infection. Seventeen were pulmonary TB,11 were pulmonary and extra-pulmonary TB and 14 were extra-pulmonary TB.hest X-rays showed Abnormal chest imaging was observed in 34 cases,among which,19 were multi-lobar involvements and 9 were single-lobe involvements. Logistic regression multivariate analysis indicated that anemia and the daily mean dose of glucocorticoid(GC)were associated with TB. Conclusions Manifestations of TB in SLE patients were atypical.Anemia and the daily mean dose of GC were associated with TB.

Objective:To evaluate the specific changes and importance of the proportions of the eyebrows and eyes after surgery by analyzing and measuring the changes of the values of the eyebrows and eyes in elderly patients with aponeurotic ptosis before.Methods:A total of 54 cases (108 eyes) of elderly patients with aponeurotic ptosis who were treated in our department from 2019.01 to 2020.12 were collected preoperatively and 6 months postoperatively, and they were set as the study group. At the same time, the data of 48 cases (96 eyes) of healthy people with good face were collected and set as the young control group, and the data of 50 cases (100 eyes) of elderly healthy people without ptosis were collected and set as the elderly control group. The corresponding objective data were analyzed, and the specific changes and proportional relationship of eyebrows and eyes after surgery were evaluated.Results:Compared with the preoperative data, the marginal reflex distance 1 (MRD1), the height of the palpebral fissure (HPF) in the study group increased at 6 months after the operation, and the distance between the eyebrow and eye at each site increased or shortened ( P<0.05). Six months after the operation, the brow height from medial canthus (MBH), the central brow and eye distance (brow height from upper eyelid margin on midpupillary level, CBH), and the lateral brow and eye distance (brow height from lateral, LBH) had been changed. The change rates of canthus compared with preoperatively were that (88.29±11.69)%, (85.04±14.96)%, and (93.61±13.56)%, respectively, among which CBH shortened most significantly, and the shortened distance was (3.76±2.43) mm. The MRD1 and HPF in the group increased significantly at 6 months after operation, which were significantly greater than those in the elderly control group ( P<0.05). CBH was significantly shortened ( P<0.05); compared with preoperative, the ratio of HPF/CBH, HPF/length of the palpebral fissure (LPF) in the study group increased at 6 months after operation, and the lateral canthus brow tail line [ratio of lateral canthus to lateral end of eyebrow (LLE)]/LPF decreased ( P<0.05); HPF/CBH in the study group was lower than that in the young control group at 6 months after operation, but greater than that in the elderly control group ( P<0.05). Monthly HPF/LPF was significantly higher than that of the elderly control group ( P<0.05), and the LLE/LPF of the study group was significantly higher than that of the young control group at 6 months after operation ( P<0.05); intraoperative levator muscle shortening (LMS) was negatively correlated with postoperative MBH, CBH and LBH ( P<0.05), among which LMS had the greatest correlation with CBH ( r=-0.587). Conclusions:After ptosis correction, the palpebral fissures are larger, the distance between the eyebrows and the eyes is shortened, and there is a certain proportional relationship. After surgery, the patient's eyebrow-eye ratio is better than that of the elderly in the same age group, and it is closer to the young people, and the intraoperative LMS has a correlation with the eyebrow-eye distance, which can be used as a factor to predict the shortened distance of the eyebrow-eye distance.

Objective:To investigate the effect of compound matrine injection on morphine tolerance in mice with lung cancer in situ and the expressions of multidrug resistance gene 1 (MDR1) and P-glycoprotein (P-gp).Methods:A mouse model of lung cancer in situ and morphine tolerance mode was established. The mice were injected with gradient concentration of compound matrine. The pain thresholds under different conditions were measured by thermal radiation tail-flick method. The mRNA level of MDR1 was tested by reverse transcription polymerase chain reaction (RT-PCR) and the protein level of P-gp was detected by western blot. The DNA binding activity of cyclophosphoadenosine response element binding protein (CREB) to the promoter of MDR1 gene was detected by electrophoretic mobility shift assay (EMSA).Results:The maximum analgesic percentage (MPE) of the mice in the morphine group was (85.21±6.53)% on the 8th day, and decreased to (38.45±5.52)% and (28.14±4.52)% on the 10th and 12th day, respectively, which indicated the morphine tolerance of mice with lung cancer in situ.The MPE of the mice in the group treated with morphine and compound matrine injection (300 mg/kg) was (79.34±6.50)% on the 8th day, and decreased to (62.16±5.53)% and (40.20±4.50)% on the 10th and 12th day, respectively.The results of RT-PCR assay showed that the relative expression levels of MDR1 mRNA in the brain tissues of mice in the morphine group, saline group, morphine combined with compound matrine injection (300 mg/kg) group and compound matrine injection (200 mg/kg) group were 2.33±0.79, 1.04±0.38, 1.37±0.38, and 1.43±0.53, respectively. There were statistically significant differences between the morphine group and the normal saline group, the morphine group and the morphine combined with compound matrine injection (300 mg/kg) group ( P<0.05). There was no significant difference between the normal saline group and the compound matrine injection (200 mg/kg) group ( P=0.05). The results of western blot showed that the relative expression levels of P-gp protein in the brain tissue of mice in the morphine group, saline group, and morphine combined with compound matrine injection (300 mg/kg) group were 1.86±0.40, 1.00±0.23, and 1.27±0.27, respectively. The expression of P-gp protein in the morphine group was significantly higher than those of the normal saline group and the morphine combined with compound matrine injection (300 mg/kg) group ( P<0.05). The DNA-binding activity of CREB in the saline group was (0.23±0.07) Pu, significantly lower than (0.89±0.23) Pu of morphine combined with naloxone group and (0.80±0.23) Pu of morphine group ( P<0.05). While the CREB DNA binding activity of morphine combined with compound matrine injection (300 mg/kg) group was (0.79±0.21) Pu, implicated that compound matrine had marginal effect on the DNA-binding activity of CREB ( P>0.05). Conclusion:Compound matrine injection can significantly improve morphine tolerance and drug resistance of lung cancer through inhibiting the upregulations of MDR1 and P-gp induced by morphine.

Objective:To analyze and compare the health education efforts of respiratory infectious diseases at home and abroad.Methods:The literature related to health education and popular science of respiratory infectious diseases included in the databases of China National Knowledge Infrastructure (CNKI) and Web of Science (WOS) from January 1, 2003 to December 31, 2023 was searched. A total of 4 686 articles were retrieved in CNKI, 1 540 articles unrelated to the theme were excluded, and 3 146 Chinese articles were obtained. In the WOS database, 7 724 articles were retrieved, 3 685 articles about the clinical mechanism of diseases, pharmacology, and other research topics were excluded, and 4 039 English articles were obtained. The information of annual publications, institutions, authors and keywords was analyzed by using CiteSpace visualization software, and the publication status, research hotspots and development trends of health education related to respiratory infectious diseases at home and abroad were analyzed.Results:Since 2003, the number of publications in health education on respiratory infectious diseases at home and abroad had shown a fluctuating growth trend, and in 2020, the field showed a sharp growth trend at home and abroad. There was no core author group in this field in China, and the network density of domestic authors was 0.006 5, and the network density of foreign authors was 0.009 6. The domestic institutions were mainly the Center for Disease Control and Prevention and medical institutions, including Guangzhou Chest Hospital (29 articles) and the Chinese Center for Disease Control and Prevention (10 articles); Foreign research institutions were mainly higher education institutions, including the University of London (91 articles) and Harvard University (67 articles). The network density of domestic was 0.001 3, and the network density of foreign publishing institutions was 0.026 3, the network density was greater than that of Chinese publishing institutions. The emergence of "COVID-19" "Avian influenza" "Knowledge, Attitude, Practice" and "mental health" in China had strong burst (burst intensity: 46.41, 12.12, 10.33, 8.5); "Coronavirus" "coverage" "Avian influenza" and "COVID-19 vaccine" in foreign countries had strong burst (burst intensity: 14.34, 11.06, 10.73, 10.02).Conclusions:At present, the health education of respiratory infectious diseases at home and abroad has received great attention. But the cooperation between domestic authors and research institutions is loose, and the close collaboration needs to be strengthened. There are differences in the research focus of health education on respiratory infectious diseases at home and abroad.

Objective:To observe the effect of a wrist brace on activities of spastic hemiplegic hand after stroke, based on Botulinum toxin type A (BTX-A) injection and electrical stimulation. Methods:From January, 2016 to December, 2018, 52 stroke patients with spastic hemiplegia on upper extremities accepted BTX-A injection, and electrical stimulation two days later, while group A (n = 26) wore a wrist brace during stimulation and group B (n = 26) did not. They were assessed with modified Ashworth Scale (MAS), Box and Block test (BBt) and Action Research Arm Test (ARAT) before treatment (T0), and two (T1), four (T2) and twelve 12 (T3) weeks after treatment. Results:The scores of MAS, BBt and ARAT improved after treatment in both groups (F_time > 118.32,P < 0.001), and improved more in group A than in group B in the scores of BBt and ARAT at each time point (F_group > 31.26,P < 0.001;F_interact = 10.65,P < 0.001). Conclusion:Based on the BTX-A injection and electrical stimulation, wearing a wrist brace would further improve the activities of hand for stroke patients.

Yigongsan is derived from Xiaoer Yaozheng Zhijue written by QIAN Yi in the Northern Song dynasty， which is the No. 3 formula in the Catalogue of Ancient Famous Classical Formulas（The Second Batch of Pediatrics） released by the National Administration of Traditional Chinese Medicine（TCM） in September 2022， and it can be developed as a class 3.1 new TCM drug. By referring to ancient medical books and modern literature， this study conducted herbal textual research on Yigongsan from five aspects， including historical evolution， origin and processing， dosage conversion， usage and preparation methods， and functional application， then formed the key information table of this formula， in order to provide reference for the development of reference samples and preparations of Yigongsan. Based on the results of the study， it is recommended that Panax ginseng should be removed the basal part of stem（rhizoma）， Poria cocos should be removed the peel， Citrus reticulata should be cut into shreds and Glycyrrhiza uralensis should be used. According to 4.13 g/Qian（钱）， 1 g/slice for ginger， 3 g for each jujube and 300 mL/Zhan（盏）， the doses of Ginseng Radix， Poria， Atractylodis Macrocephalae Rhizoma， Glycyrrhizae Radix et Rhizoma， Citri Reticulatae Pericarpium， Zingiberis Rhizoma Recens， Jujubae Fructus were 1.652， 1.652， 1.652， 1.652， 1.652， 5， 6 g， and the total amount was 19.26 g. The decocting method was to crush the medicinal materials into fine powder with 50-80 mesh， add 300 mL of water and decoct to 210 mL for each dose， then remove the dregs and take it warmly. This formula was recorded in ancient books as the main treatment for the cold-deficiency of spleen and stomach， and Qi stagnation in children with vomiting and diarrhea and lack of appetite. It has been flexibly applied by later generations of physicians， and is often used to treat anorexia， inflammation of the digestive tract， diarrhea and other diseases in children.
