Objective To extract ?-glucosidase inhibitors from Potentilla anserina L. Methods Water-decocting method and water-decocting ethanol-precipitation were applied to obtain water extract,sodden ointment and polysaccharides of Potentilla anserina L. The colorimetry of pNPG was used for the determination of the activity of alpha-glucosidase pure enzyme and alpha-glucosidase from isolated small intestines of natural ICR mice. Results The extracts of Potentilla anserina L. had obvious inhibitory effect on the pure enzyme of ?-glucosidase. The water extract and sodden ointment also had inhibitory effect on ?-glucosidase from isolated small intestine in natural ICR mice,the effect being in a dose-dependant manner. Conclusion The extracts of Potentilla anserina L. have the inhibitor-like effect on ?-glucosidase,and the active position is probably in the sodden ointment.

Objective: To observe the effect of Shenfu Injection on carcinemia and study its mechanism.Methods: Mice C57 Lewis lung cancer model were established.The changes of physiological conditions(body weight,food and water intake),the serum levels of tumor necrosis factor-?(TNF-?),interleukin-6(IL-6) and interleukin-1(IL-1) were observed in the experiment.Results: Shenfu Injection can signifi cantly increase water and food intake of carcinemia mice,and inhibited the loss of body weigh(P

OBJECTIVETo investigate the compositions of Th1/Th2/Th3 cells in chronic hepatitis B virus (HBV)-infected individuals by determining the expression of interleukin-4 (IL-4), inetrferon-gamma (IFN-gamma), and transform growth factor-beta (TGF-beta) in single CD4(+) T cells isolated from peripheral blood mononuclear cells (PBMCs) and the role of polarized Th cell populations in chronic HBV-infection was discussed.

METHODSPBMCs from chronically infected HBV individuals were isolated, stimulated by PMA/Ionomycin/Monensin, and IL-4, IFN-gamma and TGF-beta production by CD4(+) T cells was determined by using fluorescence activated cell sorter (FACS) analysis.

RESULTSThe percentage of IFN-gamma-producing T cells, IL-4-producing T cells and TGF-beta-producing T cells ranged from 2.3% - 18.6%, 1.1% - 8.7% and 0.7% - 7.1% respectively in CD4(+) T cells from non-infected individuals. Most of CD4(+) T cells from PBMCs in chronically infected HBV individuals were Th0 cells. The proportion of Th1 cells increased significantly with hepatic inflammatory activity, and in the active period of chronic hepatitis B infection were higher than those in the non-active period (P < 0.05). Th2 cell percentage in CD4(+) T cells from HBV-infected individuals did not differ significantly (P > 0.05), but were higher than that from controls (P < 0.05). Th3 cell percentage in CD4(+) T cells from asymptomatic carrier (AsC) group was higher than that in the chronic hepatitis B (CHB) and control groups (P < 0.05).

CONCLUSIONSTh1 phenotype cytokines were positively correlated with hepatic inflammatory activity in chronic hepatitis B and Th2 cells may be associated with the persistence of HBV infection. Th3 cells cooperating with Th2 cells can negatively regulate immune responses and may be associated with the immune tolerant state of chronic HBV infection.

Objective To compare the clinical efficacy of extra vascular occlusion of low abdominal aorta and low abdominal aorta balloon occlusion in the treatment of placenta previa with placenta previa.Methods From January 2014 to July 2017,68 implantable placenta previa patients were divided into two groups,elective cesarean section of extra vascular occlusion of low abdominal aorta in 34 cases(group A)and cesarean section on the lower abdominal aorta balloon occlusion in 34 cases(group B),and observation of pregnant women was compared between surgery of two groups. Results Operation time,complications of vascular injury and thrombosis,fetal radiation exposure in group A were significantly lower than that of group B(P<0.05);two groups of patients with sensory dysfunction incidence,cesarean operation time,intraoperative blood loss,blood transfusion rate,the uterus resection rate,hospitalization time had no statistically significant difference postoperatively(P > 0.05). Conclusion Two kinds of operation can safely and effectively reduce the bleeding during the treatment of placenta previa. While group A surgery operation time is short,without intraoperative and postoperative bleeding of the puncture site,without pelvic and lower extremity arterial thrombosis,without X-ray exposure,more safety of the womb and can be popularized in clinic.

Objective To explore the quality of life ( QoL ) and muscle strength in patients with pseudohypoparathyroidism ( PHP ) under regular treatment. Methods Twenty-three patients with PHP regularly followed at Peking Union Medical College Hospital from June 2017 to June 2018 were included. Age- and gender-matched 23 patients with nonsurgical hypoparathyroidism ( nHPT) and 23 healthy controls were also included. Short Form 36 Health Survey questionnaire version 2 ( SF36v2) were used to evaluate the QoL. Grip strength and repeated chair stand ( RCS) were used to assess muscle strength for upper and lower limbs respectively. Results Except for physical functioning, patients of PHP group had reduced scores in all other subdomains of SF36v2 compared to healthy controls ( P<0.05) . Comparing to nHPT patients, PHP patients had a higher score in social functioning, while no difference was found in other subdomains of SF36v2. Grip strength and RCS tests were similar in PHP patients and healthy controls. Conclusions Comparing to healthy controls, patients with PHP still had impaired QoL despite regular management, no significant difference of upper and lower limb muscle strength was found between PHP group and healthy controls.

Objective To investigate the effect of blood flow restriction combined with low-intensity plyometric jump training(LI-PJT+BFR)on lower limb dynamic postural control of functional ankle instability(FAI)in college students. Methods From March to May,2023,40 FAI college students were recruited from Xi'an Physical Education University,and randomly divided into high-intensity plyometric jump training(HI-PJT,n = 14)group,low-intensity plyomet-ric jump training(LI-PJT,n = 13)group and LI-PJT+BFR group(n = 13).All the groups finished the six-week corresponding training.The maximum voluntary isometric contraction(MVIC)of tibialis anterior,peroneus lon-gus,lateral head of gastrocnemius,gluteus maximus,vastus lateralis,biceps femoris and semitendinosus were measured,and the root mean square(RMS)of electromyography of these muscles was measured during the sin-gle-leg landing(SLL),using wireless surface electromyography before and after intervention.Moreover,they were assessed with Y-balance test and Cumberland Ankle Instability Tool(CAIT). Results MVIC and RMS of the target muscles improved after intervention in all the groups(t>2.218,P<0.05),except MVIC and RMS of peroneus longus,gluteus maximus,biceps femoris and semitendinosus in LI-PJT group,and RMS of peroneus longus in LI-PJT+BFR group;and MVIC and RMS of the target muscles were the least in LI-PJT group(F>3.262,P<0.05),except those of peroneus longus.The extension scores of Y-balance test and the total score improved after intervention(t>2.485,P<0.05),and they were the least in LI-PJT group(F>5.042,P<0.05).The CAIT score improved after intervention(t>5.227,P<0.001),and it was the least in LI-PJT group(F = 4.640,P<0.05). Conclusion LI-PJT+BFR could improve lower limb dynamic postural control of FAI college students,which is similar to HI-PJT.

Objective: To investigate the association of GNA11 gene polymorphisms with the risk of adult-onset non-surgical hypoparathyroidism (Ns-HypoPT). Methods: Genotyping of GNA11 single nucleotide polymorphisms (SNPs) (rs28685098, rs4806907, rs11084997 and rs78003011) was carried out in 203 patients and 209 healthy participants by sequenom MassArray iPLEX System. These SNPs are located in promoter and 3′untranslated region (3′UTR) of GNA11 gene, respectively. Results: Allele and genotype frequencies of rs11084997 in patients were significantly different from those of controls (genotype GG:60.5% vs. 49.8%, GC: 35.5% vs. 41.6%, CC: 4.0% vs. 8.6%, P=0.038; G allele 78.3% vs. 70.6%, C allele 21.7% vs. 29.4%, P=0.012), and the C allele of rs11084997 carriers had a lower risk to develops Ns-HypoPT in additive and dominant genetic models [OR=0.382 (0.160-0.915), 0.647 (0.437-0.957)]. CC-Haplotype formed by the minor alleles of rs4806907 and rs11084997 was associated with a decreased risk of Ns-HypoPT in additive, dominant and recessive genetic model [OR=0.317 (0.126-0.801), 0.640 (0.430-0.952), 0.367 (0.148-0.912)]. Conclusion The minor allele C of rs11084997 in GNA11 gene promoter was associated with decreased risk of Ns-HypoPT in Chinese population.

Objective:To analyze the clinical characteristics and molecular mechanisms of 5 cases of hypoparathyroidism caused by GATA3 gene mutation.Methods:A total of 5 childhood-onset hypoparathyroidism patients with GATA3 mutation were identified from 198 hypoparathyroidism (aged ≤18 years) from 1975 to 2021 in Peking Union Medical College Hospital. Clinical data and biochemical indices of the 5 patients were collected and analyzed retrospectively. Genetic screening was conducted by targeted next-generation sequencing (T-NGS), and bioinformatics analysis was performed to analyze the underline mechanisms.Results:The medium onset age of hypoparathyroidism of the 5 patients was 0.5 (0.1, 1.3) years old, and the time duration from onset to confirmed diagnosis of hypoparathyroidism and hypoparathyroidism- deafness-renal dysplasia syndrome was (7.0±5.2) years and (15.0±5.4) years, respectively. The clinical manifestations included carpopedal spasm accompanied by seizures (5 cases), basal ganglia calcification (5 cases), cataract (1 case), deafness (4 cases), and renal malformations or absence (2 cases). The blood calcium and blood parathormone(PTH) before treatment was (1.65±0.31) mmol/L and (4.64±2.63) ng/L, respectively. The 5 patients carried different heterozygous mutations in GATA3 gene, which caused nonsense mutations, frameshift mutations and splice site mutations, respectively. All the GATA3 gene mutations of the 5 patients are classified as pathogenic or likely pathogenic by the Clin Var database and American College of Medical Genetics and Genomics(ACMG).Conclusions:Attention should be paid to genetic diseases in patients with childhood-onset hypoparathyroidism. The possibility of hypoparathyroidism-deafness-renal dysplasia syndrome should be considered in hypoparathyroidism patients with hearing loss or renal dysplasia. GATA3 gene screening is highly recommended for the confirmation of the diagnosis.

OBJECTIVE: To compare the effects of medical ozone oil and urea ointment for prevention and treatment of hand-foot skin reaction (HFSR) caused by sorafenib in patients with hepatocellular carcinoma (HCC). METHODS: A total of 99 patients diagnosed with advanced HCC according to National Comprehensive Cancer Network (NCCN) who were scheduled to receive sorafenib treatment for the first time were enrolled in this study between April, 2018 and January, 2020. The patients were randomized into medical ozone oil group ( RESULTS: Eight patients were excluded for poor compliance or protocol violations, leaving a total of 91 patients for analysis, including 44 in medical ozone oil group and 47 in urea ointment group. Sixteen (36.4%) of patients in ozone oil group developed HFSR, a rate significantly lower than that in urea ointment group (57.4%; CONCLUSIONS Medical ozone oil can significantly reduce the incidence and severity of HFSR to improve the quality of life of HCC patients receiving sorafenib treatment.
