Glucagon-like peptide-2 (GLP-2) is a 33-amino acid peptide derived from the tissue-specific, post-translational processing of the proglucagon gene.GLP-2 is a newly discovered,specific for the intestine growth factor that affects gastrointestinal functions including epithelial growth of normal and developing intestinal preventing damage and facilitating intestinal repair in animal models and patients of intestinal disease. GLP-2 also inhibits gastrointestinal motility and gastric acid secretion, up-regulates intestinal blood flow and reduces food intake. The actions of GLP-2 are initiated by activation of the GLP-2 receptor (GLP-2R), a specific G-protein-linked membrane receptor. This review provides an overview of the physiological, pharmacological, and therapeutic actions of GLP-2 and GLP-2R signaling mechanism, with a focus on the most recent findings on the role of this peptide hormone in the normal and diseased gastrointestinal tract.

This study is to investigate the effects of sophoridine on NF-kappaB signaling pathway in kidney tissue of endotoxemia mice and the mechanism involved. BALB/c mice were challenged with lipopolysaccharide (LPS) caudal vein injection, then sophoridine was administered by intraperitoneal injection. Totally 50 mice were divided into 5 groups: control group, LPS model group, sophoridine treatment 12 mg x kg(-1) group, 6 mg x kg(-1) group and 3 mg x kg(-1) group. All animals were sacrificed at 6 hours after treatment. Kidney and blood samples were harvested. IKKbeta mRNA and TNF-alpha mRNA expression of renal tissue was measured by the reverse transcription polymerase chain reaction (RT-PCR), and phosphorylation IKKbeta protein (pIKKbeta) was detected by immunohistochemistry. NF-kappaB P65 protein expression and distribution of renal tissue were observed by Western blotting and immunofluorescence laser confocal microscopy. Serum TNF-alpha level was detected by radioimmunoassay. The results showed that the sophoridine significantly reduced the expression of IKKbeta mRNA and pIKKbeta protein, and inhibited the expression of NF-kappaB P65 protein and decreased the entry nuclear rate of NF-kappaB P65 in the renal tissue of endotoxemia mice. Thereby the renal TNF-alpha mRNA expression and serum TNF-alpha level were significantly reduced. These results suggest that sophoridine could inhibit inflammatory reaction induced by LPS through inhibiting activation of NF-kappaB signaling pathway.

Objective To evaluate the early effect and safety of artificial hip replacement for treating senile osteoporosis femoral neck fractures with different prostheses choice. Methods From January 2006 to April 2014, 387 patients with senile osteoporotic femoral neck fractures received artificial hip replacement. Their average age was 65 to 98 years old,with the average of 76.9 years old. Four prostheses were used in the artificial hip replacement, including 107 cases of biological total hip,94 cases of bone cement type total hip,104 cases of biotype artificial femoral head,and 82 cases bone cement artificial femoral head. We compared the operation time,bleeding amount, postoperative ambulation time,postoperative complication rate among the four prostheses. Results The biological hip replacement were superior to bone cement type in the operation time(50±10.3 min vs 61±11.5 min), bleeding amount(149±27.7 ml vs 205±47.3 ml)and postoperative complications(21% vs 38%),with statistical significant differences(P < 0.05). Other observations showed no statistically significance. Conclusion The biotype artificial joint replacement is applicable to the younger patients with thick bone cortex and long life expectancy,while the bone cement artificial joint replacement is appropriate for weak senile patients with thin bone cortex.

Objective To investigate the regularity and predictors of weight loss during concurrent chemo-radiotherapy for nasopharyngeal carcinoma patients. Methods A retrospective study was carried out on 82 patients with nasopharyngeal carcinoma ,with average age of 45 years ,who received concurrent chemoradiotherapy at the Affiliated Cancer Hospital of Guangzhou Medical University. Paired t-test was used to analyze the weight loss pattern during chemoradiotherapy. The Spearman′s rank correlation analysis was used to investigate the correlation between high weight loss(HWL)and the clinical factors. Results The paired t-test showed that the weight of the patients decreased continuously every week during chemoradiotherapy(P < 0.05),and the value dropped most significantly during the 4th week. Among these 82 patients,32 were determined as HWL(weight loss > 10%). Spearman′s rank correlation analysis showed that HWL was associated with older age,female,higher T and TNM stage,3D-CRT technology,the higher dose of radiotherapy in nasopharynx and in neck lymph node,and decreases of leukopenia and hemoglobin over degree Ⅱ(P<0.05). Conlousions Weight may decrease continuously every week during chemoradiotherapy for nasopharyngeal carcinoma patients. Age,gender,T stage,TNM stage,radio-therapy dose,and leukopenia and hemoglobin decreases may be predictors for weight loss degree during concurrent chemoradiotherapy for nasopharyngeal carcinoma patients.

Objective To evaluate Janus kinase (JAKs) and Suppressors of cytokine signaling(SOCSs) expression in myocardium after endurance training. Methods 30 male Sprague-Dawley rats undertook 10 weeks grade treadmill training program and were sacrificed at 0 and 24 h respectively after the last exercise. JAK1,JAK2,JAK3 and SOCS1 ,SOCS2,SOCS6 expression in the myocardium were determined by im munohistochemistry method. Results The percentage of JAK1 positive cell significantly increased immediately after last running and recovered to the sedentary level 24 hrs after exercise;The percentage of JAK2 positive cell significantly increased immediately after last running and continuously at a higher level 24 hrs after exercise (P<0.01;P<0.05); JAK.3 showed no significant change either immediately or 24 hrs after exercise (P>0.05). The percentage of SOCS1 and SOCS2 positive cell also significantly increased both immediately and 24 hrs after exercise (P<0.01 ;P<0.05). However, the percentage of SOCS6 positive cell showed no significant change either immediately or 24 hrs after exercise(P>0.05). Conclusion Endurance training could induce different responses of JAK1,JAK2 and JAK3. The increased expressions of JAK1 and JAK2 might indicate the changes of JAK/STAT signal pathway in regulating myocardial function. The increased expressions of SOCS1 and SOCS2 after endurance training might indicate the increased exertion in regulating JAK/STAT signal pathway in cardiac muscle.

Objective:
This study’s objective is to assess the efficacy and safety of Pulsed Magnetic Therapy System (PMTS) in improving insomnia disorder.
Methods:
Participants with insomnia disorder were randomly assigned to receive either PMTS or sham treatment for four weeks (n= 153; PMTS: 76, sham: 77). Primary outcomes are the Insomnia Severity Index (ISI) scores at week 0 (baseline), 1, 2, 3, 4 (treatment), and 5 (follow-up). Secondary outcomes are the Pittsburgh Sleep Quality Index at baseline and week 4, and weekly sleep diary-derived values for sleep latency, sleep efficiency, real sleep time, waking after sleep onset, and sleep duration.
Results:
The ISI scores of the PMTS group and the sham group were 7.13±0.50, 11.07±0.51 at week 4, respectively. There was a significant group×time interaction for ISI (F3.214, 485.271=24.25, p<0.001, ηp 2=0.138). Only the PMTS group experienced continuous improvement throughout the study; in contrast, the sham group only experienced a modest improvement after the first week of therapy. At the end of the treatment and one week after it, the response of the PMTS group were 69.7% (95% confidence interval [CI]: 58.6%–79.0%), 75.0% (95% CI: 64.1%–83.4%), respectively, which were higher than the response of the sham group (p<0.001). For each of the secondary outcomes, similar group×time interactions were discovered. The effects of the treatment persisted for at least a week.
Conclusion
PMTS is safe and effective in improving insomnia disorders.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

OBJECTIVEThis study was designed to investigate the plasma level of soluble ST2 (sST2) and related influencing factors, and establish its reference value in the healthy community-based population in Beijing area of China.
METHODSWe measured plasma sST2 level by enzyme-linked immunosorbent assay between March 2012 and August 2012 in 1 334 healthy subjects in communities, including 597 males and 737 females. Empiric and quantile regression methods were used to determine the reference range of plasma sST2. A multiple linear regression model was established to analyze the factors that might affect the level of plasma sST2.
RESULTSGender is the most important factor affecting the plasma level of sST2 in healthy people. Plasma level of sST2 is significantly higher in men than in women (P < 0.01). Within each age strata, i.e. < 45, 45-54, 55-64, ≥ 65 years old, the plasma levels of sST2 were significantly higher in men than age-matched female (all P < 0.01). Age, body mass index (BMI), systolic blood pressure, diastolic blood pressure, and smoking did not affect plasma sST2 level. Reference range of sST2 was 5.7-53.5 µg/L for men and 4.4-42.4 µg/L for women (95% nonparametric reference interval). The one-side upper 95th percentile value of sST2 to discriminate the cardiovascular disease from healthy state was 47.2 µg/L for men and 37.2 µg/L for women.
CONCLUSIONSThis study established the normal reference range of plasma sST2 in healthy community-based population. The major influencing factor of sST2 level in healthy population is gender.
