Objective:To investigate the protective effects of Ghrelin on LPS-induced apoptosis of human alveolar epithelial A549 cells,along with the possible molecular mechanisms.Methods: CCK-8 assay was used to examine the cell viability of A549 treated by LPS.Apoptosis of A549 cells was measured by TUNEL.NO(Nitric oxide)production was detected by NO-specific fluorescent probe 3-Amino,4-aminomethyl-2′,7′-difluoresceindiacetate(DAF-FM DA).Western blot was also performed to examine the expressions of iNOS(inducible nitric oxide synthase),AKT,ERK,p-AKT,p-ERK and apoptotic proteins,such as Bcl-2,Bax,and cleaved caspase-3.Results: LPS exposure impaired cell viability and increased apoptosis of A549 cells significantly in concentration-and time-dependent manners accompanied with increased Bax and cleaved caspase-3 production,coupled with decreased Bcl-2 levels.Meanwhile,LPS promoted iNOS expression and the production of NO.Ghrelin pretreatment ameliorated LPS-caused alterations in the ratio of Bax/Bcl-2 and cleaved caspase-3 expression.TUNEL analysis showed that Ghrelin could decrease the apoptosis induced by LPS in A549(P<0.05).Simultaneously,LPS remarkably decreased the expression of p-AKT and p-ERK in A549 cells,which was abrogated by Ghrelin pretreatment.However,Ghrelin had no significant effect on NO production induced by LPS.Conclusion: Ghrelin reduces LPS-induced apoptosis of human alveolar epithelial cells partly through activating the AKT and ERK pathway,but the level of iNOS derived NO could not be reduced.

Objective To evaluate the effectiveness of melformin sustained release tablets in treatment of patients with abnormal glucose tolerance. Methods 78 cases with abnormal glucose tolerances were selected and divided into two groups. Patients in treatment group took melformin sustained release tablets, while patients in control group took normal therapy. The impaired glucose tolerance (IGT) and body mass index (BMI) were observed and compared. Results The blood glucose level of OGTT 2 h in treatment group was (7.61±1.04)mmol/L, while it was only (9.96±1.08) mmol/L in control group. The BMI of treatment group was 23.71±3.41, while it was 29.53±3.72 in control group. The glycosylated hemoglobin was (5.79±0.41)%, while it was (6.23±0.52)%in control group. The fasting blood glucose in treatment group was (5.34±0.39)mmol/L and in control group was (8.16±0.48)mmol/L. The differences of those indicators between two groups were signiifcant. Conclusion Melformin gains excellent clinical effects in treating patients with abnormal glucose tolerance. It can adjust blood glucose, improve glucose tolerance, and decrease blood glucose level of OGTT 2 h and BMI effectively.

Objective:To investigate the current situation of kinesiophobia in patients after heart valve replacement surgery and to analyze its influencing factors, and to provide reference for the intervention research of patients with cardiophobia after cardiac valve replacement.Methods:Using cross-sectional survey method and convenient sampling method, 109 patients who underwent cardiac valve replacement surgery in department of cardiothoracic and vascular surgery of Guangxi Zhuang Autonomous Region People′s Hospital from March 2021 to January 2022 were selected as the study subjects. The patients were surveyed with the general questionnaire, Tampa Scale of Kinesiophobia and Visual Analogue Scale.Results:After heart valve replacement, the score of Tampa Scale of Kinesiophobia was (46.90 ± 9.30) points. The score of Visual Analogue Scale was (5.83 ± 1.01) points. The score of Tampa Scale of Kinesiophobia was positively correlated with the score of Visual Analogue Scale ( r=0.46, P<0.01). Multiple linear regression analysis showed that patient′s age, cardiac function level, left ventricular ejection fraction, pain were the main influencing factors of Kinesiophobia ( t values were -2.37-4.34, all P<0.05). Conclusions:Medical staff should understand and accurately assess the status of patient′s kinesiophobia after heart valve replacement surgery, identify high-risk groups of kinesiophobia, and take targeted nursing measures to effectively alleviate postoperative pain, thereby reducing the incidence of kinesiophobia in patients, helping patients to carry out early functional exercise, and prorroting physical recovery.

Objective:To explore the establishment and validation of a risk model for postoperative olfactory impairment in pa-tients with chronic sinusitis with nasal polyps(CRSwNP)based on immunoinflammatory indexes.Methods:Retrospective analysis of 100 patients who attended CRSwNP in the Second Affiliated Hospital of Hainan Medical College from October 2020 to October 2022 all underwent nasal endoscopic surgery and were divided into no olfactory impairment group(44 cases)and olfactory impairment group(56 cases)according to the results of postoperative olfactory test,baseline data and routine examination indexes of the two groups were compared and analyzed,independent risk variables affecting olfactory impairment in CRSwNP patients were analyzed by Logistic multifactorial regression,and columnar graph prediction model was constructed and validated.Results:There were statistical-ly significant differences in staging,lesion site,Lund-Mackay score,anterior olfactory fissure score,posterior olfactory fissure score,percentage of serum eosinophils,olfactory marker protein-positive cell count in the upper turbinate mucosa,and urea nitrogen be-tween the two groups of CRSwNP patients(P<0.05).IL-5,human eosinophil cationic protein(ECP)/peroxidase(MPO),tissue inhib-itor of metalloproteinases 1(TIMP1),chemokine 2(CCL2),chemokine 3(CCL3),chemokine 4(CCL4),total immunoglobulin E(IgE)of tissue specimens,and total IgE of serum specimens in the olfactory impairment group were higher than those in the group without olfactory impairment,the differences were statistically significant(P<0.05).The multifactorial logistic results were that stag-ing,lesion site,Lund-Mackay score,anterior olfactory fissure score,posterior olfactory fissure score,IL-5,ECP/MPO,CCL4,and total IgE of tissue specimens were all independent risk factors affecting olfactory impairment in patients with CRSwNP;while olfactory marker protein-positive cell count in the upper turbinate mucosa was an independent protective factor for olfactory impairment in pa-tients with CRSwNP.The results were validated by establishing a line graph model.The validation results of building the column line graph model suggested that the C-index of the training and validation sets were 0.858 and 0.825,respectively,and the area under the characteristic curve(AUC)of the subject patients were 0.853 and 0.815,respectively.Conclusion:A model to explore the risk of postoperative olfactory impairment in CRSwNP patients based on immunoinflammatory indexes has been established,the model with high predictive performance to help guide clinical decision making.

OBJECTIVE: To explore the genetic basis and pregnancy outcome of fetuses with urinary system anomalies. METHODS: Ultrasonographic features, genetic testing and pregnancy outcomes of 337 fetuses with urinary system anomalies identified by prenatal ultrasonograhy were collected for analysis. RESULTS: Ultrasonographic features of the fetuses were mainly characterized by hydronephrosis or hydronephrosis, polycystic kidney disease, and renal dysplasia. Thirty four fetuses (10.1%) were found to harbor a genetic defect, including 14 numerical chromosomal disorders, 10 structural chromosomal aberrations, and 10 pathogenic copy number variations (CNVs). In 31 cases, the parents elected induced labor. For the 303 fetuses with negative findings, 142 were born by spontaneous delivery or Caesarean section, 48 cases underwent induced labor, 1 case had miscarriage, and the remaining 112 cases had unknown or missed pregnancy outcomes. CONCLUSION Hydronephrosis or hydronephrosis, polycystic kidney disease, and renal dysplasia are the most common findings among fetuses with urinary system anomalies. Approximately 10.1% of such fetuses are positive by genetic testing.

Objective To analyze the expressions of lymphocytes in the peripheral blood and serum cytokines in the children with secretory otitis media (SOM) and the effects of glucocorticoids interventions.Methods Totally 90 SOM children were selected as case group,and 30 healthy children were selected as control group.The case group was randomly divided into group A (simple oral antibiotic treatment),group B (oral antibiotics combined with local glucocorticoid treatment) and group C (oral antibiotics combined with systemic glucocorticoid treatment),30 cases in each group.The CD4 + T lymphocytes percentage,CD8 + T lymphocytes percentage,the ratio of CD4 +/CD8 + T lymphocytes in peripheral blood and the serum interleukin-2 (IL-2),interferon gamma (IFN-γ),tumor necrosis factor alpha (TNF-α),interleukin-6 (IL-6),interleukin-10 (IL-10) levels were detected and compared between case group and control group.The air conduction auditory thresholds under different frequency of the patients in group A,group B and group C were examined and compared.Results The CD4 + T lymphocytes percentage,the ratio of CD4 +/CD8 + T lymphocytes in peripheral blood and the serum IL-2,IFN-γ,TNF-α,IL-6,IL-10 levels of the patients in the case group were significantly higher than those in the control group (P ＜ 0.0 5).After the treatment,the above indicators of the children in group A,group B and group C decreased,and there were significant differences before and after the treatment between two groups (P ＜ 0.05).The air conduction auditory thresholds under different frequency of the patients in group B or group C were significantly lower than those in group A (P ＜ 0.05),while there were no significant differences in the air conduction auditory thresholds under different frequency between the children in group B and group C (P ＞ 0.05).Conclusion The patients with SOM show imbalanced cell immune function and cytokines expressions in the peripheral blood.The combination of glucocorticoids therapy and routine antibiotic therapy can effectively improve the immune function and the therapeutic effects.

Objective:To explore the clinical effect of a modified single-trunk arterialised venous flap in reconstruction of soft tissue defect in hand and foot.Methods:From January 2019 to June 2022, 25 patients with soft tissue defect in hand and foot were treated in the Department of Hand and Foot Plastic Surgery of Lecong Hospital of Shunde in Foshan. The soft tissue defects were reconstructed with a venous flap, of which a single trunk of vein was ligated and then a blood flux of the flap was re-established via a modified single vein trunk. One patient had soft tissue defect in dorsal foot and toes, 3 patients had defects in dorsal hand, 3 patients had defects in 2 digits and 18 patients had defects in single-digit. The sizes of defects were 2.0 cm×1.0 cm-10.0 cm×4.5 cm. The sizes of flaps were 2.0 cm×1.0 cm-12.0 cm×5.5 cm. Donor sites of the 19 cases were directly sutured and 6 were covered by skin grafts. The postoperative follow-ups were conducted at outpatient clinics and via telephone reviews to observe the survival of flaps. Functional recovery of 23 cases whose soft tissue defects in hand were evaluated according to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association. The sensory recovery of flaps was evaluated according to the comprehensive flap scale.Results:All 25 single-trunk venous flaps survived successfully. There were small number of blisters on 5 flaps, due to tissue oedema. One patient lost in follow-up. The other 24 patients had 2-18 months of follow-up. The appearance of flaps was soft and thin, with wear-resistant. According to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, the function recovery were excellent in 12 cases, good in 9 cases and poor in 2 cases. Sensations of the flaps were 90-99 point with an average of 97 point according to the comprehensive flap scale, of which 22 flaps were in excellent and 2 in good.Conclusion:The method of ligation of single vein-trunk to make a arterialised venous flap is a simple surgical procedure. There are many selections of donor site with minimum damage. It is an effective method and with satisfactory outcomes.
