ABSTRACT
Objective:To investigate the safety and short-term efficacy of laparoscopic Nissen fundoplication in the treatment of refractory gastroesophageal reflux disease (rGERD).Methods:The clinical data of 61 patients underwent laparoscopic Nissen fundoplication from March 2018 to March 2022 in Jiangyin People′s Hospital were retrospectively analyzed. Among them, 14 patients had significant symptom relief after using proton pump inhibitor (PPI) before operation (group A), 30 patients had partial symptom relief after using PPI (group B), and 17 patients had persistent symptoms despite regular treatment with double-dose PPI for more than 8 weeks (group C). The surgical outcomes and recovery were compared among the three groups.Results:For the 61 patients, the surgical time was (117.46 ± 28.50) min, the intraoperative blood loss was 23.00 (8.00, 34.00) ml, and the postoperative hospital stay was 3.00 (2.00, 5.00) d. There were no statistically significant differences in surgical time, intraoperative blood loss, postoperative hospital stay, concurrent hiatal hernia repair and mesh placement among the three groups ( P>0.05). No short-term severe complications such as abdominal bleeding, abdominal infection and gastrointestinal perforation occurred in any group. There were no statistical differences in satisfaction score, subjective relief of overall postoperative symptoms, reflux symptoms, PPI usage, dysphagia, abdominal distention, diarrhea or constipation among the three groups ( P<0.05). No upper abdominal pain, recurrence and reoperation occurred in the three groups. Conclusions:Laparoscopic Nissen fundoplication has a definite therapeutic effect on rGERD, with significant anti reflux effects. There are no serious complications after surgery, and there are no recurrence or reoperation.
ABSTRACT
Objective To explore the clinical effect and safety of remimazolam combined with alfentanil in painless gastroenteroscopy in elderly patients.Methods 188 elderly patients who were scheduled to undergo painless gastroenteroscopy from October 2021 to February 2023 were selected and divided into group A,group B,group C,and group D by random number table method,with 47 cases in each group.The group A,group B and group C were used remimazolam 0.2,0.3 and 0.4 mg/kg,and alfentanil 3 μg/kg respectively,and the remimazolam 2.5 mg/time was added during the operation.The group D was used propofol 1.5 mg/kg and alfentanil 3 μg/kg,and a single dose of propofol 0.5 mg/kg was added during the operation.The hemodynamics at different time points[3 min before anesthesia administration(T0),immediately after endoscopy(T1),3 min after endoscopy(T2),at the end of examination(T3),at the time of awakening(T4)],anesthesia onset time,sedation success rate,gastrointestinal endoscopy time,awakening time,time to leave the observation room and intraoperative/postoperative complications were compared,and the test results of neurobehavioral cognitive state examination(NCSE)were compared at different times.Results The percutaneous arterial oxygen saturation(SpO2)at T1 and T2 time point were higher than group C and group D,and the differences were statistically significant(P<0.05).There was no statistically significant difference in the heart rate(HR)and mean arterial pressure(MAP)among group A,group B,group C and group D at each time point(P>0.05).There was no statistically significant difference in SpO2 between group A and group B at each time point(P>0.05).There was no statistically significant difference in the success rate of sedation,gastrointestinal endoscopy examination time and time of leaving the observation room among the four groups(P>0.05),but the onset time of anesthesia in group A was longer than that in group B,group C and group D,and the awakening time in group A and group B was shorter than that in group C and group D,and the differences were statistically significant(P<0.05).There was no statistically significant difference in awakening time between group A and group B(P>0.05).The incidence rate of bradycardia in group A and group B was lower than in group D,and the incidence rates of hypoxemia,respiratory depression,hypotension,and dizziness in group A were lower than those in group D,and the incidence rate of injection pain in group A,group B and group C was lower than that in group D,and the differences were statistically significant(P<0.05).After 10 minutes of complete wakefulness,there was no statistically significant difference in the passing rates of calculation ability and the memory tests between group A and group B(P>0.05),but the passing rates of calculation ability and memory test in group A were higher than those in group C and group D,and the differences were statistically significant(P<0.05).Conclusion During painless gastroenteroscopy in elderly patients,the sedative effect of using 0.3 mg/kg remimazolam combined with alfentanil is good,and it has stable hemodynamics,and the occurrence rate of complications such as bradycardia and espiratory depression is low,and the early postoperative cognitive function is recovered well.
ABSTRACT
AIM: To analyze the abnormal refractive status of infants and young children aged 6 to 48 months, and to provide basis for the correction of ametropia and the early prevention and treatment of amblyopia.METHODS: Infants and young children aged 6 to 48 months were examined for refraction by Spot vision screener for natural optometry. Clinical data of infants and young children with refractive abnormalities were collected, Ciliary muscle paralysis agent was used for retinoscopy and optometry, and the results were statistically analyzed.RESULTS: A total of 168 cases(336 eyes)with abnormal Spot refractive outcomes were collected, with a high proportion of hyperopia and astigmatism abnormalities, 38.4% and 28.6%, respectively, while the proportion of myopia was low(12.2%). There were 90 cases of anisometropia(≥1.00 D), among which 41 cases(45.6%)were astigmatic anisometropia, 33 cases(36.7%)were hyperopic anisometropia, and 16 cases(17.8%)were myopic anisometropia, accounting for the least proportion. A total of 109 infants and young children with Spot refractive abnormalities completed ciliary muscle paralysis retinal optometry. The analysis of the difference and correlation between Spot diopter and post ciliary muscle paralysis optometry results showed that the difference in astigmatism was 0.34±0.64 D(P<0.001), the difference in hyperopia was -2.10±1.27 D(P<0.001), and the difference in myopia was -0.43±0.91 D(P=0.023). Although there was a statistical difference between the two results, astigmatism, hyperopia, and myopia were highly positively correlated, respectively(r=0.694, 0.762, 0.909).CONCLUSION: The main refractive abnormalities in infants and young children aged 6 to 48 months are astigmatism, hyperopia, and anisometropia, with fewer abnormalities in myopia. For screening abnormalities, further ciliary muscle paralysis agent retinoscopy and optometry should be performed, and glasses correction should be given to effectively prevent refractive amblyopia in infants and young children.
ABSTRACT
ObjectiveTo investigate the induction of ferroptosis by polyphyllin Ⅱ （PPⅡ） in hepatocellular carcinoma HepG2 cells and its underlying mechanism. MethodThe effect of PPⅡ （0， 1.5， 3.0， 4.5， 6.0， 9.0， 18.0 mg·L-1） on the in vitro proliferation of HepG2 cells was assessed using the methyl thiazolyl tetrazolium （MTT） assay. Colony formation ability of HepG2 cells was evaluated through a colony formation assay. Cell migration ability was assessed via a scratch assay. Lactate dehydrogenase （LDH） content in HepG2 cells was measured using a kit. Reactive oxygen species （ROS） levels in HepG2 cells were observed using a fluorescence inverted microscope. Malondialdehyde （MDA）， glutathione （GSH）， and free Fe2+ content in HepG2 cells were detected using respective kits. The mitochondrial ultrastructure in HepG2 cells was observed by transmission electron microscopy. The expression of ferroptosis-related proteins p53， solute carrier family 7 member 11 （SLC7A11）， glutathione peroxidase 4 （GPX4）， long-chain acyl-CoA synthetase 4 （ACSL4）， and transferrin receptor 1 （TFR1） in HepG2 cells was detected using Western blot. ResultCompared with the control group， the PPⅡ treatment groups showed significantly decreased survival rate of HepG2 cells in a dose-dependent manner （P<0.01）， significantly reduced number of cell colonies （P<0.01）， significantly shortened scratch healing distance， inverse correlation of the migration distance with drug concentration （P<0.01）， significantly increased LDH leakage in cells （P<0.01）， significantly enhanced relative fluorescence intensity of intracellular ROS， and significantly increased accumulation of lipid peroxide MDA （P<0.01）， decreased intracellular GSH content with increasing drug concentration （P<0.01）， and significantly enhanced fluorescence intensity of FeRhoNox-1 in cells （P<0.01）. Moreover， cells exhibited vacuolation， and mitochondria showed significant shrinkage with reduced or even disappeared cristae. Compared with the results in the control group， the expression of p53， ACSL4， and TFR1 proteins significantly increased， while the expression of SLC7A11 and GPX4 proteins significantly decreased in the PPⅡ treatment groups （P<0.05）. ConclusionIn summary， PPⅡ induces ferroptosis in HepG2 cells by regulating the p53/SLC7A11/GPX4 signaling axis， promoting ACSL4 expression and Fe3+ uptake， leading to an imbalance in the antioxidant system.
ABSTRACT
BACKGROUND@#Lung cancer has been the leading cause of cancer-related deaths worldwide for many years. This study aimed to investigate the global patterns and trends of lung cancer.@*METHODS@#Lung cancer incidence and mortality were derived from the GLOBOCAN 2020 database. Continuous data from Cancer Incidence in Five Continents Time Trends were used to analyze the temporal trends from 2000 to 2012 using Joinpoint regression, and average annual percent changes were calculated. The association between the Human Development Index and lung cancer incidence and mortality was assessed by linear regression.@*RESULTS@#An estimated 2.2 million new lung cancer cases and 1.8 million lung cancer-related deaths occurred in 2020. The age-standardized incidence rate (ASIR) ranged from 36.8 per 100,000 in Demark to 5.9 per 100,000 in Mexico. The age-standardized mortality rate (ASMR) varied from 32.8 per 100,000 in Poland to 4.9 per 100,000 in Mexico. Both ASIR and ASMR were approximately twice higher in men than in women. The ASIR of lung cancer showed a downward trend in the United States of America (USA) between 2000 and 2012, and was more prominent in men. The age-specific incidence rates of lung cancer for ages of 50 to 59 years showed an upward trend in China for both men and women.@*CONCLUSIONS@#The burden of lung cancer is still unsatisfactory, especially in developing countries like China. Considering the effectiveness of tobacco control and screening in developed countries, such as the USA, there is a need to strengthen health education, accelerate the establishment of tobacco control policies and regulations, and improve early cancer screening awareness to reduce the future burden of lung cancer.

Urodynamic examination in the SCL + Cx43 group showed improvement in detrusor pressure, abdominal pressure and bladder pressure compared to the diabetic group(P < 0. 05) . In laser confocal experiments, the number of interstitial cells of Cajal (ICC) was reduced in the diabetic group, and the spindle structure and cell protrusions were obviously destroyed and appeared in a state of cell lysis. In the SCL and Cx43 groups, there was an improvement in the spindle structure and cell protrusion of ICC⁃like cells, and there was no significant change in the number of cells. In the SCL + Cx43 group, there was an increase in the number of ICC⁃like cells, a significant improvement in the spindle structure and cell protrusion, and the formation of ICC⁃dimers.@*Conclusion @#Transurethral co⁃infusion of SCL and Cx43 gene recombinant lentivirus can be successfully transfected in guinea pig DCP bladder, which can restore the number and structure of damaged ICC cells and form ICC dimer structure, improve the pressure of diabetic bladder forced urinary muscle, improve the weakness of urination, ventral pressure voiding and other characteristics. It provides a new direction for the treatment of DCP.
ABSTRACT
Targeted therapy characterized with high specificity and low toxicity, is an important treatment method for human epidermal growth factor receptor 2 (HER2)-positive breast cancer, which can prolong the disease-free survival and the overall survival time of HER2-positive early breast cancer patients, and prolong the progression-free survival and the overall survival time of HER2-positive advanced patients with breast cancer. However, targeted drugs blocked the normal signaling pathway outside the target organs, and some patients experienced treatment-related adverse reactions, resulting in dose reduction, treatment delay and interruption, or even life-threatening consequences. Cardiotoxicity is one of the potentially serious side effects of targeted-HER2 drugs. Currently the targeted drugs for treatment of HER2-positive breast cancer patients include macromolecular monoclonal antibody drugs such as trastuzumab and pertuzumab, antibody-drug conjugates such as T-DM1 and T-DXd, and small-molecule tyrosine kinase inhibitors. This paper reviews the cardiotoxicity of HER2 targeted drugs including antibody-drug conjugates monoclonal antibody drugs in targeted therapy for breast cancer in order to provide references for clinical treatment.

ABSTRACT
Objective To observe the tolerance and prognosis of chemotherapy in patients aged 80 year and over with lung cancer in China.Methods This retrospective study was performed on 30 patients aged 80 year and over with lung cancer who received chemotherapy at our hospital from 2012 to 2017.We collected basal clinical and laboratory data before chemotherapy,recorded the treatment regimens,side effects,and outcome of chemotherapy,and analyzed the overall survival of patients with stage Ⅳ lung cancer.Results The patients aged 80 90 years were mainly males (63.3％,19/30),and most of them had good performance status (PS) with PS 0-1 in 22 patients (73.3％) and activity of daily living (ADL) score ≥90 in 18 patients (60.0％).Patients were treated with a median of 4 chemotherapy courses,and half of them had adverse reactions of degree ⅢI or above.A total of 21 patients (70.0 ％) had myelosuppression and 3 (10.0 ％) had weakness,while clinical efficacy occurred in 17 (68.0％) patients.The median of overall survival was 8.5 months (95％CI:2.396-14.604) in 25 patients with stage IⅣ lung cancer.Conclusions Some patients with lung cancer aged 80 years and over can benefit from chemotherapy.The patients with better PS and ADL may be more suitable for chemotherapy.The adverse reactions of chemotherapy need to be closely monitored.
ABSTRACT
Objective To analyze the effect and possible mechanism of propofol on proliferation and inva-sion of lung cancer cells. Methods Lung cancer cells were cultured and divided into experimental control group, groupL,group M and group H.The optical density of cancer cell was detected by CCK-8.Meanwhile,the difference of the proliferation of cancer cells in each groupwas determined after down-regulation gene.The change of inhibition rate in four groups was analyzed by Transwell test. The expression of MMP-2 and mRNA in different groups were compared by Western blot and Q-PCR. Results the results of CCK-8 test showed the cancer cell viability in H group was lowest and the inhibition ability increasedafter silencing MMP-2 gene(P<0.05); the invasion inhibition rate of the lung cancer cells treated with propofol was higher(P<0.05), and invasion inhibition rate in each group also rise after silencing MMP-2; Western blot and Q-PCR show that the MMP-2 expression level in group Mand group H were lowest(P<0.05).Conclusion Propofol may inhibit the proliferation and invasion of lung cancer cells and its mechanism may be associated with down-regulation MMP-2,which is expected to inhibit the proliferation of lung cancer invasion.
ABSTRACT
Objective To explore the clinical effect of the high frequency transcranial magnetic stimulation in the treatment of Parkinson's non motor symptoms. Methods 80 patients with Parkinson's disease were randomly divided into observation group and control group by using random number table,40 cases in each group. The patients in the observation group received high-frequency repetitive transcranial magnetic stimulation treatment based on the conventional anti-Parkinson's disease drugs. The patients of the control group were treated with conventional anti-Parkinson's disease drugs. The therapeutic effect of the two groups was compared, The test results of the unified Parkinson's disease,Hamilton depression scale,scores of Pittsburgh sleep quality index before and after treatment were analyzed in the two groups . Results After treatment for 7 days and 1 month , the unified Parkinson ' s disease rating scale test results of the observation group were (29. 1 ± 7. 3) points,(29. 5 ± 6. 9) points,respectively,which were significantly lower than (38. 6 ± 9. 8) points before treatment,the difference was statistically significant( F=4. 881, P<0. 05). After treatment for 7 days,the Hamilton depression scale score of the observation group was (8. 33 ± 4.01)points,which was significantly lower than (13.55 ±8.27)points of the control group (t=2.356,P<0.05). After treatment for 1 month,the Hamilton depression scale score of the observation group was (8. 01 ± 3. 87)points, which was significantly lower than ( 12. 98 ± 8. 34 ) points of the control group , the difference was statistically significant(t=3. 018,P<0. 05). After treatment for 7 days,the Pittsburgh sleep quality index between the two groups had statistically significant difference [(19. 7 ± 2. 2) points in the observation group,(16. 1 ± 1. 1) points in the control group,t=2. 371,P<0. 05]. After treatment for 1 month,the Pittsburgh sleep quality index of the observation group was (26. 5 ± 1. 3) points,which was significantly higher than (17. 2 ± 1. 2) points of the control group ,the difference was statistically significant(t=3. 004,P<0. 05). Conclusion The high frequency transcranial magnetic stimulation in the treatment of non motor symptoms of Parkinson's disease can significantly improve the patients ' movement,speech,consciousness,emotion,sleep quality,and the effect is good.

ABSTRACT
Objective This study explored two methods of predicting the initial dose of heparin by heparin dose response curve(HDR)and in vitro heparin concentration progressive(HCP),and evaluated the predictive value of HCP for precise heparin dosage in patients undergoing cardiac surgery. Method Include 18-65 years old undergoing elective cardiac surgery patients,Before the start of the surgery internal jugular vein blood was taken in-to the HCP(2.5 mg/kg,3.0 mg/kg)test;The first injection of heparin 2 mg/kg via the internal jugular vein, then every 5 minutes each additional heparin 0.5 mg/kg to amount to 2.5 mg/kg,3.0 mg/kg,and measurement ACT and until ACT value≥480 s;According to HDR calculated per patient 2.5,3.0 mg/kg of ACT value;Respective-ly according to the HCP and HDR ACT values obtained by two methods with the actual measured by the correspond-ing value in the body. Results Comparing the ACT values measured by HDR and HCP with the corresponding ACT values in vivo:There are good similarity for heparinization ACT value between HCP and the actual body corresponding concentrations(r was 0.62 and 0.74,respectively),P<0.05;HDR results also have better similar-ity(r was 0.66 and 0.54,respectively),P < 0.05;However,HDR and HCP compared with the actual results in vivo found that in vitro HCP prediction results especially 3.0 mg/kg is more similar with the actual values.Conclu-sions HCP for predicting heparin dosage to meet extracorporeal circulation is more accurate.
