Objective To explore the pathological changes of lung, expression of the relevant inflammatory factors and oxidative stress markers of Sprague-Dawley (SD) rats undergoing autologous orthotopic liver transplantation (AOLT). Methods Thirty SD rats were randomized into sham group and AOLT group. The pathological changes of lung, expression of the relevant inflammatory mediators and oxidative stress markers were detected . Results ( 1 ) Compared with the sham group , the pathological scores of lung tissue in AOLT group increased significantly and reached its peak at 8 h after surgery. Then the pathological scores decreased to the level of sham within 24 h to 48 h after surgery; (2)The relative expression of inflammatory mediators including TNF-α, IL-1β, IL-6 and IL-8 increased significantly and reached its peak at 8 h after surgery in AOLT group. Then decreased to the level of sham group within 24 h to 48 h after surgery; (3)The change trends of MDA and H2O2 were similar to inflammatory mediators.The relative SOD expression decreased significantly and touched the nadir at 8h after surgery and then increased. Conclusion The pathological changes of lung expression, the relevant inflammatory mediators and oxidative stress markers of rats underwent AOLT were consistent.

Objective To find the spectacular indexes in the diagnosis of acute rejection of renal transplantation with color Doppler ultrasonography. Methods Forty-two patients with renal rejection were confirmed with percutaneous needle biopsy and 115 patients with stable renal function were confirmed with following-up (>1 year) and clinical examination. The length, width, thickness, cortex thickness and resistive index (RI) of two groups were analyzed statistically. Then the specificity, sensitivity, misdiagnosis rate, false negative rate and consistency rate of renal volume, pyramid swelling, echo weakening, RI＜0.7, RI≥0.7 and RI≥0.8 were calculated. Results The length, width and thickness were statistically different in two groups (P＜0.05). In patients with renal rejection, the marginal blood vessels in renal cortex decreased, and the blood velocity reduced obviously in the diastolic phase and RI increased obviously (P＜0.05). The sensitivity of the above indexes were 55.30%, 55.20%, 42.10%, 57.90%, 31.60%, respectively, while the specificity were 71.30%, 87.10%, 25.70%, 74.20% and 98.20%, respectively. Conclusion Enlargement of renal volume, swelling of renal pyramids, echo weakening and RI increasing are specific indexes for diagnosis of acute rejection of renal transplantation.

Objective:To evaluate the effect of remote ischemic conditioning (RIC) on left ventricular (LV) myocardial perfusion, myocardial viability, LV remodeling, regional and global LV function serially following acute myocardial infarction (AMI) in Chinese mini-pigs.Methods:AMI was established in 12 Chinese mini-pigs (8 males, 4 females; age: 6-8 months) and they were randomly divided into RIC group ( n=6) and non-RIC group ( n=6). RIC was performed in pigs by blood pressure inflation on the lower limbs for 5 min period and 4 cycles immediately after surgery. A series of myocardial perfusion imaging and gated 18F-fluorodeoxyglucose (FDG) myocardial metabolism PET/CT imaging were performed longitudinally at the 1st, 14th, 28th and 56th days after AMI, and parameters including total perfusion defect (TPD), hibernating myocardium (HM), Scar, left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), summed motion score (SMS), summed thickening score (STS) and changes of these parameters were obtained. Independent-samples t test and Mann-Whitney U test were used to analyze data. Results:Nine Chinese mini-pigs survived after surgery and were performed imaging. Compared to non-RIC group ( n=4), HM at the 28th ((6.0±2.4)% vs (17.0±4.6)%; t=-4.158), TPD 14th-1st ((-11.8±5.4)% vs 9.0%(4.5%, 15.0%); z=2.449), TPD 28th-1st ((-15.3±3.9)% vs (12.0±3.0)%; t=-10.071), TPD 56th-1st ((-18.0±6.5)% vs 9.0%(4.5%, 12.0%); z=2.449), HM 28th-1st ((-10.5±6.9)% vs (8.3±2.1)%; t=-4.507), HM 56th-1st (-15.0%(-17.5%, -8.5%) vs 2.0%(0%, 7.0%); z=2.449) and LVEDV 14th-1st (-0.5(-2.5, 0) ml vs (13.0±4.4) ml; z=2.470) were reduced in RIC group ( n=5; all P<0.05). Conclusion:RIC can improve myocardial perfusion, delay LV remodeling in the acute stage and salvage hibernating myocardium in the subacute stage and chronic stage.

Background and objective Isoliquiritigenin(ISL)is an important pharmacological constituent of Glycyrrhiza glabra,which possesses a range of physiological and pharmacological activities,as well as significant antitumor ac-tivity,and can be used as a potential drug for targeted cancer therapy.LINC01503 is an oncogene,which has been closely asso-ciated with the malignant biological processes of many cancers.The aim of this study was to investigate the effects of ISL on the proliferation,apoptosis,invasion and migration oflung squamous carcinoma cells by regulating LINC01503.Methods Plasma was collected from lung squamous carcinoma patients and healthy individuals treated at Tangshan People's Hospital from Janu-ary 2021 to December 2022.The expression of LINC01503 in lung squamous carcinoma plasma,tissues and cells was detected by real-time quantitative fluorescence polymerase chain reaction(qRT-PCR).Lung squamous carcinoma cells were treated with different concentrations of ISL for 24 h,and LINC01503 expression was detected by qRT-PCR.The cells were treated in groups:si-NC group,si-LINC01503 group,DMSO(0.1％dimethyl sulfone)group,ISL group,pc DNA3.1(+)-NC group,pc DNA3.1(+)-LINC01503 group,ISL+pc DNA3.1(+)-NC group and ISL+pc DNA3.1(+)-LINC01503 groups.CCK-8 assay,clone formation assay,flow cytometry,Transwell assay and scratch assay were used to explore the effect of LINC01503 on the functional phenotype of lung squamous carcinoma cells.Results Fluorescence in situ hybridization results showed that the average fluorescence intensity of LINC01503 in tissue microarrays of lung squamous carcinoma patients was higher than that in paracancerous tissues(P＜0.05).The expression of LINC01503 in the plasma of patients with lung squamous carcinoma was higher than that in the plasma of healthy individuals(P＜0.05).Knockdown of LINC01503 inhibited the proliferation,invasion and migration of lung squamous carcinoma cells and promoted apoptosis(P＜0.05).ISL inhibited the proliferation,invasion,migration and promoted apoptosis of lung squamous carcinoma cells(P＜0.05).Overexpression of LINC01503 followed by intervention with ISL reversed the promotional effect of overexpression of LINC01503 on the proliferation,invasion and migration of lung squamous carcinoma cells as well as the inhibitory effect on apoptosis(P＜0.05).Conclusion LINC01503 was highly expressed in lung squamous carcinoma,and LINC01503 could promote the proliferation,invasion and migra-tion of lung squamous carcinoma cells and inhibit the apoptosis,ISL could inhibit the proliferation,invasion and migration of lung squamous carcinoma cells and promote apoptosis of lung squamous carcinoma cells by regulating the expression of LINC01503.

Objective:To investigate the efficacy of treatment of bromhidrosis by cutting off the apocrine glands under direct vision combined with micro electrocoagulation.Methods:From January 2017 to December 2017, 25 patients (50 sides) with axillary osmidrosis admitted to the First People’s Hospital of Yuhang District were treated with direct vision cutting and micro electrocoagulation to destroy the apocrine sweat glands, including 13 males and 12 females, aged 14-38 years, with an average age of 23 years. According to Young-Jin Park′s criteria for judging axillary osmidrosis, 21 cases were classified as grade 3 and 4 cases as grade 2. After tumescent anesthesia, the subcutaneous apocrine sweat glands, fat and hair follicles were cut off under direct vision. The subdermal vascular network was preserved, and the basement was destroyed one by one by using high-frequency electrocoagulation mode. After the operation, the evaluation was conducted according to the criteria for judging axillary osmidrosis formulated by Young-Jin Park.Results:The symptoms of axillary osmidrosis reached the standard of cure in 24 patients after operation, 1 case failed to reach the cure standard. Among the patients who reached the standard, there were 2 cases of necrosis of the skin flap and 1 case of hematoma after operation unilaterally, which were given actively dressing change, secondary debridement, suturing and hematoma removal, The follow-up period was 6 months to 1 year. During the follow-up period, 24 cases were cured, including 21 cases of grade one and 3 cases of grade zero. The treatment effect was stable.Conclusions:The treatment of axillary osmidrosis by cutting off the apocrine sweat glands under direct vision combined with micro electrocoagulation, exposing the apocrine sweat glands as much as possible, effectively removing the apocrine sweat glands and hair follicles, and reducing the recurrence rate of axillary osmidrosis. It is a simple, safe and effective treatment technology for axillary osmidrosis.

ObjectiveTo analyze the epidemiological characteristics of varicella in Minhang District， Shanghai from 2013 to 2022， and to evaluate the impact of adjusting the varicella vaccination program to a two-dose regimen and its inclusion in the Shanghai immunization program on the incidence of varicella. MethodsData on reported varicella cases from 2013 to 2022 in Minhang District were collected. Interrupted time series analysis and segmented regression models were used to analyze the changes in varicella incidence before and after the adjustment of varicella immunization strategies. ResultsFrom 2013 to 2022， the average annual incidence of varicella was 76.58/100 000， with the highest incidence in 2017 （119.21/100 000） and the lowest in 2022 （27.02/100 000）. The varicella incidence exhibited seasonal patterns with peaks occurring from March to June and October to January of the following year. Prior to the adjustment of varicella immunization strategies （2013‒2017）， the varicella incidence showed an upward trend （z=2.20， P=0.03）， while after the adjustment （2018‒2022）， a adownward trend was observed （2018‒2022） （z=-2.25， P=0.02）. Interrupted time series analysis showed that following the adjustment of varicella immunization strategies， an immediate change of -33.91/100 000 （t=-4.35， P<0.001） in varicella incidence was observed， and the incidence slope was -17.59/100 000 with a decline of 28.61/100 000 （t=-12.16， P<0.001） compared to before inclusion. ConclusionThe incidence of varicella in Minhang District， Shanghai from 2013 to 2022 exhibits distinct seasonal patterns. After adjusting the varicella vaccination program to a two-dose regimen and incorporating it into the immunization program， the second dose of varicella vaccine administration substantially increases. As a result， the rising trend of varicella incidence is effectively controlled， and the incidence level decreases significantly， showing a sustained downward trend.

ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.
