ABSTRACT
Objective To investigate the effects of dynamic lung compliance(Cdyn)-guided indi-vidual positive end-expiratory pressure(PEEP)titration on pulmonary function in elderly patients undergoing laparoscopic colorectal cancer surgery.Methods Sixty-eight elderly patients were selected for laparoscopic radical resection of colorectal cancer,37 males and 31 females,aged 65-79 years,BMI<30 kg/m2,ASA physical status Ⅱ or Ⅲ.The patients were divided into two groups using the random number table method:individualized PEEP group(group P)and control group(group C),34 patients in each group.In group P,the patients received recruitment maneuvers and PEEP titration test at immediately after intubation,immediately after establishing pneumoperitoneum-Trendelenburg position and immediately after pneumoperitoneum.The patients in group C received PEEP 5 cmH2 O during procedure.The three best titra-tion PEEP and the actual tidal volume(VT)in group P were also recorded.PaO2,PaCO2,PETCO2 10 mi-nutes after the tracheal intubation(T1),10 minutes(T2)and 1 hour(T3)after establishing pneumoperito-neum-Trendelenburg position,at the end of the surgery but before extubation(T4)were recorded,and the oxygenation index(OI),physiological dead space to tidal volume(Vd/VT),alveolar arterial oxygen differ-ence(A-aDO2),driving pressure,and Cdyn were calculated.Concentrations of interleukin-8(IL-8),tumor necrosis factor-α(TNF-α),Clara cell secretoyr protein(CC16)and lung alveolar surface active sub-stances-D(SP-D)in the serum samples were determined by ELISA before anesthesia induction(T0)and 10 minutes after extubation(T5).Postoperative pulmonary complications(PPCs)were also recordrd.Results The individualized PEEP of Cdyn?guided PEEP titration was 4 cmH2O. Compared with group C, the PaO2 and OI in group C were significantly increased at T4, the Cdyn was significantly increased at T1,T3, and T4, the driving pressure was significantly decreased at T1 -T4, the serum concentration of CC16 was significantly decreased at T5 ( P < 0. 05). There were no significant differences in PaCO2, PET CO2,A?aDO2, and Vd/ VT between the two groups. There was no severe PPCs in the two groups. Conclusion Pressure?controlled ventilation modes combined with Cdyn?guide PEEP titration can increase the Cdyn, reduce thedriving pressure, and improve OI at the end of the operation, reduce the concentrations of CC16 at postop?eration, improve pulmonary function in elderly patients undergoing laparoscopic colorectal cancer surgery.
ABSTRACT
Objective To investigate whether the pituitary tumor transformation gene 1(PTTG 1)plays a role in colitis by regulating intestinal epithelial cells pyroptosis.Methods Ten PTTG 1 wild-type(WT)mice and Ten PTTG 1 knockout(KO)mice were randomly divided into 4 groups of 5 each,respectively PTTG1 WT control and experimental group,PTTG1 KO control and experimental group.The mice in the experimental group were given 3%dextran sodium sulfate(DSS)for 6 days to induce acute colitis,and the control group was given sterile double distilled water(ddH2O).The disease activity index of the respective group of mice was observed and recorded.Mouse colonic tissue were collected,and the expression levels of NLRP3,ASC,and GSDMD were determined by immuno-histochemistry and western blot.In HCoEpiC,PTTG1 expression was knocked down using shRNA,and the cells were subsequently treated with TNF-α to induce inflammation.Then,the expression of GSDMD was detected.Results The expression of PTTG1 was decreased in colonic mucosal tissue in mice with acute colitis(P<0.01).Compared with WT mice,the colitis was significantly aggravated in PTTG1 KO mice after 3%DSS treatment.The expression of pyroptosis-related proteins was significantly up-regulated in the colon mucosal tissues of PTTG1 KO experimental mice(P<0.05).After knocking down the expression of PTTG1 in HCoEpiC and TNF-α treatment,the expression levels of GSDMD were significantly up-regulated(P<0.05).Conclusion PTTG1 reduced pyroptosis in intestinal epithelial cells(IECs),while PTTG1 loss can enhance IEC pyroptosis,aggravating colonic inflammation.
ABSTRACT
ABSTRACT Objective: To clarify the association between smoking and stricture recurrence after urethroplasty. Materials and Methods: Pubmed, Web of Science, Embase, and Cochrane databases were searched with keywords: "urethroplasty," "buccal mucosa graft urethroplasty," "oral mucosa graft urethroplasty," "excision and primary anastomosis urethroplasty," "urethral stricture recurrence" until July 1, 2022. Inclusion and exclusion criteria were based on PICOS principles. The quality of included studies was assessed by Newcastle-Ottawa Scale (N.O.S.) system. Hazard ratio (H.R.), odds ratio (OR), and relative risk (RR) with 95% confidence interval (CI) were extracted or re-calculated from included studies. Meta-analysis was performed with Stata 15.0 based on univariate and multivariate data separately. Sensitivity analysis was performed to test the stability of the meta-analysis. I2 was calculated to evaluate heterogeneity. Publication biases were assessed by Egger's and Begg's tests. Funnel plots of univariate analysis and multivariate analysis were also offered. Results: Twenty one studies with 6791 patients were involved in this meta-analysis. The analysis results of the two stages were consistent. In the univariate meta-analysis stage, 18 studies with 5811 patients were pooled, and the result indicated that smoking might promote stricture recurrence (RR=1.32, P=0.001). Based on the adjusted estimate, 11 studies with 3176 patients were pooled in the multivariate meta-analysis stage, and the result indicated that smoking might promote stricture recurrence (RR=1.35, P=0.049). There was no significant heterogeneity in both the univariate and multivariate stages. Conclusion: Our study demonstrates that smoking may prompt stricture recurrence after the urethroplasty. Quitting smoking may be a good option for patients undergoing urethroplasty surgery.
ABSTRACT
Fibromyalgia syndrome (FMS), also known as fibromyalgia, is clinically characterized by diffuse chronic muscle and bone pain, accompanied by fatigue, sleep disturbances, depressive episodes, and cognitive and intestinal dysfunction. Due to lack of clear specific laboratory indicators and appropriate imaging examinations, FMS diagnosis is mostly based on clinical symptoms, but FMS clinical symptoms of lack specificity, and current clinical diagnostic criteria are mostly exclusive criteria, which is prone to missed diagnosis and misdiagnosis. In order to further promote the standardized diagnosis and treatment of FMS, this paper makes extensive references to laboratory-related diagnostic indexes of FMS (Tau, adiponectin, serum cathepsin S, cystatin C, serum ferritin, nitric oxide, neutrophil/lymphocyte ratio, platelet distribution width and mean platelet volume) at home and abroad, aiming to provide new ideas for early diagnosis and intervention of FMS.

ABSTRACT
As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

Allergic diseases affect about 40% of the world's population. Environmental factors are important in the occurrence and development of allergic diseases. Dust mites are one of the most important allergens in the indoor environment. The World Health Organization proposes the "four-in-one, combination of prevention and treatment" treatment principle for allergic diseases, in which environmental control to avoid or reduce allergens is the first choice for treatment. Modern people spend much more time at home (including sleeping) than outdoors, and the control of the home environment is particularly critical. This practice introduces the hypoallergenic home visit program, which including home environment assessment, environmental and behavioral intervention guidance, and common household hypoallergenic supplies and service guidance for the patient's home environment. The real-time semi-quantitative testing of dust mite allergens, qualitative assessments of other indoor allergens, record of patients' household items and lifestyle, and precise, individualized patient prevention and control education will be conducted. The hypoallergenic home visit program improves the doctors' diagnosis and treatment data dimension, and becomes a patient management tool for doctors outside the hospital. It also helps patients continue to scientifically avoid allergens and irritants in the environment, effectively build a hypoallergenic home environment, reduce exposure to allergens in the home environment, and achieve the goal of combining the prevention and treatment of allergic diseases.

Objective: To explore the characteristics and correlations of vaginal flora in women with cervical lesions. Methods: A total of 132 women, including 41 women diagnosed with normal cervical (NC), 39 patients with low-grade cervical intraepithelial neoplasia (CIN 1), 37 patients with high-grade cervical intraepithelial neoplasia (CIN 2/3) and 15 patients with cervical squamous cell carcinoma (SCC), who came from the gynecological clinic of Second Hospital of Shanxi Medical University during January 2018 to June 2018, were enrolled in this study according to the inclusive and exclusive criteria strictly. The vaginal flora was detected by 16S rDNA sequencing technology. Co-occurrence network analysis was used to investigate the Spearman correlations between different genera of bacteria. Results: The dominant bacteria in NC, CIN 1 and CIN 2/3 groups were Lactobacillus [constituent ratios 79.4% (1 869 598/2 354 098), 63.6% (1 536 466/2 415 100) and 58.3% (1 342 896/2 301 536), respectively], while Peptophilus [20.4% (246 072/1 205 154) ] was the dominant bacteria in SCC group. With the aggravation of cervical lesions, the diversity of vaginal flora gradually increased (Shannon index: F=6.39, P=0.001; Simpson index: F=3.95, P=0.012). During the cervical lesion progress, the ratio of Lactobacillus gradually decreased, the ratio of other anaerobes such as Peptophilus, Sneathia, Prevotella and etc. gradually increased, and the differential bacteria (LDA score >3.5) gradually evolved from Lactobacillus to other anaerobes. The top 10 relative abundance bacteria, spearman correlation coefficient>0.4 and P<0.05 were selected. Co-occurrence network analysis showed that Prevotella, Peptophilus, Porphyrinomonas, Anaerococcus, Sneathia, Atopobium, Gardnerella and Streptococcus were positively correlated in different stages of cervical lesions, while Lactobacillus was negatively correlated with the above anaerobes. It was found that the relationship between vaginal floras in CIN 1 group was the most complex and only Peptophilus was significantly negatively correlated with Lactobacillus in SCC group. Conclusions: The increased diversity and changed correlations between vaginal floras are closely related to cervical lesions. Peptophilus is of great significance in the diagnosis, prediction and early warning of cervical carcinogenesis.

【Objective】 To investigate the recurrence of patients with renal cell carcinoma (RCC) after robot-assisted partial nephrectomy (RAPN), and to explore the related factors of recurrence. 【Methods】 Clinical data of 367 RCC patients who underwent RAPN during 2015 and 2020 in our hospital were retrospectively collected. Patients were divided into recurrence group and non-recurrence group. The related factors of recurrence and 5-year cumulative recurrence rate of RCC and clear cell renal cell carcinoma (ccRCC) in the recurrence group were analyzed. 【Results】 The median follow-up was 48 (IQR:38-60) months. Recurrence occurred in 9 patients, with a 5-year cumulative recurrence rate of 97.5%. For RCC patients, univariate analysis showed that tumor size, T-stage, R. E. N. A. L. score, R value, N value, and operation time were significantly associated with postoperative recurrence (P<0.05), while multivariate analysis showed that N value (HR=15.75, 95%CI:2.00-124.17, P=0.009) was an independent related factor. For ccRCC patients, univariate analysis showed that hypertension, tumor size, T-stage, R. E. N. A. L. score, N value, operation time and WHO/ISUP grade were significantly associated with postoperative recurrence (P<0.05), while multivariate analysis showed that WHO/ISUP grade (HR=4.99, 95%CI:1.04-24.01, P=0.045) was an independent related factor. 【Conclusion】 The 5-year cumulative recurrence rate of RCC patients after RAPN is 2.5%. N value and WHO/ISUP grade are the independent related factor of recurrence of RCC and ccRCC, respectively.

The R. E. N. A. L score, E value, N value, L value, renal hilum position and T stage are influencing factors.
ABSTRACT
【Objective】 To compare the clinical efficacy of robot-assisted and open surgery in the treatment of renal carcinoma with inferior vena cava cancer thrombus, and to analyze the safety and feasibility of robot-assisted radical nephrectomy. 【Methods】 Clinical data of 55 patients surgically treated for renal carcinoma with Mayo Ⅰ-Ⅲ inferior vena cava tumor thrombus during Dec.2015 and Dec.2021 were retrospectively analyzed. Based on the operation methods, the patients were divided into the robotic surgery group (n=36) and open surgery group (n=19). The perioperative data, oncological results and survival of the two groups were compared. 【Results】 All operations were successful. The median operation time was 176 (IQR:137-234) min, and grade Ⅲ and above complications occurred in 9(16.4%) cases. The robotic surgery group had lower intraoperative blood loss [300 (IQR:200-625) mL vs.1 000 (IQR:600-1 184) mL] and blood transfusion ratio [(20/36) vs. (18/19)] than the open surgery group, but higher postoperative hemoglobin level[109(98-120) g/L vs. 90(84-100) g/L]. During a median follow-up of 26 (IQR:19-39) months, 19(34.5%) patients developed new metastases and 12(21.8%) patients died. The postoperative tumor-specific survival (HR=0.39, 95%CI:0.13-1.16, P=0.090) and overall survival (HR=0.71, 95%CI:0.22-2.23,P=0.554) were not significantly different between the two groups. 【Conclusion】 There are no significant differences in the incidence of postoperative complications, tumor-specific survival and overall survival between robot-assisted and open surgery for Mayo Ⅰ-Ⅲ inferior vena cava tumor thrombus, but the intraoperative blood loss in robotic group is lower than that in the open surgery group.
ABSTRACT
【Objective】 To compare the feasibility, safety, and efficacy of robot-assisted and open radical nephrectomy for complex kidney neoplasm >8 cm in diameter. 【Methods】 Clinical data of 24 patients with large kidney neoplasm undergoing robot-assisted radical nephrectomy (9 cases, 37.5%) and open radical nephrectomy (15 cases, 62.5%) during Nov.2015 and Aug.2019 were retrospectively analyzed. The surgical parameters, perioperative complications and follow-up outcomes were compared between the two groups. 【Results】 All operations were successful. Compared with the robot group, the open group had a higher incidence of clinical symptoms (93.3% vs.44.4%, P=0.015) and larger maximum tumor diameter (124 mm vs.95 mm, P=0.021). There were no significant differences in other preoperative characteristics between the two groups. The robot group had less intraoperative blood loss (100 mL vs.800 mL, P=0.006) and lower blood transfusion rate (0% vs. 60.0%, P=0.007) than the open group. During the median follow-up of 50 (range: 25-67) months, 4 patients in the open group and 1 in the robot group developed new metastases, and 4 patients in the open group died due to advanced tumor stage. 【Conclusion】 Robot-assisted radical nephrectomy is safe in the treatment of complex and large renal tumors, and causes less intraoperative blood loss than open surgery.
ABSTRACT
OBJECTIVE@#To evaluate the effectiveness and safety of Rotarex catheter system in treating femoropopliteal artery stenosis accompanied with thrombosis.@*METHODS@#From Jun. 2017 to Dec. 2019, the clinical data of 32 femoropopliteal artery stenosis accompanied with thrombosis cases treated with Rotarex catheter system were retrospectively analyzed. There were 23 males and 9 females aged from 50 to 89 years and the mean age was (70.7±10.3) years. Six cases had acute course of disease (≤2 weeks), 17 cases had subacute course of disease (>2 weeks, ≤3 months), and 9 cases had chronic course of disease (>3 months). Mean lesion length was (23.4±13.7) cm, mean occlusion length was (19.9±13.3) cm, and in-stent occlusion 7 cases. The superficial femoral artery (SFA) was involved in 13 cases, the popliteal artery (PA) was involved in 8 cases, and both SFA and PA were involved in the other 11 cases. All the cases were treated with Rotarex catheter system. When necessary, suction with large lumen catheter was enabled. Residual stenosis was treated with percutaneous transluminal angioplasty (PTA). Drug-coated balloon (DCB) was only used in patients with financial status, and stent was used only when it was necessary. Heparin was used for 24 h after procedures, and after that, antiplatelet agents were used. Doppler ultrasonography was taken during the followed-up.@*RESULTS@#Technical success was 100%, and mean procedure time was (107.4±21.5) min. 8F (1F≈0.33 mm) and 6F Rotarex catheter were used in 27 and 5 cases respectively. In 27 cases, forward flow was obtained immediately after debulking with Rotarex catheter, and in the other 5 cases, suction with large lumen catheters were used. PTA was used in all 32 cases. DCB were used in 8 cases, of which 4 were used in in-stent stenosis. Twelve cases were implanted stents. There were no perioperative deaths. The only one procedure related complication was distal embolism. We took out the thrombus with guiding catheter. In all cases, mean hospital stay were (4.6±1.5) d. The ankle brachial index increased from 0.32±0.15 to 0.86±0.10 after treatment (t=-16.847, P < 0.001). The Rutherford stages decreased significantly (Z=-4.518, P < 0.001). All the patients were followed up for 6.0-36.0 months, and the median time was 16.0 months. 2 cases stopped antiplatelet agents, which resulted in acute thrombosis. Another percutaneous mechanical thrombectomy and PTA were taken in one of them. Two cases died of cardiovascular disease during the follow-up, and no amputation was observed. Target lesion restenosis occurred in 7 cases during the follow-up, and target lesion revascularization (TLR) was taken in two of them.@*CONCLUSION@#In treating femoropopliteal artery stenosis accompanied with thrombosis, Rotarex catheter can remove thrombus effectively, and that can expose underlying lesions and reduce stent use and complications rates. It is a safe and effective method.

OBJECTIVE@#To explore whether the ethanol extract of Herpetospermum caudigerum Wall (EHC), a Xizang medicinal plant traditionally used for treating liver diseases, can improve imiquimod-induced psoriasis-like skin inflammation.@*METHODS@#Immunohistochemistry and immunofluorescence staining were used to determine the effects of topical EHC use in vivo on the skin pathology of imiquimod-induced psoriasis in mice. The protein levels of interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), and interleukin-17A (IL-17A) in mouse skin samples were examined using immunohistochemical staining. In vitro, IFN-γ-induced HaCaT cells with or without EHC treatment were used to evaluate the expression of keratinocyte-derived intercellular cell adhesion molecule-1 (ICAM-1) and chemokine CXC ligand 9 (CXCL9) using Western blotting and reverse transcription-quantitative polymerase chain reaction. The protein synthesis inhibitor cycloheximide and proteasome inhibitor MG132 were utilized to validate the EHC-mediated mechanism underlying degradation of ICAM-1 and CXCL9.@*RESULTS@#EHC improved inflammation in the imiquimod-induced psoriasis mouse model and reduced the levels of IFN-γ, TNF-α, and IL-17A in psoriatic lesions. Treatment with EHC also suppressed ICAM-1 and CXCL9 in epidermal keratinocytes. Further mechanistic studies revealed that EHC suppressed keratinocyte-derived ICAM-1 and CXCL9 by promoting ubiquitin-proteasome-mediated protein degradation rather than transcriptional repression. Seven primary compounds including ehletianol C, dehydrodiconiferyl alcohol, herpetrione, herpetin, herpetotriol, herpetetrone and herpetetrol were identified from the EHC using ultra-performance liquid chromatography-quadrupole-time of flight-mass spectrometry.@*CONCLUSION@#Topical application of EHC ameliorates psoriasis-like skin symptoms and improves the inflammation at the lesion sites.
