Objective To observe the anti-tumor action of Fuzheng Yuliu Tablet(FYT).Methods Mice received subcutaneous injection of S180 into right axilla.Then the tumor-implanted mice were randomized into 6 groups: model group,FYT groups(at the dose of 2.4 and 12.4g/kg respectively),cisplatin group(at the dose of 8?g/d),and cisplatin+FYT groups.The treatment lasted 10 days.The tumor-inhibitory rate and the life-prolongation rate were observed after treatment.The cultured ovarian cancer cell strains of SKOV3 were randomized into 4 groups:model group,two FYT groups and cisplatin group.Apoptosis of SKOV3 was detected by enzyme-linked immunosorbent assay(ELISA)after culturing with the medicine for 48 hours.Results The tumor growth was inhibited to different extends in all of the treatment groups,the decrease of tumor mass weight was obvious in cisplatin group and FYT groups,and the body weight was increased in FYT groups and cisplatin+FYT groups(P

Objective To summarize the clinical manifestations,pathological character,diagnosis and treatment of aggressive angiomyxoma (AAM).Methods A computer-based online search of PubMed database and CHKD database was undertaken for literature about AAM published from all the relevant documents with the key words of aggressive angiomyxon.According to the condition 210 articles were analyzed.All the articles were analyzed about natural history,clinical manifestation,diagnosis,pathological character,treatment and prognosis of AAM.Results A total of 282 cases in well-documented articles had been reported,among which 64 were male and 218 were female,with male to female ratio of 1:3.4.The age of the patients from 1 to 83 years(mean 40.38 years).The most common sites were the perineum,genital tract and soft tissue in pelvic cavity in females and the scrotum,spermatic cord and groin in males.None of the cases could be accurately diagnosed as AAM preoperatively.The minimum diameter of the tumors was 1 cm,and the maximum was 60 cm.All the specimens showed typical pathological features of AAM as reported previously.Immunohistochemistry indicated that AAM tended to be strongly positive for vimentin,CD34,Desmin,estrogen receptor,progesterone receptor but mostly negative for S-100 and Ki-67 and Actin.The medical history was from 1 month to 20 years.The recurrence of the postoperative follow-up was 2 months to 20 years.The diagnosis depended on pathological examination.Conclusions AAM is a sort of unusual soft connective tissue tumor.It is a kind of unknown cause,slow progression,locally invasive,easy to recur after tumor resection.Long-term follow-up is quite necessary because of the high rate of local recurrence.

Objective:To investigate the expression of hypoxia-inducible factor-2α (HIF-2α)in non-small cell lung cancer (NSCLC)tissue,and to analyze its relationships with angiogenesis,cell proliferation and chemotherapy resistance. Methods: Total 112 cases of NSCLC and 20 cases of normal lung tissues were selected, immunohistochemical method was used to detect the expressions of HIF-2α,CD31,Ki67 and GST-π in 112 cases of cancer tissue and 20 cases of normal lung tissue,and the correlations of HIF-2α expression with microvessel density (MVD),Ki67, and GST-π were analyzed.Results:The positive expression rate of HIF-2α in NSCLC tissue was significantly higher than that in normal lung tissue (P < 0.05 ), the expression rate of HIF-2α in 112 cases of NSCLC was 47.3% (53/112).The MVD in HIF-2α protein high expression NSCLC group (31.1 ± 14.7)was higher than that in HIF-2αprotein low expression NSCLC group (24.3±15.8)(P <0.05).The cases of high expression of Ki67 in HIF-2αhigh expression group occupied 54.7% (29/53),and it was higher than that in HIF-2αlow expression group (16/59,27.1%);there was significant difference (r = 0.281,P = 0.003).The high expression of HIF-2α had no obvious correlation with the expression of GST-π (r = 0.122,P = 0.202). Conclusion:HIF-2αmay play an important role in the carcinogenesis and development of NSCLC by promoting the angiogenesis and enhancing the cell proliferation of NSCLC,but it may have no correlation with chemotherapy resistance.

Objective To assess the level and trend of community acquired respiratory distress syndrome (CARDS) toxin after the infection of Mycoplasma pneumonia(MP),and evaluate the clinical characteristics,the level of immunoglobulin E (IgE) and interleukin-4 (IL-4) so as to find the association among these factors.Methods According to whether the child had wheezing symptoms,all the 63 children were divided into wheezing group (26 ca-ses) and non-wheezing group (3 cases).The levels of CARDS toxin were respectively detected in the acute stage of MP infection,3 and 6 months later after MP infection in different groups,moreover,IgE and IL-4 levels were monitored at the same time.Results (1) The mean level of IgE were (384.96 ± 316.62) × 103 IU/L and (87.32 ± 66.32) × 103 IU/L in wheezing group and non-wheezing group,respectively,and there was statistically significant difference (P ＜ 0.05).(2) The load of CARDS toxin in wheezing group and non-wheezing group were (1.87 ± 0.62) Delta Rn and (1.15 ± 0.48) Delta Rn in the stage of acute infection,respectively,and there was statistically significant difference (P ＜ 0.05).Nevertheless,differences between 2 groups after 3 months and 6 months were not significant.(3) In the acute stage,the level of CARDS toxin in the severe cases were higher than the mild cases [(2.37 ± 0.37) Delta Rn vs (1.21 ± 0.45) Delta Rn],and there was statistically significant difference (P ＜ 0.05).(4) IL-4 showed significant difference in the acute stage and 3 months later after acute infection between 2 groups,however,there were no difference between 2 groups after 6 months later.(5)The load of CARDS toxin showed no significant difference between 2 groups at 3 months [(0.96 ± 0.35) vs.(0.99 ± 0.40) Delta Rn,P =0.757] and 6 months [(0.67 ± 0.20) vs.(0.69 ±0.32) Delta Rn,P =0.641] later after MP infection.(6)The children in wheezing group coughed for (24.89 ±7.04) days after acute infection and the last time for non-wheezing group was (16.46 ± 4.79) days,and there was statistically significant difference(P =0.000).Conclusions The load of CARDS toxin decreased after acute MP infection and it was still detectable six months after onset in the blood.The level of CARDS toxin was associated with the cough and wheezing symptom and the severity of disease.

Objective:To investigate the risk factors of lower extremity deep venous thrombosis (LEDVT) in patients with sepsis during hospitalization in intensive care unit (ICU), and to construct a nomogram prediction model of LEDVT in sepsis patients in the ICU based on the critical care scores combined with inflammatory markers, and to validate its effectiveness in early prediction.Methods:726 sepsis patients admitted to the ICU of the Affiliated Hospital of Jining Medical University from January 2015 to December 2021 were retrospectively included as the training set to construct the prediction model. In addition, 213 sepsis patients admitted to the ICU of the Affiliated Hospital of Jining Medical University from January 2022 to June 2023 were retrospectively included as the validation set to verify the performance of the prediction model. Clinical data of patients were collected, such as demographic information, vital signs at the time of admission to the ICU, underlying diseases, past history, various types of scores within 24 hours of admission to the ICU, the first laboratory indexes of admission to the ICU, lower extremity venous ultrasound results, treatment, and prognostic indexes. Lasso regression analysis was used to screen the influencing factors for the occurrence of LEDVT in sepsis patients, and the results of Logistic regression analysis were synthesized to construct a nomogram model. The nomogram model was evaluated by receiver operator characteristic curve (ROC curve), calibration curve, clinical impact curve (CIC) and decision curve analysis (DCA).Results:The incidence of LEDVT after ICU admission was 21.5% (156/726) in the training set of sepsis patients and 21.6% (46/213) in the validation set of sepsis patients. The baseline data of patients in both training and validation sets were comparable. Lasso regression analysis showed that seven independent variables were screened from 67 parameters to be associated with the occurrence of LEDVT in patients with sepsis. Logistic regression analysis showed that the age [odds ratio ( OR) = 1.03, 95% confidence interval (95% CI) was 1.01 to 1.04, P < 0.001], body mass index (BMI: OR = 1.05, 95% CI was 1.01 to 1.09, P = 0.009), venous thromboembolism (VTE) score ( OR = 1.20, 95% CI was 1.11 to 1.29, P < 0.001), activated partial thromboplastin time (APTT: OR = 0.98, 95% CI was 0.97 to 0.99, P = 0.009), D-dimer ( OR = 1.03, 95% CI was 1.01 to 1.04, P < 0.001), skin or soft-tissue infection ( OR = 2.53, 95% CI was 1.29 to 4.98, P = 0.007), and femoral venous cannulation ( OR = 3.72, 95% CI was 2.50 to 5.54, P < 0.001) were the independent influences on the occurrence of LEDVT in patients with sepsis. The nomogram model was constructed by combining the above variables, and the ROC curve analysis showed that the area under the curve (AUC) of the nomogram model for predicting the occurrence of LEDVT in patients with sepsis was 0.793 (95% CI was 0.746 to 0.841), and the AUC in the validation set was 0.844 (95% CI was 0.786 to 0.901). The calibration curve showed that its predicted probability was in good agreement with the actual probabilities were in good agreement, and both CIC and DCA curves suggested a favorable net clinical benefit. Conclusion:The nomogram model based on the critical illness scores combined with inflammatory markers can be used for early prediction of LEDVT in ICU sepsis patients, which helps clinicians to identify the risk factors for LEDVT in sepsis patients earlier, so as to achieve early treatment.

Objective To investigate the effects of two different oxygen therapies (oxygen time<4 h/d, oxygen flow>6 L/minversus oxygen time>4 h/d, oxygen flow<6 L/min) on conservative treatment of spontaneous pneumothorax by meta-analysis. Methods The following electronic databases as PubMed, The Cochrane Library, Web of Science, Chinese Biomedical Literature Database, WanFang Database and China National Knowledge Database were retrieved on computer for randomized controlled trials (RCTs) of comparing two different oxygen therapies (oxygen time<4 h/d, oxygen flow>6 L/minversus oxygen time>4 h/d, oxygen flow<6 L/min) on conservative treatment of spontaneous pneumothorax. The retrieval time was from inception of each database to December 2017. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies. Then data were analyzed by RevMan 5.3 software. Results A total of 4 RCTs involving 226 patients were included. The meta-analysis showed that compared with lower oxygen flow (oxygen time>4 h/d, oxygen flow<6 L/min), the higher oxygen flow (oxygen time<4 h/d, oxygen flow>6 L/min) could obviously decrease the degree of pulmonary compression after oxygen therapy for 5 days (MD=–2.81, 95%CI –4.18 to –1.44, P<0.05), shorten duration of hospital stay (MD=–3.26, 95%CI –6.05 to –0.47, P<0.05) and duration of recruitment maneuvers (MD=–2.78, 95%CI –5.27 to –0.28, P<0.05), but there was no significant difference in oxygen partial pressure after oxygen therapy for 5 days (MD=10.68, 95%CI –7.03 to 28.39, P=0.24). Conclusion The higher oxygen flow (oxygen time<4 h/d, oxygen flow>6 L/min) can obviously decrease the degree of pulmonary compression after oxygen therapy for 5 days, shorten duration of hospital stay and duration of recruitment maneuvers, but the results are influenced by the number and quality of RCT.
