This study was aimed to investigate rules of medicine selections of four Meng-He (MH) medical schools. Based on frequency analysis and Apriori algorithm of association rules, data mining was conducted on 60 cases of four MH medical schools in the treatment of Chuan syndrome. The results showed that among 60 cases, Xing-Ren (XR), Ban-Xia (BX), Fu-Ling (FL), Hua-Ju-Hong (HJH), Su-Zi (SZ) and Bu-Gu-Zhi (BGZ) were the most com-monly used single medicine. The most commonly used medicine groups were SZ-HJH-FL, XR-Y i-Y i-Ren (YYR), XR-HJH, XR-SZ and so on. It was concluded that four MH medical schools in the treatment of Chuan syndrome mainly used antitussive and antiasthmatic Chinese medicines such as YR, BX, SZ, and complemented with BGZ for deficiency-nourishing, FL for dampness-removing, HJH for qi-regulating. It provided references for the clinical practice and treatment of Chuan syndrome.

Objective To evaluate clinical significance of the CEA, CA19-9, CA242, AFP, CA724,SCC, TPA, TPS combined detection for the clinical diagnosis of gastrointestial cancer. Methods 373 cases of upper digestive tract malignant tumor patient and 50 cases of healthy serum sample were detected for eight markers, evaluating the relationship between the level of markers and illness. Results 8 marker diagnostic positive rates were: CEA 26.80 %, CA19-9 27.34 %, CA242 34.14 %, AFP 2.84 %, SCC 19.72 %, CA724 12.13 %, TPA 34.15 %, TPS 30.89 %. The total positive rate of joint detection of 8 markers was 89.05 %.Preoperative CEA, CA242, SCC-positive patients had a shorter survival time. CA242 and CA19-9 levels with upper gastrointestinal malignancies were positively correlated. Conclusion The combined detection of a number of markers in different pathological type and clinical staging is statistically significant, and the positive rate is much higher than any single marker test results. CA19-9 and CA242 may be the best combination of monitoring the disease. CA724, CA242 and SCC can be as adverse prognostic indicators for cardia, stomach,esophageal malignant tumors, respectively.

Objectives:To study the pathological behavior and the value of transforming growth factor β1(TGF-β1) in predicting prognosis in pulmonary hypertension associated with congenital heart disease.　Methods:Lung tissues from 29 patients with congenital heart diseases associated with pulmonary hypertension were examined by surgical biopsy of the lung. All samples were examined for the expression and localization of TGF-β1 by immunohistochemical technique with anti-TGF-β1 antibody.　Results:Twenty-six out of 29 showed positive staining of intracellular endotheliocyte TGF-β1(89.65%),16 samples showed extracellular matrix TGF-β1 staining(55.17%).Statistically, there was significant difference between Ⅰ～Ⅱ and Ⅲ～Ⅵ pathological degrees in extracellular matrix(P<0.05).　Conclusions: TGF-β1 plays an important biological role in the formation of pulmonary hypertension after congenital heart disease. It is conductive in predicting prognosis.

Objective To investigate the clinical value of arterial first approach in laparoscopic pancreaticoduodenectomy (LPD).Methods The retrospective cohort study was conducted.The clinicopathological data of 181 patients with pancreatic head and periampullay tumors who underwent LPD in the Affiliated Tongji Hospital of Huazhong University of Science and Technology between October 2014 and December 2016 were collected.Among 181 patients,96 using arterial first approach and 85 using traditional approach were respectively allocated into the experimental group and the control group.Surgery was applied to patients in the same doctors' team,and there were the same extent of surgical resection,range of lymph node dissection and digestive tract reconstruction.Observation indicators:(1) intraoperative situation;(2) postoperative situation;(3) followup and survival situations.Follow-up using outpatient examination and telephone interview was performed to detect the tumor-free survival up to February 2017.Measurement data with normal distribution were represented as x±s,and comparison between groups was analyzed using the t test.Measurement data with skewed distribution were described as M (range).Comparison of count data were analyzed using the chi-square test or Fisher exact probability.Results (1) Intraoperative situation:all the patients underwent successful LPD.Overall operation time and time of digestive tract reconstruction were respectively (268 ± 20) minutes,(33 ± 10) minutes in the experimental group and (285±25)minutes,(30± 17)minutes in the control group,with no statistically significant difference between 2 groups (t =8.529,2.741,P＞ 0.05).Time of tumor resection with superior mesenteric venous invasion were respectively (216± 13)minutes and (264±22)minutes in the experimental and control groups,with a statistically significant difference between the 2 groups (t=41.826,P＜0.05).Time of tumor resection without superior mesenteric venous invasion were respectively (224± 14) minutes and (215±21) minutes in the experimental and control groups,with no statistically significant difference between the 2 groups (t =7.423,P＞ 0.05).Volumes of intraoperative blood loss and blood transfusion were respectively (99± 16)mL,(1.3±0.8)U in the experimental group and (131±27)mL,(2.8±1.2)U in the control group,with statistically significant differences between the 2 groups (t =3.670,0.562,P＜ 0.05).Five and 8 patients had intraoperative blood transfusion in the experimental and control groups,showing no statistically significant difference between the 2 groups (x2=1.195,P＞0.05).(2) Postoperative situation:time of drainage tube removal and duration of hospital stay were respectively (5.8±2.4)days,(18.3±6.3) days in the experimental group and (6.3±3.6)days,(19.6±7.1) days in the control group,with no statistically significant difference between the 2 groups (t =0.498,1.305,P＞0.05).Eleven patients in the experimental group had postoperative early complications,including 8with grade A pancreatic fistula (4 combined with diarrhea,2 combined with biliary fistula,1 combined with delayed gastric emptying and 1 with single pancreatic fistula),3 with grade B pancreatic fistula (2 combined with intra-abdominal hemorrhage and 1 combined with intra-abdominal infection).One patient with intra-abdominal hemorrhage in the experimental group died after treatment failure.Twelve patients in the control group had postoperative early complications,including 6 with grade A pancreatic fistula (2 combined with biliary fistula,2 combined with delayed gastric emptying,1 combined with diarrhea,1 combined with digestive tract hemorrhage),3 with grade B pancreatic fistula and intra-abdominal hemorrhage (2 combined with infection,including 1 death) and 3 with diarrhea.Other patients with complications were cured by symptomatic and supportive treatment.There was no statistically significant difference in overall complications between the 2 groups (x2 =0.287,P＞0.05).Results of postoperative pathological examination showed that case with R0 resection was 93 and 76 in the experimental and control groups,with a statistically significant difference between the 2 groups (x2 =4.057,P＜0.05).(3) Follow-up and survival situations:179 patients were followed up for 2-28 months,with a median time of 14 months.Postoperative 6-month tumor-free survival rate was 92.7％ (89/96) and 88.2％(75/85) in the experimental and control groups,with no statistically significant difference between the 2 groups (x2=1.060,P＞0.05).Conclusion Arterial first approach in LPD could significantly shorten the time of tumor resection of patients with superior mesenteric artery invading pancreatic head and periampullay region,significantly reduce the volumes of intraoperative blood loss and blood transfusion,and increase the rate of R0 resection.

Objective To explore the significance of 18 F-fluorodeoxyglucose positronemission tomography/ computed tomography (18F-FDG PET/CT) scanning for childhood neuroblastoma clinical staging.Methods From December 2014 to December 2015,59 patients confirmed as NB in Beijing Children's Hospital,Capital Medical University,and finding or clinical features were selected by histopathology.Those patients underwent 18 F-FDG PET/CT,bone scan,cranial magnetic resonance image (MRI),bone marrow puncture (two sites) and biopsy,regional CT,ultrasound,serum tumor markers like lactic dehydrogenase and neuronspecific enolase.In comparison of 18F-FDG PET/CT image findings with other detective methods,the differences were analyzed between the primary sites and metastasis were analyzed.Results (1) General features:Out of 59 children with NB,31 were males,28 were females.Primary lesions were as follows:14 cases located in the postmediastinum,44 cases in the retroperitoneum (1 case in retroperitoneum + postmediastinum),1 case in left neck.International Neuroblastoma Staging System Ⅰ to Ⅳ:O,1,9 and 49 cases,respectively.(2)18F-FDG PET-CT manifestations:The maximum of standardized uptake value (SUVmax):before-treatment group was (2.34 ± 1.06) which was larger than the post-surgery group value of (1.08 ± 0.50),and the difference was significant(F =5.699,P =0.000);bone marrow metastasis ranged from 1.5 to 2.9,regional lymphatic metastasis ranged from 1.0 to 2.1.(3)18F-FDG PET-CT imaging compared with other detection:in bone metastases,the whole body bone scan finding were normal in 3 cases,while PET/CT showed disseminated bone and bone marrow involvement and bone scanning showed 2 cases had metastases,combined with 18 F-FDG PET/CT,which were considered as postoperative inflammatory reaction or residual tumor tissues invade adjacent intervertebral foramen.Bone cytology was positive in 30 cases,while PET/CT showed 34 patients with bone marrow metastasis,and 1 case was suspicious.In central metastasis,1 case of PET/CT showed epidural metastasis,while cranial MRI was negative;Cranial MRI showed 9 cases had skull metastasis,1 case had orbital metastasis,1 case had meningeal metastases;while 18F-FDG PET/CT showed no abnormality.All children had no parenchymal metastasis.Corresponding tumor markers as LDH was related to the maximum value of primary tumor focal SUVmax (rs =0.581,P ＜ 0.01).Conclusions 18 F-FDG PET/CT can fully display the distribution of primary sites and metastases,and can be served as medical imaging evidence for both the diagnosis and staging of neuroblastoma.But as for cranial bone and central metastasis,it has high false negative rate.Clinical practice should be combined with cranial MRI to improve relevance ratio.

Objective:To investigate the clinical value of applying pain tolerance index(PTi) to guide multimodal analgesic regimen during the perioperative period in elderly hip fractures.Methods:A total of 100 elderly patients with hip fracture admitted to Fuyang People′s Hospital from April 2022 to April 2023 were selected as the study objects. The patients were underwent hip replacement and were divided into two groups according to the different analgesic methods used during the operation. The control group (50 cases) was given routine analgesia during the operation, and the experimental group (50 cases) was given multimode analgesia under the guidance of PTi during the operation. The anesthetic analgesic effect, hemodynamic indexes, inflammatory factors, visual analogue scale (VAS) score, hip function and analgesic drug application were compared between the two groups.Results:The excellent rate of anesthesia and analgesia in the experimental group was higher than that in the control group: 96.00%(48/50) vs. 82.00%(41/50), there was statistical difference ( χ2 = 5.00, P<0.05). The fluctuation ranges of mean arterial pressure (MAP) and heart rate (HR) at the beginning of operation, 30 min after operation and the end of operation in the experimental group were lower than those in the control group ( P<0.05). The serum levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in the experimental groups were lower than those in the control group at 1 and 3 d after operation ( P<0.05). The scores of VAS at 24, 48 and 72 h after operation in the experimental group were lower than those in the control group ( P<0.05). The total scores of Harris questionnaire in the experimental group was higher than that in the control group at 6 weeks after operation: (85.93 ± 3.22) scores vs. (75.19 ± 4.18) scores, there was statistical difference ( P<0.05). The intraoperative dosage of propofol and sufentanil and the number of postoperative analgesic drugs in the experimental groups were lower than those in the control group: (430.61 ± 20.09) mg vs. (475.58 ± 23.17) mg, (33.24 ± 8.11) μg vs. (42.90 ± 9.64) μg, (1.54 ± 0.31) times vs. (2.07 ± 0.44) times, there were statistical differences ( P<0.05). The incidence of nausea and vomiting in the experimental group was lower than that in the control group: 2.00% (1/50) vs. 14.00% (7/50), there was statistical difference ( χ2 = 4.89, P<0.05). Conclusions:The application of PTi guided multimodal analgesia in elderly hip fracture surgery has a definite clinical effect, can maintain hemodynamic stability, reduce postoperative inflammatory stress and pain, promote hip joint function recovery, and has certain safety.

Objective To explore the significance of the initial clinical symptoms and clinical manifestations of neuroblastoma(NB)to achive early identification of NB. Methods A retrospective study was performed on patients diagnosed with NB,who attended the Hematology Oncology Center,Beijing Childrenˊs Hospital from March 31st ,2007 to March 31st,2015. The clinical characteristics were compared between the children 〈1_year_old and≥1_year_old. The result was analyzed to compare the difference in clinical symptoms and tumor biologic characteristics of patients with different initial clinical symptoms between 2 groups. Results A total of 330 patients were included in the study,43 of them were younger than 1 year old,and their most common symptoms were cough and fever( each 17 cases,and accounted for 39. 5%,respectively);while the most common symptoms in patients≥1_year_old(287 cases)was fe_ver(177 cases,61. 7%),followed by lymphadenopathy(107 cases,37. 3%),bone pain(97 cases,33. 8%)and anemia (48 cases,16. 7%). The frequency of symptoms differed significantly between 2 groups(all P〈0. 05),such as fever (39. 5% vs. 61. 7%,χ2 ﹦6. 68),anemia(4. 7% vs. 16. 7%,χ2 ﹦6. 00),bone pain(0 vs. 33. 8%,χ2 ﹦18. 99),abdo_minal pain(0 vs. 25. 3%,χ2 ﹦10. 19),diarrhea(16. 3% vs. 3. 0%,χ2 ﹦12. 73),lymphadenopathy(7. 0% vs. 37. 3%, χ2 ﹦14. 12)and anorexia(9. 3% vs. 33. 4%,χ2 ﹦9. 21). Datients had fever,anemia,lymphadenopathy,cutaneous hemorrhagic spot or periorbital ecchymosis,bone pain,abdominal pain,exophthalmos,and anorexia early in the initial course of the disease,whose serum lactate dehydrogenase values were significantly increased(P〈0. 05). Datients suf_fered from fever,anemia,lymphadenopathy,bone pain,limbs dysfunctions,abdominal pain at the beginning of the disease,whose urine vanillymandelic acid values were higher than normal(P〈0. 05). Conclusions The study of sympto_mology suggests the most common symptoms in patients with NB 〈1_year_old are cough and fever,while those ≥1_year_old are fever,lymphadenopathy,bone pain,and anemia. Por patients with symptoms mentioned,carrying out the necessary NB_diagnose_related laboratory and imaging studies was statistically relevant to patientsˊ ages(〈1_year_old and≥1_year_old),which may contribute to earlier identification and diagnosis of NB.

Objective:To explore the clinical efficacy of different doses of apatinib combined with chemotherapy in patients with advanced non-small cell lung cancer (NSCLC) and the adverse reactions.Methods:A total of 69 patients with NSCLC diagnosed in the No. 901 Hospital of the Chinese People′s Liberation Army Joint Logistics Support Force were selected from January 2018 to June 2020, and were divided into chemotherapy alone group (docetaxel+ cisplatin was used), apatinib group A [apatinib (0.25 g)+ docetaxel+ cisplatin was used] and apatinib group B [apatinib (0.50 g)+ docetaxel+ cisplatin was used] according to random number table method, with 23 cases in each group. The objective response rate (ORR), disease control rate (DCR), median overall survival (OS), median progression-free survival (PFS), and incidences of adverse reactions were compared between the three groups of patients.Results:One patients in the apatinib group B withdrew from the study due to acute myocardial infarction. After 4 cycless of treatment, the ORR of the patients in the chemotherapy alone group, apatinib group A and apatinib group B were 17.39% (4/23), 47.83% (11/23) and 54.55% (12/22) respectively, with a statistically significant difference ( χ2=7.41, P=0.024). The ORR of the apatinib group B was higher than that of the chemotherapy alone group, with a statistically significant difference ( χ2=6.77, P=0.009). There were no statistically significant differences in ORR between the apatinib group A and chemotherapy alone group, the apatinib group A and apatinib group B ( χ2=4.85, P=0.028; χ2=0.20, P=0.652). The DCR of the patients in the three groups were 47.83% (11/23), 78.26% (18/23) and 86.36% (19/22) respectively, with a statistically significant difference ( χ2=9.03, P=0.011). The DCR of the apatinib group B was higher than that of the chemotherapy alone group, with a statistically significant difference ( χ2=7.52, P=0.006). There were no statistically significant differences in DCR between the apatinib group A and the chemotherapy alone group, the apatinib group A and apatinib group B ( χ2=4.57, P=0.033; χ2=0.51, P=0.477). The median OS of the patients in the three groups were 6.8, 9.2 and 9.9 months respectively, with a statistically significant different ( χ2=8.91, P=0.022). Compared with the chemotherapy alone group, the median OS of the apatinib group A and apatinib group B were significantly prolonged, with statistically significant differences ( χ2=7.25, P=0.036; χ2=8.60, P=0.029). Compared with the apatinib group A, the median OS of the apatinib group B was prolonged, but there was no statistically significant different ( χ2=1.54, P=0.201). The median PFS of the patients in the three groups were 5.2, 7.7 and 8.2 months respectively, with a statistically significant different ( χ2=8.79, P=0.026). Compared with the chemotherapy alone group, the median PFS of the apatinib group A and apatinib group B were significantly prolonged, with statistically significant differences ( χ2=7.01, P=0.039; χ2=8.36, P=0.031). Compared with the apatinib A group, the median PFS of the apatinib group B was prolonged, but there was no statistically significant different ( χ2=1.68, P=0.186). There were statistically significant differences in the incidences of fatigue [34.78% (8/23) vs. 65.22% (15/23) vs. 72.73% (16/22), χ2=7.50, P=0.024], hypertension [4.35% (1/23) vs. 34.78% (8/23) vs. 68.18% (15/22), χ2=20.07, P<0.001], hand-foot syndrome [4.35% (1/23) vs. 43.48% (10/23) vs. 72.73% (16/22), χ2=22.28, P<0.001] and oral mucositis [8.70% (2/23) vs. 39.13% (9/23) vs. 72.73% (16/22), χ2=19.26, P<0.001] among the three groups. Compared with the chemotherapy alone group, the incidences of hypertension and hand-foot syndrome in the apatinib group A and the incidences of fatigue, hypertension, hand-foot syndrome and oral mucositis in the apatinib group B were increased, with statistically significant differences ( χ2=6.77, P=0.009; χ2=9.68, P=0.002; χ2=6.51, P=0.011; χ2=20.00, P<0.001; χ2=22.37, P<0.001; χ2=19.21, P<0.001). Conclusion:Apatinib (0.50 g) combined with chemotherapy has better short-term efficacy than chemotherapy alone in advanced NSCLC. Apatinib (0.25 g) and apatinib (0.50 g) can prolong the survival of patients, but increasing the treatment dose can not achieve longer survival benefit.
