OBJECTIVETo compare the difference in clinical efficacy on children attention deficit hyperactivity disorder (ADHD) between the combined therapy of scalp acupuncture and EGG biofeedback and the simple EEG biofeedback therapy so as to search the better therapeutic method for ADHD.

METHODSOne hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the simple EEG biofeedback therapy was adopted. In the observation group, on the basis of biofeedback therapy, scalp acupuncture was added and applied to Dingzhongxian (MS 5), Dingpangyixian (MS 8), Baihui (GV 20), Sishencong (EX-HN 1), etc. The ten treatments made one session. After four sessions of treatment, FIQ value in Wechsler intelligence scale, CIH score in Conners children behavior questionnaire, the ratio of 0 wave and p wave in EEG, FRCQ and FAQ in the integrated visual and auditory continuous performance test (IVA-CPT) and clinical comprehensive efficacy were observed before and after treatment in the two groups separately.

RESULTSThree cases were dropped out in the observation group and 2 cases were out in the control group. In the two groups, FIQ, FRCQ and FAQ were all increased after treatment (P < 0.01, P < 0.05); the increases in the observation group were much more significant than those in the control group after treatment (all P < 0.05). In the two groups, CIH score and the ratio of 0 wave and p wave were all reduced after treatment (P < 0.01, P < 0.05); the reduction in the observation group were much more apparent as compared with those in the control group (both P< 0.05). The total effective rate was 91.5% (43/47) in the observation group and better than 83. 3% (40/48, P < 0.01) in the control group.

CONCLUSIONThe combined therapy of scalp acupuncture and EEG biofeedback achieves the superior efficacy on children ADHD as compared with the simple biofeedback therapy. This combined therapy rapidly relieves the essential symptoms of ADHD and improves EEG waveform in children patients. Importantly, this therapy obtains and consolidates the significant efficacy.

Objective To observe the clinical effect of oral administration of Fufangejiao liquid after drug-induced abortion. Methods A total of 120 women within 7 weeks' of gestation, who needed to terminate pregnancy and asked for drug-induced abortion, were evenly randomized into two groups: experimental group and control group. The experimental group was given Fufangejiao liquid (20ml, tid, for 7 days) after the drug-induced abortion; the control group was given Chanfukang particles (lOg, tid, for 7 days) after drug-induced abortion. The drug-induced abortion and amount of bleeding were observed in the two groups. Results (1) The complete abortion rate was 90. 0%(54 cases) in the experimental group and 86. 7% (52 cases) in the control group. (2) There were 88. 9%(48/ 54 cases) of the patients in the experimental group and 76. 9% (40/52) in the control group had a similar bleeding amounts to the usual menstrual amount. There were 9. 3%(5 cases) of the patients in the experimental group and 19. 2%(10 cases) in the control group had more bleeding (≤1 fold) than the usual menstrual amount(P<0. 05). (3)The days of bleeding, bleeding amount, and menstrual onset were similar in the two groups. Conclusion Administration of Fufangejiao liquid after drug-induced abortion can reduce the amount of bleeding after abortion and is therefore worth popularizing.

Human brain natriuretic peptide (hBNP) was used clinically for the treatment of acute decompensated congestive heart failure. In this paper, hBNP was expressed as a fusion protein with a histidine tag and Ssp dnaB mini-intein which was capable of self-cleavage. After affinity chromatography with Ni-Sepharose and renaturation, the fusion protein was enriched with CM-cellulose. Ssp dnaB mini-intein mediated peptide-bond hydrolysis was triggered by shifting the pH and temperature in the CM-cellulose column, which let to the release of hBNP from the fusion protein and the separation of hBNP from His-DnaB. The hBNP sample was further purified by C4 reverse phase HPLC, and 2.8mg of the peptide with homogeneity of 97% was obtained from one liter of culture medium. The biological activity was assayed in vitro, which indicated that hBNP had a potent vasodilatory effect on rabbit aortic strips with an EC50 of 1.94 x 10(-6) mg/mL.

OBJECTIVETo analyze the clinical, imaging and pathological findings of congenital intrapulmonary lymphangioma and hemangioma in 5 infants and young children.

METHODData of 3 cases with congenital intrapulmonary lymphangioma and 2 cases with haemangioma were analyzed.

RESULTAll the 5 cases had cough, difficulty in breathing, cyanosis of lips, and shortness of breath. Imaging study indicated cystic and space occupying changes of partial lung. In the two cases of hemangioma, the blood vessels passing through the hemangioma were observed on CT films. Histochemical studies showed that the cystic pockets from removed tissues were different in size and there was a line of flat endothelial tissue around these pockets. Immunochemical studies indicated D2-40 positive, factor VIII weak positive for lymphangioma cases; while in hemangioma cases, factor VIII was positive, D2-40 was negative or weakly positive, and both of cytokeratin was negative.

CONCLUSIONIt is very important to consider and identify congenital intrapulmonary lymphangioma or hemangioma when a patient has cystic pockets and space occupying change in their lung by imaging and pathological studies.

Objective:To analyze the risk factors of lymph node metastasis of distal cholangiocarcinoma.Methods:We retrospectively analyzed the clinical data of 123 patients of distal cholangiocarcinoma in Beijing Chaoyang Hospital between Jan 2011 and Dec 2019. All patients underwent pancreatoduodenectomy. The prognosis was evaluated according to the follow-up results. The survival rate was compared by log-rank test. Logistic regression was used to analyze the risk factors for lymph node metastasis.Results:One hundred and twenty-three patients successfully underwent the operations, 6 patients died during the perioperative time. The overall 1-year, 3-year and 5-year survival rates were 75.2%, 41.9% and 31.5%. The median survival time was 44.7 months. Fifty-one patients had lymph node metastasis, and the rate of lymph node metastasis was 41.5%. The median survival time was 55.5 months and 27.5 months for patients without and with lymph node metastasis, respectively. Correspondingly, the survival rates of 1-year, 3-year, 5-year were 83.0%, 50.7%, 42.5% vs. 63.5%, 19.0%, 19.0% ( P=0.000). Multivariate analysis showed that preoperative CA19-9 ( RR=7.064, 95% CI: 2.489-20.051) and portal venous system invasion ( RR=4.610, 95% CI: 1.252-16.972) were independent risk factors for lymph node metastasis. Conclusions:Lymph node metastasis is an important factor affecting the long-term survival of patients with distal cholangiocarcinoma. Preoperative CA19-9 level and portal venous system invasion are independent risk factors for lymph node metastasis.

Objective:To further understand the current status of diagnosis and treatment of endometriosis in China, the implementation of guideline in different levels of hospitals, and the need for continuing education in endometriosis among primary doctors.Methods:The survey was conducted in the form of convenience sampling questionnaire among the Wechat public platform. The doctors were free to participate in the investigation without any reward. All questions answered were assessed as valid questionnaire. The datas were collected on the questionnaire network platform and analyzed by SPSS 19.0.Results:Totally 1 494 valid questionnaires were collected in this survey. 60.17% (899/1 494) of them were from tertiary hospital, and 32.60% (487/1 494) were from grade two hospital. Only the hospitals where 9.97% (149/1 494) participants based opened the specialist clinic for endometriosis. 70.35% (1 051/1 494) of participants said they had read the second edition of guideline for the diagnosis and treatment of endometriosis which published in 2015. The American Society for Reproductive Medicine (ASRM) staging system was adopted in the clinical practices of only 25.03% (374/1 494) participants. And 18.74% (280/1 494) participants used the endometriosis fertility index (EFI) scoring during the laparoscopic surgery for endometriosis with infertility. 45.18% (675/1 494) of participants said they had not attended any academic conference on endometriosis in the past six months. 64.46% (963/1 494) of the participants believed their diagnosis and treatment in practice should be improved and standardized. 87.15% (1 302/1 494) of the participants expressed the hope that more conferences or workshops on endometriosis would be held.Conclusions:At presents, the diagnosis and treatment of endometriosis in China has been greatly improved, but the implementation of guidelines and the new concept is still a long-term job. The specialist clinic are held only in a few hospitals. It’s the expectation and voice of primary doctors to the association to organize the more academic congresses on endometriosis.

Objective:To evaluate the prognosis and related risk factors in patients who underwent surgical resection for pancreatic cancer with portal vein invasion.Methods:The clinical data of 66 patients with pancreatic cancer with portal vein invasion who underwent pancreatic combined with vascular resection and reconstruction at the Department of Hepatobiliary Surgery, Beijing Chaoyang Hospital Affiliated to Capital Medical University between January 2011 and December 2018 were retrospectively studied. There were 30 males and 36 females. Their age ranged from 35 years to 81 years, with a mean of 61.5 years. Post-operative survival outcomes were evaluated on follow-up, and the related risk factors for prognosis were analyzed. Kaplan-Meier method was used to construct survival curves, and the survival rates were compared by the log-rank test. Multivariate Cox regression was used to analyze prognostic factors.Results:All 66 patients successfully underwent the operations. There was no perioperative death. The postoperative complication rate was 28.8% (19/66). Sixty-five patients were followed up (follow-up rate 98.5%, 65/66). The overall 1-, 2- and 3-year survival rates were 53.3%, 30.4%, 23.4%, respectively, with a median survival of 13 months. Multivariate analysis showed that preoperative CA19-9 >400 U/ml ( RR=1.871, 95% CI: 1.123-3.117) and depth of venous invasion ( RR=1.713, 95% CI: 1.072-2.736) were independent risk factors of prognosis. The higher the preoperative CA19-9, and the deeper the venous invasion, the worse was the prognosis. Conclusion:Long-term prognosis of pancreatic carcinoma patients with portal vein invasion was poor. Preoperative CA19-9 >400 U/ml and depth of vascular invasion were the main risk factors of prognosis for patients with pancreatic carcinoma and portal vein invasion after surgical resection.

Objective:To detect the changes of left ventricular myocardial work parameters, and evaluate the left ventricular systolic function in patients with hyperglycemia during pregnancy by left ventricular pressure-strain loop (PSL).Methods:From June 2021 to March 2022, 97 pregnant women who were admitted to the Second Affiliated Hospital of Harbin Medical University and clinically diagnosed as gestational hyperglycemia were prospectively and randomly selected. According to the blood glucose level, the patients were divided into gestational dominant diabetes mellitus (ODM) group(39 cases) and gestational diabetes mellitus (GDM) group(58 cases). Meanwhile, another 62 healthy pregnant women were selected as control group. The basic clinical data of the pregnant women were collected, and the conventional two-dimensional parameters of the heart were collected. The global longitudinal strain (GLS) was analyzed by two-dimensional speckle tracking technique. Then the cuff blood pressure was used as the left ventricular pressure to construct a non-invasive left ventricular pressure-strain loop. The global myocardial work index (GWI), global constructive work (GCW), global wasted work (GWW) and global work efficiency (GWE) of each group were calculated and compared. The correlation between myocardial performance parameters and GLS, glycated hemoglobin(HbA 1c) were analyzed, and the independent factors affecting left ventricular systolic function were obtained by Logistic regression analysis. Twenty cases were randomly selected from the study subjects, and the intraclass correlation coefficients(ICC) of within the observers and between observers were calculated for repeatability test. Results:①Conventional ultrasound parameters: There were no significant differences among the three groups (all P>0.05). ②GLS and left ventricular myocardial performance parameters: GWI, GWE, GCW and GLS in GDM and ODM groups were significantly lower than those in control group (all P<0.001), GWW was significantly higher than control group ( P<0.001); GWI, GWE, GCW and GLS in ODM group were lower than those in GDM group (all P<0.001), while GWW was higher than control group ( P<0.001). ③GWE, GWI and GCW were negatively correlated with GLS ( r=-0.525, -0.408, -0.435; all P<0.05), GWW was positively correlated with GLS ( r=0.348, P<0.05). GWE, GWI and GCW were negatively correlated with HbA 1c ( r=-0.325, -0.262, -0.250; all P<0.05), while GWW was positively correlated with HbA 1c ( r=0.175, P<0.05). ④GWE, 1 h oral glucose tolerance test and HbA 1c were the influencing factors of left ventricular systolic function in patients with hyperglycemia during pregnancy. ⑤The predictive values of GWI, GWE, GCW, GWW and GLS for cardiac function in patients with gestational hyperglycemia were high, and the predictive value of GWE was the highest (AUC: 0.87, the best truncation value: 94.5%, specificity: 0.76, sensitivity: 0.82) and better than GLS. ⑥The repeatability of myocardial work parameters was better in both groups. Conclusions:Myocardial work parameters obtained by PSL are early and sensitive parameters for evaluating left ventricular systolic function impairment in patients with hyperglycemia during pregnancy which can provide reliable and objective quantitative indicators for early clinical intervention and improvement of prognosis.
