Objective To study the therapeutic effect of Xuefu Zhuyu Capsule combined with sacubitril valsartan on dilated cardiomyopathy.Methods A total of 70 patients with dilated cardiomyopathy who were hospitalized in the Hospital from January to December 2020 were selected as the research objects and random-ly divided into control group and experimental group,with 35 cases in each group.The control group was only treated with sacubitril valsartan,and the experimental group was treated with Xuefu Zhuyu Capsule combined with sacubitril valsartan.According to the patient's blood pressure and renal function,sacubitril valsartan was titrated from a small dose to the maximum dose.Xuefu Zhuyu Capsule was uesd 2.4 g each time,twice a day,and the treatment time was three months.The symptoms of heart failure,glycosylated hemoglobin(HbA1c),low density lipoprotein(LDL),total cholesterol(TC),triglyceride(TG),ALT,AST,N-terminal pro-brain natriuretic peptide(NT-proBNP),left ventricular end-systolic diameter(LVEDd),left ventricular end-dias-tolic diameter(LVEDs),ejection fraction(EF)and the incidence of arrhythmia were observed in the two groups after treatment.Results After treatment,the level of NT-proBNP in the experimental group was sig-nificantly lower than that in the control group(P＜0.05).There was no significant difference in LDL,TC,TG,LVEDd,LVEDs and EF between the two groups(P＞0.05).The incidence of atrial tachycardia and ven-tricular premature beat in the experimental group was higher than that in the control group(P＜0.05).Con-clusion Xuefu Zhuyu Capsule combined with sacubitril valsartan can significantly improve the symptoms of patients with heart failure and reduce the level of NT-proBNP,but it may increase the proportion of patients with atrial tachycardia and ventricular premature beats.

Developmental coordination disorder (DCD) is a neurodevelopmental disorder with high incidence, low diagnosis rate and early onset of symptoms, which hinders the development of physical and mental health in children.Early identification and intervention of DCD can help reduce the lifelong adverse effects of the disease.However, general public in China still lacks awareness of this condition,and healthcare workers do not pay enough attention to the early screening and intervention of DCD.This paper summarizes the clinical characteristics, early screening and diagnosis of DCD, and expounds the clinical treatment of DCD from the two aspects of western and Chinese medicine intervention, and proposes the intervention treatment of integrated Chinese and western medicine for the first time, hoping to promote the development of early screening work, provide a new method for the research and development of DCD intervention in China, and improve the effectiveness of treatment.

OBJECTIVE：To establish a method for the determination of pyrrotinib concentration in plasma ，and apply it in clinic. METHODS ：After precipitated with methanol ，the plasma sample was determined by LC-MS/MS using imatinib as internal standard. The determination was performed on Ultimate AQ-C 18 column with mobile phase consisted of methanol （containing 0.1％ formic acid ）and water （containing 0.1％ formic acid ）（gradient elution ）at the flow rate of 0.4 mL/min. The column temperature was 40 ℃，and the sample size was 5 µL. The ion source was electrospray ionization source ，and the positive ion scanning was carried out in multiple reaction mode. The ion pairs for quantitative analysis were m/z 583.4→138.3（pyrrotinib）and m/z 494.5→ 393.4（internal standard ），respectively. Thirty breast cancer patients taking pyrrotinib were collected from the Affiliated Hospital of Qingdao University during Jun.-Nov. 2020 to determine their steady-state trough concentrations of pyrrotinib after a week of treatment. RESULTS ：The linear range of pyrrotinib were 5-300 ng/mL（r＝0.999 3）. The lower limit of quantification was 5 ng/mL. RSDs of intra-day and inter-day were not higher than 9.30％，and relative errors （REs）ranged －6.70％-5.04％. REs of stability tests were in the range of －1.92％-5.42％. The extraction method ，matrix effect and residual effect did not affect the quantitative analysis of the substance to be tested. The steady-state trough concentrations of pyrrotinib were 32.6-82.8 ng/mL，with an average plasma concentration of 53.8 ng/mL；there was about 2.54 fold individual difference. CONCLUSIONS ：Established LC-MS/MS method is simple ，sensitive and accurate ，and can be used for the plasma concentration monitoring of pyrrotinib in breast cancer patient.

Objective:To explore the possibility of hepatitis B core antibody (anti-HBc) in predicting hepatitis B virus surface antigen (HBsAg) clearance.Methods:Sixty cases with chronic hepatitis B who were previously treated with peginterferon α-2a combined with nucleos(t)ide analogues (NAs) antiviral therapy were divided according to the HBsAg clearance or non-clearance; 41 cases in the clearance group and 19 cases in the non-clearance group. Double antigen sandwich method was used to detect patients anti-HBc quantitative levels during the course of treatment and at baseline, 24, 48, 72 and 96 weeks. Logistic regression analysis and receiver operating characteristic curve (ROC) were used to evaluate the predictive ability of related influencing factors for HBsAg clearance.Results:With antiviral treatment prolongation, anti-HBC quantitative levels in the overall population showed a progressive downward trend in the clearance group and the non-clearance group, but the anti-HBC level in the clearance group was significantly higher than non-clearance group at the baseline and successive detection time points during the antiviral treatment ( P < 0.05). Multivariate logistic regression showed that baseline quantitative anti-HBC level, HBsAg decline at week 24 (log10 IU / ml), and alanine aminotransferase (ALT) > 1.5 times the upper limit of normal value (ULN) were all influencing factors for HBsAg clearance during the treatment ( OR = 0.156, P = 0.026; OR = 0.134, P = 0.023; OR = 0.239, P = 0.028). Among them, the baseline quantitative anti-HBc level was the best independent predictor for HBsAg clearance ( OR = 0.235; P = 0.004), and the sensitivity and specificity for predicting HBsAg clearance at > 3.40 log10 IU/ mL were 56.1% and 89.5%, respectively. Logistic regression model was used as a reference to construct combined predictors in order to improve the prediction accuracy. Among them, the combined factor 3 had the highest predictive value (the area under the ROC curve had reached up to 0.870; 95%CI was 0.781 ~ 0.960; P < 0.001). The cut-off value of combined factor 3 was > 0.386, and the sensitivity and specificity were 80.5% and 78.9%, respectively. In addition, the combined index had further improved the predictive value, which is the combination of any two or more indexes based on the baseline quantitative anti-HBC level, and HBsAg clearance predictive rate had reached 94.12% ~ 100%. Conclusion:The baseline quantitative anti-HBC level has the highest predictive value for HBsAg clearance. The combination of ALT > 1.5×ULN and HBsAg decline at 24 weeks during the treatment can more precisely predict HBsAg clearance. Therefore, it is a reliable non-invasive biomarker.

The current outpatient payment method based on fee-for-service induced serious demand, which increased the waste of medical insurance fund. The authors briefly introduced ambulatory patient groups(APG)with the same concept of diagnosis-related groups. According to the current situation of outpatient medical insurance payment and the degree of informatization in China, suggestions are put forward: launch a pilot project first and starting with chronic disease to promote reform; improve the quality of outpatient electronic medical records, and develop APG suitable for China; under the background of aging, cooperate with the total budget to ensure the security of medical insurance.

Preventive treatment of diseases is a traditional Chinese medicine (TCM) concept that conforms to the demand of modern healthcare emphasizing prevention. This concept, however, calls for close and orderly collaboration between general hospitals and primary community healthcare institutions, in order to encourage coordinated regional development. The authors described the new healthcare mode of " One Center, One Platform, and One Network" jointly built and run by Dongguan Municipal Health Bureau and Dongguan TCM Hospital. This practice has pioneered a full-range, closed-loop and one-stop service chain featuring preventive treatment. Such an innovative TCM health management system has realized information interconnection of preventive treatment, and upgraded the capacity and effectiveness of community medical services, hence expanding the number of beneficiaries.

Objective: To observe the changes of liver function, virology and serology and the safety of drug withdrawal in pregnant women who are chronic hepatitis B virus (HBV) carriers. Methods: A prospective clinical cohort was established to enroll pregnant women who are chronic HBV carriers and they were divided into the nucleoside/nucleotide analogs (NAs) intervention group and the non-NAs intervention group according to patients' wishes. Liver function, HBV DNA and HBV serological markers were detected at gestation, postpartum 6 weeks, 12 weeks, 24 weeks, 36 weeks and 48 weeks. Results: 351 patients were enrolled, 320 in the NAs intervention group and 31 in the non-NAs intervention group. The proportion of postpartum hepatitis flares in both groups was higher than that in pregnancy (39.4% vs 12.5%, P < 0.001; 38.7% vs 3.2%, P = 0.001). Six weeks postpartum was the peak period of hepatitis flares, and 96.0% (121/126) of the hepatitis flares occurred within 24 weeks postpartum. At 6 weeks postpartum, there were 6 cases of alanine aminotransferase (ALT) ≥ 10 times upper limit of normal (ULN) in the NAs intervention group. The rate of the hepatitis flare after drug withdrawal was 16.7% (34/203). Conclusion Regardless of the presence or absence of NAs intervention, pregnant women who are chronic HBV carriers have a certain proportion of hepatitis flares during pregnancy and postpartum, and the hepatitis flare even have a tendency to be severe. Therefore, drug withdrawal after delivery is not always safe, which requires close observation and classification. At 6 weeks postpartum, the incidence of hepatitis flares was high, and those who meet the treatment indications can get better therapeutic effects if given appropriate treatment. The vast majority (96%) of postpartum hepatitis flares occur within 24 weeks, so it is recommended to follow up to at least 24 weeks postpartum after discontinuation.

OBJECTIVE： To study the effects of Wuzhi soft capsule and imatinib mesylate tablet on the pharmacokinetics of imatinib in rats. METHODS： The rats were divided into single administration group and consecutive administration group. The single administration group was divided into imatinib group one （ig administration of blank soybean oil+imatinib suspension 10   mg/kg）， low-dose， medium-dose and high-dose of Wuzhi soft capsule+imatinib group （ig administration of Wuzhi soft capsule solution 134， 268， 536 mg/kg+imatinib suspension 10 mg/kg）， with 6 rats in each group. Each group was given imatinib suspension intragastrically 30 min after intragastric administration of blank soybean oil/Wuzhi soft capsule solution. The consecutive administration group was divided into imatinib group two （ig administration of blank soybean oil+imatinib suspension 10 mg/kg）， Wuzhi soft capsule low-dose+imatinib group （ig administration of Wuzhi soft capsule solution 134 mg/kg+imatinib suspension 10 mg/kg）， with 6 rats in each group. Each group was given blank soybean oil/Wuzhi soft capsule solution intragastrically for consecutive 14 d， once a day； 30 min after last administration， ig imatinib suspension. About 100 μL blood was collected before imatinib， 0.5， 1， 2， 2.5， 3， 4， 5， 6， 8， 12， 24 and 36 h after medication. The plasma concentration of imatinib was determined by HPLC-MS/MS. The pharmacokinetic parameters were fitted by using DAS 2.0 software. RESULTS： After single administration， compared with imatinib group one， cmax， t1/2， AUC0-36 h and AUMC0-36 h in low-dose， medium-dose and high-dose of Wuzhi soft capsule+imatinib group were increased significantly （P＜0.05 or P＜0.01）. After consecutive administration， compared with imatinib group two， cmax， t1/2 and AUMC0-36 h of imatinib+low-dose of Wuzhi soft capsule group were increased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS： Single administration and consecutive administration of Wuzhi soft capsule influence the pharmacokinetics of imatinib， increase plasma concentration of imatinib and prolong half-time.

OBJECTIVETo explore the repair effects of acupuncture for promoting the governor vessel and tranquilizing the mind (acupuncture technique) on cerebral white matter injury of premature infants.

METHODSA total of 56 cases of cerebral whiter matter injury of premature infants, the fetal age less than 35 weeks were selected and randomized into an observation group (27 cases) and a control group (29 cases). The routine basic rehabilitation therapy was used in the two groups. Additionally, in the observation group, the acupuncture technique was added, once a day and the treatment for 15 days was as 1 course. Totally, 3 courses of treatment were required. Before and after treatment, the cranial magnetic resonance imaging (MRI) and the diffusion tensor imaging (DTI) were adopted to observe the location and severity of cerebral white matter injury. The Gesell developmental scale was used to assess the nerve motor development.

RESULTSAfter treatment, the difference was not significant statistically in the severity of cerebral white matter injury in the infants between the two groups (>0.05). The FA value of cerebral white matter in the interesting zone was increased as compared with that before treatment in the infants of the two groups (both<0.05). The result in the observation group was higher than that in the control groups (<0.05). After treatment, DQ value of each function zone in Gesell scale was all increased as compared with that before treatment in the two groups (all<0.05). After treatment, the DQ values of gross motor, fine motor and social adaptability in the observation group were higher than those in the control group (all<0.05). After treatment, the difference was not significant in DQ value of individual-social and speech behaviors between the two groups (both>0.05).

CONCLUSIONAcupuncture technique for promoting the governor vessel and tranquilizing the mind promotes the repair of the function in the premature infants with cerebral white matter injury and further benefits the promotion of the intelligence.

OBJECTIVETo observe the effects of acupuncture at different acupoints in meridians and meridians on lower limb muscle tension in children with spastic cerebral palsy.

METHODSNinety children with spastic cerebral palsy aged between 2 to 6 years old were divided into a yin-meridian group, a yang-meridian group and a rehabilitation group, 30 cases in each one. The patients in the rehabilitation group were treated with routine rehabilitation treatment; the patients in the yin-meridian group were treated with routine rehabilitation treatment and acupuncture at Xuehai (SP 10), Yinlingquan (SP 9), Sanyinjiao (SP 6), Taixi (KI 3) and Taichong (LR 3) along meridians; the patients in the yang-meridian group were treated with routine rehabilitation treatment and acupuncture at Futu (ST 32), Zusanli (ST 36), Yanglingquan (GB 34), Guangming (GB 37) and Xuanzhong (GB 39) along meridians. All the three groups were treated once each other day, 10 times as one course, and totally 20-day treatment was given. Before and after treatment, modified Ashworth scale (MAS), clinical spasm index (CSI) and integrated electromyography (iEMG) of surface electromyogram of gastrocnemius muscle were evaluated.

RESULTSCompared before treatment, the MAS and CSI in the yin-meridian group and yang-meridian group were improved after treatment (<0.05, <0.01); the differences before and after treatment in the rehabilitation group were not significant (both >0.05). After treatment, the differences between the rehabilitation group and yin-meridian group, yang-meridian group were significant (<0.05, <0.01); the differences of MAS and CSI between the yin-meridian group and yang-meridian group were not significant (both >0.05). Compared before the treatment, the right-side iEMG and left-side iEMG were reduced in the yin-meridian group and yang-meridian group (all <0.05); the right-side iEMG was increased in the rehabilitation group (<0.05). After treatment, the iEMG in the yin-meridian group and yang-meridian group were lower than that in the rehabilitation group (all <0.05); the differences of iEMG before and after treatment in the yin-meridian group and yang-meridian group were higher than that in the rehabilitation group (all <0.05); the differences of iEMG between the yin-meridian group and yang-meridian group were not significant (both >0.05).

CONCLUSIONAcupuncture at meridians and meridians could reduce muscle tension of lower limb and improve limb spasticity in children with spastic cerebral palsy, and the two acupuncture methods have similar clinical curative effect.
