Forty batches of Lonicerae Japonica Fse i collected extensively and prepared as the test solution. Their chromatographic fingerprints and anti-influenza virus IC50 value (half maximal inhibitory concentration) were determined respectively. Then Unscrambler software was used, and spectrum-efficient correlation analysis was done for chromatographic fingerprints data and IC50 data by partial least squares regression method, to establish spectrum-efficient correlation model for anti-influenza virus of Lonicerae Japonicae Flos. Then the other 10 batches of Lonicerae Japonicae Flos were used to verify the model and explore the adaptability of this spectrum-efficient correlation model based on partial least squares regression method. The mathematical model obtained R2 of 0.969489 and RM-SEC of 0.070691 for calibration set; R2 of 0.959042 and RMSECV of 0.084005 for cross validation set. The verification experiment results showed that the relative error between the predicted values and measured values was within 10% in all 10 hatches, and within 5% in 80% of them. The results showed that the established spectrum-efficient correlation model could be used to evaluate the biological activity of anti-influenza virus of Lonicerae Japonicae Flos by determining its HPLC fingerprints.

Near infrared (NIR) spectroscopy as a kind of rapid process analysis technology has been successfully applied in Chinese medicine pharmaceutical process. In this research, the technology was adopted to establish the rapid quantitative analysis models of main indicators from the Lonicera japonica and Artemisia annua alcohol precipitation process of Reduning injection. On-line NIR spectra of 142 samples from alcohol precipitation process were collected and the content of main indicators for each sample were detected through off-line HPLC. With eliminating outliers, determination of spectra pretreatment method and selecting optimal band, the NIR quantitative calibration model for each indicator was established using partial least squares (PLS). These models were used to predict the unknown samples from precipitation process of Reduning injection to achieve the goal of rapid detection. The results showed that the models were ideal. The correlation coefficients of models for neochlorogenic acid, chlorogenic acid, 4-O-caffeoylquinic acid and secoxyloganin were 0.973 872, 0.985 449, 0.975 509 and 0.979 790, respectively and their relative standard errors of prediction (RSEP) were 2.922 49%, 2.341 37%, 2.930 40% and 2.184 60%, respectively. This study indicated that the NIR quantitative calibration model showed good stability and precision, and it can be used in rapid quantitative detection of main indicators of efficacy in order to on-line monitor the alcohol precipitation process of Reduning injection.

Objective: To observe the difference in clinical efficacy between acupuncture with point selection based on syndrome differentiation along the meridians and acupuncture at non-meridian and non-acupoint points for functional dyspepsia (FD). Methods: A total of 74 FD patients were randomized into an observation group and a control group, with 37 cases in each group. Both groups received acupuncture treatment. Zusanli (ST 36) and Neiguan (PC 6) were selected in the observation group, with Taichong (LR 3) and Neiting (ST 44) added for excess syndrome, and Gongsun (SP 4) and Yinlingquan (SP 9) added for deficiency syndrome. Four non-meridian and non-acupoint points were selected in the control group. The treatments in both groups were performed once a day with a 2-day break after 5 consecutive treatments, which constituted one treatment course. A total of 4 courses were performed. The scores of Nepean dyspepsia index (NDI) and Leeds dyspepsia questionnaire (LDQ) were recorded before and after treatment, and during follow-up (8, 12, 16, 20 and 24 weeks after recruitment) to assess the clinical efficacy. Results: The NDI scores in the two groups after treatment and at each time point during follow-up were higher than those before treatment (all P<0.05), and the LDQ scores were lower than those before treatment (all P<0.05). The NDI scores after treatment and at each time point during follow-up in the observation group were higher than those in the control group (all P<0.01); the total LDQ score and scores of upper abdominal pain, postprandial satiety and upper abdominal burning sensation after treatment and at each time point during follow-up in the observation group were significantly lower than those in the control group (P<0.01 or P<0.05).. Conclusion: Acupuncture with point selection based on syndrome differentiation along the meridians has a better curative effect than acupuncture at non meridian and non-acupoint points in the treatment of FD.

Objective To observe the effect of two kinds of Kinesio taping methods on shoulder pain in hemiplegic patients with stroke during spasm period. Methods From October,2015 to September,2017,75 stroke hemiplegic patients with shoulder pain during spasm period were randomly divided into group A(n=25),group B(n=25)and control group(n=25).Three groups were given conventional treatment,and group A and group B received two kinds of Kinesio taping methods,respectively.Be-fore and four weeks after treatment,the shoulder pain was assessed with Visual Analogue Scale(VAS),the motor function of upper limb was assessed with Fugl-Meyer Assessment(FMA),and their activities of daily living was assessed with modified Barthel Index(MBI).

Conclusion Kinesio taping combined with rehabilitation training for the treatment of stroke patients following hemiple-gia during spasm period can relieve the shoulder pain and improve the motor function of upper limb and activi-ties of daily living.The curative effect varies with different taping methods.

OBJECTIVETo study the influence of acute pancreatitis in pregnancy (APIP) on pregnancy outcomes and neonates.

METHODSA retrospective analysis was performed for 33 APIP patients and 31 neonates born alive.

RESULTSOf the 33 APIP patients, 26 (79%) developed APIP in the late pregnancy. Fourteen (45%) patients had hyperlipidemic APIP, 13 (42%) had biliary APIP, and 4 (13%) had other types of APIP. According to the severity, 22 (67%) were mild APIP, 5 (15%) were moderate APIP, and 6 were severe APIP. None of the 33 APIP patients died. Among the 20 patients with term delivery, 11 underwent termination of pregnancy; among the 10 patients with preterm delivery, 9 underwent termination of pregnancy; two patients experienced intrauterine fetal death, and one experienced abortion during the second trimester. Among the 31 neonates born alive (two of them were twins), 1 (3%) died, 12 (39%) experienced neonatal hyperbilirubinemia, 8 (26%) had neonatal hypoglycemia, 6 (19%) had neonatal respiratory distress syndrome, 5 (16%) experienced infectious diseases, and 2 (6%) experienced intracranial hemorrhage. The hyperlipidemic APIP group had a higher percentage of patients undergoing termination of pregnancy than the biliary APIP and other types of APIP groups (P<0.05). The incidence rate of preterm infants in the moderate APIP was higher than in the mild and severe APIP groups (P<0.05). The mean birth weights of neonates were the lowest in the moderate APIP group. The incidence rates of neonatal respiratory distress syndrome, intracranial hemorrhage, and infectious disease were the lowest in the mild APIP group (P<0.05).

CONCLUSIONSAPIP can lead to adverse pregnancy outcomes and neonatal diseases, which are associated with the severity of pancreatitis.

OBJECTIVETo study the function of the SP3111 protein in fertilization and early embryo development through in vitro fertilization (IVF) experiments following anti-SP111 antibody (Ab2438) blocking.

METHODSSperm samples collected from male mice were divided into an experimental, a blank control and a negative control group before IVF. The sperm of the experimental group was incubated with Ab2438 for 1 h followed by IVF and observed for the rates of fertilization and embryo fragmentation at 2, 4, 6, 8 and 22 h. Then the fertilized eggs were incubated with Ab2438, and the rates of fertilization embryo fragmentation were observed at 22 h.

RESULTSAfter the sperm was incubated with Ab2438, the incidences of embryo fragmentation were 5.26, 8.77, 23.25, 43.42 and 59.21% at 2, 4, 6, 8 and 22 h, respectively, with significant differences from the control groups (P < 0.01). After 22 h Ab2438 incubation of the fertilized eggs, the rates of normal and fragmented embryos of the experimental group were 23.64 and 63.64%, respectively, significantly different from those of the control groups (P < 0.01).

CONCLUSIONAnti-SP3111 antibodies remarkably affected fertilization and early embryo development in mice. The SP3111 protein may be a signal molecule and plays a role in fertilization and early embryo development together with other proteins. Further studies on the function of the SP3111 protein in reproduction may offer a new insight into the molecular mechanism of infertility.

Objective: To investigate the spectrum of gene mutations in adult patients with B-acute lymphoblastic leukemia (B-ALL), and to analyze the influences of different gene mutations on prognosis. Methods: DNA samples from 113 adult B-ALL patients who administered from June 2009 to September 2015 were collected. Target-specific next generation sequencing (NGS) approach was used to analyze the mutations of 112 genes (focused on the specific mutational hotspots) and all putative mutations were compared against multiple databases to calculate the frequency spectrum. The impact of gene mutation on the patients' overall survival (OS) and recurrence free survival (RFS) was analyzed by the putative mutations through Kaplan-Meier, and Cox regression methods. Results: Of the 113 patients, 103 (92.0%) harbored at least one mutation and 29 (25.6%) harbored more than 3 genes mutation. The five most frequently mutated genes in B-ALL are SF1, FAT1, MPL, PTPN11 and NRAS. Gene mutations are different between Ph⁺ B-ALL and Ph^- B-ALL patients. Ph^- B-ALL patients with JAK-STAT signal pathway related gene mutation, such as JAK1/JAK2 mutation showed a poor prognosis compared to the patients without mutation (OS: P=0.011, 0.001; RFS: P=0.014,<0.001). Patients with PTPN11 mutation showed better survival than those without mutation, but the difference was not statistically significant (P value > 0.05). Besides, in Ph⁺ B-ALL patients whose epigenetic modifications related signaling pathway genes were affected, they had a worse prognosis (OS: P=0.038; RFS: P=0.047). Conclusion: Gene mutations are common in adult ALL patients, a variety of signaling pathways are involved. The frequency and spectrum are varied in different types of B-ALL. JAK family gene mutation usually indicates poor prognosis. The co-occurrence of somatic mutations in adult B-ALL patients indicate the genetic complex and instability of adult B-ALL patients.
