Objective: To observe the clinical efficacy of Zhen'ai needling method in Nei Jing (Classic of Internal Medicine) for children with allergic rhinitis (AR) accompanied by adenoid hypertrophy (AH). Methods: A total of 74 children who met the screening criteria were divided into a Zhen'ai group and a control group by the random number table method, with 37 cases in each group. The control group was treated with acupuncture at Zusanli (ST 36), Hegu (LI 4), Yingxiang (LI 20), Juliao (ST 3), Yintang (GV 29), Shangxing (GV 23) and Baihui (GV 20). The Zhen'ai group added points of Zhen'ai needling method {Shanglianquan [Extra, located at 1 cun above Lianquan (CV 23)], Tianrong (SI 17) and Lieque (LU 7)} in addition to the points in the control group. The needles were retained for 30 min. The treatment was performed twice a week. The total nasal symptom score (TNSS), sino-nasal outcome test-20 (SNOT-20) and symptom scale for AH (SSAH) were assessed before and after 10 treatments. The clinical efficacy of the two groups was compared after treatment. Results: During the treatment, 5 cases dropped out in the control group and 2 cases in the Zhen'ai group. After treatment, the total effective rate of the Zhen'ai group was 94.3％, versus 93.8％ in the control group. There was no significant difference between the two groups (P>0.05). The markedly effective rate of the Zhen'ai group was 42.9％, versus 12.5％ in the control group, and the difference was statistically significant (P<0.05). After treatment, there were significant intra-group differences in the scores of TNSS, SNOT-20 and SSAH in both groups (all P<0.05); the scores of SNOT-20 and SSAH in the Zhen'ai group were lower than those in the control group, and the differences between the groups were statistically significant (both P<0.05). Conclusion: Both conventional acupuncture and conventional acupuncture plus Zhen'ai needling method can improve clinical symptoms of children with AR accompanied by AH; and conventional acupuncture plus Zhen'ai needling method has a better effect than conventional acupuncture in improving AH symptoms.

OBJECTIVETo study the influence of cow's milk protein allergy (CMPA) on the diagnosis of functional gastrointestinal diseases (FGID) based on the Rome IV standard in infants and young children.

METHODSA total of 84 children aged 1 month to 3 years who were diagnosed with CMPA were enrolled as the case group, and 84 infants and young children who underwent physical examination and had no CMPA were enrolled as the control group. The pediatricians specializing in gastroenterology asked parents using a questionnaire for the diagnosis of FGID based on the Rome IV standard to assess clinical symptoms and to diagnose FGID.

RESULTSThe case group had a significantly higher incidence rate of a family history of allergies than the control group (P<0.05). In the case group, 38 (45%) met the Rome IV standard for the diagnosis of FGID, while in the control group, 13 (15%) met this standard (P<0.05). According to the Rome IV standard for FGID, the case group had significantly higher diagnostic rates of reflex, functional diarrhea, difficult defecation, and functional constipation than the control group (P<0.05). The children who were diagnosed with FIGD in the control group were given conventional treatment, and those in the case group were asked to avoid the intake of cow's milk protein in addition to the conventional treatment. After 3 months of treatment, the case group had a significantly higher response rate to the treatment than the control group (P<0.05).

CONCLUSIONSIn infants and young children, CMPA has great influence on the diagnosis of FGID based on the Rome IV standard. The possibility of CMPA should be considered during the diagnosis of FGID.

Objective To investigate the epidemioiogical pattern of Borna disease virus (BDV) among different canine breeds in Ili, China, and to analyze its potential phylogeny. Methods BDV p24 RNA fragments were detected from peripheral blood mononuclear cells (PBMCs) of canine by modified nested RT-PCR (nRT-PCR). Possible false positives were excluded by determination of both BDV p40 RNA fragments and PMD19 plasmid standards. Analysis were performed on genetic sequence, homologous comparison, amino acid sequence and phylogeny after p24 positive products were validated. Results BDV p24 RNA fragments were found only in Kazakh Tobet (a shepherd dog) in 8 breeds of 150 cases and their overall positive rate was 11.0% (10/91). Compared with the strain of He/80 from horse and that of S6 from sheep in Germany, the homologous similarities of Kazakh Tobet was 99.2% and 95.7%, and that of amino acid as 100% and 89.3%, respectively. The kinship of Kazakh Tobet was close to He/80 and next to S6. Conclusion There was potential natural BDV infection in Kazakh Tobet in Ili, and its endemic strain was concerned with He/ 80 infecting Ili horse and S6 of German Merino sheep introduced into the region from Germany.

OBJECTIVETo evaluate the effectiveness and safety of β-elemene Injection as an adjunctive treatment for lung cancer by systematic review.

METHODSWe retrieved randomized controlled clinical trials related to the use of β-elemene Injection as an adjunctive treatment for lung cancer from Chinese Biomedical (CBMweb), Chinese Medical Current Content (CMCC), China National Knowledge Infrastructure (CNKI), ChinaInfo, Cochrane Central Register of Controlled Trials; MEDLINE, EMBASE, OVID and TCMLARS. We also referred to an unpublished conference proceeding titled Clinical Use and Basic: Elemene Injection. We then divided the studies into non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) subgroups by RevMan 5.1 software.

RESULTSA total of 21 source documents (1,467 patients) matched pre-specified criteria for determining the effectiveness and safety of β-elemene Injection as an adjunctive treatment for lung cancer. Five studies involving 285 NSCLC patients reported a higher 24-month survival rate (39.09%) with the adjunctive treatment than with chemotherapy alone (26.17%; RR, 1.51; 95% CI, 1.03 to 2.21). Four studies involving 445 patients reported that the increased probability for improved performance status for patients treated with elemene-based combinations was higher than that of patients treated with chemotherapy alone (RR, 1.82; 95% CI, 1.45 to 2.29). The results from a subgroup analysis on 12 studies involving 974 NSCLC patients and 9 studies involving 593 patients with both SCLC and NSCLC showed that the tumor control rate for NSCLC improved more in the elemene-based combinations treatment group (78.70%) than in the chemotherapy alone control group (71.31%; RR, 1.06; 95% CI, 1.00 to 1.12). The tumor response rate for NSCLC also improved more among patients treated with elemenebased combinations (50.71%) than among patients treated with chemotherapy alone (38.04%; RR, 1.34; 95%CI, 1.17 to 1.54). In addition, the main adverse reaction to β-elemene Injection was phlebitis, but usually only to a mild degree. An Egger's test showed no publication bias in our study (P=0.7030).

CONCLUSIONSThe effectiveness of chemotherapy for the treatment of lung cancer may improve when combined with β-elemene injection as an adjunctive treatment. The combined treatment can result in an improved quality of life and prolonged survival. However, these results require confirmation by rigorously controlled trials.

Objective To investigate the epidemiological pattern of Borna disease virus (BDV)infection in horses and to analyze the phylogenetic tree of derived BDV in Yili, Xinjiang. Methods We established a modified nested RT-PCR (nRT-PCR) to detect BDV p24 segment in peripheral blood mononuclear cells (PBMCs) and brain tissues of 120 horses in Yili, Xinjiang. Positive products were analyzed by sequencing and homology analysis. Results The positive rate of BDV infection was 2.5% in both PMBCs and brain tissues at the same time. The gene sequence revealed in positive PCR samples was more than 93 % ,identical to that of BDV derived from horses in other countries. We also noticed a high degree of identity ( >98 % ) to standard strain He/80 in gene sequence of positive PCR samples. Conclusion Our study found the presence of BDV natural infection in horses in Yili. The endemic BDV had a high degree of identity to standard strain He/80.

Objective To study the first locally identifcd A/HINI secondary cases outbreak in China. Methods Interview and field investigation were integrated to describe the whole process of transmission on each case and to illustrate the relationships between the onset of the disease and the retated factors. Results Two contact persons appearanced fever and whose throat swabs were tested positive to H1N1 viral nucleic acid. The two had a history of contact in a short distance with the initial imported case without any protective measure in the poor air ventilation. The patients clinical situation was slight. The incubation was between 37 hours and 57 hours. No other new case was found after intervention as isolation and antisepsis were taken. Conclusion This event was proved to be an outbreak of local A/H1N1 secondary cases caused by the imported case. The main mode of transmission was personal contact in a short distance without protection, through air and droplet. The locus with poor air ventilation was high risk place. Contact persons should be observed seven days and tested continuously.Infectivity and pathogenicity of the A/H1N1 virus were limited and appeared weakened by generations. Patient's condition was related with persistence and frequency of contact with the infection sources. Enhancing management of contact persons, health education, early diagnose, early treatment and early insulation were effective measures of controling and prenventing the spread A/H1N1.

Objective To screen the MYBPC3 gene mutations in Han Chinese patients with hypertrophic cardiomyopathy ( HCM ). Methods Sixty-six patients with HCM were enrolled for the study. The exons in the functional regions of MYBPC3 were amplified with PCR and the products were sequenced. Results Four novel mutations and four common polymorphisms were identified in this patient cohort. A Lys301fs mutation in exon10 was evidenced in a H30, and when he was 47 years old, he had the chest tightness, shortness of breath with septal hypertrophy of 18. 7mm; a Asp463stop mutation in exonl7 was detected in a H48, he was 24 years old 24-year-old when a medical examination showed ventricular septal hypertrophy of 15.4 mm; both Gly523Arg mutation in exonl8 and Tyr847His mutation in exon26 were found in a H53 with onset age 36 years old, feeling chest tightness after excise and his ventricular septal hypertrophy was 27 mm that time. MYBPC3 mutatons occurred in 4. 5% patients in this cohort. These mutations were not found in 100 non-HCM control patients. Conclusion MYBPC3 mutation is presented in a small portion of Han Chinese patients with HCM.

KangFuXinYe (KFX), the ethanol extract of the dried whole body of Periplaneta americana, is a well-known important Chinese medicine preparation that has been used to treat digestive diseases such as gastric ulcers for many years in China. However, its therapeutic effect and mechanism are not yet well understood. Thus, the aim of this study was to investigate the gastro-protective effects of KangFuXinYe (KFX) in indomethacin-induced gastric damage. Rats were randomly divided into six groups as follows: control, treated with indomethacin (35 mg·kg), different dosages of KFX (2.57, 5.14 and 10.28 mL·kg, respectively) plus indomethacin, and sucralfate (1.71 mL·kg) plus indomethacin. After treatment, rat serum, stomach and gastric homogenates were collected for biochemical tests and examination of histopathology firstly. Rat serum was further used for metabolomics analysis to research possible mechanisms. Our results showed that KFX treatment alleviated indomethacin-induced histopathologic damage in rat gastric mucosa. Meanwhile, its treatment significantly increased cyclooxygenase-1 (COX-1), prostaglandin E (PGE) and epidermal growth factor (EGF) levels in rat serum and gastric mucosa. Moreover, KFX decreased cyclooxygenase-2 (COX-2) and interleukin-6 (IL-6) levels. Nine metabolites were identified which intensities significantly changed in gastric damage rats, including 5-hydroxyindoleacetic acid, indoxylsulfuric acid, indolelactic acid, 4-hydroxyindole, pantothenic acid, isobutyryl carnitine, 3-methyl-2-oxovaleric acid, sphingosine 1-phosphate, and indometacin. These metabolic deviations came to closer to normal levels after KFX intervention. The results indicate that KFX (10.28 mL·kg) exerts protective effects on indomethacin-induced gastric damage by possible mechanisms of action (regulating tryptophan metabolism, protecting the mitochondria, and adjusting lipid metabolism, and reducing excessive indomethacin).
