Objective: To review the problems existing in the development and application of current electroacupuncture (EA) apparatuses, and provide reference for the development of EA apparatuses. Methods: Related literatures about EA apparatus were derived from China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang) and Chongqing VIP Database (CQVIP) between 2013 and 2017. Literatures about the development of EA apparatuses and the application for experimental research and clinical treatment published in Chinese journals were retrieved, and the development and application of EA apparatuses were summarized. Results: Among the 107 selected literatures, 48 types of EA apparatuses were used, of which only 11 models could be found in the registration list and within the validity period. There was no registration information for the EA apparatus newly developed in the past 5 years. The EA parameters used in experimental research and clinical treatment in Chinese medicine were different, and the combination of stimulation parameters was diverse. Conclusion: At present, most of the new EA products are still in the experimental or research stage, and the transformation of results has not yet been achieved. Moreover, there is no unified standard for the use of EA apparatus and its stimulation parameters in experimental research and clinical treatment, which is not conducive to the standardization process of EA stimulation.

In order to identify Cimicifugae Rhizoma from its adulterants and to ensure its safe use, the internal transcribed spacer 2 (ITS2) sequence of Cimicifugae Rhizoma and its adulterants were amplified and bidirectionally sequenced by DNA barcoding technology. Sequence assembly and consensus sequence generation were performed by the CodonCode Aligner V3.7.1. The genetic distances were computed by MEGA 5.0. Identification analyses were performed using neighbor-joining (NJ) methods. The length of ITS2 sequence of the three origin plants of Cimicifugae Rhizoma include Cimicifuga heracleifolia, C. foetida, C. dahurica was 217, 219 and 219 bp, respectively. Their intraspecific genetic distance was much lower than the interspecific genetic distance with their closely related species. The NJ tree of ITS2 indicated that the three origin plants of Cimicifugae Rhizoma formed a monophyletic clade, Cimicifugae Rhizoma and its adulterants could be distinguished clearly. The authors proposed that ITS2 sequence was suitable for the authentication of Cimicifugae Rhizoma and its adulterants.

OBJECTIVETo explore the relation of the anogenital distance (AGD) with cryptorchidism in male newborns.

METHODSThis study included 350 male infants delivered in two community hospitals between September 2013 and September 2014. Within 24 hours after birth, a pediatric surgeon measured the AGD of the neonates and determined whether they had cryptorchidism. According to the testicular position, we divided the undescended testes into three types: upper scrotal, inguinal, and non-palpable.

RESULTSTotally 39 cases of cryptorchidism were found in the 350 newborns. The AGD of the cryptorchidism infants was significantly shorter than that of the normal neonates ([2.01 ± 0.22] vs [2.35 ± 0.19] cm, P < 0.01), and statistically significant differences remained even when preterm and low birth-weight infants were excluded ([2.32 ± 0.14] vs [2.06 ± 0.19] cm; (2.37 ± 0.17) cm vs (2.12 ± 0.12) cm, all P < 0.01). The newborns with higher-position cryptorchidism had a shorter AGD, though with no significant difference (F = 0.434, P > 0.05). No significant differences were observed in the AGD between unilateral and bilateral cryptorchidism ([1.96 ± 0.13] vs [2.02 ± 0.17] cm, P > 0.05).

CONCLUSIONShorter AGD is associated with a higher incidence of cryptorchidism in male newborns. AGD could serve as a potential biomarker for disruption of androgen action during the male programming window period.

Objective To investigate the acute toxicity, subacute toxicity, nasal membrane local toxicity of the Magnolia biondii Pamp volatile oil nanometer bangosome. Methods Kunming mice and SD rats were selected as experimental material. Kunming mice were used in the acute and subacute toxicity tests by intragastric administration of Magnolia biondii Pamp volatile oil nanometer bangosome with different dosage and different time, and SD rats were used in the nasal membrane local toxicity test by nose dropping, while the control group was treated with intragastric administration of or nose dropping with normal saline for the same dosage. The treatment course lasted fifteen days. At the end of the tests, the general condition, routine blood test, function index of live and kidney, organ humid weight index, histological changes of liver and kidney and ultra microstructure change of rat nasal membrane were obtained and compared with the control group. Results In the acute toxicity test, the daily maximum tolerant dosage by intragastric administration was equal to 222.7 times of the clinical routine, with no marked toxic reaction. In the subacute toxicity test, the general condition, blood test, organ humid weight index and histological changes of live and kidney in different dosage groups were similar to the control group. While in the function index of live and kidney, uric acid was stepped down in the middle and large dose groups, and total bilirubin was decreased in the large dose group. The nasal membrane local toxicity test revealed that there was little change in the ultra microstructure of rat nasal membrane.Conclusion The Magnolia biondii Pamp volatile oil nanometer bangosome may have little toxicity by intragastric administration and nose dropping.

Objective To investigate the potential role of soluble triggering receptor expressed on ayeloid cells-1(sTREM-1) expression in serum,endotracheal aspiration (ETA),bronchoalveolar lavage fluid (BALF) and exhaled breath condensate (EBC) as early biomarkers for the diagnosis of ventilator-associated pneumonia (VAP) in patients with acute ischemic stroke.Methods One hundred and thirty-two patients with clinically suspected VAP were prospectively included in this multicenter study.The levels of sTREM-1 in serum,ETA,BALF and EBC were analyzed for diagnostic evaluation at the time of VAP clinically suspected.The bacterial count over 104/CFU as a gold standard for VAP,and the receiver operating characteristic curves were used to identify the ideal cutoff values.Results VAP was confirmed in 76 patients (57.58％).In VAP patients (VAP group) and non-VAP patients (non-VAP group),the level of sTREM-1 in BALF was 32.35 (30.08-41.72) and 18.92(11.89-31.72) ng/L,and the level of sTREM-1 in EBC was 1.57 (1.02-2.61) and 0.41(0.19-1.61)ng/L respectively.The level of sTREM-1 in BALF and in EBC in VAP group was significantly higher than that in non-VAP group (P ＜0.05).The optimum cutoff value for sTREM-1 in BALF according to the maximum Youden index was 23.61 ng/L.This cutoff value had 85.5％ sensitivity and 73.1％ specificity,with 0.813 area under the curve.sTREM-1 in BALF had excellent correlation with that in EBC (R2 =0.78,P ＜ 0.05).Conclusions The results of this prospective study suggest that sTREM-1 levels in BALF and EBC have better roles in facilitating the diagnosis of VAP and thus may be practically recommended to guide the administration of antibiotics when VAP is suspected.

Objective:To study the antitumor effect and mechanism of cocultured CIK cells modified with IL-24 gene and autologous DCs on HL-60 cells in vitro.Methods:DCs and CIK cells were prepared routinely from human peripheral blood mononuclear cells ( PBMC).IL-24 gene was transferred into CIK cells via electroporation.The cells obtained were named CIK-IL24.RT-PCR and ELISA were used to evaluate expression of IL-24 gene in transfected CIK cells.The phenotypic changes of CIK cells were identified by flowcytometry analysis.The concentration of IFN-γ and TNF-α in supernatant of CIK was determined by ELISA.FCM was used to determine the cytotoxicity of cocultured CIK cells modified with IL-24 gene and autologous DCs against HL-60 cells.Results:Eukaryotic expressing plasmid pcDNA3.0-IL24 was transferred into CIK cells successfully via electroporation.The expressing rate of CD3~+、CD3~+CD56~+ cells had no significant change in CIK cells.However,the rate of CD4~+CD25~+ cells was significantly decreased compared with that of the control group.Expression of adhesion molecules CD54,CXCR4 were significantly increased on CD3+CD56+ cells.CIK-IL24 cells produced markedly higher levels of IFN-γ and TNF-α as compared with the CIK cells.By comparison with non-transfected CIK cells co-cultured with DCs,transfected CIK cells co-cultured with DCs had a significantly higher lytic activity against HL-60 cells.Conclusion:IL-24 gene modification can enhance the anti-tumoral immunity of CIK cells,the mechanism of which might be related to the increased secretion of IFN-γ,TNF-α,up-regulation of adhesion molecule expression,and reduction of the rate of CD4~+CD25~+ cells in CIK cells.
