OBJECTIVETo investigate the regulation trend of Jinxin Oral Liquid (JXOL) on the expression of negative regulatory factor of TLR3 signaling pathway SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points.

METHODSTotally 75 BALB/c mice were randomly divided into 5 groups, i.e., the normal control group, the model group, the ribavirin group, the high dose JXOL group, and the equivalent dose JXOL group, 15 in each group. Each group had 3 intervention ways (I, II, and III) with 5 mice treated in each group. BALB/c mice were nasally infected with respiratory syncytial virus (RSV), and treated by different intervention ways. After intervention, mice were killed and their lung tissues were sampled, mRNA expression levels of RSV-M, SOCS1, and IFN-β were detected by Real time PCR. The expression of SOCSl at the protein level was detected by Western blot.

RESULTSCompared with the normal control group, the mRNA expression level of SOCS1 and IFN-β, and the protein expression level of SOCS1 increased significantly in the model group intervened by intervention I and II (all P < 0.01), but the mRNA expression level of IFN-β decreased significantly in model group intervened by intervention III (P < 0.01). Compared with the model group, the mRNA expression level of RSV-M all significantly decreased in the high dose JXOL group and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and III and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of IFN-β significantly decreased in the high dose JXOL group intervened by intervention I and II and the equivalent dose JXOL group intervened by intervention I (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III and the equivalent dose JXOL group intervened by intervention III (all P < 0.01). The protein expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III (all P < 0.01). Compared with the high dose JXOL group, the mRNA expression level of RSV-M decreased significantly in the equivalent dose JXOL group intervened by intervention I and II (P < 0.01). The mRNA expression level of SOCS1 and IFN-β decreased significantly in the equivalent dose JXOL group intervened by intervention I (P < 0.01), but the mRNA expression level of IFN-β increased significantly in the equivalent dose JXOL group intervened by intervention II and III (all P < 0.01). The protein expression level of SOCS1 decreased significantly in the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01).

CONCLUSIONSJXOL could inhibit the expression of SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points. Its regulatory effect might be associated with promoting the expression of interferon type I and further fighting against RSV.

OBJECTIVETo evaluate the effects of the Chinese herbal formula Wuzi Yanzong Pill (, WYP) on the spermatogenesis and specific secretory functions of Sertoli cells in rat model and to investigate the underlying mechanism.

METHODSFive groups of male Sprague-Dawley rats including the control group, the model group, the low-dose WYP group, the medium-dose WYP group and the high-dose WYP group (5 in each group) were treated daily with vehicle, multiglycosides of Tripterygium wilfordii Hook f (GTW) either alone (20 mg/kg) or followed by WYP (0.5, 1.0, or 2.0 g/kg daily), respectively for 30 days. Serum levels of follicle-stimulating hormone (FSH), inhibin B (INHB) and testosterone (T) were evaluated using enzyme-linked immunosorbent assay. Androgen-binding protein (ABP) gene expression and transferrin (TF) protein expression in testis tissue specimens of all rats were determined using real-time reverse transcriptase polymerase chain reaction and Western blotting analysis, respectively. Histopathological alterations in the testis were determined using Johnsen's score.

RESULTSThe toxicity of GTW towards Sertoli cell secretory functions and spermatogenesis was accompanied by increased serum FSH concentrations and decreased INHB and T concentrations. Upregulated ABP mRNA levels, and decreased TF protein expression and Johnsen's scores were detected in the model group compared with the control group P<0.05 or P<0.01). Oral high-dose WYP administrations to GTW-treated rats effectively alleviated all of the GTW-induced changes in specific secretory functions of Sertoli cells (ABP, INHB and TF). Furthermore, serum T level and Johnsen's score of the testis increased greatly compared with the model group (P<0.01).

CONCLUSIONWYP has the ability to improve the spermatogenesis, possibly through modulating the secretory proteins expression of Sertoli cells.

OBJECTIVETo investigate the effect of respiratory syncytial virus (RSV)-related pulmonary infection on endogenous metabolites in large intestinal mucosa in BALB/c mice using metabolomics technology based on gas chromatography-mass spectrometry (GC-MS).

METHODSMice were randomly divided into a control group and a RSV pneumonia model group (n=16 each). The mouse model of RSV pneumonia was established using intranasal RSV infection (100×TCID, 50 μL/mouse, once a day). After 7 days of intranasal RSV infection, the mice were sacrificed and GC-MS was used to identify endogenous metabolites and measure the changes in their relative content in colon tissue. SMCA-P12.0 software was used to perform principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) for endogenous metabolites in colon tissue. The differentially expressed metabolites in colon tissue were imported into the metabolic pathway platform Metaboanalyst to analyze related metabolic pathways.

RESULTSPCA and OPLS-DA showed significant differences between the control and RSV pneumonia model groups. A total of 32 metabolites were identified in the colon tissue of the mice with RSV pneumonia. The RSV pneumonia model group had significant increases in the content of leucine, isoleucine, glycine, alanine, arachidonic acid, and lactic acid, which were related to the valine, leucine, isoleucine, arachidonic acid, and pyruvic acid metabolic pathways.

CONCLUSIONSRSV pneumonia might cause metabolic disorders in the large intestinal tissue in mice.

OBJECTIVETo evaluate the therapeutic effect of laparoendoscopic single-site surgery (LESS) for treatment of male pseudohermaphroditism.

METHODSA 17-year-old patient with male pseudohermaphroditism and a female social sex was admitted. According to the request by the patient and the relatives for a female gender, LESS vaginoplasty and cryptorchidectomy were performed using a single multilumen port inserted through a 2.5 cm incision below the umbilicus, followed by reconstruction of the perineal region by open surgery.

RESULTSThe total operative time was 7 h, and the LESS procedure lasted for about 3.5 h. No other port incision was needed. The estimated intraoperative blood loss was 400 ml. No electrolyte or metabolic acid-base balance disorders were observed perioperatively. In the follow-up examination at 6 months after the operation, the reconstructed vagina healed smoothly without obvious contraction or fixation failure, and the perineal region showed good appearance.

CONCLUSIONWith minimal invasiveness, LESS surgery produces good cosmetic effect and allows rapid postoperative recovery, thus may become a promising alternative to the management of pseudohermaphroditism.
