OBJECTIVETo observe the therapeutic effect of Qilin Pills combined with clomiphene on idiopathic oligoasthenospermia.

METHODSWe randomly assigned 300 patients with idiopathic oligoasthenospermia to a trial (n = 156) and a control group (n = 144) to be treated with Qilin Pills (6 g, tid) combined with clomiphene (50 mg, qd) and clomiphene alone (50 mg, qd), respectively, both for a course of 12 weeks. Before and after 4, 8, and 12 weeks of medication, we determined sperm concentration, the percentages of grade a and grade a + b sperm, sperm motility, and the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T), followed by evaluation of the clinical efficacy of Qilin Pills with the pregnancy rate in the patients' spouses as the secondaty therapeutic indexes.

RESULTSCompared with the baseline, both groups of patients showed remarkably improved semen parameters and hormone levels after treatment (all P < 0.01). After 4, 8, and 12 weeks of medication, statistically significant differences were observed between the trial and control groups in sperm concentration ([17.06 ± 2.24] vs [15.07 ± 2.48], [22.10 ± 2.65] vs [18.11 ± 2.97], and [28.13 ± 3.59] vs [21.21 ± 3.60] x 10(6)/mL, P < 0.01), the percentage of grade a sperm ([15.03 ± 2.39] vs [13.08 ± 2.51], [21.08 ± 3.16] vs [16.04 ± 3.05], and [28.08 ± 4.70] vs [20.14 ± 4.74]%, P < 0.01), the percentage of grade a + b sperm ([30.10 ± 5.07] vs [26.21 ± 3.96], [38.08 ± 5.64] vs [30.07 ± 4.80], and [48.04 ± 6.49] vs [35.28 ± 4.77]%, P < 0.01), sperm motility ([42.04 ± 4.86] vs [40.29 ± 4.19], [52.05 ± 5.58] vs [48.03 ± 4.40], and [65.03 ± 5.13] vs [56.67 ± 4.99]%), the FSH level ([7.75 ± 1.38] vs [7.20 ± 1.17], [10.83 ± 1.23] vs [9.10 ± 1.32], and [14.22 ± 0.84] vs [12.06 ± 1.45] IU/L, P < 0.01), the LH level ([10.05 ± 1.68] vs [9.18 ± 1.54], [13.96 ± 1.68] vs [11.99 ± 1.71], and [19.01 ± 2.42] vs [15.86 ± 2.08] IU/L, P < 0.01) and the T level ([19.19 ± 192] vs [18.34 ± 1.79] [21.06 ± 1.63] vs [20.06 ± 1.56], and [24.63 ± 1.06] vs [22.03 ± 1.49] nmol/L, P < 0.01). The pregnancy rate in the patients' spouses was significantly higher in the trial than in the control group at 4, 8, and 12 weeks (1.92 vs 0.69, 4.81 vs 3.47, and 11.54 vs 8.33%, P < 0.01). There were no statistically significant differences in drug tolerance between the two groups (P > 0.05). No obvious adverse reactions were observed.

CONCLUSIONQilin Pills combined with clomiphene can evidently improve the seminal quality and hormone level of oligoasthenospermia patients with no obvious adverse events. However, its long-term efficacy and tolerance deserve further clinical investigation.

OBJECTIVETo explore the invasiveness of papillary thyroid microcarcinoma(PTMC)with BRAF mutation.

METHODSTotally 99 patients with PTMC with BRAF mutation were enrolled in this study, meanwhile another 97 patients with papillary thyroid carcinoma (PTC) (tumor size>1 cm)with BRAF mutation were included as controls. The clinicopathologic factors including extrathyroidal invasion, multifocality, and distant metastasis were analyzed.

RESULTSThe rates of extrathyroidal invasion and nodal metastasis in PTMC group were as high as 16.10% and 71.74%, respectively. In the PTMC group and PTC group,the extrathyroidal invasion rate was 16.10% and 39.18%, cervical lymph node metastasis rate was 71.74% and 91.75%, and distant metastasis rate was 1.01% and 9.28%, respectively. In the PTMC subgroups with tumor sizes ≤0.3 cm, 0.3-0.6 cm, and 0.6-1.0 cm, the cervical lymph node invasion rate was 60.00%, 72.50%, and 73.81%, the extrathyroidal invasion rate was 10.00%, 9.09%, and 24.44%, and the multifocality rate was 60.00%, 38.64%, and 57.78%, respectively. Univariate analysis showed that the tumor size was not significantly correlated with multifocality (Χ (2)=3.752, P=0.153), cervical lymph node metastasis (Χ (2) = 0.780,P = 0.677), extrathyroidal invasion (Χ (2) = 4.182, P = 0.124), and distant metastasis (Χ (2)=1.212, P = 0.545). While the BRAF group and PTC group were not significantly different in multifocality (Χ (2) = 1.742, P=0.187), they were significantly different in terms of extrathyroidal invasion (Χ (2) = 13.000, P = 0.000), nodal involvement (Χ (2) = 12.819, P = 0.000), and distant metastasis (Χ (2) = 5.316, P = 0.021). Multivariate analysis showed that nodal metastasis was independently associated with size>1 cm (P=0.001) and extrathyroidal invasion (P=0.003).

CONCLUSIONSBRAF mutant PTMC manifests relative high extrathyroidal involvement and nodal metastasis, and the similar multifocality as BRAF mutant PTC. Radioactive iodine should be considered in PTMC with the presence of BRAF mutation combined with extrathyroidal invasion or nodal metastasis.

OBJECTIVETo explore the relationship between neuropeptide substance P (SP) and wound healing in scalded rats.

METHODS(1) Scalded rats with different degrees of scald injury were employed as the experimental model and were sacrificed at 24 post scald hour (PSH), and on 3, 7 and 14 post scald days (PSD). The SP content in the wound was detected with radioimmunoassay method. (2) The murine granulation tissue fibroblasts (GTF) were cultured with different culture media, and divided into control, SP and Spantide (SP receptor antagonism) groups. The effects of SP and Spantide on the cellular activity and apoptotic rate of murine GTF were assessed in vitro.

RESULTSThere was significant difference of the SP content among the superficial (145 +/- 78) ng/g, partial (94 +/- 48 ng/g) and full thickness (53 +/- 27 ng/g) scald wounds at 24 PSH (P < 0.01), while the SP content in partial thickness burn wound on 3 and 7 PSD obviously increased; and that in deep partial thickness burn wound obviously increased on 7 and 14 PSD. But the SP content remained unchanged in full thickness scald wound. (2) SP could promote the activity of GTF and inhibit its apoptosis (The GTF activity in control, SP groups were 0.21 +/- 0.05, 0.36 +/- 0.07, respectively, P < 0.01). Spantide could inhibit the interaction between SP and GTF.

CONCLUSIONSP can promote GTF proliferation, and the SP content in wound is closely associated with the depth of the injury and wound healing capacity.

Objective To analyze the choice of implant materials,key points of operative proce- dures,prevention and management of postoperative complications in patients treated with cranioplasty. Methods Two hundred and twenty six patients with craniocerebral trauma underwent cranioplasty with different implant materials.Attention should be paid for the purpose of not tearing or injuring the dura ma- ter during operation.To take the dura mater up to the implant material and the edge of the bone flap,and put drainage under the scalp flap before closure of the incision.Results The clinical symptoms and neural function were improved in 146(64.6%)patients postoperatively.Postoperative complications mainly were infection,fluid collection and hematoma in the operative region.Follow-up showed the occur- rence of displacement or collapse of the implant materials in some patients.Conclusion Timely cra- nioplasty can not only resolve cosmetic problems but also improve clinical symptoms and neural function. The causes of postoperative complications are mainly related with the operative procedures and the materi- als used.

Objective To understand and master the infection status of key parasitic diseases in Baise City from 2006 to 2015, so as to provide evidence for the development and adjustment of the control strategy for parasitic diseases. Methods The relevant information of the final evaluation of the key parasitic diseases in 12 counties (cities and districts) of Baise City from 2006 to 2015 was collected, and analyzed. Results During the period of 2006-2015, a total of 20 654 person-times were investigated for parasitic diseases in Baise City and 1 147 persons were infected, with an average infection rate of 5.55%. In 2006, the infection rate was the highest (28.67%, 362/1 254), while the lowest was in 2013 (2.08%, 44/2 113). The infection rate of Clonorchis sinensis was the highest, and the infection rate of Ascaris lumbricoides was the second. The infection rates of the males and females were 5.35% (631/11 795) and 5.82% (516/8 859) respectively, with no significant difference between them (χ² = 2.175, P > 0.05). The highest infection rate existed in the 40-49 years group, the rural residents, the farmers and the crowd with the educational level of senior high middle school or above. Conclusions The infection rate of parasitic diseases presents a decline trend overall in Baise City from 2006 to 2013, however it rebounded in 2014 and 2015. The next step is to strengthen the prevention and control of parasitic diseases by promoting health education, regular insect repellent, and fecundity management.

Objective To explore the clinical characteristics and treatment scheme of periprosthetic joint infection(PJI)caused by Cutibacterium avidum(C.avidum).Methods The diagnosis and treatment process of a patient with PJI caused by C.avidum was summarized,and relevant literatures in the database were retrieved for review.Results A 65-year-old female patient with body mass index(BMI)of 31.1 kg/m2 underwent left humeral head prosthesis replacement surgery following a left proximal humerus fracture.Ten months after the surgery,the pa-tient exhibited poor wound healing and oozing,along with limited movement of the left shoulder joint,and was diag-nosed infection following shoulder arthroplasty.Patient underwent debridement of the infected lesion and removal of the prosthesis.The tissue,bone cement and prosthesis were cultured for C.avidum.Four literatures were re-trieved and screened,a total of 30 patients with PJI(28 cases hip joint infection and 2 cases shoulder joint infection)caused by C.avidum were reported through literature retrieval,and 78.6％(n=22)total hip arthroplasty(THA)surgeries were performed using direct anterior approach(DAA).The positive rate of preoperative joint fluid culture was 71.4％,29 cases underwent surgical combined with sensitive antimicrobials treatment.Except for one patient who had repeated infection and underwent three surgeries,other patients had a good prognosis.Conclusion PJI caused by C.avidum is mostly seen in THA patients who are obese and undergo DAA,with a few cases reported after shoulder arthroplasty.The high sensitivity of preoperative joint fluid culture provides an important basis for the development of surgical strategies and anti-infection protocols.

Objective:To explore the effects and mechanism of zedoary turmeric oil and its active components on the vascular endothelial growth factor A （VEGFA）， signal transducer and activator of transcription 3 （STAT3）， and mechanistic target of rapamycin （mTOR） in the ovarian cancer （OC）. Method:Network pharmacology technology was employed to analyze the mechanism of Curcumae Rhizoma on OC. Bioinformatics was used to analyze the expression of VEGFA， STAT3， and mTOR in OC and the effect on the prognosis of OC to explore the feasibility of zedoary turmeric oil in regulating VEGFA， STAT3， and mTOR in OC.The xenograft tumor model of nude mice was established， and the effects of zedoary turmeric oil and its active components on VEGFA， STAT3， and mTOR in OC were observed by hematoxylin-eosin （HE） staining， real-time fluorescence-based quantitative polymerase chain reaction （Real-time PCR）， Western blot， and immunohistochemistry （IHC）. Result:Bioinformatics analysis and literature research showed that VEGFA， STAT3， and mTOR played a special regulatory role in the occurrence and development of OC， and were potential key targets for the proliferation of OC. Network pharmacology analysis revealed that Curcumae Rhizoma could regulate multiple disease targets of OC， and mediate VEGFA， STAT3， and mTOR in OC through these multiple targets. As demonstrated by HE staining， the tumor cells in the model group were densely arranged， with no erosion on the edge and no vesicles inside. Compared with the model group， the cell density in other treatment groups was reduced， and strip-shaped erosion on the edge and small empty vesicles were observed in the tumor tissue， especially in the zedoary turmeric oil group. According to the results of Real-time PCR and IHC， zedoary turmeric oil and its active components could inhibit the mRNA and protein expression of VEGFA， STAT3， and mTOR in the OC tissue （P<0.05）. Conclusion:Zedoary turmeric oil and its active components could reduce the expression of VEGFA， STAT3， and mTOR in tumor tissue of nude mice， and inhibited the proliferation of OC through VEGFA， STAT3， and mTOR.

OBJECTIVETo analyze the efficacy and quality of life and safety for paclitaxel and carboplatin (TC) and TC combined with endostar in the treatment of advanced non-small cell lung cancer (NSCLC).

METHODSThis is a prospective, multicenter, randomized, double-blind, placebo-controlled clinical study. A total of 126 cases of untreated advanced NSCLC were enrolled in this study. There were 63 patients in the TC control arm and TC combined endostar arm, respectively. All enrolled patients were continuously followed-up for disease progression and death.

RESULTSThe objective response rate (ORR) of TC combined with endostar arm was 39.3%, and that of TC control arm was 23.0%, P = 0.078. The progression-free survival rates for TC combined with endostar arm and TC control arm were 78.3% and 58.8%, respectively, in 24 weeks (P = 0.017). The hazard ratio for the risk of disease progression was 0.35 (95%CI 0.13 to 0.90, P = 0.030). The median time to progression (TTP) of the TC combined with endostar arm was 7.1 months and TC arm 6.3 months (P > 0.05). The follow-up results showed that the median survival time (mOS) of the TC + Endostar arm was 17.6 months; (95%CI 13.4 to 21.7 months), and the TC + placebo arm 15.8 months (95%CI 9.4 to 22.9 months) (P > 0.05). The quality of life scores (LCSS patient scale) after treatment of the TC combined with endostar arm was improved, and that of the TC group was improved after completion of two cycles and three cycles of treatment. The quality of life scores compared with baseline after the completion of one cycle treatment was significantly improved for both the TC combined with endostar arm (P = 0.028 and), and TC arm (P = 0.036). It Indicated that TC combined with endostar treatment improved the patient's quality of life in the early treatment. The difference of adverse and serious adverse event rates between the two groups was not significant (P > 0.05).

CONCLUSIONSCompared with TC alone treatmrnt, TC combined with endostar treatment can reduce the risk of disease progression at early time (24 weeks), increase the ORR, and can be used as first-line treatment for advanced NSCLC. The TC combined with endostar treatment has good safety and tolerability, improves the quality of life, and not increases serious adverse effects and toxicity for patients with advanced NSCLC.

OBJECTIVETo determine whether antibiotic prophylaxis can reduce the risk of postoperative infective complications in patients undergoing percutaneous nephrolithotomy (PCNL) who have sterile preoperative urine.

METHODSMEDLINE, EMBASE, Cochrane Collaboration Reviews, CMCC and CNKI were searched for RCTs comparing antibiotic prophylaxis with placebo (or blank controls) for patients undergoing PCNL with preoperative sterile urine. The search strategy was made according to the Collaborative Review Group search strategy. Data were extracted by 2 reviewers using the designed extraction form. The software RevMan 4.2 was used to review management and data analysis.

RESULTSA total of 9 trails, 1 placebo controlled, 3 non treatment controlled, and 5 active controlled, involving 1018 patients, met the inclusion criteria. Prophylactic antibiotic use in patients at low risk undergoing PCNL significantly decreased fever (RR = 0.71, 95% CI: 0.54-0.92, P = 0.009), bacteriuria (RR = 0.39, 95%CI: 0.23-0.67, P = 0.0006) and bacteremia incidence (RR = 0.43, 95%CI: 0.25-0.73, P = 0.002). Effective antibiotic classes included quinolone which significantly decreased bacteriuria incidence (RR = 0.31, 95%CI: 0.12-0.82, P = 0.010) and nitrofurantoin which significantly decreased fever incidence (RR = 0.38, 95%CI: 0.24-0.61, P = 0.005). Extended course significantly decreased fever incidence (RR = 0.64, 95%CI: 0.47-0.87, P = 0.004) and bacteriuria incidence (RR = 0.35, 95%CI: 0.18-0.71, P = 0.003).

CONCLUSIONSProphylactic antibiotics can significantly decrease the incidence of postoperative infective complications. A significant decrease in bacteriuria incidence can be achieved with quinolones. Extended course is effective in decreasing fever, and bacteriuria incidence.

This study aims to investigate the inhibitory effect of Pien Tze Huang(PZH) on enterovirus 71(EV71). To be speci-fic, chemiluminescence method was adopted to evaluate the toxicity of PZH to African green monkey kidney(Vero) cells and human rhabdomyosarcoma(RD) cells, and cytopathic effect(CPE) method to assess the inhibition on EV71-GFP reporter virus and EV71 C4 wild-type virus. The results showed that PZH had low cytotoxicity to Vero cells and RD cells, with the half-maximal cytotoxic concentration(CC_(50)) of about 0.691 3-0.879 2 mg·mL~(-1) for the two. In addition, PZH can effectively inhibit the replication of EV71 within the non-cytotoxic concentration range, and dose-dependently alleviate the cytopathic changes caused by virus infection, with the half-maximal effective concentration(EC_(50)) of 0.009 2-0.106 3 mg·mL~(-1). On the basis of the above results, the green fluorescent protein(GFP), indirect immunofluorescence assay(IFA), and median tissue culture infective dose(TCID_(50)) were employed to assess and verify the anti-EV71-GFP and anti-EV71 C4 activity of PZH. The results demonstrated that PZH can dose-dependently lower the expression of GFP by EV71-GFP and structural protein VP-1 by EV71 C4 and decrease the production of progeny infectious viruses. The EC_(50) of PZH for EV71-GFP and EV71 C4 was about 0.006 0-0.006 2 mg·mL~(-1) and 0.006 6-0.025 6 mg·mL~(-1), respectively. This study suggested that PZH may exert antiviral activity by acting on EV71 and interfering with the expression of VP-1. At the moment, there is still a lack of specific anti-EV71 drugs. This study proposed a new idea for the symptomatic treatment of EV71 infections such as hand-foot-mouth disease and verified an effective drug for the treatment of EV71 infections.
