ABSTRACT

Excessive application of chemical fertilizer has caused many problems in Angelica dahurica var. formosana planting, such as yield decline and quality degradation. In order to promote the green cultivation mode of A. dahurica var. formosana and explore rhizosphere fungus resources, the rhizosphere fungi with nitrogen fixation, phosphorus solubilization, potassium solubilization, iron-producing carrier, and IAA-producing properties were isolated and screened in the rhizosphere of A. dahurica var. formosana from the genuine and non-genuine areas, respectively. The strains were identified comprehensively in light of the morphological characteristics and ITS rDNA sequences, and the growth-promoting effect of the screened strains was verified by pot experiment. The results showed that 37 strains of growth-promoting fungi were isolated and screened from the rhizosphere of A. dahurica var. formosana, mostly belonging to Fusarium. The cultured rhizosphere growth-promoting fungi of A. dahurica var. formosana were more abundant and diverse in the genuine producing areas than in the non-genuine producing areas. Among all strains, Aspergillus niger ZJ-17 had the strongest growth promotion potential. Under the condition of no fertilization outdoors, ZJ-17 inoculation significantly promoted the growth, yield, and accumulation of effective components of A. dahurica var. formosana planted in the soil of genuine and non-genuine producing areas, with yield increases of 73.59% and 37.84%, respectively. To a certain extent, it alleviated the restriction without additional fertilization on the growth of A. dahurica var. formosana. Therefore, A. niger ZJ-17 has great application prospects in increasing yield and quality of A. dahurica var. formosana and reducing fertilizer application and can be actually applied in promoting the growth of A. dahurica var. formosana and producing biofertilizer.

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy of proximal femoral nail anti-rotation(PFNA) and dynamic hip screw(DHS) for the treatment of unstable intertrochanteric fractures in the elderly.@*METHODS@#From January 2012 to December 2015, 83 elderly patients with unstable intertrochanteric fracture of femur were divided into 45 cases treated with PFNA and 38 cases treated with DHS. In the PFNA group, there were 24 males and 21 females, aged 82 to 94(88.35±6.12) years old, duration was 1.5 to 10 (4.33±1.07) h, causes of injury involved 33 traffic accidents, 10 falls at high altitude, 2 falls; Evans-Jensen classification involved 21 cases of IIIA, 18 cases of IIIB and 6 cases of IV. In DHS group, there were 20 males and 18 females, aged 83 to 95 (88.77±5.52) years old, duration was 1 to 10 (4.37±1.05) h, 27 traffic accidents, 10 high-altitude falls and 1 fall injury, and Evans-Jensen classification involved 18 cases of IIIA, 15 cases of IIIB and 5 cases of IV. The operation time, intraoperative bleeding volume and discharged complications were observed and compared between the two groups. The Mos 36-item Short Form Health Survey (SF-36) was used to measure the quality of life before and 12 months after operation. Harris score was used to evaluate hip function 12 months after operation.@*RESULTS@#The operation time, intraoperative bleeding volume and complication rate in PFNA group were significantly lower than those in DHS group(<0.05); both groups were followed up for 12 months without falling off. The Harris score and SF-36 score at 12 months after operation in both groups were higher than those before operation(<0.05), and the excellent and good rate in PFNA group was significantly higher than that in DHS group(<0.05).@*CONCLUSIONS@#Compared with DHS, PFNA is more simple, less traumatic, less complications, better short-term survival rate and better quality of life for elderly patients with unstable intertrochanteric fracture of femur. PFNA can be used as an optimal treatment for elderly patients with unstable intertrochanteric fracture of femur.

ABSTRACT

Chinese medicine (CM) has been used in clinical treatment for thousands of years in China, Japan, Korea, and other countries. CM is at present attracting many attentions around the world for reproductive health care and disease prevention, including treatment of female infertility. This review focuses on the CM treatment for female infertility patients, and supplies a summary on the efficacy, safety, and mechanism of some Chinese herbal medicines, herbal medicine-derived active compounds, and acupuncture. A large number of researches have reported that CM could alleviate or even cure female infertility by regulating hormone, improving reproductive outcome of in vivo fertilization, affecting embryonic implantation, curing polycystic ovarian syndrome, endometriosis, pelvic inflammatory disease, relieving mental stress, and regulating immune system. Meanwhile, a few studies claimed that there was little adverse reaction of CM in randomized controlled trials. However, up to present there is a lack of adequate evidences with molecular mechanistic researches and randomized controlled trials to prove the CM as an effective and safe treatment for infertility. Thus, utility of CM as a complementary medicine will be a feasible method to improve the outcome of female infertility treatment.

ABSTRACT

273 bacterial strains were isolated from 20 Chinese longsnout catfish samples. The biochemical characteristics of all strains conformed to the species description of Aeromonas veronii bv. veronii on the basis of Vitek GNI+ card. Furthermore, 16S rDNA, gyrB and rpoD sequences of the representative strain PY50 were sequenced and showed high similarity with A. veronii bv. veronii in Genbank. Antibiotic-resistance of the representative strain PY50 was assessed by the Kirby-Bauer disk diffusion method, and the results showed it was susceptible and moderately susceptible to 13 and 4 of the 21 antimicrobial agents tested. Extracellular products of strain PY50 contained gelatinase, lecithinase, elastase, most of lipase and lipopolysaccharide. Virulence of strain PY50 and extracellular products to Chinese longsnout catfish were also tested, and LD50 were about 3.47~10(4) CFU per fish and 11.22 ƒÊg per fish in intraperitoneal injection respectively. This is the first report that A. veronii bv. veronii was the pathogenic agent of ulcerative syndrome in Chinese longsnout catfish.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical effect of the disk-up sinus reamer (DSR) applied to transcrestal maxillary sinus floor elevation with simultaneous placement of implants.</p><p><b>METHODS</b>Thirty-seven patients underwent transcrestal maxillary sinus floor elevation with fifty-one implants placed simultaneously using the DSR. The residual bone height (RBH) was 3 to 8 mm, (5.61 ± 1.61) mm on average. The safety of this technique and the pain index during the operation was evaluated. The final prostheses were restored in 3-6 months postoperatively. The follow-up period was 3 to 24 months. The stability and osseointegration of the implants were clinically evaluated, and the endo-sinus bone gain around the implants were measured.</p><p><b>RESULTS</b>The elevation height ranged from 2 to 8 mm, with an average of (4.75 ± 1.55) mm. There was no detectable sinus membrane perforation, no serious suffering or uncomfortable subjective sensation in any patients during operation with a pain index of (2.22 ± 0.98). During the follow-up period, no sinus complication was observed. Favorable osseointegration was obtained. There were no implants or prostheses which were loose or lost. The survival rate was 100%. The radiographic results demonstrated that the endo-sinus bone gain tended to reach stabilization after 6 months and the marginal bone loss was (1.20 ± 0.72) mm after 12 months.</p><p><b>CONCLUSIONS</b>Transcrestal maxillary sinus floor elevation with simultaneous implant placement by DSR is a safe, invasive and handy technique, with higher elevation height, fewer clinical complications and less pain. It shows satisfactory clinical results in short term and a long-term observation is still needed.</p>

ABSTRACT

<p><b>BACKGROUND AND OBJECTIVE</b>Previous studies have shown that Bmi-1 is overexpressed in a variety of tumors, suggesting that Bmi-1 plays an important role in tumorigenesis. In this study, we investigated the effect of Bim-1 siRNA on cell proliferation, cell cycle, cell apoptosis and migration of human esophageal carcinoma EC9706 cells, and explored its potential mechanisms.</p><p><b>METHODS</b>Bmi-1 small interfering RNA (siRNA) was transferred into EC9706 cells. Then, cell proliferation was measured using cell counting kit-8 (CCK-8), cell cycle and cell apoptosis were analyzed by flow cytometry, cell migration ability was detected using Boyden chamber assay, and the mRNA and protein expression levels of Bmi-1, p16, Bcl-2, Bax, and MMP-2 were determined using real-time polymerase chain reaction (PCR) and Western blot analysis, respectively.</p><p><b>RESULTS</b>Bmi-1 siRNA treatment significantly inhibited the expression of Bmi-1 at both mRNA and protein levels in EC9706 cells. Cell proliferation rate decreased dramatically in the Bmi-1 siRNA treated group than in the untreated group and in the scrambled siRNA treated group (both P < 0.001). In Bmi-1 treated group, the percentage of cells at G(0)/G(1) stage was 71.93%, which was higher than that in the untreated group (47.36%) or scramble siRNA treated group (48.47%) (both P < 0.001). Early cell apoptosis rate also increased significantly in the Bmi-1 siRNA treated group (both 17.32%) than in the untreated group (2.61%) and in the scramble siRNA treated group (2.73%) (both P < 0.001). Further experiment suggested that downregulation of Bmi-1 led to less cell migration. In EC9706 cells transfected by Bmi-1 siRNA, the expression levels of p16 and Bax increased, while the expression level of Bcl-2 decreased.</p><p><b>CONCLUSIONS</b>Bmi-1 downregulation in esophageal carcinoma cells inhibits cell proliferation, cell cycle, and cell migration, while increases cell apoptosis. These results suggest that Bmi-1 is a potential molecular target of treating esophageal cancer.</p>

ABSTRACT

This study was aimed to investigate the incidence of thrombosis in patients with primary thrombocytosis (PT) and its correlation with function changes of platelets, and to explore the effect of thromboxane A2 (TXA2) inhibitor-ozagrel sodium on platelet activity and its efficacy for prevention and treatment of thrombosis. The CD62P and PAC-1 levels on platelet surface were detected by flow cytometry; the levels of TXB2 (metabolic product of TXA2) and 6-keto-PGFIalpha (metabolic product of prostacyclin) were detected by FLISA. The function change of platelets and its correlation with thrombosis were observed and compared in PT patients with and without thrombosis. The results indicated that the TXB2, PAC-1 and CD62P level, and TXB2/6-keto-PGF1alpha ratio in PT patients with thrombosis were higher than those in PT patients without thrombosis before treatment with ozagrel sodium (p<0.01). After treatment with ozagrel sodium, the function indexes of platelets such as CD62P, PAC-1, TXB2 and TXB2/6-keto-PGF1alpha except 6-keto-PGF1alpha in PT patients with and without thrombosis decreased obviously (p<0.01), but there was no significant difference in TXB2, 6-keto-PGF1alpha and TXB2/6-keto-PGF1alpha levels between PT patients with and without thrombosis except CD62P and PAC-1. It is concluded that the multi-index of platelets in PT patients with thrombosis are higher than that in PT patients without thrombosis, the activation of platelet function is a high risk factor for thrombosis of PT patients. The ozagrel sodium can obviously reduce the platelet activation, decrease the production of TXA2 and ameliorate the TXB2/6-keto-PGF1alpha ratio. The ozagrel sodium not only possesses therapeutic effect, but also preventive efficacy for thrombosis.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the middle and distal circum peeling with bleeding control technique for redundant prepuce.</p><p><b>METHODS</b>The middle and distal part of prepuce was circum peeled with bleeding control and electrical scalpel. More preputial inner plate was reserved.</p><p><b>RESULTS</b>From January 2004 to July 2008, 51 patients with redundant prepuce were treated with this procedure. The average blood loss was 1 to approximately 2 ml with minimal edema. The proportion of inner and outer plates was suitable.</p><p><b>CONCLUSIONS</b>This technique has the advantages of minimal blood loss and slight edema. The cosmetic result is also satisfactory.</p>
