[Identification of Cordyceps cicadae and Tolypocladium dujiaolongae based on ITS sequences and chemical pattern recognition method].

Based on ITS sequences, the molecular identification of Cordyceps cicadae and Tolypocladium dujiaolongae was carried out, and high-performance liquid chromatography(HPLC) fingerprint combined with chemical pattern recognition method was established to differentiate C. cicadae from its adulterant T. dujiaolongae.

Nitroglycerin ameliorates liver injury and regulates adaptive immunity in mice.

This study aimed to assess the protective effect of nitroglycerin, a commonly used drug in cardiovascular diseases, on mice with acute liver injury induced by carbon tetrachloride (CCl ). The mice were randomly divided into three groups: control, CCl , and CCl  + nitroglycerin. They were killed at 0, 6, 12, 24, and 48 h after treatment.

Catalytic amidation of natural and synthetic polyol esters with sulfonamides.

Triacylglycerides are naturally abundant and renewable feedstock for biofuels and chemicals. In this report, these seemingly stable compounds are shown to be reactive toward a variety of sulfonamides under Lewis acid catalysis. In these reactions, alkyl C(sp)-O bonds are cleaved and C-N bonds constructed, providing functionalized value-added products directly from renewables.

[Expression of receptor activator of nuclear factor-κB ligand in keratocystic odontogenic tumor before and after decompression].

Purpose: To investigate the expression of receptor activator of nuclear factor-κB ligand (RANKL) in keratocystic odontogenic tumor (KCOT) before and after decompression.

Methods: Twenty two pairs of paraffin-embeded tissue specimens of KCOT were collected and subjected to immunohistochemical analysis of RANKL.The data were analyzed with SPSS17.

T helper cell dysregulation with hepatitis B and rebalance with glucocorticoids.

Aim: To investigate T helper 17/regulatory T cell alterations in early severe hepatitis B and the effect of glucocorticoids.

Methods: The study included 20 patients in the early stage of severe hepatitis B (SHB) and 11 healthy controls. All patients had elevated T helper 17 (Th17) levels, decreased regulatory T (Treg) cell levels, and significant Th17/Treg ratios.

Establishment of a new quantitative detection approach to adefovir-resistant HBV and its clinical application.

Aim: To establish the more feasible and sensitive assessment approach to the detection of adefovir (ADV) resistance-associated hepatitis B virus (HBV) quasispecies.

Methods: Based on the characteristics of rtA181V/T and rtN236T mutations, a new approach based on real-time fluorescent quantitative polymerase chain reaction (RT-PCR) was established for the detection of ADV-resistant HBV quasispecies, total HBV DNA, rtA181 and rtN236 mutations in blood samples from 32 chronic hepatitis B (CHB) patients with unsatisfactory curative effect on ADV and compared with routine HBV DNA sequencing.

Results: Both the sensitivity and specificity of this new detection approach to ADV-resistant HBV quasispecies were 100%, which were much higher than those of direct HBV DNA sequencing.

Clinical observation on the treatment of post-cesarean hypogalactia by auricular points sticking-pressing.

Objective: To explore the effect of auricular points sticking-pressing (APSP) in treating post-cesarean hypogalactia (PCH).

Methods: A randomized, controlled, single-blinded clinical trial on 116 patients with PCH was carried out. They were equally assigned to the treatment group and the control group.

[Common infantile scrotum or testicle disease diagnosed by high frequency ultrasonoscopy].

Objective: To diagnose and distinguish the swell in the infantile scrotum or testicle by the high frequency ultrasonoscopy so as to find the acoustic imaging characters and clinical application value.

Methods: With the high frequency linear-array probe used, the multi-section and two-side contrast scanning checks were conducted on 46 cases of the infantile scrotum or testicle swell and position with abnormal physical signs. The structures of scrotum, testicle, epididymis and spermatic cord as well as the positions, sizes, forms and interior echoes were observed.

[Investigation of the spatial variability of nitrogen and phosphorus in purple soils in Jiangjing City, Sichuan, China].

In this paper, the spatial distribution pattern of the total nitrogen, available nitrogen, available phosphorus and total phosphorus in surface purple soil (0-20 cm) with a city region were analyzed by applying geostatistics combined with GIS. The spatial distribution pattern of the four soil nutrient parameters were quantitatively described with semivariogram and the soil nutrient content distribution pattern was constructed by using Ordinary Kriging and lognormal Kriging optimal interpolation. The results indicated that total nitrogen, available nitrogen showed a normal distribution, the others with a lognormal distribution; the analyst of semivariogram indicated that the total nitrogen showed the pure nugget effect with the nugget of 0.
