OBJECTIVETo study the kinetogenic effects of serum containing Semen Arecae, Dandelion, Semen raphani and Atractylodes macrocephala on the colonic smooth muscle cells of rats.

METHODSSerum containing Chinese materia medicas was made according to standard methods. Smooth muscle cells were isolated from the muscle layers of Wistar rat's colon, referred to modified Bitar's method. The contractile response of colonic smooth muscle cells to serum containing Chinese materia medicas (10%, 50%, 100% concentration) and other medicines (blank and 1 x 10(-3) mol/L acetylcholine) were separately observed. The contractility was presented by the decrease of the cell length between the drug groups and the control.

RESULTSSerum containing each Chinese materia medica can make dose-dependent contraction at different concentrations (P < 0.05), but the strongest effect of each serum had no significant difference (P > 0.05).

CONCLUSIONSerum containing Semen Arecae, Dandelion, Semen raphani and Atractylodes macrocephala can make notable contraction on colonic smooth muscle cells in rats.

Objectives To analyze the diagnosis and management of steroid-resistant nephrotic syndrome (SRNS) accompanied with irreversible leukoencephalopathy in children. Methods The clinical, laboratory and imaging data were retrospectively analyzed in a SRNS child accompanied with irreversible leukoencephalopathy. A literature review was performed. Results After clinical diagnosis of SRNS, glucocorticoid, immunosuppressant, and hemodialysis were administrated for 10 months. During the course of treatment, the seizures, visual problems, and hypertension were repeatedly occured. The cranial MRI showed bilateral occipital parietal lobe hyperintensity and right frontotemporal lobe hyperintensity on T2-weighted imaging and bilateral occipital parietal lobe hypointensity on T2-Flair imaging, which indicated that encephalomalacia was accompanied with gliosis. Conclusions A variety of reasons may induce leukoencephalopathy in children. The accompanied irreversible leu-koencephalopathy should be strongly considered in management of SRNS.

Thrombus is a major factor leading to cardiovascular diseases such as myocardial infarction and stroke. Although fibrinolytic anti-thrombotic drugs have been widely used in clinical practice, they are still limited by narrow therapeutic windows, short half-lives, susceptibility to inactivation, and abnormal bleeding caused by non-targeting. Therefore, it is crucial to effectively deliver thrombolytic agents to the site of thrombus with minimal adverse effects. Based on the long blood circulation and excellent drug-loading properties of human serum albumin (HSA), we employed genetic engineering techniques to insert a functional peptide (P-selectin binding peptide, PBP) which can target the thrombus site to the N-terminus of HSA. The fusion protein was expressed using Pichia pastoris and purified by Ni-chelating affinity chromatography. After being loaded with gold nanoparticles (Au NPs), the fusion protein formed homogeneous and stable nanoparticles (named as PBP-HSA@Au) with a diameter of 17.7 ± 1.0 nm and a zeta potential of -11.3 ± 0.2 mV. Cytotoxicity and hemolysis tests demonstrated the superb biocompatibility of PBP-HSA@Au. Platelet-targeting experiments confirmed the thrombus-targeting ability conferred by the introduction of PBP into PBP-HSA@Au. Upon near-infrared ray (NIR) irradiation, PBP-HSA@Au rapidly converted light energy into heat, thereby disrupting fibrinogen and exhibiting outstanding thrombolytic efficacy. The designed HSA fusion protein delivery system provides a precise, rapid, and drug-free treatment strategy for thrombus therapy. This system is characterized by its simple design, high biocompatibility, and strong clinical applicability. All animal experiments involved in this study were carried out under the protocols approved by the Animal Experiment Ethics Committee of Jiangnan University [JN. No20230915S0301015(423)].

OBJECTIVETo observe the clinical effects of the no-flip procedure with the Chinese Shang Ring when circumcising adult males with redundant prepuce or phimosis, and to discuss its advantages and disadvantages.

METHODSUsing the no-flip Shang Ring technique, we performed circumcision for 167 adult males aged 18 -72 (mean 27.8) years with redundant prepuce or phimosis, and analyzed the clinical data, including the operation time, postoperative complications, ring-removal time, and postoperative appearance of the penis.

RESULTSComplete follow-up data of 94 cases (56.29%) were obtained. The mean operation time was (5.03 +/- 0.71) minutes and the average ring-removal time was (18.83 +/- 6.70) days. The primary postoperative complications were edema (35 cases [37.23%] at 2 weeks and 9 cases [9.57%] at 4 weeks), including 2 severe cases (2.13%), and infection (3 cases [3.19%]). The pain scores were 2.01 +/- 2.46 during the procedure and 4.52 +/- 2.53 at 24 hours postoperatively. Slipping of the outer ring occurred in 1 case, and delayed removal of the ring in 30 cases (31.91%).

CONCLUSIONAdult male circumcision with the no-flip Shang Ring technique is recommended for its short operation time, simple procedure, fewer postoperative complications, less pain, and better incision appearance.

Objective To evaluate the feasibility and safety of cap-assisted endoscopic nylon loop ligation (C-ENLL) as a new and simple method on gastric fundus submucosal tumors. Methods 74 cases with small gastric fundus submucosal tumors ≤2.00 cm in diameter were reviewed between January 2015 and June 2016. All cases were treated by C-ENLL. The clinical efficacy was analyzed. Results All the 74 patients underwent endoscopic ultrasonography before operation, 70 cases originated from the muscularis propria, 3 cases originated from the muscularis mucosae, 1 case originated from the submucosa. The average diameter of the lesions ranged 0.50 ～ 1.80 cm. C-ENLL achieved an en bloc resection rate of 100.0％, with a mean total procedure time of 26 min. Two patients developed delayed perforation, were treated with nylon rope and metal clip purse suture wound. All of whom were managed successfully. There was no delayed bleeding after operation. Pathological examination showed that 66.2％ (49/74) of the tumors were gastrointestinal stromal tumors. No tumor recurrence was observed during the follow-up. Conclusion The C-ENLL may be a feasible and safe method for the treatment of small gastric fundus submucosal tumors.

OBJECTIVETo investigate the expression of long non-coding RNA HOTAIR in the plasma of breast cancer patients and its value in the diagnosis of breast cancer.

METHODSHOTAIR levels were measured in 24 tumor tissues and 70 plasma samples from breast cancer patients using quantitative real-time PCR. The correlations of plasma HOTAIR level with the clinicopathological features of the patients were analyzed. A multivariate logistic regression model was established to analyze the value of plasma HOTAIR in comparison with plasma CA153 and CEA levels for breast cancer diagnosis. We further detected HOTAIR levels in the plasma and breast cancer tissues of 24 patients before and after operation and investigated their correlation.

RESULTSBreast cancer patients had increased expressions of HOTAIR in the tumor tissues and plasma, and plasma HOTAIR level was significantly correlated with estrogen receptor (ER) level (P=0.004) and lymph node metastasis (P=0.010). Receiver operating characteristic (ROC) curve and the multivariable logistic regression model showed that the area under ROC curve (AUC) of plasma HOTAIR was 0.82 (P<0.001) for breast cancer diagnosis with a diagnostic sensitivity and a specificity of 73.3% and 93.3%, respectively. The diagnostic power and specificity of plasma HOTAIR was much higher than those of CA153 (AUC=0.66, P=0.030) and CEA (AUC=0.52, P=0.001), and the combination of the 3 markers further enhanced the diagnostic power (AUC=0.84) and specificity (96.7%). Plasma HOTAIR level was significantly reduced in the patients after the operation (P<0.0001) and showed a moderate correlation with its expression in tumor tissues (r=0.62, P<0.0001).

CONCLUSIONPlasma HOTAIR may serve as a potential biomarker for breast cancer diagnosis.

BACKGROUNDRecent studies have identified signal transducer and activator of transcription 4 (STAT4) as a susceptibility gene for systemic lupus erythematosus (SLE) in different populations. In order to examine whether the allele distribution of the single nucleotide polymorphism (SNP) in gene STAT4 rs7574865 in patients with SLE is different from those of healthy controls in Chinese Northern Han population, we investigated whether the variants of STAT4 rs7574865 were associated with any specific clinical features of SLE.

METHODSWe genotyped SNPs in STAT4 rs7574865 in 252 patients with SLE and 497 healthy controls. All subjects were from the Northern part of Chinese Han population. The genotypes in rs7574865 were determined by polymerase chain reaction (PCR) and consequence direct sequencing of PCR products in the DNA samples.

RESULTSThere was a significant difference in distribution of the SNPs in rs7574865 between the SLE patients and healthy controls. Compared with healthy controls, there was a significant correlation between TT genotypes in rs7574865 and the risk of SLE when GG genotype was used as a reference genotype after adjusting for gender and age. The frequency of T allele in the SLE patients was strongly significantly higher than that of healthy controls. Furthermore, there was a significant difference in the distribution of SNP in rs7574865 between male and female SLE patients, when compared with healthy controls. The frequency of T allele in rs7574865 in male patients was significantly higher than that of male healthy controls or female patients. There was no significant correlation between the frequencies of T allele in STAT4 rs7574865 and the clinical features of SLE.

CONCLUSIONSThe SNP rs7574865 in STAT4 is strongly associated with risk of SLE in the Chinese Northern Han population. The TT genotype and T allele in STAT4 rs7574869 are susceptibility factors for SLE, especially for male SLE patients.
