OBJECTIVETo observe the primary prevention role of Wuling Capsule (WC) on poststroke depression (PSD) patients.

METHODSAcute stroke patients were recruited and randomized into 2 groups by stratification, 55 in each group. All patients received same routine treatment of cardiovascular diseases. Patients in the experimental group additionally took WC (0.33 g each pill), 3 pills per day, three times per day; while those in the control group additionally took placebos, 3 pills per day, three times per day. Two weeks consisted of one therapeutic course. The diagnosis of PSD was performed once every other week. Those in accordance with PSD diagnosis discontinued any drug therapy. Those not in accordance with PSD diagnosis continued the drug therapy for 1-12 therapeutic course(s) (in total of 6 months). If they were still not in accordance with PSD diagnosis, then they discontinued the drug therapy. The morbidity of PSD, the average time of depression occurrence, Hamilton depression rating scale (HAMD) score, and adverse reactions were observed.

RESULTSThe 1-, 3-, and 6-month morbidity of PSD was 8%, 16%, and 34% in the experimental group, while they were 19.6%, 29.4%, and 54.9% in the control group. The occurrence rate was lower in the experimental group than in the control group. Besides, there was statistical difference in the 6-month occurrence rate between the two groups (chi2 = 4.465, P < 0.05). The average time of PSD occurrence was longer in the experimental group than in the control group (14.96 +/- 8.31 weeks vs. 9.36 +/- 6.06 weeks; t=6.762, P < 0.05). The HAMD score at the PSD occurrence was 11.96 +/- 2.14 in the experimental group, lower than that of the control group (14.57 +/- 4.24), showing statistical difference (t=5.641, P < 0.05).

CONCLUSIONWC was superior to the placebos in lowering the incidence of PSD, delaying the occurrence time of PSD, attenuating the depression degree of PSD, and had certain preventive effect on the incidence of PSD.

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 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.

Subparalyzing dose of nodepolarizing relaxants prior to injection of succinylcholine has been used to prevent various adverse effects induced after succinylcholine. For investigating interactions between succinylcholine and small doses of four non-depolar-izing agents, the 112 subjects that were ASA class 1-2 and no existing neuromuscular conduction system disorder were divided into 5 groups that were control group(only succinylcholine 1 mg/kg) and pretreated group d-tubocurarine 0.5 mg/kg, atracurium 0.08 mg/kg, vecuronium 0.01 mg/kg and pancuronium 0.01 mg/kg. In each group, the plasma concentration of K+ and PChE before and after use of succinylcholine, fasciculation, onset and recovery time of succinylcholine block and intubating conditon were observed. The results are as follows; In the pretreated group, there were no significant changes of plasma concentration of K+ and plasma cholinesterase(Table 3) but diminished the incidence of fascieulation, delayed the onset time and shorted the recovery time of succinylcholine block(Table 4), and worse in intubating condition(Table 5) except pancuronium treated group. It was concluded that these seem to make worse condition of intubation, while small doses of nondepolarizing muscle relaxants except pancuronium antagonize depolarizing muscle relaxant.

Severe head injury results in the suppression of cellular immunity associated with dysfunctioning of effector lymphocytes, such as helper T cells(CD4) (and cytotoxic T cells(CD8). Despite progress in the management of increased intracranial pressure following head injury, infection remains the most common complication and the primary cause of prolonged hospitalization and death. This study attempts to assess the cellular immune function following head injury according to the degree of severity, and to establish the clinically available parameters of cell mediated immune(CMI) function, which can then be used for coherent prediction of infection risk. Eighteem head injury patients without severe systemic injury, who divided into three subgroups depending on the severity of head injury, were estimated with the use of CMI multitest kit(Merieux Institute, France) to test delayed-type hypersensitivity(DTH) and enumerated the circulating lymphocyte subpopulation(pan T-cell marker CD3, helper T cell marker CD4, cytotoxic T cell marker CD8 and B-cell marker CD19) on the 1st, 7th, and 21th day of injury. Patients were monitored for evidence of infection for this period. Fourteen patients had no reaction to any antigens of the DTH skin test(anergy) and the remaining four patients had also some degree of anergy. Seven patients became infected and all of them were anergic. There were significant decrease of circulating effector T lymphocytes, both CD4-positive and CD8-positive cells, within 24 hours of injury in the mild as well as the moderate and severe head injury group. CD4-positive cells were nearly completely recovered by the 7th day of injury. CD8-positive cells had sustained significant decrease even after 3 weeks of injury. There was no significant change in pan T-cells(CD3-positive cells) and B-cells(CD19-positive cells). The results suggest that DTH skin test and effector T cell enumeration are both relatively simple and highly sensitive parameters for monitoring CMI function. Especially, anergy of DTH skin test can be used for indicator to predict risk of infection. Mild as well as moderate and severe head injuries may result in the suppression of cellular immunity associated with the dysfunctioning of effector T cell.

Technological advances in video camera, high resolution monitors and optical systems have produced considerable process in endoscopic surgery. Recently we have experienced transthoracic endoscopic sympathectomy(TES) for the treatment of Buerger's disease of both hands in a 47 years old male healthy patient. For the TES, one lung ventilation is necessary to provide adequate surgical access, so this patient had general anesthesia with a disposable left sided Robertshaw double lumen endobronchial tube. The patient was monitored for arterial pressure, herat rate, ECG, pulse oximetry, end-tidal carbon dioxide concentration, peak inspired airway pressure and arterial blood gas analysis. Potenial intraoperative problems wese hypoxemia during one-lung anesthesia, hypotension and hypercarbia occurred by insufflation of carbon dioxide into the chest cavity. Our patient also developed moderate hypoxemia which was corrected by application of high frequency jet ventilation with low driving pressure during right sided operation, and increased significantly arterial carbon dioxide tension about 8-12 mmHg during one lung ansthesia. We reviewed our experience and discussed the anesthetic technique and perioperative problems encounterd in the patient undergoing transthoracic endoscopic sympathectomy for Buerger's disease.

OBJECTIVETo investigate the association of V89L polymorphism of the SRD5A2 gene with the prognostic factors of prostate cancer (PCa).

METHODSWe identified the V89L polymorphic sites of the SRD5A2 gene after Rsa-1 restriction enzyme digestion, observed the distribution of V89L (VV, VL and LL) polymorphism in 112 PCa and 89 benign prostate hyperplasia (BPH) patients, and determined the association of V89L polymorphism with the age, free PSA (fPSA), total PSA (tPSA), fPSA/tPSA ratio, tumor stage and Gleason score of the PCa patients.

RESULTSNo statistically significant differences were found in the V89L polymorphism-induced genetic risk frequencies between the PCa and BPH groups (chi2 = 3. 606, df = 2, P = 0. 165), nor any significant correlation between the genotypes of VV and VL + LL and the differences in the fPSA, tPSA, fPSA/tPSA ratio, tumor stage, Gleason score and age of the PCa patients. VV and VL + LL showed no obvious association with the prognostic factors of PCa.

CONCLUSIONV89L polymorphism is not related with the prognosis of PCa, but may be indirectly associated with its risk.
