Bone marrow mesenchymal stem cells (BMSCs) are a kind of pluripotent stem cells derived from bone marrows, which can not only support hematopoiesis, but also have capabilities of multidifferentiation, high-proliferation and self-renewing. They have become one of hotspots in stem cell studies. Studies on in vitro intervention with BMSCs with TCMs have made remarkable progress in recent years. According to the findings, some traditional Chinese medicines can promote proliferation of BMSCs, some can inhibit the apoptosis of BMSCs, while others can induce BMSCs to differentiate into multiple cell types, such as osteoblast. Furthermore, some studies also involved relevant action mechanisms. The authors summarized the advance in relevant studies by reference to relevant literatures of this field.

The NSP2 gene of porcine reproductive and respiratory syndrome virus (PRRSV)S1 strain was partly amplified and cloned into a prokaryotic expression vector pGEX-6P-1 and a fusion protein GST-tNSP2 with molecular weight of 50 kDa was expressed in E.coli. The purified GST-tNSP2 protein showed a strong reaction with the PRRSV-positive sera in Western blot assay. Balb/c mice were immunized with the purified protein, and the splenocytes of the immunized mice were fused with murine myeloma cells SP2/0. After subcloning by 3 times, two hybridoma clones which produced McAbs steadily were screened by ELISA, named 3H3 and 2B5. They all reacted strongly with the PRRSV S1 infected Marc-145 cells in IFA, but not with the PRRSV SY0608 strain. Both of the McAbs belong to IgG1 isotype, and their light chains belong ? type. The expressed GST-tNSP2 protein and McAbs could be used for identification of PRRSV isolates and functional analysis of NSP2.

Objective To observe the changes of cardiac function and carotid artery structure in elderly hypertensive patients with different left ventricular geometric patterns. Methods Seventy-eight elderly patients with essential hypertension were divided into 4 groups according to left ventricular geometric patterns by ultrasonography: normal ventricular geometry group(n=34),concentric remodeling group(n=18),concentric hypertrophy group(n=11)and eccentric hypertrophy group(n=15).The 24-h ambulatory blood pressure,left ventricular function,carotid artery intima-media thickness(IMT),hemodynamic parameters and incidence of plaque were measured and compared among groups.Results Patients in concentric hypertrophy group had higher 24-h average systolic blood pressure in comparison with those in normal ventricular geometry group and concentric remodeling group(P

Objective To evaluate the role of gamma curve fitting technique of contrast-enhanced ultrasound in quantitative analysis of microcirculation in renal solid lesions. Methods A total of fifty patients with renal parenchyma solid lesions were performed contrast-enhanced ultrasound. The images were analysed by computer with gamma fitting analysis of contrast-enhanced ultrasonic system. The quantitative parameters were obtained by the time-intensity curves, such as ascending slope (a3), descending slope (a2), arrival time (AT), time to peak intensity (TTP), basic intensity (BI), peak intensity, amplification (AMP), area under the curve (AUC), mean transit time (MTT) and perfusion index (PI). The parameters were compared between renal malignant and benign solid lesions. Results Fast-in and fast-out was the main perfusion mode in renal malignant tumors while slow-in and slow-out was found in renal angiomyolipoma (AML). The perfusion modes in renal malignant tumors and renal AML were fast-in and fast-out in 28 cases and 0 case, fast-in and slow-out in 4 cases and 1 case, slow-in and fast-out in 5 cases and 1 case, and slow-in and slow-out in 1 case and 10 cases, respectively. There were significant differences in the quantitative parameters such as a2, AUC and PI between renal malignant tumors and renal AML obtained by the time-intensity curves (P<0.05). Conclusion Gamma fitting analysis of contrast-enhanced ultrasound system can provide quantitative information of microcirculation of renal tumors, which helps to differentiate benign renal tumors from malignant ones.

AIM: To analyze the effect of compound xuesaitong combined with conbercept on central macular retinal thickness (CMT), fluorescein fundus angiography and best corrected visual acuity(BCVA) in pathological patients with choroidal neovascularization (CNV).METHODS:A total of 60 cases (60 eyes) with pathological myopia and CNV who were admitted to our hospital during January to October 2016 were enrolled in the study.They were divided into observation group and control group, 30 cases in each group.Observation group was treated with compound xuesaitong combined with conbercept.Control group was treated with conbercept only.Changes of CMT, intraocular pressure (IOP), area of CNV, BCVA and serum vascular endothelial growth factor (VEGF) before surgery, 4 and 12wk after surgery were compared.Complications during follow-up were statistically analyzed.RESULTS: At 12wk after surgery, the total effective rate was 97% in observation group, 80% in control group and the difference was significant (P<0.01).The CMT, IOP, area of CNV and serum VEGF levels were significantly lower or smaller than those before surgery while BCVA was significantly higher than that before surgery (P<0.01).There were no local complications of systematic severe complications.CONCLUSION: Compound xuesaitong combined with conbercept can effectively reduce CMT and IOP, reduce the area of CNV and significantly improve visual acuity.Its anti-VEGF effect is obvious, safe and feasible.

Objective To explore the changes in serum and urine electrolytes of children with neurally media-ted syncope (NMS)after oral rehydration salts (ORS)[Ⅰ]treatment.Methods The study group included 135 patients [60 male and 75 female,aged 4 -16 years,average of (10.20 ±2.68)years old]with unexplained syncope and prodro-mal symptoms of syncope in our hospital between May 2014 and April 2015.The patients underwent head -up tilt test (HUTT),and completed serum electrolytes and 24 -hour urine electrolytes,and the serum electrolytes and 24 -hour u-rine electrolytes in different hemodynamic type of HUTT were compared.Positive HUTT patients were treated with health education and ORS[Ⅰ],while negative HUTT patients were received health education.Then 21 -154(42.63 ±27.71) days later,the patients returned to hospital,for the inquiry of symptom improvement,and review of HUTT,24 -hour urine and serum electrolytes.Results (1)The total effective rate of ORS[Ⅰ]treatment was 62.96% (17 /27 cases),while negative conversion rate of HUTT was 48.15% (13 /27 cases).(2)There was no significant difference in serum electro-lytes,24 -hour urine electrolytes or 24 -hour urine volume between HUTT positive group and negative group during the first visit (all P >0.05).(3)In return visit,serum calcium [(2.30 ±0.10)mmol/L vs (2.20 ±0.09)mmol/L,t =2.72,P <0.05]and serum phosphorus [(1.73 ±0.22)mmol/L vs (1.51 ±0.23)mmol/L,t =2.671,P <0.05]in HUTT positive group were significantly higher than those in negative group.The serum sodium,potassium,chloride,mag-nesium and 24 -hour urine electrolytes,24 -hour urine volume had no statistical difference(all P >0.05).(4)24 -hour urine sodium [(159.06 ±72.76)mmol/24 h vs (118.97 ±52.75)mmol/24 h,t =2.712,P <0.05],24 -hour urine chloride [(139.08 ±66.53)mmol/24 h vs (111.34 ±47.33)mmol/24 h,t =2.116,P <0.05]and 24 -hour urine volume [(1 564.21 ±829.39)mL vs (1 058.95 ±509.92)mL,t =3.371,P <0.01]after ORS[Ⅰ]treatment were sig-nificantly higher than those before ORS[Ⅰ]treatment.The serum electrolytes and 24 -hour urine potassium,calcium, phosphorus,magnesium had no statistical difference (all P >0.05).(5)There was no significant difference in serum elec-trolytes,24 -hour urine electrolytes or 24 -hour urine volume between vasovagal syncope group and postural orthostatic tachycardia syndrome group during the first visit(all P >0.05).Conclusions ORS[Ⅰ]treatment can obviously increase the 24 -hour urine sodium,24 -hour urine chloride in children with NMS.ORS[Ⅰ]is an effective therapy for NMS.
