Chinese Journal of Integrated Traditional and Western Medicine 2016;36(1):35-39
OBJECTIVETo observe the expression of peripheral blood CD4+ T lymphocyte apoptosis gene in rheumatoid arthritis (RA) patients with cold dampness type (CDT), and to explore its correlation with clinical indicators of RA.
METHODSSixteen RA patients with CDT (as the RA group) and 16 healthy subjects (as the normal control group) were recruited. CD4 T cell apoptosis rate was detected in the RA group and the normal control group using FCM. mRNA expressions of fas, fasL, caspase-3, caspase-8, bcl-2, and bax were detected using RT-PCR. Correlations between the expression of apoptosis gene and clinical activity indicators of RA (ESR, CRP, RF, CCP, integrals for Chinese medial symptoms, morning stiffness time, joint tenderness number, joint swelling number, DAS28-3) were analyzed.
RESULTSThe apoptosis rate of CD4+ T was significantly lower in the RA group than in the control group [(2. 6 +/- 0.9) % vs. (7.7 +/- 1.3) %, P < 0.01]. mRNA expression levels of fas, fasL, caspase-8, caspase-3, and bax mRNA of CD4+ T significantly decreased, but bcl-2 mRNA expression increased in the RA group (P < 0.01). The apoptosis rate of CD4+ T was negatively correlated with ESR (P < 0.05). The mRNA expression of caspase-8 was negatively correlated with joint swelling number (P < 0.05). The mRNA expression of bcl-2 was negatively correlated with integrals for Chinese medial-symptoms and joint function classification (P < 0.01, P < 0.05).
CONCLUSIONApoptosis obstacle exists in peripheral blood CD4 +T lymphocyte of RA patients, and is closely related to disease activity.

Objective To explore the complications of augmentation mammoplasty by polyacrylamide hydrogel (PAHG) injection and their management.Methods Preoperatively,174 patients underwent breast ultrasound image,and some patients received magnetic resonance imaging (MRI) to ascertain the distribution of injected PAHG.We used the periareolar incision and dissection extended to the subcutaneous tissue,mammary gland,and subgland space.We were able to suck most of the gel by the negative pressure machine and remove the abnormal breast tissue.The secondary breast deformity was repaired with subpectoral placement of silicone mammary implants (48 cases immediately,39 cases secondarily after 3-6 months) according to the individual situation.Results Following-up for 3 to 6 months,most of their symptoms were relieved after removal of the polyacrylamide hydrogel.In the patients who were performed with the implants augmentation mammoplasty,77 cases gained satisfactory results on the shape and texture of the breast (44.3%),and 10 cases were not satisfied with texture of the breast (5.7%).79 cases appeared breast atrophy or flat chest (45.4%).The severe breast deformities occurred in 8 cases (4.6%).Conclusions PAHG should be removed with surgical operation as soon as possible.The open operative technique via periareolar incisions may be a better method for the patients.The breast reconstruction is performed with implants prosthesis for those who are suitable and willing after removal of PAHG.

Objective To explore the methods and significance of section of multiple fibroadeno mas of breast with better incision.Methods From may 2005 to December 2014,21 cases were per formed by removing multiple fibroadenomas of breast with a new incision.Preoperatively,the diag nostic work-up included clinical examination,breast ultrasonography and/or mammography.A new approach,for removing of multiple fibroadenomas of the breast with the incision in periareolar site,was used in our hospital.All palpable breast lumps were excised with this approach through which the fibroadenomas were removed as a whole unit.Then,the breast cavity were irrigated with normal saline solution,and strict haemostasis of the bed was done by electrocautery.If the resulted cavity was larger,interrupted sutures should be performed with the absorbable stitches;otherwise,it was unnecessary.The skin wound was sutured to the deepithelialized area with Vicryl 5-0 (Ethicon).Results There were 21 cases,who underwent surgery using the described technique through which 95 lumps (0.5 cm× 0.5 cm-6.0 cm× 5.0 cm) were removed and included in the study.All patients' resected tumor specimens were pathologically confirmed as fibroadenoma.No major complications were encountered in any of the patients.The incision was well concealed by the dome of the nipple and the areolar pigmented and corrugated skin.Both doctors and patients were satisfied with postoperative aesthetic effect of the incision scar.Conclusions The incision in periareolar site for excision of multiple fibroadenomatas results in minimal scarring and a better appearance than that can be achieved with traditional methods.This technique,which can improve the aesthetic outcome of breast surgery,should be performed when feasible.

A novel oral delivery system that TPGS modified docetaxel proniosomes, DTX-TPGS-PN, was developed and the characterization after hydration was observed. Firstly, Doce-TPGS-PN was optimized by investing the factors, including the type of surfactant, methods of adding TPGS, content of TPGS and the molar ratio of span40/cholesterol, which may affecting the particle size, encapsulation efficiency and instantaneous release of drug in the formulation. Then, the morphology, particle size, Zeta potential, encapsulation efficiency and in vitro release of the formulation were evaluated. The result showed that hydrated nanoparticles of DTX-TPGS-PNs were (93 ± 6.5) nm in size,(-83.95 ± 3.69) mV in zeta potential, (97.31 ± 0.60)% in encapsulation efficiency, exhibiting spherical morphology and biphasic release process that a low burst effect within the first 0.5 hour and a relative-sustained release for the next several hours in PBS. These results indicate the oral delivery system of DTX-TPGS-PN was successfully built with good properties.

Objective To study the effects of marrow mesenchymal stem cells on heart functions and ventricular remodeling after myocardial infarction in rats. Methods Myocardial infarction model was established by ligation of the left anterior descending coronary artery (LAD) in adult SD rats. 4 and 8 weeks after MMSCs implantation, he-modynamic evaluations, left ventricular weight/body weight ratio and heart weight/body weight ratio were determined. HE staining was performed for counting microvasculars and Van Gieson staining was used for measurements and calculation of the myocardial fibrillar collagen. Then we investigated the migration and evolution of MSCs in vivo by fluorescent microscope. Results HR was significantly decreased in transplantation MMSCs group. Eight weeks after transplantation, body weight in transplantation MMSCs group reached that of control group. At the same time, SBP, DBP and MBP were significantly increased in transplantation MMSCs group. HR was significantly decreased in transplantation MMSCs group. Secondly, left ventricular weight/body weight ratio and heart weight/body weight ratio were significantly decreased 4 weeks after transplantation MMSCs. Then the ratio was significantly decreased 8 weeks after transplantation MMSCs. Thirdly density of microvasculars was increased at the boundary of infarction site in the animals transplanted MMSCs. Finally, total volume of the myocardial fibrillar collagen was reduced in the MMSCs treated groups after MI. Conclusion Transplanting MMSCs can improve the ventricular remodeling and heart functions in acute MI rat models.
