Objective To investigate the clinical and pathological features of microscopic thymoma(MT).Methods The histopathological features of 12 cases of MT were observed by histopathologic and immunohistochemical methods.The pathological morphology,diagnosis,and differential diagnosis were discussed combined with literature.Results 6 cases of MT were accompanied by myasthenia gravis(MG) symptoms.Focal hyperplastic thymic epithelial islands were accompanied by large tracts of mature adipose tissue in 12 cases of MTs,and immunohistochemistry showed CK positive.Cyst formation was found in 5 cases,lymphoid hyperplasia in 7 cases,and vascular proliferation in 5 cases.Conclusions MG may be the clinical manifestation of MT.MT can occur in thymic cortex,medulla and cortex and medulla junction.Since the tumor is small and the lesions are multiple,it can not be found by X-ray or CT examination.Diagnosis depends on histopathological examination.Correct understanding of the clinical and pathological features of MT has guiding significance on the treatment and prognosis judgment of MT.Thymic resection was recommended for MG patients either with or without thymoma.

OBJECTIVETo explore the optimized rehabilitation program in the treatment of post-stroke hemiplegia at the recovery stage.

METHODSBased on the randomized controlled principle, 60 patients were randomized into an rehabilita tion + massage group (group A) and an rehabilitation + acupuncture group (group B), 30 cases in each one. Bobath sport therapy and functional training were adopted in the two groups. In the group A, the massage therapy was added. The rolling method and palm-rubbing method were used on the affected side, the pressing, kneading and plucking methods were applied to Jianliao (LI 15), Jianzhen (SI 9), Quchi (LI 11), Huantiao (GB 30), Weizhong (BL 40), Chengshan (BL 57), Zusanli (ST 36) and the other acu points; and the nipping method was adopted at the twelve Jing-well points. In the group B, acupuncture was applied to Baihui (BL 20), Jianliao (LI 15), Quchi (LI 11), Shousanli (LI 10), Huantiao (GB 30), Yanglingquan (GB 34), Jiexi (ST 41) and the other acupoints. The treatment was given once a day, 5 treatments a week in the two groups. The efficacy was evaluated in 3 weeks. Fugl-Meyer scale, Barthel index (BI) score, modified Rankin scale and stroke-specific quality of life (SS-QOL) were used to assess the limb motor function, the activity of daily life (ADL), independent activity of life and the quality of life of the patients in the two groups before and after treatment. Based on the total cost and benefit, the health economics evaluation was conducted in the patients of the two groups.

RESULTSThe treatments all improved the limb motor function (group A: 26.00 (22) vs 37.00 (33); group B: 30.50 (21) vs 39.50 (36)), the independent activity of life, ADL (group A: 43.50 +/- 22.25 vs 57.50 +/- 22.25; group B: 52.83 +/- 16.59 vs 66.67 +/- 12.82) and the quality of life (group A: 122.23 +/- 30.00 vs 145.50 +/- 28.14; group B: 132.43 +/- 23.87 vs 151.47 +/- 22.37) in the patients of the two groups. The differences in all the indices were significant statistically before and after treatment in the two groups (all P<0.05). Above indices after treatment were not different obviously between the two groups (all P>0.05). In terms of health economics, the expense was decreased by RMB 688.48 while BI was increased by every 5 score in group A in comparison with the group B.

CONCLUSIONBoth the rehabilitation and massage therapy and the rehabilitation and acupuncture therapy improve the limb motor function and the quality of life in the patients of post-stroke hemiplegia. The therapeutic efficacies are similar between the two therapeutic programs. The program of rehabilitation and massage is more economical in the aspects of ADL improvement, being advantageous at simple operation and low cost.

Designing of natural product-like compounds using natural products as template structures is an important strategy for the discovery of new drugs. Gambogic acid (GA), which is a Garcinia natural product with a unique caged xanthone scaffold, inhibits potent antitumor activity both in vitro and in vivo. This review summarized the researches on the identification of the antitumor pharmacophore of GA, and the design, structural optimization and structure-activity relationship (SAR) of natural product-like caged xanthones based on it.

Objective To investigate association between gene mutations of surfactant protein C (SP-C) exon Ⅱ and neonatal respiratory distress syndrome(NRDS).Methods From January 2013 to December 2014 in Neonatal Intensive Care Unit of Bayi Children's Hospital Affiliated to Beijing Military General Hospital,a total of 90 cases with NRDS were selected as NRDS group,and they were grouped into 3 subgroups,30 cases in each subgroup.Clinical data were collected by observation figures.A total of 90 cases without NRDS as control group were matched with NRDS group as for the gestational age (GA),gender and birth weight(BW).The study samples were from the clinically diagnosed venous sampling 1 mL,and genomic DNA was extracted with routine technique.After the polymerase chain reaction (PCR) amplification of sequencing was performed.Chromas software and Vector NTI Advanc software were used for analysis,the results were compared with the normal SP-C sequence of GenBank.Results Heterozygous missense mutations included c.115G ＞ T and c.139G ＞ C existed in exon Ⅱ of SP-C gene,which changed protein sequence.GT genotype frequency(0.067) of c.115G ＞T mutation in NRDS group was higher than that(0) in control group (x2 =7.283,P ＜ 0.05).With c.115 G ＞ T gene mutations in patients with NRDS,Ⅲ-Ⅳ grade chest changed and mortality was higher than that of control group.GC genotype frequency (0.067) of c.139G ＞ C mutation in NRDS group was higher than that(0) in control group (x2 =6.207,P ＜ 0.05).Among NRDS group,64 cases of cesarean section patients,GC genotype frequencies were lower than GG genotype frequency (x2 =9.276,P ＜ 0.01),55 cases of patients needed 3-4 PS pulmonary surfactant treatment,GC genotype frequencies were lower than GG genotype frequency (x2 =5.343,P ＜ 0.05).Conclusions Two heterozygous mutations were located in SP-C gene of exon Ⅱ in Chinese Han population of this study.These mutations have never been reported before.c.115G ＞ T of SP-C gene mutation is associated with pathogenesis and severity of NRDS and increases the risk of death in NRDS;while c.139G ＞ C of SP-C gene mutation is associated with pathogenesis of NRDS,but it does not increase the risk of severity and death in NRDS.

Wnt/β-catenin signaling pathway plays an important role in the proliferation, growth, invasion, and metastasis of human cancers. Moreover, β-catenin/T-cell factor 4 (TCF4) interaction regulates the transcription of the key oncogenes in Wnt/β-catenin signaling pathway. Therefore, β-catenin/TCF4 interaction would be a promising therapeutic target for the development of highly selective anticancer agents. At present, most ongoing small-molecule inhibitors targeting β-catenin/TCF4 interaction, including PKF222-815, iCRT3/5/14, LF3, and sanguinarine, have been developed in preclinical studies for human cancer therapeutics. In this review, we summarized the research advances of up-to date inhibitors targeting β-catenin/TCF4 interaction, including the molecular structure and cellular functions of β-catenin in canonical Wnt signaling pathway. This review holds a hopeful avenue for the development of novel and highly selective Wnt inhibitors targeting β-catenin/TCF4 interaction for future anticancer strategy.
