Clinicopathological features of congenital hemangioma: a study of 40 cases / 中华病理学杂志

Objective: To investigate the clinical and pathologic features, diagnosis and differential diagnosis of congenital hemangioma (CH). Methods: Forty cases of CH were diagnosed from January 2017 to December 2020 in Henan Provincial People's Hospital. The clinical and pathological and immunohistochemical data were analyzed, with review of literature. Results: There were 24 male and 16 female patients. The lesions were located in the head, neck (11 cases), limbs (14 cases), and trunk (15 cases). The clinical manifestations were congenital painless plaques or masses, the larger ones protruded on the skin surface, mostly dusky purple or bright red, with surrounding white halos. Under low magnification, the tumor was lobular and well demarcated, composed of neo-microvascular lumen of different sizes. The vascular endothelial cells were cuboidal or hobnail in appearance, forming stellar drainage vessels within the lobules. Extra-medullary hematopoiesis was seen in one case of rapidly involuting CH; there were different number of tortuous and dilated vascular lumen between the lobular structures, and some non-involuting CH cases were vascular malformations, which were devoid of lobulated structures. Immunohistochemistry showed that endothelial cells were strongly positive for CD31, CD34 and ERG, while D2-40 and GLUT-1 were negative. Conclusions: CH is a benign congenital vascular tumor with characteristic lobulated growth and abnormal blood vessels in the stroma. Pathological diagnosis often needs to be differentiated from infantile hemangioma, pyogenic granuloma, kaposiform hemangioendothelioma and vascular malformation.

Research progress in integrated diagnosis and treatment platform based on magnetic nanoparticles / 国际生物医学工程杂志

Theranotics, an integrated diagnosis and treatment nanoplatform technology based on nanomaterials, integrates the diagnosis and treatment of diseases seamlessly and shows a broad prospect in medical practice.

Development and research advances of iridoids from Valeriana jatamansi and their bioactivity / 中国中药杂志

Valeriana jatamansi (syn. V. wallichii), a traditional Chinese medicine recorded in Chinese Pharmacopeia (1977 and 2010 edition), has been used for treatment of a variety of conditions including sleep problems, obesity, nervous disorders, epilepsy, insanity, snake poisoning, eye trouble, and skin diseases. Also, it was used as an important substitute for the European V. officinalis, whose root preparation, popularly known as valerian, has been employed as a mild sedative for a long time. In recent years, much attention has been draw to the iridoids, one of the major bioactive constituents of V. jatamansi, leading to the discovery of a series of new iridoids with anti-tumor and neuroprotective activities. Their action machnism also has been discussed. This paper summerized the iridoids and their bioactivities from V. jatamansi in recent years, which could provide basic foundation for development and research of V. jatamansi.

Nutrition Factors Influence the Production of Insecticidal Crystal Proteins Cry1 and Cry2 from Bacillus thuringiensis 4.0718 / 微生物学通报

In order to increase the production of insecticidal crystal proteins Cry1 and Cry2, firstly, Plack-ett-Burman design was applied to evaluate the effectiveness of the related nutrition factors; it was found that the soybean powder and MnSO4?H2O were significant factors for Cry1 production, but the yield of Cry2 wasn’t effected remarkably in such medium. Then the steepest ascent experiment was adopted to approach the optimal region of the medium composition. Lastly, the optimal concentration of the soybean powder and MnSO4?H2O was 11.5 and 0.02 g/L, obtained by response surface methodology (RSM). The final yields of Cry1 and Cry2 was 0.32 mg/mL and 0.11 mg/mL, increasing twice more than that in the medium optimized before. The median lethal concentration (LC50) of optimal medium was 1.09 ?L/mL. The toxicity to Heli-coverpa armigera was significantly enhanced than the old one.

Application of both expanded cutaneous flap and temporoparietal fascia flap in ear reconstruction with Medpor framework / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the feasibility and results of application of both expanded cutaneous flap and temporoparietal fascia flap in total ear reconstruction with Medpor framework.</p><p><b>METHODS</b>The main procedure consists of two stages: Stage I-skin expansion; Stage II -auricle formation consists of orientation of Medpor implant and creation of coverage for the implant by both expanded skin flap and temporoparietal fascia flap.</p><p><b>RESULTS</b>Twenty-two ears in 22 unilateral microtia patients were constructed using Medpor implants covered with both expanded cutaneous flap and temporoparietal fascia flap over the last three years, they were accepted as pleasing by the patients.</p><p><b>CONCLUSIONS</b>Application of both expanded cutaneous flap and temporoparietal fascia flap can assure no extrusion of Medpor implant in ear reconstruction. Either more, the two layers of transferred tissues will not affect the profile details of the reconstructed ear.

Cloning and superexpression of cry1Ac gene from 20kb DNA associated with Bacillus thuringiensis Cry1A Crystal Protein / 生物工程学报

The CrylA Crystal Protein from Bacillus thuringiensis is associated with DNA, but the role and sequences of these DNA molecules are unknown. CrylA bipyramidal crystals from B. thuringiensis strain 4.0718 was selectively dissolved and associated DNA was extracted from protoxin. The DNA was digested with Nde I to obtain 3 to 5 kb fragments and then the fragments were subcloned into pMD18-T vector, screening of recombinants were done by PCR-RFLP and sequencing. The ORF of cry1Ac gene was amplified by primers designed and then subcloned. The 3.5 kb BamH I and Sal I fragments of pMDX35 was inserted into the pET30a vector, giving 8.9 kb recombinant plasmid, pETX35. ETX35 strain were obtained by transformed pETX35 into B121 (DE3). A 141 kD fusion protein was superexpressed as inclusion bodies. Quantitative protein analysis indicated that the amount of 141 kD protein was above the level of 51.36% of total cellular protein. Plasmid pHTX42 constructed from shuttle vector pHT304 was transformed B. thuringiensis acrystalliferous strain XBU001 with electroporation to obtain the recombinant HTX42. The recombinant protein was found with a molecular mass of 130 kD on sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Scanning analysis indicated that the expressed protein accounted up to 79.28% of total cellular proteins and accumulated in the cells mounted up to 64.13% of cellular dry weight. Under Atomic Force Microscopy (AFM), typical bipyramidal crystals from HTX42 strain were found with a size of 1.2 microm x 2.0 microm. Bioassay showed that these inclusion bodies of ETX35 strain and crystals from HTX42 strain were highly toxic against the larvae of Plutella xylostella. On such a base, constructing insecticidal recombinant and analyzing the source, structure, and function of the 20 kb DNA can be further achieved.
