Objective Cavernous hemangioma of infant was reported as an obscure diagnosis with the different sensitivity to corticosteroid therapy and various natural courses. Therefore, a clinical studies for the biological classification of deep subcutanious vascular lesions might be needed, which was alluded by Mulliken two decades ago. Methods Infants with cavernous hemangiomas accepted normal system corticosteroid therapy during the first 6 months of life before eight-year-follow-up, which continued until the children were 9 to 10 years old. The expression of PCNA and bFGF, and cellular histological characteristics were observed in 12 cases by biopsy. Results There were two major categories of subcutaneous vascular lesions groups: deep capillary hemangiomas, a lesion regressing slowly, and venous malformation, a lesion growing commensurated with the child. They will be also distinguished on the basis of diverse final treatment results, expression of cellular markers, microscopical characteristics, and physical signs. Conclusion The new classification appears to be helpful to make the choice of therapy for infants with "cavernous hemangiomas" , which is proven to be a terminologic confusion.

Objective To investigate change of chemokine mRNA and protein in the patients with diabetes mellitus(DM)complicated infection.Methods Fourty-eight patients with DM complicated infection were studied.Expression of mRNA and protein of monocyte chemoattractant protein-1(MCP-1)and interleukin 8 (IL-8)were measured by FQ-PCR,RT-PCR and ELISA.The relationship between hs-CRP,PMNL,IL-8 and MCP-1 were analyzed.Results Expression of mRNA and protein of MCP-1 and IL-8 were increased in the DM patients complicated infection.MCP-1 mRNA(mesured by FQ-PCR)was positively correlated with the protein(IL-8 r = 0.33;MCP-1 r = 0.88;P

Flavonoids is one of the biggest families of the plant-derived secondary metabolites with structural diversity. Until now, over 10 000 kinds of flavonoids with distinct structures have been purified and identified from plants, and some of them possess a range of important pharmacological effects, such as anticancer, anti-inflammatory and so on. So far, a number of genes and enzymes responsible for the biosynthesis of flavonoids have been reported, especially, a great of progress has been achieved in the synthetic biology of flavonoids in the recent years. Herein, based upon a brief introduction on the biosynthesis of flavonoids, this review summarizes the research advances in synthetic biology of flavonoids in the past two decades (2001-2021), highlighting the cell factories construction of the representative flavonoids. And, a brief discussion and prospects of the relevant metabolic bottlenecks and optimizing strategies are proposed.

OBJECTIVETo investigate the effcacy of the staple fixation for the treatment of hamate metacarpal joint injury.
METHODSFrom May 2009 to November 2012,16 patients with hamate metacarpal joint injury were treated with staple fixation including 10 males and 6 females with an average age of 33.6 years old ranging from 21 to 57 years. Among them, 11 cases were on the fourth or fifth metacarpal base dislocation without fractures, 5 cases were the fourth or fifth metacarpal base dislocation with avulsion fractures of the back of hamatum. Regular X-ray review was used to observe the fracture healing, joint replacement and position of staple fixation. The function of carpometacarpal joint and metacarpophalangeal joint were evaluated according to ASIA (TAM) system evaluation method.
RESULTSAll incision were healed well with no infection. All patients were followed up from 16 to 24 months with an average of (10.0 +/- 2.7) months. No dislocation recurred, the position of internal fixator was good,no broken nail and screw withdrawal were occurred. Five patients with avulsion fracture of the back of hamatum achieved bone healing. The function of carpometacarpal joint and metacarpophalangeal was excellent in 10 cases,good in 5 cases, moderate in 1 case.
CONCLUSIONThe application of the staple for the treatment of hamatometacarpal joint injury has the advantages of simple operation, small trauma, reliable fixation, early postoperative function exercise and other advantages, which is the ideal operation mode for hamatometacarpal joint injury.

The 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) catalyzes the conversion of HMG-CoA to mevalonate in mavalonic acid pathway, which is the first committed step for isoprenoid biosynthesis in plants. However, it still remains unclear whether HGMR gene plays a role in the isoprenoid biosynthesis in Dendrobium officinale, an endangered epiphytic orchid species. In the present study, a HMGR encoding gene, designed as DoHMGR1 (GenBank accession JX272632), was identified from D. officinale using the reverse transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE) methods, for the first time. The full length cDNA of DoHMGR1 was 2 071 bp in length and encoded a 562-aa protein with a molecular weight of 59.73 kD and an isoelectric point (pI) of 6.18. The deduced DoHMGR1 protein, like other HMGR proteins, constituted four conserved domains (63-561, 147-551, 268-383 and 124-541) and two transmembrane motifs (42-64 and 85-107). Multiple sequence alignment and phylogenetic analyses demonstrated that DoHMGR1 had high identity (67%-89%) to a number of HMGR genes from various plants and was closely related to Vanda hybrid cultivar, rice and maize monocots. Real time quantitative PCR (qPCR) analysis revealed that DoHMGR1 was expressed in the three included organs. The transcripts were the most abundant in the roots with 2.13 fold over that in the leaves, followed by that in the stems with 1.98 fold. Molecular characterization of DoHMGR1 will be useful for further functional elucidation of the gene involving in isoprenoid biosynthesis pathway in D. officinale.
