Solid state fermentation involves the growth of microorganisms on moist solid substrates in the absence of free flowing water. It has gained considerable attention of late years due to its several advantages over submerged fermentation. This paper mainly introduces the characteristics and mathematical models of solid state fermentation and summarizes the development situation of various bioreactors, the design standards and applications.

Transient receptor potential vanilloid 3 (TRPV3) is a non-selective cation channel, located on cell membranes. TRPV3 is extensively expressed in various organs such as skin, brain, dorsal root ganglia, heart and colon. It's reported that TRPV3 involves in many physiological processes including sensation, skin barrier formation, hair growth and vasodilatation, and pathological processes like pruritus, cutaneous inflammatory disease and cancer. TRPV3 can respond to innoxious warm stimulation (≥ 33 ‍℃‍), endogenous substances (e.‍g., farnesylpyrophosphate) and exogenous small molecules (e.g., carvacrol, camphor and 2-APB). Recently, several natural or synthetic small molecules (e.g., osthole, 74a and dyclonine) have been shown to suppress TRPV3 activity, accompanying with therapeutic efficacy in animal models of diseases, which suggests the potential of TRPV3 as drug target. This paper reviews the research progress on the structure, physiological functions, related diseases and modulators of the TRPV3 channel to provide theoretical references for the future study on TRPV3 channel.

Aim To investigate the role of ATP-sensi-tive potassium channels-Akt pathway in exogenous hy-drogen sulfide( H2 S) inhibiting the high glucose( HG)-induced injury in H9c2 cardiac cells. Methods The expression level of Akt protein was tested by Western blot assay. The cell viability was measured by cell counter kit-8(CCK-8 assay). The number of apoptotic cells was tested by Hoechst 33258 nuclear staining fol-lowed by photofluorography. The intracellular levels of reactive oxygen species ( ROS ) were detected by DCFH-DA staining followed by photofluorography. Mi-tochondrial membrane potential ( MMP ) was examined by JC-1 staining followed by photofluorography. Results H9c2 cells were treated with 35 mmol·L-1 glucose (high glucose, HG) for 0 ~24 h respectively. After treating for 3 h, the expression level of phosphorated ( p )-Akt protein began to be obviously reduced, the maximum reduced expression level was observed after the cells were exposed to HG for 24 h. Pretreatment of the cells with 50 μmol · L-1 pinacidil ( Pin, a KATP channel opener) or 400 μmol·L-1 NaHS( a donor of H2 S) prior to exposure to HG considerably blocked the down regulation of p-Akt expression level induced by HG. However, pretreatment with 1 mmol · L-1 KATP channel blocker glibenclamide( Gli) obviously attenua-ted the inhibitory effect of NaHS on HG-induced down-regulation of p-Akt expression level. On the other hand, the protective effects of NaHS against the HG-induced cardiomyocyte injury were markedly blocked by 30 μmol·L-1 Ly294002(an inhibitor of Akt), as indicated by the decrease in cell viability and MMP dissipation as well as the increases in the number of apoptotic cells and ROS generation. Conclution KATP channels-Akt pathway mediates the protective effect of H2 S against the HG-induced cardiac injury.

AIM:To analyze the characteristics of optical coherence tomography ( OCT ) in diabetic optic neuropathy ( DON ) retrospectively.
●METHODS:Retrospective study. A total of 175 cases of type ll diabetes with fundus lesions from Dec. 2013 to Dec. 2015 were selected and the clinical information was collected. These cases were diagnosed by consultation between Departments of Ophthalmology and Endocrinology in the Second Affiliated Hospital of Xi′an Jiao Tong University. The results of body examination were recorded and cases were examined by color fundus photography, fluorescein fundus angiography ( FFA) and OCT. All these data were analyzed.
●RESULTS: A total of 49 cases ( 90 eyes, 25. 7%) were diagnosed DON through FFA which manifested abnormal fluorescence in optic papilla. Results of OCT showed:among 90 eyes of DON patients, 15 eyes ( 16. 7%) had normal optic nerve form; 20 eyes(22. 2%) of excavation of optic disc became smaller or disappeared, with prelaminar tissue and peripapillary retinal nerve fiber layer (RNFL) swelling;26 eyes (28. 9%) manifested optic cup deep and cup/disc ratio increasing;18 eyes (20. 0%) had tissue hyperplasia in the hollow or on the surface of optic disc; 11 eyes(12. 3%) had symptoms including vitreous traction optic papilla and optic disc rim rising. DON eyes which had similar fluorescence features could manifest different tissue morph by OCT.
●CONCLUSION: FFA defines DON by change of blood circulation in optic nerve. However, OCT can show differences of tissue morph of optic nerve that FFA fails to do. So OCT can manifest the causes and sites of optic neuropathy more clearly and also provide basis for treatment. The advantages of OCT are conducive to reviews and curative effect tracking among DON patients and these advantages including noninvasive, convenient, inexpensive and repeatable.

AIM:To study whether hydrogen sulfide (H2S) protects H9c2 cardiomyocytes against high glucose ( HG)-induced injury by inhibiting necroptosis .METHODS:The protein levels of RIP3 ( an indicator of necroptosis ) and cleaved caspase-3 were determined by Western blot .The cell viability was measured by CCK-8 assay.The intracellular le-vels of reactive oxygen species (ROS) were detected by 2’, 7’-dichlorfluorescein diacetate staining followed by photofluo-rography.Mitochondrial membrane potential (MMP) was examined by rhodamine 123 staining followed by photofluorogra-phy.The number of apoptotic cells was observed by Hoechst 33258 nuclear staining followed by photofluorography .RE-SULTS:After the H9c2 cells were treated with HG (35 mmol/L glucose) for 0~24 h, the protein expression of RIP3 in the H9c2 cells was significantly increased at 3 h, 6 h, 9 h, 12 h and 24 h, reaching the maximum level at 24 h.Pretreat-ment of the cells with 400μmol/L NaHS (a donor of H2S) or co-treatment of the cells with necrostatin-1 (Nec-1;a speci-fic inhibitor of necroptosis) considerably blocked the up-regulation of RIP3 protein induced by HG.Moreover, pretreatment with NaHS or co-treatment with Nec-1 obviously inhibited HG-induced injuries , leading to an increase in the cell viability , and decreases in the generation of ROS and MMP loss .On the other hand , pretreatment with NaHS also reduced the num-ber of apoptotic cells and the protein level of cleaved caspase-3 in the HG-treated H9c2 cardiomyocytes .CONCLUSION:H2 S protects H9c2 cardiomyocytes against HG-induced injury by inhibiting necroptosis .

Objective To clone and identify the heat shock factors(HSFs)of Schistosoma japonicum and analyze its molec?ular structure and alternative splicing pattern. Methods The New Zealand rabbits were infected with the cercariae of Schistoso?ma japonicum and were killed and dissected 42 days post?infection,and the adult worms of S. japonicum and the livers of the rabbits were harvested. Then,the total RNA was extracted by using Trizol reagent. The Sj?hsf open reading frame(ORF)and the alternative splicing fragments were amplified by RT?PCR from the female,male and egg samples,then cloned and verified by enzyme digestion and sequencing. DNAMAN 8.0,InterPro,Mega 6 combined with the Internet databases were utilized to clarify the gene structure,functional domains,alternative splicing pattern,and the homology and phylogenetic tree of HSFs. Re?sults Sj?hsf ORF and the alternative splicing fragments were amplified from the female,male and egg samples of S. japonicum by RT?PCR. After cloning,the positive recombinant plasmids pBSjHSFf?F,pBSjHSFf?M,pBSjHSFf?E containing Sj?hsf ORF, pBSjHSFs?F,pBSjHSFs?M,pBSjHSFs?E with Sj?hsf alternative splicing fragments were identified by enzyme digestion and se?quencing. Three alternative splicing Sj?hsf isoforms were observed through sequence analysis:Sj?hsf?isoform1(2 050 bp),Sj?hsf ?isoform2(2 086 bp)and Sj?hsf?isoform3(2 111 bp);the GenBank accession numbers were KU954546,KX119143 and KX119144,respectively. All the three isoforms located in the same Contig SJC_S000780 of S. japonicum genome and all ex?pressed at female,male and egg stages,but Sj?hsf?isoform1 with a high?level expression. Sj?HSF?isoform1(671 aa)and Sj?HSF?isoform2(683 aa)had DBD(DNA binding domain),HR?A/B and HR?C domains,while Sj?HSF?isoform3(282 aa)stopped in advance without HR?C domain. Phylogenetic tree analysis of HSFs illustrated that Sj?HSFs belonged to HSF1 family,with a close phylogenetic relationship to Sm?HSFs. Conclusions There are three alternative splicing isoforms of Sj?HSF existing in the female,male and egg stages of S. japonicum,but Sj?HSF?isoform1 expresses in a high?level. This study lays the foundation for further study on molecular mechanisms of Sj?HSFs in regulating the heat shock response system.
