The oxidative stress, inflammatory cytokines and apoptosis have been strongly implicated in the pathogenesis of multiple diseases. Recently, more and more research findings have demonstrated that hydrogen-rich saline (HRS) has the anti-oxidant, anti-inflammatory and anti-apoptotic effects in vivo and in vitro, and can be used to treat multiple diseases, such as ischemia/reperfusion injury, stroke, neurodegeneration, sepsis, neuropathic pain and multiple organ dysfunction syn-drome diseases. This article reviews the possible mechanism of HRS for the treatment of diseases.

Objective To explore the therapeutic effect of infrabrow excision blepharoplasty combined with botulinum toxin A (BTXA) injection on periorbital rejuvenation.Methods A total of 146 females were involved in this study.The incision was designed,hiding at the lower edge of the brow.Eye orbicularis was folded,eyelid lift and some of the skin removed during operation,and simultaneously the shape of eyebrow was better adjusted.After suture cutting,BTXA was injected at the glabella and the lateral of canthus.Results All the 146 cases were followed up for 3 to 12 months.The blepharotosis symptom was improved effectively,the periocular wrinkles were alleviated obviously and no complications occurred in these patients.Conclusions Combining Infrabrow excision blepharoplasty with BTXA injection in periocular treatment is safe,convenient and effective.It is a good clinical approach to make periorbital rejuvenation.

Objective To investigate the protective effects and underlying molecular mechanisms of hydrogen (H2) on high glucose-induced poly (ADP-ribose) polymerase-1 (PARP-1) dependent cell death (PARthanatos) in primary rat Schwann cells. Methods Cultured primary rat Schwann cells were randomly divided into five groups: blank control group (C group), H2 control group (H2 group), high osmotic control group (M group), high glucose treatment group (HG group), and H2 treatment group (HG+H2 group). The cells in H2 group and HG+H2 group were cultured with saturated hydrogen-rich medium containing 0.6 mmol/L of H2, and those in three control groups were cultured with low sugar DMEM medium containing 5.6 mmol/L of sugar, and the cells in HG and HG+H2 groups were given 44.4 mmol/L of glucose in addition (the medium containing 50 mmol/L of glucose), the cells in C group and H2 group were given the same volume of normal saline, and the cells in M group were given the same volume of mannitol. Cytotoxicity was evaluated using lactate dehydrogenase (LDH) release rate assays after treatment for 48 hours in each group. The contents of peroxynitrite (ONOO-) and 8-hydroxy-2-deoxyguanosine (8-OHdG) reflecting oxidative stress injury and DNA damage were detected by enzyme linked immunosorbent assay (ELISA). Poly (ADP-ribose) (PAR) protein expression was analyzed by Western Blot, and immunofluorescence staining was used to determine the nuclear translocation of the apoptosis-inducing factor (AIF). Results The cytotoxicity in HG and HG+H2 groups was significantly increased as compared with that of C group [LDH release rate: (61.40±2.89)%, (42.80±2.32)% vs. (9.92±0.38)%, both P < 0.01], the levels of ONOO- and 8-OHdG were markedly elevated [ONOO- (ng/L): 853.58±51.00, 553.11±38.66 vs. 113.56±14.22; 8-OHdG (ng/L): 1 177.37±60.97, 732.06±54.29 vs. 419.67±28.77, all P < 0.01], and the PAR protein expression was up-regulated (A value: 0.603±0.028, 0.441±0.010 vs. 0.324±0.021, both P < 0.01). The cytotoxicity, the levels of ONOO- and 8-OHdG, and PAR expression in HG+H2 group were significantly lower than those of the HG group (all P < 0.01). There were no significant differences in above parameters between H2 group as well as M group and C group. It was shown by immunofluorescence that AIF was expressed in the cytoplasm in C group, H2 group and M group, AIF was expressed in the whole cell in HG group, and the expression in the nucleus was particularly increased. A small amount of AIF expression was found in the nucleus of HG+H2 group, which indicated that high glucose could promote the AIF nuclear translocation, and that hydrogen-rich medium could prevent the process of translocation. Conclusions High glucose levels could enhance DNA damage that enhance PARthanatos in primary rat Schwann cells. However, H2 can not only reduce DNA damage of injured cells, but also inhibit the special death process, reduce the cell toxicity, all of which have protective effects.

Objective To explore the effective measurements of integrated therapy for the ear keloids in the Oriental. Methods Surgical excision was performed for keloid, and the cut then sutured directly or with flap transfer. At early stage of surgery (within 24 hours), X-ray or electron-ray radiotherapy was used for 3-5 times once daily; and steroids injected after cutting lines at 7th day every two weeks and gradually ended. Results A total of 48 patients were treated, and followed, in which 12 patients were lost of follow-up. The total effective rate was 94. 4 % based on the data of follow-up in 36 patients for 1-3 years. Therefore, the curation rate was 83. 3 % (30 cases) and effective rate 11. 1 % (4 cases). Conclusions Surgical cutting combined with early radiotherapy and steroids injection is the effective integrated therapy for the ear keloids in the Oriental.

With thousands of sequenced 16 S rRNA genes available,and advancements in oligonucleotide microarray technology,the detection of microorganisms in microbial communities consisting of hundreds of species may be possible.The existing algorithms developed for sequence-specific probe design are not suitable for applications in large-scale bacteria detection due to the lack of coverage,flexibility and efficiency.Many other strategies developed for group-specific probe design focus on how to find a unique group-specific probe that can specifically detect all target sequences of a group.Unique group-specific probe for each group can not always be found.Hence,it is necessary to design non-unique probes.Each probe can specifically detect target sequences of a different subgroup.Combination of multiple probes can achieve higher coverage.However,it is a time-consuming task to evaluate all possible combinations.A feasible algorithm using relative entropy and genetic algorithm (GA) to design group-specific non-unique probes was presented.

Humanin (HN, its analogue [Gly14]-Humanin, HNG) was originally identified as an endogenous peptide that protects neuronal cells from apoptosis induced by various types of Alzheimer's disease-related insults. But the relative low content of this peptide in its natural sources limits its further characterization. An expression vector pET32a/HNG was corstructed and transformed it into E. coli BL21 trxB (DE3). HNG was expressed as a fusion protein in the soluble fraction and was purified by nickel affinity chromatography. Subsequently, the purified fusion protein was cleaved by enterokinase and was further purified by reverse-phase HPLC. A 23 mg recombinant HNG (rHNG) from 1 L bacterial culture was purified. The molecular weight of rHNG determined by ESI-MS was 2876.5 Da which was the expected size for correctly processed peptide. The N-terminal amino acid sequence of rHNG determined by Edman degradation method is identical to the theoretical sequence. Neuroprotective bioassay studies of rHNG exhibited its potential neuroprotective effect comparable to that of the natural HNG peptide.

Objective To investigate the methods of rectifying the excessive width of fold line and conglutination of the upper eyelid following blepharoplasty. Methods The width of double eyelid was redesigned, ranging from 6 mm to 8 mm. Then the scar of upper eyelid was excised about 1 mm to 2 mm, and the orbital septum fat flap, orbicularis oculi flap, infraorbicularis oculi fat flap and injection of lipochondria were utilized to fill the depression of upper eyelid. Results In our series, there were 20 eyelids of 16 cases receiving rectification. Orbital septum fat flap was used to correct 2 eye-lids, orbicularis oculi flap 4 eyelids, infraorbicularis oculi fat flap 10 eyelids and injection of lipochon-dria 4 cases. Among 12 eases of following-up, 10 of them were satisfied with the postoperative effects. The results were acceptable in other 2 cases. Conclusion It is a good approach to correct the excessive width of fold line and conglutination of the upper eyelid with local flaps, including the orbital septum fat flap, orbicularis oculi flap, infraorbicularis oculi fat flap and injection of lipochondria.
