Objective To investigate the influence of early hyperbaric oxygen (HBO) therapy on cerebral edema and neural function in patients after minimally invasive surgery for intracerebral hemorrhage (ICH).Methods A random number table was used to divide 148 ICH surgery patients into a control group (n =75) and a treatment group (n =73).In the treatment group,HBO was administered in 51 cases 6-24 hours after surgery and then once a day for twenty days.Cerebral edema volume was measured by brain CT before the operation and on the 3rd,7th,14th and 21st day after the surgery.Neurological impairment was scored at the same time points.Results Average cerebral edema volume was significantly smaller in the treatment group than in the control group on the 7th,14th and 21st days,but not on the 3rd day.The neurological impairment scores (NIS) after therapy were significantly lower than that before therapy in both groups.The two groups' average scores were not significantly different before the operation or on the 3rd day,but they were significantly lower in the treatment group thereafter.Conclusion Early HBO therapy can significantly reduce cerebral edema and contribute to nerve functional recovery in patients after minimally invasive ICH surgery.

AIM: To observe the effects of scleral buckling surgery for retinal detachment under microscope and under indirect ophthalmoscope.
METHODS: Forty - six patients ( 46 eyes ) with rhegmatogenous retinal detachment were retrospectively analyzed. Twenty-six patients received surgeries under microscope was retrospectively analyzed and compared to that of 20 patients who received surgeries under indirect ophthalmoscope by the same operator.
RESULTS: No statistical difference was found in patients' operation method choice, including condensation reaction reattachment situation and the retina reset operation at a time ( P> 0. 05 ). The best corrected visual acuity of microscopic group after 1mo of operation was better than before operation, and the improving rate of vision after operation was higher than that of the traditional group (P<0. 05).
CONCLUSION:The curative effect of external approach microsurgery has the similar efficacy with the conventional external approach surgery, and gets better visual acuity.

? AlM: To analyze the reason of corneal epithelial implantation and ingrowth after laser in situ keratomileusis ( LASlK ) , and summarize the treatment experiences.
?METHODS: The clinical data of postoperative corneal epithelial ingrowth on 18 cases (30 eyes) from 1 256 cases (2 256 eyes) after LASlK were retrospectively analyzed in our hospital from January 2008 to December 2012. After the treatment of all eyes, patients’ general visual quality scores before and after treatment were analyzed.
?RESULTS:There were 18 cases ( 30 eyes ) with corneal epithelial implantation and ingrowth after LASlK, and the incidence rate was 1. 3%. ln the 18 cases (30 eyes), there were 12 eyes corneal flap epithelial ingrowth caused by postoperative trauma, 12 eyes caused by multiple corneal flap flush, 2 eyes caused by intraoperative irregular corneal flap, and nothing special for 4 eyes. The classification of corneal epithelial ingrowth of 30 eyes:grade I, 11 cases (18 eyes);gradeII, 4 cases (8 eyes);grade Ⅲ, 3 cases ( 4 eyes ) . Grade I-II were treated with TobraDex eye drops and intraocular pressure lowering drug. Grade Ⅲ firstly were treated by drugs, otherwise by surgery if it didn’t improve. After treatment, 8 cases (13 eyes) epithelial ingrowth disappeared from 11 cases ( 18 eyes ) , 3 cases ( 5 eyes ) implanted epithelial tumor shrank in grade l;epithelial implantation of 2 cases (4 eyes) in grade II disappeared, implantation degree of 2 cases (4 eyes) reduced to grade I;2 cases (2 eyes) in grade Ⅲ had 0. 5 ~ 1mm wide flap edge shallow gray ribbon 1 mm inside the limbus, visual acuity was 0. 8 ~1. 2, 1 case ( 2 eyes ) treated with curettage corneal epithelial implantation and endophytic epithelium hadn’t relapsed in the follow-up. After the treatment, 18 cases of corneal epithelial ingrowth got lower visual quality scores than those before therapy (Hc=10. 511, P<0. 01).
?CONCLUSlON: Operation standardized, postoperative early detection and aggressive treatment are important for prevention and treatment of complications after LASlK.

OBJECTIVETo investigate the effect and mechanism of Bufei Qingyu Granule (BQG) in mollifying the skin of scleroderma model mice.

METHODSScleroderma model induced with bleomycin in BALB/C mice 8-weeks old were administered with different dose of BQG for 26 days. The pathological changes of the mice skin were observed.

RESULTSTreatment with low, medium and high dose of BQG showed a tendency to ameliorate the thickened dermis in scleroderma mice but without statistical significance. Medium and high dose of BQG reduced the perivasculitis of dermis and alleviated the reduction or deletion of accessory structure, such as hair follicle and sweat gland. And the spleen index was lower markedly in mice treated with BQG of any dose than that in the untreated model mice (P < 0.05).

CONCLUSIONBQG could ameliorate the sclerosed skin in model mice and prevent the occurrence of splenomegaly.

Objective To observe the impacts of different storage temperatures on the activities of adipose tissues and the extraction and proliferation of adipose-derived stem cells (ADSCs) situated in harvested fat.Methods Adipose tissues obtained by liposuctions in healthy females were kept in different temperature;all groups of adipose tissues were studied in context of the histomorphology and activity of GAPD as well as the extraction efficiency and proliferation of ADSCs.Results Adipose tissues cryopreserved at 4 ℃ within 24 hours could retain their activities effectively,but their activities would decrease rapidly if they preserved at room temperature.The efficiency of adipose tissues extracting stem cells and their proliferations were affected by storage temperatures and times.If adipose tissues were preserved at room temperature for over 1 hour,the extraction efficiency and proliferation of their ADSCs would be lower significantly.Conclusions Adipose tissues cryopreserved at 4 ℃ can effectively ensure their activities and their extraction efficiency and proliferation of ADSCs.It is important to preserve adipose tissues at low temperature after harvesting fat graft.

Codon usage bias is an important characteristic of genetic information transfer in organisms. Analysis of codon usage bias of different species is important for understanding the rules on genetic information transfer. The previous method for analysis of codon usage bias is mainly based on genomic data. However, this method is greatly limited, because the genome sequences of higher organisms are still not available up to now. In this study, we found that we could obtain the same optimal codons of Ganoderma lucidum (Curtis: Fr.) P. Karst based on its whole genomic data or large-scale transcriptomic data from its liquid-cultured hyphae, primordium and fruiting body, separately. This result indicated the feasibility to understand the codon usage bias based on the large-scale transcriptomic data. By calculating the proportion of rare codons of Escherichia coli and Saccharomyces cerevisiae in 26 terpene synthases (TS) of G. lucidum, we found that the rare codons of S. cerevisiae have a higher proportion in TS genes, while the rare codons of E. coli have relatively lower, suggesting that the TS genes of G. lucidum are possibly more difficult to be expressed in S. cerevisiae than in E. coli. Chemical synthesis of TS genes according to the yeast optimal codons will be an effective way to solve the problem on the mismatch of gene codon bias between the foreign genes and the host strain.

Background Previous experimental and clinical studies have proved that elevated serum uric acid increased risk for developing hypertension.Whereas,there are a paucity of information on the relationship between serum uric acid and prehypertension.Objective The purpose of this research is to evaluate the association between the serum uric acid and prehypertension.Method A cohort of seven thousand eight hundred thirty-nine subjects without hypertension and other cardiovascular diseases were recruited from a cross sectional study in urban and rural place in 9 provinces during 2005-2006.Based on serum uric acid(324 ?mol/L for overall population,366 ?mol/L for male,285 ?mol/L for female),people were categorized into quartiles.The odds ratio for prehypertension was calculat ed with the lowest quartile as the reference.Results The prevalence of prehypertension increased with increasing uric acid in total population(P324 ?mol/L)to lowest quartile 1(

Objective To evaluate the feasibility and the clinical value of extraperitoneal laparoscopic radical prostatectomy in treatment of localized prostate cancer.Methods Clinical data of 26 patients with localized prostate cancer treated with extraperitoneal laparoscopic radical prostatectomy were analyzed retrospectively.All patients were pathologic diagnosed with prostate cancer by preoperative prostate biopsy or transurethral resection of prostate surgery.Gleason grade was from 6-8.Results Twenty-six operations were successfully accomplished ,without converting to open approach.The operative time was 120-270 min(mean was 165 min) ,the intraoperative blood loss was 180-650 ml (mean was 320 ml) ,indwelling catheter time 12-19 d (mean was 14 d).There were 6 cases with little uroclepsia, satisfactory with urination after contract urethral sphincter for 1-3 Months.Pathologically confirmed all prostate cancer;2 cases of positive margins after surgery plus endocrine therapy.All the cases were followed up from 2 to 36 months.The biochemical recurrence was 5 cases who had undergone endocrine therapy.Conclusion Extraperitoneal laparoscopic radical prostatectomy is a safe and feasible procedure with little trauma, small bleeding and fast recovery which is well worth popularizing.Replace open surgery may become frist choice therapeutic method for localized prostate cancer.

Objective To evaluate the predicting value of the marker of endothelial injury: plasma matrix metalloproteinase-9( MMP-9) and high sensitivity C-reactive protein( hsCRP) level on the progression of acute anterior circulating territory infarction progressing to malignant middle cerebral artery infarction (m-MCAI). Methods 90 patients with acute anterior circulating territory infarction, in which 46 patients progressed to m-MCAI, were collected and sampled consecutively. The plasma MMP-9 and hsCRP of all patients were determined by ELISA and immunotur-bidimetry,respectively,at admission. And the clinical characters and cranial CT features of the patients were analyzed. Results At admission,the plasma MMP-9 level in the patients with m-MCAI(242.0 ±58.0)ng/ml was significantly higher than that in the patients with non m-MCAI( 169.0 ± 50.0) ng/ml( P < 0. 01) ,the plasma hsCRP level in the patients with m-MCAI(6.25 ±1.2) ng/ml was significantly higher than that in the patients with non m-MCAI( 1.55 ± 0.9) mg/ml( P <0. 01).Conclusion The increased level of plasma MMP-9 and hsCRP could be predictors for the m-MCAI proceeding.
