Given the myriad of choices available on the market, selecting the appropriate wound dressing remains a challenge for most healthcare workers. It is important to exercise discretion and adopt a systematic approach in dressing selection following wound assessment, as this will directly impact on rates of wound healing, which in turns affects the patient’s quality of life and overall healthcare costs. This paper provides an overview of the common types of wound dressings in use currently and gives a brief synopsis of some of the latest advances in wound care technology and their applications in management of complex wounds. The consensus to date is for the use of hydrogels in the debridement stage, foams and low-adherence dressings in the granulation stage and hydrocolloids and low-adherence dressings for the epithelialization stage. Additional studies and research need to be undertaken to further evaluate the application of advanced wound technology in clinical practice.

This study investigated the relationship among the severity of hearing impairment,vestibular function and balance function in patients with idiopathic sudden sensorineural hearing loss (ISSNHL).A total of 35 ISSNHL patients (including 21 patients with vertigo) were enrolled.All of the patients underwent audiometry,sensory organization test (SOT),caloric test,cervical vestibular-evoked myogenic potential (cVEMP) test and ocular vestibular-evoked myogenic potential (oVEMP) test.Significant relationship was found between vertigo and hearing loss grade (P=0.009),and between SOT VEST grade and hearing loss grade (P=0.001).The abnormal rate of oVEMP test was the highest,followed by the abnormal rates of caloric and cVEMP tests,not only in patients with vertigo but also in those without vertigo.The vestibular end organs were more susceptible to damage in patients with vertigo (compared with patients without vertigo).Significant relationship was found between presence of vertigo and SOT VEST grade (P=0.010).We demonstrated that vestibular end organs may be impaired not only in patients with vertigo but also in patients without vertigo.The cochlear and vestibular impairment could be more serious in patients with vertigo than in those without vertigo.Vertigo does not necessarily bear a causal relationship with the impairment of the vestibular end organs.SOT VEST grade could be used to reflect the presence of vertigo state in the ISSNHL patients.Apart from audiometry,the function of peripheral vestibular end organs and balance function should be evaluated to comprehensively understand ISSNHL.Better assessment of the condition will help us in clinical diagnosis,treatment and prognosis evaluation of ISSNHL.

Objective:This study examined the associations between the levels of bile acids in early pregnancy and the occurrence of overweight.Methods:From 2010 to 2012, 22 302 pregnant women were recruited by Tianjin Women and Children′s Health Center to investigate gestational diabetes. Two hundred and forty-three women with gestational diabetes mellitus provided overnight fasting blood samples in the first trimester, and 243 counterparts without gestational diabetes mellitus matched on age were selected randomly to establish a nested case-control study. The association between bile acids and overweight were evaluated by binary logistic regression with data from 166 overweight pregnant women (body mass index≥24.0 kg/m 2) and 320 normal weight subjects (body mass index <24.0 kg/m 2). Results:Compared to non-overweight group, the level of primary unconjugated bile acids in overweight group was significantly higher. After adjustment of confounding factors, the OR of cholic acid (CA)>0.086 nmol/mL for overweight was 2.09 (95% CI 1.14-3.80, adjusted P=0.040), and OR of chenodeoxycholic acid (CDCA)>0.043 nmol/mL was 2.15 (95% CI 1.22-3.78, adjusted P=0.040) compared with the lower groups. However, the significant associations between the other bile acids and overweight were not detected. Stepwise selection was used to identify significant bile acid species in logistic regression. We found that only CA was independently associated with overweight, and the OR of CA>0.086 nmol/mL vs≤0.086 nmol/mL was 2.03 (95% CI 1.11-3.74, P=0.022). Conclusion:CA and CDCA in early pregnancy maybe associated with overweight, and CA might be independently associated with overweight.

Objective:To discuss the pathological relationship between P33ING1 and stomach cancer and its clinical significance. Methods: In 71 cases of stomach cancer specimen, twelve cases of gas tric mu cous membrane atypical hyperplasia tissues and 18 cases of normal gastric mucous membrane tissue（as control）,the expression of P33ING1 were detected b y EnVision immunohistochemical method,while the expression of P53 and Bcl -2 in stomach cancer were also detected. Results: P33IN G1 expression in mucous membrane atypical hyperplasia group and control group was positive, the expression in stomach cancer group was extremely low(62.0%，44 /71), significantly different from the other 2 groups(P<0.01).P33ING1 expression in stomach cancer was related to the tumor growth, lymph node meta s tasis and tumor polarization (P<0.01), P53 expression was related to tumor s ize, growth and lymph node metastasis (P<0.01). Bcl-2 expression was relate d to lymph node metatasis and tumor polarization.The expression of P33ING1 was related to that of P53 in stomach cancer(P<0.05),while had no relation with that of Bcl-2.Conclusion:P33ING1 may play an importa nt role in the occurrance and development of stomach cancer.It's very important to detect the expression of P33ING1 and P53 simultaneously.

OBJECTIVETo compare the clinical characteristics of three subcategories of laparoscopic hysterectomy: total laparoscopic hysterectomy (TLH) and two subcategories of laparoscopic-assisted vaginal hysterectomy (LAVH): LAVHs and LAVHb.

METHODSWe retrospectively analyzed the clinical data of 393 patients underwent laparoscopic hysterectomy, including TLH (n=178), LAVHa (n=177), and LAVHb (n=38), in our hospital from September 2002 to September 2005.

RESULTSMyoma and adenomyosis of uterus were the most common diseases in this study, accounting for 66.9%, 38.4%, and 52.6% in TLH group, LAVHa group, and LAVHb group, respectively. The mean surgery duration and blood loss were not significantly different between TLH group and LAVHa group (P > 0.05), but were significantly less in TLH group than in LAVHb group (P < 0.05). The bulk of uterus in TLH group was significantly bigger than in other two groups (P < 0.05). The incidence of major complications in the TLH group (9. 0%) was lower than in LAVHa group (14.1%) and in LAVHb group (18.4%), but without statistical significance. Conclusion Compared with LAVH, TLH is feasible to deal with bigger uterus with less blood loss and shorter surgery duration and without more frequent complications.

OBJECTIVETo investigate the effect of recombinant human hepatopoietin (rhHPO) and partial hepatectomy on rapidly induced expression of immediate early gene.

METHODSWe investigated the different gene expression within 1 hour after 2/3 partial hepatectomy by representational difference analysis and in primary cultured hepatocytes system.

RESULTSIn the expressed sequence tag (EST) library, we identified that most of these genes were immediate early gene, and found one new gene PC3 that might be associated to liver regeneration in the EST library. Moreover, PC3 gene was rapidly induced after 2/3 partial hepatectomy and the expressing peak was within 1~2 hours after operation. HPO can rapidly induce the expression of these genes (c-fos, LRF-1, and PC3, etc.) in primarily cultured rat hepatocyte, which might be one of HPO molecular mechanism on stimulating hepatocyte proliferation.

CONCLUSIONSrhHPO and partial hepatectomy can rapidly induce the expression of immediate early gene. PC3 gene is immediate early gene related to liver regeneration.

Objective:To observe the effect of pressure therapy on the formation of hypertrophic scars(HTS) and transforming growth factor beta 1 (TGF-β1) / Sma and Mad homolog proteins (Smad) signaling pathway.Methods:Twelve adult healthy New Zealand white rabbits(provided by the Animal Experiment Center of the Air Force Military Medical University) were wounded with 1 cm round punch on 4 sites of the ventral side of each ear. Round scalpels were used to make incisions along the marked lines, dissect the skin and perichondrium. The remaining tissue was scraped off to expose the wound surface. Scar formation was observed on the 28th day after surgery. After the establishment of rabbit ear HTS models, the right ears were used as self-controls, while the left ears were set as the experimental group. Two hypertrophic scars were randomly selected from each rabbit ear, 24 per group. Experimental group: 4-0 nylon silk thread was used to sew the pressure pad on the circular NdFeB magnets pad with a diameter of 1.5 cm to the rabbit ear cartilage. Flexiforce pressure sensor was used to measure the pressure, and the pads were adjusted to maintain a pressure of 20-25 mmHg (1 mmHg=0.133 kPa) for more than 23 h per day. Control group: no treatment. On the 40th day of pressure therapy, the general morphology of rabbit ear scars were observed, and the tissues were harvested for hematoxylin and eosin (HE) staining and Masson’s Trichrome staining for histological study. The scar elevation index (SEI), the number of fibroblasts, and the thickness of the stratum corneum were calculated. The relative mRNA expression levels of TGF-β1, Smad3, collagen type (Collagen )Ⅰ, Collagen Ⅲ, α-smooth muscle actin (α-SMA) were measured with qPCR; Western blotting was used to detect the relative protein expression levels of TGF-β1, Collagen Ⅰ, Collagen Ⅲ, α-SMA and the phosphorylation level of Smad3 (the ratio of p-Smad3 and Smad3 proteins). Statistical analysis was performed with Excel 2019 and GraphPad Prism 8.0. The measurement data conformed to normal distribution and was expressed as Mean±SD. Student’s t-test was used for the comparison between two groups. P<0.05 was considered statistically significant. Results:A total of 96 wounds were formed in 12 rabbits, 27 wounds had no obvious hyperplasia, and the remaining 69 wounds formed hypertrophic scar tissue blocks with a prominent skin surface, firm texture, and dark red appearance. The scars formation rate was 71.9% (69/96). On the 40th day after the application of pressure, the scars in the experimental group were significantly reduced, softer, and the color was slightly lighter compared with the control group. The results of HE staining and Masson’s Trichrome staining showed that the thickness of the stratum corneum, SEI, and the number of fibroblasts were (69.33±6.03) μm, 1.30±0.08, and (236.30±14.64) cells/field, respectively, which were significantly lower than those in the control group [(114.00±10.15) μm, 1.72±0.05, (320.30±14.57) cells/field] (all P<0.01). Abundance in capillaries, inflammatory cells, and fibroblasts were not observed in the dermal layer. The collagen fibers were orderly arranged and sparse. The results of fluorescence quantitative PCR showed that the relative expression levels of TGF-β1, Smad3, Collagen Ⅰ, Collagen Ⅲ, and α-SMA mRNA in the experimental group were 0.48±0.08, 0.58±0.05, 0.04±0.01, 0.15±0.02, 0.31±0.03, respectively, lower than those of the control group(1.00±0.07, 1.00±0.05, 1.00±0.08, 1.00±0.10, 1.00±0.06) (all P<0.01). The results of Western blotting showed that the relative protein expression of TGF-β1, Collagen Ⅰ, Collagen Ⅲ, α-SMA and the phosphorylation level of Smad3 in the experimental group were 0.65±0.03, 0.07±0.01, 0.43±0.03, 0.53±0.03, 0.54±0.03, all lower than the control group’s 1.02±0.06, 0.93±0.05, 0.92±0.03, 0.82±0.03, 0.92±0.03 (all P<0.01). Conclusions:Pressure therapy can significantly inhibit the hyperplasia of scars, improve the structure of HTS tissue, facilitate the normal arrangement of collagen fiber, and reduce the excessive deposition of collagen. Pressure therapy may inhibit scar proliferation by regulating the TGF-β1/Smad signaling pathway.
