  • Clinical Significance and Expression of the Human Telomerase Gene in Cytological Specimens of Cervix

    【摘要】 目的 探讨宫颈上皮内瘤变(CIN)和宫颈鳞癌(SCC)组织中人类染色体端粒酶基因(hTERC)的表达和临床意义。 方法 收集2007年10月-2009年6月经病理学证实的116例宫颈脱落细胞标本,其中LSIL(CINⅠ)30例、HSIL(CINⅡ/Ⅲ)37例、SCC 16例、宫颈炎33例,用荧光原位杂交(FISH)方法检测脱落细胞hTERC基因。 结果 在宫颈炎、LSIL、HSIL和SCC组中hTERC基因的表达率分别是6.1%、16.7%、51.4%和93.8%,其中,HSIL、SCC组与宫颈炎组比较,hTERC基因阳性率差异有统计学意义(Plt;0.05),LSIL组与HSIL组比较、LSIL组与SCC组比较、HSIL组与SCC组比较,差异有统计学意义(Plt;0.05),且随着病变程度增加,hTERC基因表达率增加。 结论 hTERC基因在细胞学LSIL、HSIL和SCC中表达异常,且随病变程度增加阳性表达率也增加,可作为宫颈癌癌前病变进展的生物遗传学监测指标,并有望成为宫颈癌早期筛查方法之一。【Abstract】 Objective To explore the clinical significance and expression of the human telomerase gene (hTERC) in the cervical intraepithelial neoplasia (CIN) and squamous carcinoma of the cervix (SCC). Methods According to histological biopsy from October 2007 to June 2009, 116 pap smears were divided into LSIL (n=30), HSIL (n=37), SCC (n=16), and cervicitis (n=33) groups. Fluorescence in situ hybridization (FISH) was used to detect the expression of hTERC. Results Positive expression rate of hTERC was 6.1% in cervicitis group, 16.7% in LSIL group, 51.4% in HSIL group, and 93.8% in SCC group, respectively. Compared to cervicitis group, the expression of hTERC in HSIL and SCC groups was significantly higher (Plt;0.05). Among LSIL, HSIL, and SCC groups, there were significant differencec in hTERC expression between every two groups (Plt;0.05). From LSIL to SCC, the expression of hTERC increased obviously. Conclusion Abnormal expression of hTERC exists in LSIL, HSIL, and SCC patients, which significantly increases during malignant development. It may be a biogenetics monitor index of cervical precancerosis and will be a screening marker for cervical cancer.

  • Research on the Application of 10% Sodium Chloride for Stage-Ⅲ Pressure Ulcer Debridement

    ObjectiveTo explore the application of 10% sodium chloride for stage-Ⅲ pressure ulcer debridement. MethodsAccording to the standard, 68 stage-Ⅲ pressure ulcer cases were selected from January 2011 to December 2014. All the patients had yellow surface and positive bacterium cultivation suggesting wound infection. They were randomly divided into control group and trial group. The control group used traditional treatment for debridement, while the trial group used 10% sodium chloride, until the end of debridement where the granulation became fresh and bacterium cultivation negative. Then we compared these two groups in terms of debridement time, wound drainage, wound smell, granulation growth, pain score and cost. ResultsThe control group debridement time was 18-32 days, averaging (22.4±10.8) days, and the trial group debridement time was 5-13 days, averaging (11.6±4.0) days (P<0.05). The control group wound drainage ratings score was 6.70±2.87, while the trial group wound drainage ratings score was 3.65±1.23 (P<0.05). In terms of the wound smell, the control group had a score of 2.74±1.62, and the score for the experimental group was 1.26±0.51 (P<0.05). The average cost of the control group was (975.00±10.29) yuan, while the experimental group was (626.00±8.18) yuan (P<0.05). ConclusionThe application of 10% sodium chloride for stage-Ⅲ pressure ulcer debridement can shorten debridement time, promote the growth of granulation and reduce the economic burden, which is worth clinical promotion.

  • Retrospective analysis of wound outpatient cases from a tertiay hospital of Leshan City

    ObjectiveTo explore the epidemiological characteristics and analyze the related diagnosis and treatment information of wound outpatient cases in a tertiay hospital in Leshan City.MethodsThe data of cases admitted to the wound clinic in a tertiary hospital of Leshan City between January 1st, 2017 and December 31st, 2019 were retrospectively collected. The SPSS software was used for statistical analyses in terms of basic patient information, wound type and dressing use, number of visits and expenses.ResultsA total of 10 880 cases were enrolled. The average age of the patients treated was (45.23±13.45) years old. Patients from the Central District, where the hospital was located in, accounted for the highest proportion (38.63%). The proportion of acute skin and soft tissue injuries was higher than that of chronic skin and soft tissue injuries (62.51% vs. 37.49%). According to the proportions from high to low, the top three chronic skin and soft tissue injuries were postoperative refractory wounds (19.63%), skin and soft tissue infections (3.90%), and stoma complications (3.04%), respectively. A total of 22 937 functional wound dressings were used, of which non-woven outer dressings accounted for 47.52%. Patients with acute skin and soft tissue injuries had a higher healing rate compared with those with chronic skin and soft tissue injuries (96.65% vs. 43.03%, P<0.05). The type of skin and soft tissue injuries with the most visits was cancerous wound [the median (lower quartile, upper quartile) was 68 (35, 121) visits], and the one with the least visits was acute skin and soft tissue injuries [the median (lower quartile, upper quartile) was 2 (1, 7) visits].ConclusionsAs the distance between residence and hospital grows, the number of patients decreases, suggesting that the specialized nursing assistance has achieved initial results in remote areas, but the task of assistance in surrounding areas is still heavy. The type of skin and soft tissue injuries is changing under the concept of enhanced recovery after surgery, and wound care plays an important role in the recovery of patients after surgery. The concept of wet healing and new dressings to promote wound healing are widely used, but still need to be further popularized among patients and medical staff. For chronic wounds that are more expensive to treat, it is necessary to formulate comprehensive treatment plans such as wound treatment, psychological support, and systemic nutrition to promote healing.

  • Therapeutic and safety evaluation of third-generation super-mini percutaneous nephrolithotomy in treating ≤ 2.5 cm kidney calculi with high CT value

    ObjectiveTo evaluate the efficacy and safety of the third-generation super-mini percutaneous nephrolithotomy (SMP) for the treatment of kidney calculi with diameter of ≤2.5 cm and CT value of ≥700 Hu, and discuss the feasibility of adopting the technology in primary hospitals.MethodsThe clinical data of 64 patients with unilateral kidney calculi (CT value ≥700 Hu, diameter ≤2.5 cm) treated in the People’s Hospital of Leshan Central District between July 2017 and July 2018 were retrospectively analyzed. After random assignment, 30 patients were treated with SMP and 34 were with mini percutaneous nephrolithotomy (MPCNL). The pre-, intra-, and post-operative data were compared and analyzed to evaluate the efficacy and safety.ResultsThe unilateral lesion operations of both groups were successfully completed in the first phase. All patients were given double J tubes after operation, and there were no major complications such as post-operative hemorrhage and sepsis. There was no statistically significant difference in the post-operative hemoglobin decrease, post-operative immediate stone removal rate, post-operative stone removal rate after one month, or the rate of procalcitonin >0.1 μg/L between the two groups (P>0.05). The differences in the lithotripsy time [(29.63±6.28) vs. (25.21±5.19) minutes], post-operative hospital stay [(5.33±0.61) vs. (9.44±0.96) days], rate of indwelling renal fistula (3.3% vs. 50.0%), analgesic demand rate (10.0% vs. 58.8%), and postoperative infectious fever rate (6.7% vs. 26.5%) between SMP group and MPCNL group were statistically significant (P<0.05).ConclusionsSMP has the advantages of less trauma, low systemic inflammatory response syndrome incidence, less pain, quick rehabilitation, short hospital stay, tubeless after surgery, etc. It is worthy of extensive promotion in primary hospitals.

  • Research progress of mitogen activation protein kinase signaling pathway in rheumatoid arthritis

    Rheumatoid arthritis (RA) is a chronic autoimmune disease remarkably characterized by synovitis of joints, whose pathogenesis is complicated and not yet fully elucidated. A variety of cells, cytokines and intercellular signaling pathways are involved in the occurrence and development of RA. The mitogen activation protein kinase (MAPK) signaling pathway is closely related to the pathogenesis of RA, and plays an important role in the formation of pannus, synovitis, and bone destruction. This paper reviews the research progress of MAPK signaling pathway in RA from the aspects of the interaction of MAPK signaling pathway with a variety of key cells and cytokines in the pathogenesis of RA, in order to provide a direction and theoretical basis for anti-RA drug therapy research.
