RESUMO
Radiation-induced injury, a body dysfunction caused by irradiation, is associated with the dose, duration, and speed of radiation and is predominantly derived from radiation therapy for patients with malignant tumors. The current clinical treatment mainly includes amelioration of injury, alleviation of symptoms, and improvements in function restoration of the affected sites because of lack of targeted agents specific to radiation-induced injuries. Research and development of preventive and therapeutic agents against radiation-induced injuries are of great significance to reduce the body damages caused by radiotherapy and improve the quality of life of cancer survivors. This review summarizes the radiation-induced injury and its mechanisms, radioprotectants, and therapeutic agents for radiation, and proposes future development directions, so as to provide a reference for alleviation of radiation-induced injury and improvement in prognosis.
RESUMO
Objective To explore the relationship between the outpatient visits for adult asthma and air pollution in a tertiary hospital in Hefei. Methods The number of outpatient visits for asthma in a tertiary hospital in Hefei from 2014 to 2020 was collected. The air pollutant data was obtained through the Hefei Air Monitoring Station, and the meteorological indicators of the same period were collected through the China Meteorological Network. The R statistical software was used to establish a generalized additive model to analyze the lag effect of air pollution on the number of outpatient visits for asthma. Results From 2014 to 2020, there were 7 220 asthma outpatients in the tertiary hospital in Hefei, including 3104 males and 4 116 females, 3 798 patients in warm season, and 3 422 patients in cold season. During the period, the average concentrations of SO2, NO2, CO, O3, PM10, and PM2.5 were 11.9μg/m3, 40.1μg/m3, 0.9 mg/m3, 87.3μg/m3, 81.3μg/m3, and 55.7μg/m3, respectively. The results of the single-pollutant model showed that every 10μg/m3 increase in SO2 concentration increased the risk of asthma by 0.74% (95%CI: 0.22%-1.29%), and the effect was the greatest on Lag2 day. NO2 increased the risk of asthma by 0.31% (95%CI: 0.13%-0.49%), with the greatest effect on Lag0 day. The analysis of the dual pollutant model found that whereas the effect of SO2 decreased after the incorporation of NO2, the effect increased after the incorporation of CO, O3, PM10, or PM2.5, respectively. The effect of NO2 on asthma decreased after the incorporation of SO2, whereas the effect on asthma increased after the inclusion of CO, PM10, or PM2.5. Stratified analysis of cold and warm seasons showed that the effect of NO2 on asthma was the greatest in lag0 in cold season. The effect of SO2 was higher in cold season than in warm season, and it was the highest in lag2. The gender stratification analysis showed that the effects of SO2 and NO2 on male asthma were higher than those on females. Conclusion From 2014 to 2020, the increase of SO2 and NO2 concentrations in Hefei is positively correlated with the risk of asthma in the outpatient department of a tertiary hospital. The effect has a certain lag. It is of great significance to formulate relevant preventive measures for the occurrence and attack of asthma.
RESUMO
@#Meibomian gland dysfunction(MGD)is a chronic, diffuse blepharoplasty that is characterized by obstruction of the terminal ducts of the blepharoplasty gland and abnormal lid ester secretion, which is a common ocular surface disease as well as the major cause of hyper evaporation type dry eye. MGD can cause ocular surface lid ester abnormalities and bacterial proliferation, which in turn leads to associated ocular symptoms. Physical therapies and medicines are widely used to treat MGD in clinics. Through the topical or systemic use of antibiotics that are effective anti-bacteria medicine, ocular surface symptoms caused by MGD-induced bacterial proliferation and abnormal eyelid lipids can be alleviated. Currently, the effectiveness of various types of antibiotics in treating MGD has been demonstrated. In this review, the mechanism, modality, and efficacy of various antibiotics in the treatment of MGD were highlighted and summarized from the perspective of topical or systemic use of antibiotics, which can provide promising guidance for clinical treatments of MGD.

RESUMO
Objective To explore the variation trend of natural killer (NK) cell subsets in the recipients infected with cytomegalovirus (CMV) after renal transplantation. Methods Clinical data of 92 renal transplant recipients were retrospectively analyzed. All recipients were divided into the CMV infection group (n=43), CMV infection recovery group (n=13), stable renal function group (n=15), rejection group (n=11) and other infection group (n=10). In addition, healthy adult volunteers were enrolled in the healthy control group (n=15). The proportion of NK cells in peripheral blood, the expression proportion and the mean fluorescence intensity (MFI) of CD226 and CD16 in NK cells were observed and statistically compared among different groups. Results The proportion of NK cells was 4.9% (2.2%, 11.5%) in the CMV infection group and 3.7% (2.3%, 6.5%) in the CMV infection recovery group, which were significantly lower than those in the other groups (all P < 0.05). The expression proportion of CD226 and CD16 in NK cells in the CMV infection group was significantly lower compared with those in the healthy control group and stable renal function group(all P < 0.05). The expression proportion of CD226 and CD16 in NK cells in the CMV infection recovery group was remarkably higher than those in the CMV infection group (both P < 0.05). The MFI of CD226 and CD16 in the CMV infection group was significantly lower than those in the healthy control group (both P < 0.05). The MFI of CD226 and CD16 in the CMV infection recovery group was significantly higher than those in the CMV infection group (both P < 0.05). Conclusions The expression proportion and MFI of CD226 and CD16 in NK cells are down-regulated in CMV infection period, whereas up-regulated during the CMV infection recovery period, prompting that CD226 and CD16 expressed by NK cells are intimately correlated with the course of CMV infection.

AIM: To evaluate the efficacy of implantable collamer lens (ICL)-V4c implantation in the correction for high myopia. METHODS: This retrospective analysis collected twenty-five patients (43 eyes) with high myopia treated with ICL/TICL implantation from September to December 2016 at Department of Ophthalmology, West China Hospital. Routine ophthalmic examinations were performed. The patients were followed 3mo to monitor uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refractive error, intraocular pressure, corneal endothelial cell count, contrast sensitivity and scores for Quality of Life lmpact of Refractive Correction Questionnaire ( QIRC ). Statistical analyses were performed using repeated measures ANOVA, LSD-t test and paired-samples T test. RESULTS: Postoperative UCVA and BCVA were significantly higher than before surgery (all P<0. 01). Postoperative spherical mirrors at all time points were lower than before surgery(all P<0.01),and there was no significant difference between the different time point postoperative (all P>0. 05). The safety index in 3mo postoperatively was 1.38士0.24 and the effective index was 1. 22士0. 15. There was no statistical difference in intraocular pressure between preoperative and postoperative time points (F=1.464, P=0.215). There was no statistical difference in endothelial cell density at 3mo after surgery compared to preoperative (t=-0.544, P= 0. 586). The postoperative Log contrast sensitivity (LogCS) of 12.0 cycles per degree (c/d) and 18.0 c/d were significantly higher compared to the preoperative (F=4.347, P=0.010; F=4.539, P=0.005; respectively), but other (the postoperative LogCS of 3.0 c/d and 6.0 c/d) differences were statistically insignificant (F=1.094, P=0.354;F=1 325,P=0.271;respectively). There was no significant difference in the amount of change in the QIRC scores between preoperative and postoperative(F=2.669, P=0 094). CONCLUSION: ICL V4c implantation is a safe and effective method for the correction of high myopia.

RESUMO
Background and purpose:Radical nephroureterectomy can be performed in a variety of ways, and each method has its advantages and disadvantages. It still remains controversial for choosing the surgical methods. In this study, we chose six surgical methods and investigated the safety and efficacy of different methods in treating upper urinary tract carcinoma.Methods:We retrospectively analyzed 135 patients with upper urinary tract transitional cell carcinoma who underwent operations in our hospital from Jan. 2002 to Oct. 2013, and compared the data of six different operations in-cluding operating time, volume of bleeding, time of bowel function recovery and incidence of bladder carcinomas.Results:The operations were successfully completed in groups A and B. Five cases in group C were transferred into group A be-cause of failing to pull the nub of the ureter. Two cases in group D were transferred into group A because of failing to pull the nub of the ureter. Three cases in group E were transferred into group D and 1 case was transferred into group A because of adhesion or bleeding. One case in group F was transferred into group A because of bleeding. There was no statistically significant difference in survival rates among six operations.Conclusion:Six operations are all safe and effective for the treatment of upper urinary tract carcinomas. Each method has its advantages and disadvantages. We should choose differ-ent methods according to particular cases.

RESUMO
Objective To summarize the treatment experience of extensive burn merging smoke inhalation acute lung injury(SIALI)in 32 early stage cases,and to provide a reference for the further improvement of success rate in early stage. Methods A total of 32 cases of extensive burn merging SIALI resulting from mine explosion that received clinical treatment and triage from November to December in 2014 were enrolled for the study. In addition,the experience of triage and prognosis(after injured in a month)to guide therapy was analyzed. Results Two of the 32 patients died from respiratory failure in shock period,after shock period(3 days after injured),19 bad sufferers were cured in the local hospital,and the oth?er 11 cases in stable condition were triaged to the nearby hospital. 1 month follow?up results showed that:patients who received therapy in local hospi?tal,one died from MODS in 3 weeks,one died from kidney failure in 4 weeks. The other 28 patients were alive. Conclusion For these patients who suffering from extensive burn merging SIALI received therapy in early stage,we should not only schedule positive anti?shock,tracheotomy,antibiot?ics,escharectomy and nutritional support or other treatments,but also face to the challenge of lacking medical resources from too more patients. Thus,we suggest to triage the wounded to nearby hospital after anti?shock treatment,so as to improve the success rate in early stage.
RESUMO
Most of the transfusion adult outpatients are old people with chronic disease, and theirsmall blood vessels become less elastic with age. They need long course and repeated localised puncture site. On the base of that fact, the author describes the 5.5gauge scalp acupuncture and 7 gauge scalp acupuncture about their use on the patients. The 5.5 gauge scalp acupuncture is smaller and shorter, so it has the advantage of high success ratio and it is easier to be fixed. Additionally, the transfusion speed is easy to be controlled, which reduces the ratios of transfusion reaction and adverse drug reactions. The pinhole is small and can be healed faster. The congestion around the puncture location is less than that of the 7 scalp acupuncture. It can alleviate the pain for patients and increase satisfaction. To sum up, the 5.5 gauge scalp acupuncture should be used widely as we allocate“people oriented”and“All for the patients”.
RESUMO
By a orthogonal experiment, the influence of different ratio of phosphorus and potassium fertilizers on imperatorin, isoimperatorin and psoralen contents and yield of Glehnia littoralis were studied. The results showed that root dry weight and the yield of G. littoralis increased when reasonably applied phosphorus fertilizer combined with potassium fertilizer within a certain range. And the influence of phosphorus fertilizer was greater than that of potassium fertilizer. The optimal value of root dry weight and yield achieved at both P2O5 360 kg x hm(-2), K2O 270 kg x hm(-2) and P2O5 360 kg x hm(-2), K2O 180 kg x hm(-2). The effects of different phosphorus and potassium treatments on the content of imperatorin, isoimperatorin and psoralen in G. littoralis were determined, which shows that the content increased with the moderate increase of phosphorus and potassium. And the effects of phosphorus fertilizer were more significantly. The isoimperatorin content achieved the largest value at P2O5 360 kg x hm(-2), K2O 270 kg x hm(-2), also a larger content of imperatorin and psoralen. The imperatorin content is the largest when applied P2O5 360 kg x hm(-2), K2O 180 kg x hm(-2), and the isoimperatorin content was higher as well. So that the treatment of P2O5 360 kg x hm(-2), K2O 180 kg x hm(-2) are suitable for promote to the agricultural production, which could improve the quality and yield of G. littoralis.

Purpose To study the clinicopathologic features, immunophenotype and differential diagnosis of solid papillary carcinoma (SPC) of breast.Methods 73 cases of breast SPC with or without invasive carcinoma were collected, and the clinical data and histopathologic features were analyzed with further investigation of transmission electron microscopy and immunohistochemical staining (EnVision method). Selected antibodies included cytokeratin (CK), myoepithelial markers, neuroendocrine markers, proliferation marker Ki-67 and ER,PR,c-erbB-2,etc.Results All the patients were females with mean age of 64.7 years.The presenting symptoms were either a palpable breast mass or nipple discharge.Metastasis was observed in 43 cases who had undergone axillary lymph node dissection. Histologically, the tumor displayed a solid-papillary growth pattern, with mucin production demonstrated in 25 cases. Intraductal papilloma was not uncommon at the peripheral area of the tumor. The tumor cells were polygonal, oval, spindled or signet ring-like and contained abundant eosinophilic to granular cytoplasm and mildly to moderately pleomorphic nuclei. More than 5 mitotic figures/10 HPF were observed in 51 cases. 43 cases contained foci of invasive carcinoma which showed similar cytologic features as those of in-situ component. Immunohistochemical study showed that the tumor cells were negative for basal cell cytokeratin; positivity for smooth muscle actin-alpha and p63 were demonstrated in the myoepithelial layers of fibrovascular cores, as well as around the expanded ductolobular units.Most cases also showed cytoplasmic positivity for chromogranin A (89.0%), synaptophysin (86.3%) and neuron-specific enolase (95.9%).The proliferatiing index, as highlighted by Ki-67 imnunostaining, was 9.2%.The tumor mainly expressed estrogen receptor and progesterone receptor. The staining for c-erbB-2 oncoprotein was negative in the most cases. Neuroendocrine granules were seen under transmission electron microscope in the cytoplasm.Conclusions SPC represents a subgroup of low-grade ductal carcinoma in situ.SPC predilection in older women is associated with mucinous and neuroendocrine components. Follow-up data suggest that SPC has a good prognosis.
