ABSTRACT

Objective:To investigate the effect of total gastric replacement of esophagus and tubular gastric replacement of esophagus on gastroesophageal reflux after esophageal cancer surgery, and the correlation between the anastomosis position and width of tubular stomach and gastroesophageal reflux.Methods:Eighty-eight patients with esophageal cancer admitted to Lu′an Hospital of Peking University Medical Group were retrospectively analyzed. According to the operation methods, they were divided into study group (tube stomach instead of esophagus anastomosis) and control group (whole stomach instead of esophagus anastomosis). The effects of two operation methods on gastroesophageal reflux were compared, and the effects of the position and width of tube stomach instead of esophagus anastomosis on the symptoms were analyzed.Results:Three months after operation, the frequency of acid reflux ≥ 5 minand 24 h acid reflux in the study group were less than those in the control group: (2.5 ± 1.7) times vs. (6.2 ± 2.1) times, (17.3 ± 8.8) times vs. (31.5 ± 7.9) times; the total time of pH < 4 and the longest acid reflux time in the study group were shorter than those in the control group: (85.3 ± 30.1) min vs. (118.2 ± 32.6) min, (22.4 ± 6.8) min vs. (31.8 ± 7.4) min; and the differences were statistically significant ( P<0.05). The reflux disease questionnaire score and the incidence of gastroesophageal reflux disease in the study group were lower than those in the control group: (8.9 ± 4.6) scores vs. (13.8 ± 4.1) scores, 6.7%(3/45) vs. 23.3%(10/43), and the differences were statistically significant ( P<0.05). In the 4 subgroup of the study group, the incidence of reflux symptoms, pH<4 cumulative time and the number of reflux symptoms were the lowest in the cervical anastomosis+width<3 cm subgroup, and the histological inflammatory reaction grade of esophageal mucosa under endoscopy was the lightest in the study group, and the differences were statistically significant ( P<0.05). Conclusions:Compared with total gastric anastomosis, tube stomach instead of esophagus anastomosis can reduce the incidence of gastroesophageal reflux more effectively, and neck anastomosis+tube stomach width <3 cm and anastomosis method are the best for gastroesophageal reflux.

ABSTRACT

ObjectiveTo investigate the efficacy and safety of CalliSpheres microsphere-transcatheter arterial chemoembolization (CSM-TACE) versus conventional transcatheter arterial chemoembolization (cTACE) in the treatment of hepatocellular carcinoma (HCC) through a meta-analysis. MethodsPubMed, Web of Science, Cochrane Library, CNKI, Wanfang Data, and VIP were searched for all Chinese and English articles on the application of CSM-TACE and cTACE in HCC published up to the end of October, 2020. After quality assessment was performed for the articles included, RevMan 5.3 software provided by Cochrane Library was used for analysis. ResultsA total of 15 studies were included, with 1535 patients in total. This meta-analysis showed that compared with the patients receiving cTACE, the patients receiving CSM-TACE had significantly higher 1-year overall survival rate (odds ratio [OR]=2.26, 95% confidence interval [CI]: 1.63-3.13, P<0.000 01), 2-year overall survival rate (OR=1.73, 95%CI: 1.20-2.50, P=0.003), and 2-year progression-free survival rate (OR=1.60, 95%CI: 1.05-2.43, P=0.03). In terms of safety, compared with the patients receiving cTACE, the patients receiving CSM-TACE had significantly lower incidence rates of postoperative vomiting (OR=0.65, 95%CI: 0.46-0.92, P=0.01), bone marrow suppression (OR=0.17, 95%CI: 0.05-0.54, P=0.003), and neutropenia (OR=0.18, 95%CI: 0.07-045, P=0.000 3), while there were no significant differences between the two groups of patients in postoperative pyrexia, abdominal pain, and ascites (all P>0.05). ConclusionCSM-TACE has significant advantages in improving 1- and 2-year overall survival rates and 2-year progression-free survival rates and can significantly reduce the incidence rates of postoperative vomiting, bone marrow suppression, and neutropenia. Therefore, CSM-TACE is a safe and effective treatment method.

ABSTRACT

BACKGROUND@#Taxanes are an essential class of antineoplastic agents used to treat various cancers and are a fundamental cause of hypersensitivity reactions. In addition, other adverse events, such as bone marrow toxicity and peripheral neuropathy, can lead to chemotherapy discontinuation. This study aimed to evaluate the safety of taxanes in the real world.@*METHODS@#Taxane-associated adverse events were identified by the Medical Dictionary for Regulatory Activities Preferred Terms and analyzed and compared by mining the US Food and Drug Administration Adverse Event Reporting System pharmacovigilance database from January 2004 to December 2019. Reported adverse events, such as hypersensitivity reaction, bone marrow toxicity, and peripheral neuropathy, were analyzed with the following signal detection algorithms: reporting odds ratio (ROR), proportional reporting ratio (PRR), multi-item gamma Poisson shrinker (MGPS), Bayesian confidence propagation neural network (BCPNN), and logistic regression methods. Adverse outcome events and death outcome rates were compared between different taxane groups using Pearson's χ2 test, whereas significance was determined at P < 0.05 with a 95% confidence interval (CI).@*RESULTS@#A total of 966 reports of hypersensitivity reactions, 1109 reports of bone marrow toxicity, and 1374 reports of peripheral neuropathy were analyzed. Compared with paclitaxel and docetaxel, bone marrow toxicity following the use of nab-paclitaxel had the highest ROR of 6.45 (95% two-sided CI, 6.05-6.88), PRR of 5.66, (χ2 = 4342.98), information component of 2.50 (95% one-sided CI = 2.34), and empirical Bayes geometric mean of 5.64 (95% one-sided CI = 5.34). Peripheral neuropathy following the use of nab-paclitaxel showed a higher ROR of 12.78 (95% two-sided CI, 11.55-14.14), PRR of 12.16 (χ2 = 4060.88), information component of 3.59 (95% one-sided CI = 3.25), and empirical Bayes geometric mean of 12.07 (95% one-sided CI = 11.09).@*CONCLUSIONS@#The results showed that bone marrow toxicity and peripheral neuropathy were the major adverse events induced by taxanes. Nab-paclitaxel exhibited the highest potential for taxane-associated adverse events. Further research in the future is warranted to explain taxane-associated adverse effects in real-world circumstances.

ABSTRACT

BACKGROUND@#Compared to adult studies, studies which involve the treatment of pediatric congenital hypogonadotropic hypogonadism (CHH) are limited and no universal treatment regimen is available. The aim of this study was to evaluate the feasibility of human chorionic gonadotropin (hCG)/human menopausal gonadotropin (hMG) therapy for treating male adolescents with CHH.@*METHODS@#Male adolescent CHH patients were treated with hCG/hMG (n = 20) or a gonadotropin-releasing hormone (GnRH) pump (n = 21). The treatment was divided into a study phase (0-3 months) and a follow-up phase (3-12 months). The testicular volume (TV), penile length (PL), penis diameter (PD), and sex hormone levels were compared between the two groups. The TV and other indicators between the groups were analyzed using a t-test (equal variance) or a rank sum test (unequal variance).@*RESULTS@#Before treatment, there was no statistical difference between the two groups in terms of the biochemistry, hormones, and other demographic indicators. After 3 months of treatment, the TV of the hCG/hMG and GnRH groups increased to 5.1 ± 2.3 mL and 4.1 ± 1.8 mL, respectively; however, the difference was not statistically significant (P > 0.05, t = 1.394). The PL reached 6.9 ± 1.8 cm and 5.1 ± 1.6 cm (P  0.05, t = 0.314). After 9 to 12 months of treatment, the T level was higher in the hCG/hMG group. Other parameters did not exhibit a statistical difference.@*CONCLUSIONS@#The hCG/hMG regimen is feasible and effective for treating male adolescents with CHH. The initial 3 months of treatment may be a window to optimally observe the strongest effects of therapy. Furthermore, results from the extended time-period showed positive outcomes at the 1-year mark; however, the long-term effectiveness, strengths, and weaknesses of the hCG/hMG regimen require further research.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT02880280; https://clinicaltrials.gov/ct2/show/NCT02880280.

ABSTRACT

Heterotopic pregnancies are rare and difficult to be diagnosed early. A patient with combined intrauterine pregnancy and cervical pregnancy was admitted in Qingdao Municipal Hospital in 2019. The patient complained of abnormal vaginal bleeding after menopause and was misdiagnosed as simple intrauterine pregnancy. She underwent artificial abortion and suffered intraoperative hemorrhage. To stop bleeding, she received the treatment of uterine artery embolization immediately. Afterwards, cervical residual pregnancy tissues started necrosis, blood β-human chorionic gonadotropin level and the cervix appearance gradually returned to normal. This report suggests that cervical heterotopic pregnancy inclines to be mis diagnosed. Correct diagnosis should be made as soon as possible. Selective uterine artery embolization is an effective measure to prevent and treat massive bleeding.

ABSTRACT

OBJECTIVE@#To observe the effect of early intervention of bone-nearby acupuncture (BNA) combined with electroacupuncture (EA) on the expression of histone deacetylase1(HDAC1), histone deacetylase 2 (HDAC2) andμ-opioid recepter (MOR) in dorsal root ganglia (DRG) of bone cancer pain-morphine tolerance (BCP-MT) rats, and to explore its possible mechanism.@*METHODS@#A total of 35 SD rats were randomized into a sham BCP group (=6), a BCP group (=7), a MT group (=7), a BNA+EA group (=8) and a shame BNA group (=7). Except of the sham BCP group, cancer cell inoculation operation at left tibia was given in the other 4 groups to establish the bone cancer pain model. In the MT group, the BNA+EA group and the shame BNA group, intraperitoneal injection of morphine hydrochloride was given to establish the morphine tolerance model. After the operation, bone-nearby acupuncture combined with electroacupuncture was applied at "Zusanli" (ST 36) and "Kunlun" (BL 60) in the BNA+EA group, with dilatational wave, 2 Hz/100 Hz in frequency, 0.5 to 1.5 mA in intensity. Intervention in the shame BNA group was applied at the same time and acupoints as those in the BNA+EA group, the needles were pierced the skin without any electrical stimulation. The needles were retained for 30 min, once a day for continuous 7 days in both BNA+EA and shame BNA groups. Before and 10, 11, 15, 22 days after the operation, the left paw withdrawal threshold (PWT) was measured in the 5 groups. The levels of HDAC1, HDAC2 and MOR in DRG were detected by Western blot.@*RESULTS@#Ten days after the cancer cell inoculation operation, the PWT of the BCP, MT, BNA+EA and sham BNA groups was decreased compared with the sham BCP group (0.05); the PWT of the BNA+EA group was increased compared with the MT and sham BNA group (<0.01). In the BCP group, the DRG levels of HDAC1 and HDCA2 were increased, while the level of MOR was decreased compared with the sham BCP group (<0.05, <0.01). In the MT group, the DRG level of HDAC1 was increased compared with the BCP group (<0.05). In the BNA+EA group, the DRG level of HDAC1 was decreased compared with the MT group and the sham BNA group (<0.01, <0.05), while the level of MOR was increased (<0.01).@*CONCLUSION@#Early intervention of bone-nearby acupuncture combined with electroacupuncture can relieve the morphine tolerance in bone cancer pain rats, it may relate to down-regulating the expression of HDAC1 and up-regulating the expression of MOR in the dorsal root ganglia.

ABSTRACT

Objective:To investigate the application of low-dose chest CT(LDCT) in the screening of pulmonary subsolid nodules in population and the application value of artificial intelligence.Methods:People who received chest LDCT screening between January 2015 and December 2017 were included. A retrospective study was developed to analyze the enrolled population features , detection of pulmonary subsolid nodules and independent predictors of subsolid nodules , and to evaluate the accuracy of the artificial intelligence reading method.Results:Result of three cross-sectional studies reveals that the detection rates of pulmonary subsolid nodules were 0.42%, 0.69% and 0.92% in three rounds. 726 cases who completed the three rounds of screening were included in the cohort study. The cohort population was predominantly male(83.2%), with a median age of 43 years, and nearly half of the subjects(47.0%) had a history of smoking. GEE revealed that the patient's family history of lung cancer( OR=8.753, 95% CI: 1.877-40.816, P=0.006) was an independent predictor of the detection of subsolid nodules. In the 110 kVp tube voltage group, AUC of AI model was 0.740, and AUC of the manual reading method was 0.721, no significant differences were observed( P=0.502); when the preseted cutoff value of AI model was 0.75, the NRI was -0.15, indicating the accuracy of AI model was inferior to manual method( P=0.006). In the 130 kVp tube voltage group, AUC of the model was 0.888, and AUC of the manual reading method was 0.756, no significant differences were observed( P=0.128); and the NRI was 0.19, indicating the accuracy of AI model was not inferior to manual method( P=0.123). Conclusion:This population' s detection rates of pulmonary subsolid nodules were 0.42%-0.92%. Family history of lung cancer was an independent predictor of subsolid pulmonary nodules. The result of AI pulmonary nodule detection model could be a reference when the training set data parameters match the actual application parameters.

ABSTRACT

OBJECTIVE@#To observe the expression of GABA receptor mRNA in different brain regions of the central nervous system in chronic inflammatory pain rats and the intervention effect of electroacupuncture (EA).@*METHODS@#A total of 48 SPF male SD rats were randomly divided into a blank control group, a model control group, an EA group and a sham EA group, 12 rats in each group. The model of chronic inflammatory pain was established by injecting Freund's complete adjuvant into the foot. The EA group was treated with EA 28 days after the model establishment. The "Housanli" (ST 36) and "Kunlun" (BL 60) were selected and treated with dilatational wave, 2 Hz/100 Hz in frequency, 0.5-1.5 mA for 30 min; EA was given only once. In the sham EA group, the same acupoints were selected but the needles were only inserted into subcutaneous area; EA was connected for 30 min without electrical stimulation. The behavior changes of mechanical pain threshold and thermal pain threshold before model establishment, 1 day, 3 days, 7 days, 14 days, 21 days and 28 days after the model establishment as well as emotional behavior 29 days after the model establishment were observed; the relative expressions of GABA receptor mRNA in anterior cingulate cortex, amygdala and hypothalamus were observed.@*RESULTS@#Compared with the blank control group, the change rates of mechanical pain threshold and thermal pain threshold in the model control group were decreased significantly 1 day, 3 days, 7 days, 14 days, 21 days, 28 days after model establishment (0.05). Compared with the blank control group, the expression of GABA receptor mRNA in the amygdala was decreased significantly in the model control group (<0.01); compared with the model control group and the sham EA group, the expression of GABA receptor mRNA in amygdala was increased after intervention in the EA group (<0.01).@*CONCLUSION@#Single treatment of EA could significantly increase the mechanical pain threshold and thermal pain threshold, improve abnormal emotional behavior in rats with chronic inflammatory pain, which may be related to the increasing of expression of GABA receptor mRNA in the amygdala.

ABSTRACT

Objective To evaluate the nutritional value of yeast protein, and to provide laboratory evidence for its application in the field of food and health food. Methods The amino acids content of yeast protein, soybean protein, whey protein and mixed protein was detected. Five nutritional evaluation methods, including amino acid score, ratio of total essential amino acid, ratio coefficient of amino acid, Pearson's correlation coefficient, and equally weighted gray correlation analysis were used to evaluate the protein quality. The protein efficacy test of the four proteins was performed in Sprague-Dawley rats to compare their nutritional value in vivo. Results The results showed that yeast protein was rich in essential amino acids, accounting for 47.58% of the total amino acids, and the ratio of essential amino acids to non-essential amino acids reached 0.91. Five nutritional evaluation methods all revealed that the yeast protein was an excellent protein in quality. The results of the protein efficacy test showed that yeast protein was able to promote the growth and development of the animals, and keep them in good nutritional condition, which was similar to whey protein, soy protein, and casein. The mixed protein had the highest corrected efficiency ratio among all the proteins tested in this study, possibly because the mixed ingredients made the amino acids complementary and thus had higher nutritional value. Conclusion Yeast protein can be used as a useful supplement to plant-derived and animal-derived protein products.

ABSTRACT

Objective::To investigate the clinical efficacy and mechanism of Guige Lingxian decoction combined with moxibustion at neck Jiaji acupoint on cervical spondylotic radiculopathy (CSR) of wind-cold-dampness arthralgia syndrome. Method::Totally 120 cases of cervical spondylotic radiculopathy with wind-cold-dampness syndrome were randomly divided into two groups: traditional Chinese medicine(TCM) group and combination group, with 60 cases in each group. The TCM group was treated with Guige Lingxian Tang 150 mL/time, twice a day. The combination group was treated with moxibustion at neck Jiaji acupoint in addition to the therapy of the TCM group, 30 minutes/time, once a day. Both groups were treated for 8 weeks. CSR 20 subscale score, SF-36 scale score, typical symptoms and signs remission time were recorded. The total effective rate and the cure rate were recorded after treatment. Serum levels of leukotriene B4(LTB4), leukotriene C4(LTC4), leukotriene D4 (LTD4), chitinase protein 40 (YKL-40), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were measured by enzyme linked immunosorbent assay(ELISA) before and after treatment. Result::The total effective rate was 98.11%(52/53), and the cure rate was 43.39%(23/53) in the combination group, which were higher than 91.04%(61/67) and 20.89%(14/67) in the TCM group (P<0.05). Compared with the TCM group, the scores of CSR 20 subscale and SF-36 scale in combination group were increased (P<0.05), and the remission time of typical symptoms and signs was shortened. Serum levels of LTB4, LTC4, LTD4, YKL-40, IL-1β and TNF-α were decreased (P<0.05). Conclusion::Moxibustion at neck Jiaji acupoint combined with Guige Lingxian decoction is effective in treating CSR of wind-cold-dampness arthralgia syndrome, which is worthy of clinical promotion. Its mechanism may be related to the inhibition of the expression of LT, and the reduction of the content of IL-1β and TNF-α in serum, thus promoting the repair of cervical cartilage and increasing the pain threshold.

ABSTRACT

Objective To evaluate the relationship betweenα2 adrenergic receptors and expression of Nav1. 8 in dorsal root ganglion (DRG) neurons, and to illuminate the mechanism of dexmedetomidine-induced reduction of acute visceral pain in rats. Methods Thirty-two clean-grade healthy adult male Spra-gue-Dawley rats, aged 6-8 weeks, weighing 180-220 g, were divided into 4 groups ( n=8 each) using a random number table method: control group ( group C ) , acute visceral pain group ( group VP ) , dexmedetomidine group (group D), and dexmedetomidine plus atipamezole group (group DA). In VP, D and DA groups, 10-3 mmol∕L capsaicin 1. 3 ml was injected into the rectum at a dose of 10-3 mmol∕L to establish the acute visceral pain model, while the equal volume of normal saline was given instead in group C. Atipamezole 1 mg∕kg was subcutaneously injected through the back of the neck at 20 min before establishing the model in group DA. Dexmedetomidine 10μg∕kg was injected through the tail vein at 15 min before establishing the model in D and DA groups, while the equal volume of normal saline was given instead at the correspording time points in C and VP groups. The visceral pain behavior score was recorded at 1 h after establishing the model. The animals were then sacrificed, and DRGs of the lumbar segment (L3-6) were removed for determination of the number of Nav1. 8 positive DRG neurons (by immunohisto-chemistry) and expression of Nav1. 8 mRNA (by quantitative real-time polymerase chain reaction). Results Compared with group C, the visceral behavior scores and the number of Nav 1. 8 positive DRG neurons were significantly increased, and the expression of Nav 1. 8 mRNA was up-regulated in VP, D and DA groups (P<0. 05). Compared with group VP, the visceral behavior score and the number of Nav1. 8 positive DRG neurons were significantly decreased, and the expression of Nav 1. 8 mRNA was down-regulated in D and DA groups (P<0. 05). Compared with group D, the visceral behavior scores and the number of Nav1. 8 positive DRG neurons were significantly increased, and the expression of Nav1. 8 mRNA was up-regulated in group DA ( P<0. 05) . Conclusion The mechanism by which dexmedetomidine reduces acute visceral pain is related to activatingα2 adrenergic receptors and to down-regulating the expression of Nav1. 8 in DRG neu-rons of rats.

ABSTRACT

Objective@#To understand the consistency of ALK Ventana-D5F3 immunohistochemistry (IHC) interpretation in Chinese lung adenocarcinoma among histopathologists from different hospitals, and to recommend solution for the problems found during the interpretation of ALK IHC in real world, with the aim of the precise selection of patients who can benefit from ALK targeted therapy.@*Methods@#This was a multicenter and retrospective study. A total of 109 lung adenocarcinoma cases with ALK Ventana-D5F3 IHC staining were collected from 31 lung cancer centers in RATICAL research group from January to June in 2018. All cases were scanned into digital imaging with Ventana iSCANcoreo Digital Slide Scanning System and scored by 31 histopathologists from different centers according to ALK binary (positive or negative) interpretation based on its manufacturer′s protocol. The cases with high inconsistency rate were further analyzed using FISH/RT-PCR/NGS.@*Results@#There were 49 ALK positive cases and 60 ALK negative cases, confirmed by re-evaluation by the specialist panel. Two cases (No. 2302 and No.2701) scored as positive by local hospitals were rescored as negative, and were confirmed to be negative by RT-PCR/FISH/NGS. The false interpretation rate of these two cases was 58.1% (18/31) and 48.4% (15/31), respectively. Six out of 31 (19.4%) pathologists got 100% accuracy. The minimum consistency between every two pathologists was 75.8%.At least one pathologist gave negative judgement (false negative) or positive judgement (false positive) in the 49 positive or 60 negative cases, accounted for 26.5% (13/49), 41.7% (25/60), respectively, with at least one uncertainty interpretation accounted for 31.2% (34/109).@*Conclusion@#There are certain heterogeneities and misclassifications in the real world interpretation of ALK-D5F3 IHC test, which need to be guided by the oncoming expert consensus based on the real world data.

ABSTRACT

Objective To investigate the changes of serum corticosterone and inflammatory factors in rats with different burn degrees. Methods One hundred and fifty male healthy Wistar rats were randomly divided into normal control group, moderate and severe burn hormone treatment groups, and moderate and severe burn physiological saline treatment groups, each group with 30 rats. After anesthesia, the rat models with burn Ⅱ,Ⅲ degrees of 30% back surface area were replicated; the burn, fluid infusion and steroid therapy were not carried out in the normal control group. After modeling, the moderate and severe burn hormone treatment groups were given intra-abdominal cavity injection of hydrocortisone 200 mg/d; while in the moderate and severe burn normal saline treatment groups, normal saline 4 mL·kg-1·d-1 was injected into the abdominal cavity. The dynamic changes of serum corticosterone, tumor necrosis factor-α(TNF-α), and interleukin-6 (IL-6) levels were detected at 1, 4, 12 hours and 1, 3 and 7 days after burn injury in each group. Results The levels of serum corticosterone at different time points after moderate and severe burn injury treatment were higher than those in normal control group, the degree of increase at 4 hours after injury in severe burn saline treatment group was more significant than that in moderate and severe burn hormone treatment groups and moderate burn saline treatment group (ng/L: 200.45±2.63 vs. 110.56±9.23, 146.02±3.28, 160.02±8.22). Except the level at 1 hour after injury in the moderate and severe burn hormone treatment groups, the TNF-αlevels in all the other groups at different time points were significantly higher than those in the normal control group (all P < 0.05); the IL-6 levels in various treatment groups were all higher than the IL-6 level in the normal control group, moreover, the increase degree on 1 day after injury in the severe burn saline treatment group was more obvious than the degrees in the moderate and severe burn hormone treatment groups and the moderate burn saline treatment group [TNF-α(ng/L): 39.78±4.30 vs. 15.99±1.40, 20.58±2.10, 25.98±1.60, IL-6(ng/L): 210.20±6.70 vs. 125.45±3.10, 149.81±4.20, 161.40±3.80, all P < 0.05]. Conclusion The burn stress may lead to the significant increase of serum corticosterone level in rats, and the stress dose of hydrocortisone has a certain regulatory effect on serum corticosterone and inflammatory factors in rats after different degrees of burn.

ABSTRACT

Objective@#To investigate the influence of subchronic exposure to low-dose subchronic nano-nickel oxide (NNO) on the reproductive function of male rats and embryonic development of the pregnant rats.@*METHODS@#Fifty normal healthy male SD rats weighing 180-220 g were randomly divided into five groups of equal number, negative control, 4 mg/ml micro-nickel oxide (MNO), and 0.16, 0.8 and 4 mg/ml NNO, those of the latter four groups exposed to MNO or NNO by non-contact intratracheal instillation once every 3 days for 60 days, and then all mated with normal adult female rats in the ratio of 1∶2. After the female animals were confirmed to be pregnant, the males were sacrificed and the weights of the body, testis and epididymis obtained, followed by calculation of the visceral coefficients, determination of epididymal sperm concentration and viability and the nickel contents in the blood and semen by atomic fluorescence spectrometry. The female rats were killed on the 20th day of gestation for counting of the implanted fertilized eggs and live, dead and resorbed fetuses.@*RESULTS@#After 60 days of exposure, the rats of the NNO groups showed no statistically significant differences from those of the negative control and MNO groups in the weights of the body, testis and epididymis or visceral coefficients. Compared with the negative control group, the animals of the 0.8 and 4 mg/ml NNO groups exhibited markedly decreased sperm concentration ([9.36 ± 0.98] vs [7.49 ± 1.46] and [6.30 ± 1.36] ×10⁶/ml, P < 0.05) and viable sperm ([85.35 ± 9.16]% vs [68.26 ± 16.63]% and [65.88 ± 14.68] %, P < 0.05), increased morphologically abnormal sperm ([8.30 ± 2.47]% vs [13.99 ± 4.87]% and [15.38 ± 8.86] %, P < 0.05), and elevated rate of dead and resorbed fetuses (1.18% vs 6.89% and 7.37%, P < 0.05), blood nickel content ([0.13 ± 0.16] vs [0.52 ± 0.34] and [0.82 ± 0.44] mg/L, P < 0.05) and semen nickel content ([0.08 ± 0.13] vs [0.35 ± 0.23] and [0.63 ± 0.61] mg/L, P < 0.05). The nickel level in the semen was correlated significantly with that in the blood (r = 0.912, P <0.01), negatively with the rate of viable sperm (r = -0.879, P <0.01) and positively with the percentage of morphologically abnormal sperm (r = -0.898, P <0.01).@*CONCLUSIONS@#Sixty-day exposure to nano-nickel oxide at 0.8 and 4 mg/ml can produce reproductive toxicity in male rats and result in fetal abnormality in the females, while that at 0.16 mg/ml has no significant toxic effect on the reproductive function of the males.

ABSTRACT

Objective To investigate the effect of dexmedetomidine pretreatment on inflammatory visceral pain in rats. Methods Forty healthy male Wistar rats, weighing 200-300 g, aged 6-8 weeks, were divided into 5 groups ( n=8 each) using a random number table method: control group ( group C) , visceral pain group ( group VP ) , dexmedetomidine 1 μg∕kg group ( group Dex1 ) , dexmedetomidine 5μg∕kg group ( group Dex2) and dexmedetomidine 10μg∕kg group ( group Dex3) . The model of inflammato-ry visceral pain was established by intraperitoneally injecting 0. 9% acetic acid 10 ml∕kg in VP, Dex1, Dex2 and Dex3 groups, and the equal volume of normal saline was given instead in group C. At 15 min be-fore intraperitoneal injection, dexmedetomidine 1, 5 and 10μg∕kg were injected via the tail vein in Dex1, Dex2 and Dex3 groups, respectively, and the equal volume of normal saline was given instead in C and VP groups. Behavioral changes of rats were observed within 60 min after the model was established, and viscer-al pain index ( VPI) was calculated. Blood samples were collected from the hearts at 180 min after establis-hing the model for determination of tumor necrosis factor-alpha ( TNF-α) concentrations in serum. The ani-mals were then sacrificed, and colons were obtained for examination of pathological changes with a light mi-croscope. Results Compared with group C, the VPI and serum TNF-α concentrations were significantly increased in VP and Dex1-2 groups, and the serum TNF-αconcentrations were significantly increased ( P<0. 05), and no significant change was found in VPI in group Dex3 (P>0. 05). Compared with group VP, the VPI and serum TNF-α concentrations were significantly decreased (P<0. 05), and the pathological changes of colon tissues were significantly attenuated in group Dex1-3. Compared with group Dex1, the VPI and serum TNF-α concentrations were significantly decreased ( P<0. 01) , and the pathological changes of colon tissues were significantly attenuated in Dex2-3 groups. Compared with group Dex2, the VPI and ser-um TNF-α concentrations were significantly decreased (P<0. 01), and the pathological changes of colon tissues were significantly attenuated in group Dex3. Conclusion Dexmedetomidine pretreatment can miti-gate inflammatory visceral pain in rats.

ABSTRACT

Objective To analyze the image features and prognosis of primary central airway salivary gland-type tumor (SGT).Methods The clinical and imaging data of 25 cases with SGT confirmed by histopathology were retrospectively analyzed in our hospital from October 2009 to November 2017.Follow up of patients for survival was performed.Among 25 cases of SGT,there were 14 cases of adenoid cystic carcinoma (ACC),ten cases of mucoepidermoid carcinoma (MEC) and one case of mucoepidermoid carcinoma (EMC).All cases had non-enhanced CT scans (among which 20 cases underwent CT scan with contrast).Post-processing were performed to evaluate the location,range,density,degree of enhancement of the lesions and involvement of hilar or mediastinal lymph nodes.Eight cases underwent PET/CT imaging and one underwent MR imaging,respectively.Independent sample t test was used to compare difference in ages between ACC group and MEC group.Nonparametric test was performed to compare difference in tumor's diameter between ACC group and MEC group.Comparison of genders,history of smoking,tumor-node-metastasis (TNM) stage and CT features between ACC group and MEC group were tested using Fisher's exact tests.Survival was calculated using the Kaplan-Meier method,and the survival curves were compared by the log-rank test.Results Compared to MEC,patients with ACC were older.There were significant difference between the two groups (t=3.154,P<0.05).ACC tended to involved trachea or main bronchi (13/14) while MEC were mostly located at lobar or segment bronchi (6/10).The shape of ACC tumors were mainly lobulated or presented as circumferential wall thickening (13/14),while MECs were smoothly oval (7/10).On contrast-enhanced CT scans,ACC mainly showed mild or moderate enhancement (9/10),While most of MEC had shown avid enhancement (8/10).CT findings suggestive of airway obstructive disease were seen more with MEC (9/10) than ACC (4/14).There were significant differences of the above CT features between ACC and MEC group (P<0.05).A case of EMC in an 43 years old female presented rounded nodule in tracheal;The SUVmax in 6 of 8 cases of PET/CT exceeded 2.2;Overall survival (OS) was 87.5% in all cases.No significant difference was found between ACC and MEC groups regarding OS (x2=0,P=1.000).Ages,surgical and nonsurgical patients and TNM stage were found to be related to OS (x2=13.799,13.799,13.171,respectively,P<0.05).Conclusions Primary central airway salivary gland-type tumors are commonly occurred in patients at a low age,with weak invasive feature and good prognosis.The predominant site and CT characteristics between ACC and MEC were significantly different.

ABSTRACT

Objective To compare the clinical efficacy and safety with statin and ezetimibe in the treat-ment of ACS after PCI. Methods 126 patients with acute coronary syndrome(ACS)who underwent percutaneous coronary intervention(PCI )were divided into three groups according to the lipid-lowering strategy. group A:mod-erate-intensity statin group(n = 47),group B:Ezetimibe combined with moderate-intensity statin(n = 38), group C:Fortified statin(n = 41). The levels of serum lipids,liver enzymes,creatinine,creatine kinase(CK), and the compliance ratio of lipids were compared between the three groups at 1 month and 6 months after PCI re-spectively. All patients were followed up for 12 months,then reviewing coronary angiography and comparing MACE incidents within 12 months. Results The levels of cholesterol in group A,group B and group C decreased signifi-cantly(P < 0.05)at one month after PCI,the percentage of decrease of TC in three groups was 18.95%,35.61%and 19.84% and 24.89%,and LDL-C was 39.56%,23.99%,respectively. The percentage of TC and LDL-C in group B were significantly lower than those in other two groups(all P < 0.05). One months after PCI,the compli-ance rate of LDL-C in group B(65.8%)was higher than that in A group(34.0%)and C group(31.7%),P <0.05. Six months after PCI,the compliance rate of LDL-C in group B( 91.3% )was still significantly higher than that in group A(79.4%)and group C(84.2%),but P > 0.05. The incidence of MACE in group B was significant-ly lower than that in group A and C(P < 0.05)at 12 months after PCI,while the incidence of side effects in group C was significantly higher than that in group B and group A(P < 0.05). The incidence of neovascular steno-sis in group B was lower than that in group A and C(all P < 0.05). There was no significant difference in the intra-ventricular restenosis among the three groups(all P > 0.05). Conclusions Ezetimibe-statin combination therapy reduced TC and LDL-C levels more significantly than statin alone(including moderate-intensity statin therapy and strengthen statin therapy),and the compliance rate of LDL-C at 1 month after PCI was significantly higher than that of statin alone. The incidence of MACE was lower in combination group than in statin group at 12 months after operation,and the side effects were less. Above all,the combination of statin and ezetimibe may be the secondary prevention for CHD in patients with acute coronary syndrome after PCI.
