Objective To investigate the effects and mechanism of prone ventilation in rats with lipopolysaccharide(LPS)-induced extra pulmonary acute lung injury(ALI). Methods Thirty-two male Sprague-Dawley(SD)rats were randomly divided into four groups:control group,ALI group,supine position group(ALIS group)and prone position group(ALIP group). The ALI animal model was reproduced by intra-peritoneal injection of LPS 6 mg/kg,and 2 mL/kg sterile saline was intra-peritoneally injected in control group. After 24 hours,the ALIS group and ALIP group were mechanically ventilated for 4 hours in supine and prone positions respectively. Arterial partial pressure of oxygen(PaO2),carbon dioxide partial pressure(PaCO2),wet to dry weight ratio of lung(W/D) were observed,and the levels of tumor necrosis factor-α(TNF-α),interleukins(IL-6,IL-10)in bronchoalveolar lavage fluid(BALF)were measured. The degrees of histopathological changes of lung were investigated and assessed under light microscope. Results Compared with control group,PaO2 was significantly lower in ALI,ALIS and ALIP groups〔mmHg(1 mmHg=0.133 kPa):68±7,82±8,93±7 vs. 116±7〕,and the PaCO2 in ALI and ALIS groups was obviously higher(mmHg:53±6,51±5 vs. 43±7,both P<0.05);lung W/D ratio as well as levels of TNF-α, IL-6 and IL-10 in BALF were significantly higher in ALI,ALIS and ALIP groups〔lung W/D ratio:5.11±0.32, 4.71±0.38,4.53±0.45 vs. 4.48±0.15,TNF-α(ng/L):548±82,431±64,347±53 vs. 162±16,IL-6(ng/L):772±119,587±178,490±139 vs. 127±16,IL-10(ng/L):211±43,295±36,352±59 vs. 104±31,all P<0.05〕. Compared with ALI group,PaO2 in ALIS and ALIP groups was significantly higher,and in ALIP group,PaCO2 was lower,lung W/D ratio,TNF-α and IL-6 in BALF were obviously lower,while IL-10 in BALF was obviously higher(all P<0.05). Compared with ALIS group,the changes in ALIP group were more significant(all P<0.05). Compared with ALIS group,under light microscope,it was shown that the hyper-inflated areas were less,normal and collapsed areas were greater on the ventral side,and the collapsed area was less and the normal ventilation area was greater on the dorsal side in ALIP group(all P<0.05). Conclusion In rats with LPS-induced extra pulmonary ALI,the prone ventilation can improve gas exchange,promote uniform distribution of ventilation,decrease pulmonary edema and in the mean time attenuate inflammatory response.

Objective To investigate the significance of galactose galectin-3(Galectin-3)and matrix metalloproteinase-2(MMP-2)expression in gliomas patients and thire role in process of gliomas' malignancy development. Methods Immunohistochemistry was used to detect Galectin-3 and MMP-2 protein expression in 5 normal brain tissue and 40 patients with different grade gliomas. According to positive cells number of Galectin-3,MMP-2 in tumor cells under a microscope,to determine the expression,and the positive index(LI)which came from the percentage of the positive cell number out of the total cell number was to expressed the number of positive cell. Results Galectin-3 and MMP-2 protein expression in normal brain tissue were negative. In glioma tissues,Galectin-3 was mainly expressed in the cytoplasm and membrane of tumor cells. In 23 glioma tissue withⅠor Ⅱ grade,9 cases(39. 13% )was positive and the LI values was(5. 65 ± 3. 47)% in terms of Galectin-3 expression. In Ⅲ,Ⅳ grade glioma specimens,the positive rate of Galectin-3 expression was 76. 47%(13 / 17), and LI value was(27. 88 ± 22. 13)% . The difference of Galectin-3 expression and LI value were significant between specimens with Ⅰ,Ⅱ grade and Ⅲ,Ⅳ significant( χ2 = 4. 101,t = 4. 105;P < 0. 05). In human gliomas,MMP-2 expression protein was mainly expressed in tumor cells and vascular basement membrane of the endothelial cell cytoplasm. In 23 glioma tissue with Ⅰor Ⅱ grade,9 cases(39. 13% )was positive and the LI values was(5. 91 ± 4. 78)% in terms of MMP-2 expression. In Ⅲ,Ⅳ grade glioma specimens,the positive rate of MMP-2 expression was 88. 24%(15 / 17),and LI value was(30. 06 ± 22. 94)% . The difference of MMP-2 expression was significant between specimens with Ⅰ,Ⅱ grade or Ⅲ,Ⅳ grade( χ2 = 7. 882,t = 4. 271;P< 0. 05). The linear correlation analysis showed that there was positively correlation between Galectin-3 and MMP-2 positive cells(r = 0. 800,P < 0. 05). Conclusion Galectin-3 and MMP-2 protein expression in Ⅰ,Ⅱgrade gliomas is significantly lower than those inⅢ,Ⅳ grade glioma,and they are positively related with the progress of malignant gliomas. Galectin-3 and MMP-2 protein can be used to evaluate or judge the malignant stage of human brain glioma.

Objective To investigate the effects of electroacupuncture (EA) on the implementation of blind nasojejunal (NJ) tube placement and enteral nutrition (EN) in neurosurgical severe coma patients in intensive care unit (ICU).Methods Seventy-nine neurosurgical severe coma patients admitted to ICU were randomly divided into conventional group (blind NJ tube placement,n =40) and EA group (NJ placement and EA,n =39).EA was performed after NJ tube placement at bilateral acupoints Zusanli (ST36) and Hegu (L14) points using EA treatment instrument.The impelling distance of NJ tube were measured and the success rate of NJ tube placement were calculated.The postoperative complications were observed.Results The difference of NJ tube impelling distances at the 24th,48th,and 72th hours after surgery in EA group were significant longer than that in conventional group (P ＜ 0.05).The success rates of NJ tube placement at the 24th and 72nd hours after surgery in EA group were significantly better than that in conventional group (P ＜ 0.05).Their EN calories qualifiedness rate in 72 hours also increased significantly compared with conventional group and the proportion of patients assisted with parenteral nutrition decreased (P ＜0.05).The postoperative complications including alimentary tract hemorrhage,vomiting,and abdominal distension decreased remarkably in EA group compared with conventional group (P ＜ 0.05).Conclusions EA stimulation at acupoints could promote the gastrointestinal peristalsis of neurosurgical severe coma patients and elevate the success rate of blind NJ tube placement,so it is beneficial for the implementation of early enteral nutrition (EEN).

Objective To analyze the associations of the interleukin-10 (IL-10) promoter-1082G/A and-819C/T single nucleotide polymorphism (SNP) and serum level of IL-10 with intracranial aneurysm (IAs). Methods The polymerase chain reaction (PCR) and DNA direct sequencing methods were used to detect IL-10 gene promoter district two SNP site,-1082G/A and-819C/T genotype frequency and allele frequency in 206 patients with IAs and 187 controls. Chi-square test was used to analyze differences between two groups. The serum level of IL-10 was analyzed by ELISA, and t-test was used to analyze significant differences between two groups. Results There were significant differences in genotypes of GG and GA+AA, as well as the alleles G and A, in-1082G/A locus between IAs group and control group (P<0.01). There were higher frequencies of genotype GA+AA and the allele A in IAs group than those in control group (P<0.01). There was higher risk of suffering IAs in patients with genotype GA+AA (OR=4.137, 95%CI:2.476-6.914) and the allele A (OR=3.368, 95%CI:2.476-4.583). There were higher frequencies of the genotype CT+TT and the allele T in-819C/T locus in IAs group than those of control group (P<0.01). There was higher risk of suffering IAs in patients with genotype CT+TT (OR=3.393, 95%CI:1.952-5.900) and the allele T (OR=3.764, 95%CI:2.730-5.192). The serum level of IL-10 was significantly lower in IAs group than that of control group (P<0.01). Conclusion The IL-10 promoter SNP influences the expression of IL-10. IL-10 promoter-1082G/A and-819C/T polymorphisms are correlated with the formation of IAs.

Objective To investigate the patterns of change in thyroid functional parameters ( serum TSH,FT3, and FT4 ) in patients with papillary thyroid cancer (PTC) before and after the initial 131I treatment for thyroidal remnant ablation. Methods Seventy-four PTC patients, treated with 3.7 GBq 131 I therapy, were divided into two groups, group A with serum TSH＜30 mIU/L and group B with serum TSH ≥30 mIU/L the day before 131I treatment. Five days after the treatment, the patients were re-examined for serum FT3, FT4, and TSH levels.Results In group A (22 cases), 5 days after the 131I ablation treatment, FT4significantly increased by 88% and FT3 by 87%, while TSH decreased by 87% (all P＜0. 05 ), and 45% (10/22)cases manifested the signs of transient thyrotoxicosis. In group B (52 cases)after treatment, individual variance of FT3 and FT4 was obvious,with FT4 decreased by 13% and FT3 decreased by 14% ( both P＜0. 05 ), while TSH slightly increased by an average of 6% ( P＞0.05 ). Conclusion After the initial 131 I ablation therapy for thyroidal remnant, the thyroid hormone levels in some PTC patients significantly increase while in others may slightly decrease in the early stage. The supplementary and suppressive therapy after 131I ablation for PTC patients might be individualized depending on the thyroid hormone determination.

Objective:To analyze the cause of varicocele (VC) recurrence and investigate the efficacy of sub-inguinal microsurgical varicocelectomy (MV) for recurrent VC.Methods:All of 16 inpatients diagnosed as recurrent VC, in the Department of Andrology of the Affiliated Hospital of Qingdao University from 2015 April to 2019 April, were performed sub-inguinal MV. The age of the inpatients was 18-36 years old, median 27 years old.5 cases were originally performed retroperitoneal high ligation of spermatic vein and other 11 cases were originally performed laparoscopic varicocelectomy. During the review one to three years after the previous operation, all of 16 patients were diagnosed as VC recurrence. The complains of these patients during the review included male subfertility (10 cases) and scrotal pain (12 cases), in which 6 cases’ complains were male subfertility with scrotal pain. After admission, 13 patients were classified as Grade Ⅲ (left in 8 cases, bilateral in 5 cases) and 3 patients as Grade Ⅱ (all left). The median of their visual analogue scale (VAS) was 2.5. Color doppler flow imaging (CDFI) grading showed: Grade Ⅲ in 12 cases (left in 7 cases, bilateral in 5 cases), Grade Ⅱ in 4 cases (all left). Particularly, 12 of them were Graded as Ⅲ simultaneously accompanying with Nut-cracker Phenomenon (NCP). Preoperative tests showed that the average serum testosterone was (16.2±4.9)nmol/ml, the average sperm concentration was (11.8±3.9)×10 6/ml and the progressive motility rate (PR) was (24.4±4.2)%. All of the patients were performed sub-inguinal MV using general anesthesia and supine position. The spermatic cords were clearly exposed and padded up by inserting gauze strips under them. During the operation, the field was magnified 4-6 times with the microscope. Then all of the dilated external and internal spermatic veins were ligated, at the same time the internal spermatic artery and lymph vessels were well preserved. During these operations, 11 patients underwent left-side MV, while other 5 did bilateral MVs. During these MVs, we found twisted and dilated external and internal spermatic veins in all cases and well preserved the internal spermatic arteries and lymph vessels. The number of ligated left and right external spermatic veins were(2.1±0.6) and (1.4±0.5)respectively and the number of ligated left and right internal spermatic veins were (10.1±1.1) and (6.6±0.5) respectively. We also found out(1.3±0.5) internal spermatic arteries and (3.0±1.0)lymph-vessels on left side. On right side, there were (1.4±0.5) internal spermatic arteries and (2.6±0.5) lymph-vessels respectively. At last, we summarily analyzed the pre-operative and post-operative VAS, serum testosterone, CDFI and semen analysis data. Results:All of the 16 sub-inguinal MVs were successfully performed. All patients were reviewed comprehensively 6 months after MV. The reviewed results showed that the post-operative VAS was significantly reduced ( Z=-2.994, P<0.05), palpable scrotal vessels disappeared and Valsalva tests were negative. No obvious reflux of internal spermatic veins were detected by CDFI. Interestingly, the sperm concentration and motility were both significantly improved 6 months after MV ( P<0.05), while there was not remarkable increase of the serum testosterone after MV ( P>0.05). During the follow up, no testicular atrophy, hydrocele and other complications were found. Up to submission, five of the ten patients who presented for male subfertility have impregnated their wives. Conclusions:The most possible cause of VC recurrence could be the omission of the external and internal spermatic veins, particularly in the grade Ⅲ VC patients or VC accompanied with NCP. The sub-inguinal MV, which can discover more twisted spermatic veins and at the same time preserve the spermatic artery and lymph-vessels, shows better clinical efficacy than other procedures.

Objective:To explore the application of folding transfer shelf in the transportation of critically ill patients.Methods:Patients transferred from the emergency department to the intensive care unit (ICU) admitted to the First Hospital of Jiaxing from January 1st to December 31st in 2019 were enrolled. The patients were divided into study group and control group by whether or not using the self-developed folding transfer shelf. The incidence of adverse events, the stability rate of vital signs and the transport time were compared between the two group.Results:A total of 437 patients were enrolled in the study, with 222 in the study group (which used the self-developed folding transfer shelf) and 215 in the control group (which used the conventional stretcher). The baseline data such as gender, age, disease status and disease severity were balanced between the two groups. The stability rate of vital signs in the study group was higher than that in the control group (89.19% vs. 82.33%, P < 0.05). The transfer time in the study group was shorter than that in the control group (minutes: 6.39±1.35 vs. 7.61±1.34, P < 0.01). The total incidence of adverse transport events in the study group was lower than that in the control group (2.25% vs. 10.23%, P < 0.01). The incidence of miscarriage of emergent materials and instrument falling in the study group were lower than those in the control group (0% vs. 2.79%, 0% vs. 2.33%, both P < 0.05). Conclusions:The folding transfer shelf could reduce the transport risk of critical ill patients, especially the risk of miscarriage and falling of rescue instrument. The application of folding transfer shelf could regulate the management of transport, keep the vital signs of patients stable during transport, shorten the transport time, and facilitate an efficient and high-quality transport.

Objective: To examine the effects of obesity and central obesity on hypertension, so as to provide insights into the prevention and control measures of hypertension. Methods: From September to December 2018, residents at ages of 35 to 75 years were sampled using the multi-stage random sampling method in Baiyin District, Baiyin City, Gansu Province, and subjected to questionnaire surveys and physical examinations. The interaction between obesity/central obesity and hypertension was evaluated using logistic regression analysis. The synergy index ( SI ), relative excess risk due to interaction ( RERI ) and attributable proportion due to interaction ( AP ) were calculated using Excel compiled by Andersson et al. Results: A total of 6 246 questionnaires were allocated and 6 169 valid questionnaires were recovered, with an effective recovery rate of 98.77%. The respondents included 3 038 men ( 49.25% ) and 3 131 women (50.75%), with a mean age of ( 52.05±8.78 ) years. There were 832 respondents with obesity ( 13.49% ) and 2 278 with central obesity ( 36.93% ). The crude and standardized prevalence rates of hypertension were 35.89% and 33.05%, respectively. Multivariable logistic regression analysis showed that obesity ( OR=2.020, 95%CI: 1.705-2.393 ) and central obesity ( OR=1.622, 95%CI: 1.433-1.836 ) were statistically associated with hypertension. There was no multiplicative interaction between obesity or central obesity and hypertension ( OR=1.011, 95%CI: 0.655-1.560 ), and no additive interaction was detected between obesity or central obesityand hypertension ( SI=1.405, 95%CI: 0.815-2.424; RERI=0.658, 95%CI: -0.298 to 1.614; AP=0.201, 95%CI: -0.075 to 0.476 ). Conclusions Obesity and central obesity increase the risk of hypertension; however, no interaction is detected between obesity or central obesity and hypertension.
