Objective To investigate the application of intra pelvic pressure(IPP)in ultramicro-channel percutaneous nephrolithotripsy.Methods From January 2022 to January 2023,60 patients with urinary calculi who needed Super mini-PCNL(SMP)in The First Hospital of Jiaxing selected as the study objects.According to random number method,the patients were divided into control group and experimental group,with 30 cases.Both groups were treated with ultra-micro channel percutaneous nephrolithotripsia,while the experimental group was monitored and regulated IPP in real time during the operation,and observed and compared clinical indicators,IPP,fever,urinary protein,renal function,hemoglobin(Hb)and adverse reactions between the two groups.Results Compared with the control group,the hospitalization time of experimental group was shortened and the stone clearance rate was increased(P<0.05).The IPP levels of experimental groups at 6min,12min,24min and 36min were lower than those of control group(P<0.05).The fever of experimental group was lower than that of control group at 2d,3d,4d and 5d after operation(P<0.05).The urinary protein level of experimental group was lower than that of control group at 1d,2d,3d and 4d after operation(P<0.05).Compared with control group,blood urea nitrogen(BUN)and serum creatinine(SCr)levels of experimental group were decreased,and Hb levels were increased(P<0.05).The incidence of adverse reactions in experimental group was lower than that in control group(P<0.05).Conclusion Monitoring and adjusting intrapelvic pressure during super-mini percutaneous nephrolithotomy is beneficial in reducing postoperative fever in patients with urolithiasis,reducing urinary protein expression and kidney function damage,and controlling the occurrence of adverse reactions.It is worth recommending.

Objective:To explore the relationship between proactive personality, resilience and achievement motivation of military cadets, and to explore the mediating role of resilience between proactive personality and achievement motivation, as well as the moderating effect of cadets’leading ability on this mediating role.Methods:In this study, 109 military cadets were measured with proactive personality scale, Connor-Davidson resilience scale (CD-RISC) and achievement motivation scale. SPSS 26.0 was used for descriptive statistical analysis and correlation analysis.Results:①There was a significant correlation among the total scores of proactive personality, resilience and achievement motivation ( Ps<0.01). ②Proactive personality could significantly predict the level of achievement motivation ( a=0.454, P<0.001), and resilience could significantly predict the level of achievement motivation ( b=0.231, P=0.019). ③Resilience significantly mediated the relationship between proactive personality and achievement motivation ( c′=0.3, P=0.003). ④Cadets' leading ability moderated the effect of resilience on achievement motivation (index=0.338, 95% CI: 0.057 to 0.881). The mediating effect of resilience between proactive personality and achievement motivation was significant for cadets' leaders (Effect=0.381, 95% CI: 0.085 to 1.005), but not significant for other students (Effect=0.043, 95% CI: -0.069 to 0.252). Conclusion:The proactive personality of military cadets can affect the level of achievement motivation through psychological resilience, which is also moderated by cadre identity, suggesting that military education should improve the level of achievement motivation in many ways.

Objective:To investigate the vitamin D level of pulmonary tuberculosis patients in Qinghai Province, and to explore the correlation between vitamin D level and pulmonary tuberculosis.Methods:From May to September 2020, 208 bacterial confirmed pulmonary tuberculosis patients who were admitted to The 4th People′s Hospital of Qinghai Province were enrolled as the pulmonary tuberculosis group, and 129 healthy people who underwent physical examination during the same period were enrolled as the healthy control group. Independent sample t test and chi-square test were used for statistical analysis. Results:The deficiency rate of vitamin D was 11.06%(23/208) in the pulmonary tuberculosis group, which was higher than that (3.10%(4/129)) in the healthy control group, and the difference was statistically significant ( χ2=6.840, P=0.009). The vitamin D level was (56.84±20.03) μg/L in the pulmonary tuberculosis group, which was lower than that ((67.39±17.07) μg/L) in the healthy control group, and the difference was statistically significant ( t=5.154, P<0.01). The vitamin D levels were not different between the newly treated ((56.66±20.02) μg/L)) and retreated pulmonary tuberculosis patients ((59.11±20.81) μg/L) ( t=0.468, P=0.650). The vitamin D level of simple pulmonary tuberculosis patients ((57.82±20.01) μg/L) was higher than that of pulmonary tuberculosis patients combined with other diseases ((48.08±18.46) μg/L), and the difference was statistically significant ( t=2.132, P=0.034). Conclusion:Pulmonary tuberculosis is associated with decreased vitamin D levels, and patients with pulmonary tuberculosis are more likely to suffer from decreased or deficient vitamin D, which suggests clinicians considering the vitamin D status when treating pulmonary tuberculosis patients.

Objective:To compare the therapeutic effects of percutaneous nephrostomy and ureteral stent drainage in the treatment of infectious hydronephrosis.Methods:From June 2017 to June 2018, 92 patients with infectious hydronephrosis in the First Hospital of Jiaxing were selected.The patients' hospital number was entered into the computer and the patients were divided into group A(percutaneous nephrolithotomy and drainage treatment, 46 cases) and group B(transurethral ureteral stent drainage treatment, 46 cases) by lottery.The treatment effect and safety were compared between the two groups.Results:There were no statistically significant differences in age, male/female, duration of disease, site of renal disease, primary disease, and underlying disease between the two groups(all P>0.05). There was no statistically significant difference in the success rate of disposable catheter placement between group A and group B(97.73% vs.100.00%, χ 2=0.126, P>0.05). The efficacy of group A was significantly higher than that of group B(97.73% vs.81.40%, χ 2=4.617, P<0.05). There were no statistically significant differences in the incidence rates of bleeding, infection, drainage tube abscess and puncture abscess between the two groups(all P>0.05). Conclusion:Percutaneous nephrostomy in the treatment of infectious hydronephrosis is more effective than ureteral stent drainage.Both of two methods have high safety of treatment.Clinical treatment should be based on the specific circumstances of the patients to obtain a significant clinical effect.

Objective To observe the effect of modified electroconvulsive therapy (MECT) on au-tobiographical memory and efficacy in schizophrenic patients. Methods Seventy-four patients with schizo-phrenia were randomly divided into study group (38 cases) and control group (36 cases). The study group was treated with MECT for 10-12 times in combination with single antipsychotic drug,while the control group was treated with single antipsychotic drug. Both groups were treated for 12 weeks. All patients were assessed for autobiographical memory before treatment and at the 4th,8th and 12th week after treatment,and the effi-cacy was evaluated by the positive and negative symptom scale (PANSS). Results (1)The response time of autobiographical event memory in the study group at the 4th and 8th weekends after treatment ((2 058. 84 ±200. 06)ms,(1 883. 61±202. 17)ms)were significantly longer those at baseline((1 765. 27±203. 23)ms) and that at the same periods in the control group(( 1 787. 03 ± 192. 82),(1 762. 01± 195. 25)),and the differences were statistically significant(t=6. 346,2. 545;P<0. 05,t=5. 945,2. 630;P<0. 05),but the re-sponse time of autobiographical event memory in the study group at the 12th weekend after treatment was not statistically significant compared with that before treatment (P>0. 05). ( 2) For each time point after treat-ment,the PANSS scores of the study group and the control group were significantly lower than those at base-line (P<0. 05). The PANSS scores of the study group at each time point after treatment((62. 42±7. 22), (49. 32±5. 54),(43. 63±9. 90)) were significantly lower than those of the control group at the same periods ((71. 78±10. 19),(56. 14±5. 95),(49. 28±9. 31)),and the differences were statistically significant ( t=4. 577,5. 108,2. 525;all P<0. 05). The total effective rate of the study group ( 94. 7%) was significantly higher than that of the control group (80. 6%) (χ2=9. 287,P<0. 05). Conclusions MECT is effective in the treatment of patients with schizophrenia,and it has some damage to their autobiographical memory,but the damage is transient and reversible.

Objective To systematically review the efficacy of dexmedetomidine mixed with ropivacaine for brachial plexus block in the patients undergoing upper limb surgery.Methods Medline,PubMed,Embase,Web of Science,Weipu,Wanfang,Zhiwang databases were searched for randomized controlled trials involving the efficacy of dexmedetomidine mixed with ropivacaine for brachial plexus block in patients undergoing upper limb surgery from the date of database establishment up to July 2017,and the trials were published in Chinese or in English.Evaluation indexes included onset time and duration of sensory and motor blocks and analgesia time when used for brachial plexus block.Trials were selected and data were extracted independently by 2 investigators,and meta-analysis was conducted using the Cochrane Collaboration's RevMan 5.3 software.Results Twelve randomized controlled trials were included in our metaanalysis.Compared with control group,the onset time of sensory and motor blocks was significantly shortened,the duration of sensory and motor blocks was prolonged,and analgesia time when used for brachial plexus block was prolonged in dexmedetomidine group (P＜0.01).Conclusion Dexmedetomidine mixed with ropivacaine can be effectively used for brachial plexus block in the patients undergoing upper limb surgery.

Objective To investigate the effects of different values of PEEP on cardiac index (CI), stroke volume variation (SVV) and oxygen transport index (DO2I) in patients monitored by FloTrac/Vigileo system, and to provide some references for the hemodynamic management and improvement of oxygenation for patients. Methods Sixty patients scheduled for elective television (TV) auxiliary thoracoscope radical operation for esophageal cancer were included in this study. Data of CI, SVV and DO2I were observed by the FloTrac/Vigileo system. Changes of CI, SVV and DO2I were recorded after anesthesia induction and turn left side (T0), artificial pneumothorax with 0 PEEP after 5 minutes (T1), artificial pneumothorax with 5 PEEP after 5 minutes (T2), artificial pneumothorax with 10 PEEP after 5 minutes (T3), and artificial pneumothorax with 15 PEEP after 5 minutes (T4). Results Compared with T0, CI decreased and SVV increased significantly at T1, T2, T3 and T4(P<0.05). Compared with T1, CI decreased and SVV increased at T4. DO2I increased at T2 and T3 compared with that of T1(P<0.05). Conclusion PEEP may have a certain influence on CI and SVV in the process of operation. The values of 5-10 PEEP can significantly improve oxygenation and have a less influence on hemodynamics, which can be appropriately used in clinical care.

Objective To evaluate whether changes in neonatal intensive care have improved outcomes for extremely low birth weight (ELBW) infants in neonatal intensive care unit (NICU). Methods A prospective phase-lag cohort study was performed in a tertiary level NICU. A meticulous nursing strategy based on neonatal individual developmental care assessment program theory and feasible ELBW minimization stimulus was developed. Conventional care was applied in 2013 (period Ⅰ) and gently caring was applied in 2014 (period Ⅱ). The outcomes of ELBW between these 2 periods were compared. Results During these two periods, thirty-seven infants were included in period Ⅰ and 41 infants in period Ⅱ. In periodⅠ46.0%(17/37) of the infants needed oxygen for at least 28 days, but in period Ⅱ it decreased to 24.4%(10/41), there was significant difference (χ2=3.990, P=0.046). The rate of breastfeeding increased from 27.0%(10/37) in periodⅠto 61.0%(25/41) in period Ⅱ, there was significant difference (χ2=9.061, P=0.003). There was no significant difference in the mortality rate and chronic lung disease (P>0.05). The incidence of intracranial hemorrhage decreased from 21.6%(8/37) to 4.9%(2/41), there was significant difference(P=0.041). Conclusions Gently caring may have resulted in less intracranial hemorrhage and improve breastfeeding rate. Parents are satisfied with gentle care and in light of these findings, gentle care deserves further exploration.

Objective To investigate the effect of remote ischemic preconditioning (RIPC) on the lung injury during one-lung ventilation (OLV) in the patients undergoing thoracic surgery.Methods Eighty patients scheduled for elective radical operation for esophageal cancer,were randomly divided into 2 groups (n=40 each) using a random number table.control group (group C) and group RIPC.At 0 (T1),30 min (T2),1 h (T3) and 2 h (T4) of OLV,blood samples were obtained from the radial artery for blood gas analysis and determination of plasma concentrations of tumor necrosis factor-α (TNF-α),interleukin-1β (IL-1ββ) and IL-10.Oxygenation index(OI),respiratory index(RI) and PaO2/PAO2 were calculated.Exhaled breath condensate was collected and the pH value was measured.Results Compared with group C,Oxygenation index was significantly increased,and respiratory index was decreased at T2-T4,the plasma concentrations of TNF-α and IL-1β were decreased,and the pH value of exhaled breath condensate was increased at T3-T4,and the plasma concentration of IL-10 was increased at T4 in group RIPC.Conclusion RIPC can inhibit inflammatory responses and reduce airway acidification,thus attenuating the lung injury during OLV in the patients undergoing thoracic surgery.

Objective To investigate the effect of different operation positions on cardiac index (CI) and stroke volume variation (SVV) in the patients monitored by FloTrac/Vigileo system to provide some references for the hemodynamic management and liquid treatment of the patients.Methods Sixty patients scheduled for elective TV auxiliary thoracoscope radical operation of esophageal cancer.The CI and SVV changes were observed by using the FloTrac/Vigileo system.CI,SVV and CVP were recorded at 5 min after anesthesia induction (T0),5 min after converting to the position of head low feet high (T1),5 min after converting to the position of head high feet low (T2).Results Compared with T0,CI at T1 and T2 was decreased(P＜0.05);compared with T0,SVV at T1 was decreased and CVP was increased;SVV at T2 was increased and CVP was decreased(P＜0.05).Conclusion The operation position change may have a significant impact on the patient's CI,SVV and CVP.Focusing on the corresponding change can provide some references for the intraoperative hemodynamic management and liquid treatment.
