Objective Flexible ureteroscopic holmium laser lithotripsy for the treatment of calculi in caliceal diverticulum complicated with perirenal hematoma has a low incidence.This paper discusses the clinical features and preventive strategies of the disease. Case Presentation The patient was a 58-year-old male, admitted due to repeated left lower back pain for two months. CT scan indicated left calyceal diverticulum stones. Transurethral flexible ureteroscopic holmium laser lithotripsy was performed. A follow-up CT scan revealed a left perirenal hematoma and the stones had shifted to the perirenal area. Percutaneous nephrolithotripsy was then performed. Four weeks after surgery, CT scan showed that the left perirenal hematoma had absorbed well. Conclusion The risk of perirenal hematoma and stone displacement may occur during ureteroscopic holmium laser lithotripsy for calyceal diverticulum stones. The risk can be effectively reduced by negative suction sheath, reduction of intraoperative perfusion pressure, reasonable use of holmium laser, and control of related factors.

We report a 30-year-old woman who presented with intermittent gross hematuria and left flank pain，and CT revealed a left staghorn stones. The initial percutaneous nephrolithotomy（PCNL）left a 6 mm fragment，and both stone and urine cultures yielded extended-spectrum β-lactamase（ESBL）-producing Escherichia coli. Seven months later，the stone increased to 6 cm and urine culture revealed Proteus mirabilis. Endoscopic combined intrarenal surgery（ECIRS）achieved complete clearance. At 6-month follow-up，the patient remained asymptomatic，culture-negative，and stone-free. This case highlights that small residual fragments after PCNL may rapidly enlarge with secondary urease-producing infection，underscoring the need for early re-intervention and standard follow-up.

Objective Evaluation of the efficacy of high-frequency repetitive transcranial magnetic stimulation for chronic disturbance of consciousness after severe craniocerebral injury based on magnetic resonance spectroscopy.Methods The clinical data of 106 patients with chronic disturbance of consciousness after severe craniocerebral injury from January 2018 to December 2022 were retrospectively analyzed,and they were divided into control group(conventional rehabilitation treatment)and observation group(high frequency repetitive transcranial magnetic stimulation treatment)by propensity score matching method(1∶1),with 53 cases in each group.Both groups were examined by magnetic resonance spectroscopy(MRS)before and after treatment.The brain metabolic indexes[N-acetyl aspartate(NAA)/creatine(Cr)value,choline complex(Cho)/Cr value],Glasgow coma scale(GCS)score,electroencephalogram(EEG)grading,coma recovery scale(CRS-R)score,brainstem auditory evoked potential(BAEP)grading,upper limb sensory evoked potential(SSEP)grading and Cerebral blood flow perfusion index[cerebral blood volume(CBV),mean transit time(MTT),cerebral blood flow(CBF)]were compared between the two groups.Results After treatment,the NAA/Cr values of the thalamus and brainstem in the two groups increased,while the Cho/Cr values decreased,and the levels of brain metabolic indexes in the observation group were signifi-cantly better than those in the control group(P<0.05).The two groups'GCS score and CRS-R score increased,and the improvement of the observation group was better than that of the control group(P<0.05).The BAEP grading,EEG grading,and SSEP grading of the two groups improved,and those of the observation group were better than the control group(P<0.05).The CBF and CBV of the two groups increased,and MTT decreased,and the level of cere-bral blood perfusion index in the observation group was better than that in the control group(P<0.05).Conclusion High frequency repetitive transcranial magnetic stimulation has a significant effect on the recovery of patients with chronic consciousness disorders after severe craniocerebral injury.The mechanism may be related to improving the blood flow velocity of brain tissue and metabolism in the brain.

Objective:To explore the effect of empathy nursing intervention on negative emotion, sleep quality and health literacy of patients with pulmonary tuberculosis.Methods:A total of 77 patients in Department of Infectious Diseases of People′s Hospital of Leshan from June 2019 to September 2020 were divided into intervention group ( n=39) and control group ( n=38) by random digits table method. The patients in the control group were given routine nursing, and the patients in the intervention group were given empathy nursing intervention on the basis of routine nursing. Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Pittsburgh Sleep Quality Index (PSQI) and Health Literacy Management Scale (HeLMS) were used before and 12 weeks after intervention to evaluate the effects. Results:There was no significant difference in the total scores of HAMD, HAMA, PSQI and HeLMS between the two groups before intervention ( P>0.05), but after intervention, the scores of HAMD and HAMA in the intervention group were 10.64 ± 1.86, 12.64 ± 2.12, lower than those in the control group (14.63 ± 2.19, 15.11 ± 2.71). The differences were statistically significant ( t=-8.63, -4.46, P<0.05). The total score of PSQI and the scores of daytime dysfunction, use of hypnotic drugs, time of falling asleep, time of sleep, sleep quality, sleep disorder and sleep efficiency in the intervention group were 10.26 ± 1.65, 1.22 ± 0.22, 1.48 ± 0.23, 1.51 ± 0.27, 1.45 ± 0.26, 1.57 ± 0.22, 1.54 ± 0.21,1.49 ± 0.24, lower than those in the control group (13.07 ± 2.14, 1.92 ± 0.31, 1.75 ± 0.34, 1.95 ± 0.29, 2.02 ± 0.33, 1.84 ± 0.31, 1.72 ± 0.27, 1.87 ± 0.29). The differences were statistically significant ( t values were -11.45--3.27, all P<0.05). The total score of HeLMS and the scores of information acquisition, communication and interaction, and health improvement intention in the intervention group were 96.12 ± 14.71, 37.87 ± 5.83, 35.91 ± 5.13, 16.21 ± 2.53, higher than those in the control group (86.35 ± 14.12, 33.17 ± 5.27, 32.87 ± 5.42, 14.16 ± 2.19). The differences were statistically significant ( t values were 2.53-3.80, all P<0.05). Conclusions:Empathy nursing intervention can effectively alleviate the negative emotions of pulmonary tuberculosis patients, improve their sleep quality, and improve their health literacy level.

Objective To investigate the immune reaction mechanism of NLRP3 inflammsome in the Escherichia coli bloodstream infection. Methods C57BL/6 mouses were injected by caudal vein with Escherichia coli and phosphate buffer ( PBS) respectively as injected group and control group. The infected group mice were executed after 24 hours and 48 hours,and the control group mice were executed at the beginning of experiment,taking the tis-sue samples of the two groups and detecting the changes of each index. The changes of the indexes were detected by enzyme-linked immunosorbent assay( ELISA) , real-time quantitative PCR ( RT-qPCR) , Western blot and HE stai-ning. Results Significant inflammatory cell infiltration and tissue necrosis were observed by HE staining in 24 h and 48 h after infection with Escherichia coli. The IL-1β and IL-18 cytokines in tissue homogenate and serum of bloodstream infection group were all increased significantly. The mRNA expression of NLRP3, ASC and caspase-1 in liver and lung homogenate increased significantly at 24 h after infection, while NLRP3, ASC and caspase-1 mR-NA in kidney homogenate increased significantly at 48 h after infection. The expression of NLRP3 protein and ASC protein in the liver, lung and kidney tissues of the 48 h group was significantly higher than that in the 24 h group, but there was no significant difference in pro-caspase-1 expression of liver and kidney tissues between three groups. The expression of NLRP3 protein and ASC protein in liver, lung and kidney tissues in 48 h group was significantly higher than that in 24 h group,the expression of pro-caspase-1 protein in liver and kidney tissue in three groups dis-played no significant difference,the expression of caspase-1 protein in lung and kidney tissues was increased with time. Conclusion Escherichia coli bloodstream infection is associated with the activation of NLRP3 inflammatory, and the expression level of NLRP3 inflammasome was related to the severity of infection, with the increase of infec-tion, NLRP3 inflammatory expression increased. The findings may provide a new idea for the treatment of sepsis caused by Escherichia coli bloodstream infection.

Objective To investigate the diagnostic value of dynamic-extended focused assessment with sonography for trauma (D-EFAST) in patients with multiple trauma in intensive care unit (ICU). Methods A prospective clinical study was conducted. Eighty patients with multiple trauma admitted to ICU of Anhui Provincial Hospital from September 1st, 2014 to December 31st, 2016 were enrolled. Extended focused assessment with sonography for trauma (E-FAST) check was conducted at first, for those who had positive findings diagnosis was confirmed by immediately CT examination or surgical exploration. If it was negative, the patients received E-FAST every morning for 7 days (defined as D-EFAST), for those with positive findings, immediately CT or surgery was performed to clarify the diagnosis. The final clinical diagnosis was used as the "gold standard" to calculate the diagnostic accordance rate of EFAST and D-EFAST examination technique for pneumothorax, pleural effusion, spleen injury, kidney damage, liver damage, gastrointestinal injury, pericardial effusion, bladder rupture, and pancreatic injury, as well as their sensitivity, specificity, positive predictive value, negative predictive value, accuracy rate, and missed diagnosis rate, and the difference between EFAST and D-EFAST was compared. Results There were 4 patients excluded because of death and abandoning treatment, and finally 76 patients were included in the study. The total sensitivity of E-FAST examination technique for pneumothorax, pleural effusion, spleen injury, liver damage, gastrointestinal injury, pericardial effusion, and bladder rupture was 75.9% (66/87), and the specificity was 98.3% (587/597), the positive predictive value was 86.8% (66/76), and the negative predictive value was 96.5% (587/608), the accuracy rate was 95.5% (653/684), and the rate of missed diagnosis was 24.1% (21/87). The most of the delayed injury in patients with multiple trauma occurred at 2-7 days after injury with incidence of 4.8% (33/684). The diagnostic sensitivity of D-EFAST for delayed injury was 98.3% (118/120), the specificity was 99.8% (563/564), the positive predictive value was 99.2% (118/119), the negative predictive value was 99.6% (563/565), the diagnostic accuracy rate was 99.6% (681/684), and rate of missed diagnosis was 1.7% (2/120). When the final clinical diagnosis was set as the "gold standard", D-EFAST technology for the detection rate was 98.3% (118/120) for patients with multiple trauma on organ injury while the detection rate of E-FAST was 75.9% (66/87), with statistical significant difference (P < 0.01), indicating that D-EFAST was better than E-FAST in check of multiple trauma patients with organ injury. Conclusion Although the E-FAST technology can quickly diagnose the multiple trauma patients and win the rescue time for critical patients, multiple trauma patients injured after 2-7 days prone to delayed damage and are difficult to detect, and D-EFAST can be used to find delayed damage earlier, and reduce the misdiagnosis rate of multiple trauma patients.

BACKGROUND/AIMS: This study was to investigate whether transforming growth factor-β1 (TGF-β1) plays a role in hyperalgesia in chronic pancreatitis (CP) and the underlying mechanisms. METHODS: CP was induced in male adult rats by intraductal injection of trinitrobenzene sulfonic acid (TNBS). Abdominal hyperalgesia was assessed by referred somatic behaviors to mechanical stimulation of rat abdomen. Dil dye injected into the pancreas was used to label pancreas-specific dorsal root ganglion (DRG) neurons. Whole cell patch clamp recordings and calcium imaging were performed to examine the effect of TGF-β1 on acutely isolated pancreas-specific DRG neurons. Western blot analysis was carried out to measure the expression of TGF-β1 and its receptors. RESULTS: TNBS injection significantly upregulated expression of TGF-β1 in the pancreas and DRGs, and TGF-β1 receptors in DRGs (T9-T13) in CP rats. Intrathecal injection of TGF-β receptor I antagonist SB431542 attenuated abdominal hyperalgesia in CP rats. TGF-β1 application depolarized the membrane potential and caused firing activity of DRG neurons. TGF-β1 application also reduced rheobase, hyperpolarized action potential threshold, and increased numbers of action potentials evoked by current injection of pancreas-specific DRG neurons. TGF-β1 application also increased the concentration of intracellular calcium of DRG neurons, which was inhibited by SB431542. Furthermore, intrathecal injection of TGF-β1 produced abdominal hyperalgesia in healthy rats. CONCLUSIONS: These results suggest that TGF-β1 enhances neuronal excitability and increases the concentration of intracellular calcium. TGF-β1 and its receptors are involved in abdominal hyperalgesia in CP. This and future study might identify a potentially novel target for the treatment of abdominal pain in CP.

Objective To summarize the clinical experience of surgical intervention for cardiac neoplasm in a fetus . Methods A 32-year-old pregnant woman was admitted to our hospital for complaint of fetal cardiac neoplasm .A separated het-erogenic cardiac occupying lesion was identigied at right atrium of the fetus by echocardiography , whose size is 2.85 cm ×2.25 cm, but the pathogenic origin still remained uncertain, maybe originate from ether pericardium or atrium.The annulus of tri-cuspid valve was compressed nearly 50% with the presence of amount of pericardial effusion.The fetal heart rate decreased at some fetal position resulting in the compression to the heart.So an Ex-utero Intrapartum Therapy(EXIT) procedure was per-formed under the supply of placenta at the 32 weeks of pregnancy.Cesarean section was performed with intact umbilicus and fe-tal circulation by obstetricians.Consequently, the median sternotomy of this fetus and pericardiotomy were performed , with 30 ml clear pericardial effusion drained .The tumor was confirmed to be giant right atrial neoplasm after the intraoperative explora-tion.Considering on the high risk of the cardiopulmonary bypass and limited time for EXIT , the giant atrial neoplasm was left alone with delayed sternum closure after the effectively decompression of the heart .The omphalotomy was successfully per-formed after the EXIT surgery.The neoplasm resection and the repair for its defect on right atrium were performed with cardiop-ulmonary bypass 2 days later.Results Convalesce of this mother was quite good after cesarean resetion .Hemodynamics of the premature baby was satisfatory after the resection of right atrial neoplasm which pathological report was benign hemangioma . Conclusion Via multiple disciplines collaboration , EXIT intervention for fetus is feasible and safe under adequate prepara-tion.

The protective effects of diallyl trisulfide on liver were examined in rats with sepsis. Sepsis was reproduced in rats by cecum ligation and puncture (CLP). Fifty-six male Wistar rats were randomly divided into sham-operated group (group S, n=8), sepsis model group (group C, n=24), diallyl trisulfide (DATS)-treated group (group D, n=24). Animals in groups C and D were further divided into three subgroups according to different observation time points, with 8 rats in each subgroup· Rats in group D and C were intravenously injected with normal saline or DATS respectively at a dose of 20 mg/kg after the establishment of sepsis model. Eight rats in groups C and D were sacrificed at 3, 6 and 24 h post-CLP and their livers were harvested for detection of interleukin (IL)-1 receptor associated kinase-4 (IRAK-4), nuclear factor-κB (NF-κB), c-fos, c-jun, malondialdehydethhe (MDA) and superoxide dismutase (SOD), tumor necrosis factor alpha (TNF-α) and for pathological examination. The results showed that the levels of serum IRAK-4, NF-κB and TNF-α in hepatic tissues were higher in group C than group S (control group) (P<0.05). After DATS treatment, the levels of IRAK-4 and NF-κB in the hepatic tissues and serum TNF-α in group D were lower than those in group C (P<0.05). The levels of c-fos and c-jun and MDA in the hepatic tissues were higher in group C than in group S (P<0.05). After DATS treatment, the levels of c-fos and c-jun and MDA in the hepatic tissues were significantly lower in group D than in group C (P<0.05). When compared with group S group, concentration of SOD in the hepatic tissues in group C was significantly lower (P<0.05). After DATS treatment, the concentration of SOD in the hepatic tissues was higher in group D than in group C (P<0.05). These findings suggested that treatment with DATS could ameliorate sepsis-induced liver injury in rats. The protective effect might be related to its ability to inhibit the signal pathway of IRAK-4 and NF-κB, thereby decreasing the production of oxygen free radicals and down-regulating the expression of c-fos and c-jun.
