Objective To explore the clinical application of non - invasive sonography in the determination of detrusor thickness in bladder outlet obstruction. Methods Admitted from January 2012 to January 2014, 116 pa?tients with bladder outlet obstruction were selected as observed group, while another 88 patients without bladder outlet obstruction at the same period were selected as control group. The detrusor thickness determined by sonography in the two groups was comparatively analyzed. Results There were significant differences between the two groups in DWT, residual urine volume, urine output, Qmax, PdetQmax and Pdetmax and other indicators (p <0.05). Conclusion Ultrasonic determination of anterior bladder detrusor thickness is reliable to diagnose bladder outlet obstruction, with a high clinical promotional and diagnosis value.

Objective To investigate the relationship between bronchoalveolar lavage fluid (BALF) levels of interleukin (IL)-6, IL-8 and child bacterial pneumonia. Methods BALF levels of IL-6, IL-8 were detected by enzyme linked immunosorbent assay (ELISA) in 26 patients with bacterial pneumonia and 14 controls. Neutrophils and alveolar macrophages (AMs) of BALF were examined. Results BALF levels of IL-6, IL-8, total cell count and neutrophils of child bacterial pneumonia before treatment were significantly higher than those of pneumonia after treatment and controls (P<0.01). BALF levels of IL-6, IL-8 were significantly higher in Gram-negative infection than those in Gram-positive infection (P<0.01). BALF level of IL-6 showed positive correlation with AMs in pneumonia (r=0.7615, P<0.01). BALF level of IL-8 was correlated positively with neutrophils and AMs respectively in pneumonia (r=0.8956, r=0.6018, P<0.01). Conclusions IL-6 and IL-8 play the roles in the development of airway inflammation in child bacterial pneumonia. Detection of BALF levels of IL-6 and IL-8 is valuable to predict the state of child bacterial pneumonia.

Objective To evaluate endoscopic ultrasonography (EUS) for TN restaging and predicting response to advanced gastric cancer after neoadjuvant chemotherapy. Methods A total of 22 patients,15 males and 7 females, mean age 64 (36-80 years ), with advanced gastric cancer were recruited to the study from June 2007 to December 2009 with written informed consents. All patients underwent 3 cycles of neoadjuvant chemotherapy ( Folfox 6 ), and subsequent surgery ( R0 resction) in 3-4 weeks after chemotherapy. EUS was performed 1-2 weeks before and 1-2 weeks after chemotherapy. EUS TN staging was compared with pathological findings. The correlation of peri-chemotherapy EUS TN staging with postoperative pathological response was evaluated. Results After chemotherapy, the overall accuracy of EUS T staging was 63.6% (14/22), with overstaging (36. 4%, 8/22) more frequent than understaging (0). The overall accuracy of N staging was 54. 5% (12/22) with 4 ( 18. 2%, 4/22) overstaging and 6 ( 27. 3%, 6/22 ) understaging. EUS revealed T and/or N downstaging ( concyrrence of T and N downstaging was accounted once) after chemotherapy in 10 patients, with 9 T downstaging (4 from T3 to T2, 5 from T4 to T3) and 4 N downstaging (4 from N1 to N0). TN downstaging was correlated with pathological response, with 7 patients achieving pathological response 2 and 1 patient 3. Conclusion T and N restaging by EUS after neoadjuvant chemotherapy in patients with locally advanced gastric cancer is not accurate enough. However, T and/or N downstaging confirmed by EUS is well correlated with a better degree of pathological response to chemotherapy.

Objective To evaluate the efficacy and safety of intradetrusor injection of botulinum toxin type A in the treatment of ketamine-related cystitis.Methods A retrospective analysis of clinical data of 36 ketamine-related cystitis patients with intradetrusor injection of botulinum toxin type A treatment in our hospital during August 2010 to December 2015 was conducted, including 31 males and 5 females with a mean age of 25.5 years.All patients had failed to conventional treatment options including cessation of ketamine, antibiotics, M-blockers.At the time of the first injection, patients were injected with 200 U botulinum toxin type A diluted in 15 ml of 0.9％ saline into the detrusor muscle at 30 sites, sparing the trigone, under cystoscopic guidance.3-d voiding diary, interstitial cystitis symptom index (ICSI),interstitial cystitis problem index (ICPI), pelvic pain and urinary frequency/urgency symptom score (PUF) were recorded to evaluate the efficacy.The treatment-related complications were recorded.When the efficacy of botulinum toxin type A decreased and the patient's symptoms returned to baseline before treatment, the patient received repeated injections of botulinum toxin type A with the same dose and method as the first injection.Results Thirty-six patients with ketamine-related cystitis were treated with intradetrusor injection of botulinum toxin type A.Sixteen patients received two injection treatments and two patients received three injection treatments.During the follow-up, 3-d urinary diaries, ICSI, ICPI, and PUF showed a significant improvement in outcome at 4 weeks after the first injection.The efficacy of the second and third injection treatment was also remarkable.Three patients developed urinary tract infection after the first injection, and two patients developed urinary tract infection after the second injection.Mild hematuria occurred in 15 patients after the first injection, and mild hematuria occurred in 7 patients after the second injection, which was improved in 1 to 2 days.All patients did not appear acute urinary retention and other adverse drug reactions.Conclusions Intradetrusor injection of botulinum toxin type A could be a safe and effective method for the treatment of ketamine-related cystitis.Repeated injection therapy is still safe and effective.

Secondary immune response is an important endogenous mechanism of neurological injury after ischemic stroke.Spleen and interferon-γγplay an important role in it.Monitoring the spleen size and the level of interferon-γγhave an important reference significance for the severity of stroke and outcome assessment.

OBJECTIVETo evaluate the repairing methods of bulky tissue defect of forearm with flaps.

METHODSTwenty-one burned patients with wounds in the forearm were enrolled in this study. The injury causes were high-voltage electricity, hot press or crush injury. After local debridement, the forearm defects were repaired with pedicled complex flaps, latissimus dorsi musculocutaneous island flaps or large thoraco-abdominal flaps immediately.

RESULTSAll the flaps survived very well with satisfactory results except for 1 patient in whom local ischemic necrosis and sub-flap infection at the distal end of the flap occurred.

CONCLUSIONEarly debridement followed by skin flaps with pedicles or musculocutaneous flaps transfer could be simple, safe and reliable treatment strategies in the management of bulky tissue defects of the forearm due to burn, electric injury, or other devastating injuries.

Objective:To summarize and analyze the clinical data of Chinese patients with colony-stimulating factor 1 receptor (CSF1R)-related leukoencephalopathy, and clarify the phenotypic and genetic characteristics of Chinese patients.Methods:Medical history of patients with CSF1R-related leukoencephalopathy diagnosed from April 1, 2018 to January 31, 2021 in the department of neurology of 22 hospitals in China was collected, and scores of Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment Scale (MoCA), magnetic resonance severity scale were evaluated. Group comparison was performed between male and female patients.Results:A total of 62 patients were included, and the male-female ratio was 1∶1.95. The age of onset was (40.35±8.42) years. Cognitive impairment (82.3%, 51/62) and motor symptoms (77.4%,48/62) were the most common symptoms. The MMSE and MoCA scores were 18.79±7.16 and 13.96±7.23, respectively, and the scores of two scales in male patients (22.06±5.31 and 18.08±5.60) were significantly higher than those in females (15.53±7.41 , t=2.954, P=0.006; 10.15±6.26, t=3.328 , P=0.003). The most common radiographic feature was bilateral asymmetric white matter changes (100.0%), and the magnetic resonance imaging severity scale score was 27.42±11.40, while the white matter lesion score of females (22.94±8.39) was significantly higher than that of males (17.62±8.74 , t=-2.221, P<0.05). A total of 36 CSF1R gene mutations were found in this study, among which c.2381T>C/p.I794T was the hotspot mutation that carried by 17.9% (10/56) of the probands. Conclusions:The core phenotypic characteristics of CSF1R-related leukoencephalopathy in China are progressive motor and cognitive impairment, with bilateral asymmetrical white matter changes. In addition, there exist gender differences clinically, with severer cognitive impairment and imaging changes in female patients. Thirty-six CSF1R gene mutations were found in this study, and c.2381T>C/p. I794T was the hotspot mutation.
