Objective To analyze the clinical manifestations and the features of brain MRI and cerebrospinal fluid (CSF) findings in adult Chinese patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis.Methods We reviewed the clinical manifestations,brain MRI and CSF examinations of 29 patients who were diagnosed as anti-NMDAR encephalitis.Results The major clinical features of anti-NMDAR encephalitis patients included psychiatric symptoms (86％,25/29),seizures (83％,24/29),decreased consciousness (55％,16/29),involuntary movements (55％,16/29),central hypoventilation (34％,10/29),and hypersalivation (17％,5/29).Some patients also experienced autonomic instability,hemiplegia and aphasia.Underlying ovarian teratoma was identified in 14％ of affected patients(4/29).Brain MRI was found abnormal in up to 62％ patients (18/29),located in the temporal lobes,hippocampus,thalamus,brain stem,cingulate gyrus,frontal and parietal cortex,corpus callosum,internal capsule,basal ganglia and periventricular area.CSF findings were abnormal in 83％ of patients with anti-NMDAR encephalitis.Oligoclonal banding in CSF was positive in 95％ patients (19/20).The recurrence rate during 3 years was 31％ (9/29).Conclusions Anti-NMDAR encephalitis is a treatable disease,yet with high recurrence rate.Its predominant clinical features are psychiatric symptoms and seizures,while involuntary movements,central hypoventilation and hypersalivation are its characteristic manifestations.Lesions in MRI are widespread,not only restricted to limbic lobe.

SUMMARY Intravesical bacillus Calmette-Guérin ( BCG) was a common treatment for non-muscle inva-sive urothelial carcinoma of the bladder. The complication of prostatic abscess was rare. We reported a case of tuberculous prostatic abscess after BCG therapy. A 65-year-old man was diagnosed as bladder cancer and accepted transurethral resection of bladder tumor ( TURBT) treatment. He received a 6-week induction course without any infection complication. Following the second BCG maintenance instillation, he complained of fever and dysuria. Transrectal ultrasound ( TRUS) demonstrated a well-defined complex mass in the right lobe of his prostate. The diagnosis of tuberculous prostatic abscess was considered after excluding other bacterial infection. The patient was treated with an anti-tuberculous regimen of isoniazid, rifampicin, and ethambutol. The symptoms were relieved after 4 weeks of anti-tuberculous therapy. Be-cause of the good response to the medicine, no further aspiration or drainage of prostatic abscess was car-ried out. The anti-tuberculous therapy had to be stopped for serious drug induced liver injury after 6 weeks of anti-tuberculous therapy. Eight weeks later of stopping anti-tuberculous therapy, the follow-up TRUS showed the disappearance of the prostatic abscess and the test of his liver function was normal. Considering the virulence of BCG is weaker than that of common tuberclebacillus, the shorter course of anti-tuberculous therapy maybe an alternative choice, and surgical drainage is not always necessary.

Objective: To explore the value of implanted intensity-modulated bmchytherapy for recurred cervical carcinoma. Metheds: A total of 25 cases of recurred cervical carcinoma were enrolled into the trial group which were treated with pelvic implanted aftedoading intensity-modulated brachytherapy. The other 25 patients with recurred cervical carcinoma treated with routine brachytherapy during the same pedod were en-rolled into the control group. Results: There were 20 cases with CR and 5 cases with PR in the trial group, and 10 cases with CR, 7 cases with PR, 4 cases with SD and 4 cases with PD in the control group, with a signifi-cant difference between the two groups (P<0.05). In the trial group, there were 5 cases with vaginal-rectal fis-tula and 1 case with grade 3 enteritis. In the control group, there were 3 cases with vaginal-rectal fistula. Con-dusion: Pelvic implanted intensity-modulated brachytherapy for recurred cervical carcinoma is satisfactory with better short-term efficacy than that of the routine brachytherapy and tolerable side effects.

Objective To summarize the experience of management of upper urinary tract calculi by Extracorporeal Shock Wave Lithotripsy (ESWL) in our department in order to improve the gravel success rate and decrease the incidence of complications.Methods 15 019 patients with upper urinary calculi from October 1988 to September 2011 treated by ESWL with X-ray localization were analyzed retrospectively.The maximum diameter of the stones ranged from 0.8 cm to 3.2 cm,with 1 3 794 cases with maximum stone diameter less than 2 cm (guoup A),and with 1225 cases with maximum stone diameter more than 2 cm (guoup B).All patients had normal or nearly normal renal function,and 56.0％ patients (8 410/15 019)had varying degrees of hydronephrosis.Results The effective rate of first ESWL was 84.5％ ( 12 691/15 019) and the effective rate of second ESWL was 12.0％ (1 802/15 019),and 313 cases need a third ESWL.The clearance rate in group A was 90.2％ ( 12 443/13 794 ),in group B was 50.9％ (623/1225),and the overall stone clearance rate within three months was 87.0％ ( 13 066/15 019).The majority of patients ( about 93％ ) had postoperative gross hematuria,which disappeared after drinking lots of water.46cases (0.3％) of patients had postoperative fever,which returned to normal after usage of antibiotics.There were no serious complications such as kidney hematoma,continuous high fever,continuous hematuria,ureteral stones jams.Conclusions ESWL.with X-ray localization had the advantage of low energy,minor injury,easy localization,uniform stone fragment,because of which it could reduce the complications such as continuity fever,ureter stone james,continuious hematuria.ESWL with X-ray localization could be preferred treatment for upper urinary calculi with diameters between 10 to 20 mm.

Objective: To investigate the position and the size of ureteral stone in patients before treated with ureteroscopic lithotripsy or percutaneous nephrolithotomy (PCNL), as well as the dilatation of ureter caused by stone, which may be helpful for better understanding of pathogenesis of ureteral stone and improvement of the diagnosis and treatment in clinic.Methods: A total of 129 cases with ureteral stone for endourologic lithotripsy in Peking University People''s Hospital from Aug.2016 to Mar.2017 were included for the retrospective review.The CT data of the ureteral stones and the ureteral dilatation were collected, including the position of stone, the transverse and longitudinal diameter of stone, and the transverse diameter of dilated upper ureter and ureteropelvic junction (UPJ).The distribution of ureteral stones and dilatation in different parts of ureter were compared and analyzed.Results: All of the 129 cases of ureteral stone, stones were located at UPJ in 9 cases (7.0%), proximal ureter in 75 (58.0%), ureter crossing external iliac vessel (UEIV) in 6 (4.7%), distal ureter in 26 (20.2%), and ure-terovesical junction (UVJ) in 13 (10.1%).The mean transverse diameter of proximal ureteral stones was greater than that of distal ureteral stones [(8.47±2.36) mm vs.(6.74±1.99) mm, P<0.001], as the same as the mean longitudinal diameter [(11.00±4.41) mm vs.(7.50±4.28) mm, P<0.001].In 114 cases of dilated ureter for stone, the UPJ had a greater transverse diameter compared with the upper ureter [(14.39±6.09) mm vs.(11.45±3.85) mm, P<0.001].Conclusion: The most common location of stone is the proximal ureter in patients for endourologic lithotripsy, as the location in UEIV is rare.Both transverse and longitudinal diameters of stone in proximal ureter are greater than those in distal ureter.For dilated ureter, it is more severe in UPJ than in upper ureter.Traditionally, it is accepted that the stones lodge at 3 sites of natural narrowing in ureter, which may be questioned.

Objective:To investigate the peripheral mechanism by studying the histological changes of masseter muscles using HE stains and substance P(SP) and protein gene product 9.5(PGP9.5) immunohistochemical stains.Methods: Fifteen male Sprague-Dawley were randomly assigned into occlusal interference group(n=12) and control group(n=3).In occlusal interference group,0.4 mm thick crowns were bonded to the rats'first molar of the maxillary.In the control group,rats were anesthetized and mouths were forced open for about 5 min but restorations were not applied.1,5,10,and 21 d after 0.4 mm occlusal alteration treatment,mechanical pain thresholds of bilateral masseter muscles were quantitatively measured by modified electronic anesthesiometer in control group and occlusal interference group.The rats were euthanized by transcardiac perfusion after deep anesthetization at different time points.The paraffin sections of masseter muscles were made and processed for HE,SP,and PGP9.5 immunohistochemical staining.Results: Decreased head withdrawal threshold to mechanical pressure was detected in masseter muscles on both sides following occlusal interference.Histological stains of masseter muscles presented intact following occlusal interference,and no inflammatory cells were observed in both sides.Intensely stained PGP9.5 was observed at 1 d in occlusal interference groups and maintained until the end of the experiment.SP expression was the most obviously increased at 5 d in both sides and gradually decreased to the level of control.Conclusion: Experimental occlusal interference-induced masticatory muscle pain is associated with peripheral sensitization of nociceptive neurons rather than muscle damage and inflammation.
