Objective To investigate the clinical features and the imaging examination changes of bacterial meningitis in children of different age groups,and to offer theoretical basis for the clinic diagnosis of bacterial meningi-tis. Methods The sick children with bacterial meningitis treated in Guangzhou Women and Children′s Medical Center from January 2011 to June 2013,were recruited and divided into three groups according to the age,including newborns group,infants group and more than 1 year group. Eighty-nine cases with purulent meningitis were recruited,included 58 males and 31 females. Among them,there were 34 cases in the newborns group,41 cases in the infants group and 14 ca-ses in the more than 1-year group. The information on the clinical features,laboratory examination and the imaging ex-amination were summarized and analyzed,and were compared among the 3 groups. Results (1)Among them,54 cases with high fever,44 cases with respiratory symptoms,12 cases with alimentary tract symptoms. (2)The major neurologi-cal features included convulsions(44 cases,49. 4%),fatigue(36 cases,40. 4%),vomiting(21 cases,23. 6%),cervical rigidity(9 cases,10. 1%),fontanel full(7 cases,7. 9%),headache(6 cases,6. 7%),limb paralysis(5 cases,5. 6%). The percentage of high fever,vomiting,headache,cervical rigidity in the more than 1 year group were significantly more than those of the newborns group and the infants group(χ2=10. 093,12. 063,34. 466,7. 177,all P<0. 05). (3)Among them,whitebloodcell(WBC)accountswerefrom2.20to60.60×109/L,themeanwas(16.49±10.37)×109/L.Hy-persensitive C-reaction protein concentration in blood was 4. 00 to 376. 53 g/L,the mean was (131. 07±86. 91) g/L. In cerebrospinal fluid(CSF),WBC accounts were from 1 to 21 800×106/L,the mean was (910. 05±274. 07)×106/L, the glucose concentration from 0. 00 to 4. 50 mmol/L,the mean (1. 72±1. 03)mmol/L,the protein concentration from 0. 42 to 4. 89 g/L,the mean was(1. 64±1. 03)g/L. In 40 cases with atypical CSF change, 23 cases with CSF glucose ratio(CSF glucose/blood glucose) less than or equal to 0. 4, and 15 cases with blood cultures positive. (4)The image examination showed magnetic resonance imaging( MRI) abnormalities in 51/75 cases,computerized tomography( CT) scan abnormalities in 15/30 cases. The percentage of convulsions,the brain MRI abnormalities and the MRI display rate of bacterial meningitis in the infants group were significantly more than those of the newborns group and the more than 1 year group(χ2=11. 768,9. 047,7. 674,all P<0. 05). The display rate of meningitis and subdural hydroma by the brain MRI were significantly more than those of the head CT scan(χ2=7. 430,5. 291,all P<0. 05). Conclusions Be-cause of the atypical clinical features of bacterial meningitis in newborn and infant, lumber puncture should be per-formed in all doubtful cases who had a fever and/or seizure. CSF glucose less than or equal to 0. 4 of simultaneously ob-tained blood glucose value,the enhanced MRI sequence or blood cultures were useful for the likelihood of meningitis,if CSF chemistries and cytology vary atypically. The MRI sequence can significantly mostly improve the display rate of bacterial meningitis than the enhance CT.

Objective To investigate the effects of PM2.5 exposure on the quality of IVF eggs and the quality of embryos. Methods 40 healthy female Kunming mice and 10 male mice were used in this study. 40 female mice were randomly divided into 4 groups:low dose of PM2.5 group (1.5 mg/kg),middle dose of PM2.5 group (7.5 mg/kg),high dose of PM2.5 group (15 mg/kg) and the control group (to give the same volume of saline),with 10 mice in each group. PM2.5 was administered via tracheal instillation. The number of oocytes ,fertilization rate ,abnormal fertilization rate ,2PN cleavage rate ,2PN blastocyst rate and blastocyst formation rate were determined ,as well as levels of TNF-α and IFN-γ. Results The number of oocytes , fertilization rate and cleavage rate of 2PN were significantly higher in PM2.5 high dose of PM2.5 group than those in PM2.5 group. The rate of high quality embryos and blastocyviast formation were decreased ,but abnormal fertilization rate were decreased (P < 0.05). The expressions of TNF-α and IFN-γ in the high-dose of PM2.5 group were significantly higher than those in the middle-dose of PM2.5 group and in the low-dose of PM2.5 group(P < 0.05),while the expressions of TNF-α and IFN-γ in the middle dose group was significantly higher than those in the low dose group(P<0.05). Conclusions PM2.5 exposure can decrease the number of oocytes , fertilization rate ,2PN cleavage rate ,2PN blastocyst rate and blastocyst formation rate of in vitro fertilization in mice.

Objective:
To investigate the operating key steps and the initial experience of IUPU (Institute of Urology, Peking University) modified extraperitoneal laparoscopic VIP (Vattikuti institute prostatectomy) technique and the initial follow-up outcomes.
Methods:
46 patients of prostate cancer underwent the modified extraperitoneal laparoscopic VIP and were reviewed from November 2017 to September 2018. Patients aged 54 to 77 years, with mean age of 65.5 years old. Their preoperative PSA was 0.15 to 69.76 ng/ml with an average of 13.4 ng/ml. All patients were diagnosed by prostate biopsy and Gleason score was 6 to 10 with an average of 7.5. MRI was used to assess their clinical stage before operation. All the modified laparoscopic VIP were done through the extraperitoneal approach by a single surgeon and the follow-up by telephone for the PSA level and continence recovery (urine pad test). The major differences between modified laparoscopic VIP and the routine steps of radical prostatectomy are as follows: use of extraperitoneal approach and traditional laparoscopic operation; after the setup of the extraperitoneal cavity, the bladder neck is separated, isolated and cut down first; the management of DVC: Cut down the super-facial and deep layers of DVC just along the capsule of the prostate apex and it’s unnecessary to suture it. Perioperative data of these patients were collected retrospectively, including operation time, intraoperative blood loss, length of hospital stay, postoperative pathology, and continence outcome after surgery.
Result:
All 46 patients underwent the IUPU modified extraperitoneal laparoscopic VIP successfully without converting to open surgery. The operation time was 69-143 min with an average of 95.7 min and the estimated blood loss was 20-200 ml with an average of 81.5 ml. It was 3-17 days for the average time to remove the retropubic drainage tube postoperatively, with an average of 4.3 days. The postoperative hospital stay was 3-17 days with an average of 5.3 days. The Foley catheter was removed 14 days postoperatively. Five patients suffered from urine leakage and were managed successfully with conservative treatment. For the postoperative pathological stage, 1 patient was pT2a, 12 patients were pT2c, 12 patients were pT3a and 21 patients were pT3b. The postoperative Gleason score was 6-9 with an average of 7.7. The postoperative follow-up time was 1-11 months with an average of 6.3 months. The PSA was 0.001-0.966 ng/ml with an average of 0.181 ng/ml 1 month postoperatively and the continence rate was 54%(25/46) and 89%(34/38) 1 month and 3 months after operation respectively.
Conclusions
The IUPU modified extraperitoneal laparoscopic VIP might be a safe and feasible for the radical prostatectomy. It’s simplified for the operative steps, unnecessary to isolate and suture DVC and doesn’t increase the blood loss. It’s almost left intact for the surrounding tissues of the prostate apex and satisfactory for the early urinary continence. The oncological outcomes are needed to followup further.

OBJECTIVETo compare the efficacy of laparoscopic versus open tension-free mesh repair using biologic mesh for inguinal strangulated hernia.
METHODSClinical data of 27 patients with inguinal strangulated hernia in the Shanxi Provincial People's Hospital between January 2012 and April 2014 were analyzed retrospectively. All the patients underwent one-stage tension-free repair using biological mesh, including laparoscopic(n=13) and open procedures(n=14).
RESULTSAs compared with the open group, the laparoscopic group had shorter operative time [(90.8±11.6) min vs. (130.8±32.5) min, P<0.01], lower rates of hematoma/seroma and wound infection[(7.7% vs. 42.9%) and (0 vs. 28.6%) respectively, both P<0.05], faster recovery of bowel function [(2.5±0.3) d vs. (3.8±1.4) d, P<0.01], and shorter hospital stay [(6.3±1.8) d vs. (9.8±3.2) d, P<0.01]. The mean follow-up was 5.7 months (ranged from 2 to 12 months), and no recurrence or serious complications occurred.
CONCLUSIONLaparoscopic tension-free hernia repair using biological mesh for inguinal strangulated hernia has significant advantage versus open operation.
