Objective To analyze the surveillance data from 2003 to 2007 for Hubei province,investigate the epidemic characteristics of human rabies in these years,so as to provide scientific basis for its control and prevention.Methods Rabies data collected from the National Disease Surveillance Reporting System from 2003 to 2007 in Hubei province and 134 Rabies cases investigated in 2007 were analyzed in detail.Results The results showed that the trend of the number of rabies reported cases in Hubei province was obviously increased from 2003 to 2007.The involved counties and districts of the epidemic situation were widely expanded accordingly.Each month had Rabies case,but a lot of cases were dominated in August to November for every year.Most of the cases were farmers and students.The sex ratio of male to female was 2.38∶1.The age of the cases were mainly ranged from 5 to 15 and from 40 to 70 years old.Investigation of 134 cases indicated that the median of the incubative period was 66 days;94.78% of cases were injured by the dog;only 15.67% of injured cases were treated by the medical institution;the vaccinate ratio was 14.93%;the proportion of patients who received wound treatment,vaccinate and passive immunization were 5.80% of all the grade-Ⅲ-exposed patients.Conclusions The epidemic situation of Rabies was serious from 2003 to 2007 for Hubei province.The main reasons of the increase of rabies cases in Hubei province are absence of the effective management of the dog,the lack knowledge of rabies prevention,low rate of vaccine and passive immunization after exposure,and the lack of the standardized management for some of the low level medical institutions.

Objective:To explore the clinical features and risk factors of systemic inflammatory responses syndrome (SIRS) after flexible ureteroscopic lithotripsy (FURL) with upper urinary tract stones.Methods:A retrospective of 157 patients with upper urinary calculi treated by FURL who were admitted to Suzhou First People′s Hospital from January 2018 to October 2020 were selected to analyze the treatment results and complications of the patients. Patients were divided into SIRS group ( n=31) and non-SIRS group ( n=126) according to whether they were complicated by SIRS. The clinical data between the two groups were analyzed by a single factor, and the factors with statistical significance were included in the LASSO-Logistic regression analysis. Visualize the model through the Nomogram, and verify and evaluate the discrimination and accuracy of the model. Results:The results of univariate analysis showed that gender( P=0.010), average stone size ( P<0.05), preoperative urine white blood cell count ( P<0.05), operation time ( P<0.05) and postoperative stone bacterial culture ( P<0.05) were different between the two groups and the differences were statistically significant. The LASSO-Logistic regression analysis results show that the above factors were all independent risk factors for patients with SIRS. The Nomogram complicated SIRS risk prediction model constructed based on the above risk factors has good discrimination and high consistency with actual observations. Conclusion:Females, large stones, high preoperative white blood cell counts, longer operation time, and positive bacterial culture of postoperative stones are independent risk factors for SIRS after FURL in patients with upper urinary calculi.

Objective To investigate the dosimetric difference of organ at risk (OAR) for planning and actual estimated during intensity-modulated radiotherapy (IMRT) for patients with nasopharyngeal carcinoma.Methods Thirteen patients were enrolled to accept full course of IMRT.CT scans were acquired in the 10th,20th,and 30th fractions during radiotherapy,respectively.OAR,including brain stem,spinal cord,parotid gland and submandibular gland,were delineated on repeated CT scans.The volume change of OAR were investigated.After that,the plans were copied to the new CT image to calculate the escalated average dose of OAR during radiotherapy (Actual estimated receiving dose minus planning dose).Results The change trend of volume was decreasing gradually for parotid gland and submandibular gland during the 10th,20th,and 30th times radiotherapy (all P =0.000).The maximum dose (Dmax) of brain stem and spinal cord and the 50％ volume receiving dose (D50) of parotid gland increased significantly in the 10th,20th,and 30th times during radiotherapy,respectively.The escalated average dose were 3.76 and 3.68 Gy for Dmax of brain stem and spinal cord (P =0.000,0.000),5.11 and 3.54 Gy for D50 of left and right parotid (P =0.001,0.023),and 0.49 and 0.75 Gy for D50 of left and right submandibular gland (P =0.220,0.230),respectively.Conclusions The volume of parotid gland and submandibular gland significantly decreased after radiotherapy The actual receiving dose of brain stem,spinal cord,and parotid gland increased significantly during radiotherapy.However,there was no significant change for the actual receiving dose of submandibular gland.

Objective To compare the dosimetry between inversely optimised intensity-modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy using the field-in-field technique (FIF) for whole-breast radiotherapy with a boost to the tumor bed after breast-conserving surgery.Methods IMRT and FIF treatment plans were respectively performed and optimised for 9 patients with early stage leftbreast cancer after breast-concerving surgery.The prescribed dose of breast was 50.4 Gy in 28 fractions,1.8 Gy per fraction and that of tumor bed was 61.6 Gy in 28 fractions,2.2 Gy per fraction.The conformity index,the dose and volume for OAR( organs at risks),time of planning and treatment for the two plans were compared.Results The conformity index(CI) for IMRT was improved compared with the FIF in breast [(1.82±0.16) vs.(2.21±0.15)] and tumor bed [(1.19±0.04) vs.(1.59±0.11),t=2.08,3.97,P ＜ 0.05 ].There was no difference for V20 of ipsilateral lung and V30 of heart between two plans.The Dmax and Dmean of the contralateral lung of FIF were (5.41 ±2.76) and (0.51 ±0.10) Gy,lower than those of IMRT [ (25.72 ± 2.61 ) and (7.46 ± 0.39) Gy,t =-22.44,- 21.14,P ＜ 0.05 ].The Dmax and Dmean of the contralateral breast of FIF were (8.50 ± 5.61 ) and (0.47 ± 0.11 ) Gy,lower than those of IMRT [(27.73±4.30) and (6.38±0.48) Gy,t=-5.66,-14.83,P＜0.05].ForFIF,theV5of the contralateral lung and breast were (0.09 ± 0.09) ％ and (0.45 ± 0.45 ) ％,respectively,lower than those of IMRT,which were (84.66 ±3.06) ％ and (60.79 ±4.94)％ (t =-28.19,- 12.80,P＜0.05).The time of optimised plan was (61.57 ± 0.89) min for FIF and(241.28 ± 1.06) min for IMRT (t=-32.35,P＜0.05),and that of treatment were (16.14±1.42) min for FIF and (29.85 ±0.59) min for IMRT (t =- 8.82,P ＜ 0.05).Conclusions For patients with early stage breast cancer after breast-concerving surgery,IMRT could improve the conformity index of target but increase the dose of eontralateral lung and breast.However,FIF has advantage on the time of optimising plan and treatment.

Objective To assess the value of emergency interventional embolization in treating traumatic spleen rupture. Methods A total of 74 patients with traumatic spleen rupture, who were encountered at authors’ hospital during the period from July 2007 to July 2013, were enrolled in this study. The clinical data were retrospectively analyzed. The patients were divided into embolization group (n = 38) and surgery group (n = 36). Interventional splenic artery embolization was carried out in the patients of the embolization group, and surgical repair was employed in the patients of the surgery group. The operation time, the amount of blood loss during the procedure, the hospitalization days, the preservation rate of the spleen and the occurrence of procedure- related adverse events were recorded, and the results were compared between the two groups. Results No significant difference in the operation time existed between the two groups (P = 0.061). The amount of blood loss during the procedure, the hospitalization days and the occurrence of procedure- related adverse events in the embolization group were significantly lower than those in the surgery group (P < 0.05), while the preservation rate of the spleen of the embolization group was significantly higher than that of the surgery group (P = 0.026). Conclusion Emergency interventional embolization is a safe procedure for the treatment of traumatic spleen rupture, this technique can improve the preservation rate of the spleen when compared with traditional surgical repair treatment.

Objective To investigate the difference in normal tissue complication probability (NTCP) of lower cranial nerves (LCNs) between target volumes recommended by Radiation Therapy Oncology Group (RTOG) and China in intensity-modulated radiotherapy (IMRT) for T1-2 nasopharyngeal carcinoma (NPC),and to provide the evidence of dose-volume effect for the protection of LCNs in IMRT for NPC.Methods A total of 20 patients with T1-2 NPC who were treated from 2013 to 2015 were enrolled,and LCNs were delineated on CT images.Target volume delineation and treatment plan designing were performed according to the method recommended by RTOG0225 (RTOG target volume delineation method) or the Chinese Working Committee for Clinical Staging of NPC in 2010 (Chinese target volume delineation method),and the differences in the dose to LCNs and NTCP were calculated.Results In the RTOG and Chinese methods for target volume delineation,Dmax to the left and right LCNs was 7 450±273 cGy/7294±309 cGy and 7 361± 160 cGy/7 190±395 cGy,respectively (P=0.018 and 0.042),Dmean was 6735±285 cGy/6 660±333 cGy and 6 446±429 cGy/6 299±467 cGy,respectively (both P=0.000),and the NTCP was 60％±10％/57％±13％ and 51％±15％/45％±17％,respectively (both P=0.000).Conclusions It is feasible to precisely delineate target volume with the LCNs as a routine OAR and predict NTCP in IMRT for T1-2 NPC.The NTCP of the LCNs is closely associated with target volume dose and irradiated volume.The dose to the LCNs and NTCP determined by the Chinese target volume delineation method are significantly lower than those determined by the RTOG method.
