Objective To investigate the possible pathogenesis of the cognitive function in unilateral frontal bottom laceration by follow-up study in patients after one month of the onset. Methods MMSE, Loewenstein Occupational Therapy Cognitive Assessment (LOTCA), Montreal Cognitive Assessment (MoCA), Wisconsin Card Sorting Test (WCST) scales were used to evaluate neurocognitie function in 42 patients after one month of onset of unilateral frontal bottom laceration and 45 normal controls. The wave amplitude and the latency of the endogenous composition N2, P3 of P300 were measured at the cognitive potential instrument. Level of AChE was determined by ELISA and active AChE was analyzed by the ration analyses. Stepwise multivariate regression analyzed the correlation of the overall cognitive function and the lever and active of AChE. Results The cognitive test scores in patients were significantly worse than those in normal controls. The ability of recite sentences, fluency of words, reading, understanding language,cognitive transfering decreases in the left frontal bottom laceration patients (Group A, 23 cases), while the ability of attention, action, organization, graphics depicting, abstract epitoming, logical thinking were all seriously impaired in the patients with right frontal bottom laceration (Group B, 19 cases). The latency of the endogenous composition N2, P3 in patients ( Group A: (322. 4 ± 17.0), (410. 1 ± 19.9) ms; Group B:( 308.4 ± 15.6), (385.5 ± 17.4) ms) is more lengthen ( F = 4. 084, P = 0. 018; F = 3.467, P = 0. 038 )than the normal controls ( (268.6 ± 14. 7 ), ( 369. 2 ± 15. 4 ) ms) and the wave amplitude is lower ( F =2. 986 ,P =0. 047 ;F =3. 313 ,P =0. 041 ). The latency of N2 ,P3 in Group A of is more lengthen than Group B, while the wave amplitude is higher. The difference of the active of AChE in patients and control groups had no statistical significance, however, the level of AChE in two groups had statistical significance. The comparison of the active and the total AChE in patients has also not statistical significance. The correlation of the overall cognitive function has the linear regression with the parts of the brain and the level of AChE ( rY1.2 = 0. 584, P = 0. 039; rY2.1 = 0. 726, P = 0. 017 ). The standardized regression coefficients showed the level of AChE has the biggest influence to the overall cognitive function ( |Beta| =0. 3601, rY2.1 =0. 726).Conclusions AChE may be one of the important factors in the cognitive function after frontal bottom laceration. The specific damages of cognitive function in unilateral frontal bottom laceration patients closely relate with the lesion locations in the injured frontal bottom laceration.

Objective To investigate the risk factors of incisional wound infection and put forward prevention measures to control the incision infection in patients under craniectomy.Methods Seventy patients with infection and 70 without infection of incisional wound among 1756 patients undergoing craniectomy from January 2011 to December 2013 were chosen in our study;and their clinical data were retrospective analyzed;etiological examination was performed on the secreta of these patients;the high risk factors of incisional wound infection were analyzed using multivariable Logistic regression.Results As compared with those in the non-infection group,patients in the infection group had significantly older age,lower albumin and Glasgow coma scale (GCS) scores,higher blood glucose level and APACHE Ⅱ scores,and higher percentages of surgical access station,microscopy applications,duration of surgery＞4 h and blood transfusion (P＜0.05).Pathogenic bacteria was positive in 88.57％ patients (62/70),including 45.71％ gram negative bacilli,40.00 ％ gram positive coccus and 2.86％ fungus.Multivariate Logistic regression analysis further showed that albumin,blood glucose,microscopy applications,duration of surgery＞4 h,blood transfusion,APACHE Ⅱ scores and GCS scores were significantly associated with incision infection,being the independent risk factors for incision infection.Conclusions To aim directly at the high-risk factors of incision wound infection,such as albumin,blood glucose,microscopy applications,duration of surgery,blood transfusion,APACHE Ⅱ and GCS,we should develop reasonable and effective preventive measures to reduce the incidence of incision infection and improve patient prognosis.

Objective:Focusing on the medical protection of marine sports events at the 19th Asian Games in Hangzhou. This paper analyzes the effect of the development and implementation of the medical protection program to provide a referable summary of experience for the medical protection of future large-scale international maritime events.Method:This paper retrospectively analyzed the medical protection of Ningbo Xiangshan Yafan Center during the preparation stage of the Asian Games Sailing Competition, and during the period from September 21 to September 27, 2023 when the Asian Games Sailing Competition is held. Analyze the organizational structure and scheme of medical support.Results:During this Asian Games sailing competition, there were a total of 14 paramedics, 4 rescue helicopter crews, 2 ambulances and 1 rescue helicopter in and around the competition venues. In the city, the designated hospital has set up a total of 12 working groups, 15 protection outpatient clinics and a number of various types of clinic areas. There are 129 medical and nursing staff directly participating in the medical protection work of the Asian Games. A total of 44 specialized beds were reserved in the designated hospitals. There were also a number of volunteers and logistic staff who relied on the support work. The top three major disease types were trauma with 66 cases (29.2%), upper respiratory tract infection with 34 cases (15.04%) and skin allergy with 19 cases (8.51%). The top two population groups consulted were staff with 95 visits (44.19%) and technical officers with 89 visits (41.40%).Conclusions:During the sailing competitions of the Asian Games, the medical care was smooth and orderly. Trauma, upper respiratory tract infections and skin allergies are the most prominent diseases. The number of medical consultations for staff and technical officials of the Asian Games Sailing Competition accounted for more than 80% of the total number of consultations for all personnel. They should be given priority care.

OBJECTIVE: To analyze the prognosis of fetuses identified with de novo variants of unknown significance (VOUS) by chromosome microarray analysis (CMA). METHODS: A total of 6 826 fetuses who underwent prenatal CMA detection at the Prenatal Diagnosis Center of Drum Tower Hospital from July 2017 to December 2021 were selected as the study subjects. The results of prenatal diagnosis, and outcome of fetuses identified with VOUS of de novo origin were followed up. RESULTS: Among the 6 826 fetuses, 506 have carried VOUS, of which 237 were detected for the parent-of-origin and 24 were found to be de novo. Among the latters, 20 were followed up for 4 to 24 months. Four couples had opted elective abortion, 4 had developed clinical phenotypes after birth, and 12 were normal. CONCLUSION Fetuses with VOUS should be continuously follow-up, in particular those carrying de novo VOUS, in order to clarify their clinical significance.
