Objective To analysis the correlation of obstructive sleep apnea-hypopnea syndrome (OSAHS) and perihematoma edema of hypertensive cerebral hemorrhage.Methods One hundred and forty-four patients with hypertensive cerebral hemorrhage were collected and 78 of these patients were suffered from OSAHS.The patients were divided into two groups,control and OSAHS group,according to whether were accompanied by OSAHS or not.Both of the groups received the routine treatments including dehydration,reducing blood press,protecting the cerebral cells and so on.Cerebral CT scan was taken on admission.Night polymonography (PSG) was done within 24 hours of admission.Twenty-four hours and 4 days after admission,cerebral CT scan was taken again.The volumes of cephalophyma and perihematoma edema were calculated according to the results of CT scan.The changes of cephalophyma and perihematoma edema were dynamic observed.Results No difference in patients' age,sex,body mass index,serum glucose,blood lipid and so on,was observed between the two groups.The relative edema index became significantly different until 4 days after admission (0.40 ± 0.45,0.96 ± 1.35 in control and OSAHS group respectively,t =4.149,P =0.000).Similarly,the alternation edema index of OSAHS was obviously higher than that of control group only in 4 days after admission.While the analysis of the correlation between different degree OSAHS groups and edema indexes showed that at 24 hours after admission the edema volumes for different degree OSAHS groups were consistent (1.05 ± 0.65,0.84 ± 0.48,1.20 ± 0.54,1.10 ±0.40 in control,slight,moderate and severe groups respectively,F =1.061,P =0.374).At 24 hours and 4 days after admission,the edema volumes were positively correlated with the degree of OSAHS.Alternation edema index was significantly correlated with apnea hypopnea index according to the result of Pearson' s correlation analysis (r =0.652,P =0.000).Conclusion OSAHS complication can promote the progression of perihematoma edema of hypertensive cerebral hemorrhage,and the degree of edema aggravation is positive correlated to the degree of OSAHS.

OBJECTIVE: To analyze the complication, survival and life quality, and to explore the efficacy and prognosis of skull base chordoma treated by open surgery and gamma knife surgery (GKS). METHODS: Thirty-eight patients with skull base chordomas who underwent an open surgery and another 19 patients who underwent GKS between January 2002 and January 2010 were followed up. The Karnofsky performance scale (KPS) at admission,discharge and follow-up, and recurrent rates were calculated through SPSS life-table, and survival rate curve was used to evaluate the efficacy and prognosis. RESULTS: Forty patients were followed up, and the survival rate of 1, 3 and 5 years was 92.6%, 74.3% and 60% in 27 patients with open surgery, and 100%, 83.3% and 62.5% in 13 patients with GKS respectively. There was no significant difference between the 2 groups (χ(2)=0.867, P=0.353). There was no significant difference in the KPS score between the 2 groups (P=0.138). CONCLUSION Despite the poor prognosis of skull base chordoma, GKS can effectively improve the survival rate and present life quality of patients with skull base chordoma.

OBJECTIVE: To evaluate the curative effects and complications when using microvascular decompression (MVD) or gamma knife surgery (GKS) to treat trigeminal neuralgia (TN). And to investigate the prognosis for TN after these treatments. METHODS: Sixty-one TN patients treated using MVD and eighty-six TN patients treated using GKS were enrolled by means of telephone, letter or out-patient recheck; the patients had originally presented from December 1996 to June 2010. A chi-square test was applied to follow-up data on pain relief after 1 month, 6 months and 12 months, and at the final follow-up. RESULTS: One hundred and two patients were followed for 3-151 months. Cumulative pain relief rates at 1, 6, 12 months and at end times were 90.48%, 95.24%, 92.86%, and 95.24%, respectively, for forty-two MVD-treated patients, and 23.33%, 83.33%, 86.67% and 90% for sixty GKS-treated patients, respectively. The effects of two methods for treatment of TN was not statistically different (χ(2) = 2.053, P=0.152). Pain relief rates in the short-term (first month) demonstrated statistically significant differences (P<0.01), but pain relief rates in the long-term showed no significant differences (P>0.05). CONCLUSION Immediate pain relief with MVD treatment is higher than with GKS, but in the long term both treatments were comparable.

Objective To investigate the antimicrobial resistance and resistance profiles of Salmonella isolates,from the pork production chain in several districts of Sichuan province and to determine the correlation between serotype and the pulse field gel electrophoresis(PFGE)patterns. Methods From 2010 to 2011,a total of 112 Salmonella isolates from pork production chain were examined for their antimicrobial susceptibility,using the micro-dilution method against 10 antimicrobial agents. Results were assessed by the standard by the Clinical and Laboratory Standards Institute (CLSI,2010). In addition,PFGE patterns were investigated among the Salmonella strains from different sources,under different serovars and antimicrobial profiles. Results For Salmonella isolated from the pork production chain,resistance to tetracycline(89.29%)was frequently observed. Many isolates were resistant to spectinomycin(36.61%),trimethoprim/sulfamethoxazole(35.71%), nalidixic acid(33.93%)and ampicillin(24.11%),but all of the isolates were susceptible to ceftiofur. 33.93% of the isolates were multi-drug resistant. Salmonella isolates from the pork production chain had 19 antibiotic resistance profiles. Totally,34 PFGE patterns were detected among 74 Salmonella isolates from the pork production chain,with the PFGE patterns of the 74 Salmonella isolates sharing 40%to 100%similarities. Conclusion The antimicrobial resistances of the Salmonella isolates were commonly detected from the pork production chain in Sichuan province suggesting that Salmonella might horizontally spread from food animals to retail meat products.

Objective To observe the changes ofmacular structure and choroidal capillary blood flow density in patients with acute central serous chorioretinopathy (CSC).Methods Prospective cross-sectional study.A total of 24 eyes of 24 patients with monocular acute CSC (case group) diagnosed by clinical examination from Shanxi Eye Hospital during January and March 2018 were included in the study.The eyes (24 eyes) and contralateral eyes (24 eyes) of the patients in the case group were set to CSC group and contralateral eye group,respectively.Twenty-one eyes of 21 healthy volunteers with age and gender matching were selected as normal control group.The macular structure of the eyes were observed by OCT and OCT angiography (OCTA),and the blood vessel density of choroidal capillary layer in the circular area of the macular area with a radius of 1 mm was measured.The paired t-test was used to compare the differences in blood flow density in the choroidal capillaries between the three groups.Results The results of OCT showed that the serous neuroepithelial detachment in the macular area was observed in all eyes of the CSC group,with or without RPE detachment being 20 or 4 eyes,respectively.Of the 24 eyes in the contralateral eye group,13 eyes (54.2％) had thick choroidal RPE lesions (PPE).There was no abnormality in the retina and choroidal structure in the macular area of the normal control group.The results of OCTA showed that the blood flow density of choroidal capillaries in the CSC group,the contralateral eye group and the normal control group were 1.759 ± 0.132,1.924± 0.463,and 1.940± 0.033,respectively.Compared with the eyes of the contralateral eye group and the normal control group,the blood flow density of choroidal capillaries in the CSC group was significantly lower (t=6.611,6.474;P=0.000,0.000).There was no significant difference in the blood flow density of choroidal capillary layer between the contralateral eye group and the normal control group (t=1.328,P ＞ 0.05).In the contralateral eye group,there was no significant difference in the blood flow density of choroidal capillary layer between PPE eyes and no RPE eyes (t=0.806,P＞0.05).Conclusions There is 54.2％ of the contralateral eyes in the monocular acute CSC patients with PPE.The choroidal capillary layer blood flow density is lower than that of the contralateral and normal eyes.

Objective    To compare the clinical effects of segmentectomy and lobectomy for ≤2 cm lung adenocarcinoma with micropapillary and solid subtype negative by intraoperative frozen sections. Methods    The patients with adenocarcinoma who received segmentectomy or lobectomy in multicenter from June 2020 to March 2021 were included. They were divided into two groups according to a random number table, including a segmentectomy group (n=119, 44 males and 75 females with an average age of 56.6±8.9 years) and a lobectomy group (n=115, 43 males and 72 females with an average of 56.2±9.5 years). The clinical data of the patients were analyzed. Results    There was no significant difference in the baseline data between the two groups (P>0.05). No perioperative death was found. There was no statistical difference in the operation time (111.2±30.0 min vs. 107.3±34.3 min), blood loss (54.2±83.5 mL vs. 40.0±16.4 mL), drainage duration (2.8±0.6 d vs. 2.6±0.6 d), hospital stay time (3.9±2.3 d vs. 3.7±1.1 d) or pathology staging (P>0.05) between the two groups. The postoperative pulmonary function analysis revealed that the mean decreased values of forced vital capacity and forced expiratory volume in one second percent predicted in the segmentectomy group were significantly better than those in the lobectomy group (0.2±0.3 L vs. 0.4±0.3 L, P=0.005; 0.3%±8.1% vs. 2.9%±7.4%, P=0.041). Conclusion    Segmentectomy is effective in protecting lungs function, which is expected to improve life quality of patients.
