Objective To evaluate the clinical effect of laparoscopy in the modified nerve painesparing radical hysterectomy (NPSRH) of early stage cervical cancer.Methods From January 2014 to December 2015 in our hospital,38 patients with early cervical caucer were enrolled and randomly divided into NPSRH group and laparoscopic radical hysterectomy (LRH) group in the study.The surgery general situations of two groups were compared,and postoperative intestinal and bladder function of these patientswere also assessed.Results All of 38 patients were successfully completed the operation,without significant intraoperative or postoperative complications.There were no significant differences in the bleeding volume,pelvic lymph dissection number,cut length of main ligament and sacral ligament,cut length of anterior vaginal wall,and posterior vaginal wall between two groups (P ＞ 0.05).The mean operation time in NPSRH group was longer than in LRH group,but the duration of postoperative hospital stay was shorter than the latter (P ＜ 0.01).Compared to control group,the catheter retention time,residual urine volume,maximal micturition volume,and Qmax in the NPSRH group recovered better,and with lower rate of nocturia mnd dysuria (P ＜ 0.05).The exhaust time and anal defecation time in the NPSRH group were significantly shorter than the LRH group,and lower rate of constipation additionally (P ＜ 0.05).Conclusions The laparoscopy in the modified nerve paine-sparing radical hysterectomy is a safe and effective measurement for the treatment of early-stage cervical cancer patients.It can significantly reduce the duration of postoperative hospital stay,promote the functional recovery of bladder and rectum,and improve the patients'postoperative quality of life.

[ABSTRACT]OBJECTIVETo assess the sleep body position's effects on AHI and ODI during sleep in obstructive sleep apnea hypopnea syndrome (OSAHS) patients with different severity.METHODSThe clinical data of 113 subjects who had been diagnosed OSAHS or normal by polysomnography (PSG) between 2013 and 2014 in our department were retrospectively studied. They were divided into normal control group (AHI<5/h, 41 patients), mild to moderate OSAHS group (5/h30/h, 40 patients). PSG data of AHI and ODI in different body position in each group were further analyzed.RESULTSIn normal group, The AHI and ODI in supine position were significantly higher than that in the left or right lateral position, and the difference between the left and right lateral position was not significant. In the mild to moderate OSAHS group, the AHI and ODI in supine were higher than that in the left lateral position slightly, while the data in supine was higher than that in the right lateral position significantly. In the severe group, the data between the supine and the left lateral position was not statistically different, while the supine position data was higher compared with that of the right lateral position. CONCLUSIONAHI and ODI were higher in supine position than that in lateral position, while the AHI and ODI in right lateral position is higher than that in left lateral position in OSAHS patients with different severity. The ODI and AHI are consistent in reflecting the severity of the OSAHS.

Objective To explore an effective method of isolating and culturing the vascular endothelial cells of rat thoracic aorta.MethodThe thoracic aorta was harvested under aseptic condition from the thorax of a Wistar rat.The peripheral connective tissue and fat of the thoracic aorta were stripped and disposed,and then the thoracic aorta was turned inside out to expose the intima.The thoracic aorta was ligated with silk and cauterized on both ends with heated forceps.Then the thoracic aorta was cultured in medium DMEM/F12 containing 20% newborn calf serum in a 50 ml culture bottle which was already blanketed with rat tail collagen.The thoracic aorta was discarded and the new culture medium was added into the culture bottle six days later.The migrating cells were differentially digested by 0.125% pancreatic enzyme for serial subcultivation.The cells were identified by immunohistochemical method with anti-Ⅷ factor antibody.ResultA small amount of cells were seen to migrate from the aorta and adhered to the bottom of culture bottle 6 days after cultivation;the migrating cells spread to cover most part of the bottom of culture bottle 12-14 days later.About 70% of the migrated cells were in a confluent monolayer.The confluent cells grew rapidly after being digested with pancreatic enzyme,and they showed a typical cobblestone appearance.The cells were identified as endothelial cells with 100% expression of Ⅷ factor,which was regarded as the marker of endothelial cells.ConclusionThe method established in the present study is simple and easy to handle,it does not need collagen enzyme and endothelial cell growth promoting substrate,and it is economical and applicable.It is especially suitable for isolation and cultivation of vascular endothelial cells of vessels of small caliber.

Objective:To evaluate the effect of presurgical nasal mode(PNM)combined with nasal diorthosis in the treatment of na-sal deformity and incomplete unilateral cleft lip(IUCL)in infants.Methods:35 infants with IUCL were treated by PNM followed by nasal diorthosis and cheiloplasty.The nasal asymmetry was analysed by measurments of nostrils height,nostrils width and nasal colu-mella angle skewness on the photographs at the initial visit(T0),pre-operation(T1),1 week after operation(T2),1 month after opera-tion(T3)and a year after operation(T4).The other 35 infants with IUCL without PNM treatment were served as the controls.Re-sults:Compared with the controls,the symmetry of nostrils height,nostrils width,nasal columella angle skewness in PNM treated children were significantly improved at T0-T1 and T1-T2(P ＜0.05).there was no significant difference at T2-T3 and T3-T4(P >0. 05).Conclusion:Nasal asymmetry can be improved by presurgical nasal mode treatment followed by preliminary nasal deformity di-orthosis and cheiloplasty.

Objective To analyze the epidemiological characteristics of measles in the floating population in Daxing District from 2002 to 2015 and to provide a specific guidance for the control and preven-tion of measles. Methods The epidemiological characteristics of measles in the floating population in Dax-ing District were analyzed based on the data collected from Diseases Reporting Information System and Ques-tionnaires for measles cases. Results A total of 1 263 measles cases were reported in the floating population in Daxing District from 2002 to 2015, accounting for 73. 09% of all reported cases in that area. Among the 1 263 measles cases, 1 027 cases (81. 31%) were reported from March to June. The top 5 towns with high incidence of measles were Huangcun, Jiugong, Xihongmen, Yizhuang and Yinghai, from which 80. 29% of measles cases were reported. Age distribution of the measles cases showed that 145 cases were children younger than 8 months, 412 cases were children aged 8 months to 14 years old and the rest 706 cases were a-bove 14 years old. And of all cases, only 224 cases had measles vaccine immunization history. Conclusion It is necessary to maintain the high vaccination rate of 3 doses of measles vaccine by multi-approaches and increase the immunization rate in migrant workers. Moreover, strengthen the surveillance for measles is also an effective way for measles control and elimination.

OBJECTIVE: To analyze the differences of sleep respiratory parameters recorded by PSG and synchronous blood pressure measured by ambulatory blood pressure monitor between obstructive sleep apnea (OSA) patients with hypertension (HT) and simple OSA and simple HT; To determine the characteristics of sleep respiratory parameters and blood pressure changes in patient with OSA accompanied HT. METHOD: We chose the patients who were diagnosed simple HT (n=45) and simple OSA (n=50) and OSA with HT (n=56), Compared the sleep respiratory parameters and blood pressure changes between the three groups. Meanwhile the correlations about the sleep respiratory parameters and synchronization blood pressure were analyzed. RESULT: Compared with simple HT and simple OSA, OSA with HT has higher apnea hyponea Index (AHI) (P<0. 001), oxygen desaturation index (ODI), awake index (AI), wake after sleep onset (WASO) and the proportion of non-rapid eyemovement sleepl (N1) in total sleep time(TST), has lower mean arterial oxygen saturation (MSaO2), lowest arterial saturation oxygen (LSaO2), the proportion of slow wave sleep (SWS) and rapid eyemovement sleep (REM) in TST (P<0. 05). There were positive correlations between the systolic/diastolic blood pressure (SBP/ DBP) and AHI, ODI, AI, WASO and N1/TST (P<0. 05). Compared with simple OSA, the mean day systolic blood pressure (dMSP), mean night systolic blood pressure (nMSP), mean day diastolic blood pressure (dMDP), mean night diastolic blood pressure (nMDP) and mean night diastolic blood pressure (nMDP) were significantly decre- sed, meanwhile the difference between the average systolic/diastolic blood pressure day and night were significantly increased after continuous positive airway pressure (CPAP) treatment. OSA with HT has higher There were negative correlations between the SBP/DBP and MSaO2, LSaO2 (P<0. 05). Blood pressure mainly changed in the later sleep stage when the REM phase was increased. Blood pressure changes were characteristic of increasing DBP and decreasing SaO2. CONCLUSION There are significant differences between simple OSA and OSA with HT in the sleep respiratory parameters, which are closely related with changes of blood pressure in sleep stage; AHI is the high risk factor of the OSA with HT. PSG is a effective factor in estimating the OSA accompanied HT course of development and prognosis.

Objective:To investigate the clinical characteristics and prognosis of Philadelphia (Ph) chromosome-positive chronic myeloid leukemia (CML) patients with additional chromosomal abnormalities.Methods:The data of 351 CML patients with Ph-positive in the Affiliated Hospital of Qingdao University from January 2009 to January 2019 were retrospectively analyzed. The bone marrow chromosomal karyotype analysis of all patients was performed by using R-banding technique. The clinical characteristics and karyotype of Ph-positive CML patients with additional chromosomal abnormalities at initial diagnosis were summarized, and Kaplan-Meier was used to analyze the differences in overall survival (OS) of patients with different karyotypes.Results:Among 351 patients with Ph-positive CML, 32 (9.1%) cases had variant translocation. At initial diagnosis, 47 cases had additional chromosomal abnormalities including 29 cases in chronic phase accounting for 9.15% (29/317) of all patients in chronic phase, 3 cases in accelerated phase accounting for 25.00% (3/12) of all patients in accelerated phase, 15 cases in blast crisis accounting for 68.18% (15/22) of all patients in blast crisis; there was a statistically significant difference in the chromosomal abnormalities rate of all different phases ( χ2=50.799, P<0.05). Among 47 Ph-positive CML patients with additional chromosomal abnormalities, 13 patients had complex karyotypes with more than 3 additional chromosomal abnormalities, the proportion of complex karyotypes in chronic phase, accelerated phase and blast crisis was 13.79% (4/29), 33.33% (1/3) and 53.33% (8/15), respectively, and the difference was statistically significant ( χ2=9.26, P<0.05). The study showed that the most common additional chromosomal abnormalities in chronic phase were double Ph (48.28%, 14/29) and -Y (10.34%, 3/29), while the most common chromosomal abnormalities in the blast crisis were +8 (26.67%, 4/15) and double Ph (26.67%, 4/15). Kaplan-Meier survival analysis showed that at initial diagnosis the OS time of patients with additional chromosomal abnormalities was worse than that of those with the non-additional chromosomal abnormalities group ( χ2 = 61.138, P<0.05). The OS of patients with complex karyotypes for Ph - positive CML patients with additional chromosomal abnormalities at initial diagnosis was worse than that of patients with non-complex karyotypes, and the difference was significant ( χ2 = 4.945, P < 0.05). Conclusions:The additional chromosomal abnormalities is closely related to the progression of CML, and the prognosis of CML patients with additional chromosomal abnormalities is poorer than that of patients with only Ph translocation. Moreover, the more complex the additional chromosomes are, the more likely blastic changes are, and the poorer prognosis. And additional chromosomeal abnormalities during the treatment of CML patients may also lead to the progression of blastic changes.

OBJECTIVETo provide theoretical basis for artificial cross breeding of Angelica dahurica from Sichuan and Hebei Province, the characteristics of stigma receptivity and the viability and life-span of pollen were studied.

METHODThe viability and life-span of pollen were evaluated by TTC (2, 3, 5-triphenyl tetrazlium chloride) test, and the stigma receptivity was estimated by benzidine-H2O2 method.

RESULTThe pollen viability of A. dahurica from Sichuan and Hebei provinces was increased gradually since the bud stage, but those levels had since subsided after the pollen release from craze antheral. There was a little difference in the pollen viability of A. dahurica from Sichuan at different branches. While the order of the pollen viability of A. dahurica from Hebei was main stem < first-order branching < second-order branching. At room temperature, the pollen viability of both decreased during time of anthers dehiscing but also above 50% after 5 days. Compared with 4 degrees C and room temperature, conservation at - 20 degrees C could extend life of the pollen. The stigma had receptivity in 4th day and reached the highest level in the 6th day after blooming.

CONCLUSIONThe optimum artificial pollination times of A. dahurica was 6 days after blooming and choose the pollen in the peak stage of anthers dehiscing.

Objective To study the risk prediction for new intracerebral hemorrhage (ICH) with high sensitivity C-reactive protein ( hs-CRP) level. Methods In a retrospective, nested, case-controlled study, 323 cases of ICH were identified and matched with 646 controls. The hs-CRP levels at baseline were compared between the two groups. The relevance of different hs-CRP levels and the risk of ICH were analyzed. Results The ICH group had a higher median hs-CRP levels (1.10 mg/L) as compared with the control group (0. 66 mg/L) with significant difference ( P<0.01 ). In addition, the increase of risk associated with hs-CRP levels was primarily observed in the individuals with the highest quartile of hs-CRP levels(>2.12 mg/L). These patients had an increased risk of ICH (OR 2. 58, 95% CI 1. 77 to 3. 76) as compared with those in the lowest quartile(≤=0.30 mg/L). Individuals with basiline hs-CRP levels above the specified cut point of 3 mg/L ormore and those in the 80th percentile were at a markedly increased risk of ICH (for specified cut point of 3 mg/L,0R2.26, 95% CI 1.60-3.20, P<0.01; for 80th percentile, OR 2.24,95% CI 1.60-3.13, P <0.01, respectively). Conclusions Risk of ICH might be predicted with the level of hs-CRP. With the increase of hs-CRP level at baseline, the risk of ICH was increased.

OBJECTIVE: To observe the clinical effect of nasal surgical expansion as basical surgical treatment of patients with OSAHS. METHOD: A total of 320 patients with OSAHS were retrospectively analyzed. The patient was diagnosed by PSG. The electronic nasopharyngolarygnoscope exam airway CT, and MRI were applied to determining the nasal plane block. According to the concrete reasons, the nasal endoscopic nasal septum corrective surgery and open surgery were carried out, respectively. Nasal sinus neoplasm resection of off shoring, inferior turbinate fracture surgery or inferior turbinate back-end 1/3 line expansion and low temperature plasma ablation of nasal surgery, respectively. Pittsburgh sleep quality index (PSQI), snore outcome survey (SOS), epworth sleepiness score (ESS), the lowest arterial oxygen saturation (LSaO2) and AHI, time and ratio of slow wave sleep (SWS) stage and rapid eye movement (REM) stage were applied to comparing the curative effect between pre-operation and post-operation periods. RESULT: Snoring, sleep apnea, subjective mental symptoms of all patients with OSAHS were improved after operation; PSQI, SOS and ESS score were improved compared to pretreatment (P < 0.05); according to the 2009 OSAHS diagnosis and curative effect evaluation standard, 38 cases cured, 189 cases had obvious effect, 93 cases effective, and the total effective rate was 100%; there was statistical difference between the pre-operative period and 6 months post-operative in PSQI, SOS and ESS, LSaO2, AHI and proportion of REM (P < 0.05); sleep structure was improved, time and proportion of SWS were increased after the operation (P < 0.05). CONCLUSION Solving the problem of nasal airway obstruction is the first step in surgical treatment of patients with OSAHS.
