Objective To observe the effect of obstructive sleep apnea syndrome (OSAHS) patients with glycosylated hemoglobin (HbA1c) levels, assessment of continuous positive airway pressure (CPAP) effect on the level of HbA1c in patients with OSAHS. Methods From January 2013 to December 2016, eighty patients with OSAHS were divided into mild group, eighteen cases, moderate group twenty cases, severe group forty-two cases according to the apnea hypopnea index (AHI). Thirty healthy subjects were chosen as the control group. All the treatment groups were treated with CPAP for three months. Overnight polysomnography and HbA1c test were performed before and after treatment, and the control group was examined by HbA1c before treatment. Results The level of glycosylated hemoglobin in the middle and severe group was higher than that of the control group(P<0.05). After treatment, the glycated hemoglobin levels in the moderate and severe groups were significantly lower(P<0.05), and the sleep apnea hypopnea index, the lowest SaO2 and the average SaO2 level were significantly improved(P<0.01). Conclusion Glycated hemoglobin levels increased significantly in patients with moderate and severe OSAHS, and decreased HbA1c levels in patients with moderate and severe OSAHS after CPAP treatment.

[ ABSTRACT] AIM:To investigate the potential role of exogenous hydrogen sulfide ( H2 S) and ATP-sensitive po-tassium ( KATP ) channels in chronic stress-induced colonic hypermotility.METHODS:Male Wistar rats were divided into water avoidance stress ( WAS) group and sham WAS ( SWAS) group.Organ bath recordings were used to test the contrac-tile activity of colonic strips.The effects of H2 S donor NaHS and pretreatment with glibenclamide on the contractions of co-lonic smooth muscle were studied and the IC50 of NaHS was calculated.The localization and expression of the subunits of KATP channels were determined by the methods of immunohistochemistry and Western blotting.RESULTS:WAS increased contractile activity of colonic strips.NaHS concentration-dependently inhibited the spontaneous contractions of strips from the SWAS and WAS rats.The IC50 of NaHS for longitudinal muscle ( LM) and circular muscle ( CM) of the WAS rats was 0.2033 mmol/L and 0.1438 mmol/L, significantly lower than those of the SWAS rats.Glibenclamide significantly in-creased the IC50 of NaHS for LM and CM from the SWAS and WAS rats.In both SWAS and WAS rat colon, Kir6.1, Kir6.2 and SUR2B were expressed on the plasma membrane of the smooth muscle cells.WAS treatment resulted in up-reg-ulation of the expression of Kir6.1 and SUR2B in the colon devoid of mucosa and submucosa.CONCLUSION: The in-creased expression of Kir 6.1 and SUR2B in colonic smooth muscle cells may be a defensive response to chronic WAS.H2 S donors may have potential clinical effect on treating chronic stress-induced colonic hypermotility.

Objective To explore the clinical features of sentinel polyps (rectal polyps with proximal colon carcinoma) and its correlation with proximal colon carcinoma.Methods From January 2003 to December 2013,the clinical features of 963 hospitalized patients with rectal polyps were retrospectively analyzed.According to whether the patient with colon carcinoma,the clinical data of rectal polyps patients were divided into pure polyps group (n=855) and sentinel polyps group (n 108).The characteristics under endoscopy,clinical pathological features,treatment and prognosis of the two groups were observed.Chi square test was performed for differences comparison between groups.Results The length of stay in hospital of 963 patients was from four to 33 days,the average age was (49.7 ± 9.4) years,and the majority of the patients were male (n=610,63.3％).A total of 785 patients (81.5％) had non-specific abdominal symptoms,such as frequency or habit change of defecation,hematochezia,abdominal pain,abdominal distension.The relatives within three generation of 78 patients (8.1 ％) were diagnosed with tumor and some relatives of the patients diagnosed with familial adenomatous polyposis (2.2％,21/963).The positive rate of tumor marker of sentinel polyps group was higher (69.4％,75/ 108) than that of pure polyps group (6.8％,58/855; x2 =316.285,P＜0.01).The proximal colon carcinoma of patients with sentinel polyps appeared as neoplasma with circumferential growth,there was no specific appearance between distal rectal polyps and proximal colon carcinoma.When compared with pure polyps group,most polyps of sentinel polyps group were in maximum diameter over 1 cm (61.1％ (66/108) vs 46.9％ (401/855)),multi polyps (n＞5,38.9％ (42/108) vs 11.8％ (101/855)) and adenomatous polyp (83.3％ (90/108) vs 35.6％(304/855),x2=7.752,55.595 and 90.544,all P＜ 0.01).Majority of the proximal colon carcinoma with rectal polyps was papillary adenocarcinoma and tubular adenocarcinoma which was account for 75.9％ (82/108).Some were mucinous carcinoma and signet ring cell carcinoma.Most of the proximal colon carcinoma with rectal polys did not penetrate the serosa layer (Duk A-+Duk B,59.3％,64/108) and with little distant metastasis (Duke D,17.6％,19/ 108).Ninty-five point six percent (817/855) of patients with pure polyps underwent endoscopic treatment and all of them were cured and discharged.Forty-one point seven percent (45/108) of patients of sentinel polyps group accepted the radical operation and 19.4％ (21/108) received endoscopic submucosal dissection.Conclusions If multiple,maximum diameter over 1 cm and adenomatous rectal polyps were detected under colon endoscope,the possibility of carcinogenesis of the polyps or the proximal colon should be awared.If the endoscope is difficult to go further or the patient can not tolerate the whole colon examination,the patient should be followed up in short-term and complete the whole colon examination.

Objective To investigate the influence of chronic pain on the sleep quality in the patients with Parkinson′s disease (PD) .Methods 232 cases of PD in the neurology department of this hospital from March 2009 to March 2013 were selected and di‐vided into the pain PD group (PPD group ,106 cases) and the non‐pain PD group (NPPD group ,126 cases) according to whether accompanying chronic pain .Contemporaneous 140 individual of healthy physical examination were selected as the control group .The Pittsburgh Sleep Quality Index Scale (PSQI) and the fatigue scale (FS‐14) were used to judge whether sleep disorders existing . Then the differences in the sleep quality and fatigue condition were compared among three groups .The related factors of sleeping disorders were also analyzed .Results The scores of PSQI and FS‐4 had statistically significant differences among 3 groups (P<0 .05) ,in which the differences in the aspects of sleep latency ,subjective sleep quality ,sleep continuity ,habitual sleep efficiency and sleep disorders also were statistically significant (P<0 .05) .The influencing factors of sleeping disorders were the Hoehn‐Yahr stage (r = -0 .79 ,P<0 .05) ,dopamine dose (r = -0 .38 ,P=0 .04) ,presence of pain (r = -0 .57 ,P<0 .05) and severity of de‐pression (r = -0 .63 ,P<0 .05) .Conclusion The PD patients accompanying pain are more susceptible to develop sleep disorders , the sleep quality accompanying pain is worse than that without accompanying pain .Therefore the early intervention should be well conducted in clinic .

Objective:To investigate the effects of modified Sijunzi Decoction on myelosuppression in moderate- and advanced-stage lung cancer patients with Qi and Yin deficiency and analyze the underlying mechanism. Methods:A total of 100 moderate- and advanced-stage lung cancer patients with Qi and Yin deficiency who received treatment in Lishui Hospital of Traditional Chinese Medicine, China were included in this study. They were randomly assigned to receive chemotherapy with paclitaxel combined with cisplatin (control group, n = 50) or treatment with modified Sijunzi Decoction based on chemotherapy with paclitaxel combined with cisplatin (observation group, n = 50). Myelosuppression, traditional Chinese medicine symptom score, cellular immune function, serum levels of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor, and the dosage of recombinant human granulocyte-colony stimulating factor. Results:After treatment, the incidence of leucopenia, thrombocytopenia, hemoglobinopenia and neutropenia in the observation group were 60% (30/50), 18% (9/50), 18% (9/50) and 62% (31/50), respectively, which were significantly lower than those in the control group [90% (45/50), 30% (15/50), 32% (16/50) and 92% (46/50), χ2 = 6.979, 7.025, 6.534, 6.134, all P < 0.001]. The complete remission rate in the observation group was significantly higher than that in the control group [30% (15/50) vs. 8% (4/50), χ2 = 9.018, P < 0.001]. The traditional Chinese medicine symptom score in the observation group was significantly lower than that in the control group ( t = 6.982, P < 0.05). CD 8+, CD 4+ and CD 3+ levels in the observation group were (25.16 ± 2.87)%, (38.76 ± 4.16)%, (48.83 ± 5.61)%, respectively, and they were (28. 89 ± 4.02)%, (34.10 ± 4.59)%, (41.12 ± 77)%, respectively in the control group. There were significant differences in CD 8+, CD 4+ and CD 3+ levels between the observation and control groups ( t = 6.392, 6.235, 5.983, all P < 0.05). The dosage of recombinant human granulocyte-colony stimulating factor in the observation group was significantly lower than that in the control group [(2 567.34 ± 308.25) μg vs. (3 917.82 ± 411.67) μg, t = 11.258, P < 0.05]. Serum levels of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor were (25.53 ± 7.86) ng/L and (278.34 ± 28.74) ng/L, which were significantly higher than those in the control group [(21.30 ± 3.12) ng/L, (204.17 ± 11.98) ng/L, t = 9.136, 8.856, both P < 0.05]. Conclusion:Modified Sijunzi Decoction for the treatment of moderate- and advanced-stage lung cancer patients with Qi and Yin deficiency can decrease the incidence of myelosuppression possibly through increasing serum levels of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor and improving the immune function.

Objective To analyze the clinical features of esophageal foreign body(EFB) difficult to remove by gastroscopy.Methods The clinical data of 159 patients with EFBs treated in Renmin Hospital of Wuhan University from January 2013 to April 2017 were analyzed retrospectively.Among 159 cases,the EFBs were removed by gastroscopy in 101 cases(gastroscope group)and removed by non-gastroscope method in 58 cases (non-gastroscope group),including 42 cases removed by esophagoscopy and 16 cases by surgery.The general information of patients,the types of EFB,the condition of impaction,treatments and outcomes of the two groups were analyzed.Results There was no significant difference in age and sex between gastroscope group and non-gastroscope group (P ＞ 0.05).The food typeEFBs included fish bone (n =77),chicken bone (n =45),jujube seeds (n =15),food bolus (n =4);and the non-food type FEBs included spectecleslens (n =2),bottle cap (n =11),denture (n =5).More than one half of FBs were located in the upper esophagus:63.4％ (64/101) in gastroscope group and 66.7％ (28/42) in esophagoscope subgroup;however,EFBs were mostly located in the middle esophagus in surgery subgroup (62.5％,10/16).In gastroscope group and esophagoscope subgroup,the sharp EFBs of length-diameter ＞ 2 cm were rare(n =4,3.9％ and n =3,7.1％),but were common in the surgery group (n =9,56.3％).The EFBs were successfully removed in all patients without massive hemorrhage or death.In gastroscope group (n =101),93 cases had mucosal abrasion and bleeding,5 cases had mild active bleeding,and 1 case had esophageal fistula.In surgical removal (n =16) there were 4 cases of esophageal perforation and postoperative inflammation,3 cases of mediastinal inflammation and 2 cases of mediastinal abscess.Inesophagoscopic removal group (n =42),there were 2 cases of esophageal muscle layer abscess,1 case of esophageal fistula and 1 case of pulmonary infection.Conclusions The most common type of EFBs is of food source.Foreign bodies in the upper and middle segments of the esophagusare difficult to remove with gastroscopy.In case of a sharp foreign body embedded in the middle esophagus,surgical removal is preferred to avoid severe sequences.

Objective To discuss the values of three screening methods for the detection of early breast cancer,and to analyze the features of the screening cancer.Methods The first screening of breast cancer were performed in 5307 women who aged from 20 to 76 years with median age of 49 years.The three screening methods included physical examination with ultrasound and mammography,physical examination with mammography and mammography only.The rate of recall,biopsy,cancer detection of three methods were analyzed and the mammographic findings were reviewed Chi-square test or Fisher's exact test were used for the statistics.Results The recall rates were 4.90% (49/1001),6.90%(166/2407)and 4.48% (85/1899) in three methods respectively,the biopsy rates were 1.60% (16/1001),1.04% (25/2407) and 0.63%(12/1899),the cancer detection rates were 0.50% (5/1001),0.17% (4/2407) and 0 (0/1899).There were statistical differences among the three groups (X2=12.99,6.264,8.764,P < 0.05).Physical examination with ultrasound and mammnography had the highest cancer detection rate,ten breast cancers were detected and 8 were early stage breast cancer.Of seven cancers detected by mammography,only two were found by ultrasound.A cluster of calcifications were found in 2 cases,linear calcifications in 2 cases.One case presented as a asymmetric density,one as a asymmetric density with calcifications,one as multiple nodules with a duster of calcifications.Two breast cancers presented as asymmetric density were missed on mammography and diagnosed correctly after retrospective review.Conclusion Physical examination with ultrasound and mammography is the best method for breast cancer screening.The breast cancer can be detected by mammography earlier than other methods.

Objective:To explore the definition and implications of occupational attractiveness among long-term caregivers.Methods:The Walker and Avant concept analysis method was used to define the concept of occupational attractiveness among long-term caregivers.Results:Attributes of occupational attractiveness of long-term caregivers were: (ⅰ) a strength or ability; (ⅱ) mutual attraction between long-term care occupations and incumbents and potential job seekers; (ⅲ) to attract potential job seekers and satisfying their willingness to work; (ⅳ) to retain and motivate in-service long-term care personnel, and enabling them to develop the professional identity and career development.Conclusions:This concept is defined from the perspective of nursing practice in the elderly care service industry in China and combined with the characteristics of long-term caregivers at this stage. It provides clear conceptual support for further relevant research, and provides certain theoretical and practical guidance for the long-term care work of elderly care institutions, communities and families in China.
