Objective:To observe the clinical effect and safety of desloratadine citrate disodium in the treatment of allergic rhinitis ( AR) . Methods:Totally 80 patients were randomly divided into the control group and the observation group with 40 ones in each. There was no difference in gender, age, duration of allergic rhinitis, classification of serological specificity IgE between the two groups (P>0. 05). The observation group was treated with desloratadine citrate disodium tablets 8. 8mg, po, qd. The control group was given loratadine 10mg, po, qd. The treatment course was 12 days. All the patients were not given corticosteroids and other antihistamines. The clinical symptoms and signs integral, curative effect and adverse drug reactions during the treatment were observed. Results: In the observation group, 23 cases were markedly effective, 13 cases were effective, 3 cases were ineffective, one case didn’ t finish the study, and the total effective rate was 92. 30%. In the control group, the above index was 10 cases, 18 cases, 10 cases, 2 cases and 73. 68%, respectively. There was statistically significant difference in the total effective rate between the two groups (P<0. 05). The symptoms and signs integral after the treatment in the observation group was significantly decreased compared with that in the control group, and the difference was statistically significant (P<0. 05). The incidence of adverse drug reactions in the observed group was obviously lower than that in the control group. Conclusion:Compared with that of loratadine, the clinical efficacy of desloratadine cit-rate disodium tablets is better in the treatment of AR with good safety.

Objective: To observe the clinical efficacy of moving cupping on the back for patients with chronic fatigue syndrome (CFS)-related sleep disorders. Methods: A total of 60 patients with CFS-related sleep disorders were randomized into a control group and an observation group, with 30 cases in each group. The control group was treated with oral administration of fluoxetine hydrochloride capsule. The observation group was treated with moving cupping on the back, once every other day. The efficacy was observed after 4 weeks of treatment. The fatigue scale-14 (FS-14) and Pittsburgh sleep quality index (PSQI) were assessed before and after the treatment to evaluate the clinical efficacy. Results: The total effective rate was 93.3％ in the observation group, and 73.3％ in the control group. The difference between the two groups was statistically significant (P<0.05). After treatment, the improvement of physical fatigue value, mental fatigue value, and the total score of FS-14 in the observation group were statistically different from those in the control group (all P<0.05). The scores of subjective sleep quality, sleep latency, habitual sleep efficiency, use of sleeping medication, daytime dysfunction of PSQI and the total score in the observation group were improved more significantly than those in the control group (all P<0.05). Conclusion: Moving cupping on the back can significantly improve sleep disorders in CFS patients, and it has a better curative effect than oral fluoxetine hydrochloride capsules.

Methods The clinical manifestations, laboratory examinations, therapeutic methods and prognosis of 15 TMA patients induced by malignant hypertension were analyzed retrospectively. Results The clinical manifestations were characterized by microangiopathic hemolytic anemia, thrombocytopenia and kidney injury. None of the patients required plasma exchange therapy. After antihypertensive treatment, all of 15 patients were discharged with improved clinical condition, remoglobin levels and platelet count. Conclusions The TMA induced by malignant hypertension is different from the classic TMA. Improving the understanding of TMA induced by malignant hypertension will contribute to early diagnosis and targeted treatment.

Objective To evaluate the therapeutic effectiveness and safety of endoscopic submucosal dissection(ESD)for early colorectal carcinoma and its precancerous lesions. Methods The clinical pathologi-cal characteristics,en bloc resection rate,curative resection rate,complications and follow-up results of 21 pa-tients with early colorectal carcinoma or precancerous lesions,who were treated by ESD,were retrospectively analyzed. Results Most lesions were located in left colon,which accounted for 80. 9%(17/ 21).The most com-mon macroscopic morphology(TypeⅠ)was protrusion type(61. 9%,13/ 21),while flat type was the least (14. 3%,3/ 21). The mean procedure time was 79(35-120)min. The en blot resection rate was 100. 0%(21/ 21),and curative resection rate was 85. 7%(18/ 21). Postoperative hemorrhage occurred in 1 patient (4. 7%,1/ 21)and postoperative infection occurred in 1(4. 7%,1/ 21)and no perforation was recorded. Tubu-lar adenoma with high-grade intraepithelial neoplasia(LGIEN)was the most occurence(33. 3%,7/ 21),villous adenoma with LGIEN was the least(4. 7%,1/ 21). No local recurrence or metastasis was observed during follow-up of 3-20 months. Conclusion ESD is safe,effective,minimal invasive for early colorectal carcinoma and its precancerous lesions,with optimistic prospect of clinical application.

Objective Serum abnormal prothrombin (PIVKA-Ⅱ) level was detected in pancreatic cancer patients and its clinical value in diagnosing and treating pancreatic cancer was explored.Methods A total of 112 pancreatic cancer patients,28 benign pancreatic diseases patients and 79 healthy controls were collected from Cancer Hospital of Hubei Province.Serum PIVKA-Ⅱ level was determined by chemiluminescent immunoassay (CLIA).CEA and CA19-9 level was detected by electrochemiluminescence immunoassay (ECLIA).Receiver operation characteristic (ROC) curve was drawn and the cut-off value was set.The sensitivity,specificity and accuracy were calculated.Results PIVKA-Ⅱ level in 112 pancreatic cancer patients was 39.0 (22.61,137.67)U/L[median (quartile range)],which was significantly higher than that in 30 patients with benign pancreatic disease [23.0 (17.32,29.67) U/L] and 79 healthy controls [21.21 (17.9,25.12) U/L].The differences were statistically significant (P＜0.01).However,there was no significant difference between benign pancreatic disease patients and healthy controls.ROC analysis showed that area under curve(AUC) for PIVKA-Ⅱ,CEA and CA19-9 was 0.793,0.707 and 0.849.The cut-off value for discriminating pancreatic cancer was established at 32.4,4.7 and 27.0 U/L for PIVKA-Ⅱ,CEA and CA19-9.The sensitivity was 61.6％,38.0％ and 66.1％,and the specificity was 86.3％,96.3％ and 89.9％,and the accuracy was 71.7％,62.3％ and 75.0％,respectively.The sensitivity,specificity and accuracy of PIVKA-Ⅱ combined with CEA and CA19-9 was 90.2％,76.0％ and 84.3％.The sensitivity was obviously higher,while the specificity was lower.Serum PIVKA-Ⅱ level was associated with advanced tumor stage.There were 20 patients who were followed up.PIVKA-Ⅱ level in 15 cases were decreased after surgery or interventional therapy (50.6 U/L vs 110.5 U/L,P ＜0.001),which was increased in 4 of the five cases who received palliative care to a various degree.Conclusions PIVKA-Ⅱ detection could benefit the diagnosis and prognosis monitoring of pancreatic cancer.
