Objective To observe the effect of emotion regulation on anxiety in patients undergoing functional endoscopic sinus surgery (FESS) under acupuncture-drug compound anesthesia.Method Ninety patients who were going to receive FESS were randomized into group A, B and C, 30 cases in each group. Acupuncture-drug compound anesthesia [electroacupuncture at Yingxiang (LI 20) and Yintang (GV 29)] was adopted in the three groups, ordinary doses of anesthetic drugs for group A and B (1% Tetracaine hydrochloride injection 100 mg+2% Lidocaine hydrochloride injection 0.1 g+Adrenaline hydrochloride injection 2 mL) and reduced doses for group C (1% Tetracaine hydrochloride injection 70 mg+2% Lidocaine hydrochloride injection 0.1 g+Adrenaline hydrochloride injection 2 mL). Conventional nursing was applied to group A, while specific emotion regulation was additionally adopted in group B and C during the perisurgical period. The three groups were evaluated by using Zung's Self-rating Anxiety Scale (SAS) prior to the surgery, 24 h and 48 h after the surgery, and the satisfaction ratings of the patients towards the surgery, anesthesia and nursing were compared.Result The SAS score 48 h after the surgery was significantly different from that before the surgery in group A (P<0.05). The SAS scores 24 h and 48 h after the surgery were significantly different from the score before the surgery in group B and C (P<0.05); the score 48 h after the surgery was significantly lower than that 24 h after the surgery in group B and C (P<0.05). 24 h and 48 h after the surgery, the SAS scores in group B and C were significantly different from those in group A (P<0.05). The satisfaction ratings of nursing in group B and C were significantly higher than the rating in group A (P<0.05). Conclusion Specific emotion regulation can effectively mitigate the anxiety of patients undergoing FESS under acupuncture-drug anesthesia, and improve the satisfaction rate of patients towards nursing.

Objective To investigate the difference in the pass rate of intensity?modulated radiation therapy ( IMRT) planning in patients with different tumors and its value in determining pass rate thresholds. Methods A total of 35 verified IMRT plans for each of esophageal cancer, nasopharyngeal carcinoma, breast cancer, cervical cancer, and lung cancer were selected consecutively, and a one?way analysis of variance was used to investigate the difference in pass rate. A single pass rate threshold was used to test all IMRT plans, and the pass rate thresholds of IMRT plans for different tumors were calculated based on normal distribution law. Results There was a significant difference in the means between the 5 groups of data ( F=35. 83, P<0. 01) , and there was also a significant difference between any two groups ( P=0. 000) . There were statistically significant differences between nasopharyngeal carcinoma group and other four groups ( P=0. 000) . The difference was not only significant between the breast cancer group and the esophageal cancer group ( P=0. 001) , but also between the breast cancer group and the lung cancer group ( P=0. 033) . The calculated results of each threshold were 93. 37%, 89. 34%, 97. 68%, 95. 99%, and 95. 42%, respectively. Conclusions Different thresholds should be used for IMRT plans for different tumors, and the normal distribution law can be used to calculate the threshold.

Two patients with typical Gitelman syndrome were diagnosed by gene and their clinical data and endocrine and metabolic status were evaluated.The etiology,clinical manifestation,laboratory findings,genetic diagnosis,and treatment for Gitelman syndrome were reviewed.

Kiss1 gene encodes Kisspeptins,an intercellular signal peptide whose corresponding receptor is Kiss1R. The initial study found that the Kiss1/Kiss1R system has the effect on inhibiting tumor metastasis. More and more evidence suggests that it can act on the hypothalamic-pituitary-gonadal(HPG) axis and is the key to puberty initiation and progression. It plays an important role in the neuroendocrine regulation of reproduction. In this paper, we reviewed the studies on Kiss1/Kiss1R system,its intracellular signal transduction pathway,role on HPG axis,and clinical application.

Objective To explore the clinical regularity of drugs on epidemic encephalitis B with text mining technique. Methods The data set on epidemic encephalitis B was downloaded from CBM database. The regularities of Chinese herbal medicine, Chinese patent medicine (CPM), western medicine and the combination of CPM and western medicine on epidemic encephalitis B were mined by data slicing algorithm. The results are showed visually with Cytoscape 2.8 software. Results The main function of herbal pieces was focused on clearing heat and removing toxicity. The herbal pieces such as Rehmanniae Radix Isatidis Raxis, Isatids Folium, Paeoniae Radis rubra and Scutellariae Radix were most often used. Angong Niuhuang Wan and Qingkailing Injection were usually used as CPM. For western medicine, antiviral drugs such as interferon and ribavirin were often used, and they were often used together with brain cells nutrition medicine, hormone, immunopotentiator and so on, and they were also frequently used together with CPM such as Angong Niuhuang Wan and Qingkailing Injection. Conclusion Text mining approach provides an important method in exploring the medication regularity for diseas, and provide refenrence for clinical use.

OBJECTIVETo compare the antitussive activity of three kinds of Stemonae Radix specified in the Chinese Pharmacopoeia, including roots of Stemona sessilifolia, S. japonica and S. tuberosa.

METHODThe antitussive activity was determined in mouse after cough induction by ammonia aerosol stimulation and the number of cough in 2 min were detected with codeine as positive control.

RESULTAll the decoctions, the total alkaloid fractions and non-alkaloid fractions of S. sessilifolia, S. japonica and three chemical types of S. tuberosa showed significant antitussive effect and exhibited a dose-dependent inhibition of coughing. The ED50 values showed that the antitussive activity strength for both total alkaloid fractions and the decoctions are: S. tuberosa (Type I) > S. sessilifolia > S. japonica. The total alkaloid fractions had more potent atitussive activity than the decoctions and non-alkaloid fractions. The antitussive activity strength for the three chemical types of S. tuberosa is: Type I > Type III > Type II. The samples from different producing areas for the same species of Stemonae Radix had no significant differences in antitussive activity. The result also showed that the honey-processed slice had much stronger antitussive activity than raw slice.

CONCLUSIONThe antitussive efficacies of Stemonae Radix were influenced by chemical diversity both in same species and among different species, different fractions and processed method.

Objective To compare the differences in the intestinal microflora of WHBE rabbit and JW rabbit models of diarrhea-predominant irritable bowel syndrome(IBS). Methods 16 WHBE rabbits and 16 JW rabbits were randomly divided into normal control(NC)group and IBS model group, respectively(n=8). The diarrhea-predominant IBS model was established by wet-heat stress combined with intragastric gavage of senna decoction. The abdominal circumference index,water content of feces and colonic transit function were observed. After sacrifice,colon tissue samples were taken for histopathological examination and colon contents for intestinal flora diversity analysis. Results Compared with the NC group,the IBS model rabbits showed an increased abdominal circumference index and fecal water content,and a shortened colon transit time, but no obvious pathological changes were observed in the colon tissues. Meanwhile, the Shannon index and Chao1 index of IBS model rabbits were significantly decreased(P<0.05). According to the result of OTU classification analysis,Firmicutes and Bacteroidetes are the dominant bacteria in the intestinal microflora of rabbits. Compared with the NC group, the Firmicutes, Verrucomicrobia, Chloroflexi, Akkermansia, and Streptococcus in the WHBE rabbit IBS model group were significantly reduced(P < 0.05, P < 0.01), while Bacteroidetes and rc4-4 significantly increased(P < 0.05, P < 0.01). However, in the JW rabbit IBS model group, Eubacterium and Subdoligranulum were significantly increased(P< 0.05),while Lactobacillus,Coprobacter,Veillonella and Streptococcus were markedly decreased(P<0.05). Compared with the JW rabbit NC group,the abundance of Firmicutes,Odoribacter, Veillonella,Streptococcus,Oscillospira and Pseudoflavonifractor were significantly decreased(P<0.05, P<0.01), but Bacteroidetes,Verrucomicrobia,Eubacterium,Akkermansia and Coprobacter were significantly increased(P<0.05,P<0.01)in the WHBE rabbit NC group. Compared with the JW rabbit IBS model group, the abundance of rc4-4, Bacteroidetes,Coprobacter and Clostridium were significantly higher(P < 0.05, P < 0.01), while the Firmicutes, Dorea, Coprococcus and Subdoligranulum were significantly lower(P <0.05)in the WHBE rabbit IBS model group. Conclusions There is an intestinal microflora imbalance in rabbits with IBS, resulting in a decrease of microflora diversity. The changes of intestinal microflora in the WHBE rabbits and JW rabbits with IBS have their own characteristics, and have apparent differences.

Pituitary abscess is a rare but potentially life-threatening disease. Headache, visual disturbance, and hypopituitarism are the most common presenting symptoms of pituitary abscess. On magnetic resonance imaging(MRI), pituitary abscess may present as a round sellar cystic lesion, hypo- or isointense on T1 imaging and hyper- or isointense on T2 imaging with peripheral gadolinium enhancement. Diagnosis usually is made during surgical exploration when pus is found in a cystic lesion. The mainstay of treatment is transsphenoidal surgical resection in combination with antibiotic therapy, although a craniotomy approach is warranted in select conditions. Here we report 3 cases of pituitary abscess in our hospital and review the literatures.
