Objective To investigate the clinical features and genetic basis of cryopyrin-associated periodic syndrome (CAPS). Methods The clinical manifestations, laboratory tests, and genetic tests of one case of CAPS were retrospectively analyzed. The related literatures were reviewed. Results A 7 year and eight month old male patient had recurrent fever for 7 years and his whole body was covered with patchy red rash which was itchy and faded with pressure. The limbs and joints were normal. The levels of high-sensitivity C-reactive protein, erythrocyte sedimentation rate, rheumatoid factors were increased. The patient had fundus arteriosclerosis, double conjunctival lesions and nerve deafness on both sides. There was no mutation found in NLRP3 gene coding region, but a heterozygous mutation (-2667G>T) had been found in 5 ' untranslated region. Compared with normal control, the mRNA level of NLRP3 increased 4.2 times and the expressions of IL-1βand IL-18 gene increased 2.2 (P=0.002) and 1.2 times (P>0.05). Conclusions The clinical features of CAPS can be recurrent fever, rash, and joint involved. The oph-thalmologic abnormalities and varying degrees of deafness may occur during the progression. The test of NLRP3 gene may help diagnosis.

Objective To investigate the effect of malignant tumor on neuromuscular block of cisatracurium. Methods Sixty ASA Ⅰ or Ⅱ patients with head and neck neoplasms (15 cases with benign tumor, 45 with malignant tumor), aged 18-64 yr, were randomly divided into 4 groups ( n = 15 each): Ⅰ benign tumor group (group B,3 × ED95 ); Ⅱ -Ⅳ different dose cisatracurium group (group C1 (2 × ED95 ), C2 (3 × ED95 ) and C3 (4 ×ED95)). Neuromuscular block was assessed with accelerograph F (TOF-watch SX). Single stimulation of ulnar nerve was used. Anesthesia was induced with TCI of propofol (target plasma concentration 3 μg/ml) and remifentanil (target effect-site concentration 3 ng/ml). Tracheal intubation was facilitated with cisatracurium 0.15 mg/kg in group B, and with cisatracurium 0.10, 0.15 and 0.20 mg/kg in group C1, C2 and C3 respectively. The onset time, clinical duration, time for recovery of T/Tc to 75 % and recovery index were recorded. Results The clinical duration, time for recovery of T/Tc to 75 % and recovery index were significantly longer in group C2 than in group B (P < 0.05). The onset time was significantly shorter, while the clinical duration and time for recovery of T/Tc to 75% were significantly longer in group C2 and C3 than in group C1 , and in group C3 than in group C2 ( P <0.05) .Conclusion The duration of action and recovery times of cisatracurium were prolonged in patients with malignant tumor.

Objective To explore whether albumin corrected anion gap (ACAG) is associated with long-term mortality of sepsis patients.Methods Adult patients with a diagnosis of sepsis within the first 24 hours (from December 2013 to December 2014) admitted to the intensive care unit (ICU) were included via the Sepsis database of West China Hospital Sichuan University. To record their long-term survival, patients were followed up by telephone interview one year after enrollment. ACAG was calculated according to the anion gap (AG) level within the first 24 hours admitted to ICU, and patients were divided into normal ACAG group (ACAG 12-20 mmol/L) and high ACAG group (ACAG > 20 mmol/L), and clinical characteristics and 1-year mortality were compared between groups. Patients were also divided into survivors and non-survivors according to the 1-year survival outcome, and multivariate logistic regression analysis was conducted to find independent risk factors for long-term mortality of sepsis patients.Results A total of 296 sepsis patients were enrolled in the study, with 191 (64.5%) in the high ACAG group and 105 (35.5%) in the normal ACAG group. There were no significant differences in age, gender, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), sequential organ failure assessment (SOFA), Charlson cormobidity index (CCI) and other background variables between groups. Compared with the normal ACAG group, patients who suffered from multiple organ dysfunction syndrome (MODS) in the high ACAG group were more prone to develop renal and gastrointestinal injury (43.5% vs. 25.7%, 52.9% vs. 33.3%, respectively), had significantly higher serum creatinine [SCr (μmol/L): 89.0 (61.0, 148.0) vs. 67.1 (48.0, 86.0)], greater need for continuous renal replacement therapy (CRRT, 16.8% vs. 6.7%), and significantly shorter length of ICU stay and hospital stay [days: 11 (5, 22) vs. 16 (18, 31), 21 (14, 39) vs. 28 (20, 47)], with statistically significant differences (allP < 0.05). It was shown by Kaplan-Meier survival analysis that 1-year cumulative survival for the high ACAG group was significantly lower than that of the normal ACAG group (55.0% vs. 67.7%,P = 0.046). It was shown by multivariate logistic regression that ACAG [odds ratio (OR) = 1.201, 95% confidence interval (95%CI) = 1.115-1.293,P = 0.000], APACHE Ⅱ (OR = 1.053, 95%CI = 1.011-1.098, P = 0.014), the incidence of septic shock (OR = 2.203, 95%CI = 1.245-3.898,P = 0.007), fungus infection (OR = 3.107, 95%CI = 1.702-5.674,P = 0.000), acute renal failure (OR = 2.729, 95%CI = 1.134-6.567,P = 0.025) and complicated with malignancy (OR = 2.929, 95%CI = 1.395-6.148,P = 0.005) were independent risk factors contributing to increased 1-year mortality among sepsis patients.Conclusion ACAG was an independent risk factor for 1-year mortality of sepsis patients.

Based on the ongoing clinical experiences at our outpatient pharmacy and geriatrics multidisciplinary inpatient and outpatient services,we believe that polypharmacy among elderly patients is serious and pervasive in China.This observation is supported by the findings from literature review.To help address this serious issue in senior care,we recommend to gain better understanding of age-related physiological changes of the elderly as well as those in pharmacokinetics and pharmacodynamics,and to conduct prescription review and medication reconciliation.The multi-and interdisciplinary approach employed by modern geriatrics care model,involving doctors,pharmacists and nurses,should further help address this issue and promote rational use of pharmaceuticals in the elderly patients.

After The Medical Institution Management Regulations was enacted by the State Council in 1994, 26 Chinese provinces and municipalities have enacted the local legislation of medical institution management.These local legislations make a full use of the space of legislation which the host law gives, reasonably determined the health administrative departments'management responsibilities at all levels, detailed the responsibility division for examina-tion and approval, and defined the medical institution practice behavior requirement.The local legislation has played a positive role for the rational medical resources allocation and standardized the local medical institutions practice or-der.But as time goes by and reform deeply, the weakness of these legislations has emerged.This is seen for the fact that they have not been repaired for many years, blindly repeat host law, heavily rely on the regulations with poor sta-bility , do not keep the pace with the system design times, violate the license law, and pay attention to the administra-tive examination and approval instead of the occupational behavior management.This paper makes full investigation on the existing relevant medical institution management laws, regulations and policies.Through the analysis of advan-tages and disadvantages of provincial legislations, some thinking on the medical institutions management is put for-ward.
