Objective To discuss the signiifcance of serum albumin level in assessing severity, progress and prognosis of sepsis in children. Methods The clinical data of 212 patients diagnosed with sepsis admitted to PICU from February 2010 to July 2010 were retrospectively analyzed, and 52 patients had severe sepsis and 31 patients had septic shock. Meanwhile, 110 non-sepsis patients were selected as controls. The relationships of hypoalbuminemia with pediatric critical illness score (PCIS), pediatric risk of mortality III (PRISM III) and prognosis were evaluated, and the change of albumin level in patients with dif-ferent severity of sepsis was observed. Relative factors analysis of albumin level ≤25 g/L was performed. Results As the serum albumin level was decreased, the PCIS was signiifcantly decreased while the PRISM III was increased (P<0.01). The se-rum albumin level was signiifcantly different among children with septic shock, severe sepsis and sepsis and controls (F=13.938, P=0.000). The results of relative factors analysis showed that sepsis children with an albumin level≤25 g/L had more organ failures, higher mortality, longer hospital and PICU stay and more likelihood for ventilator support (P<0.01). Lower albumin levels were accompanied with lower rates of recovery and improvement but higher mortality (rs=-0.161, P=0.000). Conclusions Hypoalbuminemia can be used as indirect indicator for severity of infection. The albumin level≤25 g/L indicated the severity of illness and prognosis in children with sepsis.

A diving decompression procedure is a specific rule that divers should follow when they ascend and get out of water. It comes from the decompression theory and algorithm and is designed for the prevention of decompression sickness. With the ， ， development of diving technology and diving medicine the decompression procedures are constantly innovated and the new ， decompression procedure can be used in diving practice after safety verification. In principle the safety verification of ， decompression procedures should be conducted on animal experiments before human experiments and the risks of ， decompression sickness and oxygen toxicity should be systematically assessed. However the assessment methods used in ， ， ， different studies differ greatly thus it is urgent to establish a standard and universal verification system. Traditionally the risk ， ， assessment of decompression sickness and oxygen toxicity is mainly carried out by observing the incidence detecting bubbles ， theoretical calculation and lung functional test. Furthermore biochemical indicators are increasingly becoming important ， ， supplements. Due to the special underwater environment the diving operation is prone to accidents. Therefore in addition to ， verifying the safety of the new decompression procedure exploring its safety decompression limit is of great significance for the formulation of emergency decompression procedures in emergency situations. The specific approach is to shorten the decompression time and assess the safety until the critical time for detecting bubbles without the occurrence of decompression ， ， sickness is found. Future studies should continue to optimize safety assessment methods explore sensitive biochemical markers ， clarify species associations and improve verification efficiency and reliability of results.

ObjectiveTo explore the effect of cluster needing of scalp point combined with rehabilitation techniques on acute cerebral infarction patient's movement disturbance.MethodsFugl-Meyer Measure, Bathel Index, Nerve function disturbance and clinical effect assessment methods were used to assess the motion function and daily living activity of cluster needling of scalp point group, rehabilitation group and cluster needling of scalp point combined with rehabilitation group.ResultsThe motion function and daily living activity of the cluster needling of scalp point combined with rehabilitation group patients were superior to cluster needling of scalp point group patients and rehabilitation group patients (P<0.01,P<0.05). The total effective rate can reach to 97.14%. Otherwise, cluster needling of scalp point combined with rehabilitation could also prevent food drop or inversion, subluxation of acromioclavicular joint, shoulder-hand syndrome, contracture of joint, mistake-use syndrome and abnormal motor mode.ConclusionThe cluster needling of scalp point combined with rehabilitation can improve the patients' living quality effectively.

OBJECTIVETo investigate the feasibility of using percutaneous K-wires fixation after manipulative reduction combining with gypsum or splint fixation for treatment of the Barton fracture of aged people.

METHODSFrom June 2011 to May 2013, 91 patients with closed and fresh Barton fracture were analyzed retrospectively which information was complete. According to different methods these patients were divided into three groups: 33 patients in group A were treated by simplex fixation of gypsum or splint after manipulative reduction, including 20 males and 13 females with an average age of (63.27 ± 5.83) years old; 35 patients in group B were treated by percutaneous K-wires fixation after manipulative reduction combining with gypsum or splint fixation, including 23 males and 12 females with an average age of (64.25 ± 4.53) years old; 23 patients in group C were treated by open reduction and internal fixation including 15 males and 8 females with an average age of (64.04 ± 4.83) years old.

RESULTSAll the patients were followed up for 10 to 16 months with an average of 12 months by the method of recheckging in outpatient clinic.

Objective To investigate the clinical features and disease-causing mutations of familial hypomagnesaemia with hypercalciuria and nephrocalcinosis.Methods In February 2016,a 24 year old female patient with left kidney stone and nephrocalcinosis in bilateral kidneys was admitted to our hospital.One month prior to this admission,she had been treated by PCNL to remove the most part of left kidney stone in otherhospital.Mter admission,She was found hypomagnesaemia (serum magnesium 0.65 mmol/ L) and hypercalciuria (24h urine calcium 364.0 mg) but with normal renal function (serum creatinine 101.5μmol/L).And the remained part of left kidney stone was removed by flexible ureteroscope.As she was considered probably with an autosomal recessive FHHNC,an analysis of CLDN16 and CLDN19 gene mutations was performed using her and her parents'peripheral white blood cells.Results Mutation analysis revealed this patient had two heterozygous mutations in the CLDN16.One is an one-base deletion mutation in the 123th codon in exon 2:368delA.The other is a missense mutation in the 139th codon in exon 2:416C →T which resulted in an amino acid change Ala139Val.Her parents respectively had one of each heterozygous mutation.In the six months follow-up,an oral administration with hvdrochlorothiazide,potassium citrate,and calcium magesium supplements significantly reduced her hypomagnesaemia (serum magnesiun 1.0 mmol/L) and hypercalciuria (24-h urine calcium 156.0 mg),and no stone recurrence and aggravation of nephrocalcinosis and renal dysfunction occurred.Conclusions We diagnosed a patient with FHHNC who had a novel compound heterozygous mutation of CLDN16.This rare disease should be suspected if there are three constant clinical features of hypomagnesaemia,hypercalciuria and nephrocalcinosis,and verified with CLDN16 and CLDN19 gene test.Currently the option for treatment of FHHNC is symptomatic treatment until severe deterioration of renal function.The hydrochlorothiazide,potassium citrate,and calcium magesium supplements may have considerable effects on hypomagnesaemia and hypercalciuria.

Objective To explore the impact of iodine nutrition on pregnant women before and after adjusting the iodine content in iodine salt.Methods Twelve counties (areas,cities) in Hangzhou were divided into urban,suburban and rural areas before and after adjusting the iodine content of salt.One survey spot was selected in each district and one hundred pregnant women were selected;family salt and urinary samples of each pregnant woman were collected.The levels of salt and urinary iodine were measured by the methods of picric sodium thiosulfate titrimetric (GB 13025.7-2012) and spectrophotometer (WS/T 107-2006),respectively.Results One thousand two hundred and thirty-nine and one thousand two hundred and thirty-three household salt samples were collected before and after adjusting the iodine content in iodine salt.The median of salt iodine of pregnant women (23.30 mg/kg) before adjusting the iodine content in iodine salt was lower than that after adjusting the iodine content in iodine salt (30.09 mg/kg,x2 =-4.71,P ＜ 0.01).The iodine salt coverage rate and the consumption rate of qualified iodized salt after adjusting the iodine content in iodine salt [93.92％ (1 158/1 233),93.84％ (1 157/1 233)] were higher than those before adjusting the iodine content in iodine salt [91.85％ (1 138/1 239),91.37％ (1 132/1 239),x2 =4.01,5.51,all P ＜ 0.05].The iodine salt coverage rate and the consumption rate of qualified iodized salt in urban and suburb areas after adjusting the iodine content in iodine salt [99.42％ (510/513),100.00％ (203/203),97.86％ (5021513),100.00％ (203/203)] were higher than those before adjusting the iodine content in iodine salt [86.71％ (450/519),98.00％ (196/200),77.26％ (401/519),85.00％ (170/200)],but the iodine salt coverage rate and the consumption rate of qualified iodized salt in rural area before adjusting the iodine content in iodine salt [94.62％ (492/520),86.92％ (452/520)] were higher than those after adjusting the iodine content in iodine salt [85.69％(443/517),76.98％ (398/517),x2=64.22,2.32,100.02,32.90,23.31,17.33,all P ＜ 0.05].One thousand two hundred and thirty-four and one thousand two hundred and thirty-one household urine samples were collected before and after adjusting the iodine content in iodine salt.The median of urinary iodine (MUI,114.80 μg/L) of pregnant women after adjusting the iodine content in iodine salt was lower than that before adjusting the iodine content in iodine salt (168.60 μg/L,x2 =36.92,P ＜ 0.01).The MUIs of pregnant women in urban,suburban,and rural areas (171.30,170.20 and 162.40 μg/L) before adjusting the iodine content in iodine salt were higher than those after adjusting the iodine content in iodine salt (101.00,149.48 and 119.90 μg/L,x2 =-7.78,-2.63,-6.28,all P ＜ 0.01).The differences of urinary iodine between groups were statistically significant in urban,suburban and rural areas after adjusting the iodine content in iodine salt (x2 =32.86,P ＜ 0.01),the MUI of pregnant women in urban areas was lower than those in the suburban and rural areas (x2 =6.70,8.13,all P ＜ 0.05).Conclusions After adjusting the iodine content of salt in Hangzhou,the iodine-nutrition level of pregnant women is decreased.But the consumption rates of qualified iodized salt and the MUIs in urban,suburb,rural areas are different,so the coverage of iodized salt at household level needs to be enhanced and the health education should be highlighted.
