Objective To investigate the effect of types of pinch on the measurement of pinch strength in healthy young subjects.Methods All anthropometric factors of 20 right-handed young volunteers(10 males,and 10 females)were recorded.Their pinch strength in 3 types(I.e.Pulp2,Chuck,and Lateral)were measured with digital pinch dynamometer in standardized position.Results For both genders,the pinch strength of Lateral was the largest,followed by Chuck,Pulp2 and the dominant hand was stronger(P<0.01).Men were stronger than women in all types of pinch strength(P<0.01).Correlation among the 3 types of pinch strength were presented(r=0.568～0.707,P<0.01).The correlation were found between the pinch strength of 3 types and weight in women(r=0.764～0.807).No correlation has been found among the pinch strength of 3 types and age,height,the thickness of palm in both the males and the females.Conclusion The sex and types of pinch significantly impact pinch strength in healthy young subjects,but the correlation between pinch strength and anthropometry should be further surveyed.

Objective To observe the effects of stellate ganglion block (SGB) on humoral immunity func-tion in patients who received modified radical mastectory (MRM). Methods Eigty female patients were randomly divided into control group(group Ⅰ ,n =40) and intervention group (group Ⅱ,n =40). Blood samples were taken pre-intervention (T1), after intervention ( T2 ) and 30 rain after operation ( T3 ) for the determination of lgG, IgA, IgM. Results Compared with T1, IgG, IgA, IgM at T2 and T3 in two groups were lowered, IgG [ ( 11.8±2.2 ) g/L vs (9.5 + 1.5) g/L,t = 5. 4630,P =0.0041 ] and IgA [(1.9±0.3)g/L vs (1.7±0.4) g/L,t =2. 5298,P = 0.0134 ] at T3 in group Ⅱ were significantly different as compared with that of group Ⅰ ; IgM at T2 [ (2.5±0.8 ) g/L vs (2.1±0.6)g/L,t =2.8276,P=0.0072] and T3[ (2.1±0.5)g/L vs (1.6±0.5)g/L,t =4.4721,P = 0.0000 ] was significantly different between the two groups. Conclusions Preoperative-SGB can improve the inhibi-tion degree of humoral immunity caused by modified radical mastectory.

OBJECTIVETo discuss the treatment strategy of acetabular fractures and unstable pelvic fracture of the hip and to evaluate its outcome.

METHODSRetrospective analysis of clinical data in 32 patients with unstable pelvic fracture and acetabular fractures from January 2007 to June 2013 were collected. There were 18 males and 14 females aged from 18 to 62 years old (means 38 years old). According to Tile classification of pelvic fracture, 11 cases were type B1, 8 were type B2.1, 7 were type B2.2, 3 were type C1.1, 2 were type C1.2, 1 was type C3. According to Judet-Letournel classification, anterior column fracture was in 1 case, transverse fracture in 8, transverse plus posterior wall fracture in 6, T-type fracture in 1, anterior column plus half transverse fractures in 5, double column fracture in 11. Other combined injuries were treated early, the surgical operation were performed after stable condition. The hip joint function and the fracture reduction were assessed during follow-up.

RESULTSThe operative time was from 1.8 to 6.5 hours (averaged 3 hours). Two fat patients' incision occurred in fat liquefaction and healed after dressing, no incision infection happened. Only 1 case was lost to follow-up, 31 patients were followed up with a mean time of 23 months (6 to 42 months). The healing time of pelvic fracture was from 8 to 18 weeks (averaged in 10.6 weeks). The hip function was evaluated according to the Matta and Tornetta standard postoperatively, the result was excellent in 15 cases, good in 14 cases, fair and poor in 1 case respectively. The Majeed score of the hip function was 83.65? 7.67, the result was excellent in 15 cases, good in 12 cases and fair in 4 cases. The healing time of acetabular fractures was from 8 to 16 weeks (averaged in 10.2 weeks). The fracture reduction was assessed by Matta standard, the result was excellent in 15 cases, good in 12 cases and fair in 4 cases. The heterotopic ossification was evaluated by Brooker standard, 4 cases were grade I, 1 case was grade II . There were no infection, nonunion and necrosis of the femoral head in all patients. The nerve damage symptoms in 5 patients disappeared during 4 to 6 months after operation.

CONCLUSIONPatients with unstable pelvic fractures and acetabulum fractures were in a critical condition early, using the concept of damage control to save lives in a timely manner. Grasp the operation time in the late treatment, acetabulum fractures reach anatomical reduction as far as possible, pelvic fractures are given priority to stable reconstruction. The operation order was fixed pelvic ring first, according to the condition to choose the appropriate surgical approach and fixed mode.

Objective To investigate the diagnostic value of procalcitonin(PCT)as an early indicator for sepsis.Methods Serum levels of PCT and C-creative protein(CRP)and white blood cell (WBC)count were measured in 30 patients in critical condition hospitalized at an intensive care unit(ICU) with diagnosis of systemic inflammatory response syndrome(SIRS).They were divided into two groups, sepsis and non-sepsis,based on their clinical manifestations and results of lab tests.Blood specimen was collected from each patient for measurement of PCT,CRP and WBC count on the 1~(st),3~(rd)and 7~(th)day after hospitalization and bacteriological culture for blood and sputum,and chest X-ray was performed,as well. Acute physiology,age and chronic health evaluation(APACHE Ⅱ)was made on the 1~(st),3~(rd)and 7~(th)day after hospitalization to assess their ill condition.Their prognosis were judged on the 28~(th)day of the follow-up. Results Serum level of PCT increased significantly in the sepsis group(with the highest of 10.13 ng/ml), as compared with that in the non-sepsis group.Sensitivity,specificity and predictive value of a positive test for a cut-off value of serum level of PCT at 0.5 ng/ml were 97.0%,91.7% and 82.1%,respectively, which were all better than those of serum level of CRP and WBC count.Serum level of PCT in the patients was significantly associated with their prognosis,and PCT in those died was significantly higher than that in those survived.Whereas,serum level of CRP and WBC count elevated in both groups,but the difference between the two groups did not reach a level of statistical significance.Conclusion Serum level of PCT can be used as an early indicator for judgment of sepsis for a patient with infection and reflection of severity of illness.
