OBJECTIVETo compare the efficacy differences between needle-knife therapy and acupuncture-cupping for treatment of cervical spondylosis (CS) of cervical type.

METHODSSixty cases of CS were randomly divided into a needle-knife group (30 cases) and an acupuncture-cupping group (30 cases). The needle-knife therapy was applied at points among superior nuchal line of occipital bone, bilateral neck muscle, neck centerline, trapezius and medial border scapula for only once. In the acupuncture-cupping group, acupuncture was applied at Fengchi (GB 20), Fengfu (GV 16), Tianzhu (BL 10), Dazhui (GV 14), Jianjing (GB 21), Jiaji (Ex-B2, from C4 to C6), Houxi (SI 3) and Ashi point, followed by cupping on local skin, once every other day for totally six times. The score of neck stiffness and visual analogue scale (VAS) were observed before and after treatment, in follow-up of 1, 3 and 6 months after treatment in the two groups, and the efficacy was compared.

RESULTSIn the needle-knife group, 9 cases were cured, 12 cases were markedly effective, 8 cases were effective and 1 case was failed; the total effective rate was 96.7% (29/30) and the cured and markedly effective rate was 70.0% (21/30). In the acupuncture-cupping group, 8 cases were cured, 9 cases were markedly effective, 11 cases were effective and 2 cases were failed; the total effective rate was 93.3% (28/30) and the cured and markedly effective rate was 56.7% (17/30). The difference of total effective rate in the two groups was not statistically significant (P > 0.05), but the cured and markedly effective rate of needle-knife group was significantly superior to that of acupuncture-cupping group (P < 0.05). The needle-knife therapy was significantly superior to acupuncture-cupping on improvement of neck stiffness in the follow-up of 1, 3, 6 months after treatment (P < 0.05, P < 0.001); both treatments were effective on relief of neck pain, but the needle-knife group had better effects in the follow-up of 3 and 6 months after treatment compared with acupuncture-cupping group (both P < 0.01).

CONCLUSIONThe needle-knife therapy has better effects on neck stiffness and pain relief than acupuncture-cupping, and it is more treatment time saving.

Objective To evaluate serum Slit2 protein level in patients with chronic severe hepatitis B,and the re-lation with extent of liver damage and prognosis of patients.Methods In February-July 2014,patients with chronic hepatitis B(chronic hepatitis group)and chronic severe hepatitis B(chronic severe hepatitis group)in an infectious department were observed,healthy volunteers were as control group,and patients in chronic severe hepatitis group were subdivided into recovery subgroup and non-recovery subgroup based on whether patients had recovered.Serum Slit2 protein,prothrombin activity (PTA),total bilirubin (TBIL),and alanine transaminase (ALT)levels were detected and compared.Results A total of 157 patients (chronic hepatitis group,n =93;chronic severe hepatitis group,n=64)and 10 healthy volunteers were included in the study .Slit2 protein levels were significantly different among three groups(F =5.596,P =0.004),serum Slit2 protein levels in chronic hepatitis group and chronic severe hepatitis group were (4.90±1 .07)ng/mL and (3.09±1 .00)ng/mL respectively,both were higher than (2.10± 0.60)ng/mL in healthy control group (both P <0.05);serum Slit2 protein level in chronic severe hepatitis group was significantly lower than chronic hepatitis group (P <0.05).Serum Slit2 protein level in non-recovery subgroup of chronic severe hepatitis group was significantly lower than recovery subgroup ([1 .88±0.67]ng/mL vs [2.96± 1 .32]ng/mL,t=2.319,P =0.032).Serum Slit2 protein level in patients with chronic hepatitis B was positively correlated with PTA level(r=0.33,P <0.05),but negatively correlated with serum TBIL level (r =-0.46,P <0.05)and ALT level (r=-0.32,P <0.05).Conclusion Serum Slit2 protein level is an important index which can re-flect the prognosis of patients with chronic severe hepatitis,low serum Slit2 level suggests the poor clinical prognosis.

Objective To investigate the relationships between fasting plasma glucose (FPG) level in early pregnancy and gestational diabetes mellitus (GDM).Methods Data of 11 477 pregnant women who accepted prenatal care in Beijing Obstetrics and Gynecology Hospital from October 2011 to September 2012 were collected.FPG was tested during 8 to 12 weeks of pregnancy in all women and those with FPG＜7.00 mmol/L were recruited.Women accepted 75 g oral glucose tolerance test (OGTT) during 24 to 28 weeks of pregnancy.The GDM diagnostic criteria was with reference to the criteria of International Association of Diabetes and Pregnancy Study Group.Mann-Whitney U test was used to analyze the difference of early pregnancy FPG between normal pregnant women and GDM women.Receiver operating characteristic (ROC) curve was used to analyze the validity and applicability of using early pregnancy FPG in GDM diagnosis.Chi-square test was used to analyze the relationship between the FPG levels and GDM diagnosis.Results There were 1 535 (13.4％) women diagnosed as GDM in 24 to 28 weeks of pregnancy (the rest 9 942 normal cases were taken as the controls).The median FPG level of the GDM group was 4.89 mmol/L (4.62-5.15 mmol/L),which was higher than that of the controls [4.75 mmol/L(4.53-4.98 mmol/L)] (Z=-13.994,P=0.000).The maximum area under curve (AUC),which was used to predict GDM with early pregnancy FPG,was 0.599 (95％ CI:0.582-0.617).Taking FPG 4.88 mmol/L as the cutoff value,the sensitivity was 0.523 and the specificity was 0.645.While taking FPG 5.10 and 5.60 mmol/L as the cutoff value,the sensitivity was 0.334 and 0.068,and the specificity was 0.811 and 0.983,respectively.When the FPG level ≤ 4.09,-4.60,-5.10,-5.60,-6.10 and ≥ 6.10 mmol/L,the GDM diagnostic rate gradually increased [8.5％(23/212),9.9％(335/3 379),12.3％(719/5 858),20.7％(359/1 734),40.2％ (78/194) and 52.5％ (21/40)] (x2=300.523,P=0.000).GDM diagnostic rate in FPG ≤ 4.09,-4.60,-5.10 and-5.60 mmol/L group were lower than that in FPG ≥ 5.60 but ＜6.10 mmol/L group and ≥ 6.10 mmol/L group (x2 were 67.242,164.680,128.125,37.860,55.843,76.856,58.589 and 23.484,all P=0.000) ; GDM diagnostic rate in FPG ≤ 4.09,-4.60,-5.10 mmol/L group were lower than that in FPG ≥ 5.10 but ＜5.60 mmol/L group (x2 were 22.877,113.717 and 78.040,all P=0.000); GDM diagnostic rate in FPG ≥ 4.09 but ＜4.60 mmol/L group was lower than that in FPG ≥ 4.60 but ＜5.10 mmol/L group (x2=11.803,P=0.001).When using abnormal fasting and postprandial OGTT level as GDM diagnostic criteria,the ratio of GDM in early pregnancy FPG level ≥ 5.60 but ＜6.10 mmol/L group and FPG ≥ 6.10 mmol/L group were higher than that of the FPG level ＜5.60 mmol/L group [50.0％ (39/78) and 71.4％ (15/21) vs24.1％ (346/1 436),x2 were 12.456 and 21.443,all P＜0.003].Conclusions Early pregnancy FPG level is not proper to be used as an early diagnostic tool of GDM.However,when early pregnancy FPG level is equal to or greater than 5.60 mmol/L,the incidence of GDM in late pregnancy will increase significantly.

Tau is the most abundant microtubule-associated protein in the brain .If tau protein lost the normal function, the toxic effect should be showed and plays an important role in various central nervous system lesions .Hypoxic-ischemic encephalopathy ( HIE) is an important cause of mortality in the neonatal period and it is mainly characterized by neurological deficits such as cognitive limitations .However , the mechanism still needs further study , and the underlying re-lationship between tau protein and HIE lacks direct evidence .Some recent clinical study reported that tau protein expres-sion elevated in the serum of asphyxia children and had a high correlation with behavior deficient .In this review , we focus on 3 key points to provide new insights to understand the tau protein-related pathogenesis of HIE as followed:(1) tau pro-tein and its phosphorylation change during central nervous system development ;(2) comparison of tau protein expression in developing brain and adult brain under some neurological disorders;(3) potential pathological change of tau in HIE related pathological conditions , such as dysmyelination , inflammation response and glutamate metabolism .
