Objective:To improve the accuracy of the rotary manipulations of the neck in the treatment of neck pain, according to subjective and objective clinical findings. Methods: Two groups of 60 outpatients diagnosed with neck pain were suited to the manipulation and each group was 30 cases. The diagnosis of neck pain was made with conventional clinical evaluation, including history, palpation examinations, CT scan and X-ray. Group A received a manipulation of obliquely pulling the neck. While group B received manipulation of pulling the rotated and located neck. Subjects received a maximum of 10 treatments over a 3-week treatment period. Both treatment groups were assessed with subjective (cervicodynia, neck discomfort, upper limb numbness, vertigo and tinnitus) and objective (cracking sounds). The cracking sounds during two of the manipu1ations were recorded by a microphone positioned at both sides of the neck. The sounds were compared in patients of two groups. Statistical analysis was conducted with a one-factor within-subjects analysis of variance tests and descriptive statistic. Results: Analysis of the subjective indicated that the cases with upper limb numbness were reduced from 12 to 6 in group 2, while the cases with vertigo and tinnitus were reduced from 13 to 4 in group 1. Analysis of the objective indicated two kinds of neck rotary manipulations act not only on the rotary-side facet joints, but on the opposite to the rotary side on1y in a few cases. The results showed that manipulation of pulling the rotated and located neck has a small action range and centralized action points, while manipulation of obliquely pulling the neck has many action segments and discentra1ized action points. Conclusion: It was concluded that the rotary manipu1ations act mainly on the rotary side, not on the opposite, and that manipulation of obliquely pulling the neck has a wider action range and a better therapeutic effect on cervical upper-segment lesions, while manipulation of pulling the rotated and located neck has a limited action range and is suitable for cervical lower-segment lesions. There were some relations between the joint sounds during the manipulation and clinical curative effect.

Sleep plays an important role in the modulation of endocrine function and energy metabolism;hormone levels are markedly different during a sleepless night compared with a night of normal sleep.Sleep deprivation may change the levels of cortisol,growth hormone(GH)and thyrotropin(TSH)at night.In addition,sleep curtailment disturbs the balance of anorexi- genic(leptin)and orexigenic(ghrelin)factors,and does harmful to glucose tolerance.

This study evaluated the efficacy and safety of "J"-shaped uterine incision for caesarean section for patients diagnosed with placenta previa. A total of 55 consecutive cases of placenta previa treated in Union Hospital were retrospectively analyzed over a period of two years and 10 months. The subjects were divided into two groups with respect to the uterine incision. Twenty-four pregnant women with placenta previa who were indicated for caesarean section underwent the procedure using a new "J"-shaped uterine incision and 31 pregnant women with placenta previa received caesarean section that used the traditional transverse incision. The two groups were compared in terms of operation time, estimated blood loss, infant expulsion time, exhaust time and postoperative recovery. Meanwhile, comparison was also made in neonatal clinical data between the two groups. Compared with the "J"-shaped incision group, the traditional incision group had a lower Apgar scores (P<0.05). However, there existed no statistically significant differences in the overall time of operation and postoperative period of breaking wind (P>0.05). It is concluded that, with caesarean section for placenta previa patients, the "J"-shaped uterine incision significantly decreases intraoperative blood loss and facilitates the fetal delivery.

The underlying effect of different concentrations of neogenin on proliferation, apoptosis and the related proliferative factors in human trophoblasts was explored in order to understand the function of neogenin during placentation. TEV-1 cell line was cultured and the expression of netrin-1 was detected by using indirect cellular immunofluorescence. Exponentially growing TEV-1 cells were treated by different concentrations of neogenin (0, 1, 5, 10, 50 ng/mL) for 24 h. Cell viability was measured by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. TEV-1 cell apoptosis was assessed by flow cytometry (FCM). The expression of netrin-1 mRNA and protein in TEV-1 cells was examined by using real-time PCR and Western blot, respectively. It was found that immunoreactivity for netrin-1 was observed in cytoplasm of the trophoblasts. Immediately after treatment with different concentrations of neogenin for 24 h, the netrin-1 expression began to increase. Real-time PCR revealed that the expression level of netrin-1 mRNA was 37.59+/-10.25 times higher than control group when TEV-1 cells were exposed to 50 ng/mL neogenin (P<0.01), and the same tendency was seen by using Western blot. MTT results showed that proliferation of TEV-1 cells was independent of neogenin. Meanwhile, apoptosis was significantly increased to (22.15+/-6.15)% at 50 ng/mL neogenin and (6.55+/-0.25)% without neogenin (P<0.01). It is suggested that neogenin regulates proliferation and apoptosis of TEV-1 cells. And it can enhance the ability of TEV-1 cells to express netrin-1 in a dose-dependent manner. Neogenin may play an important biological role in the normal human pregnancy and contribute to the physiological pregnancy process.

After the factors that influence the selection of words were analyzed according to the problems in selec-tion of words for co-word analysis, a hypothesis for how to select the word sets with its verification analysis was pro-posed, the method for selecting words was thus decided according to the word frequency-covered literature area and the number of high frequency words. However, its practical use in large data sets needs to be further improved.
