China Journal of Chinese Materia Medica 2014;39(10):1937-1940
Polycystic ovary syndrome (PCOS) is one of the most popular diseases in obstetrics and gynecology research at internal and abroad at present, traditional Chinese medicine(TCM)in the clinical treatment of the disease have the advantage. Clinical epidemiological study of descriptive research method this research adopts investigation, observation of TCM syndromes and improper diet through 401 cases in Jiangsu Province confirmed PCOS patients, to explore the relationship between TCM syndrome type distribution and improper diet factors, and to provide the clinical basis for further etiology of this disease research. TCM syndrome type distribution of the disease is kidney deficiency, phlegm stagnation syndrome, qi stagnation and blood stasis syndrome, syndrome of dampness heat of liver channel and is composed of 4 basic syndromes and formed complex syndrome, and the composite and syndrome type (60.85%); combined with the analysis of traditional Chinese medicine dialectical, Pure empirical syndrome this disease (46.88%), followed by the actual card (45.39%), pure deficiency is rare. Improper diet factors associated with the disease, in which improper diet with different TCM syndrome type distribution significantly related. Stagnation of phlegm dampness syndrome is the main syndrome of the disease type, improper diet factors and every syndrome PCOS type distribution is as follows: the partial eclipse fatness greasy with basic syndromes of phlegm dampness stagnation of kidney deficiency syndrome, the nephrasthenia syndrome is less; eating spicy stimulation by basic syndromes of stagnation of Qi and blood stasis; eating cold people the basic certificate type of qi stagnation and blood stasis; The diet of patients are more prone to stagnation of phlegm dampness syndrome.

BACKGROUND: Observation and comparison about space-occupying lesions due to herniated nucleus pulposus, as well as nerve root compression in lumbosacral disc herniation and manipulative therapy are easily available; however, there is still lack of related quantitative research regarding the internal pressure in herniated nucleus pulposus.OBJECTIVE: To observe the influence of the internal pressure in herniated nucleus pulposus on nerve root compression in patients with lumbosacral disc herniation.DESIGN: Case control study.SETTING: Bone Setting Therapeutic Center, the Air Force General Hospital of Chinese PLA.PARTICIPANTS: Totally 30 patients with lumbosacral disc herniation received operation in the Orthopedic Department of the Air Force General Hospital between October 2002 and December 2003; meanwhile, 15 patients with lumbosacral disc herniation received manipulative therapy in the Bone Setting Therapeutic Center of the same hospital.ing positive group and negative group according to the results of straight leg raising test. The pressure in herniated nucleus pulposus was detected during operation, and the straight leg raising height was also recorded beThe size of intervertebral disk herniated nucleus was presented by the maximum vertical distance from the intervertebral disk herniating apex to the posterior edge of vertebra on CT and/or MRI transverse section.raising height.RESULTS:Totally 30 patients received operative treatment whereas 15The pressure in lumbosacral disc herniated nucleus andthe size of herniated nucleus pulposus: as for patients who received operation, the pressure in herniated nucleus pulposus was obviously higher in positive group than in negative group [(2.119±0.753), (0.483±0.420) kPa, P < 0.01]. However,the size of herniated nucleus pulposus was not significantly different between positive group and negative group [(4.688±1.991), (4.857±2.033) mm,nipulative therapy, their straight leg raising height was obviously increased compared to that before operation [(54.000±16.388)°, (72.668±15.338)°,P < 0.01], but the size of herniated nucleus pulposus was proved not obviously changed by CT or MRI examination after manipulative therapy (P > 0.05).cleus pulposus on nerve root is related to the iuternal pressure of herniated nucleus pulposus; higher internal pressure in herniated nucleus pulposus would limit straight leg raising height while lower internal pressure has less effect. However, the compression of herniated nucleus pulposus on nerve root has no obvious relationship with the size of herniated nucleus compression by reducing the internal pressure in herniated nucleus pulposus, which may not only depend on changing the space-occupying of herniated nucleus pulposus.

AlM: To evaluate the application of phacoemulsification of different nucleus density using ozil and traditional mode.METHODS: A total of 89 eyes (72 patients ) ( visual acuity was of 0. 6 and above after 1mo follow - up) of different nucleus density level (LOCS Ⅱ criteria grade Ⅲ 46 eyes, grade Ⅳ and more 43 eyes ) were randomly assigned into 2 groups: ozil group (group A), grade Ⅲ 22 eyes (torsional energy 80% lP on);grade Ⅳ and more 17 eyes (torsional energy 100% lP on); Traditional mode group(group B), grade Ⅲ 24 eyes (energy 50% ), grade Ⅳ and more 26 eyes (energy 60% ~ 70% ) . All surgeries were performed by the same experienced surgeon,who use the chop to split the nucleus in the application of phacoemulsification. lntraoperative parameters were total equivalent pawer ( TEP ), cumulative dissipated energy ( CDE ) and effective phaco time ( EPT ) and surgical complications. The effectiveness of the two modes in dealing with hard - core cataract phacoemulsification were compared.RESULTS: GradeⅢ nucleus dealing: TEP of ozil group was significantly higher than that of the traditional mode group [(24.58±7.78)% vs (13.84±1.97) %]and EPT of ozil group was significantly lower than that of the traditional mode group (50. 59±14. 73 s vs 60. 19±9. 04 s, P<0. 05). CDE showed no difference between two groups [(13.12±6.03)% vs (13.38±2.85)]. Grade Ⅳ and more nucleus dealing: CDE [( 34. 10 ± 13. 48 )%] and EPT (104. 64±32. 4s) of the ozil group was higher than CDE [(30. 31 ± 13. 48)%] and EPT (93. 01 ± 41. 01s) of the traditional mode group, but there were no difference between two groups. Obstacles in the needle of phacoemulsification surgery: ozil group 4/17, traditional mode group 2/26 (χ2=2. 16, P=0. 14).CONCLUSlON: Bothozil and traditional mode can deal with all kinds of nucleus effectively and safely. Ozil mode is more efficacy and quick deal in gradeⅢnucleus. With the increase of nucleus hardness, the traditional mode still have the advantage of high efficiency and no obstacle to dealing patients with grade Ⅳ and more nucleus. Choose according to different nuclear hardness ultrasonic model can improve the operation efficiency and security.
