Professor LI Zhi-dao, according to acupoint selection of syndrome differentiation in TCM basic theory, concluded a new therapy, namely "tonifying three qi" that is mainly based on three acupoints in the Conception Vessel. This method is consisted of Danzhong (CV 17), Zhongwan (CV 12) and Qihai (CV 6) in the Conception Vessel, which could successively nourish clear qi, stomach qi and original qi. In clinic, according to the severity of symptoms of three qi, the acupoints are selected flexibly, which could respectively treat deficiency of heart-lung qi, deficiency of stomach-spleen qi and deficiency of original qi. Some examples are also given in the article.

ObjectiveTo explore the expression and clinical significance of Ras-related C3 botulinum toxin substrate 1 (Rac-1) protein and hypoxia-inducible factor 1α (HIF-1α) in breast cancer and their relationship with tumor stage, node metastasis status and hormone receptor status. MethodsImmunohistochemical method was used to detect the expression of Rac-1 and HIF-1α protein in 139 specimens of breast cancer,combined with their clinical pathological characteristics and hormone receptor status for statistical analysis.Results The expression of Rac-1 and HIF-1α in breast cancer tissue were 64.75 ％ and 65.47 ％,respectively.The levels were related with the stage of TNM and histological grade (P ＜ 0.05,P ＜ 0.01).There was no significant correlation between these two proteins'expression and the age of patient,primary pathological location, histologic type and menstruation status of breast cancer patients(P ＞ 0.05). The expression of Rac-1 and HIF-1α had no statistical significance between triple negative breast cancer(TNBC)and non-triple negative breast cancer (NTNBC) patients (x2 =1.1229,x2 =0.1786,P ＞ 0.05); The expression level of Rac-1 was positively correlated with HIF-1α in these breast cancer specimens (rs =0.414,P ＜ 0.01).ConclusionThe expression of Rac-1 is positively correlated with HIF-1α level in breast cancer.The relationship between Rac-1 and HIF-1α might be as a new important marker to estimate the invasion,metastasis extent and prognosis in breast cancer.Blocking the regulation between Rac-1 and HIF-1α might be a new treatment target in breast cancer.

OBJECTIVETo compare the efficacy between elongated needle therapy and regular needle therapy at Tiantu (CV 22) on the basis of xingnao kaiqiao (activiting brain and regaining consciousness) acupuncture therapy so as to explore the effective therapeutic method in treatment of dysphagia induced by bulbar palsy.

METHODSSeventy one cases of dysphagia induced by bulbar palsy were randomized into two groups. The xingnao kaiqiao acupuncture therapy was applied at Shuigou (GV 26), Neiguan (PC 6), Sanyinjiao (SP 6) and the others in the two groups. In the elongated needle therapy group, on the basis of xingnao kaiqiao acupuncture therapy, the elongated needle was used to puncture Tiantu (CV 22). In the regular needle therapy, the regular acupuncture technique was used at Tiantu (CV 22). In both groups, the treatment was given once a day in a week except Sunday and lasted for 4 weeks totally. Before and after treatment, the swallowing condition and the standardized swallowing assessment (SSA) were observed in the patients and the efficacy was compared between the two groups.

RESULTSThe total effective rate was 97.2% (35/36) in the elongated needle therapy group, which was better than 77.1% (27/35) in the regular needle therapy group (P<0.05). After treatment, SSA score was reduced significantly as compared with that before treatment in the two groups (both P<0.05). SSA score in the elongated needle therapy group was reduced much more apparently as compared with that in the regular needle therapy group after treatment (P<0.05).

CONCLUSIONOn the basis of the xingnao kaiqiao acupuncture therapy, the elongated needle therapy at Tiantu (CV 22) achieves the superior effect on bulbar palsy-induced dysphagia as compared with the regular acu- puncture at Tiantu (CV 22).

Twenty adult male rats, weighing 200～300 g were divided into 3 groups: (1) Six. animals were stimulated through two electrodes fixed on the tail to produce somatic pain.(2) Six animals were stimulated by increasing pressure in the stomach through an air balloon to cause visceral pain. And 8 animals served as control.All the animals were sacrificed and their neurohypophysis were fixed in 4％ glutaraldehyde and 1％ OsO_4 successively. Their section were cut with an LKB microtome and observed under H 500 electron microscope.The experimental results summarized as follows:1. The bodies of pituicytes under the pain stimulation were hypertrophied. The rough endoplasmic reticulum, polyribosomes and mitochondria were increased. The Golgi complex was well developed. There were numerous elliptical vesicles appearing in the cytoplasm of pituicytes.2. The number of large lipid masses was increased while the processes of pituicytes engulfed the degenerative neurosecretory terminal into them and the pituicyte digted it finally.3. Neurosecretory granules were decreased but the synaptic small vesicles were increased in the dilated parts of neurosecretory fibers after the pain stimulation.4. The continuous network of perivascular space and interstitial space between the dilated parts of neurosecretory fibers were widened.

Our experiments were designed to observe the cytological changes of the anterior lobes in rats pituitary at electron microscopic level after electric pain-stimulation. obvious changes were founded in the ACTH, GH and PRL cells and slight changes in the FSH and TSH cells. However, the LH cells remained to resemble the normal cells. In the experiment group of the somatic painful stimulation the results were as follows: The ACTH cells were irregularly shaped, with extended thin and long plasmatic processes which interdigitated with GH cells. The processes filled with secretory granules. Some of the Secretory granules aligning along the plasmatic membrane showed pale density. The flat cisternae of rough endoplasmic reticulum (RER) appeared to be slightly dilated. The sizes of the bodies of GH and PRL cells increased. In the GH cells there were numera media cisternae in RER, their Golgi complex was well developed, and the secretory granules were distributed to the periphery of the cell bodies. All these phenomenous showed the secretory activity of these cells was enhanced. The PRL cells contained well developed Golgi complex and abundant RER. In the experiment group of the visceral painful stimulation the results were as follows: There were more striking changes of parenchymal cells of anterior lobes in rats pituitary than those of the experimental group of the somatic painful stimulation. The cell bodies of ACTH, GH and PRL cells showed hypertrophy, the nucleus enlarged and nucleolus were relatively prominent. The dense granules decreased in number and the pale or empty visicles almost situated near the plasmic membrane in ACTH cells. In the GH cells large vacuoles were distributed throughout the cytoplasma. The number and density of the secretory granules decreased. In PRL cells the Golgi complex were extended, the dictyosomes increased, in addition, RER, polyribosomes and mitochandria were more aboundant than that in these normal cells. These cytological changes suggested secretory and synthetic activity of these cells were enhanced. At last, pain in relation to several hormones such as ?-endorphin, ?-LPH, ACTH and ?-MSH etc. were discussed by the author.

The purpose of this research work is to study the influence of experimentally produced pain on the uhrastructural changes of the nerve endings of the neurosecretory fibers from hypothalamus to neurohypophysis.Twenty adult male rats, weighing 200～300 g were divided into 3 groups: (1) Six animals were stimulated through two electrodes fixed on the tail to produce somatic pain. (2) Six animals were stimulated by increasing pressure in the stomach through an air balloon to cause visceral pain. And 8 animals served as control.All the animals were sacrificed and their neurohypophysis were fixed in 40％ glutaraldehyde and 1％ OsO_4 successively. Sections were cut with an LKB microtome and observed under H500 electron microscope.The following conclusions were drawn from the observed results:1. The neurosecretory granules in the fibers from hypothalamus to neurohypophysis grew up to maturity by increasing in size gradually as they passing down from hypothalamus to neurohypophysis.2. Basing on the morphological exhibition of the neurosecretory granules, we get the impression that the neurosecretion might be released either by molecular dispersion or by exocytosis.3. There were a great number of discrete smooth vesicles grouped in cluster in the dilated parts of neurosecretory fibers. These vesicles had been called as "synaptic" or "synaptoid" vesicles. They might be really synaptic vesicles and containing acetylcholine. Other vesicles with irregular profile and varying in size, collapsing vesicles and vacuoles might be the residues of the neurosecretory granules after discharging their content.4. Many synaptic vesicles were concentrated at the axolemma of the dilated parts of neurosecretory fibers and the membranes were thickened and leaving a synaptic cleft.5. In the exprimental groups after pain stimulation the neurosecretory granules decreased in number and the synaptoid vesicles increased in number and the neurosecretory granules showed a wide pale halo. The number of irregular vesicles and ghost of granules were increased. This phenomenon might show that the excretion of neurosecretory material and neurotransmitters was enhanced.6. Neurohemal zones were the barrier for the neurosecretory material entering into blood. Acetylcholine, endogenous opiatelike substances and gamma-aminobutyric acid (GABA) might play a control role for neurosecretion at this site.7. This experimental results supported the action mechanism of endogenous opaitelike substance and morphine could produce an important role directly in neurohypophysis.
