OBJECTIVE:To investigate the effects of tiotropium bromide assisted with bronchoalveolar lavage (BAL) on short-term efficacy,quality of life and re-hospitalization rate of patients with bronchiectasis complicated with lung infection. METH-ODS:A total of 140 patients with bronchiectasis complicated with lung infection selected from our hospital during Oct. 2013-Dec. 2015 were divided into control group and observation group by lottery,with 70 cases in each group. Based on intervention therapy, control group received BAL. Observation group was additionally given Tiotropium bromide powder inhalation 18 μg ,once a day before going to bed,on the basis of control group. Both groups were treated for 4 weeks. Clinical efficacy was compared between 2 group;pulmonary ventilation function indexes,blood gas analysis indexes,BODE index scores and QLI scores before and after treatment,re-hospitalization rate and the occurrence of ADR were also compared between 2 groups. RESULTS:The total response rate of observation group was 91.43%,which was significantly higher than that of control group(78.57%),with statistical signif-icance (P<0.05). Before treatment,there was no statistical significance in pulmonary ventilation function indexes,blood gas analysis indexes,BOED index scores or QLI scores between 2 groups(P>0.05). After treatment,FVC,FEV1,FEV1%,p(O2) and QLI score of 2 groups were increased significantly,while p(CO2)and BODE index scores were decreased significantly,com-pared to before treatment;all indexes of the observation group was significantly better than the control group,with statistical sig-nificance (P<0.05). The re-hospitalization rate of observation group 3,6 months after treatment was significantly lower thanthat of control group,with statistical significance(P<0.05). No ADR was found in 2 groups. CONCLUSIONS:For patients with bronchiectasis complicated with lung infection,tiotropium bromide assisted with BAL can effectively relieve the clinical symp-toms and signs,improve lung ventilation function and the quality of daily life and can be helpful to reduce the risk of re-hospital-ization with good safety.

Pancreatic adenosquamous carcinoma is a rare exocrine pancreatic cancer,and surgical treatment is the only promising method in survival time extension and life quality enhancement.In July 2013,1 patient with pancreatic adenosquamous carcinoma and sarcomatoid change was admitted to the Shaoxing People's Hospital.A cauda pancreatis cystic nidus was detected by computed tomography 1 year ago,and no any other clinical symptoms were detected.The left upper quadrant of the patient was glutted and unwell,and the levels of CA19-9 and CA125 were 3 630 kU/L and 645 kU/L,respectively.The results of computed tomography and magnetic resonance imaging showed that a huge cystic and solid tumor was located between the cauda pancreatis,the stomach and the spleen;the tumor was mainly cystic and rooted in the tail of the pancreas;the spleen,stomach and surrounding tissues were infiltrated by the tumor.The results of postoperative pathological examination showed that the tumor was pancreatic adenocarcinoma with squamous epithelial differentiation and sarcomatoid change;the invasive squamous carcinoma dominated stomach wall,and the sarcomatoid change dominated spleen and lymph nodes with partial squamous epithelial differentiation and surrounding lymph nodes metastases.Although the surgical resection was complete and the postoperative thymosin injection and traditional Chinese medicine were implemented,tumor recurred at postoperative month 5,and the patient was dead due to cachexia and pernicious anemia at postoperative month 8.The prognosis of patients with pancreatic adenosquamous carcinoma is poor,early detection and surgery are key points for curative effect enhancement.

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.

Pain just tolerable was caused intermittently by electric stimulation on rat's tail or by distented baloon in stomach for 30 min. The changes of intermediate lobe are summarized as follows: (1) The cell body, nucleus or nucleolus was hypertrophied. The number of rough endoplasmic reticulum, particularly of its vesicular cisternae was increased. Golgi complex enlarged. The ribosome multiplied. All of these change indicated that the activity of cells was increased and the rate of synthesis enhanced. (2) Both the secretory granules shifted to the periphery of cell body and some of them showed pale density. These changes were interpreted as increase of seretory activity. (3) The mitochondria became enlarged and the crsitae in them were changed into tubular form. This suggested an acceleration of cell metabolism, which might provide a large amount of energy. (4) There was no degenerative change. (5) The cytological changes caused by visceral pain were simillar with, but more striking than, those caused by somatic pain. (6) The secretions were increased, among which ?-endorphin and ACTH etc were known to be closely related to analgesia.

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.

Objective: To investigate the anti-tumor effect of Glycyrrhiza flavonoids(GF) and its immunological mechanism.Methods: Mice bearing sarcoma 180(S180) were randomized into 3 GF-treated groups and one control group.The mice in GF-treated groups were perfused with GF.Leukocyte and lymphocyte count were taken by the blood cell analyzer.Flow cytometry was performed to detect the percentages of the T cell subsets.Results: Treatment of GF resulted in the tumor inhibition rates of 52.3%(high dose group).Blood total leukocyte and lymphocyte count in GF treated groups were all higher than that in the control group,and there was the most significant increase of the number of immune cells in the high dose GF group(P

Objective To study the relationship between chromosomal abnormality and Y chromosome microdeletions and male infertility. Methods Lymphocytes were cultured from peripheral blood of 1975 male infertility patients and stained with Giemsa. The chromosomes were analyzed under microscope. Y chromosome specific sequence tags (STS) were selected, then the Y chromosome microdeletions in AZF regions were screened by polymerase chain reaction (PCR) in azoospermia and oligozoospermia patients. Results There were 305 cases of detected chromosomal abnormalities (15.44%) in the 1975 cases. There were 101 cases (5.11 %) with autosome abnormalities which clinically manifested as oligozoospermia and teratospermia. There were 204 cases (10. 33%) of sexual chromosome abnormalities and the patients were mainly characterized with Klinefelter's syndrome. Y chromosome microdeletions were detected in 109 (14.97 %) of the 728 cases of azoospermia or oligozoospermia. The most common microdeletion of Y chromosome was AZFc (62.39%) and these patients were characterized with azoospermia and oligozoospermia. Five patients (4. 59%) who suffered Y chromosome microdeletion in AZFa region and AZFb region were characterized with azoospermia. Fifteen cases (13.76%) with microdeletion in AZFb region and AZFc region were mainly characterized with azoospermia. There were 6 cases (5. 50 % ) of microdeletion in AZFa, AZFb and AZFc regions,these patients were all characterized with azoospermia. Conclusions Both Chromosome abnormalities and Y chromosome microdeletions are important causes for male infertility.

Objective To apply the model for end-stage liver disease(MELD)and the ChildTurcotte-Pugh(CTP)in predicting short-term prognosis of patients with severe chronic hepatitis B,and to evaluate their clinical value.Methods Data of 115 patients with severe chronic hepatitis B were retrospectively analyzed and all patients were divided into survival gnmp and fatal group by survival status at 3rd month of the treatment.The scores of MELD and CTP were obtained.The accuracies of MELD and CTP were evaluated by the receiver operating characteristic(ROC)curve.The difference between two systems was analyzed by Kaplan-Meier survival curve.Results MELD and CTP scores in fatal group were significantly higher than those in the survival group(t=4.891 and 3.949,P＜0.05),and two systems were significantly correlated(γ=0.500,P=0.000).MELD and CTP scores were good for predicting the fatality rate of patients with severe chronic hepatitis B within 3 months(C-statistic:0.765 and 0.834,respectively),and there was no significant difference between the two systems(Z=1.516,P＞0.05).Patients with CTP＜10.5 or MELD＜27.5 had longer survival time(Z:17.88 and 25.28,P=0.000)and higher survival rates(χ2=16.88 and 31.59.P=0.000)than those with CTP＞10.5 or MELD＞27.5.Conclusion MELD and CTP scores have similar predictive valHe for short-term prognosis of patients with severe chronic hepatitis B.and clinical data should be contained to better predict the short-term prognosis.
