OBJECTIVE: Adopting methods of cell culture to explore the effects and mechanisms of Jianpi Bushen Huoxue Prescription (JPBSHXP), a traditional Chinese compound herbal medicine for strengthening spleen, reinforcing kidney and activating blood circulation, in inhibiting hematopoietic cells apoptosis in a mouse model of aplastic anemia (AA). METHODS: Blood serum of AA mice was made from an AA mouse model. Blood serums containing different traditional Chinese compound herbal medicine were made from rats after intragastric administration of JPBSHXP and its related decoctions, respectively. Bone marrow cells of normal mice were incubated by these blood serums for 24 hours, respectively. The apoptosis of the bone marrow cells were assayed by flow cytometry and transmission electron microscopy (TEM). RESULTS: It was indicated that the bone marrow cells of normal mice incubated with blood serum of AA mice displayed typical apoptosis. The apoptosis rates of bone marrow cells of the AA mice incubated by blood serum containing different traditional Chinese herbal medicine were decreased. The effect of Bushen (reinforcing kidey) Recipe was better than Jianpi (strengthening spleen) Recipe and Huoxue (activating blood circulation) Recipe, while the effect of JPBSHXP was the best. TEM results showed that the effect of Bushen Recipe was better than that of the Jianpi Recipe and the Huoxue Recipe, while the effect of JPBSHXP was the best. CONCLUSION: JPBSHXP and its related decoctions can significantly decrease the apoptosis rate of bone marrow mononuclear cells of the AA mice. It is inferred that JPBSHXP can promote bone marrow hematogenesis.

Objective:To evaluate the efficacy and safety of acupuncture-moxibustion in the treatment of cerebral palsy-related speech impairment.Methods:A systematic literature search of 7 electronic databases was conducted between January 7,2000 and January 12,2021 to find randomized controlled trials(RCTs)examining the benefits of acupuncture-moxibustion combined with rehabilitation training to cerebral palsy-induced speech impairment.The included trials'quality was assessed using the Cochrane Reviewers'Handbook as a guide,and statistical analysis was carried out using the RevMan 5.3 software.Results:A total of 17 RCTs with 1238 subjects were finally recruited and analyzed.When acupuncture-moxibustion was combined with rehabilitation training,the results showed a considerable improvement in speech impairment compared with the rehabilitation training alone.The most commonly used points for the treatment of speech disorders are Baihui(GV20),Speech Area,Zhisanzhen[Shenting(GV24)and bilateral Benshen(GB13)],Niesanzhen[2 Cun above the ear tip as the first point,with 1.0 Cun anterior and posterior to the current point as the second and third points],and Sishenzhen[1.5 Cun anterior,posterior,and bilateral to Baihui(GV20)].Conclusion:Acupuncture-moxibustion has a stronger effect on children's development of receptive and expressive language,as well as the developmental quotient.Acupuncture-moxibustion in combination with rehabilitation training is not only more successful than the control treatment,but also safer and more dependable.Baihui(GV20),Speech Area,Zhisanzhen,Niesanzhen,and Sishenzhen are the most widely used points for speech impediment.

Objective:To observe the efficacy of cytokine-induced killer (CIK) cells on patients with advanced lung cancer. Methods:A total of 90 patients with advanced lung cancer were identified from January 2011 to December 2013. CIK therapy was given to 41 pa-tients in the observation group, whereas the other 49 patients in the control group received the best support treatments without che-motherapy or radiotherapy within one month of inclusion. Following up was conducted for the patients in the two groups, and KPS scores, median survival, and adverse reactions compared. Results:The KPS score in the observation group was higher than that of the control group after treatment (P=0.034). The median survival period of the observation group was eight months, which was one month longer than that of the control group (P=0.044). Major adverse reactions included fever, joint pain, and insomnia, which were recorded 51.22%, 36.58%, and 29.27%of occurrence, respectively. Conclusion:CIK cell therapy improved the quality of life and pro-longed the survival of advanced lung cancer patients with tolerable adverse reactions.

OBJECTIVE: To observe the clinical effect of Shengxueling Granule (SXLG) in treating idiopathic thrombocytopenic purpura (ITP), and to study its possible mechanism. METHODS: Eighty-six cases of ITP were divided into two groups randomly. Fifty-six cases in the treatment group were treated with SXLG, a traditional Chinese medicine, and 30 cases administered with Western medicine (prednisone) were taken as control. Patients in each group took drugs for three months and were under follow-up observation. RESULTS: In SXLG-treated group, the total effective rate in 3 months was 85.71%, similar to 83.33% in prednisone-treated group (P>0.05), while the total effective rate in 6 months in the SXLG-treated group was 91.07%, higher than 53.33% of the prednisone-treated group (P<0.01), and no obvious side-effects were observed. The patients' bleeding was alleviated or stopped, and their general condition was improved. And the blood platelet count (BPC) was increased, the platelet associated immunoglobulin (PAIg) and interleukin-4 (IL-4) were markedly dropped, the level of natural killer cells activity (NKCA) increased, and the rate of T lymphocyte subsets gradually returned to normal level. Megakaryocytes tended toward maturation on bone marrow smear after SXLG treatment. All differences above were statistically significant. CONCLUSION: SXLG is an effective and safe medicine for ITP. It can regulate the cellular immunity, inhibit the platelet antibody to reduce the destruction of the platelet and to increase the number of platelet, promote the differentiation and maturation of megakaryocyte, facilitate the production and release of platelet, lower the fragility of capillary, and prevent the hemorrhagic tendency.

Objective To summarize the methods of diagnosing and treating solid-pseudopapillary neoplasm of pancreas SPN so as to provide reference for its early clinical diagnosis.Methods We collected the clinical data of 62 patients with pathologically confirmed diagnosis of SPN treated in the First Affiliated Hospital of Xi'an Jiaotong University between Feb.2004 and Sep.2014.Then we retroactively analyzed and summarized the clinical characteristics,diagnosis and treatment of the disease.Results Among the 62 patients,55 were female and 7 were male;the mean age was (31.58±12.67) years old.The clinical features showed no specificity and the tumor was mostly detected upon physical check-up.The tumor was seen to be located mostly in the body and tail of the pancreas,and the average maximum diameter was (7.81±3.54)cm.We did not find obvious abnormality in routine pre-operative blood test results or liver and kidney functions.The imageological examination indicated tumor occupation in the pancreas.All the patients underwent surgical resection with no complications or death and had a good recovery after operation.Pathological diagnosis after operation was SPN without metastasis in lymph modes.Until the last time we followed up all the patients,we found relapse in two patients (3.2％).Conclusion SPN is a tumor that tends to affect young and middle-aged females.The malignancy grade of SPN is low,and patients with this disease show no specificity in clinical manifestation.The imageological examination is of vital importance in diagnosing SPN and surgical resection is an effective way to treat SPN.

Objective To study the correlations between the genetic polymorphism of brain-derived neurotrophic factor (BDNF) and the postpartum depression (PPD) in cesarean section parturient. Methods Three hundred and sixty parturients, who underwent cesarean section under spinal anesthesia from Feb. 2014 to Feb. 2015 in Third Xiangya Hospital of Central South University or Hunan Maternal and Child Health Hospital, were selected as subjects. The general information of parturients was recorded and Edinburgh Postnatal Depression Scale (EPDS) was used to evaluate the depression condition of parturients at the prenatal 1 day and the 42th day postpartum, and with a cut-off point of 12/13 for identifying PPD. The genotypes of BDNF gene locus G712A, rs56164415, rs11030100, rs11030101 and rs6265 were measured by Sequenom? Mass Array SNP. Finally, the correlations of PPD to different genotypes and general information of parturients were statistically analyzed. Results The incidence of PPD among the selected subjects was 7.2%. Pregnancy mental stress, poor pregnancy mood, perinatal elevated monocyte count, prenatal depression mood and BDNF gene locus rs6265 mutation all could affect the incidence of PPD in cesarean section parturients (P<0.05). No statistically significant difference existed between BDNF gene G712A, rs11030101, rs11030100 and rs56164415 locus mutation and PPD (P>0.05), and their haploid forms were not related to PPD also. Conclusion BDNF rs6265CC genotype, pregnancy mental stress, poor pregnancy mood, perinatal elevated monocyte count and prenatal depression mood are the risk factors for postpartum depression.
