BACKGROUND: Bone marrow inhibition is a predominant side effect caused by the drugs for anti-tumor.OBJECTIVE: To observe the intervention effect of traditional Chinese medicine qiongyugao on bone marrow inhibition induced by chemotherapy in experimental mice with pulmonary adenocarcinoma.DESIGN: Randomized controlled trial.SETTING: Medical College of Jinan University.MATERIALS: The experiment was completed in the Central Laboratory of Medical College of Jinan University from March to October in 2001. Fortyeight healthy, aged 6 to 8 weeks C57/BL mice were involved.METHODS: The mouse model with pulmonary adenocareinoma was made with the method of inoculability of cancer cell, and then the models were group: On the following day of inoculation, 0.2 mL normal saline was used by gavage, and normal saline was injected intraperitoneally at the dosage of amine 20 mg was diluted into 0.2 g/L with normal saline, and performed intraperitoneal injection at the dosage of 5 μL/g, once per day, and 0.2 mL platinum diamine was used as in chemotherapy group and 0.2 mL qiongyugao was administered by gavage at the same time once per day. Peripheral erythrocyte, leukocyte and blood platelet, and karyota in bone marrow counting were detected on the 21 days after administration.MAIN OUTCOME MEASURES: Peripheral erythrocyte, leukocyte and blood platelet, and karyota in bone marrow counting of the mice in each group.RESULTS: Eleven mice failing to have tumor in tumor assessment were excluded from the sample, including 3 in the control group, 4 in the chemotherapy and 4 in the combination group. During the experiment,there were 2 mice dying in each group of the control group and chemotherapy group. Totally 11 mice in the control group, 10 in the chemotherapy group and 11 in the combination group entered the result analysis. Erythrocyte, leukocyte and blood platelets in the combination group and control group were all significantly higher than those in the chemotherapy group [erythrocyte: (8.54 ±0.81 ), (8.65 ±0.77), (4.56 ±1.00) ×1012 L -1;leukocyte:(9.04 ±0.60), (9.14 ±0.71), (3.31 ±0.96) ×109 L -1;blood platelets:(949.09±111.31 ), (955.54±87.13), (399.30±131.36)× 109 L-1 ,P ＜ 0.01]. The number of karyota in bone marrow in the chemotherapy group was significantly lower than those in the combination group and control group [(5.30±1.12),(10.51±1.15),(14.36±1.02)]×106,P ＜ 0.01); while the number of karyota in the control group was higher than that in the combination group (P ＜ 0.05).CONCLUSION: Qiongyugao can enhance the counting of erythrocyte,leucocyte, blood platelets of peripheral blood and karyota in bone marrow after chemotherapy in mice with pulmonary carcinoma, improve the inhibition of bone marrow induced by chemotherapy, but can not reverse it completely.

Objective:To study the change of bifrontal metabolite concentration in patients with mild cognitive impairment (MCI) and its relationship with substantia alba demyelination using magnetic resonance spectroscopy (MRS) combined with linear combination of model (LCModel) quantitative technique.Methods:From May 2016 to December 2018, 25 patients with MCI (group A; 12 males, 13 females, age (60.5±5.2) years) and 15 healthy control subjects (group B; 6 males, 9 females, age (59.5±3.5) years) in the Second Affiliated Hospital of Shantou University Medical College were prospectively enrolled. The MCI patients were classified into 2 subgroups according to MRI results: group A1 with substantia alba demyelination (7 males, 4 females, age (62.1±3.9) years) and group A2 without substantia alba demyelination (5 males, 9 females, age (59.2±5.8) years). Software LCModel was used to quantitatively analyze the MRS original data and measure the absolute concentration of N-acetylaspartate compound (NAA), creatine compound (Cr), choline-containing compound (Cho), myoinositol (mI) and ratios of NAA/Cr, Cho/Cr, mI/Cr, NAA/mI in bilateral frontal lobe. Independent-sample t test was used to analyze the inter-group differences of the above parameters, while Pearson correlation analysis was performed to analyze correlations between the above parameters and cognitive function scores. Results:Compared with group B, group A had higher mI of both left and right frontal lobes (left: (5.19±1.28) vs (4.32±0.83), right: (4.87±1.11) vs (3.85±0.98); t values: 2.34, 2.93, both P<0.05); the mI/Cr of right frontal lobe in group A was also higher (1.19±0.31 vs 0.98±0.25; t=2.21, P<0.05), while the NAA/mI of right frontal lobe was lower (1.37±0.34 vs 1.78±0.47; t=-3.16, P<0.01). Differences of other parameters between group A and group B, and those between group A1 and group A2 were not significantly different ( t values: -1.70 to 1.35, all P>0.05). The mI of right frontal lobe was negatively correlated with Montreal Cognitive Assessment (MoCA) score and Mini-Mental State Examination (MMSE) score( r values: -0.35, -0.38, both P<0.05), on the contrary, NAA/mI of right frontal lobe was positively correlated with the cognitive function scores ( r values: 0.43, 0.40, both P<0.05). Conclusion:MCI may be related to the loss or dysfunction of neurons in the right frontal lobe, and MRS can provide theoretical basis for early recognition of MCI to some extent.

Objective To detect any association between chemosensitivity of tumor in vitro and clinico-pathological characteristics of patients with breast cancer, such as age, pathological type, pathological grade, as well as local lymph nodal status. Methods Sixty patients with breast cancer were tested with tissue culture-end point staining-computer image analysis (TECIA) after resection of the primary lesion or biopsy. Their chemosensitivity to seven common anticancer drugs were evaluated, which were fluorouracil (5-Fu), vinorelbine(NVB), cisplatin(DDP), paclitaxel(TAX), docetaxel(TAT), doxorubicin(ADM) and epirubicin(EADM). Results 31.67% of the total 60 specimens were resistant to all of 7 drugs. The sensitive rate of the tissues to a specific drugs was 60.00 % (36/60) for EADM, 54.00 %(32/60) for NVB, 36.00 %(22/60) for DDP or TAT, 30.00 %(18/60) for TAX, 26.00 %(16/60) for 5-Fu and 16.00 %(10/60) for ADM in turn. The sensitive rate of invasive carcinoma group was higher than non-invasive carcinoma group (74.47 % vs 46.15 %, P< 0.05), and grade Ⅲ group higher than grade Ⅰ or grade Ⅱ group (90.91% vs 54.55 %, 90.91% vs 55.56%, P<0.01). The differences of sensitive rates among three different age groups and between two groups with/ without lymph nodal metastasis were not significant statistically (P > 0.05). Conclusion The total sensentive rate of breast cancer might be relatively high to EADM, NVB and TAT, and TECIA could be an important reference for clinical individual chemotherapy.

Objective:In this study, a simple and easy diagnostic index of sarcopenia based on computed tomography (CT) images, linear skeletal muscle index (LSMI), was proposed and its diagnostic efficiency was verified.Methods:From April 2013 to September 2017, patients with cirrhotic gastroesophageal varices were selected from the Department of Gastroenterology, Zhongshan Hospital, Fudan University. The SMI of the third lumbar lower than 50 cm 2/m 2 in male and 39 cm 2/m 2 in female was defined as sarcopenia. The sensitivity, specificity, positive predictive value, negative predictive value, Youden index and receiver operating characteristic (ROC) curve were used to evaluate the diagnostic efficacy of LSMI in patients with cirrhotic gastroesophageal varices. Results:A total of 115 patients with cirrhotic gastroesophageal varices were finally recruited. All participants were randomly divided into modeling group ( n=58) and validation group ( n=57). In the modeling group, the area under the ROC curve of LSMI was 0.913(95% CI:0.84-0.986, P<0.001) in total population, 0.895(95% CI:0.793-0.997, P<0.001) in male and 0.917(95% CI:0.782-1.000, P<0.008) in female. The cut-off value of LSMI was 24.114 cm 2/m 2 in male and 22.54 cm 2/m 2 in female. According to the diagnostic cut-off value of the modeling group, the area under the ROC curve of LSMI was 0.846(95% CI:0.737-0.954, P<0.001) in the validation group. The sensitivity, specificity, positive predictive value, negative predictive value and Youden index were 88.5%, 80.6%, 79.3%, 89.3% and 0.691, respectively. Conclusions:48.7% of patients with cirrhosis of esophageal and gastric varices have sarcopenia. LSMI is a simple and convenient method for diagnosis of sarcopenia in patients with liver cirrhosis.

OBJECTIVE: This article summarizes the matters warranting consideration in adult cochlear implants before and after operation with different deafness causes and investigates the impact of etiological variables that affect hearing and speech ability rehabilitation after cochlear implantation. METHOD: We retrospectively reviewed the preoperative data of 30 adults who have received cochlear implantation, switch on, and periodical post operative mapping. 'Nijmegen Cochlear Implant Questionnaire' was used for every patient during follow-up and test their hearing thresholds at one year after switched-on. The average score of every patient in the six aspects of questionnaire, along with the average hearing threshold, has been gathered. RESULT: The average hearing threshold of every patient is lower than 35 dBHL. The average score of 28 patients is more than or equal to 75 in the basic sound perception, advanced sound perception as well as self-esteem. The average score of 26 patients is more than or equal to 75 in capacity for action. Besides, as for sociability and speech ability, the average score of 22 patients is more than or equal to 75. CONCLUSION Auditory perception can be greatly improved regardless of deafness causes, on the premise that appropriate candidate is selected. The primary disease should be brought under control before and after the operation. The influence of various causes to the language ability rehabilitation largely depends on the development of the language center at deafness onset. Self-esteem and social identity can be significantly enhanced after cochlear implantation in adult patients, particularly those with acquired deafness.
