Objective To evaluate the surgical approaches, surgical timing and materials for cranial defect repair in children. Methods From the year 2002 to 2006, 4 children with cranial defect received cranial reconstruction using absorbable poly-L-lactic acid (PLA) material and hydroxyapatite. Results The 3-year follow-up showed that the cranial defect was successfully repaired using the absorbable material in 3 patients and failure of repair occurred in 1 patient. Conclusion Cranial defect in children can be effectively repaired using absorbable materials and hydroxyapatite without obviously affecting the skull development. This approach provides an important option for cranial defect repair in children.

OBJECTIVETo explore the effect of new model for tuberculosis (TB) control and management, and provide a scientific basis and justification for making TB control strategies in rural communities.

METHODSAmong those townships with low TB service accessibility by the county TB control institute in Guangxi Xingye county (population of 679 thousands), four townships with total population of 152 518 and inconvenient transportation, were selected as the experimental group to conduct a new model research project.Based on the accessibility for community services, setting diagnosis and treatment management centers in township hospitals, employing family treatment supporters to supervise the treatment process. The TB cases of the base-line and the project expiration of the experimental group were 44 and 117. Meanwhile, three townships including Dapingshan, Longan and Gaofeng in the county with the similar condition and total population of 133 303 were selected as the control group. The control group conducted the provisions of national TB control program in the county TB clinic management. The TB cases of the base-line and the project expiration of the control group were 56 and 110. By double-direction comparison method, the effect of the new model was evaluated through TB patients detection, treatment outcomes and TB control management data. SPSS 13.0 statistical software was adopted and Chi-square test was used for analyzing technical data.

RESULTSAfter two-year project research implementation, in the experimental group the detection rate of new smear-positive TB patients increased from 16.39/100 000 (25/152 518) to 51.14/100 000 (78/152 518) (χ(2) = 27.281, P < 0.01), the cure rate of new smear-positive cases increased from 71.4% (15/21)to 91.1% (51/56) (χ(2) = 4.812, P < 0.05), and the completing treatment rate in newly diagnosed smear-negative cases improved from 23.5% (4/17)to 71.4% (15/21) (χ(2) = 8.622, P < 0.01); the loss rate of newly diagnosed smear-positive cases dropped from 23.8% (5/21) to 0.0% (0/56) (χ(2) = 10.608, P < 0.01), and the loss rate of newly diagnosed smear-negative cases decreased from 64.7% (11/17) to 4.8% (1/21) (χ(2) = 15.624, P < 0.01). Meanwhile, the cure rate of new smear-positive cases in the experimental group, 91.1% (51/56), was higher than the control group, 72.0% (36/50) (χ(2) = 6.531, P < 0.05). The loss rate of newly diagnosed smear-positive cases in the experimental group (0.0% (0/56)) was lower than the control group (16.0% (8/50)) (χ(2) = 7.534, P < 0.01). During the project implementation, in the experimental group the on time rate of taking medicine, 91.5% (107/117) and receiving medicine, 100.0% (117/117), the reexamining sputum ratio, 83.6% (98/117) were higher than that in the control group: 81.8% (90/110), 92.7% (102/110) and 64.5% (71/110). The differences were statistically significant (χ(2) = 4.589, 8.820 and 11.005, P < 0.05).

CONCLUSIONThe new management model had been proved effective. It can improve TB case detection and cure rates, reduce the loss rate of patients, and improve patient treatment and management conditions as well.

OBJECTIVE: To explore whether the high risk factors possibly leading to hypercoagulative status and thrombosis exist in Thalassemia patients of Guangxi region through detecting plasma tissne factor-bearing microparticles (TFMP), procoagulatima activity, coagulation and anticoagulation function, fibrinolytic function, endothelial function and platelet count. METHODS: The TFMP procoagulation activity was detected by chromogenic saubstract method, the levels of tissue factors (TF), tissue factor pathway inhibitor(TFPI), protein C (PC), protein S (PS), antithrombin Ⅲ(AT-Ⅲ), tissue plasminogen activator (tPA), thrombin-activated fibrinolysis inhibitor (TAFI), soluble E-selectin (sE-sel), intercellular adhesion molecule-1 (ICAM-1) and thrombomodulin (TM) were detected by ELISA in thalassemia group (n=71) and control group (n=20 heathy persons). RESULTS: Compared with control group, the AT-Ⅲ level decreased in β-thalastemia major group (TM) (P<0.05), the AT-Ⅲ level in TM group independeutly posstiody correlated with plt count (r=0.37, P<0.05); the levels of TF and sICAM in α-thalassenia intermediate group (TA) significantly decteased (P<0.05), the procoagulatim activity of TFMP in β-thalassemia intermediate group (TI) increased sngnificantly (P<0.05)， moreover positively corretated with AT-Ⅲ level (r=0.77, P<0.05). The TF and sICAM-1 levels in normal liver functim group of Thalassemia patients were lower tham those in control group (P<0.01 and P<0.05, respectively), the TFMP activity between normal and abnormal liver function was significantly different (P<0.05), while there were no significant difference in other correspoding indexes beween thalassemia group and control group as well as between each thalassemia groups. CONCLUSION The damage of liver function and reduction of anticoagylation substances exist in patients with β-thalassenia major in Guangxi region, the procoagulation activity of plasma TFMP in patients with β-thalassemia intermedia abnormally increases. All the above-mentioned factors may increase the risk of high coagulation status or thrombosis is thalassemia patients, the decrease of TF and SICAM-1 levels in patients with α-thalassemia intermedia may be factor against thrombosis.

OBJECTIVETo investigate the clinicopathological characteristics and prognosis in breast cancer with brain metastasis (BCBM).

METHODSThe clinical data of 137 BCBM from June 2002 to June 2008 was reviewed and analyzed. Their molecular subtypes were categorized based on detection of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2) expression. The focal area included 35 cases of triple-negative breast cancer (TNBC), 38 cases of HR (ER and PR) (-)/HER-2(+), 40 cases of HR(+)/HER-2(-), 24 cases of HR(+)/HER-2(+). The clinical characteristics and the outcome in patients with influence were analyzed.

RESULTSIn 137 BCBM, the median overal survival after brain metastasis was 6.5 month. The median survivals of TNBC, HR(-)/HER-2(+), HR(+)/HER-2(-) and HR(+)/HER-2(+) were 5.0, 5.5, 10.0 and 9.5 months, respectively. The median survivals after brain metastasis of the breast cancer patients who received the combination therapy of whole brain radiation therapy (WBRT) and neurosurgery and/or stereotactic radiosurgery, received WBRT but not combination therapy and didn't receive WBRT were 15.0, 9.5 and 4.0 months, respectively. In univariate survival analysis, substyle, number of brain metastasis, brain metastasis as initial recurrence or not, brain-only metastases or not, the combination therapy status after brain metastasis were obviously correlated with the prognosis (χ(2) = 6.891 to 29.414, P < 0.05). Substyle (RR = 1.234, 95%CI: 1.057 to 1.440) and the combination therapy status after brain metastasis (RR = 1.838, 95%CI: 1.389 to 2.431) were independent prognostic factor in multivariable analysis (P < 0.05).

CONCLUSIONSTNBC confers a high risk of death after brain metastases. Systemic treatment via combined modalities are helpful for breast cancer patients, even after the detection of brain metastases.

BACKGROUNDAlthough thalamotomy could dramatically improve both parkinsonian resting tremor and essential tremor (ET), the mechanisms are obviously different. This study aimed to investigate the neuronal activities in the ventrolateral thalamus of Parkinson's disease (PD) and ET.

METHODSThirty-six patients (PD: 20, ET: 16) were studied. Microelectrode recordings in the ventral oral posterior (Vop) and the ventral intermediate nucleus (Vim) of thalamus was performed on these patients who underwent thalamotomy. Electromyography (EMG) was recorded simultaneously on the contralateral limbs to surgery. Single unit analysis and the interspike intervals (ISIs) were measured for each neuronal type. ISI histogram and auto-correlograms were constructed to estimate the pattern of neuronal firing. Mann-Whitney test and Kruskal-Wallis (K-W) test were used to compare the mean spontaneous firing rate (MSFR) of neurons of PD and ET patients.

RESULTSThree hundred and twenty-three neurons were obtained from 20 PD trajectories, including 151 (46.7%) tremor related neuronal activity, 74 neurons (22.9%) with tonic firing, and 98 (30.4%) neurons with irregular discharge. One hundred and eighty-seven neurons were identified from 16 ET trajectories including 46 (24.6%) tremor-related neuronal activity, 77 (41.2%) neurons with tonic firing, and 64 neurons (34.2%) with irregular discharge. The analysis of MSFR of neurons with tonic firing was 26.7 (3.4 - 68.3) Hz (n = 74) and that of neurons with irregular discharge (n = 98) was 13.9 (3.0 - 58.1) Hz in PD; whereas MSFR of neurons with tonic firing (n = 77) was 48.8 (19.0 - 135.5) Hz and that of neurons with irregular discharge (n = 64) was 26.3 (8.7 - 84.7) Hz in ET. There were significant differences in the MSFR of two types of neuron for PD and ET (K-W test, both P < 0.05). Significant differences in the MSFR of neuron were also obtained from Vop and Vim of PD and ET (16.3 Hz vs. 34.8 Hz, 28.0 Hz vs. 49.9 Hz) (K-W test, both P < 0.05), respectively.

CONCLUSIONIn consistent with recent findings, the decreased MSFR of neurons observed in the Vop is likely to be involved in PD whereas the increased MSFR of neurons seen in the Vim may be a cause of ET.

OBJECTIVETo investigate the correlation between expression of A-kinase anchoring protein 95 (AKAP95) and protein expression of cyclin E1 and cyclin D1 in lung cancer tissue.

METHODSFifty-one cases of lung cancer were included in the study. The protein expression of AKAP95, cyclin E1, and cyclin D1 were measured by immunohistochemistry.

RESULTSThe protein expression of cyclin E1 in lung cancer tissues was significantly higher than that in para-cancerous tissues (positive rate: 75.56%vs 20%, P < 0.01); its expression showed no relationship with histopathological type, lymph node metastasis, and cellular differentiation (P > 0.05). The protein expression of cyclin D1 in lung cancer tissues was higher than that in para-cancerous tissues (positive rate: 69.39% vs 14.29%); its expression showed a significant relationship with histopathological type (P < 0.05). The expression of AKAP95 was correlated with the protein expression of cyclin E1 and cyclin D1 in lung cancer tissues (P < 0.01).

CONCLUSIONCyclin E1 and cyclin D1 are highly expressed in lung cancer tissue, suggesting that they play an important role in the development and progression of lung cancer. The protein expression of cyclin E1 has no relationship with cellular differentiation, lymph node metastasis, and histopathological type of lung cancer, and the protein expression of cyclin D1 has a significant relationship with histopathological type. The expression of AKAP95 is correlated with the protein expression of cyclin E1 and cyclin D1 in lung cancer tissue.

OBJECTIVETo study the dynamics of peripheral blood B lymphocytes and natural killer (NK) cells in patients with severe acute respiratory syndrome (SARS).

METHODSThe absolute numbers of peripheral blood B lymphocytes and NK cells in 602 serial samples from 240 patients with SARS were counted, using flow cytometry, and compared with that of normal population.

RESULTSThe absolute numbers of peripheral blood B lymphocytes and NK cells in SARS patients were significantly lower than that of the normal population (P < 0.001) and were much lower in SARS patients with severe or extremely severe types, as compared with that of moderate or mild type cases (P < 0.001). The amount of B lymphocytes in recovery SARS patients increased at the 2nd week after onset, and gradually becoming normal at the 5th week of the disease onset. The number of NK cells was in the low level at onset, and keep decreasing at the 2nd week. However, it was increasing with the recovery of the disease, but did not reach to normal level at the 5th week after onset.

CONCLUSIONThe absolute numbers of peripheral blood B lymphocytes and NK cells were associated with the severity of the disease, and detection of these two kinds of cells was useful for predicting the prognosis of SARS.

Objective:To investigate the main clinical characteristics, imaging features, diagnosis, and treatment of meningiomas initially manifesting as spontaneous intracranial hemorrhage.Methods:The clinical characteristics, imaging features, treatment, and follow-up data of 19 patients with meningiomas initially manifesting as spontaneous intracranial hemorrhage who received treatment in The First Affiliated Hospital of Shantou University Medical College from January 2011 to December 2020 were retrospectively analyzed.Results:Among the 19 patients, there were 6 males and 13 females, with an average age of (53 ± 14) years. The onset manifestations were sudden and severe headache and vomiting in 6 cases, progressive coma in 4 cases, and hemiplegia in 9 cases. Among the 19 patients, 15 patients showed irregular tumor shape and mixed hyperintense signal in CT, and 4 patients showed a homogeneous hyperintense signal. Eighteen patients showed peritumoral edema. Three patients showed intratumoral calcification. One patient showed an intratumoral fluid level. Fourteen patients showed isointense to hypointense signals on T1WI images and isointense to hyperintense signals on T 2WI images. Five patients showed mixed isointense and hyperintense signals on T 1WI images and mixed hypointense and hyperintense signals on T 2WI images. Heterogeneous enhancement was found in 18 patients, intratumoral cystic necrosis was found in 15 patients, and the meningeal tail sign was found in 16 patients. Preoperative imaging misdiagnosis occurred in 4 patients. Before surgery, all patients underwent surgery to resect the tumor and remove the hematoma. No patients died because of surgery. After surgery, muscle strength was improved compared with that before surgery. The average follow-up time was (46.5 ± 28.4) months. Tumor recurrence occurred in two patients. The Karnofsky Performance Scale score at the last follow-up, at discharge, and before surgery was (73.7 ± 3.4) points, (61.1 ± 5.5) points, and (49.5 ± 5.6) points, respectively ( F = 21.06, P < 0.01). The Karnofsky Performance Scale score at the last follow-up was significantly increased compared with that at discharge and before surgery ( F = 13.13, P < 0.01). Conclusion:Spontaneous hemorrhagic meningioma is rare and has a sudden onset. It is easily misdiagnosed before surgery. Skull CT, skull CT angiography, and enhanced magnetic resonance imaging examination in combination can increase the preoperative diagnosis rate. Early surgical resection of tumors and removal of hematoma can acquire good clinical efficacy.

OBJECTIVEThis study aimed to investigate the depression status among high-risk pregnancy women, and to analyze its relevant social and psychological factors.

METHODSA total of 42 high-risk pregnancy women and 40 normal pregnancy women in a teaching hospital in Harbin city were followed up at time points of 32 - 36 weeks pregnancy, one week before labor, one week postpartum, and six weeks postpartum, respectively. During follow-up, the basic situation, social psychosocial factors of pregnancy women were collected and the depression of pregnancy women was measured by self-designed questionnaire and self-rating depression scale. The Edinburgh Postnatal Depression Scale (EPDS) was applied at timepoint of one week postpartum. Single factor analysis and the unconditional multivariate logistic regression were applied for analyzing the on the related social-psychosocial factors among high-risk pregnancy women.

RESULTSThe age of high-risk pregnancy women was (31.0±5.6), and the age of normal pregnancy women was (30.5±3.8) (t=0.169, P>0.05). The results showed that the depression rate in high-risk pregnancy women was 45.2% (19/42), which was 25.0% (10/40) in normal pregnancy women, the difference was significant (χ2=3.671, P=0.045). The depression rates at different time points were 30.9% (13/42), 42.9% (18/42), 23.8% (10/42), 26.2% (11/42) in high-risk pregnancy women respectively, and 25.0% (10/40), 15.0% (6/40), 20.0% (8/40), 17.5% (7/40) in the control group respectively, the difference of the depression rates among groups at one week before labor was significant (χ2=7.680, P<0.01), the difference among groups at 32-36 weeks pregnancy (χ2=0.133, P=0.80), at one week postpartum (χ2=0.174, P=0.79) and at six weeks postpartum (χ2=0.903, P=0.43) were not significant. At one week postpartum and six weeks postpartum periods, the EPDS depression rate were 12.5% (4/32), 30.4% (7/23) in case group respectively, 8.3% (3/36), 22.9% (8/35) in control group respectively, the difference were not significant (χ2=0.319, 0.416, P=0.573, 0.519). There were significantly associations between the depression mood of one week before labor and the depressive symptoms of six weeks postpartum in both groups (r=0.824, 0.677, both P values were <0.05). The risk factors for maternal depression among high-risk pregnancy women were not ready for production (OR=2.73, P<0.01) and fearing of childbirth safety (OR=2.89, P<0.01).

CONCLUSIONThe depression date of high-risk pregnancy was high, especially at the time point one week before labor. Risk factors of maternal depression among high-risk pregnancy were "not ready for production" and "fear of childbirth safety".
