Objective To study the difference of body weight gain in the first and second trimesters between pregnant women with abnormal gestational glucose metabolism and those with normal gestational glucose metabolism.Methods We retrospectively analyzed the data of pregnant women visited the obstetric clinic of Peking Union Medical College Hospital from January 2010 to May 2011,with or without abnormal glucose metabolism.The data of body weight gain in the first and second trimesters,body mass index (BMI) before pregnancy,BMI in the end of second trimester,age,obesity history,diabetes family history,insulin level in the oral glucose tolerance test (OGTT),and lipid profile of these women were collected.Results Altogether 216 pregnant women with abnormal glucose metabolism (case group) and 230 pregnant women with normal glucose metabolism (control group) were included in this study.In the case group,the increment of body weight in the first and second trimesters was 10.0 (8.1,12.5) kg,and the increment of BMI was (4.01 ± 1.43) kg/m2,BMI in the end of the second trimester was (25.84 ± 3.14) kg/m2;in comparison,the increments of body weight and BMI in the first and second trimesters were 9.5 (7.0,11.5) kg and (3.60 ± 1.43) kg/m2,respectively,BMI in the end of the second trimester was (25.1 ± 3.00) kg/m2 in the control group,all significantly lower than in the case group (all P ＜ 0.05).The BMI before pregnancy was higher in the case group than in the control group [(21.84 ±2.99) kg/m2 vs.(21.50 ±2.82) kg/m2],but with no statistical significance (P＞0.05).Compare with the control group,the case group had older age [(33.17 ±3.65) years vs.(31.68±3.36) years],higher fasting insulin level [11.2 (7.1,16.3) mU/Lvs.8.9 (6.5,13.7) mU/L],higher peak insulin level in OGTT [135.3 (99.7,208.0) mU/L vs.104.9 (75.6,144.4) mU/L],higher homeostasis model assessment for insulin resistance (HOMA-IR) [2.40 (1.49,3.47) vs.1.82 (1.28,2.71)],and triglyceride [2.62 (2.04,3.31) mmol/L vs.2.18 (1.81,2.81) mmol/L],all with significant differences (all P ＜ 0.05).There were no significant differences in obesity history,family history of diabetes and history of menstrual disorder between the two groups (all P ＞ 0.05).Conclusions The body weight gain is higher in the pregnant women with abnormal glucose metabolism than in those with normal glucose metabolism in the first and second trimesters.Large increment of body weight is likely to be a risk factor for abnormal gestational glucose metabolism.

OBJECTIVETo compare the difference in the clinical efficacy on cervical spondylosis of vertebral artery type (CSA) treated with thermosensitive moxibustion at different dosages.

METHODSSixty cases of CSA were randomized into a saturated moxa dosage group and a regular moxa dosage group, 30 cases in each one. The thermosensitive moxibustion was adopted in the two groups. The mild suspended moxibustion was applied at two acupoints with the strongest thermosensitization. In the saturated moxa dosage group, the moxibustion time was determined by the disappearance of thermosensitization. In the regular moxa dosage group, 15 min was required on each acupoint. The treatment was given twice a day for first 4 days in the two groups. Since the 5th day, the treatment was given once a day, continuously for 10 times, and totally 14 days were required. The score of symptoms and function and clinical efficacy were compared between the two groups before and after treatment as well as 6-month follow-up after treatment.

RESULTSThe curative and effective rate was 56.7% (17/30) after treatment and 60.0% (18/30) in 6-month follow-up after treatment in the saturated moxa dosage group, which were superior to 26.7% (8/30) and 30.0% (9/30) in the regular moxa dosage group respectively (P < 0.01, P < 0.05). The scores of clinical symptoms and function after treatment and in follow-up were improved apparently as compared with those before treatment in both groups (all P < 0.01). The scores of clinical symptoms and function after treatment and in follow-up in the saturated moxa dosage group were increased much more apparently than those in the regular moxa dosage group (after treatment: 22.32 +/- 4.64 vs 17.43 +/- 3.21; in follow-up: 23.01 +/- 4.76 vs 18.32 +/- 2.13, both P < 0.01).

CONCLUSIONThe thermosensitization moxibustion of saturated dosage achieves the superior short-term and long-term efficacies in the treatment of CSA as compared with the regular moxibustion dosage.

Objective To quantify the neurons in the temporal lobe white matter and find their distribution in the neurologically normal individuals.Methods The temporal lobe at the level of exterior geniculata body from brain autopsy samples of 14 neurologically normal individuals were made into large slice followed by quantitative analysis of neuron density,cell density,ratio and diameter of the neuronal nuclear and the distribution of white matter neurons using two-dimensional cell counting methods.Results With the depth of the white matter of the temporal lobe increasing,the neuron density decreased from 29.26 neurons/ mm~2 to 7.32 neurons/mm~2 and 0.00 neurons/mm~2,respectively;the cell density,neuron ratio and diameter of the neuronal nuclei all decreased.Conclusion There are neurons in the temporal lobe white matter of neurologically normal individuals,whose distribution of neurons is related to the depth of white matter.

OBJECTIVETo investigate the clinicopathologic features of focal cortical dysplasia (FCD) in patients with refractory epilepsy.

METHODSThe clinical, radiologic and pathologic features of 38 cases of FCD receiving surgical treatment in 2005 were reviewed retrospectively.

RESULTSThe mean age of disease onset was 9.2 years. The disease lasted for 11.9 years on average and often presented as complex partial seizure. Radiologic examination revealed hippocampal sclerosis, or abnormal signals in the grey matter in 21 cases. According to Palmini's classification system, the following pathologic subgroups were identified: FCD type IA (3/38), FCD type IB (20/38), FCD type IIA (5/38) and FCD type IIB (5/38). The remaining 5 cases were classified as mild cortical dysplasia. Topographically, FCD type II was often seen in the extratemporal region (8/10), predominantly in the frontal lobe (5/8). Dual pathology was identified only in cases with FCD type IB. Immunohistochemical study showed that the giant neurons, immature neurons and dysmorphic neurons were strongly positive for NeuN. A small number of balloon cells expressed nestin.

CONCLUSIONSFCD is a common cause of refractory epilepsy. FCD type IB is the predominant pathologic subtype. Associated hippocampal sclerosis is sometimes seen. Clinicopathologic differences between FCD type I and FCD type II are observed.

OBJECTIVETo study the immunohistochemical expression of OCT4, CD117 and CD30 in germ cell tumors and to assess their diagnostic value.

METHODSImmunohistochemical study for OCT4 was performed on formalin-fixed, paraffin-embedded tissues of 63 cases of germ cell tumors, including seminoma (21), dysgerminoma (7), germinoma (8), embryonal carcinoma (8), yolk sac tumor (6), mature teratoma (10) and immature teratoma (3), as well as 25 cases of non-germ cell tumors, including granulosa cell tumor (8), clear cell adenocarcinoma (4), Leydig's cell tumor (5), diffuse large B-cell lymphoma (4) and malignant melanoma (4). Besides, the expression of CD117 and CD30 in all germ cell tumors was studied.

RESULTSAll cases of seminoma and germinoma, 6/7 cases of dysgerminoma and 7/8 cases of embryonal carcinoma were positive for OCT4, with strong nuclear staining. All other germ cell tumors and non-germ cell tumors were negative for OCT4, except for 1 case of yolk sac tumor and 1 case of clear cell adenocarcinoma which showed weak staining. Positive membranous expression of CD117 was demonstrated in 19/21(90.5%) seminoma, 5/7 dysgerminoma and 7/8 germinoma. Focal weak membranous staining was also noted in 1 case of yolk sac tumor. The melanocytes in teratoma were also positive for CD117. All cases of embryonal carcinoma were negative. On the other hand, positive membranous expression of CD30 were demonstrated in 6/8 embryonal carcinoma. One case of germinoma and 1 case of yolk sac tumor showed weak cytoplasmic positivity. All cases of seminoma and dysgerminoma, 7/8 germinoma and all cases of teratoma were negative for CD30.

CONCLUSIONSOCT4 is a sensitive and relatively specific marker for diagnosing seminoma, dysgerminoma, germinoma and embryonal carcinoma. CD117 and CD30 immunostains, when used in combination, represent valuable tools for distinguishing embryonal carcinoma and seminoma, dysgerminoma, germinoma.

Anemarrhena asphodeloides processed by salt and raw product was compared including both chemical composition and laxative function in order to find the possible active substance to cure constipation. Processed and raw Anemarrhenae laxative effect on experimental constipation models was observed as well as chemical composition using UPLC-MS technology and the total sugar content was determined by phenol sulfuric acid method. Processed Anemarrhenae water extract improved excrement more than raw which has significant difference compared with the blank group (P < 0.05). On the other hand, the total ion flow spectrum showed no significant difference in most substance, but the total sugar content was significantly higher than raw product. Anemarrhenae ancient be recognized benefitting for draining body water in traditional Chinese medicine which has been lost in modern books because it is manifested as excellent laxative effect not diuretic effect. Saccharides carbohydrate may have closely relationship with this magically effect.

Objective: To investigate the relationship between P27，P53 and PCNA expression in human gastric carcinoma tissues and clinicopathological parameters. Methods: The expression of P27，P53 and PCNA in 62 human gastric carcinoma tissues was examined with immunohistochemistry SP method. Results: Positive rates of P27，P53 and PCNA expression were 37.1％, 40.4%，83.9％. P27 expression was related with Bormann type, infiltrative depth, lymph node and distant metastasis and clinical stage. P53 expression was related with sex of patients, distant metastasis and clinical stage. PCNA expression was related with age of patients and infiltrative depth of tumor. P27 positive expression group was higher than negative group as to 5-year survival. P27 expression was in reverse relation with PCNA expression. Conclusion: The expression of P27, P53 and PCNA may be regarded as an important marker in judging malignant degree of gastric carcinoma,distant metastasis and prognosis.
