Objective To investigate the short-term outcome of laparoscopic adjustable gastric banding (LAGB) for morbid obesity complicated with type 2 diabetes. Methods Eight morbidly obese patients with type 2 diabetes underwent LAGB from October 2006 to August 2007. The weight parameters, fasting (FBG) and 2-hour blood glucose (2hBG), medication for diabetes were assessed 1,3, 6 and 9 months after surgery. Results All of the patients lost weight, with a mean body mass index decreased from (38.7±7.5) kg/m2 before LAGB to (30.5±4.3) kg/m2 9 months after LAGB. The FBG and 2hBG were decreased significantly at month 6 and 9 after LAGB, with normal FBG and 2hBG in 4 patients. At month 9 after LAGB, 3 of 5 patients with insulin treatment before LAGB were changed to oral hypoglycemics, 1 was continuously administered with a reduced dose of insulin, and 4 patients stopped any medication. Conclusion LAGB is an effective procedure in the treatment of morbid obesity complicated with type 2 diabetes with a favorable short-term outcome.

. Conclusions Two multiplex RT-PCR assays show high consistency with common RT-PCR. The multiplex RT-PCR assays were initially established.

OBJECTIVETo investigate the female sexual dysfunction (FSD) in type 2 diabetes patients, by comparing the sexual function between type 2 diabetic women and non-diabetic women with Female Sexual Function Index (FSFI).

METHODS115 type 2 diabetic women and 107 age-matched non-diabetes women were enrolled with similar backgrounds. Their sexual functions were evaluated with FSFI. Metabolic parameters such as body mass index, blood lipid profile, hemoglobin A1C, plasma glucose were also collected.

RESULTSTotal score of FSFI of the type 2 diabetic women were significantly lower than that of the non-diabetic controls (18.27±8.96 vs. 23.02±5.78, P=0.000). Scores of the FSFI domains (desire, arousal, lubrication, orgasm, satisfaction, pain) of the type 2 diabetic group were also lower than those of the control group. According to the FSD criterion (FSFI<25) available in China, the percentage of FSD in the type 2 diabetic group was significantly higher than that of the control group (79.2%vs. 55.0%, P<0.001). These trends seemed more prominent in pre-menopause subgroups. The logistic regression analysis indicated that age and diabetes were independent risk factors of FSD. Body Mass Index (BMI) also had influence in the diabetes group.

CONCLUSIONFindings from this study showed that there are more FDS in Chinese type 2 diabetic women than in their non-diabetic counterparts, especially in pre-menopause participants.

OBJECTIVETo explore factors affecting occupational adaptability in nurses for offering basis to increase their occupational adaptability.

METHODSFive hundred and forty-five nurses were investigated with work ability index questionnaire and occupational stress instruments.

RESULTSThere were many risk factors affecting occupational adaptability in nurses. The main variables that influenced occupational adaptability included work-overtime, mental load, social support, physical environment, and job hazards. The social support was the factor increasing the occupational adaptability of the nurses (P < 0.01, OR = 0.912). Five factors including work overtime, mental load, social support, physical environment and job hazards were introduced in the Logistic equation. The established functions were: Logit (P) = -11.357 + 1.011x(1) + 0.335x(2) - 0.076x(3) + 0.260x(4) + 0.129x(5).

CONCLUSIONThere are many risk factors affecting occupational adaptability in nurses. Relevant measures should be taken to promote the occupational adaptability in nurses to reduce the risk factors.

This study was aimed to explore the expression of survivin in leukemia cells and to investigate the effect of GM-CSF on survivin expression. The survivin expressions in 37 previously untreated leukemia patients and 10 normal persons as well as in three kinds of leukemia cell lines (K562, HL-60, U937) were analyzed by RT-PCR. The HL-60 cells were treated by the proper concentration of GM-CSF, and the changes of survivin mRNA and protein expression levels were detected by using RT-PCR and Western blot respectively. The results indicated that the positive rate of survivin gene in 37 leukemia patients was 67.6% (25/37) and significantly higher than that in normal control (20.0%). The expression level was higher in ALL cells than that in AML cells (73.3% vs 63.6%). Moreover, three kinds of leukemia cell lines all expressed survivin. After treating with the proper concentration of GM-CSF for 2 days, the expression of survivin obviously increased and the expression level of survivin mRNA was up-regulated by 26%, the expression level of survivin protein was up-regulated by 49%. It is concluded that the survivin gene extensively express in leukemia and its cell lines, and its expression can be obviously increased by GM-CSF.

Survivin, a new member of the inhibitor of apoptosis protein (IAP) family, expressed in the most human cancers but not in terminally differentiated adult tissues, so survivin may be a target for tumor therapy. In addition, some scholars found that survivin expression is associated with the resistance in chemotherapy. To explore the relationship between survivin and drug-resistance, the alteration of survivin mRNA and protein of HL-60 cells treated with daunomycin (DNR), mitoxantrone (MIT) and arsenic trioxide (As2O3) was investigated, the expressions of survivin mRNA and survivin protein were detected on the first and third day by RT-PCR and Western blot, respectively. The results showed that survivin mRNA levels all decreased after the first day of treatment with drugs. It was decreased by 10% in DNR group, 40% (P < 0.01) in MIT group, and 25% (P < 0.01) in As2O3 group in comparison with control cells. In the third day, the survivin mRNA treated with DNR was up-regulated by 20% (P < 0.05), compared with the first day, and MIT was up-regulated by 65% (P < 0.01), but As2O3 was still down-regulated by 32% (P < 0.01). In Western blot, survivin protein level increased 14% after treated with DNR for three days, compared with the control cells, and 11% in MIT, but decreased by 82% in As2O3. It is concluded that after treatment with chemotherapeutic drugs, the survivin level descended at first day and then ascended obviously. This phenomenon may be associated with the resistance in chemotherapy for leukemia. On the other hand, As2O3 shows a different mechanism that may play a significant role to reverse resistance.

AIMThe electrographic and behavioral kindling effects were induced by chronic tetanization of the right caudate-putamen (CPu) to study the target-behavior expression involved in the CPu or hippocampus (HPC) network abnormalities.

METHODSExperiments were performed on 58 SD rats. Tetanization (60Hz,0.4 - 0.6mA, 2s) was delivered into the CPu or the HPC, once a day, for 7-12 days. Animal behaviors were observed every day and depth electrographs were recorded at the beginning or at the end of the experiments.

RESULTSChronic tetanization of the CPu or of the HPC induced: (1) Rhythmic sharp waves in the CPu and paroxysmal epileptiform events in the HPC electrographs. (2) Primary behavioral seizures, secondary behavioral seizures, and kindling effects, including wet dog shakes (WEDS), rearing, face washing, immobility, chewing and head nodding. (3) Lower rate of primary WEDS (P < 0.01), and higher rate of secondary WEDS (P < 0.01) in the CPu-tetanized rats. (4) Longer silent period of behavioral seizures before kindling appeared in the CPu-tetanized rats.

CONCLUSIONKindling effects in the CPu-tetanized rats resembles those in the HPC-tetanized rats. The CPu might participate in the origin of epileptic focus and be involved in reestablishment of limbic epileptic networks, which may be responsible for the target-behavioral seizures.

AIMTo study the characteristics of neural information encoding of the epileptic networks involved caudate-putamen(CPu) and the hippocampi induced by tetanization of the right CPu in rats.

METHODSExperiments were performed on 59 SD rats. Acute or chronic tetanization of the right CPu (ATRC or CTRC) (60Hz,0.4-0.6 mA, 2 s) was used to induce rat epilepsy.

RESULTS(1) The bursting or primary unit afterdischarges of single neurons were asymmetric in dual hippocampi induced by the ATRC. (2) Continuous sharp waves were observed in ipsilateral or contralateral CPu induced by the CTRC. The oscillatory network seizures with phase shift appeared between two sharp waves in ipsilateral CPu. The frequency of oscillatory waves was negatively correlated with the time and fluctuated from 70 Hz to 110 Hz, then to 35 Hz, and finally to 30 Hz. (3) In the contralateral side primary network after discharges in the CPu were induced by the CTRC. Therefore, the characteristic primary network afterdischarges could be shifted from the CPu or to the HPC, but amplified. On the other hand, HPC sharp waves could be depressed when the CPu network seizures occurred.

CONCLUSIONThe reestablishment of CPu-hippocampal epileptic networks could be transhemispherically promoted by over-activation of the right CPu network, in which bilateral hippocampal neuronal network and CPu neural network were involved in some particular pathophysiological information encoding.
