In our gastroenterology clinic from Jun. 2008 to Jan. 2009, 20. 9% (277/1320) patients were diagnosed with functional dyspepsia (FD) and 14. 8% (41/277) of them with psychological problems according to Minnesota Multiphasic Personality Inventory (MMPI). In those with psychological disorders,92.7% were found with somatization, 60. 9% with depression and anxiety, 97.6% with abdominal pain,75.6% with bloating, 63.4% with early fullness and 36. 6% with nausea. More than 80% patients with anxiety and depression complained irritability, worry, fatigue, poor concentration, memory loss and insomni.a. After 4 weeks of psychological consultation and anti-depression treatment, 5 patients had significant improvement, 31 had improvement and 3 had no response. The overall response rate was 87. 8%.In summary,there is a high prevalence of depression and anxiety in population with FD. Hypochondria and somatization are common among these patients. Psychological consultation with anxiolytic drugs may have good therapeutic effects.

Objective: To clone the cDNA of human sPLA2-IIA,construct the engineered Escherischia coli expressing human sPLA2-IIA and identify the expressed human sPLA2-IIA. Methods: Total RNAs were purified from human fetal spleen. The cDNA of human sPLA2-IIA was cloned by RT-PCR and inserted into plasmid pET32a(+) between NcoI and EcoRI sites for expressing the recombinant human sPLA2-IIA in Escherischia coli BL21(DE3). The recombinants were screened by SDS-PAGE. The engineered Escherischia coli expressing trxA-human sPLA2-IIA fusion protein was established. The expressed human sPLA2-IIA exists in the form of inclusion body and accounts for about 25% of the total proteins of Escherischia coli BL21(DE3). Conclusion: the engineered E. coli methods are suitable for preparing plenty of human sPLA2-IIA which has laid base for the large-scale expression,purification and basic studies of human sPLA2-IIA.

Objective To study the correlations between bone fracture types and healing time in patients with osteofluorosis. Methods Thirty-seven patients with osteefluorosis and long tubular bone fracture were diagnosed in accordance with radiogram retrospectively. The fractures were divided into two groups: sclerotic and osteoporotic. Twenty four fractured patients with non osteofluorosis were included in the study as controls. All of the patients had operation(open reduction and nickelclad internal fixation). Fracture healing in patients with sclerotic and osteoporotic groups was compared with the control group after operation. Results There were notable differenees(F=4.30,P< 0.05) in term of fracture healing time among the three groups [sclerotic group:(18.4±5.3)weeks; osteoporotic group: (24.5±5.1)weeks; control group: (17.6±3.8)weeks]. Notably, there were significant differences between the osteoporotic and control groups(q=2.34,P<0.05), and between sclerotic and osteoporotic gronps(q=2.51, P<0.05). The healing time of the osteoporotic group was longer than that of sclerotic group. The constituent ratios of fracture healing in sclerotic, osteoporotic and control groups were 73.1% (19/26) ,54.5% (6/11),75.0% (18/24) respectively, and the differences among the three groups were statistically significant(X2=3.67,P<0.05). The healing rate of the osteoporotic group was lower than that of sclerotic and control groups(X2=3.12, 3.36, all P< 0.05). The constituent ratios of healing in the sclerotic, osteoporotic and control groups were 26.9% (7/26),45.5% (5/11),25.0%(6/24), respectively, and there differences among the three groups were statistically significant (X2=4.07 ,P<0.05). The delayed healing rate of the osteoperotic group was higher than those of the sclerotic and control groups(X2= 3.87,3.95, all P<0.05). Conclusions Fracture healing time of osteoporotic osteofluorosis after fracture is longer than normal, and the cause might be the loss of bone mass.

Objective To observe the effect of light emitting diode (LED) red light irradiation on serum lipid in experimental hyperlipidemia rats. Methods 36 healthy male Sprague-Dawley rats were randomly divided into normal control group (n=12) and hyperlipidemic model group (n=24). The normal group was fed with normal diet while the hyperlipidemic model group with fat-rich forage for 6 weeks. The hyperlipidemic model group rats were randomly divided into the hyperlipidemic control group (n=12) and LED treatment group (n=12), and the latter accepted LED red light irradiation for 28 d. The levels of serum lipid including total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C), high-density lipoprotein (HDL-C), and the activities of lipoproteinesterase (LPL) and hepatic lipase (HL) were detected with biochemical assay. The expression of 3-hydroxy-3-methylglutaryl coenzyme A reducase (HMG-CR) of hepatic tissue were measured with immunohistochemical staining. Results Compared with the hyperlipidemic control group, the levels of serum TC, TG and LDL-C decreased while the serum HDL-C increased significantly in the LED treatment group (P<0.01) after treated with LED. The levels of LPL and HL in serum increased (P<0.01) while the activity of HMG-CR decreased (P<0.05). Conclusion LED red light irradiation might play a regulating effect on serum lipid by enhancing the activities of LPL and HL and inhibiting the expression of HMG-CR to interfere the metabolism of TC, TG, LDL-C and HDL-C.

OBJECTIVETo study the possible mechanism of protective effect for Baicalin on Bacillus pertussis (BP) infected brain tissue and the dose-effect relationship.
METHODSBrain tissues slices were divided into 7 groups: (1) the normal group; (2) the model group: infected by 10% BP; (3) the baicalin group, which was pretreated with baicalin, infected by BP and subdivided into 5 sub-groups according to different doses of baicalin used; (4) the glutamic acid group: cultured with glutamic acid; (5) the baicalin plus glutamic acid group; (6) the peroxide group: cultured with hydrogen peroxide; and (7) the baicalin plus peroxide group. The lactate dehydrogenase (LDH) content in the supernatant of culture was determined and quantitative protein determination was conducted.
RESULTSThe LDH releasing was higher in the model group, glutamic acid group and peroxide group as compared with that in the normal group, 15.10 +/- 4.89 u/g. protein (the same unit below), 15.49 +/- 5.66 and 16.54 +/- 5.47 vs 6.10 +/- 2.87 respectively (P < 0.01). After being pretreated with 0.25 mmol/L baicalin, LDH level decreased significantly to 8.65 +/- 2.43, which was significantly different from that in the model group (P < 0.01), LDH was also decreased in the baicalin plus glutamic acid group (9.93 +/- 2.89) and baicalin plus peroxide group (9.54 +/- 2.82), which was significantly lower than that in the glutamic acid group and the peroxide group respectively (P < 0.01).
CONCLUSIONPretreatment of baicalin has protective effect on BP caused nerve cell injury in rat brain slices, the protection is possibly related with the reduction of glutamic acid and hydrogen peroxide induced damage on nerve cells in vitro.

OBJECTIVETo summarize the features and treatment of male infertility induced by autosomal dominant polycystic kidney disease (ADPKD), and compare the outcomes of intracytoplasmic sperm injection (ICSI) for infertile men with ADPKD and those with congenital bilateral absence of vas deferens (CBAVD).
METHODSWe retrospectively analyzed 21 cases of ADPKD-induced infertility, 15 treated by ICSI (group A), and another 164 cases of strictly matched CBAVD-induced infertility (group B). We compared the two groups in the couples' age, the number of ICSI oocytes, and the rates of fertilization, transferrable embryos, good embryos, embryos implanted, clinical pregnancy, biochemical pregnancy, early abortion, singleton and twins in the first cycle.
RESULTSAfter 28 cycles of ICSI, 10 of the 15 ADPKD-induced infertility patients achieved clinical pregnancy, including 7 cases of live birth, 1 case of spontaneous abortion, and 2 cases of pregnancy maintenance. No significant differences were observed between groups A and B in the couples' age, the wives' BMI, or the numbers of ICSI oocytes and embryos transplanted (P >0.05), nor in the rates of ICSI fertilization (72.64% vs 76.17%), transferrable embryos (51.28% vs 63.24%), quality embryos (38.46% vs 49.83%), embryo implantation (17.64% vs 38.50%), abortion (0 vs 9.23%), singleton (50% vs 81.54%) and twins (50% vs 18.46%). However, the rates of clinical pregnancy (13.33% vs 42.68%, P = 0.023 <0.05) and biochemical pregnancy (13.33% vs 39.63%, P = 0.032 <0.05) were significantly lower in group A than in B.
CONCLUSIONICSI is effective in the treatment of male infertility induced by either ADPKD or CBAVD, but the ADPKD cases have a lower success rate than the CBAVD cases in an individual cycle. The affected couples should be informed of the necessity of prenatal genetic diagnosis before embryo implantation and the inevitable vertical transmission of genetic problems to the offspring.

Objective To investigate the effect of transcranial direct current stimulation (tDCS) on aphasia recovery after stroke. Meth-ods From April, 2012 to January, 2013, 20 aphasic patients after stroke were enrolled in an A-B experiment design. During phase A, ten times of sham tDCS and language training (five days a week) were implemented, then ten times language training combined with tDCS (five days a week) were implemented in phase B. The treatment lasted for four weeks. Picture naming was measured for all patients before and af-ter treatment both in phase A and phase B. Results The D-value scores of picture naming before and after treatment were significantly more in phase B than in phase A in both treatment items and non-treatment items (t>3.030, P<0.05). Conclusion tDCS could raise the accuracy of picture naming in patients with aphasia after stroke.
