OBJECTIVETo study psychiatric features and the manifestations of central nervous system involvement in Chinese patients with primary Sjogren's syndrome (PSS).

METHODSThe Minnesota Multiphasic Personality Inventory (MMPI) was used to study 27 PSS female patients and 57 healthy women. The results from two groups were compared. Ten SS patients were evaluated by electroencephalography (EEG), transcranial doppler ultrasound (TCD) and magnetic resonance imaging (MRI).

RESULTSOf 27 patients tested, the three highest clinical mean scales included Hypochondriasis (Hs), Hysteria (Hy), Psychasthenia (Pt) were found. When PSS group was compared with normal control, T scores of SS patients were significantly higher than the healthy women in Hs, Hy. Abnormal EEG was found in 3 of 9 PSS patients. TCD was abnormal in 5 of 9 patients. MRI in 1 patient showed abnormality.

CONCLUSIONSThis study shows that the personality of PSS patients is abnormal, the features are neuroticism. Central nervous system was markedly involved in Chinese patients with PSS, including abnormal EEG and TCD. The changes of central nervous system may be related to abnormalities of psychiatric changes.

OBJECTIVETo compare the efficacy and adverse effects between arsenic trioxide (ATO) and all-trans retinoic acid (ATRA) in patients with acute promyelocytic leukemia (APL).

METHODSThe clinical data of 71 patients with newly diagnosed APL were retrospectively analyzed. Two groups were classified according to the induction regimens, namely ATO group (n = 41) and ATRA group (n = 30). The complete remission (CR) rate and the time to CR were compared between these two groups.

RESULTSThe CR rate was 97.5% in ATO group and 93.3% in ATRA group (P > 0.05). The median time to CR was 29 days (21-45 days) in ATO group, which was significantly shorter than 38.5 days (24-63 days) in ATRA group (P < 0.001). Retinoic acid syndrome occurred in 52.9% of patients treated with ATRA, which affected the further use of ATRA.

CONCLUSIONSBoth ATO and ATRA have high response rates for newly diagnosed patients with APL. Compared with ATRA, ATO induction therapy has shorter time to achieve CR and less adverse effects, and therefore may be the first-line therapy for APL.

OBJECTIVETo detect gene mutations associated with autosomal dominant congenital stationary night blindness(ADCSNB) in a large Chinese family.

METHODSGenomic DNAs were extracted from peripheral blood samples of 16 affected and 14 unaffected family members. According to 5 missense mutations in 3 genes reported previously, 4 pairs of primers were designed and corresponding exons containing the five mutation sites were amplified by polymerase chain reaction. Amplified products were purified and sequenced by MegaBACE1000 capillary array electrophoresis DNA sequencer. Full field electroretinogram (ERG, ISCEV) of patients was recorded and analyzed by Roland Consult System.

RESULTSDark-adapted ERG showed a-wave was normal, but b-wave of the patients was markedly decreased. None of the five missense mutations were detected in 16 affected and 14 unaffected family members.

CONCLUSIONThe molecular pathogenesis of ADCSNB in this family does not involve point mutations or deletions of these five sites, which indicates the heterogeneity of ADCSNB.

OBJECTIVETo study the inhibitory effects of Panax Notoginseng Saponins(PNS) on apoptosis induced by hypoxia/hypoglycemia and reoxygenation in cultured rat hippocampal neurons.

METHODApoptosis were measured by flow cytometry, intracellular free calcium concentration([Ca2+]i) was measured with confocal laser scanning microscopy, morphological changes and neuronal necrosis were observed with fluorescence microscope, and meanwhile the leakage of lactic dehydrogenase(LDH) was measured.

RESULTHypoxia/hypoglycemia cultures for 5 hours and reoxygenation induced neuronal apoptosis and necrosis, and significantly increased neuronal [Ca2+]i and the leakage of LDH. The effects were increased with the extending time of reoxygenation. PNS has could significantly decrease the percentage of neuronal apoptosis and necrosis, and reduce neuronal [Ca2+]i and the leakage of LDH.

CONCLUSIONPNS has inhibitory effect on neuronal apoptosis. This effect might be related to its effect of decreasing intracellular free calcium concentration.

OBJECTIVETo construct recombinant lentiviral vectors carrying Rheb gene and its mutant Rheb'D60K gene, and examine their expression in human liver cancer cells.

METHODSRheb gene was amplified by PCR to construct the recombinant plasmid LV31-Rheb-WT and LV31-Rheb-D60K. HEK-293 FT cells were contransfected with the recombinant lentiviral vector together with a lentiviral package plasmid to produce the lentiviral particles. The expression of PS6 protein was detected in the lentivirus-infected MCF-7 cells. The apoptosis of SK-HEP-1 cells transfected with LV31-Rheb-WT or LV31-Rheb-D60K was observed.

RESULTSThe recombinant LV31-Rheb-WT and LV31-Rheb-D60K vectors were confirmed by PCR and DNA sequencing. Western blotting showed that PS6 protein expression was increased in LV31-Rheb-WT-transfected cells while decreased in LV31-Rheb-D60K-transfected cells. LV31-Rheb-D60K-transfected SK-HEP-1 cells showed more obvious apoptosis after starvation than LV31-Rheb-WT-transfected cells.

CONCLUSIONLentiviral vectors carrying Rheb gene and its mutant has been successfully constructed, which can be useful in further investigation of the role of Rheb gene in cancer cells.

OBJECTIVETo evaluate the efficacy of porcine anti-human lymphocyte globulin (P-ALG) plus cyclosporine A (CsA) therapy for severe aplastic anemia (SAA).

METHODSForty-eight SAA patients (31 males, 17 females) including 17 very severe aplastic anemias (vSAA) were treated with ALG plus CsA between 1999 to 2009 in our hospital and the outcomes were analyzed retrospectively for early mortality, response rate and quality, survival rate, toxicity and complications.

RESULTSThe median age was 28 (13 - 64) years. The interval from diagnosis to treatment was 45 days. The median neutrophil count at diagnosis was 0.178 × 10(9)/L. Overall response was 83.3% (54.2% complete, 29.2% partial) with a median time of 90 (23 - 380) days. 10.4% died of infection within 30 days mainly of fungi infection. Only 1 patient relapsed 2 years after treatment. No clonal disease was found. The 1.5-year survival rate was 87.5%. vSAAs had less response, higher early mortality and less survival (64.7%, 29.4% and 51.8%, respectively) compared to that of SAA (93.5%, 0, 100%, respectively, P < 0.05). Grouped patients with different age, gender, intervals between diagnosis and treatment and pre-existing infections had similar response. The main side effects were fever and skin rash (52.1%), serum sickness (16.7%), impaired liver function (60.4%) and hemorrhage (2.1%). No treatment-related mortality was found.

CONCLUSIONP-ALG plus CsA is an ideal and well tolerated treatment for SAA but not for vSAA.

OBJECTIVETo evaluate the efficacy and safety of recombinant human thrombopoietin (rhTPO) combined with glucocorticoid in treatment of severe newly diagnosed primary immune thrombocytopenia (ITP).

METHODSFrom June 2009 to December 2012, 24 male patients and 38 female patients with the diagnosis of severe primary ITP in our hospital were randomized into trial group (31 cases) or control group (31 cases), the median age was 50 years (range: 21-84 years). Trial group was treated with rhTPO combined with glucocorticoid, and control group was treated with glucocorticoid only.

RESULTSAt the day 3, 7 and 14 from the beginning of treatment, the average platelet count (APC) in trial group[(35.5±24.9)×10⁹/L, (135.2±94.9)×10⁹/L and (192.0±109.1)×10⁹/L]were significantly higher than that in control group[(24.5±15.6)×10⁹/L, (78.2±121.9)×10⁹/L and (95.8±60.5)×10⁹/L, P=0.022, 0.009 and 0.001, respectively]. There was no significant difference in APC between the two groups at day 28 and 90 after treatment[(147.8±59.1)×10⁹/L vs (105.1±56.9)×10⁹/L, P=0.243; (137.4±52.3)×10⁹/L vs (104.3±59.8)×10⁹/L, P=0.568, respectively]. At the day 7, 14 and 28, the complete response rates in trial group were 61.3%, 87.1% and 80.6%, which were also significantly higher than that in control group (16.1%, 29.0% and 48.3%, P=0.000, 0.000 and 0.004, respectively). The median time to response in trial group was 3 days while in the control group was 5 days; the median duration of complete response in trial group was 76 days while in the control group was 54 days. In trial group, there were 4 cases treated with platelet transfusion, while in control group there were 11 cases, respectively.

CONCLUSIONFor patients with severe primary ITP, rhTPO combined with glucocorticoid could rapidly increase the platelet count, significantly improve the complete response rate and prolonged the effect with a low incidence of tolerable adverse events compared to single use of glucocorticoid. rhTPO combined with glucocorticoid could be a new therapeutic choice to those patients.

Objective:To explore the optimum time of ambulation of atrial fibrillation patients after radiofrequency ablation, to provide basis for patients' early postoperative rehabilitation.Methods:By convenient sampling method, a total of 120 patients with atrial fibrillation after radiofrequency ablation were collected at Yanghu Branch and City Branch of Changzhou Second People's Hospital from January 2020 to May 2021. They were divided into the early group, middle group and late group according to the random number table method, each group were 40 cases. All patients received routine postoperative intervention, the time of ambulation were 4, 6 and 12 h after operation in the early group, middle group and late group, respectively. The complication rate within 24 h after operation was compared among the three groups, and the comfort level of the three groups at 24, 48 and 72 h after operation was evaluated with Comfort Status Scale (GCQ).Results:Finally, 111 patients were included, including 37 in the early group, 38 in the middle group and 36 in the late group. There was no significant difference in the incidence of bleeding or hematoma, urinary retention, lumbago within 24 h after operation among the three groups ( P>0.05). The incidence of postural hypotension within 24 h after operation in the early group was 2.7% (1/37), which was lower than 21.1% (7/38) and 25.0% (9/36) in the middle and late groups, with a statistically significant difference ( χ2=4.86, 7.67, both P<0.05). At 48 and 72 h after operation, the scores of physiological dimension, psychological dimension and the total score of GCQ in the early group were (20.68 ± 3.07), (22.54 ± 3.35), (81.68 ± 6.11) and (22.54 ± 3.73), (24.38 ± 2.49), (84.92 ± 6.37), higher than those in the middle group (19.16 ± 2.19), (21.32 ± 2.27), (78.24 ± 5.58), (20.93 ± 2.85), (22.32 ± 2.04), (81.66 ± 6.56), and those in the late group (18.44 ± 1.50) (21.31 ± 1.99), (78.06 ± 4.32), (20.89 ± 2.25), (21.58 ± 1.86), (80.28 ± 6.44), the differences were statistically significant ( t values were 2.19-4.15, all P<0.05). Conclusions:Ambulation at 4 h after operation does not increase peripheral vascular complications, but can reduce the incidence of postural hypotension and improve the comfort of patients with atrial fibrillation after radiofrequency ablation.

OBJECTIVE: To develop and validate a risk prediction model of treatment failure in patients with peritoneal dialysis-associated peritonitis (PDAP). METHODS: We retrospectively analyzed the data of patients undergoing peritoneal dialysis (PD) in 3 dialysis centers in Jilin Province who developed PDAP between January 1, 2013 and December 31, 2019. The data collected from the Second Hospital of Jilin University and Second Division of First Hospital of Jilin University) were used as the training dataset and those from Jilin Central Hospital as the validation dataset. We developed a nomogram for predicting treatment failure using a logistic regression model with backward elimination. The performance of the nomogram was assessed by analyzing the C-statistic and the calibration plots. We also plotted decision curves to evaluate the clinical efficacy of the nomogram. RESULTS: A total of 977 episodes of PDAP were included in the analysis (625 episodes in the training dataset and 352 episodes in the validation dataset). During follow-up, 78 treatment failures occurred in the training dataset and 35 in the validation dataset. A multivariable logistic regression prediction model was established, and the predictors in the final nomogram model included serum albumin, peritoneal dialysate white cell count on day 5, PD duration, and type of causative organisms. The nomogram showed a good performance in predicting treatment failure, with a C-statistic of 0.827 (95% CI: 0.784-0.871) in the training dataset and of 0.825 (95% CI: 0.743-0.908) in the validation dataset. The nomogram also performed well in calibration in both the training and validation datasets. CONCLUSION The established nomogram has a good accuracy in estimating the risk of treatment failure in PDAP patients.

OBJECTIVETo explore the efficacy and safty of sorafenib in Child-Pugh class B to class C hepatocellular carcinoma (HCC).

METHODSIn this three-center open-label study from November 2011 to May 2013, we randomly assigned 189 patients with advanced Child-Pugh class B or C HCC patients into two groups, one group with 95 patient to receive sorafenib (400 mg a time, twice a day) and the other group with 94 patients to receive best supportive care. The primary end points were progression-free survival and overall survival.

RESULTSThe median progression-free survival was 2.2 months and 1.9 months in the sorafenib group and best supportive care group respectively (Hazard ratio in the sorafenib group, 0.55; 95% confidence interval, 0.40-0.75; P=0.002). The median overall survival was 4.0 months and 3.5 months in the sorafenib group and best supportive care group respectively (Hazard ratio in the sorafenib group, 0.48; 95% confidence interval, 0.35-0.68; P<0.001). The main adverse effect of sorafenib was rash and acne of the skin (in 51.7% patients). The incidences of severe rash, diarrhea, and dry skin were 5.6%, 5.6%, and 2.2% in the sorafenib group. One patient reached partial response in the sorafenib group.

CONCLUSIONSSorafenib is safe in patients with liver function impaired advanced HCC. It is effective in terms of progression-free survival and overall survival compared with best supportive care. Liver functions are the important predictive factors.
