Objective To investigate the effect of intravenous fluid infusion combined with water throuth gastrointestinal tract in treating the patients with hyperosmolar hyperglycemic state(HHS).Methods 30 HHS pa- tients were recruited.All the patients were given water throuth gastrointestinal infusion while they were administrat- ed continuously intravenous infusion.Laboratory parameters such as serum natrium,serum potasium,serum glucose and serum osmolarity ect were monitored at the admission and after treatment.Results Serum glucose and serum osmolarity of HHS patients were decreased smoothly at the speed of less than 3 mmol?L~(-1).h~(-1)during the first 12 hours after treatment.After 48 hour-treatment,serum natrium,serum potassium and serum osmolarity recovered to normal levels except 2 deaths,serum glucose decreased to(10.8?5.2)mmol/L.Conclusion Intravenous fluid infu- sion combined with water throuth gastrointestinal tract for the patients could lower smoothly serum glucose and serum osmolarity and decrease the mortality of the HHS patients.

OBJECTIVETo summarize the experience of repair and reconstruction of penile defects as a result of devastating deep burn.

METHODSTwenty-four patients with penile defects in early or late (a half year after wound healed, the same below) stage after burn were involved. Their suspensory ligaments of penis were dissected to lengthen the penis after escharotomy with the necrotic distal part removed. The wounds formed after lengthening were covered with lower abdominal skin flap, scrotal or internal pudendal artery flap. Ten patients underwent surgery within 30 days after burn; the other 14 patients underwent surgery in the late stage. The condition of flaps and complications after surgery were observed. The lengths of penis of patients in flaccid and erection state were measured before surgery and at follow-up period. The sensory function of penile skin, the erectile function of the penis, and sexual intercourse activity of patients were followed up.

RESULTSAll the flaps survived except two, in whom areas of 1.0 cm x 0.5 cm and 1.5 cm x 1.0 cm of necrosis at distal parts were found, and they healed after dressing changes. Patients were followed up for 2 to 5 years. The length of penis in flaccid state was (7.4 +/- 1.6) cm, which was (5.3 +/- 1.4) cm longer than that before surgery (P < 0.01). The length of penis in erection state was (9.7 +/- 1.2) cm. The sensory function of penis recovered gradually about half year after surgery with well preserved erectile function. Except one who did not try to have sexual intercourse again, all the other married patients and their spouses were satisfied or quite satisfied with sexual intercourse activity.

CONCLUSIONSPenis elongation combined with skin flap grafting is a good method for the treatment of penile defects due to devastating deep burn. Suitable length and erectile function of penis can be preserved with this method.

OBJECTIVEPeriodic paralysis (PP) is one type of skeletal muscle channelopathies characterized by episodic attacks of weakness. It is usually classified into hyperkalemic periodic paralysis (HyperPP), hypokalemic periodic paralysis (HypoPP) and normokalemic periodic paralysis (NormoPP) based on the blood potassium levels. HypoPP is the most common type of these three and NormoPP is the rarest one. The aim of this study was to explore the clinical and genetic features of a Chinese family with normokalemic periodic paralysis (NormoKPP).

METHODClinical features of all patients in the family with NormoKPP were analyzed. Genomic DNA was extracted from peripheral blood leukocytes and amplified with PCR. We screened all 24 exons of SCN4A gene and then sequence analysis was performed in those who showed heteroduplex as compared with unaffected controls.

RESULT(1) Fifteen members of the family were clinically diagnosed NormoKPP, and their common features are: onset within infacy, episodic attacks of weakness, the blood potassium levels were within normal ranges, high sodium diet or large dosage of normal saline could attenuate the symptom. One muscle biopsy was performed and examination of light and electronic microscopy showed occasionally degenerating myofibers. (2) Gene of 12 patients were screened and confirmed mutations of SCN4A genes--c. 2111 T > C/p. Thr704Met.

CONCLUSIONThe study further defined the clinical features of patients with NormoKPP, and molecular genetic analysis found SCN4A gene c. 2111 T > C/p. Thr704Met point mutation contributed to the disease. In line with the autosomal dominant inheritance laws, this family can be diagnosed with periodic paralysis, and be provided with genetic counseling. And the study may also help the clinical diagnosis, guide treatment and genetic counseling of this rare disease in China.

OBJECTIVETo evaluate the efficacy and safety of autologous peripheral blood stem cell transplantation (auto-PBSCT) after high dose melphalan in patients with POEMS syndrome.

METHODSNine patients including 6 males and 3 females received 10 auto-PBSCT after high dose melphalan in our hospital from June 2005 to October 2009. The median age at transplantation was 44 (39 - 48) years. The median time from onset of disease to transplantation was 12 (5 - 60) months. Peripheral stem cells were mobilized by G-CSF alone in one patient and 8 patients by G-CSF plus chemotherapy. Two patients were conditioned by melphalan 140 mg/m(2) and 7 by melphalan 200 mg/m(2). The median number of MNC was 3.75 (1.05 - 8.33) × 10(8)/kg, and that of CD34(+) cell was 5.37 (1.32 - 10.90) × 10(6)/kg.

RESULTOne patient received tandem auto-PBSCT and others received single one. Stem cell engrafted in all but 1 patient who died of severe infection and acute renal failure on day 9 after transplantation. Eight patients were evaluable for response. The median time to ANC ≥ 0.5 × 10(9)/L and platelet ≥ 20 × 10(9)/L was 10 (9 - 11) and 11.5 (9 - 14) days respectively. Two patient reached negative immunofixation electrophoresis (IFE) after stem cell mobilization and transplantation respectively, and the other 6 remained IFE postive after auto-PBSCT. Skin changes and edema of lower extremities were improved in 5 of 6 patients, lymphadenopathy relieved in 1 and papilledema improved in 2 of 3 patients. All but 1 patient achieved gradual neurologic improvement after transplantation.

CONCLUSIONPBSCT is an effective and safe therapy for POEMS syndrome patients with low treatment related mortality.

BACKGROUNDRituximab is used extensively in combination with chemotherapy to cure non-Hodgkin's lymphoma (NHL), and not only accelerates short-term improvement, but also prolongs patient survival and decreases receptor relapse. The aim of this study was to evaluate the impact of Fcgamma IIIA (FcgammaRIIIA) gene polymorphisms on the response to rituximab therapy for newly diagnosed B-cell lymphomas.

METHODSPatients with newly diagnosed histologically-proven CD20-positive B-cell lymphoma were eligible for the study. All of the patients received rituximab combined with chemotherapy (CHOP). The FcgammaRIIIA type was analyzed by PCR. The initial efficacy was assessed after 6 cycles and the long-term survival was determined.

RESULTSThirty-four patients were recruited between October 2005 and April 2006. The FcgammaRIIIA distribution was as follows: 11 patients were VV, 5 were FF, and 18 were VF. After a median of 6 cycles (range 4-8) of rituximab combined chemotherapy, the overall response rate was 79% (82% in the VV group, 83% in the VF group, and 60% in the FF group; P=0.04). After a median follow-up time of 37 months (range 34-41), there were 12 relapses among 27 responders (44%); 5 of 9 patients (5/9) in the VV group, 5 of 15 patients (33%) in the VF group, and 2 of 3 patients (2/3) in the FF group (P=0.21). The 1-year overall survival in the VV, FF, and VF groups was 80%, 60%, and 80%, respectively, and the 3-year overall survival was 58%, 40%, and 69%, respectively (P=0.08). After analysis by COX regression, only the international prognosis index and response to initial treatment were significantly related to overall survival.

CONCLUSIONSThe distribution of FcgammaRIIIA polymorphisms in this B-cell lymphoma population shows that VF is most frequently expressed, followed by VV and FF. Patients with the FcgammaRIIIA VV and VF types are more sensitive to the initial treatment of rituximab combined with chemotherapy and have superior long-term survival compared with those with FF. Nevertheless, FcgammaRIIIA polymorphisms do not predict prognosis independently.

OBJECTIVETo investigate the HCV genotypes distribution in northern and southern cities in China and the difference between patients infected with HCV by transfusion and non-transfusion routes.

METHODSThe HCV genotypes of the patients with chronic hepatitis C from 9 cities belonging to different regions were genotyped by the PCR products of 5 prime untranslated region NTR digested with restriction endonucleases, and the HCV genotypes distribution among different cities or between the patients infected with HCV through transfusion and other routes was analyzed.

RESULTSThe HCV genotypes of 214 in 219 cases were determined; 197 patients were infected with monogenotype HCV. The major epidemic genotypes of HCV isolates in China were 1b (76.64%) and 2a (18.22%), but 5.14% of patients were infected with HCV belonging to genotype 3b and this was the first report that there is genotype 4a in China. The HCV genotype distribution was not different in northern and southern areas, but was significantly different between patients infected with HCV through transfusion and non-transfusion routes (P=0.036). In patients infected trough transfusion, the rates of monogenotype HCV infection and genotype 1b were 93.88% and 76.87%, respectively, which were higher than those (86.57% and 58.21%) in the patients infected with HCV through non-transfusion routes. The rate of patient infected with mixed genotype HCV strains in non-transfusion group was 13.43%, which was higher than that (6.12%) of patients in transfusion group.

CONCLUSIONThe HCV genotype distribution in northern and southern regions were similar, but was significantly different between the patients infected through transfusion and other routes.

In this study, we investigated the inhibitory effect of SYT-1, a new compound of tetrahydroisoquino-line, on tumor cell proliferation and underlying mechanisms. Cell counting kit-8 (CCK-8) method was used to detect cell proliferation; clone formation experiment was used to detect cell clone formation ability; JC-1 probe was used to detect cell mitochondrial membrane potential; 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) probe was used to detect intracellular reactive oxygen species; Annexin V-FITC/PI (fluorescein isothiocyanate/propidium) counterstaining method was used to detect apoptosis; Western blot assay was used to detect the expression level of related proteins. The experimental results show that SYT-1 has a significant inhibitory effect on the proliferation of six human-derived cancer cells. Among them, the inhibitory effect on breast cancer MCF-7 cells is the strongest, the half maximal inhibitory concentration (IC₅₀) of SYT-1 of 48 h administration on MCF-7 cells is 5.87 μmol·L^-1, which is better than that of cisplatin (8.92 μmol·L^-1). Further studies have shown that SYT-1 can dose-dependently inhibit the monoclonal formation ability of MCF-7 cells, and can cause the mitochondrial membrane potential of the cells to decrease and the level of reactive oxygen species to increase. In addition, SYT-1 can significantly inhibit the activation of PI3K-Akt (phosphatidylinositol 3-kinase/protein kinase B) signaling pathway and induce apoptosis of MCF-7 cells. The above research results show that, as a new type of tetrahydroisoquinoline compound, SYT-1 has the potential to inhibit tumor cell proliferation.
