Objective To observe the clinical effect of brachial plexus anesthesia shoulder manipulation solution combined with individualized treatment in treatment of periarthritis of shoulder.Methods 80 patients with periarthritis of shoulder were randomly divided into control group and observation group,40 cases in each group.The control group was given brachial plexus anesthesia shoulder manipulation solution,and the observation group was given brachial plexus anesthesia shoulder manipulation solution combined with individualized treatment.Joint function score and cure rate were compared before and after treatment in the two groups.Results The joint function score [(93.68 ±3.74)] and cure rate (62.50%) of the observation group were significantly higher than those in the control group[(79.35 ±3.21),35.00%] after 2 months treatment (t =1.57,3.86,χ2 =6.05,all P <0.05). Conclusion Brachial plexus anesthesia shoulder manipulation solution with individualized treatment has obvious effect in treatment of periarthritis of shoulder,and can effectively restore joint function in patients.

Objective To explore the timing of surgical intervention for severe acute pancreatitis (SAP). Meth-ods One hundred and fifty-seven cases with SAP treated in our hospital from March, 1998 to December, 2007 were analyzed retrospectively. Influence of surgical intervention and conservative treatment on curative rate were e-valuated in pancreatic necrotic area and with or without infected pancreatic necrosis. Results The overall curative rate of surgical treatment and conservative treatment was 80.4%, 87.1% respectively; the two methods had no sta-tistical difference. Conservative treatment was better than surgical treatment in patients with lesa than 30% necrotic area and surgical treatment was better than conservative treatment in patients with more than 50% necrotic area. But the two methods had no statistical difference in 30% ～ 50% necrotic area. Conservative management was better than surgical management in sterile pancreatic necrosis, but surgical management was better than conservative manage-ment in pancreatic necrosis with infection or suspection of infection. Conclusion Surgical intervention treatment plays an important role in SAP patients, we should combine pancreatic necrotic area and with or without infection to choose the timing of surgical intervention for severe acute pancreatitis.

Observe and study the morphological changes and effects on yoleperoxidase (MPO) of traditional Chinese medical complex Intestine-clearing Suppository (ICS) in preventing and treating ulcerative colitis (UC).Method.. Divide the experimental rats randomly into 6 groups, i.e., blank, salicylazosulfapyridine (SASP), model, high, middle and low dosage of ICS, except the blank group, makeother rats experimental UC model with albumen immunologic method of rabbit colon mucosa, further divide them randomly into 2 experimental groups, i. e. , prevention and treatment, afterwards at 2nd~21st day, give prevention group the medicine, 22nd~35th day, treatment group, then decapitate them and take the colon tissue, and observe it morphologically under optical microscope, measure active MPO, analyse statastic results. Result: Through general morphological observation ,we found there were serious congestion ,edema, mucosa erosion, many large ulcers in the rats of model group; less serious mucosa erosion and quantity of ulcers in SASP and low-dosage ICS groups: small ulcers, not serious mucosa erosion, low degree of congestion and edema in high-and middle-dosage ICS groups; the scores of inflammatory injury of ICS groups were markedly lower than that of model (P＜0. 01), meanwhile, the preventive and reating effectiveness of high-and middle-dosage groups was better than that of SASP (P＜0.05). Under the optical microscope, there were large area of mucosa coloboma in the rats of model group, the ulcer penetrated to muscular layer and serous coat; in SASP group and low-dosage ICS group, there were erosive mucosa and inflammatory cell infiltration, granulation on the base; in middle-and high-dosage groups, large part of colon mucosa recovered, granulation formed on the base, ulcers were obviously less than that in model group (P <＜0.01); there had marked difference compared with that in SASP group (P＜0.05). The MPO active values of high-and middle-dosage groups were markedly lower than that of model group (P ＜ 0.01). Conclusion: Traditional Chinese complex ICS had good prevention and treatment to rats UC, itseffectiveness was positively correlated with dosage and better than that of SASP suppository.

Objective To explore the clinical characteristics of primary central nervous system malignant lymphoma (PCNSML). Methods The clinical data of 22 cases of PCNSML were analyzed retrospectively.Results The patients in our study mainly presented with headache (16 cases), vomiting (11 cases), weakness of extremities (5 cases) and numbness (1 case). The tumors were supratentorial in 19cases, infratentorial in 3 cases and multiple in 5 cases. CT scan showed same density or high-density lesions with surrounding mild edema. Brain MRI demonstrated slight-hypointense lesion of 9 cases and isointense lesion of 5 cases on T1-weighted imaging. On the T2-weighted imaging, the lesions were slight-hyperintense in 11 cases and isointense in 3 cases. Enhanced scanning showed that the lesions were contrasted evenly and obviously on CT and MRI. Misdiagnosis was given preoperatively in 17 patients. The pathological examination revealed B cell malignant lymphoma in all cases. In 18 cases of follow-up, 5 patients with multiple lesions who only received stereotactic biopsy all died within 6 months, the mean survival time of 6 patients who were treated with total resection of the tumors and radiotherapy was 27 months, 4 patients treated with partial resection and ?-radiotherapy was 21 months, 4 patients treated with partial resection and radiotherapy was 10 months. The patient who was treated with only total resection of the tumor died in 11 months because of recurrent. Two patients with only partial resection died in 5 and 8 months, respectively.Conclusions There are no specific clinical manifestations of PCNSML and the disease is often misdiagnosed preoperatively. Although certain characteristic performance may be found on CT and MRI scans, the final diagnosis of this disease depends on pathological examination. Comprehensive treatments may prolong the survival time of the patients.

Objective To discuss the effect of microsurgery of intracranial arachnoid cyst. Methods 42 cases of intracranial arachnoid cyst treated with microsurgery were studied retrospectively.Results Total resection was performed in 23 cases and partial resection in 14 cases. 5 cases received partial resection and communication between cystic cavity and brain cistern. CT scans of 29 cases after operation showed completely obliteration or marked diminution in cystic size. The symptoms and signs of all the patients were improved significantly after a 1-year follow-up.Conclusion The effect of microsurgery of intracranial arachnoid cysts is satisfactory. It is important to communicate cystic cavity with subarachnoid space or brain cistern.

Ocular albinism type 1 (OA1),the most form of the ocular albinism,is an X-linked disorder mainly characterized by a severe reduction of visual acuity,hypopigmentation of the retina,photophobia,strabismus and nystagmus. The OA1 gene is located on chromosome Xp22.32 and the coding sequence is divided into nine exons. The OA1 gene codes for a 404 amino acid protein thought to be a melanosomal transmembrane glycoprotein. The OA1 protein is similar to the G protein-coupled receptors,but it's exact function is not clear. There are many mutations and deletions of the OA1 gene have been found.

AIM: To observe the effect of myocyte enhancer factor 2C (MEF2C) on the expression of substance P (Sub P) and neurofilament triplet L (NFL) in rat dorsal root ganglion cells (DRGn cells). METHODS: DRG neurons were dissociated and cultured, and then exposed to different concentrations of nerve growth factor (NGF, 10 μg/L, 30 μg/L, 100 μg/L or 200 μg/L) for 24 h. The neurons cultured in media with the lowest concentration of NGF (10 μg/L) served as control. Real time PCR was used for detecting the mRNA of substance P and NFL in the DRGn cells. Three MEF2C-siRNAs were transfected into PC 12 cell line by the way of chemical mediation. The best siRNA with the highest interference ratio was determined by real time PCR. The DRGn cells knocked out MEF2C gene were also transfected with siRNA, and the expressions of substance P and NFL were measured by real time PCR after stimulated with high concentration of NGF. RESULTS: The expressions of substance P and NFL increased in primary cultured rat DRG neurons in a dose-dependent manner of NGF stimulation. The expression level of MEF2C in experimental group was lower by 50% than that in control group. No change of cyclic AMP response element-binding protein (CREB) was observed. The substance P decreased by 41% in experimental group than that in control group at the same time point. The NFL was decreased by 61%. CONCLUSION: NGF may promote the synthesis of substance P and NFL in rat DRGn cells. MEF2C regulates the expression of substance P and NFL in DRGn cells in rat embryo and MEF2C may be a critical transcriptional factor involved in the airway hyperresponsiveness.

Objective To investigate the change of umbilical cord blood gas from early-stage neonates with pregnancy-induced hypertension syndrome (PHIS) affected mothers and its influence upon internal environment of body,and to evaluate the significance of postpartum umbilical cord blood gas analysis.Methods Retrospective study of 101 neonates(born of 97 PHIS-affected mothers),41 cases of mild group,34 cases of moderate group,26 cases of severe group,and enrolled 52 neonates born of non-PHIS mothers as the control group.Prior to neonate's first breath,umbilical cord artery blood gas analysis was performedimmediately to determine the values of pH,arterial carbon dioxide partial pressure (PaCO2),arterial oxygen tension (PaO2),HCO3-,base excess (BE),and Apgar score was completed within 1 min after birth.Results The pH,PaO2,HCO3-,BE in severe group was significantly lower than those in mild group,moderate group,and control group [7.16 ± 0.18 vs.7.25 ± 0.09,7.22 ± 0.11,7.29 ± 0.08 ; (12.01 ± 2.75) mmHg (1 mmHg =0.133 kPa) vs.(18.35 ± 1.75),(14.21 ± 2.01),(22.23 ± 1.45) mmHg; (17.11 ± 2.42) mmoFL vs.(19.82 ±3.85),(17.32 ± 3.21),(22.56 ± 3.38) mmol/L; (-9.15 ± 0.32) mmol/L vs.(-7.95 ± 0.60),(-7.21 ± 0.08),(-6.76 ± 0.03) mmol/L] (P ＜ 0.05),the PaCO2 in severe group was significantly higher than that in mild group,moderate group,and control group [(61.84 ± 32.93) mmHg vs.(54.48 ± 12.82),(58.38 ± 15.32),(51.66 ± 10.52) mmHg] (P ＜ 0.05),Apgar score 1 min after birth was positively correlated with umbilical arterial pH (P ＜ 0.05),the lower Apgar score,the lower pH.Among 65 cases of Apgar score ≤ 7 scores,37 cases of acidosis (pH ＜ 7.20),the incidence rate was 56.92％ (37/65) ; among 88 cases of Apgar score ≥ 8 scores,11 cases of acidosis,the incidence rate was 12.50％ (11/88),the difference was statistically significant (P ＜ 0.01).Conclusions Umbilical cord blood gas analysis is more objective than Apgar score,which could reflect neonate's hypoxia-ischemia degree bore of PIHS mothers,as well as contributed to the assessment of neonate' s prognosis.Conventional umbilical cord blood gas analysis is necessary for neonates bore of PIHS-affected mothers.Enhanced monitoring should be performed in a timely manner on those neonates born after intrauterine distress signs or with low Apgar score,the prevention and therapy as early as possible can improve the quality of birth.

Objective To compare enteral nutrition (EN) and total parenteral nutrition (TPN) in the treatment of severe acute pancreatitis(SAP) elucidate the advantage of EN. Methods Fifty-nine patients were assigned to TPN and EN groups. The nutritional index was detected, and the therapeutic efficacy was reviewed comparetively. Results After giving the nutritional support, the serum contents of albumin, pre-albumin, transferrin and beamoglobin were increased obviously (P < 0.05);and prealbumin, transferrin had statistical difference between the TPN and EN groups(P <0.05). APACHE Ⅱ score was lowered significant-ly in the EN group, comparing with the TPN group (P <0.05). In the EN group, complications, infection rate, food intake time, and hospitalization costs were significantly lower compared with the TPN group(P< 0.05), although mortality rate, hospital stay days had no statistical significance (P > 0.05). Conclusion EN is on ideal modality of nutrition support in SAP patients, which has many advantages in improving nu-tritional status, preserving gut mucosa barrier, decreasing bacterium and toxin shifting, regulating inflamma-tory and infective response, decreasing costs in the hospital.
