1.Somatosensory evoked potentials in patients with diabetes mellitus
Chinese Journal of Pathophysiology 1986;0(03):-
Using the average technique of the electronic computer, we recorded the somatosensory evoked Potentials (SEPs) by electrical stimulation of median nerve (MN) and posterior tibial nerve (PTN) in twenty-three normal subjects and twenty-five diabetic patients. The peak latencies of SEPs components were prolonged, and the afferent conduction velocities of MN and PTN were reduced in most patients. In some patients, the central conduction time (N13-N20 and P40-N80 conduction time) was prolonged. Besides, there was a significant change in the shape of triphasal potentials recorded from Erb's point.and popliteal fossa. These results suggest: there not only was abnormality of conductive function of peripheralnerves, but also, the conductive function of central nervous system might be involved in diabetes mellitus.
2.Study on the Relationship between the Perioperative Application of Antibiotics in Caesarean Operation and Neonatal Hyperbilirubinemia
China Pharmacy 2015;(23):3273-3274,3275
OBJECTIVE:To investigate the relationship between the perioperative application of antibiotics in caesarean opera-tion and neonatal hyperbilirubinemia,and to provide reference for reducing the incidence of neonatal hyperbilirubinemia. METH-ODS:264 cases of cesarean section women were randomly divided into control group and observation group,with 132 cases in each group. Control group was given antibiotics after operation,and observation group was given prophylactic application of antibi-otics before operation,and equivalent dose of intravenous injection after operation. Postoperative maximum and average tempera-ture,white blood cell(WBC),neutrophils(NEUT),complications and economic index were compared between 2 groups after op-eration. RESULTS:There was no statistically significant difference in postoperative maximum and average temperature,WBC count,NEUT proportion,wound infection and fever rate between 2 groups (P>0.05). The costs of medication,drug dosage per capita,hospital stay and the incidence of neonatal hyperbilirubinemia in observation group were significantly lower than in control group,with statistical significance (P<0.05). CONCLUSIONS:The perioperative standard use of antibiotics in caesarean opera-tion could effectively reduce the incidence of postoperative neonatal hyperbilirubinemia and hospitalization cost,and cut down treat-ment time. It also has a high economic value and worthy of promotion.

5.Fetal inlfammatory response syndrome and neonatal diseases
Journal of Clinical Pediatrics 2013;(9):801-804
The fetal inlfammatory response syndrome (FIRS) is a subclinical condition characterized by systemic acti-vation of the fetal innate immune system with a large number of pro-inlfammatory cytokines released. FIRS is the fetal coun-terpart of the systemic inlfammatory response syndrome (SIRS) described in adults. Intrauterine infection is the most common reason of FIRS. FIRS has been implicated as a cause of preterm labor, preterm white matter injury, bronchopulmonary dyspla-sia (BPD) and necrotizing enterocolitis (NEC).

Objective To evaluate mid-term clinical effects of laparoscopic intraperitoneal onlay mesh herniorrhaphy (IPOM) for adult inguinal hernia. Methods A retrospective analysis was made on 546 cases of inguinal hernia treated by IPOM (603 sides) between June 2002 to December 2004. We closed the hernia sac by the lift-insert method following with the implantation of the Prolene mesh with the help of a stapler. Results The operation was successfully completed in all the cases, except for 2 cases of conversions to open surgery because of difficulties in covering the defects. There were no intraoperative complications, and 5 cases of postoperative seroma which subsided after physical therapy. The operative time was 25~40 min (mean, 31 min), and the hospital stay was 36~72 h (mean, 46 h). Follow-up observations for 18~48 months (mean, 28 months) found 6 cases of recurrence, with the recurrence time at 30~45 months (mean,38.2 months). The racurrence rate was 0.995%. Conclusions Laparoscopic intraperitoneal onlay mesh herniorrhaphy a minimally invasive method with reliable outcomes, low recurrence rate, and rapid recovery.

The indirect pathway of the somatic afferent elements from trigeminal nerve (TGN) to nucleus tractus solitarii (NTS) was studied with the light and electron microscopic HRP transganglionic and retrograde tracing. After HRP was injected into NTS at the level of obex, the retrogradely labeled cells were mainly found in the interstitial nucleus buried in the spinal tract of TGN along caudal subnucleus. The interstitial nucleus was also the terminating area of the primary afferent fibers of lingual and inferior orbital nerves. Under electron microscope, it was found that the primary afferent terminals of lingual and inferior orbital nerves formed synapses on the dendrites of neurons in the interstitial nucleus. Moreover, in cellular architecture, the interstitial nucleus and the superficial laminae of the caudal nucleus of TGN were similar and continuous with each other. Hence, the pathway from the TGN to NTS via the interstitial nucleus is consisted of two neurons and the sensations transmitted through this pathway may be considered to be somatic. It is presumed that this pathway composed of two neurons might modulate the visceral afferent function in NTS when certain points in the skin area innervated by TGN were acupunctured.

Ovarian neoplasms,composed predominantly or exclusively of small round cells with scant cytoplasm,is relatively rare.However,there is a wide range of differentiation,and pathologists often struggle to make a correct diagnosis because of its overlapping histological features.Perhaps the best known neoplasm of this kind is ovarian small cell carcinoma of the hypercalcemic type,which may be confused with a wide range of neoplasm from sex cord-stromal tumor to neoplasm in the family of small round blue cell tumor to various undifferentiated malignancies.Small cell carcinoma of the pulmonary type may also arise from the ovary,and this may be a component of a typical ovarian surface epithelial-stromal tumor.Other small cell neoplasm that may arise within the ovary or involve the ovary includes intra-abdominal desmoplastic small round cell tumor,metastatic small cell carcinoma,peripheral primitive neuroectodermal tumor,and endometrial stromal sarcoma.In this review,the morphologic features of some of these neoplasms are described,as well the value of immunohistochemistry and other ancillary techniques in establishing a diagnosis.
