BACKGROUND & OBJECTIVE: Oldenlandia diffusa (Bai Hua She She Cao) is one of the herbs most commonly used in traditional Chinese medicine for treating cancer. Various studies using the herb alone or in combination with other therapy plans have evidenced the effectiveness of the herb in the management of cancers of different tissue origin. However, the mechanisms underlying its anti-cancer activity are unknown. In the present study, we attempted to investigate the apoptotic activity of crude extracts of the herb as well as the possible molecular pathways. METHODS: We incubated human promyelocytic leukemia cell line HL60 cells with ethanol or aqueous extracts of the herb, and determined the levels of intracellular superoxide at 2 and 4 hours as well as caspase activity at 3, 6 and 8 hours using photospectrometry. Cancer cell survival and apoptosis were quantified at 24 hours by using MTT and flow cytometry analyses respectively. RESULTS: We found that it dose-dependently inhibited the cancer cell growth in MTT assay. Flow cytometry analysis revealed that it elicited significant production of sub-G(1) population of the cells, indicating the extract-evoked cell apoptotic death. The LD(50) of the ethanol extract was estimated to be approximately 320 microg/ml. Moreover, treatment of the cancer cells with the ethanol component markedly increased the production of superoxide within few hours. Significant elevation in the protease activities of caspases-2 and -3 were detected at as early as 3 and 6 hours respectively. CONCLUSION: Our results show that the ethanol extract of the herb effectively evokes cancer cell apoptosis, possibly through burst-mediated caspase activation.

Objective: To determine the trace elements content in the selected medicinal plants, namely, Eryngium foetidum L., Mimosa pudica L., Polygonum plebeium, and Prunus cerasoides D. Don traditionally used by the natives of the Mizoram, one of the north eastern states in India as their folklore medicines for curing skin diseases like eczema, leg and fingers infection, swelling and wound. Methods: A 3 MeV proton beam of proton induced X-ray emission technique, one of the most powerful techniques for its quick multi elemental trace analysis capability and high sensitivity was used to detect and characterized for trace elements. Results: The studies revealed that six trace elements, namely, Fe, Zn, Cu, Mn, V, and Co detected in mg/L unit were present in varying concentrations in the selected medicinal plants with high and notable concentration of Fe, Zn, Mn and appreciable amount of the Cu, Co and V in all the plants. Conclusions: The results of the present study support the therapeutic usage of these medicinal plants in the traditional practices for curing skin diseases since they are found to contain appreciable amount of the Fe, Zn, Cu, Mn, V and Co.

It is conventionallyseen in cases of the high energy injuries of the pelvis andlower limb. The accumulation of extravasated blood,secondary to fracture and soft tissue damage may causeinternal degloving injury, skin necrosis, soft tissue damageand acute osteomyelitis. We report here the clinical andradiological features in a 32-year-old male referred from theemergency department of a tertiary hospital who hadsustained high energy motor vehicle accident. Onexamination, there was a fluctuant, mobile, non-tendersubcutaneous mass over the distal arm with suspicion ofinternal degloving injury. Plain radiographs showed nofractures. Ultrasound showed a fluid collection with thepresence of septations and echogenic debris within thecollection. Extravasation was noted between subcutaneoustissue layer and fascia at the posterolateral aspect of thearm. Wound debridement under general anaesthesia wascarried out. Intraoperative findings reported a significantamount of thick serous fluid with necrotic debris. Unhealthyskin and fat layers were debrided. Underlying muscles werefound to be healthy. The results of the intraoperative fluidculture and sensitivity showed no growth. Negative pressurevacuum dressing was carried out. After five cycles ofvacuum dressing, the wound showed signs of healing withan improved range of motion of the elbow. Orthopaedicsurgeons need to be vigilant of the possibility of MLL in theupper limb as a differential diagnosis in the management ofhigh energy trauma.

Intramedullary nailing is the preferred method of closed shaft fracture fixation of long bones. One of the most dreaded complications to occur following internal fixation of a lower limb fracture is pseudo- or false aneurysm which can lead to the loss of the limb due to acute ischemia. This diagnosis is made by contrast angiogram of the limb. Pointers to the diagnosis include absent distal limb pulsation as well as other signs of acute ischemia post trauma or surgery. We present a case of development of pseudo-aneurysm in an elderly patient following open reduction and internal fixation of a femoral fracture. This case report outlines a prompt multidisciplinary approach of management in a rare case of pseudoaneurysm post fixation of long bone.

The Asia-Pacific region carries a high disease burden, with over half of the global diabetic population residing in this region. Increasing evidence shows that without targeted intervention, the progression from impaired glucose tolerance (IGT) to type 2 diabetes occurs more frequently in Asians compared with Caucasians. Furthermore, IGT is independently associated with an increased risk of cardiovascular disease, and should be managed as early as possible. Because diabetes is now a major public health issue, strategies aimed at prevention and treatment are urgently required. Lifestyle modification, including weight loss, dietary changes and increased physical activity, play a major role in controlling the disease. Significant evidence also supports the effectiveness of a combination of lifestyle modification and pharmacologic therapy, such as metformin, in delaying the onset of diabetes. Although the importance of lifestyle interventions is well recognized throughout Asia, many countries do not have formal recommendations to guide the diagnosis and management of individuals at risk of progression to diabetes. At a recent regional meeting, experts from the Asian region convened to develop consensus recommendations to guide clinicians in the management of Asian patients with pre-diabetes. These consensus recommendations provide a clear and concise approach to the management of individuals with IGT based on the available evidence and current best clinical practice.

Knee osteoarthritis is the commonest cause of knee pain in the elderly. It is characterized by unresolved pain, limitation of motion and reduced quality of life. Total knee arthroplasty (TKA) is a safe and effective method in treating chronic knee osteoarthritis. We report a rare case of a seventy-seven-year-old Chinese female with multiple comorbidities and bilateral degenerative osteoarthritis who had sought services of traditional and complementary medicine (TCM) for pain relief. The patient experienced unresolved pain and superficial skin scars following the unregulated procedure. This paper aims to outline the importance of awareness among surgeons regarding the unregulated practice of TCM that may exacerbate chronic osteoarthritis, joint synovitis, influence the surgical approach for future procedures with the presence of scars and prosthetic joint infection risk.
